3.1 Introduction
Labour cost after material cost is another significant element of cost not only because the
wage bill in a modern organisation is generally substantial but also because it has certain
peculiar characteristics which other elements of cost do not have. A good cost accountant
must understand the special features of labour cost, the most important of which is that there
is almost no limit to the increase of output of this most important and wonderful factor of
production.
3.3.1 Important Factors for the Control of Labour Cost: To exercise an effective
control over the labour costs, the essential requisite is efficient utilisation of labour and allied
factors. The main points which need consideration for controlling labour costs are the
following:
(i) Assessment of manpower requirements.
(ii) Control over time-keeping and time-booking.
(iii) Time & Motion Study.
(iv) Control over idle time and overtime.
(v) Control over labour turnover.
(vi) Wage systems.
(vii) Incentive systems.
(viii) Systems of wage payment and incentives.
(ix) Control over casual, contract and other workers.
(x) Job Evaluation and Merit Rating.
(xi) Labour productivity.
3.3.2 Collection of Labour Costs: The task of collecting labour costs is performed by the
Cost Accounting Department which record separately wages paid to direct and indirect labour.
It is the duty of this department to ascertain the effective wages per hour in each department
and to analyse the total payment of wages of each department into:
(i) the amount included in the direct cost of goods produced or jobs completed;
(ii) the amount treated as indirect labour and thus included in overheads ; and
(iii) the amount treated as the cost of idle time and hence loss.
(iv) the amount treated as abnormal loss/ gain and to be transferred to profit and loss
account.
Through this process costs of various jobs are ascertained. Naturally, in this the proper
recording of time spent by the workers is essential. Labour cost per hour may be collected
through the use of the form given below:
A.B.C. Co. Ltd.

of workers so that workers may not have to wait for a long period for recording their time
of arrivals and departures.
7. A responsible officer should pay frequent visits at the factory gate to see that proper
method of recording of time is being followed.
Time-Booking - The clock card is required, essentially, for the correct determination of the
amount of wages due to a worker on the basis of time he has put in the factory.
It merely records day by day and period by period the total time spent by each individual worker in
the factory. But it does not show how that time was put to use in the factory—how an individual
worker utilised his time in completing jobs entrusted to him and how long he was kept waiting for
one reason or another due to lack of work, lack of material and supplies, lack of instructions,
machine breakdowns, power failures and the like. These are all vital pieces of information
necessary for the proper collection of cost data and for effective controlling of costs. For the
collection of all such information, a separate record, generally known as Time (or Job) card, is kept.
The time (or job) card can be of two types—
• One containing analysis of time with reference to each job : A separate job card is
employed in respect of a job undertaken; where a job involves several operations, a
separate entry is made in respect of each operation.
Thus the job card would record the total time spent on a particular job or operation. If a
number of people are engaged on the same job or operation, the time of all those
workers would be booked on the same card.
One advantage of this method is that it provides complete data on the labour content of
job or operation collectively so that the computation of labour cost is greatly facilitated.
But this method has drawbacks as well. Since a worker’s job timing is scattered over a
number of job cards the time spent on all these jobs and idle time must be abstracted
periodically for finding each worker’s total time spent on different jobs and the time for which
he remained idle during the period. The total of these two times (job and idle) must obviously
equal his total attendance time, as shown by his clock card or attendance register.
Thus, it would be seen that if the job cards are made out according to job or operation a
separate summary has to be prepared for reconciling each worker’s job and idle time with
his gate time. It would be quite obvious that such a reconciliation is of great importance
from the point of view of labour costs.
• The other with reference to each worker: In this case, it would greatly facilitate
reconciliation of the worker’s job time with his gate time.
Under this system, a card would be issued to each worker for each day or for each week
and the time which he spends on different jobs (and also any idle time) would be
recorded in the same card so that the card would have a complete history on it as to how
his time had been spent during the period. Since all the details would be on one card the
total time accounted for in the job card would be readily tallied with the total time put in
the Gate Card or attendance register. In this case however, a Labour Abstract for
different jobs would have to be prepared from the card of individual worker so that total
hours (and/or their value) put in by different workers on different jobs during the period
could be ascertained and aggregated. It would thus be seen that according to either of
the method a process of abstraction and reconciliation is necessary
Specimens of two types of job cards are given below:

Supervisor’s initial
how those hours have been put to use by the worker in his department, a job card must be
prepared to provide the necessary information. As we have already seen, the job card may be
prepared either worker-wise or job-wise.
Objectives of Time-Booking - Objectives of time-booking are as follows:
1. To ensure that time paid for, according to time keeping, has been properly utilised on
different jobs or work orders.
2. To ascertain the cost of each job or work order.
3. To provide a basis for the apportionment of overhead expenses over various jobs/work
orders when the method for the allocation of overhead depends upon time spent on
different jobs.
4. To calculate the amount of wages and bonus payable under the wage incentive system.
5. To ascertain the labour hours spent on each job and the idle labour hours.
3.4.2 Payroll procedure: Steps included in this process are as under:
2. Employee Details
Payroll Department
Statutory Bodies
Employees
(in case of piece rate) as reflected by the time keeping methods are sent to the
payroll department by the time keeping department. Further, payroll department
with the help of time booking records calculate any further incentives such as
overtime payment, bonus to be paid to the employees.
2. List of employees and other details: A list of employees on roll and the rate at
which they will be paid is sent by the personnel/ HR department. Payroll
department should ensure that no unauthorised person can paid.
3. Computation of wages and other incentives: Payroll department based on the
details provided by the time keeping department and personnel department
calculate wages/ salary to be paid to the employees. Payroll department prepares
pay slip for all employees authorized by the personnel department and forward the
same to the cost/ accounting department for further deductions and payment.
4. Payment to the employees: Cost/ accounting department deduct all statutory
deduction such as employee’s contribution to provident fund and employee state
insurance (ESI) scheme, TDS on salary etc. After all deductions wages/ salary is
paid to the employees.
5. Deposit of all statutory liabilities: All statutory deduction made from the employees
alongwith employer’s contributions such as provident fund and employee state
insurance scheme are paid to the respective statutory bodies.
6. Investigation: Should a clock card (attendance sheet) for an employee not listed on
the payroll sheet be found, investigation of its propriety is required. Likewise, there
should be an explanation for any missing clock cards deductions: After the gross
earnings (that is, the total amount earned by an employee before any deductions
are taken into consideration) have been calculated for every employee, deductions
are entered on the payroll sheet, and the net pay of each employee is determined.
The followings are generally deducted from the payroll

3.6 Overtime
Overtime premium: Work done beyond normal working hours is known as ‘overtime work’.
Overtime payment is the amount of wages paid for working beyond normal working hours. The
rate for overtime work is higher than the normal time rate; usually it is at double the normal
rates. The extra amount so paid over the normal rate is called overtime premium.
As per the Factories Act 1948 “ Where a worker works in a factory for more than nine
hours in any day or for more than fortyeight hours in any week, he shall, in respect of
overtime work, be entitled to wages at the rate of twice his ordinary rate of wages.”
Where any workers in a factory are paid on a piece-rate basis, the time rate shall be
deemed to be equivalent to the daily average of their full-time earnings for the days on
which they actually worked on the same or identical job during the month immediately
preceding the calendar month during which the overtime work was done, and such time
rates shall be deemed to be the ordinary rates of wages of those workers
Ordinary rate of wages means the basic wages plus such allowances, including the cash
equivalent of the advantage accruing through the concessional sale to workers of food
grains and other articles, as the worker is for the time being entitled to, but does not
include a bonus and wages for overtime work.
Occasional overtime is a healthy sign since it indicates that the firm has the optimum capacity
and that the capacity is being fully utilised. But persistent overtime is rather a bad sign
because it may indicate either (a) that the firm needs larger capacity in men and machines, or
(b) that men have got into the habit of postponing their ordinary work towards the evening so
that they can earn extra money in the form of overtime wages.
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 in costs
of production.
5. Gives rise to associated costs. (wear and tear of machinery, power etc.)
Steps for controlling overtime: To keep overtime to its minimum, it is necessary to exercise
proper control over the overtime work. The suitable procedure which may be adopted for
controlling overtime comprises the following steps:
1. Watch on the output during normal hours should be maintained to ensure that overtime is
not granted when normal output is not obtained during the normal hours, without any
special reasons.
2. Statement concerning overtime work be prepared along with justifications, at appropriate
places for putting up before the competent authority.
3. Prior sanction about overtime should be obtained from competent authority.
4. Actual rate of output produced during the overtime period should be compared with
normal rate of output.
5. Periodical reports on overtime wages should be sent to top management for taking
corrective action.
6. If possible an upper limit may be fixed for each category of workers in respect of
overtime.

Calculate the earnings of A and B from the following particulars for a month and allocate the
labour cost to each job X, Y and Z:

(iii) Contribution to provident Fund (on basic wages) 8% 8%
(iv) Contribution to Employee’s State Insurance (on basic wages) 2% 2%
(v) Overtime Hours 10
The normal working hours for the month are 200. Overtime is paid at double the total of
normal wages and dearness allowance. Employer’s contribution to state Insurance and
Provident Fund are at equal rates with employees contributions. The two workers were
employed on jobs X, Y and Z in the following proportions:

Illustration 6: (Calculation of workers recruited, joined and discharged)
The Cost Accountant of Y Ltd. has computed labour turnover rates for the quarter ended 31st
March, 2011 as 10%, 5% and 3% respectively under ‘Flux method’, ‘Replacement method’ and
‘Separation method’ respectively. If the number of workers replaced during that quarter is 30,
find out the number of:
(1) workers recruited and joined and (2) workers left and discharged.
Solution

No. of replacements
Labour turnover rate under replacement method = × 100
Average number of workers on roll

(1) Number of workers recruited and joined :
No. of separations * (S) + No. of accessions(A)
Labour turnover rate (Flux method) = × 100
Average number of workers on roll

Or =
100 600
⎡ 6000 ⎤
Or A = ⎢ 100 −18⎥ = 42
⎣ ⎦
No. of workers recruited and joined 42.
(2) Number of workers left and discharged :
No. of separations(S)
Labour turnover rate (Separation method) = × 100
Average number of workers on roll
3 S
=
100 600
Or S* = 18
Hence, number of workers left and discharged comes to 18.
(v) Effort of Workers: Whether the quantity of output is within the control of the worker and
if so, to what extent. Sometimes, as in the case of chain assembly work the output is not
dependent on the effort put in by workers; incentive schemes in such cases are not suit-
able.
(vi) Standards of Performance: The exactitude with which standards of performance can be
laid down. Fixation of standard is necessary for the introduction of a scheme of
incentives. When this requires heavy expenditure, incentive schemes may be rather
costly.
(vii) No Discrimination: The effect of an incentive scheme for one set of workers on other
workers. If for instance, an incentive scheme makes it possible for unskilled workers to
earn high wages, the wage rates for skilled workers must also be raised (if they are paid
on time basis) to avoid dissatisfaction among them. In that event, the incentive scheme
may raise labour cost instead of lowering it.
(viii) Comparative Study: The system of wage payment prevailing in other areas and
industries or similar occupations. If possible, there should be uniformity.
(ix) Attitude of Workers: The attitude of labour and trade unions towards incentive
schemes. Workers usually like to have a certain guaranteed time-basis wage but also like
to earn extra through an incentive scheme.
On the whole, the system of wage payment should be such as would increase production
without lowering quality. This will increase the surplus and will enable the employer to pay
higher wages which, in turn, will lead to higher output.
3.8.2 Main principles for a sound system of wage incentive: The objective of wage
incentives is to improve productivity and increase production so as to bring down the unit cost
of production.
In order to make the incentive scheme effective and useful, the following general principles
have to be considered while designing a sound system of wage incentives.
(i) Just and Fair: The reward for a job should be linked with the effort involved in that job
and the scheme should be just and fair to both employees and employers. This involves
the following:
(a) The standard required of the workers should be carefully set, if possible through
proper time and motion studies.
(b) If the work is of repetitive type, the entire benefit of the time saved should be
available to the worker but, in the case of non-standardised work or where precise
standards cannot be set, the benefit of the time saved, if any, should be shared by
the employer, the supervisor and the worker.
(ii) Well defined scheme: The scheme should be clearly defined and be capable of being
understood by the employees easily. The standards set should be such that they can be
achieved even by average employees. While standards are being set, the workers
concerned should be consulted.
(iii) Worker’s Expectations: As far as possible, no limit should be placed on the amount of
additional earnings; otherwise it will dampen the initiative of the workers. In this regard,
what is important is not what actually prevails but what the workers think—if they think,
even wrongly, that the employer will stop wages from rising beyond a certain limit, the
incentive scheme may not be really effective.
(iv) Stability: The scheme should be reasonable and stable, and should not be changed or
modified too often without consulting the employees.
(v) Charge on employees: The scheme should take care that the employees are not
penalised for reasons beyond their control.
(vi) Incentive based on quality: The scheme should provide for inspection of output so that
only good pieces qualify for incentives. It would even be better not to introduce any
incentive scheme if workmanship is of vital importance in sales.
(vii) Adequate Resources: The management should ensure that there is no cause for
complaint by the workers that they are sitting idle, say for want of tools or materials.
Management has to see that there is, as far as practicable, no interruption of production.
(viii) Limited Costs: The operation of the scheme should not entail heavy clerical costs. In fact the
scheme should facilitate the introduction of budgetary control and standard costing.
(ix) Morale booster : It should be capable of improving the morale of the employees and it
should be in conformity with the local trade union agreements and other government
regulations.
(x) Guaranteed wages : There should be a guaranteed wage on time basis which generally
works as a good psychological boost to incentive scheme.
(xi) Equality in payment: the effect of incentive scheme on those who cannot be covered should
be gauged and taken note of. Sometimes, highly skilled workers have perforce to be paid on
time basis whereas semiskilled or unskilled workers may be put on incentive scheme. If the
latter earn more than former, the incentive schemes on the whole prove harmful.
Essential characteristics of a good incentive system: to recapitulate
(i) It should be just both to the employer and to the employee. It should be positive and not
unnecessarily punitive and so operated as to promote confidence.
(ii) It should be strong both ways i.e. it should have a standard task and a generous return.
The latter should be in direct proportion to employee’s efforts. It should reflect the
employer’s contribution to the success of the company.
(iii) It should be unrestricted as to the amount of the earning.
(iv) It should be reasonable, apart from being simple, for employee to figure out his incentive
in relation to his individual performance, as far as practicable.
3.9.2 Identification of labour hours with work order or batches or capital job: For
identification of labour hours with work order or batches or capital jobs or overhead work
orders the following points are to be noted :
(i) The direct labour hours can be identified with the particular work order or batches or
capital job or overhead work orders on the basis of details recorded on source document
such as time sheet or job cards.
(ii) The indirect labour hours cannot be directly identified with the particular work order or
batches or capital jobs or overhead work orders. Therefore, they are traced to cost centre
and then assigned to work order or batches or capital jobs or overhead work orders by
using overhead absorption rate.

(iv) Stability in wages (iv) A firm cannot be sure of labour costs

already submitted.
3.10.1 (i) High wage plan: This plan was first introduced by Ford Motor Company (in USA)
in order to induce workers to exercise extra effort in their work.
Under this plan a worker is paid a wage rate which is substantially higher than the rate
prevailing in the area or in the industry. In return, he is expected to maintain a very high level
of performance, both quantitative and qualitative. As a result, high rate men are not as costly
or expensive as they might appear at first sight.
High wage plan is suitable where high quality of work and also increased productivity are required.
The advantage which may accrue from the implementation of this plan are :
(1) It is simple and inexpensive to operate.
(2) It helps in attracting highly skilled and efficient workers by providing suitable incentive.
(3) It reduces the extent of supervision.
(4) Increased productivity may result in reduction of unit labour cost.
3.10.1.(ii) Measured day work : According to this method the hourly rate of the time worker
consists of two parts viz, fixed and variable. The fixed element is based on the nature of the job i.e.
the rate for this part is fixed on the basis of job requirements. The variable portion varies for each
worker depending upon his merit rating and the cost of living index. The aggregate of fixed and
variable part for a day is termed as Measured day’s work rate of a worker.
As the rate is based on two different elements, there are separate time rates not only for each
worker but also for each job. This method does not find much favour with workers due to the
following :
1. The rates fixed are not easily understood by the workers.
2. Merit rating tends to be arbitrary and unless changed at rapid intervals, the ratings will
not reflect the correct ranking of the qualities of a worker.
3.10.1.(iii) Differential time rate : According to this method, different hourly rates are fixed
for different levels of efficiency. Up to a certain level of efficiency the normal time or day rate is
paid. Based on efficiency level the hourly rate increases gradually. The following table shows
different differential rates :
Up to, say 75% efficiency Normal (say ` N per hr.)
From 76% to 80% efficiency 1.10 × N
From 81% to 90% efficiency 1.20 × N
From 91% to 100% efficiency 1.30 × N
From 101% to 120% efficiency 1.40 × N
As this method is linked with the output and efficiency of workers, therefore, it cannot be
strictly called as a time rate method of wage payment. This method in fact is similar to
differential piece work system.
3.10.2 Payment by result: Under this system the payment made has a direct relationship
with the output given by a worker. The attendance of the worker or the time taken by him for
doing a job has no bearing on the payment. The system of payment by results may be
classified into the following four categories :
(a) Systems in which the payment of wages is directly proportionate to the output given by workers.
(b) Systems in which the proportion of the wage payment to the worker increases
progressively with increase in production.
(c) Systems in which payment rate decreases with the increase in output.
(d) Systems with earnings varying in proportions which differ at different levels of production.
3.10.2.(i) Straight piece work system
Under this system of wage payment, each operation, job or unit of production is termed a
piece. A rate of payment, known as the piece rate or piece work rate is fixed for each piece.
The wages of the worker depend upon his output and rate of each unit of output; it is in fact
independent of the time taken by him. The wages paid to a worker are calculated as :
Wages = Number of units produced × Piece rate per unit.
Considerable care and judgment are called for fixing the piece rate. If the rate fixed is too high
or too low, it would operate to the disadvantage of either the employer or the employee. Any
attempt on the part of the management to revise a piece rate, erroneously set too high, is
likely to lead to friction and conflict with labour. If on the other hand, it is too low, it would fail
in its objective. The only way all this may be avoided is by employing scientific methods of job
evaluation and time and motion study for the purpose of setting the rates.
Advantages Disadvantages

3.10.2 (ii) Differential piece work system : This system provide for higher rewards to
more efficient workers. The main feature of all differential piece-work systems is that several
piece rates on a slab scale are fixed for a job or operation which is put on piece-work. For
different levels of output below and above the standard, different piece rates are applicable.
Taylor Differential Piece Work System and Merrick Differential Piece Rate System are two
important differential piece work systems discussed briefly as below:
(a) Taylor’s differential piece work system - The Taylor’s Differential Piece Rate System
aims at rewarding efficient workers by providing increased piece rate beyond certain level of
output.
Under this system two widely differing piece-rates are prescribed for each job. The lower rate
is 83% of the normal piece rate and the higher rate is 125% of the normal piece rate. In other
words the higher rate is 150% of the lower rate. The lower rate is given to a worker when his
efficiency level is less than 100%. The higher rate is offered at efficiency level of either 100%
or more. Due to the existence of the two piece rates, the system is known as differential piece
rate system.
Note: Some authors also use 80% and 120% of the piece rates as lower and higher rates
respectively at the efficiency levels, as indicated in the above paragraph.
Advantages Disadvantages
1. It is simple to understand and operate. This system is quite harsh to workers, as a

Standard Time per Unit 1 Minute
Output per day is as follows:
Worker A – 390 Units
Worker B – 450 Units
Worker C – 600 Units
Working hours per day are 8.
Solution:
Earnings of Workers under Straight Piece Rate System:
Worker A = 390 units × ` 0.09 = ` 35.10
Worker B = 450 units × ` 0.09 = ` 40.50
Worker C = 600 units × ` 0.09 = ` 54.00
Solution
(i) When the worker performs the task in 10 hours, his earnings will be at the time wage rate
i.e. 10 hours × ` 20 per hour = ` 200.
(ii) When the worker performs the task is standard time i.e. in 8 hours, his earning will be:
8 hours × ` 20 = ` 160
Bonus @ 20% of time wages = ` 32
Total earnings ` 192
(iii) When the worker performs the task in less than the standard time his earning will be at
piece rate i.e.
50 units × ` 4 per unit = ` 200
The comparative rate of earnings per hour under the above three situations is:
(i) ` 200/10 hrs. = ` 20 per hour
(ii) ` 192/8 hrs. = ` 24 per hour
(iii) ` 200/6 hrs. = ` 33.33 per hour
3.10.4 Emerson’s efficiency system: Under this system minimum time wages are
guaranteed. But beyond a certain efficiency level, bonus in addition to minimum day wages is given.
A worker who is able to attain efficiency, measured by his output equal to 2/3rd of the
standard efficiency, or above, is deemed to be an efficient worker deserving encouragement.
The scheme thus provides for payment of bonus at a rising scale at various levels of
efficiency, ranging from 66.67% to 150%.
The levels are as mentioned below:
(i) For a performance below 66.67% only time rate wages without any bonus are paid.
(ii) Above 66⅔ % to 100% efficiency, bonus varies between 0.01% and 20%.
(iii) Above 100% efficiency bonus of 20% of basic wages plus 1% for each 1% increase in
efficiency is admissible.
This system is superior to one to the differential piece rate in so far as it encourages the slow
worker to do a little better than before. Also it does not pre-suppose a high degree of average
performance. Wages on time basis are guaranteed.

3.10.10 Rowan system: According to this system a standard time allowance is fixed for the
performance of a job and bonus is paid if time is saved.
Under Rowan System the bonus is that proportion of the time wages as time saved bears to

Illustration 16: (Calculation of earnings and effective hourly rate under Halsey scheme)
A skilled worker in XYZ Ltd. is paid a guaranteed wage rate of ` 30 per hour. The standard
time per unit for a particular product is 4 hours. P, a machineman, has been paid wages under
the Rowan Incentive Plan and he had earned an effective hourly rate of ` 37.50 on the
manufacture of that particular product.
Required: What could have been his total earnings and effective hourly rate, had he been put
on Halsey Incentive Scheme (50%)?
Solution:
Total earnings (under 50% Halsey Scheme) = Hours worked × Rate per hour + ½ × time

= 3 hours × ` 30 + ½ × 1 hour × `30 = ` 105
Total earnings ` 105
Effective hourly rate = = = ` 35

3.10.11 Barth system The formula used for calculating the remuneration under this system
is as follows :
Earnings = Hourly rate × Standard hours × Hours worked
The system is particularly suitable for trainees and beginners and also for unskilled workers. The
reason is that for low production efficiency, the earnings are higher than in the piece-work system
but as the efficiency increases, the rate of increase in the earnings falls.
This system is not suitable for workers having more than 100% efficiency as it does not provide
incentive on working at more than 100% efficiency.
Illustration 20: (Selection of appropriate incentive scheme)
Mr. A. is working by employing 10 skilled workers. He is considering the introduction of some
incentive scheme - either Halsey Scheme (with 50% bonus) or Rowan Scheme - of wage
payment for increasing the labour productivity to cope with the increased demand for the
product by 25%. He feels that if the proposed incentive scheme could bring about an average
20% increase over the present earnings of the workers, it could act as sufficient incentive for
them to produce more and he has accordingly given this assurance to the workers.
As a result of the assurance, the increase in productivity has been observed as revealed by
the following figures for the current month :
Hourly rate of wages (guaranteed) ` 2.00
Average time for producing 1 piece
by one worker at the previous performance 2 hours
(This may be taken as time allowed)
No. of working days in the month 25
No. of working hours per day for each worker 8
Actual production during the month 1,250 units
Required :
1. Calculate effective rate of earnings per hour under Halsey Scheme and Rowan Scheme.
2. Calculate the savings to Mr. A in terms of direct labour cost per piece under the schemes.
3. Advise Mr. A about the selection of the scheme to fulfill his assurance.
Solution
Working Notes:
1. Total time wages of 10 workers per month:
= No. of working days in the month × No. of working hours per day of each worker ×
Hourly rate of wages × No. of workers
= 25 days × 8 hrs. × ` 2 × 10 workers = ` 4,000
2. Time saved per month :
Time allowed per piece by a worker 2 hours
No. of units produced during the month by 10 workers 1,250 pieces
Total time allowed to produce 1,250 pieces (1,250 × 2 hours) 2,500 hours
Actual time taken to produce 1,250 pieces 2,000 hours
Time saved (2,500 hours – 2,000 hours) 500 hours
3. Bonus under Halsey scheme to be paid to 10 workers :
Bonus = (50% of time saved) × hourly rate of wages
= 50/100 × 500 hours × ` 2 = ` 500
Total wages to be paid to 10 workers are (` 4,000 + ` 500) ` 4,500, if Mr. A considers
3. From the labour cost per piece under Halsey scheme (` 3.60) and Rowan scheme
(` 3.84), it is quite clear that Halsey scheme brings about more saving than Rowan scheme
to the concern. But Halsey scheme does not fulfill the assurance given to the workers about
20% increase in their earnings as it secures only 12.5% [500/4,000 × 100] increase.
On the other hand, Rowan scheme secures 20% [800/4,000 × 100] increase in the earnings
and it fulfills the assurance. Therefore, Rowan scheme may be adopted.
Illustration 21: (Calculation of earnings under different schemes)
Wage negotiations are going on with the recognised Labour Union and the Management wants
you as the Cost Accountant of the Company to formulate an incentive scheme with a view to
increase productivity.
The case of three typical workers Achyuta, Ananta and Govida who produce respectively 180, 120
and 100 units of the company’s product in a normal day of 8 hours is taken up for study.
Assuming that day wages would be guaranteed at 75 paise per hour and the piece rate would be
based on a standard hourly output of 10 units, calculate the earnings of each of the three workers
and the labour cost per 100 pieces under (i) Day wages, (ii) Piece rate, (iii) Halsey scheme, and
(iv) The Rowan scheme.
Also calculate under the above schemes the average cost of labour for the company to produce
100 pieces.

methods discussed above.
Group Bonus - Group Bonus refers to the bonus paid for the collective efforts made by a
group of workers. The amount of bonus is distributed among the individual members of the
group on some agreed basis.
Group Bonus Schemes - Under a group bonus scheme, bonus is paid to a team/group of
employees working together.
Such a scheme is introduced generally where individual efficiency cannot be established for
the payment of bonus.
For example, in the construction work, it is the team work of masons and labourers which
produces results. If any incentive is to be offered, it should be offered to the team as a whole
and not to an individual. Group bonus is based on the combined output of the team as a
whole. The quantum of bonus is determined on the basis of the productivity of the team and
the bonus is shared by individual workers in specified proportions, often in the proportion of
wages on time basis.
Objectives of Group Bonus Schemes: The objectives of a group bonus scheme are the
following :-
(i) To create collective interest and team spirit among workers.
(ii) To create interest among supervisors to improve performance.
(iii) To reduce wastage in materials and idle time.
(iv) To achieve optimum output at minimum cost.
(v) To encourage individual members of the group, team where only the output of the team
as a whole can be measured.
Advantages of Group Bonus Schemes :
1. They create a sense of team spirit since all the workers in a group realise that their
personal incentives are dependent upon group effort.
2. A spirit of healthy competition amongst various groups doing identical jobs is also
created. This results is the elimination of excessive waste of materials.
3. The operators and supervisors also feel interested in raising the production to higher levels.
4. The scheme is usually easier to understand and entails less costing and accounting
work. It is easier to set up group activity targets, since the performance unit is large.
Schemes of group bonus - There are five schemes of group bonus as discussed below :
(1) Priestman’s Production Bonus: This method was adopted by Priestman Bros. Ltd., in 1917.
According to this method when the actual production in units or points exceeds the
standard fixed, a bonus is paid to the workers as additional wages equivalent to the
percentage of actual output over the standard output.
(2) Cost Efficiency Bonus: Under this scheme, the amount of bonus is calculated when the
cost is reduced below the normal established targets. Targets of cost, for example,
material cost, labour cost and overhead cost etc., per unit are fixed. If the measurement
of actual performance shows a saving in the total labour and material cost or a reduction
in the total cost per unit, a fair percentage of the saving is distributed among the staff.
Three popular schemes usually used for calculating the amount to be distributed to
workers as Bonus are as below :
(i) Nunn-Bush Plan: According to this plan a norm of direct labour cost is fixed and
expressed as a percentage of the sales value.
The amount calculated at this percentage is credited to a fund. The actual labour
cost is debited to this fund and the balance remaining to the credit of this fund is
distributed as bonus to all the workers and employees.
(ii) Scanlon Plan: Here also a fund is created for the normal cost of wages and
salaries. This fund is debited with the actual labour costs. Two-thirds to three-
fourths of the credit balance, if any, is distributed as bonus, the balance is kept as
reserve for future set-backs.
(iii) Rucker Plan: This plan is quite similar to Nunn-Bush Plan except that the
percentage for crediting the fund is based on the total value added by manufacturer
(i.e. the total cost less the value of the material) and not on total sales value.
(3) Town Gain Sharing Plan: Under this plan bonus is dependent upon a saving in the
labour cost as compared to standard. The bonus is calculated at 50% of the saving
achieved.
(4) Budgeted Expense Bonus: Bonus is determined in advance and paid as a percentage
of savings effected in the actual total expenses as compared to the budgeted expense. It
is payable to indirect workers also.
(5) Waste Reduction Bonus: Bonus becomes payable under this scheme if the team of
workers brings about a reduction in the percentage of material wastages as compared to
the standard set. It is applicable to industries where the material cost assumes a greater
proportion of the total cost.
Many times group bonus schemes do not enjoy the approval of workers. Some workers tend to
feel that their personal incentives are low merely because some members of the group are
lazy or inefficient. Such workers believe that it is better to provide incentives on individual
basis, if it is possible.
3.10.13 System of Incentive schemes for Indirect Workers: Since the setting of
work standards and measurement of output in the case of indirect workers is not an easy task
in respect of maintenance, internal transport, inspection, packing and cleaning, therefore the
introduction of a system of payment by results for indirect workers is difficult.
In spite of the aforesaid difficulty, it has been felt necessary to provide for incentives to

(a) General Incentive
(i) Standard output : 15,000 tonnes
Workers share in the net profits of the firm can be calculated by any of the following
ways:
(i) A fixed percentage may be allowed to the worker as bonus at the end of the financial year.
(ii) The profit earned, can be department wise and hence a fixed percentage of the department’s
profit can be allowed as profit sharing.
(iii) Profits may be computed per unit of output and a part of profit may be allowed to workers
on this basis.
Treatment in Costing: In foreign countries bonus is an ex-gratia payment and hence it is
regarded as an appropriation of profit not to be included in costs. In fact trade unions there do
not look upon bonus with favour.
In India however, payment of bonus is compulsory under the Payment of Bonus Act under
which 8.33% of wages earned or ` 100 whichever is higher, is the minimum bonus payable,
the maximum being 20%. Hence bonus must be treated as part of costs in India.
There can be two methods of dealing with bonus:
(i) It may be treated as part of overheads; in any case, this must be so for bonus paid to
indirect workers.
(ii) In the case of direct workers the bonus payable may be estimated beforehand and wage
rates for costing purposes suitably inflated by including the bonus that would be paid.
Example: A worker gets ` 800 p.m. as wages and it is expected that he will be paid two
months’ wages as bonus. His total earning will be ` 11,200 (` 9,600 + ` 1,600). If the worker
works for 2,400 hours in a year the wage rate for costing purposes will be : ` 4.67, i.e., `
11,200/2,400 hours.
Illustration 24: (Calculation and verification of wages paid to the worker)
During audit of account of G Company, your assistant found errors in the calculation of the
wages of factory workers and he wants you to verify his work.
He has extracted the following information :
(i) The contract provides that the minimum wage for a worker is his base rate. It is also paid
for downtimes i.e., the machine is under repair or the worker is without work. The
standard work week is 40 hours. For overtime production, workers are paid 150 percent
of base rates.
(ii) Straight Piece Work – The worker is paid at the rate of 20 paise per piece.
(iii) Percentage Bonus Plan – Standard quantities of production per hour are established by
the engineering department. The workers’ average hourly production, determined from
his total hours worked and his production, is divided by the standard quantity of
production to determine his efficiency ratio. The efficiency ratio is then applied to his
base rate to determine his hourly earnings for the period.
(iv) Emerson Efficiency Plan – A minimum wages is paid for production upto 66-2/3% of
standard output or efficiency. When the workers production exceeds 66-2/3% of the
standard output, he is paid bonus as per the following table :

Working notes :
1. Minimum wages = Total normal hours × rate per hour
= 40 hours × ` 1.80 = ` 72
Gross wages (computed) = No. of units × rate per unit
as per incentive plan = 400 units × ` 0.20 = ` 80
2. Minimum wages = Total normal hours × Rate per hour + Overtime
hours × Overtime rate per hour
= 40 hours × ` 1.80 + 6 hours × ` 2.70
= ` 72 + ` 16.20 = ` 88.20
Gross wages (computed)
as per incentive plan = 455 units × ` 0.20 = ` 91.00
3. Minimum wages = 40 hours × ` 1.80 + 4 hours × ` 2.70
= ` 72 + ` 10.80 = ` 82.80
Gross wages (computed) = 425 units × ` 0.20 = ` 85

achieve the increased output, the Board intends to offer a 1% increase on the piece work rate
of ` 1 per unit for every 2% increase in average individual output achieved.
To sell the increased output, it will be necessary to decrease the selling price by 4%.
Calculate the extra weekly contribution resulting from the proposed change and evaluate for
the Board’s information, the desirability of introducing the change.
Solution
1. Present average output per employee and total future expected output per week
Total present output
Present average output per employees per week =
Total number of present employees
48,000 units
= = 300 units
160 employees
Total Future expected output per week = Total number of future employees
(present output + 60% of present
output per employee)
= 120 employees (300 units + 60% ×
300 units)
= 57,600 units
2. Present and proposed piece work rate
Present piece work rate = ` 1.00 per unit
Proposed piece work rate = Present piece work rate + 30% × ` 1
= ` 1.00 + 0.30 P
= ` 1.30 per unit
3. Present and proposed sale price per unit
Present sales price per unit = ` 12.50
(` 6,00,000/48,000 units)
Proposed sale price per unit = ` 12
(` 12.50 – 4% × ` 12.50)
4. Present marginal cost (excluding wages) per unit :
Present sales value − Fixed expenses & profit − Contribution towards present wages
=
Present output (units)
But in the case of direct workers, two alternatives are possible. The additional charges may be
treated as overheads. Alternatively, the wage rates being charged to job may be computed by
including such payments; automatically then, such payments will be charged to the work done
alongwith wages of the worker. (It should be remembered that such wage rate will be only for
costing purposes and not for payment to workers). The total of wages and additional payment
should be divided by effective hours of work to get such wage rates for costing purposes.
Illustration 26: (Calculation of wage rate per hour)
A worker is paid `1000 per month and a dearness allowance of ` 200 p.m. Worker
contribution to provident fund is @ 10% and employer also contributes the same amount as
the employee. The Employees State Insurance Corporation premium is 6.5% of wages of
which 1.75% is paid by the employees. It is the firm’s practice to pay 2 months’ wages as
bonus each year.
The number of working days in a year are 300 of 8 hours each. Out of these the worker is
entitled to 15 days leave on full pay. Calculate the wage rate per hour for costing purposes.
Solution (`)
Wages paid to worker during the year (` 1,000 +200) x 12 14,400
Add: Employer Contribution to:
Provident Fund @ 10% 1,440
E.S.I. Premium 4.75% (6.5 – 1.75) 684
Bonus at 2 months’ wages (Basic + DA) 2,400
Total 18,924
Effective hours per year: 285 × 8 = 2,280
Wage-rate per hour (for costing purpose): ` 18,924/2,280 hours = `8.30
Illustration 27: (Calculation of earnings and labour cost)
Calculate the earnings of A and B from the following particulars for a month and allocate the
labour cost to each job X, Y and Z:
A B
(i) Basic wages ` 100 160
(ii) Dearness allowance (on basic wages) 50% 50%
(iii) Contribution to provident fund (on basic wages plus DA) 10% 10%
(iv) Contribution to employees’ state insurance (on basic wages plus DA)1.75% 1.75%
(v) Overtime Hours 10 -
The normal working hours for the month are 200. Overtime is paid at double the total of
normal wages and dearness allowance. Employer’s contribution to State Insurance is 4.75%
and Provident Fund are at equal rates of employees’ contributions. The two workers were
employed on jobs X, Y and Z in the following proportions:
Jobs
X Y Z
Worker A 40% 30% 30%
Worker B 50% 20% 30%
Overtime was done on job Y.

Normal wages are considered as basic wages
(Basic + D.A.)
Overtime = 2 × × 10 hours

= 2 × (` 150/200) × 10 hours = `15
Illustration 28: (Treatment of abnormal idle time)
In a factory working six days in a week and eight hours each day, a worker is paid at the rate
of ` 100 per day basic plus D.A. @ 120% of basic. He is allowed to take 30 minutes off during
his hours shift for meals-break and a 10 minutes recess for rest. During a week, his card
showed that his time was chargeable to :
Job X 15 hrs.
Job Y 12 hrs.
Job Z 13 hrs.
The time not booked was wasted while waiting for a job. In Cost Accounting, how would you
allocate the wages of the workers for the week?
Solution
Working notes:
(i) Total effective hours in a week :
[(8 hrs. – (30 mts. + 10 mts.)] × 6 days = 44 hours
(ii) Total wages for a week :
(` 100 + 120% of ` 100) × 6 days = ` 1,320
(iii) Wage rate per hour : = ` 30
(iv) Time wasted waiting for
job (Abnormal idle time): = 44 hrs. – (15 hrs. + 12 hrs. + 13 hrs.)
= 4 hrs.
Allocation of wages in Cost Accounting
(`)
Allocated to Job X : 15 hours × ` 30 = 450
Allocated to Job Y : 12 hours × ` 30 = 360
Allocated to Job Z : 13 hours × ` 30 = 390
Charged to Costing Profit & Loss A/c : 4 hours × ` 30 = 120
Total 1,320
3.11.3 Holiday and leave wages: One alternative to account for wages paid on account of
paid holiday and leave can be to include them as departmental overheads. In such a case, it is
necessary to record such wages separately from “worked for wages”. Such a segregation can
be made possible by providing a separate column in the payroll for holiday and leave wages in
the same way as there are columns for dearness allowance, provident fund deductions, etc. If,
however, a separate or additional column cannot be provided for this purpose it would be
necessary to analyse the payroll periodically to ascertain how much of the total payment
pertains to “worked for wages” and how much is attributed to leave and holiday wages.
Another way could be to inflate the wage rate for costing purposes to include holiday and
leave wages. This can be done only in the case of direct workers.
Illustration 29: (Calculation of leave wages)
Calculate the labour hour rate of a worker X from the following data :
Basic pay ` 1,000 p.m.
D.A. ` 300 p.m.
Fringe benefits ` 100 p.m.
Number of working days in a year 300. 20 days are availed off as holidays on full pay in a
year. Assume a day of 8 hours.
Solution
(a) (i) Effective working days in a year 300
Less : Leave days on full pay 20
Effective working days 280 days
Total effective working hours (280 days × 8 hours) 2,240
(ii) Total wages paid in a year (`)
Basic pay 12,000
D.A. 3,600
Fringe benefits 1,200
16,800
(iii) Hourly rate : ` 16,800/2,240 hours ` 7.50
3.11.4 Night shift allowance: In some cases, workers get extra payment if they work at
night. Since the extra payment is not for any particular job, therefore such a payment should
be treated as part of overheads.
3.11.5 Principles of remuneration: The term ‘remuneration’ has been defined as the
reward for labour and service. It is the result of the agreement between the employer and the
employee, whereby for a specified work or service rendered by the employee the employer
agrees to pay a specified sum of money. Apart from this an employee by virtue of the fact that
he is an employee becomes entitled to certain non-monetary benefits.
The method of remuneration adopted varies from industry to industry and, in certain cases,
even among different units in the same industry. Whatever be the variation, the method of
fixing remuneration payable to the various categories of employees has to be based on certain
3.11.6 Absorption rates of labour cost : Labour cost as stated above include monetary
compensation and non-monetary benefits to workers.
Monetary benefits include, basic wages, D.A., overtime pay, incentive or production bonus
contribution to employee provident fund, House Rent Allowance, Holiday and vacation pay etc.
The non-monetary benefits include medical facilities, subsidized canteen services, subsidized
housing, education and training facilities.
Accounting of monetary and non-monetary benefits to indirect workers does not pose any
problems because the total of monetary and non-monetary benefits are treated as overhead
and absorbed on the basis of rate per direct labour hour, if overheads are predominantly
labour oriented.
For direct workers, the ideal method is to charge jobs or units produced by supplying per hour
rate calculated as below :
Total of estimated monetary benefits and cost of non - monetary benefits
Rate per hour =
Budgeted direct labour hours - Normal idle time
Another alternative method is to treat the monetary benefits other than basic wages and
dearness allowance as well as cost of non-monetary benefits as overheads.
3.13 Summary
• Labour Cost: Cost incurred for hiring of human resource of employees
• Direct Labour: Any Labour Cost that is specifically incurred for or can be readily
charged to or identified with a specific job, contract, work order or any other unit of cost.
• Idle Time: The time for which the employer pays but obtains no direct benefit or for no
productive purpose.
• Normal Idle Time: Time which can not be avoided or reduced in the normal course of
business. The cost of normal idle time should be charged to the cost of production.
• Abnormal Idle Time: It arises on account of abnormal causes and should be charged to
Costing Profit and Loss account.
• Time Keeping: It refers to correct recording of the employees attendance time
• Time Booking: It is basically recording the details of work done and the time spent by
workers on each job or process.
• Overtime: Payment to workers, when a worker works beyond the normal working hours.
Usually overtime has to be paid at double the rate of normal hours.
• Overtime Premium: It’s the amount of extra payment paid to a worker under overtime.
• Labour Turnover: It is the rate of change in labour force during a specified period due to
resignation, retirement and retrenchment. If the labour turnover is high, it’s a sign of
instability and may affect the profitability of the firm.
• Labour turnover can be measured through the following methods:
Number of employees replaced
(i) Replacement Method: × 100
Average number of employees on roll
OR
No. of separations + No. of accessions
× 100
Average number of workers
