How the calculator works

Contribution margin is revenue minus cost of goods, shipping and payment fees. It tells you how much each sale leaves before you spend a dollar on ads. Net profit takes ad spend off that. Both are shown as an amount and as a share of revenue, so you can compare months of different sizes. Fixed costs like software and salaries are left out here. Cifra adds them in the app.
