ROAS Calculator — free online tool

You spent money on ads and now you want a plain answer: did it pay off? Punching the numbers into a notes app or a calculator is easy to get wrong, and the math behind "break-even" trips most people up. We added a free tool that does it for you — ROAS Calculator — right in your browser.

What it does

You type in how much your ads brought in and how much you spent. It gives you your ROAS (how many times your money came back), your ACoS (the share of revenue eaten by ad cost), and your break-even ROAS — the point where you stop losing money. No formulas to remember, no spreadsheet to set up.

Nothing leaves your device

The whole thing runs in your browser. Your revenue and spend are never uploaded anywhere and nothing is saved. When you close the tab, the numbers are gone. It's just for you.

How to use it

  1. Open ROAS Calculator.
  2. Enter your ad revenue and your ad spend.
  3. Read your ROAS, ACoS and break-even ROAS right away.

It's free with no limit. There are more small tools on the Apps page.
