Revenue minus all variable costs per unit, showing how much each sale contributes to covering fixed costs.
Contribution Margin = Revenue - Variable CostsContribution margin measures how much revenue from each sale is available to cover fixed costs and generate profit, after deducting all variable costs (COGS, shipping, payment fees, packaging).
Contribution margin helps you understand the true profitability of each product or order. A product with a high selling price but also high variable costs may contribute less than a cheaper product with lower costs.
You can calculate contribution margin per unit (for product-level decisions) or as a total (for business-level analysis).
Product sells for $40. Variable costs (COGS $15 + shipping $5 + fees $2) = $22. Contribution margin = $18 per unit.
