Contribution Margin subtracts all variable costs from the selling price: COGS, shipping fees, payment commissions, platform fees. Formula: CM = Selling Price - Variable Costs. On a $100 order with $60 in variable costs, the CM is $40 (40%). This is the margin left to cover fixed costs and generate profit. It's the key metric for evaluating unit-level profitability.
