ROAS Calculator

ROAS calculator that turns ad spend and revenue into your return on ad spend, then checks it against your break-even ROAS so you know whether the campaign actually makes money. Free, no signup.

ROAS = revenue from ads / ad spend. $1,500 in sales from $500 of ads is a 3x ROAS, or 300%. It measures revenue, not profit: with a 30% margin before ads, the same 3x campaign loses money, because break-even ROAS is 1 divided by the margin (3.33x at 30%, 2x at 50%).

Aim for 1.5 to 2 times your break-even ROAS to cover refunds, chargebacks and the ad sets that do not work.
