Understanding Contribution Margin

Key Concepts

Contribution Margin: The amount remaining from sales revenue after variable costs are subtracted. This contributes to covering fixed costs and generating profit.

Variable Costs: Costs that change directly with the level of production or sales volume (materials, direct labor, sales commissions).

Contribution Margin Ratio: The percentage of each sales dollar available to cover fixed costs and profit.

Formulas Used

Contribution Margin = Revenue - Variable Costs

Contribution Margin Ratio = (Contribution Margin ÷ Revenue) × 100

Contribution Margin per Unit = Selling Price - Variable Cost per Unit

Variable Cost Ratio = (Variable Costs ÷ Revenue) × 100
