What Is Contribution Margin?

Contribution margin is the amount of revenue remaining after all variable costs are subtracted. It is the portion of each sale that "contributes" toward covering fixed costs and generating profit. Understanding your contribution margin is essential for pricing decisions, product mix analysis, and break-even calculations. A business with a high contribution margin can absorb fixed costs more easily and reaches profitability at lower sales volumes than one with a low contribution margin.

What Counts as a Variable Cost?

Contribution Margin Formula

Contribution Margin ($) = Sales Revenue − Variable Costs
Contribution Margin (%) = (Sales Revenue − Variable Costs) ÷ Sales Revenue × 100

Contribution Margin Example

Sales Revenue: $100,000  |  Variable Costs: $60,000
Contribution Margin = $100,000 − $60,000 = $40,000
Contribution Margin % = $40,000 ÷ $100,000 × 100 = 40%

Contribution Margin and Break-Even

Contribution margin is the key input in break-even analysis. The break-even point in revenue is calculated as Fixed Costs divided by the Contribution Margin Percentage. If your fixed costs are $40,000 and your contribution margin is 40 percent, you need $100,000 in revenue to break even. Every dollar of revenue above that threshold generates $0.40 in profit. This relationship makes contribution margin one of the most practically useful metrics for financial planning at any business size.
