How it works

Contribution per order = AOV x (1 - product cost % - fees % - refund %) - shipping per order

Contribution per order is what one order leaves you before ads. It is also your break-even CPA: pay more than this to win an order and that order loses money.

Break-even ROAS = AOV / contribution per order

Net profit is contribution times orders, minus ad spend and fixed costs.
