Frequently asked questions

Which margin should I use?

Use your profit margin after product, shipping and fees but before ad costs. That is the share of each sale available to pay for ads.

Can break-even ROAS be below 1?

No. Even at a 100% margin you need at least 1x ROAS to recover what you spent on ads.
