Definition of Cost Accounting
Cost Accounting is a branch of accounting that involves recording, classifying, analyzing, and allocating costs associated with a process, product, or service. It helps businesses determine the cost of production, control expenses, and support decision-making to maximize profitability.
Meaning of Cost Accounting in Detail
Cost Accounting goes beyond traditional financial accounting. While financial accounting focuses on presenting the overall financial position of a company, cost accounting zooms in on internal cost data. It evaluates direct and indirect expenses to provide management with information for controlling operations, setting prices, and improving efficiency.
For example, a car manufacturing company uses cost accounting to determine the cost per vehicle, factoring in raw materials, labor, and overheads. This enables them to decide selling prices, control waste, and optimize resource utilization.
Sub-Sections of Cost Accounting
Direct Costs
These are costs directly traceable to a product, such as raw materials and direct labor.
Indirect Costs (Overheads)
Expenses that cannot be traced directly, such as electricity, rent, and salaries of supervisors.
Fixed Costs
Costs that do not vary with output (e.g., factory rent).
Variable Costs
Costs that fluctuate with production volume (e.g., raw material usage).
Semi-Variable Costs
Costs that have both fixed and variable components, such as utility bills.
Formula of Cost Accounting
The basic cost calculation formula is:
Cost of Production = Direct Material + Direct Labor + Direct Expenses + Factory Overheads + Administrative Overheads + Selling & Distribution Overheads
Example Calculation of Cost Accounting
Suppose a company produces 1,000 units of product:
-
Direct Material: ₹200,000
-
Direct Labor: ₹100,000
-
Direct Expenses: ₹50,000
-
Factory Overheads: ₹80,000
-
Administrative Overheads: ₹40,000
-
Selling & Distribution Overheads: ₹30,000
Total Cost of Production = ₹200,000 + ₹100,000 + ₹50,000 + ₹80,000 + ₹40,000 + ₹30,000 = ₹500,000
Cost per Unit = ₹500,000 ÷ 1,000 = ₹500 per unit

Detailed Illustration Calculation
If a company produces 500 chairs:
-
Direct Material = ₹150,000
-
Direct Labor = ₹75,000
-
Factory Overhead = ₹50,000
Total = ₹275,000
Cost per Chair = ₹275,000 ÷ 500 = ₹550 per chair
If chairs are sold at ₹700 each, Profit per Chair = ₹700 – ₹550 = ₹150.
