COST

Cost refers to the amount of expenditure (actual or notional) incurred on, or attributable to, a given product, service, or activity. It represents the monetary measurement of resources such as material, labour, and expenses used for producing goods or rendering services.

In cost accounting, cost is not limited to past expenditure only; it may also include future or estimated costs incurred for decision-making purposes. Cost helps management determine product pricing, control expenses, and evaluate efficiency.

Definitions of Cost

• ICMA (Institute of Cost and Management Accountants, UK)

“The amount of expenditure (actual or notional) incurred on a given thing.”

• Walter B. Meigs

“Cost is the value of economic resources used as a result of producing or doing the thing being measured.”

• Horngren & Foster

“A cost is a sacrificed resource to achieve a specific objective.”

Elements of Cost

Cost is generally classified into the following three main elements:

1. Material Cost

Material cost refers to the cost of raw materials, components, and supplies used directly or indirectly in production.

• • Direct Material: Materials that can be easily identified with a specific product (e.g., raw cotton in textile production).

  • Indirect Material: Materials that cannot be directly traced to a product (e.g., lubricants, cleaning supplies).

2. Labour Cost

Labour cost is the remuneration paid to workers for their physical or mental efforts.

• • Direct Labour: Wages paid to workers directly involved in production (e.g., machine operators).

  • Indirect Labour: Wages paid to workers not directly involved in production (e.g., supervisors, security staff).

3. Expenses (Overheads)

Expenses include all other costs incurred apart from material and labour.

• • Direct Expenses: Expenses directly attributable to a product (e.g., royalty, special design charges).

  • Indirect Expenses: Expenses that cannot be directly linked to a product (e.g., rent, electricity, depreciation).

Types of Cost

Costs are classified into different types in cost accounting to help management in cost control, planning, decision-making, and performance evaluation. The major types of cost are explained below:

1. Fixed Cost

Fixed cost is the cost that remains constant in total irrespective of changes in the level of output within a relevant range. These costs are incurred even when production is zero.

Examples include factory rent, insurance, managerial salaries, and depreciation. Although total fixed cost remains unchanged, fixed cost per unit decreases with an increase in production. Fixed costs are also called period costs.

2. Variable Cost

Variable cost changes directly and proportionately with the level of production or activity. An increase in output results in a corresponding increase in total variable cost.

Examples include direct material, direct labour, and direct expenses such as power used in production. Variable costs are important for marginal costing and break-even analysis.

3. Semi-Variable Cost

Semi-variable cost contains both fixed and variable elements. One portion of the cost remains constant, while the other portion varies with output.

Examples include electricity charges, telephone expenses, and maintenance costs. These costs remain fixed up to a certain level and increase beyond that level.

4. Direct Cost

Direct cost is the cost that can be directly identified and allocated to a specific product, job, or process without any difficulty.

Examples include direct material, direct labour, and direct expenses such as royalty. Direct costs form part of prime cost and are easy to trace.

5. Indirect Cost

Indirect cost is the cost that cannot be directly traced to a particular product or service and is incurred for overall operations.

Examples include factory rent, indirect wages, supervisor salaries, and depreciation. These costs are also known as overheads.

6. Historical Cost

Historical cost refers to the actual cost incurred in the past for acquiring an asset or producing goods.

These costs are recorded in accounting books and are useful for financial reporting, but they may not be suitable for future decision-making.

7. Standard Cost

Standard cost is a predetermined cost established under normal working conditions and efficiency levels.

It serves as a benchmark for measuring actual performance and helps in cost control through variance analysis.

8. Marginal Cost

Marginal cost is the additional cost incurred for producing one extra unit of output.

It includes only variable costs and excludes fixed costs. Marginal cost is useful for pricing decisions and profit planning.

9. Opportunity Cost

Opportunity cost is the benefit or profit foregone by choosing one alternative over another.

It does not involve actual cash outflow but is important for managerial decision-making.

10. Sunk Cost

Sunk cost is the cost that has already been incurred and cannot be recovered.

Examples include past research expenses and cost of obsolete machinery. Sunk costs are irrelevant for future decisions.

COSTING

Costing is the technique and process of determining the cost of a product, service, or activity. It involves collecting, classifying, analyzing, and allocating costs systematically to ascertain the total cost and cost per unit. Businesses use costing to control expenses, improve efficiency, and set competitive prices.

Costing helps in:

• Determining selling prices

• Controlling and reducing costs

• Measuring profitability

• Budgeting and forecasting

Definitions of Costing

• ICMA (UK)

“Costing is the technique and process of ascertaining costs.”

• Wheldon

“Costing is the classifying, recording, and appropriate allocation of expenditure for the determination of the costs of products or services.”

• CIMA (Chartered Institute of Management Accountants)

“Costing is the process of identifying, measuring, analyzing, and reporting cost information to management for decision-making.”

Methods of Costing

Methods of Costing refer to the various procedures used to ascertain the cost of a product, service, or operation. The method selected depends on the nature of business, type of production, and industry requirements. Each method helps in accurate cost determination and effective cost control.

1. Job Costing

Job costing is a method where costs are collected and ascertained for each individual job or order separately.

It is suitable for industries where work is done as per customer specifications. Each job is treated as a separate cost unit. Examples include printing presses, repair workshops, shipbuilding, and tailoring units. Job costing helps in determining profitability of each job.

2. Contract Costing

Contract costing is a special form of job costing used for large-scale contracts executed over a long period.

It is mainly used in construction activities such as building roads, bridges, dams, and buildings. Each contract is treated as a separate cost unit. Costs like material, labour, plant, and overheads are recorded contract-wise. Profit is recognized gradually as the contract progresses.

3. Batch Costing

Batch costing is used when identical products are manufactured in batches.

The total cost of a batch is calculated first and then divided by the number of units in the batch to find the cost per unit. This method is commonly used in pharmaceutical companies, bakeries, footwear industries, and toy manufacturing units.

4. Process Costing

Process costing is applied in industries where production is continuous and products are homogeneous.

Costs are accumulated for each process or department and then averaged over the units produced. Examples include cement, sugar, paper, chemicals, and textile industries. This method is useful where individual product identification is not possible.

5. Unit Costing (Single Output Costing)

Unit costing is used when a single product or a uniform product is produced continuously.

The total cost of production is divided by the number of units produced to determine the cost per unit. This method is suitable for industries such as brick manufacturing, mining, cement, and steel production.

6. Operating Costing (Service Costing)

Operating costing is used to ascertain the cost of services rendered rather than goods produced.

It is applied in service-oriented organizations such as transport services, hospitals, hotels, cinemas, and power generation companies. Cost per unit of service, such as cost per kilometer or cost per bed, is calculated.

7. Multiple Costing (Composite Costing)

Multiple costing involves the use of more than one costing method for determining the total cost of a product.

It is suitable for complex products consisting of several components. Examples include automobile, aircraft, and heavy machinery industries, where job costing, process costing, and unit costing may be used together.

8. Operation Costing

Operation costing is a refined form of process costing where costs are ascertained for each operation instead of each process.

It is suitable for industries where operations are clearly defined, such as engineering and assembly industries. This method provides better control over operational efficiency.

9. Departmental Costing

Departmental costing involves ascertaining costs department-wise to determine the cost of output of each department.

It is useful in large organizations where production is divided into several departments. This method helps in comparing efficiency and profitability of different departments.

10. Uniform Costing

Uniform costing is not a separate method but a system where different firms in the same industry use the same costing principles and methods.

It facilitates cost comparison, price fixation, and healthy competition among firms within the industry.
