What is Absorption Costing?
Absorption Costing, also called Full Costing or Total Absorption Costing, is a product costing method under which all manufacturing costs — both fixed and variable — are included in the cost of a unit of product. Unlike marginal costing, it does not separate fixed costs and treat them as period costs.
Absorption costing is the standard method required for external financial reporting under Indian GAAP (AS 2) and Ind AS (Ind AS 2 — Inventories). It ensures that inventory on the balance sheet reflects the full cost of production.
Components of Absorption Cost
- Direct Materials: Raw materials directly traceable to each unit of product
- Direct Labour: Wages of workers directly involved in manufacturing
- Variable Manufacturing Overhead: Costs that vary with production volume — consumables, power, factory supplies
- Fixed Manufacturing Overhead: Costs that remain constant regardless of output — factory rent, depreciation on machinery, supervisory salaries
Absorption Costing Formula
Absorption Cost per Unit = (Direct Materials + Direct Labour + Variable Overhead + Fixed Overhead) ÷ Units Produced
Practical Example
A company produces 10,000 units in a month:
- Direct Materials: ₹5,00,000
- Direct Labour: ₹2,00,000
- Variable Overhead: ₹1,00,000
- Fixed Overhead: ₹2,00,000
Total Cost = ₹10,00,000 | Cost per Unit = ₹100
If 8,000 units are sold and 2,000 remain as closing stock:
- COGS = 8,000 × ₹100 = ₹8,00,000
- Closing Inventory = 2,000 × ₹100 = ₹2,00,000 (shown on Balance Sheet)
Absorption Costing vs Marginal Costing
| Aspect | Absorption Costing | Marginal Costing |
|---|---|---|
| Fixed overhead treatment | Included in product cost | Treated as period cost (charged to P&L) |
| Required for | Financial reporting (Ind AS, GAAP) | Internal management decisions only |
| Profit with rising inventory | Higher (fixed costs deferred in stock) | Lower (fixed costs fully expensed) |
| Break-even analysis | Less suitable | More suitable |
Under-Absorption and Over-Absorption
When actual production differs from budgeted production, the fixed overhead absorbed may differ from actual fixed overhead incurred:
- Under-absorption: Actual overhead > Absorbed overhead — charged as additional expense to P&L
- Over-absorption: Absorbed overhead > Actual overhead — credited to P&L
📌 Ind AS 2 Requirement: Inventories must be valued at the lower of cost (using absorption costing) and net realisable value (NRV). This applies to all companies following Ind AS — typically listed companies and large unlisted companies.
