Frequently asked questions

Why can a high ROAS still lose money?

ROAS only compares revenue with ad spend. It does not know your COGS, shipping, payment fees, returns or other costs.

What happens below break-even ROAS?

If the assumptions are correct, advertising cost consumes more than the available contribution and the order becomes contribution-negative.

Should overhead be included?

For a fuller business break-even target you may also allocate overhead and other fixed costs. This free tool focuses on order-level variable contribution.
