Cost Accounting Standards are a comprehensive framework issued by the Institute of Cost Accountants of India to provide consistency, accuracy, and reliability in cost determination, classification, allocation, and presentation. These standards help organisations maintain a uniform approach in preparing cost statements, which are essential for managerial decision-making, statutory reporting, and inter-firm comparability. Covering a total of twenty-four distinct standards, each focuses on a specific element of cost such as materials, labour, utilities, overheads, or depreciation, and prescribes methods to ensure correct valuation and disclosure.
CAS-1 – Classification of Cost
The first standard in the series establishes a structured approach to grouping and categorising costs for disclosure and presentation in cost statements related to products or services. Proper classification is crucial because it ensures that costs are recorded in a way that supports accurate analysis, control, and decision-making.
The scope of this standard applies to cost statements where cost classification, presentation, and disclosure are required, including situations where these statements need to be attested. It is relevant for both manufacturing and service sectors and can be applied to internal reporting as well as statutory submissions.
The standard outlines several bases for classification. Costs can be classified by nature of expenses, which refers to the type of resource consumed, such as materials, labour, or services. Another basis is traceability to a cost object, which separates costs into direct and indirect components. By function, costs are grouped according to the activity they support, such as production, administration, or marketing. Classification can also be made according to cost behaviour, distinguishing between fixed, variable, and semi-variable costs. Finally, costs can be grouped by the nature of the production or operational process, which is particularly relevant in industries with multiple stages of processing. This multi-dimensional approach ensures that the same set of cost data can be analysed from different perspectives.
CAS-2 – Capacity Determination
This standard focuses on setting uniform principles and methods for determining capacity with a reasonable level of accuracy. Capacity determination is essential in cost accounting because it affects how overheads are assigned, how performance is measured, and how efficiency is evaluated.
The scope covers cost statements where capacity determination is necessary for allocating overheads. It applies to various industries where production or operational capacity impacts cost structures and pricing decisions.
Capacity is measured in terms of units of production, services rendered, or equivalent machine or man-hours. The standard recognises several categories of capacity. Installed capacity refers to the maximum output achievable under ideal conditions, taking into account the design and technical specifications of equipment and facilities. Normal capacity represents the average production achievable over a period under normal working conditions, considering routine maintenance, holidays, and typical interruptions. By standardising the measurement of capacity, this standard ensures that comparisons of efficiency and utilisation are meaningful and that overhead absorption rates are based on realistic production levels.
CAS-3 – Production and Operation Overheads
The third standard deals with determining and assigning production or operation overheads consistently. These are indirect costs associated with manufacturing goods or providing services that cannot be directly traced to a single product, service, or job.
The scope applies to cost statements involving the classification, measurement, assignment, presentation, and disclosure of production or operation overheads. This includes overheads such as indirect labour, indirect materials, factory rent, depreciation on plant and machinery, and maintenance costs.
The standard prescribes detailed disclosure requirements. These include the basis used for assigning overheads to cost objects, any overheads incurred in foreign currency, transactions with related parties involving overhead costs, subsidies or incentives received, credits or recoveries related to overheads, and abnormal costs excluded from overhead computation. It also covers the disclosure of unabsorbed overheads, which may occur when actual production is lower than the capacity on which absorption rates are based. Disclosures are required only when the information is material, significant, and quantifiable. This ensures transparency and prevents distortion of product costs.
CAS-4 – Cost of Production for Captive Consumption
This standard sets out principles for determining the cost of goods or services that are produced and used internally rather than sold to customers. Captive consumption is common in integrated operations where intermediate products are transferred to other divisions or units within the same organisation.
The scope includes determining the cost of producing goods, acquiring goods, supplying goods or services, and valuing them at open market value or at the price of goods or services of like kind and quality. This standard is particularly relevant for compliance with GST provisions, where valuation for captive consumption is required for tax purposes.
By applying consistent methods for determining cost, organisations can ensure that internal transfers are priced appropriately, enabling better cost control and accurate performance evaluation for different divisions. It also prevents under- or overstatement of values in statutory records and ensures compliance with regulatory requirements.
CAS-5 – Average (Equalised) Cost of Transportation
The fifth standard addresses the need to determine average transportation costs in a systematic and transparent manner. Transportation costs can vary widely depending on the distance, route, mode of transport, and load factors. This standard provides guidance on averaging these costs to achieve equitable allocation.
Its objectives include standardising methods for computing average transportation cost, prescribing record-keeping systems for collecting and allocating transportation costs, and promoting transparency in how these costs are determined. The scope includes a range of applications such as excise duty valuation, insurance claim settlement, freight subsidy claims, administered pricing systems, inclusion of inward freight costs in purchase cost, and valuation of inventory for accounting or hypothecation purposes.
By following this standard, organisations can ensure that transportation costs are spread fairly across products, locations, or cost centres, reducing the risk of cost distortion and ensuring consistency in pricing and valuation.
CAS-6 – Material Cost
Material cost is a key component of most manufacturing and many service activities. CAS-6 sets out the principles for determining material costs with accuracy and consistency, ensuring that cost statements present a true reflection of resource usage.
The scope covers the classification, measurement, assignment, presentation, and disclosure of material costs in cost statements. Material costs include not only the purchase price of raw materials but also duties, transportation, handling charges, and other expenses directly attributable to bringing the materials to their present location and condition. Adjustments for trade discounts, rebates, and any abnormal losses or wastages are also considered.
Accurate material costing is critical for determining product costs, valuing inventory, and analysing material efficiency. This standard provides a framework that helps organisations apply consistent valuation methods, whether materials are purchased from external suppliers or transferred internally.
CAS-7 – Employee Cost
The seventh standard focuses on employee-related costs, which can be a substantial portion of total costs in many industries. Employee costs encompass all forms of remuneration and benefits provided to employees, whether monetary or non-monetary.
Its scope applies to cost statements that require classification, measurement, assignment, presentation, and disclosure of employee costs. The standard covers wages, salaries, bonuses, incentives, contributions to social security schemes, employee welfare expenses, training costs, and other benefits.
By including all relevant costs, organisations gain a complete picture of the human resource cost burden. This supports better planning for workforce requirements, budgeting, and performance measurement. The standard also promotes transparency in reporting employee costs, ensuring that they are appropriately allocated to products, services, or cost centres.
CAS-8 – Cost of Utilities
The eighth standard addresses the cost of utilities such as power, water, steam, gas, and compressed air, which are essential inputs in many production processes and service operations. Utilities can be generated internally or purchased externally, and their cost must be determined accurately for proper cost allocation.
The scope includes cost statements requiring classification, measurement, assignment, presentation, and disclosure of utility costs. This standard is not applicable to organisations whose primary business is the generation and sale of utilities, as their costs are determined under different accounting frameworks. It also does not cover the treatment of carbon credits, which is addressed separately.
Applying this standard ensures that utility costs are measured consistently, enabling accurate product costing and efficiency analysis. Proper allocation of utility costs can reveal opportunities for cost savings and efficiency improvements in production processes.
CAS-9 – Packing Material Cost
Packing materials play an important role in protecting and preserving goods during transportation and storage. CAS-9 outlines the principles for determining the packing material cost to ensure uniformity and accuracy in cost statements.
This standard applies to cost statements that require classification, measurement, assignment, presentation, and disclosure of packing material costs. The scope includes primary packing materials that come in direct contact with the product, such as bottles, cans, wrappers, and secondary packing materials like cartons and pallets.
The standard requires that the cost of packing materials should include purchase price, transportation, handling, and any other costs directly attributable to bringing the materials to their present location and condition. Adjustments must be made for trade discounts, rebates, and any abnormal losses or wastage during handling or storage.
Accurate packing material cost determination is vital for product pricing, inventory valuation, and cost control. By following this standard, companies can avoid under- or overstatement of packing costs, which can significantly affect the profitability of products.
CAS-10 – Direct Expenses
Direct expenses are costs that can be specifically identified and directly traced to a cost object such as a product, job, or service. CAS-10 provides guidance on determining direct expenses consistently.
The scope covers cost statements requiring classification, measurement, assignment, presentation, and disclosure of direct expenses. Examples include special tooling charges, royalties, licence fees, technical fees directly related to production, and expenses incurred for specific contracts.
The standard emphasises that direct expenses should be charged in full to the cost object to which they relate, ensuring precise cost determination. Indirect or shared expenses should not be classified as direct expenses.
By applying this standard, organisations can maintain transparency in direct expense reporting, facilitating accurate costing and profitability analysis for individual products or projects.
CAS-11 – Administrative Overheads
Administrative overheads consist of expenses incurred in managing the organisation as a whole, which cannot be directly linked to any particular product or service. CAS-11 sets out principles for the consistent determination and allocation of administrative overheads.
The scope includes cost statements that require classification, measurement, assignment, presentation, and disclosure of administrative overheads. These may include salaries of administrative staff, office rent, depreciation of office equipment, and professional fees.
The standard requires that administrative overheads be allocated to cost centres or cost objects based on a rational and consistent basis, such as employee strength, floor space occupied, or other appropriate drivers.
Consistent application of this standard ensures that overheads are fairly distributed, preventing distortion in product or service costing and enabling better management control over administrative expenses.
CAS-12 – Repairs and Maintenance
Repairs and maintenance costs are incurred to keep plant, machinery, equipment, and buildings in working condition. CAS-12 provides guidelines for determining these costs accurately.
Applicable to cost statements involving classification, measurement, assignment, presentation, and disclosure of repair and maintenance costs, this standard includes routine maintenance, overhaul, servicing, and repairs of production assets.
The standard distinguishes between normal maintenance expenses, which should be treated as revenue expenses, and major repairs or capital expenditure, which should be capitalised and depreciated.
Accurate treatment of repair and maintenance costs helps organisations maintain reliability in asset management and ensure proper allocation of these costs in product or service costing.
CAS-13 – Cost of Service Cost Centre
Service cost centres are departments or units that provide services supporting production but do not directly manufacture goods or services. CAS-13 outlines the principles for determining the cost of such centres.
The scope covers the preparation and presentation of cost statements involving classification, measurement, and assignment of service cost centre costs. Examples include maintenance departments, power plants, quality control laboratories, and tool rooms.
The standard mandates that all costs incurred by service centres should be accurately captured and assigned to appropriate cost objects based on reasonable and consistent bases such as machine hours, labour hours, or quantity of service provided.
By applying this standard, organisations can ensure that service centre costs are properly reflected in product or service costing, supporting more accurate pricing and profitability analysis.
CAS-14 – Pollution Control Cost
Environmental compliance and pollution control have become critical responsibilities for many industries. CAS-14 establishes uniform principles for determining pollution control costs.
This standard applies to cost statements requiring classification, measurement, assignment, presentation, and disclosure of pollution control expenses. Such costs include investment in pollution control equipment, operation and maintenance of pollution control systems, and expenses related to environmental audits and compliance.
The standard distinguishes between capital and revenue nature of pollution control costs and prescribes their appropriate accounting treatment. Capital costs may be depreciated over the useful life of the assets, while operational expenses are charged to cost as incurred.
Consistent application of this standard enables organisations to reflect environmental costs fairly in product or service costs, aiding in better decision-making and regulatory compliance.
CAS-15 – Selling and Distribution Overheads
Selling and distribution overheads include costs incurred in marketing, selling, and distributing products. CAS-15 provides guidelines for determining these overheads in a uniform manner.
The scope covers classification, measurement, assignment, presentation, and disclosure of selling and distribution expenses. Examples include advertising, sales commission, warehousing, freight outwards, and salaries of sales staff.
The standard requires that selling and distribution overheads be allocated to cost objects based on logical and consistent criteria, such as sales volume, number of transactions, or area served.
Adhering to this standard helps organisations accurately assess the cost of marketing and distribution activities, enabling more precise pricing strategies and profitability evaluation.
CAS-16 – Depreciation and Amortisation
Depreciation and amortisation represent the systematic allocation of the cost of tangible and intangible assets over their useful lives. CAS-16 lays down principles for determining depreciation and amortisation costs consistently.
The scope includes cost statements requiring measurement, assignment, presentation, and disclosure of depreciation and amortisation expenses. This standard covers both tangible fixed assets like machinery and buildings, as well as intangible assets such as patents and technical know-how.
The standard prescribes that depreciation should be based on the cost of the asset, its estimated useful life, and its residual value, using a method that reflects the pattern of consumption of benefits. Common methods include straight-line and written-down value approaches.
For amortisation of intangible assets, the standard suggests systematic allocation over the period in which the asset is expected to generate benefits.
Accurate determination of depreciation and amortisation ensures that product and service costs reflect the true consumption of assets, supporting fair pricing and effective asset management.
CAS-17 – Interest and Financing Charges
Interest and financing charges form an important component of the overall cost structure, especially for capital-intensive industries. CAS-17 lays down principles for the consistent determination and assignment of interest and financing charges to cost objects.
This standard applies to cost statements that require classification, measurement, assignment, presentation, and disclosure of interest and financing expenses. Typical charges include interest on borrowed funds, bank charges related to financing activities, and other costs incurred in raising capital.
However, CAS-17 excludes costs related to risk management activities conducted through derivative instruments, as these are governed by different accounting frameworks.
The standard emphasises assigning interest and financing charges to cost centres or cost objects based on reasonable and consistent allocation methods, such as the use of funds, period of usage, or proportional cost drivers.
Proper application ensures that financing costs are accurately reflected in product or service costs, supporting effective pricing and investment decisions.
