Find the sweet spot between margin and conversion. Enter your full variable costs (COGS + shipping + packaging + gateway) to calculate contribution margin at different price points — not just gross margin.
Why contribution margin matters: Gross margin (price − COGS) ignores shipping, packaging, and payment gateway fees — which can eat 15-25% of your price. This calculator uses contribution margin (price − all variable costs) so you see your real profit per order. A 50% gross margin can become a 25% contribution margin after costs — that's the difference between scaling and going broke.
