Cost Accounting Standard (CAS) 21: Costs of Production – Allocation, Classification, and Compliance

Introduction to CAS 21

Cost Accounting Standard (CAS) 21 focuses on the allocation and classification of production costs in cost accounting. It provides guidance on how production costs should be identified, allocated, and disclosed to ensure consistency and transparency in financial reporting.

In this article, we will cover:

• The scope and applicability of CAS 21
• Key definitions and principles
• Classification and allocation of production costs
• Compliance and disclosure requirements
• Practical examples for better understanding
• FAQs for clarification

Scope and Applicability of CAS 21

CAS 21 applies to all industries involved in manufacturing or producing tangible goods, including:

• Automobile manufacturing
• Electronics and electrical goods
• Textiles and garments
• Chemicals and pharmaceuticals

It is not applicable to service industries or industries engaged in producing intangible assets.

Key Definitions Under CAS 21

1. Production Costs

Production costs are the costs incurred in the process of manufacturing goods, including materials, labor, and overheads.

Example: A garment factory incurs costs for raw materials (fabric), labor (stitching), and factory overheads (electricity).

2. Direct Costs

Costs directly attributable to the production process. These include raw materials, direct labor, and any costs related to the specific goods produced.

Example: The cost of raw materials used to make a specific type of automobile part.

3. Indirect Costs

These costs are incurred for the production process but cannot be directly traced to a specific product. They include factory overheads, such as rent, utilities, and depreciation on machinery.

Example: The cost of electricity used in the factory.

Principles of Allocation and Classification of Production Costs

1. Direct Cost Allocation

Direct costs are allocated directly to the production process. These costs can be traced specifically to a product or service.

Formula:
Direct Production Cost = Sum of All Direct Costs

Example:
If a company spends ₹15,00,000 on raw materials and ₹5,00,000 on direct labor for producing 100,000 units, the total direct production cost is ₹20,00,000.

2. Indirect Cost Allocation

Indirect costs are distributed across all products based on an allocation method. These costs include rent, utilities, and factory management salaries.

Methods for allocating indirect costs include:

• Based on machine hours used
• Based on labor hours
• Based on units produced

Formula:
Allocated Indirect Cost = (Product-Specific Allocation Base ÷ Total Allocation Base) × Total Indirect Costs

Example:
If a company spends ₹30,00,000 on factory overheads and produces 10,000 units, then the indirect cost allocated to each unit is ₹3,000.

Classification of Production Costs in CAS 21

1. Raw Material Cost

The cost of materials directly used in the production process, such as:

• Raw materials – The basic materials used to create a product
• Consumables – Items used in the production process but not forming part of the final product

2. Direct Labor Cost

The wages and salaries of employees directly involved in the production process, such as:

• Factory workers
• Machine operators

3. Factory Overheads

Costs that are necessary for the production process but cannot be directly attributed to a product. These include:

• Depreciation of machinery
• Factory rent
• Utilities (electricity, water)

4. Selling, General, and Administrative (SG&A) Costs

While not part of production costs, CAS 21 may require separate reporting of these expenses.

---

Compliance and Disclosure Requirements Under CAS 21

1. Disclosure of Production Costs

CAS 21 requires organizations to disclose the total production costs for a given period. This includes:

• Direct and indirect costs
• Allocated overheads
• The methodology used for allocation

2. Detailed Disclosure of Methods

The company must disclose how it allocates indirect costs and the basis for such allocation (e.g., machine hours, labor hours).

3. Impact on Financial Statements

CAS 21 ensures that production costs are accurately reflected in the financial statements, impacting:

• Profitability analysis
• Inventory valuation
• Cost control strategies

---

Practical Example of Production Cost Allocation

Let’s consider a textile manufacturing company that produces 50,000 units of clothing in a given period. The company incurs the following costs:

• Direct raw material cost: ₹8,00,000
• Direct labor cost: ₹4,00,000
• Factory overhead (indirect): ₹3,00,000

The company produces 50,000 units, so:

• Direct cost per unit = (₹8,00,000 + ₹4,00,000) ÷ 50,000 = ₹240 per unit
• Indirect cost per unit = ₹3,00,000 ÷ 50,000 = ₹60 per unit
• Total production cost per unit = ₹240 (direct cost) + ₹60 (indirect cost) = ₹300 per unit

Common Mistakes in Applying CAS 21 (And How to Avoid Them)

1. Incorrectly Allocating Indirect Costs

Mistake: Allocating indirect costs equally across products.
Solution: Use a more accurate allocation method like machine hours, labor hours, or units produced.

2. Misclassifying Costs

Mistake: Mixing direct costs with indirect costs.
Solution: Properly identify costs and assign them to the correct category.

3. Not Disclosing Production Costs Clearly

Mistake: Failing to provide clear disclosure of methodologies and cost allocation bases.
Solution: Ensure transparency by following CAS 21 guidelines for disclosures.

Frequently Asked Questions (FAQs) on CAS 21

Q1: What are production costs?

Production costs are the expenses directly associated with manufacturing goods, including raw materials, labor, and overheads.

Q2: How should indirect costs be allocated?

Indirect costs should be allocated using a systematic method, such as machine hours, labor hours, or units produced.

Q3: What does CAS 21 require for compliance?

CAS 21 mandates that companies disclose production costs and the methods used for allocating indirect costs.

Q4: Can overheads be allocated based on revenue?

While revenue-based allocation is not common in CAS 21, cost allocation should reflect actual resource usage.

Q5: How does CAS 21 impact financial statements?

CAS 21 ensures that production costs are accurately reported, affecting profitability analysis and inventory valuation.
