CONTRIBUTION MARGIN
Back to GlossaryDefinition
Revenue minus variable costs; the amount available to cover fixed costs and contribute to profit.
Summary
Contribution margin is a key financial metric that shows how much money remains from sales revenue after paying for variable costs (costs that change with production volume). Think of it as the 'contribution' each sale makes toward paying fixed costs (like rent, salaries) and generating profit. It's calculated as: Contribution Margin = Revenue - Variable Costs. This metric helps businesses understand the profitability of individual products and make decisions about pricing, production levels, and product mix.
Usage Context
Understanding contribution margin is crucial when analyzing profitability, making break-even calculations, deciding which products to emphasize, setting prices, and evaluating the impact of volume changes on profits.
Common Confusions
- Confusing contribution margin with gross profit (gross profit includes some fixed costs)
- Thinking all costs are either fixed or variable (some costs are mixed)
- Assuming contribution margin equals profit (it doesn't account for fixed costs)
- Mixing up contribution margin ratio with contribution margin dollar amount
- Forgetting that contribution margin changes with volume while the ratio stays constant
