problems which peep into the future. Also, the coaching is very systematic, well -
planned and absolutely time bound. For a change, say good - bye to mechanical
learning. I am sure you will feel that the study is a pleasurable job and not a painful
exercise.

Each Topic of Costing & Financial Management is divided in to three parts :

(A) Theory Section : This section covers theory related to the topic.
(B) Classwork Section : This section covers good number of quality problems which
will be solved in the classroom.
(C) Revision Questions : Solving questions of this section will help in revising the whole
chapter.
(D) Theory for Exam : This section covers important theory questions relevant for
your IPCC exam.
(E) Homework Section : This section covers good number of problems. Students are
strongly advised to solve these problems.

Notes:
1. Variable Cost: It is directly related to production. It is also known as product cost. For
e.g. Direct Material, Direct Labour, Direct Expenses.
Variable cost per unit normally remains same. Total variable cost keeps on changing.
If production is increased then total variable cost will increase & if production is
decreased then total variable cost will decreased.
2. Fixed Cost: It is related to period & not related to product. It is also known as period
cost. For e.g. Salary, Rent etc.
Total amount of Fixed Cost remains same. Fixed cost per unit keeps on changing.
If production is increased then Fixed cost per unit will decrease & if production is
decreased then Fixed cost per unit will increased.
3. Semi Variable Cost: It is also known as Semi Fixed Cost. It is neither variable nor Fixed.
It remains same upto certain level of Activity and then it will change.
Sometimes semi variable can be divided into two parts i.e. Variable & Fixed.
For e.g. Telephone Expenses.
4. Stock Valuation: In Cost Accounting stock is to be valued at Cost Price.
Cost Price means what?
(A) Closing stock of Raw Material → It is to be valued at purchase price of Raw
Material, purchase price of Raw Material also includes expenses related to
purchase.
(B) WIP → Valuation of WIP includes Direct Material + Direct Labour + Direct
Expenses + Factory Overheads.

3
 INTER CA. – COSTING

(C) Finished Goods → It is to be valued at cost of production. (Direct Material + Direct

Labour + Direct Expenses + Factory Overheads + Administrative Overheads.
5. Financial expenses & Financial incomes are to be ignored in cost accounting.
E.g. of Financial Expenses: Bad debts, Cash discount allowed, Loss on sale of Assets,
Interest, Provision for Income - tax etc.
E.g. of Financial incomes: Bad debts recovered, Interest received, Dividend received,
Rent received, Profit on Sale of Assets etc.
6. Disputed Expenses: E.g. Bad debts, Cash discount allowed, Interest, etc. {These
Expenses can be considered as Financial expenses or It can be recorded in Cost
Accounting}.
7. Notional Expenses are to be recorded in Cost Accounting only.
For e.g. Rent of Premises owned by the company i.e. notional rent.

IMPORTANT THEORY QUESTIONS FOR EXAMINATION

Question 1
Define the terms ‘cost centre’ and ‘cost unit’.

Answer
Cost Centre: The term cost centre is defined as a location, person or an item of equipment
or a group of these for which costs may be ascertained and used for the purposes of cost
control. Cost centres can be personal cost centres, impersonal cost centres, operation
cost centres and process cost centres.
Cost Unit: The term cost unit is defined as a unit of quantity of product, service or time (or
a combination of these) in relation to which costs may be ascertained or expressed. It can
be for a job, batch, or product group.

Question 2
Given below is a list of ten industries. Give the method of costing and the unit of cost against
each industry.
(i) Nursing Home (vi) Bridge Construction
(ii) Road Transport (vii) Interior Decoration
(iii) Steel (viii) Advertising
(iv) Coal (ix) Furniture
(v) Bicycles (x) Sugar company having its own sugarcane fields.

Answer
Industry Method of costing Unit of cost
(i) Nursing Home Operating Per Bed per week or per day
(ii) Road transport Operating Per Tonne Kilometer or per mile
(iii) Steel Process Per Tonne
(iv) Coal Single Per unit
(v) Bicycles Multiple Each unit
(vi) Bridge construction Contract Each contract
(vii) Interior Decoration Job Each Job
(viii) Advertising Job Each Job
(ix) Furniture Multiple Each unit

13
 INTER CA. – COSTING

Question 3
Distinguish between:
(i) Cost Unit and Cost Centre
(ii) Cost Centre and Profit Centre

Answer
(i) Distinction between Cost Unit and Cost Centre
The term Cost Unit is defined as a unit of quantity of product, service or time (or a
combination of these) in relation to which costs may be ascertained or expressed. It
can be for a job, batch, or product group.
The term Cost Centre is defined as a location, person or an item of equipment or
a group of these for which costs may be ascertained and used for the purposes of
Cost Control. Cost Centres can be personal Cost Centres, impersonal Cost Centres,
operation cost and process Cost Centres.
Thus each sub-unit of an organisation is known as a Cost Centre, if cost can be
ascertained for it. In order to recover the cost incurred by a Cost Centre, it is necessary
to express it as the cost of output. The unit of output in relation to which cost
incurred by a Cost Centre is expressed is called a Cost Unit.
(ii) Cost Centre and Profit Centre
A Cost Centre is the smallest segment of activity or the area of responsibility for
which costs are accumulated. A Profit Centre is that segment of activity of a business
which is responsible for both revenue and expenses and discloses the profit of a
particular segment of activity.
Important points of distinction between Cost Centre and Profit Centre are as below:
(a) Cost Centres are created for accounting convenience of costs and their control.
Whereas a profit centre is created because of decentralisation of operations.
(b) A Cost Centre does not have target costs but efforts are made to minimise
costs, but each profit centre has a profit target and enjoys authority to adopt
such policies as are necessary to achieve its targets.

Question 4
List down any eight factors that you will consider before installing a costing system.

14
 INTER CA. – COSTING

Answer
The eight factors which must be considered before installing a Costing System are listed
below:
(i) Nature of business: The system of costing to be introduced should suit the general
nature of business.
(ii) Layout aspects: The size and layout of the organisation should be studied by the
system designers.
(iii) Methods and procedures in vogue: The system designers should also study various
methods and procedures for the purchase, receipts, storage and issue of material.
They should also study the methods of wage payment.
(iv) Management’s expectations and policies: The system of costing should be designed
after a careful analysis of the organisational operations, management’s expectation
and the policies of the concern.
(v) Technical aspects: The technical aspects of the business should be studied thoroughly
by the designers. They should also make an attempt to seek the assistance and
support of the supervisory staff and workers of the concern for the system.
(vi) Simplicity of the system: The system of costing to be installed should be easy to
understand and simple to operate. The procedures laid down for operating the
system should be easily understood by operating system.
(vii) Forms standardisation: Various forms to be used by the costing system for various
data / information collection and dissemination should be standardised as far as
possible.
(viii) Accuracy of data: The degree of accuracy of data to be supplied by the system should
be determined.

Question 5
Outline the steps involved in installing a costing system in a manufacturing unit. What
are the essentials of an effective costing system?

Answer
The main steps involved in installing a costing system in a manufacturing unit may be
outlined as below:
(i) The objectives of installing a costing system in a manufacturing concern and the
expectations of the management from such a system should be identified first. The
system will be a simple one in the case of a single objective but will be an elaborate
one in the case of multiple objectives.

15
 INTER CA. – COSTING

(ii) It is important to ascertain the significant variables of the manufacturing unit

which are amenable to control and affect the concern. For example, quite often
the production costs control may be more important than control of its marketing
cost. Under such a situation, the costing system should devote greater attention to
control production costs.
(iii) A thorough study to know about the nature of business, its technical aspects ;
products, methods and stages of production should also be made. Such a study will
facilitate in selecting a proper method of costing for manufacturing unit.
(iv) A study of the organisation structure, its size and layout etc., is also necessary.
This is useful to management to determine the scope of responsibilities of various
managers.
(v) The costing system should be evolved in consultation with the staff and should be
introduced only after meeting their objections and doubts, if any. The co-operation
of staff is essential for the successful operation of the system.
(vi) Details of records to be maintained by the costing system should be carefully worked
out. The degree of accuracy of the data to be supplied by the system should be
determined.
(vii) The forms to be used by foreman, workers, etc., should be standardised. These forms
be suitably designed and must ensure minimum clerical work at all stages.
(viii) Necessary arrangements should be made for the flow of information/data to all
concerned managers, at different levels, regularly and promptly.
(ix) Reconciliation of costs and financial accounts be carried out regularly, if they are
maintained separately.
(x) The costing system to be installed should be easy to understand and simple to
operate.
Essential of an effective costing system: The essential features that an effective costing
system should possess are as follows :
(a) Costing system should be tailor made, practical, simple and capable of meeting the
requirements of a business concern.
(b) The method of costing should be suitable to the industry.
(c) Necessary co-operation and participation of executives from various departments
of the concern is essential for developing good cost accounting system.
(d) The cost of installing and operating the system should justify the results.
(e) The system of costing should not sacrifice the utility by introducing meticulous and
unnecessary details.

Question 6
Distinguish between the following?
Controllable costs and uncontrollable costs.

Answer
Controllable costs and uncontrollable costs:
Costs which can be influenced by the action of a specified person in an organisation are
known as controllable costs. Costs which remains unaffected by the action of such person
are termed as uncontrollable. In a business organisation heads of each responsibility
centre are responsible to control costs. Costs which they are able to control are known as
controllable and includes material, labour and direct expenses. Costs which they fail to
control includes fixed costs and all allocated costs.
It may be noted that controllable and uncontrollable cost concepts are related to the
authority of a person in the organisation. An expenditure which may be uncontrollable
by one person may be controllable by another. Moreover, in the long run all costs might
be controllable.

Question 7
(a) Describe briefly the role of the cost accountant in a manufacturing organisation.
(b) Distinguish between:
(i) Variable cost and direct cost
(ii) Estimated cost and standard cost.

Answer
(a) Cost accountant in a manufacturing organisation plays several important roles.
He establishes a Cost Accounting department in his concern. He ascertains the
equirement of cost information which may be useful to organisational mangers at
different levels of the hierarchy. He develops a manual, which specifies the functions
to be performed by the Cost Accounting department. The manual also contains the
format of various forms which would be utilised by the concern for procuring and
providing information to the concerned officers. It also specifies the frequency at
which the cost information would be supplied to a concerned executive.
Usually, the functions performed by a Cost Accounting department includes cost
ascertainment, cost comparison, cost reduction, cost control and cost reporting.
Cost ascertainment, requires the classification of costs into direct and indirect.
Further it requires classification of indirect costs (known as overheads) into three

17
 INTER CA. – COSTING

classes viz, factory overheads; administration overheads and selling and distribution
overhead. Cost accountant suggests the basis which may be used by his subordinates
for carrying out the necessary classifications as suggested above.
Cost comparison is the task carried out by Cost Accountant for controlling the
cost of the products manufactured by the concern. Cost Accountant of the concern
establishes standards for all the elements of cost and thus a standard cost of the
finished product. The standard cost so determined may be compared with the actual
cost to determine the variances. Cost Accountant ascertains the reasons for the
occurrence of these variances for taking suitable action.
Cost analysis may also be made by Cost Accountant for taking decisions like make
or by and for reviewing the current performance.
Cost Accountant also suggests suitable techniques for the purpose of cost reduction
/ cost control, after carrying out a cost benefit analysis.
Cost Accountant also plays a key role in the preparation of Cost reports. These
reports help the executives of a business concern in reviewing their own performance
and in identifying the weak areas, where enough control measure may be taken in
future.
In brief, one may say that there is hardly any activity in a manufacturing organisation
with which a Cost Accountant is not directly associated in some form or the other.
(b) (i) Variable and direct cost: A variable cost is a cost that changes in total in direct
proportion to changes in the related total activity or volume. Cost of material
is an example of variable cost.
Direct cost is a cost which can be identified either with a cost centre or with a
cost unit. An example of direct cost is the allocation of direct materials to a
department and then to the various jobs. All variable costs are direct-but each
direct cost may not be variable.
(ii) Estimated cost and standard cost: Kohler defines estimated costs as ‘the expected
cost of manufacture or acquisition, often in terms of a unit of product computed
on the basis of information available in advance of actual production or
purchase’ Estimated cost are prospective costs since they refer to prediction of
costs.
Standard Cost means a pre-determined cost. It attempts to show what the
cost should be for clearly defined conditions and circumstances. Standard costs
represent’ planned cost of a product. They are expected to be achieved under a
particular production process under normal conditions.
Although pre-determination is the essence of both standard costs and estimated

18

costs, but they differ from each other in the following respects:
(i) Difference in computation (iv) Difference in records
(ii) Difference in emphasis (v) Applicability
(iii) Difference in use

Question 8
Enumerate the main objectives of introduction of a Cost Accounting System in a
manufacturing organisation.  (Nov., 2002, 3 Marks)

Answer
The main objectives of introduction of a Cost Accounting System in a manufacturing
organization are as follows:
(i) Ascertainment of cost
(ii) Determination of selling price
(iii) Cost control and cost reduction
(iv) Ascertainment of profit of each activity
(v) Assisting in managerial decision making

Question 9
Write short notes on the following?
(i) Conversion cost
(ii) Sunk cost
(iii) Opportunity cost
Answer
(i) Conversion cost: It is the cost incurred to convert raw materials into finished goods. It
is the sum of direct wages, direct expenses and manufacturing overheads.
(ii) Sunk cost: Historical costs or the costs incurred in the past are known as sunk cost.
They play no role in the current decision making process and are termed as irrelevant
costs. For example, in the case of a decision relating to the replacement of a machine,
the written down value of the existing machine is a sunk cost, and therefore, not
considered.
(iii) Opportunity cost: It refers to the value of sacrifice made or benefit of opportunity
foregone in accepting an alternative course of action. For example, a firm financing
its expansion plan by withdrawing money from its bank deposits. In such a case
the loss of interest on the bank deposit is the opportunity cost for carrying out the
expansion plan.

Question 10
How does a production account differ from a cost sheet?  (May, 2000, 3 Marks)

Answer
The following are the points of difference between a production account and a cost sheet.
(i) Production Account is based on double entry system whereas cost sheet is not based
on double entry system.
(ii) Production Account consists of two parts. The first part shows cost of the component
and total production cost. The second part shows the cost of sales and profit for the
period. Cost Sheet presents the elements of costs in a classified manner and the cost
ascertained at different states such as prime cost; works cost; cost of production;
cost of goods sold; cost of sales and total cost.
(iii) Production Account shows the cost in aggregate and thus facilitates comparison
with other financial accounts. Cost sheet shows the cost in a detailed and analytical
manner which facilitates comparison of cost for the purpose of cost control.
(iv) Production Account is not useful for preparing tenders or quotations. Estimated cost
sheets can be prepared on the basis of actual cost sheets and these are useful for
preparing tenders or quotations.

Question 11
Discuss cost classification based on variability and controllability.
 (Nov. 2004, 4 Marks)
Answer
Cost classification based on variability
Fixed cost – These are costs, which do not change in total despite changes of a cost driver.
A fixed cost is fixed only in relation to a given relevant range of the cost driver and a given
time span. Rent, insurance, depreciation of factory building and equipment are examples
of fixed costs where the final product produced is the cost object.
Variable costs – These are costs which change in total in proportion to changes of cost
driver. Direct material, direct labour are examples of variable costs, in cases where the
final product produced is the cost object.
Semi-variable costs – These are partly fixed and partly variable in relation to output e.g.
telephone and electricity bill.
Cost classification based on controllability
Controllable costs – Are incurred in a particular responsibility center and relate to a
defined time span. They can be influenced by the action of the executive heading the

20
 INTER CA. – COSTING

responsibility center e.g. direct costs.

Uncontrollable costs – Are costs are influenced by the action of the responsibility center
manager e.g. expenditure incurred by the tool room are controllable by the foreman in
charge of that section, but the share of tool room expenditure which are apportioned to
the machine shop are not controllable by machine shop foreman.

Question 12
Discuss the essential of a good cost accounting system?  (May 2004, 2 Marks)

Answer
Essentials of a good cost accounting system:
• It should be tailor-made, practical, simple and capable of meeting the requirements
of a business concern.
• The data used by the system should be accurate, otherwise it may distort the output
of system.
• Cost of installing & operating the system should justify the results.
• Cost accounting system should have the support of top management of the concern.
• The system should have the necessary support from all the user’s departments.

Question 13
Explain:
(i) Sunk Costs
(ii) Pre-production Costs
(iii) Research and Development Costs
(iv) Training Costs  (Nov., 2000, 2 x 4 = 8 Marks)

Answer
(i) Sunk Costs: These are historical costs which are incurred in the past. These costs were
incurred for a decision made in the past and cannot be changed by any decision that
will be made in future. In other words, these costs plays no role in decision making,
in the current period. While considering the replacement of a plant, the depreciated
book value of the old plant is irrelevant, as the amount is a sunk cost which is to be
written off at the time of replacement.
(ii) Pre-production Costs: These costs forms the part of development cost, incurred in
making a trial production run, preliminary to formal production. These costs are
incurred when a new factory is in the process of establishment or a new project is

21
 INTER CA. – COSTING

undertaken or a new product line or product is taken up, but there is no established
or formal production to which such costs may be charged. These costs are normally
treated as deferred revenue expenditure (except the portion which has been
capitalised) and charged to the costs of future production.
(iii) Research and Development Costs: Research costs are the costs incurred for the discovery
of new ideas or processes by experiment or otherwise and for using the results
of such experimentation on a commercial basis. Research costs are defined as the
costs of searching for new or improved products, new applications of materials, or
improved methods, processes, systems or services.
Development costs, are the costs of the process which begins with the
implementation of the decision to produce a new or improved product or to employ
a new or improved method and ends with the commencement of formal production
of that product by that method.
(iv) Training Costs: These costs comprises of – wages and salaries of the trainees or
learners, pay and allowances of the training and teaching staff, payment of fees etc.,
for training or for attending courses of studies sponsored by outside agencies and
cost of materials, tools and equipments used for training. Costs incurred for running
the training department, the losses arising due to the initial lower production, extra
spoilage etc. occurring while providing training facilities to the new recruits.
All these costs are booked under separate standing order numbers for the various
functions. Usually there is a service cost centre, known as the Training Section,
to which all the training costs are allocated. The total cost of training section is
thereafter apportioned to production centers.

Question 14
Enumerate the factors which are to be considered before installing a system of cost
accounting in a manufacturing organization.

Answer
Factors which are to be considered before installing a system of cost accounting in a
manufacturing organization are:
(i) The objectives of installing a system of cost accounting should be defined, that is
whether the system is meant for control of cost or for price fixation.
(ii) The organization of the company should be studied to understand the authority and
responsibilities of the managers.
(iii) The technical aspects and flow process should be taken into consideration.

22
 INTER CA. – COSTING

(iv) The products to be manufactured should be studied.

(v) The marketing set up to be looked into for devising suitable control reports.
(vi) The possibility of integrating cost accounting system with financial accounting
system should be examined.
(vii) The procedure for collection and verification of reliability of the information should
be studied.
(viii) The degree of details of information required at each level of management should
be examined.
(ix) The maximum amount of information that would be sufficient and how the same
should be secured without too much clerical labour, especially the possibility of
collection of data on a separate printed form designed for each process; also the
possibility of instruction as regards filling up of the forms in writing to ensure that
these would be faithfully carried out.
(x) How the accuracy of the data collected can be verified? Who should be made
responsible for making such verification with regard to each operation and the form
of certification that should be given indicate verification that he has carried out.
(xi) The manner in which the benefits of introducing Cost Accounting could be explained
to various persons in the concern, especially those incharge of production department
and an awareness created for the necessity of promptitude, frequency and regularity
in collection of costing data.

Question 15
You have been asked to install a costing system in a manufacturing company. What
practical difficulties will you expect and how will you propose to overcome the same?
 (May 2004, 4 Marks)
Answer
The practical difficulties with which a Cost Accountant is usually confronted with while
installing a costing system in a manufacturing company are as follows:
(i) Lack of top management support: Installation of a costing system do not receive the
support of top management. They consider it as an interference in their work. They
believe that such, a system will involve additional paperwork. They also have a
mis-concept in their minds that the system is meant for keeping a check on their
activities.

(ii) Resistance from cost accounting departmental staff: The staff resists because of fear of
loosing their jobs and importance after the implementation of the new system.

23
 INTER CA. – COSTING

(iii) Non - cooperation from user departments: The foremen, supervisor and other staff
members may not cooperate in providing requisite data, as this would not only add
to their responsibilities but will also increase paper work of the entire team as well.
(iv) Shortage of trained staff: Since cost accounting system’s installation involves
specialised work, there may be a shortage of trained staff.
To overcome these practical difficulties, necessary steps required are :
* To sell the idea to top management – To convince them of the utility of the
system.
* Resistance and non-cooperation can be overcome by behavioural approach. To
deal with the staff concerned effectively.
* Proper training should be given to the staff at each level.
* Regular meetings should be held with the cost accounting staff, user
departments, staff and top management to clarify their doubts / misgivings.

Question 16
Define Explicit costs. How is it different from implicit costs?  (May, 2001, 2 Marks)

Answer
Explicit costs: These costs are also known as out of pocket costs. They refer to those
costs which involves immediate payment of cash. Salaries, wages, postage and telegram,
interest on loan etc. are some examples of explicit costs because they involve immediate
cash payment. These payments are recorded in the books of account and can be easily
measured.
Main points of difference: The following are the main points of difference between explicit
and implicit costs.
(i) Implicit costs do not involve any immediate cash payment. As such they are also
known as imputed costs or economic costs.
(ii) Implicit costs are not recorded in the books of account but yet, they are important for
certain types of managerial decisions such as equipment replacement and relative
profitability of two alternative courses of action.

Question 17
What are the main objectives of Cost Accounting?  (May 2001, 2 Marks)

24
 INTER CA. – COSTING

Answer
The main objectives of Cost Accounting are as follows:
(i) Ascertainment of cost.
(ii) Determination of selling price.
(iii) Cost control and cost reduction.
(iv) Ascertainment of profit of each activity.
(v) Assisting management in decision making.

Question 18
Explain controllable and non-controllable costs with illustrations.  (May 2001, 2 Marks)

Answer
Controllable and non-Controllable costs
Controllable costs: These are the costs which can be influenced by the action of a specified
person in an organisation. In every organisation, there are a number of departments
which are called responsibility centres, each under the charge of a specified level of
management. Costs incurred in these responsibility centres are influenced by he action of
the incharge of the responsibility centre. Thus any cost that an organisational unit has
the authority to incur may be identified as controllable cost.
Non-controllable costs: These are the costs which cannot be influenced by the action of
a specified member of an undertaking. For example, expenditure incurred by the ‘Tool
Room’ is controllable by the Tool Room Manager but the share of Tool Room expenditure,
which is apportioned to the Machine Shop cannot be controlled by the manager of the
Machine Shop.
However, the distinction between controllable and non-controllable costs is not very
sharp and is sometimes left to individual judgment to specify a cost as controllable or
non-controllable in relation to a particular individual manager.

Question 19
Discuss the four different methods of costing alongwith their applicability to concerned
industry?  (Nov. 1999, 4 Marks)

Answer
Four different methods of costing along with their applicability to concerned industry
have been discussed as below:
1. Job Costing: The objective under this method of costing is to ascertain the cost of

25
 INTER CA. – COSTING

each job order. A job card is prepared for each job to accumulate costs. The cost of
the job is determined by adding all costs against the job it is incurred. This method
of costing is used in printing press, foundries and general engineering workshops,
advertising etc.
2. Batch Costing: This system of costing is used where small components / parts of the
same kind are required to be manufactured in large quantities. Here batch of similar
products is treated as a job and cost of such a job is ascertained as discussed under
1, above. If in a cycle manufacturing unit, rims are produced in batches of 2,500
units each, then the cost will be determined in relation to a batch of 2,500 units.
3. Contract Costing: If a job is very big and takes a long time for its completion, then
method used for costing is known as Contract Costing. Here the cost of each contract
is ascertained separately. It is suitable for firms engaged in the construction of
bridges, roads, buildings etc.
4. Operating Costing: The method of Costing used in service rendering undertakings is
known as operating costing. This method of costing is used in undertakings like
transport, supply of water, telephone services, hospitals, nursing homes etc.

Question 20
How would you deal the following items in the cost accounts of a manufacturing concern?
(a) Research and Development cost
(b) Packing Expenses
(c) Fringe Benefits
(d) Expenses on Removal and Re-erection of Machinery.

Answer
(a) Research and Development Cost: Research and Development Cost is the cost / expense
incurred for searching new or improved products, production method / techniques
or plants/ equipments. Research Cost may be incurred for carrying basic or applied
research. Both basic and applied research relates to original investigation to gain
from new scientific or technical knowledge and understanding, which is not directed
towards any specific practical aim (under basic research) and is directed towards a
specific practical aim or objective (under applied research).
Treatment in Cost Accounts
Cost of Basic Research (if it is a continuous activity) be charged to the revenues of
the concern. It may be spread over a number of years if research is not a continuous
activity and amount is large.

26
 INTER CA. – COSTING

Cost of applied research, if it relates to all existing products and methods of

production then it should be treated as a manufacturing overhead of the period
during which it has been incurred and absorbed. Such costs are directly charged to
the product, if it is solely incurred for it.
If applied research is conducted for searching new products or methods of production
etc., then the research costs treatment depends upon the outcome of such research.
For example. If research findings are expected to produce future benefits or if it
appears that such findings are going to result in failure then the costs incurred may
be a mortised by charging to the Costing Profit and Loss Accounts of one or more
years depending upon the size of expenditure. If research proves successful, then
such costs should be charged to the concerned product.
Development Costs, begins with the implementation of the decision to produce a
new or improved product or to employ a new or improved method. The treatment of
development expenses is same as that of applied research.
(b) Packing Expenses: It includes the expenses incurred on wrapping, tying,
bottles, boxes, containers or bags etc. In Cost Accounts they are treated as
follows:
(i) It is treated as a direct material cost in the case of those products which cannot
be sold without the use of a packing. For example ink-pot; Bread; paste etc.
(ii) It may be treated as distribution overhead if packing expenses are incurred to
facilitate the transportation of finished products.
(iii) It may be treated as advertisement cost and included in selling overheads if it
is incurred for advertisement to make the product attractive.
(c) Fringe Benefits: Additional Benefits paid to the employees of a concern and are
not related to the direct efforts of the employees, are called fringe benefits. They
include holiday pay; leave pay; employer’s contribution to provident fund; gratuity
and pension schemes; state insurance; medical benefits; subsidised facility etc.
Expenditure incurred on fringe benefits in the case of factory workers should be
treated as factory overheads and are apportioned among all the production and
service departments on the basis of the number of workers in each department.
Fringe benefits to office and selling and distribution staff should be treated as
administration and selling and distribution overheads respectively and are recovered
accordingly.
(d) Expenses on Removal and Re- erection of Machinery: Expenses are sometime
incurred on removal and re-erection of machinery in factories. Such expenses may
be incurred due to factors like change in the method of production; an addition or

27
 INTER CA. – COSTING

alteration in the factory building, change in the follow of production, etc. All such
expenses are treated as production overheads. When amount of such expenses is
large, it may be spread over a period of time.
If such expenses are incurred due to faulty planning or some other abnormal factor,
then they may be charged to Costing Profit and Loss Account.

Question 21
Define administration overheads and state briefly the treatment of such overheads in
Cost Accounts.  (Nov. 1996, 4 Marks)

Answer
Definition of Administration Overhead: These are costs of formulating the policy, directing
the organisation and controlling the operation of an undertaking. These are not related
directly to production activity or function. In other words, all expenses, incurred on policy
formulation, direction, control, office administration and business management are
included in administration overheads.
Treatment of Administrative Overheads in Cost Accounting:
(i) Charge to Costing Profit and Loss Account: According to this method administrative
overheads should be treated as fixed cost as they are concerned with the formulation
of policy. Hence these overheads should be transferred to the Costing Profit and Loss
Account.
(ii) Apportionment between Production and Selling and Distribution: According to this method,
it is assumed that administrative overheads are incurred both for production and
for selling and distribution. Therefore these overheads should be divided on some
equitable basis between production and selling and distribution activity.
(iii) Treat as a separate element of total cost: Here administration overheads are considered
as a cost of a distinct and identifiable operation of the organisation necessary to
carry on its activity. Therefore these overheads are recovered separately on some
equitable basis which may be on cost or sales basis.

Question 22
Enumerate the arguments for the inclusion of interest on capital in cost accounts.

Answer
Arguments for the inclusion of interest on capital in cost accounts :
1. Interest is the cost of capital as wages are the reward for labour. Both are factors of

28
 INTER CA. – COSTING

production and, therefore should not be treated differently in cost accounts. While
determining the total cost, interest like wages should also be included in the cost of
production.
2. The exclusion of interest from cost accounts, particularly in businesses where raw
material is used in different states of readiness would distort costs and render their
comparison a difficult one.
3. Profit on different jobs/ operations requiring different periods for completion may
not be comparable if interest on capital is not included in their total cost,
4. Sometime exclusion of interest cost may lead the management to take wrong
decisions.
5. The significance of time value of money is recognized only when interest is treated
as an element of cost.

Question 23
What is notional rent of a factory building? Give one reason why it may be included in
cost accounts.  (November 1995, 2 Marks)

Answer
Notional Rent: It is a reasonable charge raised in the cost accounts for the use of owned
premises. One reason for the use of such a nominal charge is to enable comparison
between the cost of items made in factories which are owned and in rented factories.
However, it may be noted that in the case of owned factory, cost for the same is accounted
for by means of depreciation.

Question 24
How do you deal with the following in cost accounts?
Bad debts. (November 1999, 4 Marks)

Answer
Treatment of Cost Accounts
Bad debts: There is no unanimity among various authors about the treatment of bad
debts. Some authors believe that bad debts are financial losses and therefore should
not be included in the cost of a particular product or job. Another view is that, bad debts
are a part of selling and distribution overhead, especially where they arise in the normal
course of trading. Therefore they should be treated in cost accounts in the same way as
any other selling and distribution expense.

29
 INTER CA. – COSTING

Question 25
How would you treat the following in Cost Accounts?
(i) Employee welfare costs  (2 Marks)
(ii) Research and development costs  (2 Marks)
(iii) Depreciation (May, 1996)  (2 Marks)

Answer
(i) Employee Welfare Costs: It includes those expenses, which are incurred by the
employers on the welfare activities of their employees. The welfare activities on
which these expenses are usually incurred may include canteen, hospital, play
grounds, etc. These expenses should be separately recorded as Welfare Department
Costs. These Costs may be apportioned to production cost centres on the basis of
total wages or the number of men employed by them.
(ii) Research and development costs: It is the cost/expense incurred for searching new
or improved products, production methods/techniques or plants/equipments. Re–
search cost may be incurred-for carrying basic or applied research. Both basic and
applied research relates to original investigations to gain from new scientific or
technical knowledge and understanding, which is not directed towards any specific
practical aim (under basic research) and is directed towards a specific practical aim
or objective (under applied research).
Treatment in Cost Accounts: Cost of Basic Research (if it is a continuous activity) be
charged to the revenues of the concern. It may be spread over a number of years if
research is not a continuous activity and amount is large.
Cost of applied research, if relates-to all existing products and methods of production
then it should be treated as a manufacturing overhead of the period during which it
has been incurred and absorbed. Such costs are directly charged to the product, it is
solely incurred for it.
If applied research is conducted for searching new products or methods of production
etc. then the research costs treatment depends upon the outcome of such research.
For example, if research findings are expected to produce future benefits or if it
appears that such findings are going to result in failure then the costs incurred may
be amortised by charging to the Costing Profit and Loss Account of one or more
years depending upon the size of expenditure. If research proves successful, then
such costs will be charged to the concerned product.
Development Costs begins with the implementation of the decision to produce a
new or improved product or to employ a new or improved method. The treatment of

30
 INTER CA. – COSTING

development expenses is same as that of applied research.

(iii) Depreciation: It represents the fall in the asset value due to its use, wear and tear
and passage of time. Depreciation is an indirect cost of production and operations.
It is an important element of cost and without this true cost of production cannot
be obtained. In costing; depreciation on plant and machinery is normally treated as
part of the factory overheads.

Question 26
Discuss the treatment in cost accounts of the cost of small tools of short effective life.
 (May 2002, 4 Marks)
Answer
Small tools are mechanical appliances used for various operations on a work place,
specially in engineering industries. Such tools include drill bits, chisels, screw cutter, files
etc.
Treatment of cost of small tools of short effective life:
(i) Small tools purchased may be capitalized and depreciated over life if their life is
ascertainable. Revaluation method of depreciation may be used in respect of very
small tools of short effective life. Depreciation of small tools may be charged to :
– Factory overheads
– Overheads of the department using the small tool.
(ii) Cost of small tools should be charged fully to the departments to which they have
been issued, if their life is not ascertainable.

Question 27
Define Product costs. Describe three different purposes for computing product costs.

Answer
Definition of product costs:
Product costs are inventoriable costs. These are the costs, which are assigned to the
product. Under marginal costing variable manufacturing costs and under absorption
costing, total manufacturing costs constitute product costs.
Purposes for computing product costs:
The three different purposes for computing product costs are as follows:
(i) Preparation of financial statements: Here focus is on inventoriable costs.
(ii) Product pricing: It is an important purpose for which product costs are used. For this
purpose, the cost of the areas along with the value chain should be included to

31
 INTER CA. – COSTING

make the product available to the customer.

(iii) Contracting with government agencies: For this purpose government agencies may
not allow the contractors to recover research and development and marketing costs
under cost plus contracts.
rease tariff, increase in the prices of consumables etc.

 INTER CA. – COSTING

ABSORPTION COSTING &

OVERHEADS

THEORY SECTION

ABSORPTION COSTING

1. GENERAL:
In order to get fixed overheads cost per unit, for the purpose of determining the
sales price, we need to know the actual fixed overheads and actual level of activity;
But the actual overheads and the actual level of activity would be known to us only
at the end of the accounting year, whereas the sales price has to be known before
the commencement of the accounting year and therefore the actual information
cannot be used.
Absorption costing technique as against marginal costing technique, lays down
artificial link between the budgeted overheads and the budgeted level of activity, to
get budgeted overheads charge, which is known as "Absorption rate, recovery rate or
application rate.
The level of activity can be expressed in terms of output, machine hours, labour
hours, labour cost, material cost or prime cost, man-days etc.
Once the absorption rate is developed, every time something is produced, the
overheads will be charged at absorption rate. Thus, the factory overheads that we
write in the cost sheet are absorbed overheads and not the actual. (Unless the
company follows marginal costing).

33
 INTER CA. – COSTING

2. METHODS:
Depending on the terms in which level of activity is expressed, there are six different
methods; as stated below:

(a) Output method = ` - Per Unit

(b) Machine hour rate = ` - Per Machine Hour

(c) Labour hour rate = ` - Per Labour Hour

(d) Labour cost method x 100 = % of Labour Cost

(e) Material Cost Method x 100 = % of Material Cost

(f) Prime cost method x 100 = % of Prime Cost

34
 INTER CA. – COSTING

3. Selection of Method:
(a) If the company manufactures only one product, or two or more products but
which are more or less identical from overheads point of view, then the output
method is the best.
(b) When the company manufactures two or more products which are quite different
from overheads point of view.
(i) Machine hour rate:
If the production is basically machine oriented, then the overheads would
mainly depend on machine utilisation and therefore the product which will
make more use of machines, should be charged more amount of overhead
also. Accordingly, we follow machine hour rate method.
(ii) Labour hour rate / labour cost method:
When the output is predominately labour oriented, we may follow one of
these two methods.
If the overheads mainly depend on labour time, then, the labour hour
rate method should be followed whereas, if the overheads mainly depend
upon labour type, then labour cost method should be followed. If may
be noted that if there is only one of labour, or there are different types of
labour but the wage are same, these two methods will give identical results.
(iii)
Material cost method:
If the overheads depend on the cost of raw material consumed, then this
method should be followed.
(iv)
Prime cost method:
If he overheads depend on not only the material cost but also on the
labour cost, we follow this method.

4. Detection of Method:
Sometimes, the method is neither named nor adequate information is given so as to
enable us to calculate the rate. However, overheads absorbed in the past months
of the same accounting period are given alongwith level of activity in different
terms. In such cases, we compare the overheads absorbed with level of activity in
different terms and whichever method gives consistently the same rate of overheads
absorption can be presumed as being followed by the company. If two or more
methods satisfy this condition, any of them can be selected at random. If the method
is named but the rates are not given, then, in such cases also, the same technique
can be followed to detect the rates.

35
 INTER CA. – COSTING

5. Under / Over Absorption of Overheads:

At the end of the accounting year we compare actual fixed overheads with fixed
overheads absorbed difference is known as under / over absorption of overhead.
Under or over absorption will arise whenever either overheads will change or output
will change or both will change but not in same proportion. If both will change in
same proportion then there will not be any under or over absorption of overheads.

6. Treatment of under / over absorption of overheads:

1. Carry Forward Method
Under this method under / over absorbed amount is carried forward to next
year. This method is not allowed in financial accounting because in financial
accounting expenses of current year cannot be carried forward to next year.
2. Adjust in Current Year
(A) Adjust in cost of sales / Costing P & L A/c at the end of the year
In this method under / over absorbed amount is to be adjusted in cost of
Sales or Costing P & L A/c.

36
 INTER CA. – COSTING

In this method under / over absorbed amount is charged to Sales Quantity

instead of Production Quantity.

(B) Supplementary Rate Method

In this method under or over absorbed amount is to be adjusted at the
same place where absorbed amount is recorded.
In this method under or over absorbed amount is charged to Production
Quantity.
Supplementary rate method can be followed during the year or at the end
of the year.

1. Objective: It is to get total budgeted overheads, the ultimate objective being to get
the overhead absorption rate so that the overhead can be charged to the output for
preparing the cost sheet. The Budgeted level of activity in this chapter would always
be given. The technique is also to be used to get actual overheads at the end of the
year.

2. Types of Departments: There can be two types of departments in all, namely,

production department and service department, The production departments
are in charge of production and therefore they incur the prime cost as well as the
overhead. Whereas the service departments manufacture nothing but only render
some very useful and vital service to the production departments. Accordingly every
conceivable expenditure, by whatever name called, that the service departments
(e.g. canteen department) incur is always an overhead expenses item.

3. Type of Overheads Expenses: There are following three types of expenses in all.
(A) Primary distribution:
(i) Allocable overheads
(ii) Apportionable overheads
(B) Secondary distribution:
(iii) Reapportionable overheads of service departments,

The allocable expenses are the expenses for which various depts. can be directly
held responsible and therefore we directly charge expenses to those departments.

The apportionable overheads are common expenses (e.g. rent) for which no
department can be directly held responsible. We apportion these expenses to
various departments on some equitable basis, the basis being the one on which
the expenditures basically depends (e.g. Rent basically would depend on area and
therefore we apportion it on the basis of area occupied. If area is not given then
we settle for the next best option. (no. of light points). If that also is not given then
we prefer still next best (may be number of employees) and if we have no other
alternative now, then we go to the last resort. If the production is basically machine
oriented then, such expenses we apportion in the ratio of machine hours and if
labour oriented then on the basis of labour hours or direct labour cost.

38
 INTER CA. – COSTING

Re-apportionable expenses are the total expenses of service departments (allocated

and apportioned), They are now to be reapportioned, effectively, to production
departments. There are 3 possibilities in all as shown below, but it should be
obvious that the reapportionment has to be in the ratio of service rendered. It is to
be reapportioned to all those departments which have taken the service.
(i) Totally independent service departments: (Direct Method) In such cases the order
in which we take up the service departments is not important. because the
expenses are to be reapportioned only the production departments. Here all
service departments render service only to production departments.

(ii) Partially dependent service departments: (or Step, ladder method) Here one
service department renders the service to the other of them but, does not take
the service of other of them. Accordingly, the order in which we take up the
department is very important.

(iii) Totally interdependent service departments: (Reciprocal Method) Here each service
department renders the service to other of them and takes the service from
other of them also. There are two methods in all and any of which can be
employed, the result remaining to same.
(a) Continuous distribution or cycle method.
(b) Equation method.

IMPORTANT THEORY QUESTIONS FOR EXAMINATION

Question 1
What is an idle capacity? What are the costs associated with it? How are these treated in
product costs?
Answer
Idle Capacity: Idle capacity is that part of the capacity of a plant, machine or equipment
which cannot be effectively utilised in production. In other words, it is the difference
between the practical or normal capacity and capacity of utilisation based on expected
sales. For example, if the practical capacity of production of a machine is to the tune
of 10,000 units in a month, but is used only to produce 8,000 units, because of market
demand of the product, then in such a case, 2,000 units will be treated as the idle
capacity of the machine.

The idle capacity may arise due to lack of product demand, non-availability of raw-
material, shortage of skilled labour, absenteeism, shortage of power, fuel or supplies,
seasonal nature of product, etc.

Idle Capacity Costs: Costs associated with idle capacity are mostly fixed in nature. These
include depreciation, repairs and maintenance charges, insurance premium, rent, rates,
management and supervisory costs. These costs remain unabsorbed or unrecovered due
to under-utilisation of plant and service capacity. Idle capacity cost can be calculated as
follows:
Idle capacity cost = × Idle Capacity
Treatment of Idle capacity cost: Idle capacity costs can be treated in product costing, in
the following ways :
(i) If the idle capacity cost is due to unavoidable reasons such as repairs, maintenance,
changeover of job, etc., a supplementary overhead rate may be used to recover the
idle capacity cost. In this case, the costs are charged to the production capacity
utilised.
(ii) If the idle capacity cost is due to avoidable reasons such as faulty planning, power
failure etc., the cost should be charged to profit and loss account.
(iii) If the idle capacity cost is due to seasonal factors, then, the cost should be charged
to the cost of production by inflating overhead rates.

Question 2
Describe job Costing and Batch Costing giving example of industries where these are
used? (May 2001, 3 Marks)
Answer
Job Costing: It is a method of costing which is used when the work is undertaken as
per the customer’s special requirement. When an inquiry is received from the customer,
costs expected to be incurred on the job are estimated and on the basis of this estimate,
a price is quoted to the customer. Actual cost of materials, labour and overheads are
accumulated and on the completion of job, these actual costs are compared with the
quoted price and thus the profit or loss on it is determined.

Job costing is applicable in printing press, hardware, ship-building, heavy machinery,

foundry, general engineering works, machine tools, interior decoration, repairs and other
similar work.

Batch Costing: It is a variant of job costing. Under batch costing, a lot of similar units
which comprises the batch may be used as a unit for ascertaining cost. In the case of batch
costing separate cost sheets are maintained for each batch of products by assigning a
batch number. Cost per unit in a batch is ascertained by dividing the total cost of a batch
by the number of units produced in that batch.
Such a method of costing is used in the case of pharmaceutical or drug industries, ready-
made garment industries, industries, manufacturing electronic parts of T.V. radio sets etc.

Question 3
Distinguish between Job Costing & Batch Costing?
(Nov. 2004, Nov. 2006, 2 Marks)
Answer
Job Costing and Batch Costing
Accounting to job costing, costs are collected and accumulated according to job. Each
job or unit of production is treated as a separate entity for the purpose of costing. Job
costing may be employed when jobs are executed for different customers according to
their specification.
Batch costing is a form of job costing, a lot of similar units which comprises the batch
may be used as a cost unit for ascertaining cost. Such a method of costing is used in case
of pharmaceutical industry, ready-made garments, industries manufacturing parts of TV,
radio sets etc.

COST ACCOUNTING SYSTEM

THEORY SECTION
INTEGRAL & NON – INTEGRAL ACCOUNTS

(I) GENERAL - Under integral accounting system, only one set of books of accounts is
prepared and the accounts are written in such a manner that due justice is done
to all the Cost Accounting and financial Accounting principles. The accounts to be
opened would depend on ultimate outcome expected and ultimate outcome of
integral accounting system is the cost sheet for cost accountant and profit and loss
A/c and balance sheet for financial accountant.
Under non-integral accounting system, two different sets of books are maintained,
one for financial and other for cost accounting purposes. Since we are concerned only
with cost accounting under this system, in the problem on non-integral accounting,
we only need to know how the accounts are to be written for cost accounting
purposes.

(II) NON-INTEGRAL ACCOUNTING SYSTEM :

(1) Necessary accounts to be opened:
(a) GENERAL LEDGER ADJUSTMENT A/C OR COST LEDGER CONTROL A/C:
This is practically a dummy A/c and is to be used where one of the two
parts of the journal is a cost sheet item and the other is a Balance Sheet
item. Since Balance Sheet items have no place in our system, the Balance
Sheet part of the Journal, whether debit or credit, is to be replaced by this
account. If both the parts of the journal are balance sheet items or both
the parts are cost sheet items, then naturally this account has no use.
(b) STORES LEDGER CONTROL A/C.
This is in respect of raw material when raw material is purchased, this
account is debited and when raw material is issued to the production
department, it is credited to this a/c and debited to Work-in-progress a/c.
The material issued for repairs and maintenance is also credited to this

63
 INTER CA. – COSTING

account and debited to factory overheads account. Likewise, abnormal

loss of material is credited to this account and debited to costing profit
and loss A/c.
(c) WORK-IN-PROGRESS LEDGER CONTROL A/C:
On the debit side of this A/c, we write opening balance and factory cost
incurred. On the credit side, factory cost of production completed is
transferred to finished goods ledger control a/c and balance is closing
stock. Also, if there is some abnormal loss, the factory cost of abnormal
loss (Prime cost and Factory overheads) is credited to this A/c and debited
to abnormal loss A/c and similarly, abnormal gain is debited to this a/c
and credited to abnormal gain a/c.
(d) FINISHED GOODS LEDGER CONTROL A/C:
On the debit side of this A/c, we write opening stock of finished goods,
factory cost of production completed and transferred to warehouse and
administration overheads. On the credit side, the production cost of goods
sold is transferred to cost of sales a/c and the balance is closing stock of
finished goods.
(e) WAGE CONTROL A/C:
On the debit side of this a/c, we write the wages incurred, whether
direct or indirect. On the credit side, the indirect wages could be factory,
administration or S & D overheads and depending on that, we transfer
them to Factory overheads Control A/c, administration Overheads Control
A/c or S & D overheads Control A/c. Direct wages are transferred to Work-
in-progress account. It is also possible (in fact, better) to transfer to this
account, only direct wages and to transfer indirect wages directly from
GLA A/c to respective overheads accounts.
(f) Factory overheads Control A/c.
(g) Administrative Overheads Control A/c.
(h) Selling and Distribution overheads Control A/c.
On the Debit side of each of these accounts, we write the amount actually
spent.
The factory overheads, to the extent recovered, are transferred to Work-
in-progress Ledger Control A/c. The administrative overheads are similarly
transferred to Finished Goods ledger control A/c and S & D Overheads are
transferred to cost of sales a/c.
As regards the difference between the amount spent and recovered,

64
 INTER CA. – COSTING

if there is some instruction, direct or indirect, it should be followed. In

the absence thereof, there are two alternatives. One is to transfer the
difference to Costing Profit & Loss A/c and the other is to carry it forward
by showing the difference as closing balance. It is also possible to follow
supplementary rate system.
If opening trail balance is given and such items do appear in it then that
means the company follows the policy of carrying forward the difference
to the next period. If they do not appear in the opening trial balance
then, in the absence of information to the contrary, these A/c's should be
closed by transferring the difference to Costing Profit & Loss A/c. If the
supplementary system is to be followed, then, the difference should be
transferred to the same account to which absorption is transfered.
(i) COST OF SALES A/C:
On the debit side of this A/c, we write production cost of goods sold (which
is transferred from finished goods ledger control a/c) and Selling and
Distribution overheads. The total being cost of sales, we transfer it to
Costing Profit and Loss A/c.
(j) SALES A/C:
On the credit side of this a/c, we write the amount of sales by debiting
General ledger Adjustment A/c and we close this A/c by transferring sales
to costing Profit and Loss A/c.
(k) ABNORMAL LOSS / GAIN A/C:
These are the a/c's for recording the transactions of abnormal nature and
we close these a/c's by transferring the balance to profit and Loss A/c.
(1) COSTING PROFIT AND LOSS A/C:
On the debit side of this A/c, we write the cost of sales and abnormal
losses and on the credit side sales and abnormal gain. Based on the policy
as regards overheads, the under / over absorption may also be written on
the debit side or as the case may be on credit side. We close this a/c by
transferring the profit (loss) to General Ledger adjustment A/c.
(2) TRIAL BALANCE:
Obviously, the closing balances would be inventory accounts General
Ledger Adjustment accounts and Overhead A/c's (If the policy is to carry
forward the difference).

65
 INTER CA. – COSTING

(III) INTEGRAL ACCOUNTING SYSTEM :

Here, the balance sheet is also required and therefore General Ledger adjustment
account (dummy A/c) obliviously has no place. If there are some items of financial
nature (Income Tax, Fine Penalty etc.), then after preparing costing profit & loss A/c,
we prepare Profit & Loss A/c and we write all the items of Financial nature in the
profit and loss A/c. In that case, the net profit that we get in Costing Profit & Loss
A/c is transferred to this Profit and Loss A/c. Final Net profit is then to be transferred
to Reserve and Surplus A/c.
As regards overheads, the under or over-recovery of overheads is to be transferred
to be adjusted in current year only. Then, there are as many more accounts as the
number of balance sheet items in the problem. We give very normal two effects to
every transaction and then close all the accounts. Finally, we prepare trial balance
or, as the case may be, the balance sheet.

RECONCILIATION STATEMENT
In a non-integral system of accounting, where costing & financial books are kept separate,
there will be two profit figures emerging from each set of accounts. Every company would
like to know why there is difference in the two profit figures. The difference could be due
to:
1. Expenses or incomes recorded only in Financial Accounting.
2. Notional Expenses recorded only in Cost Accounting.
3. Difference in the valuation of stock.
Here the difference is due to either valuation difference (in one set of books the
accountant might follow FIFO and in the other the other accountant might follow
LIFO) or principle difference (which happens only in case of finished goods).
4. Under or over absorption of overheads.
In costing we generally follow absorption costing where absorption rate is found
out at the beginning of the year, which is Budgeted overheads/Budgeted level of
activity. This absorption rate is applied during the year to get absorbed overheads.
In financial accounts we generally write down actual overheads.

IMPORTANT THEORY QUESTIONS FOR EXAMINATION

Question 1
Why is it necessary to reconcile the Profits between the Cost Accounts and Financial
Accounts? (May 2004, 5 Marks)

Answer
When the cost and financial accounts are kept separately, It is imperative that these
should be reconciled, otherwise the cost accounts would not be reliable. The reconciliation
of two set of accounts can be made, if both the sets contain sufficient detail as would
enable the causes of differences to be located. It is, therefore, important that in the
financial accounts, the expenses should be analysed in the same way as in cost accounts.
It is important to know the causes which generally give rise to differences in the costs &
financial accounts. These are:
(i) Items included in financial accounts but not in cost accounts Appropriation of profits
• Income-tax
• Transfer to reserve
• Dividends paid
• Goodwill / preliminary expenses written off
Pure financial items
• Interest, dividends
• Losses on sale of investments
• Expenses of Co.’s share transfer office
• Damages & penalties
(ii) Items included in cost accounts but not in financial accounts
• Opportunity cost of capital
• Notional rent
(iii) Under / Over absorption of expenses in cost accounts
(iv) Different bases of inventory valuation
Motivation for reconciliation are:
• To ensure reliability of cost data
• To ensure ascertainment of correct product cost
• To ensure correct decision making by the management based on Cost & Financial
data
• To report fruitful financial / cost data.

PROCESS & OPERATION

COSTING

THEORY SECTION

Process costing is followed by those company in which Raw Material has to pass through
different stages of manufacture before it is converted into Finished Goods. Each stage
of manufacture is known as process Accounts. It is followed by cloth manufacturing
company, leather goods manufacture company, petrol & oil manufacturing company etc.
Main purpose of process costing is to find out cost p.u. at every stage of manufacture &
to value work in progress.
Process I A/c
Units ` Units `
To Opening WIP xx xx By Normal Loss xx xx
To Raw Material Introduced xx xx By Abnormal Loss xx xx
To Direct Labour xx By Output transferred to xx xx
To Direct Expenses xx Process II A/c
To Factory Overheads xx By Closing WIP xx xx
To Abnormal Gain xx xx
xx xx xx xx

Normal Loss: It is expected loss & not actual loss. It is calculated based on past experience.
It is unavoidable. Normal loss is always valued at scrap value.
Abnormal Loss: Abnormal loss arises whenever actual loss is more than normal loss.
Whenever there is abnormal loss actual output received will be less than normal
expected Output. Abnormal loss is always valued at cost price.
Abnormal Loss = Actual Loss - Normal Loss
Abnormal Gain: Abnormal gain arises whenever actual loss is less than normal loss. It
represents extra Output produced. Abnormal gain is always valued at cost price.
Abnormal Gain = Normal Loss - Actual Loss

WEIGHTED AVERAGE METHOD (WAM)

VIRSUS FIFO METHOD
(1) Presumption:
(i) FIFO presumes that opening W.I.P. is first processed further and forms part of
units completed.
(ii) Weighted Average method makes no such presumptions and it only says that it
forms part of the units completed + closing W.I.P.
(2) Statement of Equivalent production:
(i) Under FIFO, we break up the finished output in two parts, viz, opening stock
processed further and units completely processed because the underlying
presumption is that opening stock is processed further.
(ii) Under W.A.M. we write the finished output as it is without breaking it up because
we do not know whether it forms part of finished output or closing W.I.P.
In a way therefore whereas FIFO method gives us the equivalent output of this
period, Weighted Average method gives the equivalent output at the end of the
period.
(3) Statement of cost per unit:
(i) Under FIFO method the cost of opening stock is directly to be charged to finished
output only and therefore we divide only current period's cost by current output.
(ii) Under weighted Average method, we charge the cost at the end of the period,
element wise (i.e. cost of opening W.I.P. + Current cost) to the output at the end
of the period.
(4) Apportionment of cost :
(i) Under FIFO, in respect of finished output, we apportion the cost partly to
opening stock processed further and partly to units completely processed.
(ii) Under WAM, since the finished output is not broken up in two part at all, the
apportionment is to be made only to finished output.
(5) Factory cost of output:
(i) Under FIFO, this is sum total of three different figures, viz, the cost of opening
stock, cost of opening stock processed further and cost of units completely
processed. Accordingly, we put this working note only to get 3 figures from
different places, so that the final figure can be calculated.
(ii) Under WAM, since output is not broken up at all, we get total apportionment

79
 INTER CA. – COSTING

when we make normal apportionment and therefore this note is not at all
required.
(6) When to follow which method:
(i) The FIFO method requires the information about degrees of completion of
opening W.I.P. and therefore whenever it is not given, it will fail and one has to
follow WAM.
(ii) WAM requires the information about the break up of opening stock valuation
element wise and therefore whenever the break up is not given, the method
would fail and one has to follow FIFO.
(iii) If the degree of completion of opening stock as well as the break up of its
valuation are given then, if the instruction is given, we accordingly select the
methods and in the absence of instruction, as such we are free to follow any of
the two methods though it is better to follow FIFO.
(7) Common Areas:
All other areas except those noted above are same. (For example, the treatment to
be given to abnormal loss and gain, regardless of the method, would be the same.)
(8) Final Results:
The two methods would normally give different results except under the following
situations where the two methods would give same result.
(i) The cost per equivalent unit of each element last period and this period is
same.
(ii) There is no opening W.I.P.
(iii) There is no new production in the current period.
(iv) There is no closing WIP.
(v) There is no finished output.

PROCESS ACCOUNT FOR PROCESS OTHER THAN PROCESS I

In such Problems, we have two types of materials. One is output of previous process (say
cloth) and other is material used in this process (say colour). In such cases as regards
degree of completion, a few things are very obvious and therefore no information would
be given in the problem. They are to be taken for granted. They are as given below:
(1) Closing Work-In-Progress always includes output of previous process completely
(cloth) and therefore degree of completion is always 100%. As regards materials
used during the process the degree of completion could be anything between 0% to
99% and this information would always be given in the problem.
(2) In respect of Abnormal Loss, the raw material that comes from the previous process

80
 INTER CA. – COSTING

is obviously completely lost and therefore the degree of completion is always 100%.
Depending on the stage of rejection, the degree of completion of material used
during the process could be anywhere between 0% to 99% and therefore information
would be given.
(3) As regards Opening Stock processed further, the material that came from previous
process is completely there in the opening stock, and therefore there is no question
of processing further. In other words degree of completion of further processing
would be zero. In respect of other raw material, information would always be given.
To conclude, the degree of completion of raw material of previous process is always 100%
in respect of Abnormal Loss and closing work-in-progress and always 0% in respect of
further processing of Opening Stock.

Normal Loss, Abnormal Loss, Abnormal Gain

Points to be Remembered
(1) Normal Loss:
(i) This is not an output item and therefore it is not to be written in the statement
of equivalent production.
(ii) The scrap value that we credit to the process A/c has to be deducted, as a
matter of principle, from prime cost. But conventionally, it is always deducted
from material cost.
(iii) Deducting scrap value from material cost implies that the scrap value pertains
to each and every unit and further the entire scrap value pertains to the material
cost.
Calculating of normal loss
Normal loss can be percentage of
(A) As a matter of policy:
It can be as percentage of input.
It can be as percentage of through - put
(Opening WIP + Units put in - Closing WIP)
(B) Random Methods:
(Instruction to be given in the question)
(i) Percentage of Opening units + units put in
(ii) Units put in - closing WIP
(iii) Percentage of Input
(iv) Percentage of opening units + units put in - closing WIP

81
 INTER CA. – COSTING

(2) Abnormal Loss:

(i) This is as good as output item and therefore to be written in the statement of
equivalent production.
(ii) The degree of completion would be given in the exam question but, if not given
then we have to put the presumption. As such any presumption would work
through one may take 100% everywhere.
(3) Abnormal Gain:
(i) This is to be written in the statement of equivalent production but it is to be
deducted from other output items.
(ii) Degree of completion of abnormal gain is always to be taken as 100%.

IMPORTANT THEORY QUESTIONS FOR EXAMINATION FOR PROCESS COSTING

Question 1
Distinguish between job costing and process costing?

Answer
The main points, which distinguishes job costing and process costing are as below:
Job Costing Process Costing
(i) A Job is carried out or a product is The process of producing the product has a
produced by specific orders. continuous flow and the product produced
is homogeneous.
(ii) Costs are determined for each job. Costs are compiled on time basis i.e., for
production of a given accounting period
for each process or department.
(iii) Each job is separate and independent Products lose their individual identity as
of other jobs. they are manufactured in a continuous
flow.
(iv) Each job or order has a number and The unit cost of process is an average cost
costs are collected against the same for the period.

(v) Costs are computed when a job is Costs are calculated at the end of the cost
completed. The cost of a job may period. The unit cost of a process may be
be determined by adding all costs computed by dividing the total cost for the
against the job. period by the output of the process during
that period.
(vi) As production is not continuous and Process of production is usually
each job may be different, so more standardized and is therefore, quite stable.
managerial attention is required for Hence control here is comparatively easier
effective control.

Question 2
Distinguish between Operating Costing and Operation Costing.

Answer
Operating Costing: It is a method of costing applied by undertakings which provide service
rather than production of commodities. Like unit costing and process costing, operating

94
 INTER CA. – COSTING

costing is thus a form of operation costing.

The emphasis under operating costing is on the ascertainment of cost of rendering
services rather than on the cost of manufacturing a product. It is applied by transport
companies, gas and water works, electricity supply companies, canteens, hospitals,
theatres, school etc. Within an organisation itself certain departments too are known
as service departments which provide ancillary services to the production departments.
For example, maintenance department; power house; boiler house; canteen; hospital;
internal transport.
Operation Costing: It represent a refinement of process costing. In this each operation
instead of each process of stage of production is separately costed. This may offer better
scope for control. At the end of each operation, the unit operation cost may be computed
by dividing the total operation cost by total output.

Question 3
Write a short note on unit costing method for ascertaining product cost.
 (November 1995, 6 Marks)
Answer
It is a form of process or operation costing. It is suitable where only one product or a
few grades of the same product involving a single process or operation is produced.
Under this system the expenditure is not analysed in as much detail as is necessary for
job costing because the whole of the expenditure is normally incurred for only one type
of product but where, however, articles produced vary in grades and sizes, it is necessary
to analyse the appropriate charges for ascertaining the cost of articles. On dividing the
total expenditure by the number of units produced, the cost per unit is ascertained. This
system of costing is suitable for breweries, cement works etc.
In all these cases, unit cost of articles produced requires to be ascertained.
The cost sheets are prepared periodically and usually contain information on the under
mentioned points :
(i) Cost of materials consumed with details.
(ii) Cost of labour with details.
(iii) Work indirect expenses with details.
(iv) Office and administrative expenses in lump-sum.
(v) Abnormal losses and gains are separated and not mixed with costs.

Question 4
"The value of scrap generated in a process should be credited to the process account." Do
you agree with this statement? Give reasons.
 (November 1995, 2 Marks)
Answer
This statement is not correct The value of scrap (as normal loss) received from its sale
is credited to the process account. But the value of scrap received from its sale under
abnormal conditions should be credited to Abnormal Loss Account.

Question 5
Explain normal wastage, abnormal wastage and abnormal gain and state, how they
should be dealt with in process Cost Accounts.  (November 1998, 6 Marks)

Answer
Normal wastage: It is defined as the loss of material which is inherent in the nature of
work. Such wastage can be estimated in advance on the basis of past experience or
technical specifications. If the wastage is within the specified limit, it is considered as
normal. Suppose a company states that the normal wastage in Process A will be 5% of
input. In such a case wastage upto 5% of input will be considered as normal wastage of
the process.
When the wastage fetches no value, the cost of normal wastage is absorbed by good
production units of the process and the cost per unit of good production is increased
accordingly. If the normal wastage realises some value, the value is credited to the
process account to arrive at normal cost of normal output.
Abnormal wastage: It is defined as the wastage which is not inherent to manufacturing
operations. This type of wastage may occur to the carelessness of workers, a bad plant,
design etc. Such a wastage cannot be estimated in advance.
The units representing abnormal wastage are valued like good, units produced and
debited to the separate account which is known as abnormal wastage account. If the
abnormal wastage fetches some value, the same is credited to abnormal wastage
account. The balance of abnormal wastage account i.e. difference between value of units
representing abnormal wastage minus realisation value is transferred to Costing profit
and loss account for .the year.
Abnormal gain: It is defined as unexpected gain in production under normal conditions.
In other words, if the actual process waste is less than the estimated normal waste,
the difference is considered as abnormal gain. Suppose, a Company states that 10%

96
 INTER CA. – COSTING

of its input will be normal loss of process A. If input of this company is 100 units then
its normal output should be 90 units. If actual output is 95 units, then, 5 units will
represent its abnormal gain! These units which represents abnormal gain are valued like
normal output of the process. The concerned process account is debited with the quantity
and value of abnormal gain. The abnormal gain account is credited with the figure of
abnormal gain amount. Abnormal gain being the result of actual wastage, or loss being
less than the normal. The scrap realisation shown against normal wastage gets reduced
by the scrap value of abnormal gain. Consequently; there is an apparent loss by way
of reduction in the scrap realisation attributable to abnormal effectives. This loss is set
off against abnormal effectives by debiting, the account. The balance; of this account
becomes abnormal gain and is transferred to; costing profit and loss account.

JOINT PRODUCTS & BY

PRODUCTS

THEORY SECTION
(1) MEANING:
There are so many products which emerge jointly and for which we incur common
cost. The products which emerge jointly are all known as joint products. They are
separated at a point known as Separation point or Split off point. Some of these
products are then classified as Main Products & others as By-products. Main products
are those products which are independently profitable and the sale price per unit
is significantly more than proportionate common expenditure in the factory. The
production manager tries his level best to get as much output of these products as
possible. The By-products are those products which have insignificant sale value
and it is less than proportionate common expenditure. Given a choice, he would
never want to have this product. The common expenditure we incur is known as Joint
Cost and in this chapter we need to know two things. viz. how to apportion the joint
cost and the depth of processing of Joint Products.

(2) ACCOUNTING METHODS:

There are, in all, two accounting methods as explained below :
(i) The total joint cost is apportioned to all the joint products including by-
products.
(ii) The by-products are treated as scrap and the scrap value (sales value) of
output of by-product is deducted from total joint cost and balance net joint
cost is apportioned only to the main products.

98
 INTER CA. – COSTING

(3) METHODS OF APPORTIONMENT OF JOINT COST:

There are three methods in all as explained below:
(1) OUTPUT / PHYSICAL MEASURE METHOD: Under this method, joint cost is charged
to various products in the ratio of their output. In other words, the joint cost per
unit of output that will be charged to various products would be the same.
Suitability: If all the products are main products & sales prices are more or
less same, then it would mean that various joint products are more or less
identical and in such cases, they all can be treated on par. Only in such cases,
this method has some justification.
Not Suitable: Whenever we have joint products, the sales prices of which are
significantly different, there would be no justification in charging same cost to
these different products.
(2) Sales value (of output at separation / Split off point) method : Under this method,
the Joint cost is apportioned to various products in the ratio of sales value of
output of various products at separation point. In other words the product
which has higher sales price will be made to bear more burden of cost per
unit. This method is most reasonable since it charges more cost to the product
which makes us incur more amount of cost. (i.e. more profitable products). If
the choice is left to us, we must always use or follow this method only.
(3) Net Relative sales value / net realisable value / notional sales value method: As already
noted, given a choice, we always follow sales value method. But sometimes,
the Joint products are either not marketable at split off point or they may be
marketable but are not marketed by the company. In such cases, sales value of
output at separation point would not be known and therefore the sales value
method would fail.
Under this method, we first calculate notional sales value of the output of
products by deducting specific expenses incurred after separation point from
the final sales value and we apportion the Joint cost in the ratio of such sales
value of the output of various joint products. Whenever sales value method
fails, this is the next best method. It should be noted that if some products are
sold at separation point and some are processed further then, we follow real
sales value method for products which are sold at separation point and this
notional sales value method is to be used in respect of the products for which,
the sales value of which at separation point, cannot be known.

99
 INTER CA. – COSTING

(4) DEPTH OF PROCESSING:

Whenever we have the options of selling the product at separation point or processing
it further, we should follow the following steps to decide the depth of processing.
(1) We should find out the sales value of the product at separation point and sales
value if the product is processed further and then sold. The difference between
these two is additional sales value that we will get, if the product is processed
further. (Sales value of output of Ghee minus sales value of output of butter).
(2) We should now find out additional cost (variable and fixed both) that we would
be incurring if and only if the product is processed further. In other words,
the cost that will be incurred irrespective of whether the product is processed
further or not must be ignored.
(3) If the additional sales value (step1) is more than the additional cost (step 2), the
product should be processed further. When additional cost exceeds additional
sales value, the product should be sold at separation point.
(4) The Joint Cost is incurred before the separation point and therefore we must
never apportion the same while deciding the depth of processing.

100
 INTER CA. – COSTING

(5) STANDARD PROFIT STATEMENT:

This chapter is part of Cost-Sheet and therefore it is possible that we may be asked
to prepare Cost-Sheet or Profit Statement. All that this chapter teaches us is how
to get factory cost of various products when common cost is incurred for the benefit
of two or more products. Once that is done we get factory cost of each and every
joint product and with the help of other cost information and by following usual
principles, we can easily prepare Cost-Sheet or Profit Statement.
Usually, the joint cost we have to apportion and sales and other information’s are
given so that we get profit as balancing figure. However in general if all the items,
except any one of them, are given then what is not given can be taken as balancing
figure. In this chapter, joint cost can be the balancing figure.
The following standard statement can be used for this purpose, to have cost sheet
for each product.

Manufacturing Cost `
(a) Joint Cost ***
(b) Separate Cost ***
Factory Cost ***
Add : Administrative Overheads ***

IMPORTANT THEORY QUESTIONS FOR EXAMINATION

Question 1
How would you account for by-product in cost accounting:
(i) When they are of small total value.
(ii) When they are of considerable total value.
(iii) When they require further processing.

Answer
Treatment of By-product in Cost Accounting:
(i) When they are of small total value : If the amount realised from the sale of by-product
is small, it may be dealt in any one of the following two ways:
(1) The sale value of the by-product may be credited to the Profit and Loss Account
and no credit be given in the cost accounts. The credit to the Profit and Loss
Account here is treated either as miscellaneous income or as additional sales
revenue.
(2) The sale proceeds of the by-product may be treated as deductions from the total
costs. The sale proceeds in fact should be deducted either from the production
cost or from the cost of sales.
(ii) When they are of considerable total value: In this case by-products may be regarded
as joint products. To determine exact cost of by-products the costs incurred upto the
point of separation, should be apportioned over by-products and joint products by
using a logical basis. In this case, the joint costs may be divided over joint products
and by-products by using physical unit method (at the point of split off) or ultimate
selling price (if sold).
(iii) When they require further processing: In this case, the net realisable value of the by-
product at the split-off point may be arrived at by subtracting the further processing
cost from the realisable value of by-products.

111
 INTER CA. – COSTING

Question 2
Distinguish between Joint Product and By Product

Answer
Joint-product and By-product: Joint products and by-products arise from many industrial
processes wherein, from a set of common inputs, two or more products of varying
importance are obtained. For example, when hydrogenated oil is processed, along with
oil, oxygen gas is also produced molasses is produced along with sugar automatically.
Some of the products are not of much importance from the sales-value point of view,
like molasses in the case of sugar, but in some cases the products are all of importance.
Usually, the term by-product is used in the former case and joint products in the other
case. One can see that distinction between joint products and by-products turns on their
relative importance which sometimes makes it difficult to make a distinction. However,
one point to keep note of it is that, usually, in the case of joint products further processing
is required, after initial common process, before the products are sold.
Thus joint products ‘represent two or more products separated in the course of the same
processing operations, usually requiring further processing, each product being in such
proportion that no single product can be designated as a major product.’
By-products may be defined as any saleable or usual value incidentally produced in
addition to the product.’ Sometimes the word wastage or even loss is used to denote
what is really a by-product. For example, in a thermal power plant, ash will remain
when coal is used up. In a place where good deal of construction activity is going on, the
ash will have a market-it is a case of by-product even if it is termed as wastage.

IMPORTANT THEORY QUESTIONS FOR EXAMINATION

Question 1
Explain briefly, what do you understand by Operating Costing. How are composite units
computed?  (3 Marks, November 2009)

Answer
Operating Costing: It is method of ascertaining costs of providing or operating a service.
This method of costing is applied by those undertakings which provide services rather
than production of commodities. This method of costing is used by transport companies,
gas and water works departments, electricity supply companies, canteens, hospitals,
theatres, schools etc.
Composite units may be computed in two ways:
(a) Absolute (weighted average) tones kms, quintal kms etc.
(b) Commercial (simple average) tonnes kms, quintal kms etc.
Absolute tonnes-kms are the sum total of tonnes kms arrived at by multiplying various
distances by respective load quantities carried.
Commercial tonnes-kms, are arrived at by multiplying total distance kms, by average
load quantity.

Question 2
What do you understand by operating costing? How are composite units computed?
 (4 Marks, November 2012)
Answer
Meaning of Operating Costing: Operating Costing is a method of ascertaining costs of
providing or operating a service. This method of costing is applied by those undertakings
which provide services rather than production of commodities. This costing method is
usually made use of by transport companies, gas and water works departments, electricity
supply companies, canteens, hospitals, theatres, schools etc.
Computation of composite units: When two units are merged into one it is called Composite
units. It is explained with example as follows.
Composite units i.e. tonnes kms., quintal kms. etc. may be computed in two ways.
(i) Absolute (weighted average) tonnes-kms.
Absolute tonnes-kms, are the sum total of tonnes-kms., arrived at by multiplying
various distances by respective load quantities carried.
(ii) Commercial (simple average) tonnes-kms. Commercial tonnes-kms., are arrived at
by multiplying total distance kms., by average load quantity.

CONTRACT COSTING

THEORY SECTION

Contract costing is mainly followed by those companies which are in the business of
construction. There are two parties:
1.
Contractor (Seller) 2. Contractee (Buyer)
Contractor is the person who undertakes construction activity.
Contractee is the person on whose behalf the construction activity is undertaken.
Contract price means selling price of contract.
Format of contract account

NOTES:
1. Closing work in progress of 1st year will become opening work in progress in 2nd
year.
2. Material sold can be recorded either at cost price or at selling price. If it is recorded
at selling price then profit / loss on sale is to be transferred to P & L A/c.

3. Work Certified:
It represent that portion of contract work which is completed & for which certificate
of completion is received either from the Architect or from Surveyor. Work certified is
always valued at contract price.
4. Work Uncertified:
It represent that portion of contract work which is completed & for which certificate
of completion is not received. Work uncertified is always valued at cost price.
5. Progress Payment Received:
It represents advance received from the contractee against work certified.
Cash / Bank A/c Dr.
To Contractee's A/c
6. Retention Money:
It represent amount retained by the contractee till the completion of contract. From
retention money we can find out progress payment received.
E.g. : Retention money is 20% that means payment received will be 80% of work
certified.

IMPORTANT THEORY QUESTIONS FOR EXAMINATION

Question 1
Write note on cost-plus-contracts.  (Nov. 2000, 2 Marks)

Answer
These contracts provide for the payment by the contractee of the actual cost of manufacture
plus a stipulated profit, mutually decided between the two parties.
The main features of these contracts are as follows:
1. The practice of cost-plus contracts is adopted in the case of those contracts where the
probable cost of the contracts cannot be ascertained in advance with a reasonable
accuracy.
2. These contracts are preferred when the cost of material and labour is not steady
and the contract completion may take number of years.
3. The different costs to be included in the execution of the contract are mutually agreed,
so that no dispute may arise in future in this respect. Under such type of contracts,
contractee is allowed to check or scrutinize the concerned books, documents and
accounts.
4. Such a contract offers a fair price to the contractee and also a reasonable profit to
the contractor.
5. The contract price here is ascertained by adding a fixed and mutually pre-decided
component of profit to the total cost of the work.

Question 2
Write notes on Escalation Clause.  (Nov. 2000, 2 Marks, May 1994, 4 Marks)

Answer
Escalation Clause: This clause is usually provided in the contracts as a safeguard against
any likely changes in the price or utilization of material and labour. If during the period
of execution of a contract, the prices of materials or labour rise beyond a certain limit,
the contract price will be increased by an agreed amount. Inclusion of such a term in a
contract deed is known as an 'escalation clause'
An escalation clause usually relates to change in price of inputs, it may also be extended
to increased consumption or utilization of quantities of materials, labour etc. In such a
situation the contractor has to satisfy the contractee that the increased utilization is not
due to his inefficiency.

133
 INTER CA. – COSTING

Question 3
What are the main advantages of cost plus contract?
 (2 Marks, May 2008; November 2009)
Answer
Costs plus contracts have the following advantages:
1. The contractor is assured of a fixed percentage of profit. There is no risk of incurring
any loss on the contract.
2. It is useful especially when the work to be done is not definitely fixed at the time of
making the estimate.
3. Contractee can ensure himself about “the cost of the contract”, as he is empowered
to examine the books and document of the contractor to ascertain the veracity of
the cost of the contract.

Question 4
Explain the terms Retention money in contract costing.
 (4 Marks, November 2011)
Answer
Retention money in contract Costing:
A the default risk in contract contractor does not receive the full payment of work certified
by the surveyor of work certified by the surveyor. Contractee retains some amount to be
paid after some time, when it is ensured that there is no default in the work done by the
contractor. If any deficiency or defect is noticed it is to be rectified by the contractor before
the release of the retention money. Thus retention money provides a safe guard against

B. HOW MUCH TO BUY / MANUFACTURE AT A TIME:

(i) Total Ca or Acquisition cost or ordering cost :
The Acquisition cost is that cost which we specifically incur, every time the order
for buying the raw material is placed. The examples are paper & other stationery
cost that we incur for preparing the purchase requisition, purchase order etc., the
postage cost incurred for inviting the quotations, telephone expenses to be incurred,
fuel or carriage inward and so on.
The acquisition cost, as such, depends on the number of times that we buy but the
number of times that we buy itself would depend on how much we buy every time.
The more we buy at a time, the less the number of times we buy & therefore the less
would be our Ca. Thus, to minimise Ca, we should buy less no. of times.
It should be noted that expenses which are unaffected by the number of times
we buy are not acquisition costs at all (e.g. Salary of purchase department staff,
depreciation of vehicles etc.)

(ii) Total Ci or carrying cost:

This cost depends on the average stock that we carry in our inventory. The average
stock is half of how much we buy every time.
Interest cost, real or notional, that we incur on investments in our inventory or the
insurance premium that we pay to insure the stock against certain risk are examples
of carrying cost items.
The more we buy at a time, the more would be our investment and accordingly, the
more would be our carrying cost. To minimise Ci, we must buy less at a time so that
the investment & consequently, the carrying cost would get reduced.
It should be noted that expenses which are unaffected by quantity of stock that we
keep are not Ci items (e.g. salary of store keeper, depreciation or rent warehouse

136
 INTER CA. – COSTING

etc.). Also unless instructed otherwise any change in purchase price or rate of interest
would change Ci.

(iii) Ca v/s Ci :
These two cost items are equally strong but conflicting cost items. If one tries to
minimise one of them the other would automatically increase. For example, to
minimise Ca, we should buy less number of times which means we should buy more
at a time. But if we buy more at a time, the Ci would increase.
The EOQ does one very important job of striking a good balance between the two by
making the two equal.

B. WHEN TO BUY:
(1) Re-order level (ROL):
This is the stock level which, when reached, signifies that the action should be
taken to procure fresh quantity of raw material. The ROL has to be such that
the stock out is eliminated completely.
If the stock-out is not to occur, then, we must find out the maximum-possible
requirements of raw material during the maximum possible lead time that
lapses before we get fresh quantity of Raw Material.
Therefore ROL= Maximum consumption in maximum lead time + safety stock /
buffer stock / base stock (if given).

(2) Maximum (possible) stock:

After ROL is reached & before we get the fresh quantity, at least some consumption
would take place out of ROL quantity. If we want maximum possible stock, the
consumption should be minimum possible. Just after that consumption is over,
we would get fresh quantity of Raw Material which would be Re-order quantity
(which could be EOQ or other than EOQ).
Therefore Maximum possible stock = ROL ¬– Minimum consumption in minimum
lead time + Re-order quantity.

(3) Minimum (desirable) stock:

The minimum desirable level is the usual stock. Once our stock level reaches
below minimum level, it signifies that the conditions are unusual & unless
some urgent steps are taken, the stock-out may occur. However as long as the
conditions are normal we have nothing to worry about.

137
 INTER CA. – COSTING

The maximum lead time & the maximum consumption occur only rarely & so is
the case with minimum consumption & minimum lead time. These are extremes
& do not occur regularly. What happens usually is the average lead time &
average consumption. In other words as long as reduction from ROL is equal to
average consumption in average lead time, we have nothing to worry about as
that is something very normal and it happens in every inventory cycle. It is only
when, the stock goes below that level, that must make us worry.
Therefore, the minimum stock = ROL – Average consumption in average lead
time.

(4) Average stock =

(5) Danger Level:
1. Level at which emergency purchase action is made to replenish stock.
2. Level at which stocks are issued only on "most needed" basis.
Average consumption x Emergency lead time

IMPORTANT THEORY QUESTIONS FOR EXAMINATION

Question 1
List five types of inefficiency in the use of materials that may be discovered as the result
of investigating material quantity variances. What measures may be taken in each such
situation to prevent their recurrence?

Answer
The five types of inefficiency in the use of materials that may be discovered as a result of
investigating materials quantity variances are as follows :
1. Purchase of inferior quality of materials.
2. Inefficient labour force leading to excessive utilisation of materials.
3. Defective machines, tools and equipments and bad or improper maintenance leading
to breakdowns resulting in excessive usage of materials.
4. Inaccurate technical specifications and slackness in inspection may cause more
rejections, resulting in greater requirement of materials for rectification of defects.
5. Faulty material processing.
The measures which may be taken in each of the above situations to prevent their
recurrence in future are as below :
1. To ensure the purchase of proper quality of material, each lot of material
purchased should be inspected in accordance with the terms and conditions
of purchase before they are accepted and issued for production. The extent
of inspection may depend on the circumstances. For instance, when materials
are of small value or where the quality of raw materials does not appreciably
affect the final product, the inspection may not be very rigid. In such a case,
inspection may be carried out by taking random samples. However, for
materials of vital importance like raw materials for explosive factories or for
pharmaceutical concerns where material cost is high, a rigid or strict inspection
will be necessary.
2. Labour inefficiency can be reduced by adopting following measures :
(a) Imparting on-the-job training to workers.
(b) Supervising the workers while performing the jobs.
(c) Evaluating workers performance.
(d) Incorporating incentive schemes for workers.
(e) Reducing labour turnover ratio.
3. The wastage of material can also be reduced by properly maintaining machines,

151
 INTER CA. – COSTING

tools and other equipment. The concern should adopt a policy of preventive
maintenance. The use of such a policy will reduce machine down time and
over-consumption of materials. Besides this, workers must be educated to
realise fully the importance of tools and equipment in their day-to-day work.
4. A reduction in the number of defective units, in this case may automatically
bring down the excessive consumption of material required for rectification
of defects. Reduction in the number of defectives can be achieved by laying
down accurate technical specifications, standards for materials and tactfully
handling the problem of slackness.
5. Faulty material processing also results in excess consumption of material.
The supervisors at the shop floor level should educate and guide the workers
properly so that they make use of the correct procedure laid down for processing
raw materials.

Question 2
Discuss briefly how the following items are to be treated in costs :
(i) Carriage inwards raw materials
(ii) Storage losses
(iii) Cash discount received
(iv) Insurance costs on stocks of raw materials.

Answer
(i) Carriage inwards on raw materials: It represents the expenditure incurred in bringing
raw materials to factory from outside. This expense is directly allocated to materials
and thus forms a part of the .cost of such materials. When this is not practicable
and allocation to specific items of materials is difficult, the expense is treated as
manufacturing overhead and is charged to cost of production at a re-determined
rate. In some of the undertakings the practice is to charge these expenses as a
percentage of cost, weight or some other physical unit of material.
(ii) Storage losses: The losses arising out of storage of material can be classified into
two categories. The treatment of losses under each category in Cost Accounts is as
under:
(a) Losses due to reasons like evaporation, shrinkage, absorption and moisture, etc.
are considered as normal losses. Such losses are absorbed by good production
units by inflating the cost of material issued for production.
(b) Losses due to fire, flood, storm, theft etc. are treated as abnormal losses. If

152
 INTER CA. – COSTING

these losses are heavy and are not recoverable from the insurance authorities,
it is preferred to charge them to Costing Profit and Loss Account.
(iii) Cash discount received: It is an allowance given by the vendor for prompt payment
of material price. The opinion among accountants about its treatment differs. Two
prevalent approaches for treating the cash discount received are as follows:
(a) The cash discount received in the course of materials buying should be deducted
from the invoice price of the materials. This way the discount received will
reduce the purchase price of the materials.
(b) It may be treated as an item of financial nature and therefore be kept outside
the purview of cost accounting. However, it can be dealt in the following manner.
The full invoice price should be charged to the material account crediting the
suppliers with the net invoice price, and the discount earned account with
the amount of cash discount received. If the prompt payment could not be
made, the discount lost is debited to the discount lost account. Any difference
between the discount earned and discount lost may be treated as an item of
administrative overhead.
(iv) Insurance costs on stocks of raw materials : The amount paid as insurance costs
(insurance premium) on stocks of raw materials is meant for covering the risk which
may arise due to fire, theft, riot etc. The insurance cost is apportioned over different
materials on the basis of their value. This cost may be charged directly to the cost
of material.

Question 3
Distinguish between spoilage and defectives in a manufacturing company. Discuss their
treatment in cost accounts and suggest a procedure for their control.

Answer
Spoilage can be defined as the materials which are badly damaged in the course of
manufacturing operations to the extent that they cannot be rectified economically and
hence taken out of process, to be disposed of in some manner without further processing.
Spoilage may be either normal or abnormal.
Defective products are such semi-finished or finished products produced by a
manufacturing unit, which are not in conformity with laid-down standard or dimensional
specifications. Defectives produced can be re-worked or reconditioned by the application
of additional materials, labour and / or processing and brought to the point of either
standard or sub-standard product. The costs incurred for reconditioning are known as

153
 INTER CA. – COSTING

the "Costs of re-operations of the defectives". Defective production may be the result
of various causes such as sub-standard materials, bad-workmanship, carelessness in
planning, laxity in inspection etc.
The difference between spoilage and defectives is that while spoilage cannot be repaired
or reconditioned, defectives can be rectified and transformed, either back to standard
production or to seconds.
Treatment of spoilage and defectives in Cost Accounting : Under Cost Accounts normal spoilage
costs (i.e., which is inherent in the operation) are included in cost either by charging the
loss due to spoilage to the production order or charging it to production overhead so that
it is spread over all products. Any value realised from the sale of spoilage is credited
to production order or production overhead account, as the case may be. The cost of
abnormal spoilage (i.e. arising out of causes not inherent in manufacturing process) are
charged to the Costing Profit and Loss Account. When spoiled work is the result of rigid
specifications the cost of spoiled work is absorbed by good production while the cost of
disposal is charged to production overheads.
The problem of accounting for defective work is the problem of accounting of the costs of
rectification or rework.
The possible ways of treatment are as below :
(i) Defectives that are considered inherent in the process and are identified as normal
can be recovered by using the following methods:
(a) Charged to good products: The loss is absorbed by good units. This method is
used when 'seconds' have a normal value and defectives rectified into 'seconds'
or 'first' are normal.
(b) Charged to general overheads: When the defectives caused in one department are
reflected only on further processing, the rework costs are charged to general
overheads.
(c) Charged to the departments overheads: If the department responsible for
defectives can be identified then the rectification costs should be charged to
that department.
(d) Charged to Costing Profit and Loss Account: If defectives are abnormal and are
due to causes beyond the control of organisation; the rework cost should be
charged to Costing Profit and Loss Accounts.
(ii) Where defectives are easily identifiable with specific jobs the re-work costs are
debited to the job.
Procedure for the control of Spoilage and Defectives : To control spoilage, allowance for
a normal spoilage should be fixed up and actual spoilage should be compared with

154
 INTER CA. – COSTING

standard set. A systematic procedure of reporting would help control over spoilage.
A spoilage report (as below) would highlight the normal and abnormal spoilage,
the department responsible, the causes of spoilage and the corrective action taken
if any.
Control of defectives may cover the following two areas :
(a) Control over defectives produced
(b) Control over reworking costs.
For exercising effective control over defectives produced and the cost of reworking,
standards for normal percentage of defectives and reworking costs should be
established.

Question 4
Define (i) Replacement Price and (ii) Standard Price. Discuss the objectives of these methods
of pricing of materials and state the circumstances in which they are used.

Answer
(i) Replacement Price is defined as the price at which it is possible to purchase an item,
identical to that which is being replaced or revalued.
(ii) A Standard Price may be defined as a predetermined price fixed for a specified period
on the basis of all factors which may affect future price.
Under Replacement Price method, materials issued are valued at the replacement
costs of the items. This method pre-supposes the determination of the replacement
cost of the materials at the time of each issue, viz., the cost at which identical
materials could be currently purchased. The product cost under this method is at
current market price which is the main objective of the replacement price method.
Replacement Price method is used to value material issues in periods of rising prices
because the cost of material considered in cost of production would be able to
replace the materials at the increased price. This method is used to find the true cost
of production.
The fixation of Standard Price takes into account the quantity of materials to be
purchased, possibility of price fluctuations, etc. The Standard Price is used for
comparison with actual prices from period to period and to measure the efficiency of
the purchase of materials. This is used in conjunction with Standard Costing System
for control purposes and is a tool to the management if fluctuations in prices are not
violent.

 INTER CA. – COSTING

Question 5
Explain the distinction between waste and scrap in the manufacturing process. Discuss
their treatment in cost accounts and suggest a procedure for control.

Answer
Waste: It represents that portion of basic raw materials, which is either lost or which
evaporates or shrinks during a manufacturing process. It may be visible or invisible. But
it has no recovery value.
Scrap: The incidental residue arising from the manufacturing operations, small in quantity
and low in value, recoverable without further processing.
From the definitions of waste and scrap stated above it is quite apparent that waste
cannot be realised whereas scrap can be. Scrap is always visible whereas waste may or
may not be.
Waste can be differentiated as normal and abnormal. Normal waste is absorbed in the
cost of net output, whereas abnormal waste is transferred to the Costing Profit and Loss
Account.
For effective control of waste, normal allowances for yield and waste should be made
from past experience, technical factors and special features of the material process
and product. Actual yield and waste should be compared with anticipated figures and
appropriate actions should be taken where necessary. Responsibility should be fixed on
purchasing, storage, maintenance, production and inspection staff to maintain quality of
the materials and other standards. A systematic procedure for feedback of Achievements
against standards laid should be established.
Scrap may be treated in Cost Accounts in the following ways:
(i) Where the value of scrap is negotiable, it may be excluded from costs. In other
words, the cost of scrap is borne by good units and income from scrap is treated as
other income.
(ii) If the scrap value is considerable, the net sale proceeds of scrap (Gross sales proceeds
of scrap—the cost of selling scrap) is deducted from the material cost or factory
overhead. Under this method the material cost or factory overhead recovery rate
are reduced on account of sale proceeds of scrap. However, no distinction is made
between various processes or jobs.
(iii) Where the various jobs or processes give rise in varying amount of scrap, the scrap
from each job or process is recorded separately and the sale proceeds from the
same credited to the particular job or process. This method is useful where scrap is
of considerable value and does not arise uniformly. However, this would necessitate

156
 INTER CA. – COSTING

the scrap being identified with various jobs or processes. For this purpose detailed
records for scrap will be required.
Control of scrap really arises at the maximum effective utilization of the raw
material. Scrap control does not, therefore, start in the production department; it
starts from the stage of product designing. Thus the most suitable type of materials,
the appropriate size, the right type of equipment and personnel would help getting
maximum quantity of finished product from a given raw material.
The procedure for control of scrap should start with establishing a standard of
scrap with each department, job or process, taking into consideration the nature of
material, the nature of the manufacturing operation, the use of proper equipment,
the size of the material, the employment of proper personnel and defining areas
of responsibility. It is also necessary to establish a scheme of scrap reporting. The
actual scrap should be compared with the predetermined standard, and the reasons
for the difference, if any, should be investigated, corrective action taken, whenever
the actual scrap is found to be more than what is normally allowed. Also, it is to be
ensured that proper supervision is exercised at the scrap generation stage.

Question 6
What is ABC analysis? Discuss its role in a sound system of material control.

Answer
ABC analysis is a technique through which selective control can be exercised over the
various items of inventory. These days the manufacturing units have such a large number
of items in their stores that it is often not possible for the management to pay minute
attention to each and every item. A system is therefore divided by which these items are
classified according to their importance and then selective control exercised. ABC analysis
or Selective Inventory Control is a technique whereby the measure of control over an item
of inventory varies directly with its usage value. In other words, the high value items are
controlled more closely than the items of low value.
To classify the various items according to their usage value, the following procedure is
adopted:
(a) The quantity or the number of parts expected to be used for production in the given
period is estimated.
(b) The quantity as estimated above is multiplied by the unit value of the item.
(c) All the items are then re-arranged according to their usage value in a descending
order.

157
 INTER CA. – COSTING

(d) It would normally be found that a small number of items add upto a very high value.
Thus 5 to 10 percent of total items may constitute 70 to 85 percent of material cost.
Such items are classified as A items. Another 10 to 20 percent of total items may
represent 10 to 20 percent of the total material cost. These items may be categorised
as B items. The rest, i.e. 70 to 85-percent of items, though numerous, will thus form
only 5 to 10 percent of total material cost. These may be called C items.
This classification thus highlights the more significant items. Management can then
exercise a very close control over A items. It may apply occasional control over B
items. As regards C items, it may exercise control only in a general manner. For
example, it may order the quantities of C items annually or once in six months or so.
It is obvious that since C items do not have a high value, the total investment in such
items will not be large.
Regarding A items, the management will have to define the stock levels, i.e.,
maximum, minimum, reordering and danger very carefully. Also a close check on
the consumption of these items will have to be kept. The economic order quantity for
each of the items in this category should be worked out. Similarly other technique
of inventory control should also be applied to A items. It would be appreciated that
since A items constitute the bulk of the investment in the total inventory, it would
be worthwhile to bring them under close control and to apply modern management
inventory control techniques.
ABC analysis helps the management in the following ways:
(1) The investment in inventories is optimised through a close and direct control
over A items. This would naturally release funds which can then be channelised
into more profitable areas. This would raise the overall return on investment
earned by the unit.
(2) The ordering and carrying costs are reduced since the management would
attempt to optimise such costs so far as they relate to the bulk of the items.
(3) If the management seeks to exercise direct control over all the items of
inventory, the inventory control system would become very expensive. ABC
analysis therefore cuts down the cost of the system and relates its cost to the
attendant benefits.
(4) The main objectives of inventory control are fulfilled under this system at the
minimum cost. With scientific control of inventories, the stock turnover rate can
be maintained at comparatively high levels.
The concept of ABC analysis can be used in areas other than inventory also.
This technique basically emphasises that where the items to be controlled are

158
 INTER CA. – COSTING

numerous, one should categorise them according to their importance. Close

control should then be exercised on the most significant category. On the less
important categories, the degree of control maybe related to the benefit from
control.
Thus finally it may be concluded that ABC analysis plays an important role for
a sound system of material control.

Question 7
Distinguish between: Perpetual Inventory System and continuous stock taking.

Answer
(a) Distinction between Perpetual Inventory System and Continuous Stock taking
Perpetual Inventory System: It is a system of stock control followed by the stores
department. Under this system, a continuous record of receipt and issue of material
is maintained by the stores department. In other words, in this system, stock control
cards or bin cards and the stores ledger show clearly the receipts, issues and balance
of all items in stock at all times. This system facilitates planning of production and
ensures that production is not interrupted for want of materials and stores.
Continuous Stock taking: It means physical verification of stores items on a continuous
basis to reveal the position of actual balances. Such a verification is conducted
round the year, thus covering each item of store twice or thrice. Any discrepancies,
irregularities or shortages brought to the notice, as a result of continuous stock
verification are reported to the appropriate authorities for initiating necessary
rectification measures. This system works as a moral check as stores staff and acts
as a deterrent to dishonesty.
A perpetual inventory system is usually supported by a programme of continuous
stock taking. That is continuous stock taking is complementary to the perpetual
inventory system. Sometimes the two terms are considered synonymous but it is not
so. The success of the perpetual inventory system depends upon the maintenance
and upto date writing up of (i) the stores ledger and (ii) bincards/stock control cards,
Continuous stock taking, ensures the veracity of figures shown by the above records.

 INTER CA. – COSTING

Question 8
Distinguish amongst :
1. Spoilage
2. Salvage
3. Rectification
How are they treated in Cost Accounts.

Answer
1. Spoilage: It is the term used for materials which are badly damaged in manufacturing
operations, and they cannot be rectified economically and hence taken out of process
to be disposed of in some manner without further processing. Spoilage maybe either
normal or abnormal.
Normal spoilage (i.e., which is inherent in the operation) costs are included in costs
either by charging the loss due to spoilage to the production order or charging it to
production overhead so that it is spread over all products. Any value realised from
spoilage is credited to production order or production overhead account, as the case
may be.
The cost of abnormal spoilage (i.e., arising out of causes not inherent in manufacturing
process) are charged to the Costing Profit and Loss Account. When spoiled work is the
result of rigid specification, the cost of spoiled work is absorbed by good production
while the cost of disposal is charged to production overhead.
To control spoilage, allowance for normal spoilage should be fixed and actual
spoilage should be compared with standard set. A systematic procedure of reporting
would help control over spoilage. A spoilage report should highlight the normal and
abnormal spoilage, the department responsible, the causes of spoilage and the
corrective action taken, if any.
Salvage: Salvaged material refers to the material retrieved from the spoiled work.
Salvage is the process by which salvaged material is retrieved. The salvaged units of
material are usable in the production.
The value of salvaged material may be credited to the account to which spoilage is
charged.
Rectification: It means bringing back the defective units either to standard units of
production or as seconds, by reworking. The work of rectification in small concern's
is usually entrusted to the production shop, whereas in big concerns, a separate
department carries out the task. Before the start of rectification work an estimate
of the cost of rectification is prepared and compared with the excess value to be

160
 INTER CA. – COSTING

obtained after rectification. The concern only goes ahead with the task of rectification
if the aforesaid comparison is found favourable.
The task of rectification is usually carried out under a 'Rectification Work Order', and
all costs of re-work are collected against this work order for material, labour and
overhead.
If the defective production is inherent in the process of manufacture, and arises as a
normal consequence of productive activities and if it can be identified with specific
jobs, the rectification cost is charged to the jobs as the cost of manufacturing good
units of the product. This will have the effect of adding to the cost of the jobs. If
the expenditure on rectification is considered abnormal, it is excluded from product
costs and charged to Costing Profit and Loss Account.

Question 9
How are normal and abnormal loss of material arising during storage treated in Cost
Accounts? (May 2001, 5 Marks)

Answer
Cost Accounts treatment of normal and abnormal loss of material arising during storage.
The difference between the book balance and actual physical stock, which may either be
gain or loss, should be transferred to Inventory Adjustment Account pending scrutiny to
ascertain the reason for the difference.
If on scrutiny, the difference arrived at is considered as normal, then such a difference
should be transferred to overhead control account and if abnormal, it should be debited
to costing profit and loss account.
In the case of normal losses, an alternative method may be used. Under this method the
price of the material issued to production may be inflated so as to cover the normal loss.

Question 10
Distinguish clearly Bincards and Stores Ledger.  (May 1999, 4 Marks)

Answer
Both bin cards and stores ledger are perpetual inventory records. None of them is a
substitute for the other. These two records may be distinguished from the following points
of view:
(i) Bin card is maintained by the store keeper, while the stores ledger is maintained by
the cost accounting department.

161
 INTER CA. – COSTING

(ii) Bin card is the stores recording document whereas the stores ledger is an accounting
record.
(iii) Bin card contains information with regard to quantities i.e. their receipt, issue and
balance while the stores ledger contains both quantitative and value information in
respect of their receipts, issue and balance.
(iv) In the bin card entries are made at the time when transaction takes place. But in the
stores ledger entries are made only after the transaction has taken place.
(v) Inter departmental transfer of materials appear only in stores ledger.
(vi) Bin cards record each transaction but stores ledger records the same information in
a summarized form.

Question 11
What is Just in Time (JIT) purchases? What are the advantages of such purchases?
 (May 1999, 3 Marks)
Answer
Just in time (JIT) purchases means the purchase of goods or materials such that delivery
immediately precedes their use.
Advantages of JIT purchases:
Main advantages of JIT purchases are as follows :
1. The suppliers of goods or materials cooperates with the company and supply
requisite quantity of goods or materials for which order is placed before the start of
production.
2. JIT purchases results in cost savings for example, the costs of stock out, inventory
carrying, materials handling and breakage are reduced.
3. Due to frequent purchases of raw materials, its issue price is likely to be very close
to the replacement price. Consequently the method of pricing to be followed for
valuing material issues becomes less important for companies using JIT purchasing.
4. JIT purchasing are now attempting to extend daily deliveries to as many areas as
possible so that the goods spend less time in warehouses or on store shelves before
they are exhausted.

Question 13
How is slow moving and non-moving item of stores detected and what steps are necessary
to reduce such stocks?  (November 2001, 4 Marks)

Answer
Detection of slow moving and non-moving item of stores:
The existence of slow moving and non-moving item of stores can be detected in the
following ways.
(i) By preparing and scanning periodic reports showing the status of different items or
stores.
(ii) By calculating the stock holding of various items in terms of number of days/ months
of consumption.
(iii) By computing ratios periodically, relating to the issues as a percentage of average
stock held.
(iv) By implementing the use of a well - designed information system.
Necessary steps to reduce stock of slow moving and non-moving item of stores :
(i) Proper procedure and guidelines should be laid down for the disposal of non-moving
items, before they further deteriorates in value.
(ii) Diversify production to use up such materials.
(iii) Use these materials as substitute, in place of other materials.

THEORY SECTION

1. Calculation of Labour Cost

(I) Time Rate System
Wages depends on Actual hours worked by worker.
→ Basic wages = Time taken (Actual hours worked) x Rate per hour
→ Bonus is to be paid only if workers are efficient.
Efficiency means either time remaining constant, worker are producing more
units or output remaining constant, workers takes less time.

Bonus

Halsey System Rowan System

Bonus = 50% of time saves x Rate per hour Bonus = Time saved x Basic wages
Time Allowed

Time Allowed: It represents standard time allowed by the company to produced

one unit and it includes Normal Idle Time.
Time Saved:
Time Allowed for Actual Production xx
Time taken for Actual Production xx

2. Labour Turnover
It represent change in labour force of a company over a period of time.

Effect of Labour Turnover

Due to Labour Turnover, total Cost will increase because we have to incurr many
expenses like settlement cost, recruitment cost, training cost etc.
Efficiency of new workers will be less than old workers in the beginning and due to
that production will decrease.

All workers are issued job cards by the company. In this job card they have to record
details about actual hours worked on different jobs.
Labour Cost of Job = Labour hours as per job cards x Labour hour rate
Any difference between expected labour hours and total hours as per job card is due
to abnormal idle time. Labour cost of abnormal idle time is to be debited to costing
P & L A/c.

4. Over Time and its Treatment

Overtime premium: Overtime is the amount of wages paid for working beyond normal
working hours as specified by Factories Act or by a mutual agreement between the
workers union and the management. According to Factories Act of 1948, a worker is
entitled for overtime at double the rate of his wages (including allowances) if he works
beyond 9 hours in a day or 48 hours in a week even where the Act is not applicable,
the practice is to pay for overtime work at higher rates usually in accordance with
a standing agreement between the employer and the workers. Hence, payment of
overtime consists of two elements, the normal wages i.e., the usual amount, and
the extra payment i.e., the premium. This amount of extra payment paid to a worker
under overtime is known as overtime premium.
The overtime payment affects the productivity and cost in many ways as follows:
(i) During overtime period the efficiency of a worker is low. This causes reduced
productivity, thus during this period the productivity is lesser than the normal
one.
(ii) In their anxiety to earn more, the workers may not concentrate on work during
normal time and thus the output during normal hours may also fall.
(iii) The practice of resorting to overtime adversely affects workers’ health which may
lead to increase in accident rate and consequently a decrease in productivity.

166
 INTER CA. – COSTING

(iv) Due to overtime, it is not possible to carry out necessary maintenance of plants
and machinery. Such a situation results occasionally in a major breakdown and
hence accounts for the stoppage of production cycle.
(v) Reduced output and increased premium are responsible for bringing an increase
in cost of production.

Overtime premium is a part of total wages of overtime period. In cost accounting

the treatment of overtime premium will be as follows:
(i) If the overtime is resorted to at the desire of the customer, then the entire
amount of overtime including overtime premium should be charged to the job
directly.
(ii) If it is due to a general pressure of work to increase the output, the premium as
well as overtime wages may be charged to general overheads.
(iii) If it is due to the negligence or delay of workers of a particular department, it
may be charged to the concerned department.
(iv) If it is due to circumstances beyond control, it may be charged to Costing Profit
& Loss Account.

As regards the control of overtimes is concerned, it is difficult to eliminate it

completely. But it is not difficult to control it and to keep it to the barest minimum.
The procedure for control of overtime work involves the following steps :
1. Entire overtime work should be duly authorized after investigating the reasons
for it.
2. Overtime cost should be shown against the concerned department. Such a
practice should enable proper investigation and planning of production in
future.
3. If overtime is a regular feature, the necessity for recruiting more men and
adding a shift should be considered.
4. If overtime is due to lack of plant and machinery or other resources, steps may
be taken to install more machines, or to resort to sub-contracting

Question 6
The finishing shop of a company employs 60 direct workers. Each worker is paid ` 400 as
wages per week of 40 hours. When necessary, overtime is worked up to a maximum of
15 hours per week per worker at time rate plus one-half as premium. The current output
on an average is 6 units per man hour which may be regarded as standard output. If
bonus scheme is introduced, it is expected that the output will increase to 8 units per man
hour. The workers will, if necessary, continue to work overtime up to the specified limit
although no premium on incentives will be paid.
The company is considering introduction of either Halsey Scheme or Rowan Scheme of
wages incentive system. The budgeted weekly output is 19,200 units. The selling price is

IMPORTANT THEORY QUESTIONS FOR EXAMINATION

Question 1
Distinguish between Idle Time and Idle Facilities. How are they treated in Cost Accounts?
Develop a system of control for Idle Time in a factory.

Answer
Idle time: It refers to the labour time paid for but not utilised on production. Idle time
thus represents the time for which wages are paid but no output is obtained. This is the
period during which the workers remain idle. It arises due to various reasons. According to
reasons, idle time can be classified into normal idle time and abnormal idle time. Normal
idle time is the time which cannot be avoided or reduced in the normal course of business.
For example, some labour time is bound to be lost due to the time taken by workers to
cover the distance between the factory gate and the department or the actual work place
where they are working. Sometime also elapses between the finishing of one job and
the starting of another job. Since a worker cannot work continuously for the whole day,
sometime is required during which he attends to this personal needs, such as taking lunch
or rest to avoid normal fatigue. It is thus obvious that normal idle time is unavoidable.
Abnormal idle time may arise because of inefficiency, mischief and misfortune such as
breakdown of machines for a long period, power failure, non-availability of materials,
etc. generally, it is avoidable and controllable. However, abnormal idle time arising on
account of strike, lockouts, floods, etc. may be uncontrollable. By proper care and caution
abnormal idle time can be reduced or eliminated to a very great extent.
Idle facilities: The terms facilities has a wider connotation. It may include production
capacity as well. Facilities may be provided by the fixed assets such as building space,
plant/equipment capacity etc., or by various service functions such as material services,
production services, personnel services etc., if a firm is not able to make full use of all
these facilities then the firm may be said to have idle facilities. Thus, idle facilities refer
to that part of total production facilities available which remain unutilized due to any
reason such as non-availability of raw-material, etc. Idle facilities differ from idle time.
A firm may have idle facilities even when it works full time; e.g., when facilities have been
provided on too large a scale.
Treatment of idle time in Cost Accounting: Treatment of idle time in coast accounting depends
upon its nature. The cost of normal idle time is charged to the cost of production. This
may be done by inflating the labour rate or the normal idle time may be transferred to
factory overhead for absorption through factory overhead absorption rate. In relative

180
 INTER CA. – COSTING

terms, the cost of normal idle time is generally nominal. As against normal idle time
cost, the cost of abnormal idle time sometime may be quite substantial. Since these costs
are beyond the control of the management and being abnormal in nature, they do not
form part of cost of production. Therefore, payment for them is not included in cost of
production and is transferred to costing profit and loss account.
Treatment of idle facilities in Cost Accounting: Normal idle facilities cost which arises due
to unavoidable reasons, should be included in the works overhead. On the other hand,
abnormal idle facilities cost which arises due to plants or machines/facilities remaining
idle on account of trade depression or for want of work etc., should be written off to
costing profit and loss account.
System of controlling idle time: The system of idle time control aims at controlling the time
for which a worker has been paid but has not been utilised for productive purposes. Such
a loss of time is know as idle time. The control of idle time requires the use of a proper
system of recording the idle time, ascertaining its reasons for occurrence and initiating
suitable administrative action to stop its reoccurrence.
To record the duration of idle time and to ascertain the reasons of its occurrence, the
format given as below may be used. This format not only records the time paid for but
also the standard time which a worker should take to produce a unit of output. The
time actually paid on comparison with standard time may reveal the element of idle
time, if any. After this the reasons for the occurrence of idle time should be ascertained
and stated in the suitable column of the format. In this way a statement of labour time
utilization is usually prepared. Such a statement is quite useful to the officers who are
concerned with the control of idle time. In fact it serve as a sound basis for their actions
to control idle time. Such a statement clearly points out to persons responsible for the
control of idle time the reasons for the occurrence of idle time.
Finally, the concerned officer may suggest the remedial measures to minimize the
occurrence of idle time in future.

Question 2
What do you understand by Overtime Premium?
What is the affect of overtime payment on productivity and cost?
Discuss the treatment of overtime premium in cost accounts and suggest a procedure for
control of overtime work.

181
 INTER CA. – COSTING

Answer
Overtime premium: Overtime is the amount of wages paid for working beyond normal
working hours as specified by Factories Act or by a mutual agreement between the
workers union and the management. According to Factories Act of 1948, a worker is
entitled for overtime at double the rate of his wages (including allowances) if he works
beyond 9 hours in a day or 48 hours in a week even where the Act is not applicable, the
practice is to pay for overtime work at higher rates usually in accordance with a standing
agreement between the employer and the workers. Hence, payment of overtime consists
of two elements, the normal wages i.e., the usual amount, and the extra payment i.e.,
the premium. This amount of extra payment paid to a worker under overtime is known
as overtime premium.
The overtime payment affects the productivity and cost in many ways as follows :
(i) During overtime period the efficiency of a worker is low. This causes reduced
productivity, thus during this period the productivity is lesser than the normal one.
(ii) In their anxiety to earn more, the workers may not concentrate on work during
normal time and thus the output during normal hours may also fall.
(iii) The practice of resorting to overtime adversely affects workers’ health which may
lead to increase in accident rate and consequently a decrease in productivity.
(iv) Due to overtime, it is not possible to carry out necessary maintenance of plants and
machinery. Such a situation results occasionally in a major breakdown and hence
accounts for the stoppage of production cycle.
(v) Reduced output and increased premium are responsible for bringing an increase in
cost of production.
Overtime premium is a part of total wages of overtime period. In cost accounting the
treatment of overtime premium will be as follows:
(i) If the overtime is resorted to at the desire of the customer, then the entire amount
of overtime including overtime premium should be charged to the job directly.
(ii) If it is due to a general pressure of work to increase the output, the premium as well
as overtime wages may be charged to general overheads.
(iii) If it is due to the negligence or delay of workers of a particular department, it may
be charged to the concerned department.
(iv) If it is due to circumstances beyond control, it may be charged to Costing Profit &
Loss Account.
As regards the control of overtimes is concerned, it is difficult to eliminate it completely.
But it is not difficult to control it and to keep it to the barest minimum.
The procedure for control of overtime work involves the following steps :

182
 INTER CA. – COSTING

1. Entire overtime work should be duly authorized after investigating the reasons for it.
2. Overtime cost should be shown against the concerned department. Such a practice
should enable proper investigation and planning of production in future.
3. If overtime is a regular feature, the necessity for recruiting more men and adding a
shift should be considered.
4. If overtime is due to lack of plant and machinery or other resources, steps may be
taken to install more machines, or to resort to sub contracting.

Question 3
What are piece-rate? What advantage and disadvantages are attributed to their use?
What principles should govern the determination and revision of piece-rates?

Answer
Piece Rate: It is that rate, which is paid to a worker for producing a single unit of output.
The wages of a worker under piece rate method are calculated by multiplying the number
of units of output produced by a pre-determined piece rate. For example, if the pre-
determined piece rate is ` 5 per unit and a worker has produced 200 units, then the total
wages to be paid will be ` 1,000.
To be more exact, the above type of piece rate method is known as straight piece rate. It
has another variation also, which is known as differential piece rate. Under differential
piece rate system, different piece rates are given to workers for different levels of efficiency.
Important advantage and disadvantages which are attributed to the use of piece rates
are as follows:
Advantages of piece rates:
1. The application of piece rate acts as an incentive to workers to produce more to
maximize their earnings.
2. Due to increase in output, the per unit total cost of production reduces.
3. Losses due to mishandling of machines and breakage of tools etc., are minimized, as
the workers understand fully their importance.
4. Workers are constantly on the lookout to develop improved methods of performing
jobs which may result in increased productivity.
5. The piece rate method is easily understood by workers and thus it is highly appreciated.
6. The use of piece rates reduces supervision costs.
Disadvantages of piece rates:
1. To maximize earnings, sometime sub - standard quality of goods are produced by
workers.

183
 INTER CA. – COSTING

2. Workers hardly have any consideration for the resources of the concern. They may
waste material and mishandle tools and machinery. Such an act on the part of
workers reduces the concern’s profitability.
3. The use of piece rate has no place for less efficient workers.
4. Due to continuous working for several hours, the health of workers is adversely
affected.
5. The determination of a piece rate acceptable to workers is a difficult task. In fact, it
is a disputable point between employees and employer.
Important principles of piece rate determination and revision :
Important principles which should govern the determination and revision of piece rates
are as follows:
1. Different piece rates should be determined for different types of jobs.
2. The piece rates determination should give due consideration to factors such as
requirement of jobs, conditions under which jobs would be performed, risk involved,
efforts involved while working on the job, etc.
3. The wage rate should be such that it guarantees a minimum living wage to ensure
a satisfactory standard of living.
4. It should reduce/stabilize labour turnover on its application.
5. It should act as an incentive to motivate workers in giving a higher output.
6. The wage rate should be able to reduce absenteeism and late coming.
7. It should be acceptable to trade unions.
8. It should be flexible and capable of being adapted to changed circumstances.
9. Piece rates should be revised as and when they are revised by other firms in the
industry or there is an increase in the cost of living index.
10. It may be revised at the end of the contract period as settled between management
and workers union.

Question 4
List down the factors to be considered before introducing a scheme of incentive to workers.

Answer
An incentive can be defined as the stimulation of effort and effectiveness on the part of
workers by offering monetary inducement or enhanced facilities. It means that incentive
can be given in monetary or non - monetary form to workers. It is usually linked with
the efforts made by individual workers or by their work group for increasing production.
By the implementation of such a scheme not only the workers but also the employer is

184
 INTER CA. – COSTING

benefited. Due to increased production the overhead cost is spread over a larger output
and thus per unit cost of production of the product is reduced.
Factors to be considered before introducing a scheme of incentives to workers.
1. The impact of the Scheme in motivating workers.
2. The impact of the scheme on workers performing:
(i) Quality job and thus giving a lower output
(ii) Routine job with a potential to give a higher output.
(iii) Job by using an automatic machine, where the possibility of increasing the
output beyond the fixed number does not exist.
3. The reaction of workers and union leaders towards the incentive scheme.
4. How for it is practicable to measure the performance of each worker, as it is necessary
for the calculation of incentive?
5. The extent of saving in cost of production per unit due to increased production.
6. The incentive schemes prevailing in other areas and industries or similar business.
7. The effect of incentive scheme on different sets of workers e.g., unskilled and skilled
workers.
8. The exactitude with which standards of performance can be laid down. As it is
necessary for the introduction of a scheme of incentives.
9. The cost of operating the scheme.
10. The capacity of the market to absorb the increased production because of the scheme
without reducing the selling price.

Question 6
Discuss two types of Costs, which are associated with labour turnover.
 (Nov. 2003, 3 Marks)
Answer
Two types of costs associated with labour turnover are:
(i) Preventive costs : These costs are incurred to keep the labour turnover rate at a low
level. They include costs of accommodation, transport facilities, medical services,
welfare schemes, pension schemes, environment improvement, lighting, heating,
air-conditioning etc. The rate of labour turnover is usually low, if a company incurs
higher preventive costs.
(ii) Replacement costs : These costs arise due to high labour turnover, e.g. cost of advertising,
recruitment, selection, training & induction, abnormal breakage and scrap, extra
wages & overheads etc., caused as a result of inefficient and inexperienced newly
recruited workers.

Question 7
Discuss the accounting treatment of Idle time and overtime wages.
 (May 2003, 3 Marks)
Answer
Accounting treatment of idle time wages & overtime wages in cost accounts:
Normal idle time is treated as a part of the cost of production. Thus, in the case of direct
workers, an allowance for normal idle time is built into the labour cost rates. In the case
of indirect workers, normal idle time is spread over all the products or jobs through the
process of absorption of factory overheads.
Under Cost Accounting, the overtime premium is treated as follows :
• If overtime is resorted to at the desire of the customer, then the overtime premium
may be charged to the job directly.
• If overtime is required to cope with general production programme or for meeting
urgent orders, the overtime premium should be treated as overhead cost of particular
department or cost center which works overtime.
• Overtime worked on account of abnormal conditions should be charged to costing
Profit & Loss Account.
• If overtime is worked in a department due to the fault of another department the
overtime premium should be charged to the latter department.

186
 INTER CA. – COSTING

Question 8
Discuss the effect of overtime payment on productivity  (Nov. 2004, 3 Marks)

Answer
Effect of overtime payment on productivity: Overtime work should be resorted to only when
it is extremely essential because it involves extra cost. The overtime payment increases
the cost of production in the following ways:
1. The overtime premium paid is an extra payment in addition to the normal rate.
2. The efficiency of operators during overtime work may fall and thus output may be
less than normal output.
3. In order to earn more the workers may not concentrate on work during normal time
and thus the output during normal hours may also fall.
4. Reduced output and increased premium of overtime will bring about an increase
cost of production.

Question 9
State the circumstances in which time rate system of wage payment can be preferred in a
factory.  (Nov. 2004, 3 Marks)

Answer
Circumstances in which time rate system of wage payment can be preferred :
In the following circumstances the time rate system of wage payment is preferred in a
factory.
1. Persons whose services cannot be directly or tangibly measured, e.g., general helpers,
supervisory and clerical staff etc.
2. Workers engaged on highly skilled jobs or rendering skilled services, e.g., tool making,
inspection and testing.
3. Where the pace of output is independent of the operator, e.g., automatic chemical
plants.

Question 10
Discuss briefly, how will you deal with casual workers and workers employed on outdoor
work in Cost Accounts.  (May 2002, 4 Marks)

187
 INTER CA. – COSTING

Answer
Causal and outdoor workers
Casual workers (badli workers) are employed temporarily, for a short duration to cope
with sporadic increase in volume of work. If the permanent labour force is not sufficient to
cope effectively with a rush of work, additional labour (casual workers) are employed to
work for a short duration. Outdoor workers are those workers who do not carry out their
work in the factory premises. Such workers either carry out the assigned work in their
homes (e.g., knitwear, lamp shades) or at a site outside the factory.
Casual workers are engaged on a daily basis. Wages are paid to them either at the
end of the day’s work or after a periodic interval. Wages paid are charged as direct or
indirect labour cost depending on their identifiability with specific jobs, work orders, or
department.
Rigid control should be exercised over the out-workers especially with regard to following:
1. Reconciliation of materials drawn/issued from the store with the output.
2. Ensuring the completion of output during the stipulated time so as to meet
comfortably the orders and contracts.

BUDGETARY CONTROL

THEORY SECTION

FUNCTIONAL BUDGETS
1. Sales Budgets:
The end objective is to get the expected sale that the company plans to make. The
classification exclusively depends on the information given which can be in terms of
areas, managers, salesmen, period, the products, the quantity and price. Sometimes,
instead of giving the budgeted sales quantity and price, we may be given the actual
result of some other past period and the expected changes. In such case we give
effect to the expected changes, adjust the past accordingly and the resultant figures
would be the future targets.

2. Purchase and / or production budget for main product:

The following format should be used to develop this budget.
Budgeted sales quantity (a) XXXX
Add : Budgeted closing stock of main product (b) + XXXX
Less : Opening stock of main product (b) – XXXX
Quantity to be purchased / Net quantity to be produced (c) XXXX
Add : Loss of main product (c) + XXXX
Gross Quantity to be produced (d) XXXX
(a) The Budgeted Sales Quantity may be given straight away or budgeted sales
value and sales price may be given (in which case we divide budgeted sales
value by sales price) or instead of sales price the total cost and profit% may be
given in which case, we add the profit to the cost and get sales price or instead
of total cost we may be given details of cost, in which case we first develop cost
sheet and get the sales price. Exceptionally, sales budget may be required to
get total budgeted sales quantity.
(b) Most often these are straight away given in the problem. Sometimes stock
valuation and the cost at which the stock is valued may be given in which case

195
 INTER CA. – COSTING

we divide the stock valuation by cost per unit. Sometimes, instead of cost per
unit, we may be given details of cost so that we calculate cost by preparing
cost sheet.
(c) If the company is buying the main product, then it is Net quantity to the
purchased. If the purchase price is given, we may multiply this quantity by the
price to get total purchase cost.
If we manufacture the main product and there is no loss of the main product
(and not raw material), then, this quantity is the quantity to be manufactured.
If there is a possibility of loss of output, then, accordingly quantity likely to be
rejected must be added to this figure to get total budgeted production.
(d) It is possible that the production capacity available is insufficient. In that case,
upto the production capacity available, we manufacture (and that part of
the quantity becomes production budget) and the balance we buy (and that
quantity represents purchase budget).

3. Purchase and / or production budget for raw material (say raw material x) required for
main product.
The following format should be used to prepare this budget.
Budgeted raw material quantity required for
Production of main product (a) XX
Add : Budgeted Closing Stock of raw material + XX
Less : Opening Stock of raw material – XX
Net Qty. to be purchased / Net qty. to be produced XX
Add : Loss of output of raw material XX
Gross Quantity to be produced + XX
(a) This depends on the following three factors :
→ Various main products which require raw material 'X' as input (which would
always be given).
→ The quantity of each of main product to be produced (which will never be
given and therefore one has to prepare production budget first which itself
may require sales budget).
→ The quantity of each type of raw material required per unit of each of the
main production.
→ All other points (b, c) are, with appropriate changes, same as applicable
to production budget.

196
 INTER CA. – COSTING

4. Purchase / production budget for raw material (y) required to manufacture other raw
material (x) which is required for main product (z).
The format for this budget is the same as the one prepared for budget No. 3. However,
in budget No.3, we had written the raw material required for main product. Here
raw material 'X' becomes main product in relation to raw material 'y, other things
being the same.

5. Purchase budget for raw material (say B) required for other raw material (say Y).
In relation to this material, 'Y' becomes main product and accordingly, purchase
budget for raw material as written in part (3), should be prepared.
If the Question is only on this budget, then, we have to prepare following budgets in
the order given.
(1) Sales budget.
(2) Production budget for main product.
(3) Production budget for raw material X.
(4) Production budget for raw material Y.

6. Labour Cost Budget:

The end objective is to get the expected labour cost that we are going to incur.
The labour cost to be incurred would depend on whether the workers are paid
on time basis or piece-rate basis. If it is piece rate, then, we need to multiply the
budgeted production of each of the products (including raw material, if they are
being manufactured) by the piece rate p.u. As we have studied in Labour Cost Control
Chapter, the piece rate can be derived by dividing time wages for certain period of
time by normal output expected in that much period of time (obviously, after making
provision for normal permitted idle time).
If they are paid on time basis, then, we should first calculate number of hours for
each type of labour required by multiplying the number of units of each item to be
produced by no. of hours of each type of labour required per unit of each of the
products to be produced. The number of hours that we now get should be multiplied
by wage rate per hour to get budgeted labour cost.
It is quite possible that number of units of various items to be produced may not be
given. In that case, we should prepare sales budget and other production budgets
to get the quantity of each item to be produced.
7. Factory Overheads / Administrative overheads / S & D overheads budget:
Here the objective is to get the expected cost we are to incur. Most often expenses

197
 INTER CA. – COSTING

to be incurred are given but exceptionally we may have to follow the principles
applicable to overheads chapter which would require allocation, apportionment
and reapportionment.

8. Cash Budget:
This is opening balance (positive or negative) plus expected receipts minus expected
payments.

9. Master budget:
Master Budget is budgeted Profit & Loss Account and Budgeted Balance Sheet. It is
obvious that to prepare these two statements, all other mini budgets will have to
be prepared.

IMPORTANT THEORY QUESTIONS FOR EXAMINATION

Question 1
Explain briefly the concept of ‘flexible budget’.  (2 Marks, November 2008)

Answer
Flexible Budget: A flexible budget is defined as “a budget which, by recognizing the difference
between fixed, semi-variable and variable cost is designed to change in relation to the
level of activity attained”. A fixed budget, on the other hand is a budget which is designed
to remain unchanged irrespective of the level of activity actually attained. In a fixed
budgetary control, budgets are prepared for one level of activity whereas in a flexibility
budgetary control system, a series of budgets are prepared one for the each of a number
of alternative production levels or volumes. Flexible budgets represent the amount of
expense that is reasonably necessary to achieve each level of output specified. In other
words, the allowances given under flexibility budgetary control system serve as standards
of what costs should be at each level of output.

Question 2
Discuss the components of budgetary control system.  (2 Marks, May 2009)

Answer
Components of budgetary control system
The policy of a business for a defined period is represented by the master budget the
details of which are given in a number of individual budgets called functional budgets.
The functional budgets are broadly grouped under the following heads:
(a) Physical Budgets – Sales Qty, Product Qty., Inventory, Manpower budget.
(b) Cost Budgets – Manufacturing Cost, Administration Cost, sales & distribution cost, R
& D Cost.
(c) Profit Budget

Question 6
Describe the steps involved in the budgetary control technique.
 (4 Marks, November 2013)
Answer
There are certain steps involved in the budgetary control technique. They are as follows:
(i) Definition of Objectives: A budget being a plan for the achievement of certain
operational objectives, it is desirable that the same are defined precisely. The
objectives should be written out; the areas of control demarcated; and items of
revenue and expenditure to be covered by the budget stated.
(ii) Location of the key (or budget) factor: There is usually one factor (sometimes there
may be more than one) which sets a limit to the total activity. Such a factor is known
as key factor. For proper budgeting, it must be located and estimated properly.
(iii) Appointment of controller: Formulation of a budget usually required whole time
services of senior executive known as budget controller; he must be assisted in this
work by a Budget Committee, consisting of all the heads of department along with
the Managing Director as the Chairman.
(iv) Budget Manual: Effective budgetary planning relies on the provision of adequate
information which are contained in the budget manual. A budget manual is a
collection of documents that contains key information for those involved in the
planning process.
(v) Budget period: The period covered by a budget is known as budget period. The Budget
Committee determines the length of the budget period suitable for the business.
It may be months or quarters or such periods as coincide with period of trading
activity.
(vi) Standard of activity or output: For preparing budgets for the future, past statistics
cannot be completely relied upon, for the past usually represents a combination
of good and bad factors. Therefore, though results of the past should be studied
but these should only be applied when there is a likelihood of similar conditions
repeating in the future.

STANDARD COSTING

THEORY SECTION

(A) Brief Introduction:

In corporate sector, there is a separation of ownership from management. The
owners do not manage the business and the managers are not the owners. Even in
non-corporate sector, with gigantic business affairs, it is almost impossible for the
owners to manage the business themselves.
Accordingly, owners are compelled to delegate authority to the managers. Since the
managers have no proprietary interest in the business, it is quite possible that they
may tend to be inefficient and a bit careless and because of this, the sales may come
down, cost and rejection may increase resulting thereby in substantial loss of profit.
For this reason, the owners feel, and rightly so, that the performance of various
managers should be subjected to some degree of stringent control. There is a need
to follow carrot and stick approach.
Control always presupposes some yardstick or standard. Accordingly, well before
the period commences, detailed standards are laid down for various managers.
These standards clearly show what is expected of the concerned managers. For
example, in respect of sales, we lay down for sales manager, the types of products
to be sold, the quantity of each of them to be sold and the price to be charged. At
the end of the relevant period the actual results are compared with the expected
ones (the standards) and the difference, known as VARIANCE, is analysed to throw
light on the precise factors responsible for the variation. As far as the examination
is concerned, this is the end. In real life, further investigation is undertaken, if the
variance amount is very significant and corrective actions are taken so as to prevent
adverse past from repeating itself in future.
We apply Standard Costing technique to six areas in all.
They are as follows :
1. Material Cost
2. Labour Cost

209
 INTER CA. – COSTING

3. Variable Overheads
4. Fixed Overheads
5. Sales
6. Profit

(B) EXPLANATION OF THE METHOD FOLLOWED IN THE SOLUTIONS:

1. MATERIAL COST VARIANCES:
The following is the chart of the material cost variances
Total Material
Cost Variance

Material Price Material Usage Variance

Variance

Material Cost Material Yield / Quantity /

Variance Sub - usage Variances
Check
Total Material Cost Variance = Material Price Variance + Material usage Variance
Material Usage Variance = Material Mix Variance + Material Yield Variance

Detailed Explanation:
(i) Setting the standards:
As we saw, the actual results are to be compared with the Standards and for
this purpose, we must have comparable Standards.
The material cost is a variable cost item and the amount of cost that one incurs
entirely depends on the quantity of output. Thus, if the standard material cost
per unit is ` 5, and if the actual output is 100 units, then, the standard cost is
` 500. In other words in the case of material cost, the standards are always for the
actual output. If the production manager has produced, say, 1000 units, then we
should find out the cost that he should have incurred for 1000 units and this
cost should be compared with the actual cost to get the variance.
EXAMPLE:
Standards for 1 unit of product X :
Material Quantity Price per Kg. Total Cost (`)
A 5 Kgs. 2 10

210
 INTER CA. – COSTING

B 10 Kgs 3 30
15 Kgs. 40

The production manager has produced 1000 units and incurred the cost as
shown below.
Material Quantity Price per Kg. Total Cost (`)
A 4800 Kgs. 2.5 12,000
B 10600 Kgs. 2.9 30,740
15,400 42,740
Very obviously, the given standards which are for the output level of 1 unit
(` 40) can't be compared with the actual for 1000 units (` 42,740). The given
standards are to be revised to make them represent actual output level, so
that they become comparable.
This process of revising the standards is extremely simple. Since the cost is
variable in nature, the quantity figures and therefore the total cost figures
are just to be revised proportionately. For example, 1 unit of X needs 5 Kgs. of
Material A and therefore 1000 units should need 5000 Kgs. of material A. The
revised standard are shown below.
Material Quantity Price per Kg. Total Cost (`)
A 5000 2 10,000
B 10,000 3 30,000
15,000 40,000
In order to solve the problem, one should first pick up the information about the
output level represented by the given Standards. One should, then pick up the
actual output figure. If these two are same, then they are comparable and one
should proceed further to calculate the variances. If they are not same, then
given the Standards are to be proportionately revised to make them represent
actual output level. Thus, whether the given Standards need to be revised or not
depends on whether the output levels are same or not.

(ii) Calculation of Variances:

Total Material Cost Variance :
This variance shows the total loss or gain because of change in the total material
cost. The variance is the difference between the total Standard material cost
(obviously for actual output) and the total actual material cost.
Thus Material Cost Variance is :

211
 INTER CA. – COSTING

Total Std. Material Cost - Total Actual Material Cost

Material Price Variance : (see also notes on Single / Partial Plans)
This variance accounts for that part of the total material cost variance which
comes into being because of change in the material purchase price. Here, our
aim is to know the total gain or loss because of change in the material purchase
price.
The loss / gain per unit purchased and consumed can be calculated by simply
comparing standard purchase price with the actual purchase price. However,
we want to know the total gain or loss. The total loss / gain depends on the
actual quantity purchased and consumed.
Thus the price variance is :
Actual Quantity X (Standard Price - Actual Price)
Material Usage Variance :
This variance accounts for that part of the total material cost variance which
comes into being because of change in the consumption of raw material.
Here, our aim is to know the total gain/loss because of the difference between
material quantity consumed and the material quantity that should have been
consumed.
Obviously, therefore, we have to compare the standard material quantity with
the actual material quantity, the difference being the quantity of material lost
or gained. In order to quantify this loss in money terms, we need to multiply
this difference by the price of raw material.

We have two prices: Standard Price and the Actual Price.

Which price should be used?
We have to use standard price for this. This is based on the following reasons.
It is possible that there is some difference between the standard price and the actual
price. However, it is the job of the price variance to take care of that difference and
once that is taken care of, we are left with standard price alone. The difference
between the two prices always gets transferred to profit & loss account.
In the organisation, there is division of labour. For change in the price, purchase
manager is answerable whereas for change in the consumption of raw material,
production manager is accountable. Now, if we multiply the quantity difference by
the actual price, then the efficiency or otherwise of the purchase manager would
affect the variance for the production manager. The price, therefore, has to remain
constant and only Standard price remains constant.

212
 INTER CA. – COSTING

The standards are developed well before the period commences and we let our
production manager know the quantity of raw material that he should consume
and in case the actual consumption is more (or less) then we also let him know the
rate at which the penalty, or reward, will be calculated. That means the price has
to be known to the production manager well before the budget period commences.
Obviously only the standard price can be known in advance.

Thus the usage Variance is :
Standard material price X (standard raw material quantity-actual raw material quantity)
Material Mix Variance and Material Yield Variance
These two variances, put together account for the total material usage variance. If
the raw material consumed is not same as standard, then, that could be because
of two reasons in all. Either the mix of the input may change and/or the absolute
quantity of material may change. Consider the following example
Material Standard Quantity Actual Quantity
(1) (2) (3)
X 50 Kgs 40 55 55
Y 50 Kgs 60 55 60
Total 100 Kgs. 100 110 115

As can be seen, in the first case, though the total input quantity is same as the
standard, 10Kgs. of Y have replaced 10Kgs. of X. Thus, total quantity remaining
same, the mix of input has changed. In the second case, though the mix of input
items (1:1) has remained the same as the standard mix, the absolute quantity has
gone up by 10Kgs. Thus, mix remaining constant, this time the actual quantity has
changed. In the third case, the mix and the absolute quantity, both, have changed.
In other words, change in the mix and / or change in the quantity account for total
material usage variance. For the purpose of calculation of these variances, each
of them is to be calculated by keeping the other of them constant. Thus, when we
speak about the mix variance, we presume that the quantity consumed is quite upto
the mark and when we take-up yield variance, we presume that the mix is quite
upto the mark.
Material Mix Variance:
Here our aim is to know whether the actual input of raw materials is as per standard
or has changed. For this, we pick up the figure of total actual input and we apply the
standard mix ratio to it and we get the mix that ought to be, given the actual input.

213
 INTER CA. – COSTING

We compare this standard mix with the actual mix and multiply the difference by the
standard material price.
Thus material mix variance is:
Std. Material Price x (Std. Material Mix Quantity for Actual Input - Actual Mix
Quantity)
Material Yield Variance:
This variance accounts for that part of the usage variance that comes into being
because of change in the quantity of raw material consumed, the mix remaining
constant. There are four methods for the calculation of this variance, as shown
below:
1. Based on Input:
We just compare the total standard input quantity with the total actual input
quantity and we multiply the difference by the standard average cost. The
standard average cost is the total standard cost divided by the total standard
input quantity.
Thus Material Yield Variance is:
Std. Weighted Average Cost P.U. of Input x (Total Std. Input - Total Actual Input)
2. Based on process loss.
Based on the actual input quantity, we find out the Standard process loss and
we compare that with the actual process loss. The difference is output lost /
gained because of excess / less rejection. We multiply this difference by the
Standard average cost per unit of output.
Std. Average Cost P.U. of Output x (Std. Loss for Actual Input - Actual Loss)
3. Based on yield / output :
Based on the actual input quantity, we find out the Standard output and we
compare that with the actual output. The difference is the output lost / gained.
We multiply this difference by the Standard average cost per unit of output.
Std. Average Cost P.U. of Output x (Std. Output for Actual Input - Actual Output)
4. Based on mix:
This time we compare the Standard mix of standard input with the Standard
mix based on actual input (developed for the purpose of mix variance) and we
multiply the difference by the Standard price of relevant material item.
Std. Material Price x (Std. Mix for Std. Input - Std. Mix for Actual Input)

2. LABOUR COST VARIANCE:

The following is the chart of the labour cost variances :

TOTAL LABOUR COST VARIANCE

Rate of Pay Variance Labour Efficiency Variance

OR OR
Wage Rate Variance (Labour Time Variance)

Idle Time Variance Labour Mix Variance Labour Yield OR

OR quantity
Gang Competition OR sub Efficiency
Variance Variance
Check:
Total Labour Cost Variance = Rate of Pay Variance + Labour Efficiency Variance
Labour Time Variance = Idle Time Variance + Mix Variance +Sub Efficiency Variance

Detailed Explanation
(i) Setting the Standard :
Like Material cost, even this cost is also a variable cost item and therefore, like
material cost, here also the Standards are to be for actual output. This means if
the given Standards for labour cost do not represent actual output level, then,
they must be proportionately revised to make them represent actual output
level.
(ii) Calculation of variances :
The variance chart here almost resembles material variance chart with minor
changes. In most of the cases the cost changes from material to labour and
the variances are same. Accordingly, the explanations provided in respect of
material cost variances is equally applicable to labour cost variances and
therefore these details are not repeated.
Total Labour Cost Variance :
This variance is the difference between the total Standard labour Cost (for
actual output) and total actual labour cost.

215
 INTER CA. – COSTING

Thus Labour Cost Variance is :

Total Std. Labour Cost - Total Actual Labour Cost
Rate of Pay Variance :
This is just like material price variance. The Variance is actual number of hours
paid for multiplied by the wage rate difference.
In other words, it is :
Actual Hours X (Standard Rate - Actual Rate)
Labour Efficiency Variance :
This is just like material usage variance. The variance is Standard wage rate
multiplied by the difference between Standard hours and actual hours paid for.
Thus Labour Efficiency Variance is :
(Std. Hours - Actual Hours) x Standard Rate
Idle time Variance : This is abnormal idle hours for various categories multiplied
by applicable standard wage rates If there are two or more categories, then
category wise break-up of idle time would, normally, be given. If not given, we
must put presumption to get the break up. Preferably, the presumption should
be that idle hours were in standard ratio.
Thus Idle Time Variance is :
Idle Time x Standard Rate
Labour Mix Variance :
This is just like material mix variance. Thus, we apply the Standard mix ratio
to the actual input of hours worked and we get Standard mix for actual total
hours. If there is idle time, it should be deducted from the gross input hours and
the Standard ratio should be applied to the actual or productive hours paid for. This
is because, out of gross hours, Idle time variance accounts for idle hours.
Therefore, we now have to account for net hours worked.
Thus Labour Mix Variance is :
[Std. Mix for Actual Net Hours - Actual Mix (Net)] x Std. Rate Per Hour
Labour Sub Efficiency Variance :
This is just like material yield variance based on input. We compare total
standard hours with the total actual (but net i.e. excluding idle time) input
hours and we multiply the difference by Standard average rate per hour (Total
Standard Cost = Standard input hours)
Thus Labour Sub Efficiency Variance is :
(Total Std. Hours - Total Actual Net Hours) x Std. Weighted Average per hour

3. FIXED FACTORY OVERHEADS VARIANCES: (BASED ON ABSORPTION COSTING) :

The following is the chart of the fixed factory overheads cost variances under
absorption costing:
TOTAL FIXED OVERHEADS COST VARIANCE

Fixed Overheads Expenditure Volume

Budget Variance

Calendar Capacity Idle Time Idle Time

Check:
Total Cost Variance = Expenditure Variance + Volume Variance
Volume Variance = Calendar Variance + Capacity Variance + Idle item Variance +
Efficiency Variance.
Detailed Explanation :
(i) Setting the Standards :
Unlike the Raw Material Cost, this cost does not depend on the output. Rather,
it depends on the period because it is a period cost. Obviously, therefore, the
standards or, say budgets, are always for a period. Very soon we shall see that
for calculating variances, we sometimes compare days, hours, expenditure and
output figures for the given period and therefore we should know budgets as
regards these items.
(ii) Basic explanation about fixed overheads variances :
For setting the selling price of a product, we generally add profit margin to
the total cost. The total cost is the sum total of variable cost and fixed cost.
Variable cost per unit is reasonably simple to get because it depends on the
output. However, the fixed cost has nothing to do with the output, and the
total cost remains constant irrespective of the quantity of the product that we
produce. Then, how do we get the fixed cost per unit?
For this, we have a system of recovering the overheads. Well before the budget
period commences, we make an estimate as regards fixed overheads to be
incurred and the quantity of the product to be produced Though there is no
nexus between the cost and the output, after all the output that we are going
to have, must bear the charge of overheads cost that we are going to incur.
Thus, we lay down nexus between the two and divide the budgeted overheads

217
 INTER CA. – COSTING

by the expected output and we get overheads per unit.

Once, we get the Fixed Overheads rate per unit, every time we produce a unit
we charge the overheads at this predetermined rate. If everything goes as per
our expectation, then, we notice at the end of the period that overhead amount
charged to the output is exactly equal to the overheads cost incurred and thus,
there is no variance. In other words, the overheads cost variance comes into
being if the overheads charged or, say, recovered are not some as overheads
incurred.
(iii) Calculation of variances :
Fixed Overheads Cost Variances :
This variance comes into being if there is some difference between overheads
recovered (obviously, on the basis of actual output) and overheads cost incurred.
Thus, this variance is under or over-absorption of overheads.
Consider the following example:
Budget Actuals
A B C D
Fixed Overheads ` 1,00,000 1,00,000 90,000 1,10,000 96,000
Output (units) 25,000 24,000 25,000 24,000 24,000
Absorption rate per `4
unit

In situation A, the amount recovered is ` 96,000 (24,000 X 4) whereas amount spent is

1,00,000. The amount spent is more which means there is under-recovery of overheads
and the variance comes into being. Here, whereas Fixed overheads, have remained
constant, the output has changed. In situation B, the amount recovered is ` 1,00,000
whereas amount spent is ` 90,000. There is over-recovery of overheads and the variance
comes into being. Here, whereas output has remained the same, the overheads have
changed.
In situation C, the amount recovered is ` 96,000 whereas the amount spent is ` 1,10,000.
Again, there is under recovery of overheads. This time overheads and output, both, have
changed but not proportionately.
In situation D, though overheads and output, both, have changed, there is still no variance
because the amount spent (` 96,000) and the amount recovered (24,000 X 4) are same.
This should suggest that the total overheads cost variance comes into being, if either
only overheads change, output remaining constant, or only output changes, overheads
remaining constant, or both of them change, but not in the due proportion. Under-

218
 INTER CA. – COSTING

absorption implies that the actual fixed overheads cost per unit is more than the standard
cost whereas over-absorption implies that the actual fixed overheads cost per unit is less
than the standard cost. Absence of under / over absorption implies that the actual fixed
overheads cost, per unit is same as standard cost. Accordingly, under-absorption is an
adverse variance whereas over absorption is a favourable variance.
In other words, if output and overheads, both remain constant or both of them change
but just in due proportion, then, there is no overheads cost variance at all.
To conclude, one should compare the amount of overheads recovered with the amount of
overheads spent and the difference is the variance. Over-recovery signifies the favourable
variance whereas under recovery signifies the adverse variance.
Thus Fixed Overheads Cost Variance is :
Fixed Overheads Absorbed - Actual Fixed Overheads
Fixed Overheads Expenditure Variance :
Just compare budgeted overheads with the actual amount spent and the difference is the
variance.
Thus Fixed Overheads Expenditure Variance = Budgeted Fixed Overheads - Actual Fixed
Overheads
Fixed Overheads Volume Variance :
We just compare the volume or the output figures and the difference is to be multiplied
by the recovery rate per unit. If the actual output is more than the budgeted output, the
variance is favourable (because higher output reduces the overheads cost per unit) and if
the actual output is less, the variance is adverse.
Thus Fixed Overheads Volume Variance is :
(Budgeted Output - Actual Output) x Absorption Rate P.U.
The analysis of volume variance is required to know the precise factors responsible for
change in the output. The output depends on so many factors like number of working
days, number of hours in working days, unproductive (idle) time and efficiency level.
Consider the following budget:
No. of days 250
Hours per day 500
Hours per unit 5
∴ Total Hours p.a. 1,25,000
∴ Total output p.a. 25,000
Calendar Variance
Now if, instead of working for 250 days, the workers work for 251 days, then, other
factors remaining constant, hours would increase by 500 and the output would increase

219
 INTER CA. – COSTING

by 100. The variance that comes into being because of change in number of days is called
calendar Variance. We should compare the number of days as per budget with actual
number of days and the difference should be multiplied by the recovery rate per day. If
the actual number of days is more, then, the variance is favourable because the more the
days, the more the hours and the more the output.
Thus Calendar Variance is :
(Budgeted Days - Actual Days) x Absorption Rate Per Day
Capacity Variance
Now, days remaining constant, if the workers work for more or less than 500 hours per
day, then, again the output would change. The variance that comes into being because of
change in such capacity utilization is known as capacity Variance. We find out the number
of hours that should have been paid for in actual number of days and we compare this
with the actual number of hours paid for. The difference is multiplied by the recovery rate
per hour. If the actual number of hours is more, then, the resultant variance is favourable
because the more the hours, the more the output.
Capacity Variance = (Std. hours for Actual Days - Actual Hours)
Absorption Rate per Hour
Sometimes in the problem, the student is not given information about number of days. In such
cases, the calendar variance cannot be calculated. Even the capacity variance, in the manner
shown above, cannot be calculated. In such cases, we compare budgeted hours with actual hours
paid for. The difference is to be multiplied by the recovery rate per hour. This comparison takes
care of calendar and capacity both. Therefore, if the information about days is not given, then,
we calculate this variance and call it capacity variance. If the information about days is given,
then we calculate calendar variance and capacity variance in a normal way but we use this
variance (direct comparison of hour) as crosscheck. This variance has to be equal to calendar
variance plus capacity variance.
If No. of Days are not given
Capacity Variance = Budgeted hours - Actual hours) Absorption per hour Rate
Capacity Variance by Alternate Method = Calendar Variance + Capacity
Variance by Normal Method
The idle time variance is calculated by multiplying idle hours by recovery
rate per hour.
Idle Time Variance = Idle Time x Absorption Rate per hour
The Efficiency Variance can be calculated in one of the two possible
ways, as shown below:

220

4. VARIABLE FACTORY OVERHEADS VARIANCES :

The following is the chart showing variable factory overheads variances.

TOTAL VARIABLE OVERHEADS COST VARIANCE

Variable Overhead Variable Overhead

Spending ./ Budget OR Spending ./ Budget OR
Expenditure Variance Expenditure Variance

Check :
Total Variable Overheads Cost Variance = Spending Variance + Utilization Variance
Detailed Explanation :
i) Setting the Standards :
This cost, being variable in nature, depends on the actual output and therefore,
like material cost and labour cost, the Standards are always for actual output.
ii) Calculation of Variances :
Total Variable Overheads Cost Variance :
This is the difference between total Standard Variable Cost and total actual
variable cost.
Variable Overheads Cost Variance = Total Standard Cost - Total Actual Cost
Variable Overheads Spending Variance :
This is just like labour rate of pay variance. Thus, we multiply the rate difference
by the actual labour hours paid for.
Variable Overheads Spending Variance = (Standard Rate - Actual Rate) Actual
hours
Variable Overheads Utilization Variance :
This is just like labour time variance. Thus, we multiply the labour hours
difference by the standard variable overheads rate per hour.
Variable Overheads Utilisation Variance = (Standard Hours - Actual Hours)
Standard Rate
Here, the actual no. of hours to be used should be gross no. of hours if the
variable overheads cost is incurred during the idle time. if it is not incurred
during the idle time, then, we should use net no. of hours.

223
 INTER CA. – COSTING

Note:
Though the analysis of Variable Overheads Cost Variance, as explained above is
possible, normally people calculate only the total variable overheads cost variance.
The other variances are not calculated normally. There are some obvious reasons for
this. The Spending Variance is rarely controllable. (Example: Increase in the electricity
rate) The Utilization variance comes into being if workers take more or less time and
this factor is looked into when we calculate labour time variance. There is no point,
in real life situation, in repeating the investigation. Thus, once workers take more
time, variable overheads utilization also increases. Therefore, the people are not
interested in analysing the total variable overheads cost variance.
It may also be noted that labour hours are common for labour cost variances and
variable overheads cost variance.

5) SALES VARIANCES :
The chart is as shown below :

TOTAL SALES VALUE VARIANCE

Sales Price Variance Sales Price Variance

Sales Mix Variance Sales Qty. / Sub - Volume Variance

Market Share Variance Market Size Variance

NOTES:
1) Budget for Comparison : The sales targets are always for a period. The budget to
be compared with the actual result has to be for the same period for which the
actual results are given. Thus, whenever the budget is for the same period for
which the actual results are given, the given budget itself is comparable with
the actual and no revision is required. On the other hand, if the budget is not
for the same period for which the actual results are given, the given budget
has to be revised to make it represent the same period for which the actual
results are given. Since we are talking about revenue and not the expenses, it

224
 INTER CA. – COSTING

is obvious that if actual quantity or price is mroe than the budget, then it gives
us favourable variance.
2) Total sales value variance : This is the difference between the budgeted sales and
the actual sales.
Total Sales Value Variance = Total Budgeted Sales - Total Actual Sales
3) Sales Price variance : This is just like material price variance and we get it by
multiplying the sales price difference by actual quantity sold.
Sales Price Variance = (Standard Sales Price - Actual Sales Price) x Actual Sales
Quantity
4) Volume Variance : This is just like material usage variance and we get it by
multiplying the sales quantity difference of each product by standard selling
price.
Sales Volume Variance = (Budgeted Sales Qty. - Actual Sales Qty.) x Standard
Sales Price
5) Sales Mix Variance : This is very usual mix variance. Accordingly, we apply
standard ratio to the actual total quantity sold and we develop standard sales
mix.
We compare this with the actual sales mix and the difference is to be multiplied
by standard selling price of each product.
Sales Mix Variance = (Standard Sales Mix for Actual Total Sales Qty. - Actual
Sales mix) x Std. S.P.
6) Sales Qty./Sub-Volume Variance : This is just like material yield variance based
on input and we get it by multiplying the total sales quantity difference by the
standard average selling price per unit.
Sales Qty. Variance = (Total Std. Sales Qty. - Total Actual Sales Qty.) x Std.
Weighted Avg. Sales Price p.u.
7) Market Share Variance : This is the change in total sales quantity due to change
in market share. We multiply the actual market size by standard market share
percentage to get standard sales quantity figure. We compare this with actual
sales quantity and multiply the difference by standard average sales price per
unit.
Market Share Variancce = Change in Sales Qty. due to charge in Mkt. Share x
Std. Weighted Avg. S.P.P.U.
8) Market Size Variance : This is the change in total Sales quantity due to change
in market size, multiplied by standard average sales per unit. We multiply the
market size difference by standard market share percentage to get the change

225
 INTER CA. – COSTING

in total sales quantity.

Market SIze Variance = Change in Sales Qty. due to Change in Mkt. Size x Std.
Weighted Avg. S.P.P.U.
PROFIT VARIANCES
The Chart is as shown on the last page of notes on this chapter.

NOTES:
1) Like Sales, the profit targets are also for the period and whenever the given
budget is not for the same period for which the actuals are given, the given
budget has to be revised. Also, the actual profit being more would be a favorable
variance.
2) Total Profit Variance :
This is the difference between total budgeted profit and actual profit.
(A) Profit Variance due to change in Sales :
This part of the chart is very similar to sales value variance chart. The only
difference being the sales quantity difference is to be multiplied by standard
sales price in sales value chart whereas the same quantity difference is to be
multiplied by standard profit per unit in this part of the chart. The quantity
variances in the two charts would be different only because of the difference
between standard sales price and standard profit. The sales price variance in
both charts is the same.
(i) Profit Variance due to change in S.P.
This is usual price variance which we get by multiplying actual sales quantity
by the sales price difference.
(ii) Profit Variance due to change in sales volume:
We get this variance by multiplying the sales quantity difference of each product
by the standard profit per unit.
(iii) Profit Variance due to change in Sales Mix :
This is usual mix variance and we get it by multiplying standard profit by the
mix difference.
(iv) Profit Variance due to change in Sales Qty.
This is usual quantity variance and we get it by multiplying the total sales
quantity difference by standard average profit per unit.
(a) / (b) : These Variances are same as those in the sales chart, the only difference
being, we multiply the quantity difference by standard average net profit per
unit.

226
 INTER CA. – COSTING

(B) Profit Variance due to change in Cost :

If only the total standard cost and actual cost per unit are given without
breakup into material cost, labour cost etc., then we calculate only the total
variance in the same way as we calculate sales price variance. Thus, we get it
my multiplying the cost difference by the actual quantity Produced per unit.
If the break-up of cost is given then all variances in respect of each cost item
are to be calculated by following usual principles applicable to a particular
cost item.
(i) Change in Material Cost :
These are usual material cost variances and we compare the standards for
actual output with the actuals and get normal Material Cost Variances.
(ii) Change in labour Cost :
We follow usual principles applicable to labour cost variacnes and get the
normal variances.
(iii) Change in Variable Cost :
We follow usual principles applicable to Variable Overheads cost Variances
and get the normal variances.
(iv) Change in Fixed Overheads Cost :
We follow usual principles applicable to Fixed overheads cost variances and
get the normal Variances.
(v) Change in Administration / Fixed S & D overheads : (under financial accounting)
As regards fixed expenses, we calculate only one variance which is Fixed
Overheads expenditure variance. We calculate the same by comparing budgeted
fixed overheads with actual Fixed Overheads. It should be noted that whereas
Fixed production overheads cost variance is to be analysed into expenditure
and volume variance, under absorption costing, the admn. and S & D fixed
cost variance is only in respect of expenditure and there is nothing like volume
variance here.
Under marginal costing, there would be only expenditure variance for all types
of fixed overheads.
If there is variable S & D overheads given then we develop the standards for
actual quantity sold and the standard S & D variable cost would be compared
with actual S & D cost to get Total variable S & D cost variance.

Valuation of raw material stock and calculation of price variance

There are two methods for accounting for variances and the stock valuation as well as
the calculation of price variance would depend on the method of accounting selected.
The methods are :
a) Single Plan
b) Partial Plan

A) Single Plan :
Under this method the price variance is based on actual quantity purchased and
accordingly the stock would be obviously valued at standard price. The usual stock
valuation methods like FIFO, LIFO, etc. have no relevance because the opening stock
and closing stock would both be valued at standard price.
In case the standards are revised, then the opening stock valuation would be revised
by valuing the quantity at revised standard price and the difference would be treated
as the price variance of the period in which the revision takes price.

B) Partial Plan :
Under this method, the price variance is based on actual quantity consumed and
accordingly, the stock has to be valued at actual purchase price.
If the opening stock is there, purchased at a price other than the current purchase
price, we need to follow FIFO or LIFO method for valuation of stock as well as
calculation of price variance.
If may be noted that revision of standards would not effect the opening stock
valuation because the opening stock is valued at actual price.

MARGINAL COSTING

THEORY SECTION

1. Absorption Costing v/s Marginal Costing:

Under adsorption costing, the fixed overheads (fixed production overheads under
financial accounting system and fixed production and administration overheads
under cost accounting system) are charged to the output. To the extent, the output
remains unsold i.e. closing stock, its valuation would include not only the variable
production cost but also the fixed overheads. This implies that part of the current
period's fixed cost is effectively converted into an asset and carried forward and
charged to the next period. Likewise the opening stock valuation also includes the
fixed overheads of previous period.
Unlike that, under marginal costing, the fixed overheads are all treated as period
cost items and are charged to the period rather than the output. Accordingly, the
stock valuation includes only the variable factory or production cost and not the
fixed charge.
For the normal accounting purposes, absorption costing is very widely accepted but
for management accounting purpose, it is only the marginal costing technique that
is to be used.
The profit and loss statement based on two different methods would give us two
different profit figures and the difference would be only because of stock valuation,
(difference in respect of opening and closing stock), and under cost accounting,
under/over absorption, if it is carried forward.
Incidentally it may also be noted that usual analysis of fixed overheads variance,
based on recovery, into expenditure variance, volume variance etc. presupposes that
the company follows absorption costing. If at all it is specifically given that the
company follows marginal costing then, the usual analysis is irrelevant and we
need to calculate only one variance i.e. fixed overheads expenditure variance.

236
 INTER CA. – COSTING

2. Absorption Costing: Limitations:

(i) Fixed cost treated as product cost.
(ii) Fixed cost is included in closing stock.
(iii) Entire fixed cost is not written off.
(iv) The more the production, the more the profit.

3. Marginal Costing: Advantages:

(i) Fixed cost treated as period cost.
(ii) Fixed cost is not included in closing stock.
(iii) Entire fixed cost is written off.
(iv) The more the sales, the more the profit.

4. Other chapters under Marginal Costing :

(i) Cost Sheet: Change in the form.
(ii) Reconciliation: Marginal: Fixed cost written off.
Absorption: Difference may be carried forward under cost accounting.
(iii) Overheads: Budgeted overheads not to be divided by budgeted level of activity.
(iv) Process Costing: Factory fixed overheads not to be debited to process account.
(v) Joint product / By product: Joint cost to be apportioned is joint variable factory
cost.
(vi) Integral / Non Integral: Factory fixed overhead/Fixed Admn. overhead to be
transferred to cost of sales a/c.
(vii) Budgetary control: Stock valuation to be divided by variable production cost
per unit.
(viii) Standard costing: Only expenditure variance (see part 4 for details)
(ix) Contract costing: Work not certified (WUC) not be include fixed cost.
(x) Operating costing
(xi) Material cost control No change
(xii) Labour cost control

5. Break-even analysis:
Vital presumptions:
This analysis, known as break-even analysis or contribution-margin analysis or cost
volume profit analysis is based on following three presumptions, it being used at
planning stage.
(i) Sales price per unit always remains constant.

237
 INTER CA. – COSTING

(ii) The variable cost per unit always remains constant.

(iii) The fixed cost for the period always remains constant.
This means that the contribution would always be some fixed percentage of sales.
Also the contribution-minus fixed cost is net profit just as contribution minus net
profit is fixed cost or fixed cost plus net profit is equal to contribution.

6. Break even point:

This is financial break-even point. It is the level of sales required to get no loss
and no profit situation. In other words, it is the level of sales that gives us the
contribution which is exactly equal to the amount of fixed cost.
To get the break-even point, we need to know the amount of fixed cost and the
relationship between sales and contribution (known as profit/volume ratio). Amount
of fixed cost is the amount of contribution required and the P/v ratio is the rate at
which contribution will be earned. By using these two, we can easily calculate break-
even point. The break-even point can be expressed in terms of value or volume.

7. Profit-Volume ratio :
This is the relationship between the sales and contribution. Everytime sales are
increased by ` 100 the contribution and therefore the net profit would increase by
the amount which is at the rate of P/v ratio. Likewise everytime sales of ` 100 are
lost, the contribution and therefore the net profit would be lost by the amount at
the rate of P/v ratio.

8. Margin of Safety :
This is the positive difference between the actual sales and the break even sales.
The more the amount of margin of safety the more should be the safety that the
company enjoys because, even if the sales fall by the amount of margin of safety,
the company still would not make the losses. Thus, it is Actual sales minus Break
even sales. This can be expressed in units or amount.

9. Margin of safety ratio :

This is margin of safety expressed as a percentage of the actual sales. Thus, it is
margin of safety divided by actual sales. It implies that even if sales fall by the
margin of safety percentage, the company still would be very safe in the sense that
it will not be making losses. Net profit devided by contribution also gives this ratio.

238
 INTER CA. – COSTING

10. General observations :

(i) If sales and contribution at any given point of time are known then, by using
the presumption that there is constant relationship between the two, we can
get P/v ratio by dividing contribution by sales.
(ii) If we have net profit of any two periods as also the sales of the same periods,
the difference between two profit figures would be nothing but the amount of
contribution, fixed cost remaining fixed, earned on sales which is the difference
between two sales figures. When we divide contribution difference by sales
difference, we get P/v ratio.
(iii) Fixed cost is contribution on break even sales and therefore if any two of break-
even sales, P/v ratio and fixed cost are given to us, the third one we can calculate
(e.g.. If we divide the fixed cost by the break even sales, we get the P/v ratio.).
(iv) Margin of safety is sales above the break even point and the contribution
earned above the break even point is net profit. In other words, net profit is
contribution on margin of safety and therefore, if we divide net profit by margin
of safety, we get the P/v ratio.
(v) Given the sales, P/v ratio and fixed cost, we can easily calculate the expected
net profit and likewise given the target net profit, fixed cost and P/v ratio, we
can easily calculate the sales required to meet the profit target. Similarly given
the sales, P/v ratio and the net profit, we can find out the expected fixed cost.
(vi) All observations written above are subject to the vital presumptions written in
note 5. Therefore, if the presumptions fails, then the calculations would have
to be changed accordingly.

11. Types of Break-Even Points :

(i) The usual break-even point where normal fixed cost is considered.
(ii) Cash Break-even point where only the cash fixed cost is considered.
(iii) Shut down point where only the additional fixed charge is considered.
(iv) Cost Break-even point.
(v) Profit Break-even-point.

12. Determination of Profitable Mix:

(a) When there is NO limiting factor:
The total fixed cost to be incurred remaining constant, the product which offers
more contribution per unit is more profitable product because it would maximise
the total contribution and therefore the net profit. Accordingly, calculate

239
 INTER CA. – COSTING

contribution per unit or the total contribution that each product makes and
the product which offers highest contribution will be taken as most profitable
one and so on. As long as the contribution per unit is positive, the product
is profitable. The product priorities and withdrawal of a product should be
decided on the basis of contribution that each product - offers and not the
net profit. If the demand for various products is of complementary nature,
then the total contribution based on various product combinations should be
considered. Also, if the fixed cost changes, as the product mix changes, then,
that should also be considered which means that the decision is based on
net profit. However, absorption costing should be completely ignored for such
decisions.
(b) When there is limiting factor:
Whenever some resources are required for products and are not adequately
available, these resources become limiting factor. Likewise, if demand is not
adequate, demand becomes limiting factor. If there are some limiting factors,
then the product which gives more contribution per unit may not give more
amount of total contribution because it may not make more profitable use of
the limited resources.
In such cases, we can calculate contribution per unit of limiting factor and
the product which offers more contribution per unit of limiting factor is to
be treated as more profitable product and the product priority order is to be
accordingly calculated. We divide the contribution per unit by the number of
units of limiting factor required per unit of the product. If one limiting factor
is on production side and the other on the sales side, then, we first calculate
contribution per unit of limiting factor on production side and we decide on the
product priority order. Keeping in mind that and the demand limitation of each
product, we make the allocation of limited resources to get the most profitable
product mix.
If there are two or more constraints on production side, then the most profitable
mix can be developed either by graphical method (if there are only two products)
or by simplex method (if we have three or more products).

IMPORTANT THEORY QUESTIONS FOR EXAMINATION

Question 1
Distinguish between: Marginal Costing and Differential Costing

Answer
Marginal Costing and Differential Costing
Marginal Costing is defined as the ‘Ascertainment of marginal costs and of the effect on
profit of changes in volume or type of output by differentiating between fixed costs and
variable costs’.
Differential Costing is defined as the technique of costing which uses differential costs
and / or differential revenues for ascertaining the acceptability of an alternative. The
technique may be termed as incremental costing when the difference is increase in costs
and decremental costing when the difference is decrease in costs. The main points of
distinction between marginal costing and differential costing are as below :
(a) The technique of marginal costing requires a clear distinction between variable costs
and fixed costs whereas no such distinction is made in the case of differential costing.
(b) In marginal costing, margin of contribution and contribution ratio are the main yard
sticks for performance evaluation and for decision making whereas under differential
costs analysis, differential costs are compared with the incremental or decremental
revenue (as the case may be) for arriving at a decision.
(c) Differential cost analysis is possible in both absorption costing and marginal costing,
where as marginal costing in itself is a distinct technique.
(d) Marginal cost may be incorporated in the cost accounting system whereas differential
costs are worked out separately.

Question 2
Explain and illustrate cash break-even chart.  (3 Marks, May 2008)

Answer
In cash break-even chart, only cash fixed costs are considered. Non-cash items like
depreciation etc. are excluded from the fixed cost for computation of break-even point.
It depicts the level of output or sales at which the sales revenue will equal to total cash
outflow.

249
 INTER CA. – COSTING

It is computed as under:

Sales

Total Cost
Sales and Cost
(`)
Cash Fixed Cost

Output

Hence for example suppose insurance has been paid on 1st January, 2006 till 31st
December, 2010 then this fixed cost will not be considered as a cash fixed cost for the
period 1st January, 2008 to 31st December, 2009.

Question 3
Elaborate the practical application of Marginal Costing.
 (4 Marks, November 2013)
Answer
Practical applications of Marginal costing:
(i) Pricing Policy: Since marginal cost per unit is constant from period to period, firm
decisions on pricing policy can be taken particularly in short term.
(ii) Decision Making: Marginal costing helps the management in taking a number
of business decisions like make or buy, discontinuance of a particular product,
replacement of machines, etc.
(iii) Ascertaining Realistic Profit: Under the marginal costing technique, the stock of
finished goods and work-in-progress are carried on marginal cost basis and the
fixed expenses are written off to profit and loss account as period cost. This shows
the true profit of the period.
(iv) Determination of production level: Marginal costing helps in the preparation of
break- even analysis which shows the effect of increasing or decreasing production
activity on the profitability of the company.

Question 4
What do you understand by Key factor? Give two examples of it.
 (2 Marks, May 2010)
Answer
Key factor is a factor which at a particular time or over a period limits the activities of an
undertaking. It may be the level of demand for the products or service or it may be the
shortage of one or more of the productive resources.
Examples of key factors are:
(a) Shortage of raw material. (d) Sales capacity available.
(b) Shortage of Labour. (e) Cash availability
(c) Plant capacity available.

Question 5
What is the meaning of Margin of Safety (MOS)? State the relationship between
Operating Leverage and Margin of Safety Ratio.(4 Marks, November 2013)

Answer
Margin of Safety (MoS) is the excess of total sales over the Break even sales. MoS defines
the amount upto which level sales can decline be fore occurring loss. Therefore

Break even sales (BE sales) will depend on contribution margin (BE sales = Fixed Cost ÷
Contribution margin). Contribution margin is related to operating leverage also. Operating
leverage is calculated as Contribution ÷ Operating profit and contribution margin plays
an important role in it. If sales are expected to increase, higher operating leverage will
result in higher profit. When sales are expected to decrease, lower operating leverage will
result in higher profit. Higher variable cost and lower fixed cost will result into higher MoS
and risk will be lower and vice versa.
So like Operating leverage, MoS is a measure of risk as to what extent an organisation is
exposed to change in sales volume.
