ROAS calculator

See how much revenue each unit of ad spend brings back, and whether that is enough to make a profit.

Your numbers

Ad spendWhat you paid the ad platform

Revenue from these adsSales your tracking attributes to the ads

Gross margin (optional)Share of revenue left after product or delivery costs. Needed for break-even.

How it works

ROAS = revenue ÷ ad spend
Break-even ROAS = 1 ÷ gross margin

A ROAS of 4× means every 1 spent brought back 4 in revenue. Revenue isn't profit, though: with a 25% margin you need at least 4× just to cover the ads. That's why the break-even number matters more than a "good ROAS" rule of thumb.
