Unit - I Introduction To Cost Accounting
To understand the meaning of Cost Accounting following terms are required to be understood:
1. Cost
2. Cost Accountancy
3. Costing
4. Cost Accounting
5. Cost control and
6. Cost audit.
1. Cost:-It has been defined by Institute of Cost and Management Accountants in England (ICMA) as "the amount of
expenditure incurred or attributed on a given thing". Eg. Cost of a calculator means the material, labour and wages
directly required to produce a calculator and some portion of indirect expenses like office expenses, rent etc, allocated or
apportioned to it.
2. Cost Accountancy:-ICWA has defined Cost Accountancy as "Cost Accountancy is the application of costing and cost
accounting principles, methods and techniques to the science, art and practice of cost control and the ascertainment of
profitability. It includes the presentation of information derived therefrom for the purpose of management decision
making
Cost Accountancy is science since the cost accountant should possess the systematic knowledge to discharge his
responsibility and functions. It is an art since the cost accountant should have the ability and skill to apply his knowledge
to the various aspects such as ascertainment of costs, control of costs, ascertainment of profitability, marginal costing etc.
Cost Accountancy includes various subjects such as Costing, Cost Accounting, Cost Control and Cost Audit.
3. Costing:-According to ICMA, "Costing is the technique And process of ASCertAining cost". Wheldon defines Costing
as under: "Costing is the classifying, recording, and appropriate allocation of expenditure for the determination of cost of
products or services; and for the presentation of suitably arranged data for the purposes of control and guidance of the
management. It includes the ascertainment of the cost of every order, job, contract, process, service or unit as may be
appropriate. It deals with the cost of production, selling and distribution. Thus, it helps in knowing the cost of various
services and products and also gives information as to what could have been the cost by pointing out where and how they
have gone wrong with facilities to correct the same."
3. Cost Accounting:-According to ICMA, "Cost Accounting is the process of accounting from the point at which
expenditure is incurred or committed to the establishment of its ultimate relationship with cost centers and cost units. In
its widest usage, it embraces the preparation of statistical data, application of cost control methods and the ascertainment
of profitability of the activities carried out or planned".
In simple language, Cost Accounting is accumulation, classification, analysis and interpretation of cost data for
ascertainment of cost, operational planning and control and for decision making.
4. Cost Control:-It is defined as 'the guidance and regulation by executive action of costs of operating on undertaking. It
is exercised through a number of techniques such as Standard Costing and Budgetary Control. Standard Costing is a
system to control the cost of each unit through pre-determined cost, its comparison with actual cost and analysis of
variances together with their causes. Budgetary control means laying down in monetary and quantitative terms what
exactly has to be done, how to do it over a coming period and then to ensure that actual results do not diverge from
planned course more than necessary.
5. Cost Audit:-It is defined by ICMA as, "the verification of cost accounts and a check on the adherence to the cost
accounting plan. It is an independent expert examination of the cost accounts of different outputs of an undertaking and a
verification whether such accounts of the different output, serve the purpose intended".
Cost Accounting may be regarded as a specialized branch of accounting which involves classification, accumulation,
assignment and control of costs." The costing terminology of C.I.M.A. London defines cost accounting as "the process of
accounting for costs from the point at which expenditure is incurred or committed to the establishment of its ultimate
relationship with cost centers and cost units. In its widest usage, it embraces the preparation of statistical data, the
application of cost control methods and the ascertainment of profitability of activities carried out or planned".
Wheldon defines cost accounting as "classifying, recording and appropriate allocation of expenditure for determination of
costs of products or services and for the presentation of suitably arranged data purposes of control and guidance of
management". It is thus a formal mechanism by means of which costs of products or services are ascertained and
controlled.
Cost Recording and Classification:-Cost accounting systematically records and categorizes all costs, including direct
and indirect costs, fixed and variable costs, and product and period costs.
Cost Analysis and Interpretation:-It involves examining and evaluating the different cost elements to understand their
behavior and impact on the overall cost of a product or service.
Cost Control and Reduction:-Cost accounting helps in identifying areas of cost reduction and implementing strategies to
control expenses.
Decision Making:-Cost accounting provides the data needed for managerial decisions related to pricing, budgeting,
resource allocation, and cost control.
Budgeting and Forecasting:-Cost accounting assists in preparing budgets and forecasts for the future, which are essential
for financial planning and resource allocation.
Performance Evaluation:-Cost accounting helps evaluate the efficiency and performance of different departments,
products, or processes by comparing actual costs with budgeted costs.
Pricing Decisions:-Cost data is crucial for determining pricing strategies and fixing the selling prices of goods and
services.
Internal Focus:-Cost accounting focuses on internal management needs, unlike financial accounting, which primarily
focuses on external reporting to stakeholders.
Emphasis on Operational Aspects:-Cost accounting is closely linked to the operational aspects of a business, including
production, manufacturing, and service delivery.
Flexibility and Tailorability:-Cost accounting can be tailored to the specific needs of a company and its industry
2. Cost Control:- Monitoring and controlling costs to prevent wastage and improve efficiency. Identifying areas where
costs can be reduced or optimized. Setting standards for materials, labor, and overheads and comparing actual
performance against these standards.
3. Decision Making:- Providing information for pricing decisions, determining the minimum price to charge for a product
or service. Supporting budgeting and forecasting by providing cost data for realistic planning. Helping with make-or-buy
decisions, determining whether to manufacture a component or purchase it externally. Analyzing profitability to
determine which products or services are contributing most to the bottom line.
4. Profitability Analysis:-Determining the profitability of each product or service. Analyzing cost-volume-profit (CVP)
relationships to understand how changes in sales volume affect profitability.
5. Budgeting and Budgetary Control:- Preparing budgets and implementing budgetary control to ensure that actual
costs are within the planned limits. Monitoring and analyzing variances between budgeted and actual costs.
1. Cost Ascertainment: Determining the total cost of producing a product or service, including direct and indirect costs.
2. Cost Control: Monitoring and managing costs to ensure they are within budget and identify areas for improvement.
3. Cost Analysis: Examining different cost behaviors (fixed, variable, etc.) to understand their impact on profitability and
performance.
4. Pricing Decisions: Using cost data to determine competitive pricing strategies that ensure profitability.
5. Budgeting and Forecasting: Cost accounting provides the basis for creating budgets and forecasting future costs.
6. Variance Analysis: Comparing actual costs to standard or budgeted costs to identify and analyze deviations
(variances).
7. Performance Evaluation: Assessing the efficiency and effectiveness of operations and management by analyzing cost
data.
8. Decision-Making: Providing cost information to support various management decisions, such as product mix,
production volume, and capital investment.
9. Cost Classification: Categorizing costs into different types (e.g., direct materials, direct labor, manufacturing
overhead) to facilitate analysis.
10. Cost Allocation and Apportionment: Distributing costs among different departments, products, or services.
11. Inventory Management: Tracking and managing inventory costs to optimize purchasing and storage.
12. Job Costing and Process Costing: Utilizing different costing methods to suit different industries and production
processes.
13. Activity-Based Costing (ABC): Analyzing costs based on activities rather than traditional cost categories.
In essence, the scope of cost accounting is comprehensive and essential for effective business management. It provides
valuable information for cost control, performance evaluation, and strategic decision-making
Pricing:- Cost accounting helps businesses understand the costs associated with producing a product or service, allowing
them to set prices that are competitive yet profitable.
Product Mix:-By analyzing the profitability of different products, businesses can make informed decisions about which
products to prioritize and whether to expand, maintain, or discontinue certain product lines.
Resource Allocation:-Cost information helps managers allocate resources effectively, ensuring that they are used in the
most efficient and profitable way.
2. Cost Control:
Identifying Variances:-Cost accounting helps identify areas where actual costs deviate from planned or standard costs,
allowing businesses to pinpoint inefficiencies and implement corrective actions.
Cost Reduction:-By understanding the cost structure of a business, managers can identify areas where costs can be
reduced without compromising quality or efficiency.
Budgeting:- Cost accounting provides the data needed to create accurate budgets, which are essential for financial
planning and control.
3. Performance Evaluation:
Departmental Performance:-Cost accounting helps evaluate the performance of different departments or business units
by providing information on their costs and profitability.
Employee Performance:-By tracking individual worker performance against cost standards, cost accounting can be used
to identify and reward efficient workers.
4. Operational Efficiency:
Process Improvement:-Cost accounting reveals areas where processes can be improved, leading to greater efficiency and
cost savings.
Resource Optimization:-By understanding how costs are incurred, businesses can optimize their use of resources, such as
materials, labor, and machinery.
5. Compliance:
Tax Reporting:-Cost accounting provides the information needed to comply with tax regulations and other legal
requirements.
Financial Reporting:-While cost accounting is primarily an internal tool, it can also provide valuable information for
external financial reporting, such as in calculating the cost of goods sold.
CLASSIFICATION OF COST
Fixed Costs: These costs remain constant regardless of the level of production or sales, such as rent, salaries, and
insurance.
Variable Costs: These costs change proportionally with the level of production or sales, such as raw materials, direct
labor, and sales commissions.
Semi-Variable Costs: These costs have both a fixed and a variable component, such as utilities or maintenance contracts.
Direct Costs: These costs can be directly traced to a specific product, service, or department, such as direct materials and
direct labor.
Indirect Costs: These costs cannot be directly traced to a specific product, service, or department but are incurred to
support the overall operation of a business, such as rent, utilities, and administrative salaries.
Cost of Revenue (Cost of Goods Sold): This includes the direct costs of producing a product or service, such as raw
materials and direct labor.
Research and Development Costs: These costs are incurred to develop new products or processes.
Selling and Marketing Costs: These costs are incurred to promote and sell products or services.
General and Administrative Costs: These costs are incurred to support the overall operation of a business, such as rent,
utilities, and administrative salaries.
Relevant Costs: These costs are considered when making decisions about future actions, such as avoidable costs,
incremental costs, and opportunity costs.
Irrelevant Costs: These costs are not considered when making decisions about future actions, such as sunk costs.
Normal vs. Abnormal Costs: Normal costs are those typically incurred during the production process, while abnormal
costs are unusual and infrequent expenses.
Controllable vs. Non-Controllable Costs: Controllable costs are those that can be influenced by management decisions,
while non-controllable costs are those that are outside the control of management
ELEMENTS OF COST
1. Material Costs:
Direct Materials: Raw materials that are directly used in the production of a good or service and are easily identifiable in
the finished product (e.g., wood for furniture, cloth for shirts).
Indirect Materials: Materials that are not directly part of the finished product but are essential to the production process
(e.g., cleaning supplies, ink for printing).
2. Labor Costs:
Direct Labor: The wages and benefits of employees who are directly involved in producing the good or service (e.g.,
assembly line workers).
Indirect Labor: The wages and benefits of employees who support the production process but are not directly involved
in creating the product (e.g., supervisors, maintenance staff).
3. Expenses:
Direct Expenses: Costs that can be directly traced to a specific product or job (e.g., shipping costs for a particular order).
Indirect Expenses: Costs that are not directly traceable to a specific product or job but are necessary for the overall
operation of the business (e.g., rent, utilities, marketing expenses).
TENDER:
Purpose: To invite bids for a larger contract or project.
Scope: Typically for complex projects or large-scale purchases.
Formality: Formal and involves a detailed process.
Binding: Can lead to a legally binding contract after selection.
Example: A government department inviting bids for the construction of a new bridge
RECONCILIATION STATEMENT
Reconciliation involves comparing two sets of records to identify differences and make necessary adjustments.
Common examples include bank reconciliation (matching a company's records with its bank statements) and
reconciliation of cost and financial statements.
It helps to ensure that financial data is consistent and reliable, which is essential for accurate reporting and decision-
making.
Accuracy and Integrity: Reconciliation helps ensure that financial records are accurate and reflect a true
picture of a company's financial health.
Fraud Detection: By comparing different records, reconciliation can uncover errors, omissions, or
unauthorized transactions that could indicate fraud.
Cash Flow Management: Reconciliation can help identify discrepancies in cash inflows and outflows, leading
to a better understanding of cash flow patterns.
Improved Decision-Making: Accurate and reliable financial data, facilitated by reconciliation, allows for more
informed decision-making by management and stakeholders.
Compliance: Reconciliation can also help ensure compliance with accounting standards and regulations.
Internal Control: Reconciliation serves as a crucial internal control mechanism, helping to prevent errors and
ensure that financial information is reliable
UNIT – II
PROCESS COSTING & OPERATING COSTING
PROCESS COSTING INTRODUCTION:
Process costing is a cost accounting method used for industries that mass-produce identical or similar products
through a continuous process. It calculates the average cost per unit by dividing the total production costs by the
number of units produced. This method is suitable for industries like chemicals, textiles, and food processing
where products are standardized.
Definition: Process costing is a cost accounting method used in manufacturing industries where large quantities
of homogeneous products are produced through a continuous or repetitive process. It focuses on allocating costs
to each stage or department of production and then calculating the average cost per unit.
FEATURES:
Continuous Mass Production: Process costing is most effective when products are produced in large quantities
through a continuous or repetitive process.
Homogeneous Products: The products must be relatively similar or identical to make calculating average costs
per unit meaningful.
Cost Accumulation by Process: Costs are accumulated for each stage or process of production, rather than for
individual jobs or batches.
Average Cost per Unit: The total cost of each process is divided by the number of units produced in that
process to determine the average cost per unit.
Focus on Efficiency: Process costing helps businesses track and control production costs, identify potential
inefficiencies, and make informed pricing decisions.
APPLICABILITY:-
Industries with Continuous Production: Process costing is widely used in industries like oil refining,
chemical processing, food processing, and textile manufacturing.
Standardized Products: It's also applicable to industries that produce large quantities of similar or identical
products, such as paper, plastics, and beverages.
Companies with Multiple Production Stages: Businesses with a multi-stage production process can utilize
process costing to track costs at each stage and identify potential areas for improvement.
1. Simplicity: Easy to apply when production is continuous and units are identical.
2. Cost Control: Helps management track costs at each stage of production, making it easier to control waste,
losses, and inefficiencies.
3. Average Costing: Costs are spread evenly across all units, which is useful when products are homogeneous.
4. Efficiency Measurement: Allows businesses to measure performance and productivity for each process or
department.s
5. Automation-Friendly: Fits well with automated, mass-production systems where manual cost tracing is
difficult.
1. Service-Oriented: Used for services like transport, power supply, healthcare, hospitality, etc.
2. Cost Unit: The cost is determined per unit of service — e.g., per passenger-km, per ton-km, per room-night,
etc.
3. Recurring Costs: Expenses like fuel, wages, depreciation, and maintenance occur regularly.
4. Fixed and Variable Costs: Operating costs are classified into fixed (standing charges) and variable (running
costs).
5. Comparability: Cost per unit helps compare performance over different periods or services.
Ascertain Cost per Unit of Service: To calculate the accurate cost for each unit of service provided.
Cost Control: Helps identify and control unnecessary or excessive costs.
Pricing Decisions: Supports management in setting fair prices for services
Performance Evaluation: Helps evaluate efficiency and productivity of service operations.
IMPORTANCE OF OPERATING COSTING
1. Helps in Service Pricing: Ensures the service is neither underpriced nor overpriced.
2. Cost Reduction: Identifies areas of inefficiency and suggests scope for cost-saving.
3. Budgeting and Planning: Assists in preparing future cost estimates and operational budgets.
4. Management Decision-Making: Provides reliable cost data to aid in strategic planning.
1. Standing Charges (Fixed Costs): Costs that do not vary with the level of service (e.g., insurance, salaries,
and depreciation).
2. Running Costs (Variable Costs): Costs that vary directly with usage (e.g., fuel, lubricants, spare parts).
3. Maintenance Costs: Costs of repairing and maintaining service assets (e.g., vehicle servicing, equipment
repair).
UNIT III
MARGINAL COSTING AND DECISION MAKING
Marginal costing is a cost accounting technique that focuses on variable costs to understand their impact on
profitability and aid in decision-making. It helps in cost control by identifying areas where variable costs can be
reduced, ultimately improving profitability. By analyzing the contribution margin and break-even point,
businesses can make informed decisions about pricing, production levels, and product mix.
WHAT IS BUDGET?
Budgeting is essentially planning how to spend money wisely. It helps companies decide if they have enough
funds for their plans and needs. If your expenses surpass your income, budgeting helps prioritize what's most
important. This can mean listing all expenses or focusing on key categories. Some companies use spreadsheets,
others use budgeting apps, to create their budgets.
TYPES OF BUDGETING
2. Activity-based Budgeting
Activity-based budgeting is a top-down type of budget that determines the amount of inputs required to support
the targets or outputs set by the company. For example, a company sets an output target of $100 million in
revenues. The company will need to first determine the activities that need to be undertaken to meet the sales
target, and then find out the costs of carrying out these activities.
Value proposition budgeting is really a mindset about making sure that everything that is included in the budget
delivers value for the business. Value proposition budgeting aims to avoid unnecessary expenditures – although
it is not as precisely aimed at that goal as our final budgeting option, zero-based budgeting.
4. Zero-based Budgeting
As one of the most commonly used budgeting methods, zero-based budgeting starts with the assumption that all
department budgets are zero and must be rebuilt from scratch. Managers must be able to justify every single
expense. No expenditures are automatically “Okayed”. Zero-based budgeting is very tight, aiming to avoid any
and all expenditures that are not considered absolutely essential to the company’s successful (profitable)
operation. This kind of bottom-up budgeting can be a highly effective way to “shake things up”.
The zero-based approach is good to use when there is an urgent need for cost containment, for example, in a
situation where a company is going through a financial restructuring or a major economic or market downturn
that requires it to reduce the budget dramatically.
Zero-based budgeting is best suited for addressing discretionary costs rather than essential operating costs.
However, it can be an extremely time-consuming approach; so many companies only use this approach
occasionally.
DIFFERENCE BETWEEN FLEXIBLE BUDGET AND CASH BUDGET
A flexible budget adjusts to varying activity levels, providing budgeted costs for different output levels, while a
cash budget focuses on managing cash inflows and outflows over a period, helping ensure sufficient
liquidity. Essentially, a flexible budget is about managing costs and revenue based on changing activity, while a
cash budget is about managing the actual flow of money.
Here's a more detailed comparison:
FLEXIBLE BUDGET:
Focus: Adjusts to changes in activity (e.g., sales volume, production volume).
Purpose: Provides a more accurate performance evaluation by comparing actual results to budgeted figures
adjusted for the actual level of activity.
Examples: A restaurant with a fluctuating number of customers may use a flexible budget to adjust for higher
food costs during busy periods.
Advantages: Allows for more accurate performance evaluation and better control over variable costs.
Limitations: Can be more complex to create and maintain than a static budget.
Cash Budget:
CASH BUDGET:
Focus: Predicting cash inflows and outflows over a specific period.
Purpose: Helps manage liquidity, ensuring the organization has enough cash to meet its obligations.
Examples: A company planning for a large equipment purchase might use a cash budget to ensure they have
enough funds.
Advantages: Provides a clear picture of cash availability and helps identify potential cash shortages.
Limitations: Focuses solely on cash and may not capture the full picture of financial performance.
Flexible budgets are for planning and evaluating performance based on changes in activity levels, while cash
budgets are for managing the actual flow of cash. Flexible budgets are part of a broader budgeting process, while
cash budgets are often a separate budget, though they are influenced by other budgets like the sales budge t
