- Contribution per order = average order value − variable cost per order
- Break-even orders = fixed costs ÷ contribution per order
- Break-even ROAS = 1 ÷ contribution margin. Below this, every ad-driven sale loses money.
- Max CPA = contribution per order: the most you can spend to win one order and still break even on it.
Repeat purchases change the picture. If customers buy three times a year, you can afford a higher first-order CPA, as long as you have the cash flow. Use the profit margin calculator to work out your variable cost per order.
