Frequently asked questions

What is ROAS?

ROAS is revenue attributed to ads divided by ad spend. Agency fees and other costs belong in Break-even ROAS, not the ROAS denominator.

How is Break-even ROAS calculated?

Break-even ROAS = total cost ÷ (ad spend × gross margin). With no other costs, that equals 1 ÷ margin.
