Marginal and Absorption Costing

Two Ways to Treat Costs

Marginal costing and absorption costing are two different approaches to costing products.

Marginal Costing

  • Only variable costs are charged to products.
  • Fixed costs are treated as period costs (expenses).

Absorption Costing

  • Both variable and fixed costs are assigned to products.
  • Used for external financial reporting.

Key Differences

  • Marginal costing aids short-term decision-making.
  • Absorption costing gives a complete picture of product costs.

Application

Marginal costing helps managers decide whether to accept special orders or discontinue a product line, while absorption costing ensures accurate profit reporting.

Marginal Cost Formula

\[ \text{Marginal Cost} = \frac{\Delta \text{Total Cost}}{\Delta \text{Quantity}} \]

Key Formula

\[\text{Marginal Cost} = \frac{\Delta \text{Total Cost}}{\Delta \text{Quantity}}\]

Examples

  • A toy company uses marginal costing to decide if it should accept a bulk order at a lower price.

  • A food manufacturer uses absorption costing to report inventory values in its financial statements.

In a Nutshell

Marginal costing focuses on variable costs, while absorption costing includes all costs.
