ROAS Calculator: Return on Ad Spend
Enter ad spend and attributed revenue by channel, your gross margin and a target ROAS. The calculator gives you channel ROAS, blended ROAS, break-even ROAS, profit, and how much you can spend at the target. Compare Meta, Google, and Amazon side-by-side.
ROAS vs break-even ROAS
ROAS tells you revenue per rupee spent. Break-even ROAS tells you the ROAS at which contribution margin equals ad spend. The first is a target; the second is a constraint.
- ROAS = Attributed revenue ÷ Ad spend
- Break-even ROAS = 1 ÷ Gross margin %
- Max spend at target = Revenue ÷ Target ROAS
