How it’s calculated

Fees per order are the platform percentage of the selling price plus any fixed fee. Profit is the selling price minus product cost, fees, shipping and ad cost.

The most you can spend on ads is what is left before ads. Break-even ROAS (return on ad spend) is the selling price divided by that amount: below it, each sale from ads loses money. Platform fees come from our seller fee tables.

Worked example

A $40 item costing $12, with a 15% fee, $0.30 fixed fee and $6 shipping, leaves $15.70 before ads. Spending $8 on ads per order leaves $7.70, a 19.3% margin.
