What is Absorption Costing?

A costing method that allocates all manufacturing costs — both fixed and variable — to each product unit, also known as full costing.

How It Works

Absorption costing assigns direct materials, direct labor, variable manufacturing overhead, and fixed manufacturing overhead to every unit produced. This contrasts with marginal costing, which only assigns variable costs. Under absorption costing, fixed overheads are 'absorbed' into inventory cost and expensed only when goods are sold. It is mandatory under Indian Accounting Standards (Ind AS 2), IFRS (IAS 2), and for income tax reporting. The method provides a more complete picture of true product cost but can distort profitability analysis when production volumes fluctuate significantly.

Formula

Unit Cost = Direct Materials + Direct Labor + Variable Overhead + (Fixed Overhead ÷ Units Produced)

Real-World Example

A factory produces 10,000 widgets. Direct material: ₹30/unit, direct labor: ₹20/unit, variable overhead: ₹10/unit, total fixed overhead: ₹2,00,000. Under absorption costing: ₹30 + ₹20 + ₹10 + (₹2,00,000 ÷ 10,000) = ₹80/unit.

Frequently Asked Questions

What is the difference between absorption costing and marginal costing?

Absorption costing includes fixed overheads in product cost; marginal costing treats them as period expenses. Absorption shows higher inventory values and potentially higher profits when production exceeds sales. Marginal costing is better for short-term decision-making.

Why is absorption costing required for financial reporting?

Accounting standards (Ind AS 2, IAS 2, US GAAP) require it because it matches all production costs with revenue when goods are sold, following the matching principle. It prevents understating inventory and overstating expenses.
