Cost Allocation

 

Cost Allocation – Definition

Cost Allocation is the process of identifying, aggregating, and assigning costs to specific cost objects such as departments, products, projects, or services in a business.

Meaning of Cost Allocation

In simple terms, cost allocation means dividing business expenses among different parts of the company that benefit from those expenses. It ensures that every department, product, or project bears its fair share of the total cost.

For example, if your company spends ₹1,00,000 on electricity, you don’t record it as a single lump sum expense—you distribute the cost to different departments based on their electricity usage. This way, you get an accurate picture of each department’s expenses and profitability.

Practical Example

Imagine ABC Manufacturing Ltd. uses one central printing facility for three departments:

• Department A prints 5,000 pages per month

• Department B prints 3,000 pages

• Department C prints 2,000 pages

The monthly printing cost is ₹10,000.

Using cost allocation, the expenses will be divided proportionally:

• Dept A → ₹5,000

• Dept B → ₹3,000

• Dept C → ₹2,000

Cost Allocation in the Indian Financial System

In India, cost allocation is important for:

• Tax computation – Accurate allocation ensures expenses are properly matched to revenue for GST and Income Tax purposes.

• Cost Audit – As per the Companies (Cost Records and Audit) Rules, 2014, certain companies must maintain detailed cost records showing allocation to each product or service.

• Transfer Pricing – When allocating costs between related parties, businesses must comply with Indian transfer pricing laws under the Income-tax Act, 1961.

Why It’s Important

• Accurate Profitability Analysis – Identifies which products or services are truly profitable.

• Cost Control – Helps detect wastage and inefficiencies.

• Tax Compliance – Proper allocation reduces risk of disputes with tax authorities.

• Decision-Making – Supports fair budgeting and pricing strategies.

Formula for Cost Allocation

The basic formula is:

$$\text{Allocated Cost} = \frac{\text{Base Usage of Cost Object}}{\text{Total Base Usage}} \times \text{Total Cost}$$

Where:

• Base Usage could be machine hours, labor hours, square footage, etc.

• Total Cost is the overall expense to be allocated.

Journal Entry Example

Scenario:
Company pays ₹50,000 for factory rent to be allocated between Dept A and Dept B in a 60:40 ratio.

Journal Entry:

Dept A Expense A/c      Dr ₹30,000  
Dept B Expense A/c      Dr ₹20,000  
      To Rent Payable A/c           ₹50,000  
(Being rent allocated between departments in the ratio 60:40)  

Accounting Illustration

Scenario:
Total electricity bill: ₹1,20,000 per month
Allocation base: Number of machines used

Department	Machines	% of Total Machines	Allocated Cost
Dept A	6	60%	₹72,000
Dept B	4	40%	₹48,000
