ROAS Calculator

How to use this tool

1. Enter your total ad spend for the period — the money that actually went to the ad platforms.
2. Enter the total revenue those ads generated. Only count revenue you can genuinely attribute to the ads, not your whole business turnover.
3. Read your ROAS instantly. Open advanced options to add conversions, your profit margin and a platform benchmark for a sharper picture.

How ROAS is calculated

ROAS is simple: revenue divided by ad spend. Spend $5,000 and make $20,000 back and your ROAS is 4.00x — four dollars of revenue for every dollar you put in. That's the headline number, and it's the one most people stop at.

The catch is that revenue isn't profit. A 4.00x ROAS on a product with a 25% margin is barely breaking even once you account for the cost of the goods. That's why this tool lets you add your gross profit margin: it works out your breakeven ROAS — the point where the ads stop costing you money — and tells you plainly whether you're above or below it.

ROAS is not profit

Say it again for the people up the back. ROAS measures revenue against ad spend and nothing else. It ignores your product costs, your team, your platform fees and everything else it takes to run the business. It's a useful gauge of ad efficiency, not a measure of whether you're making money. Use it alongside your margins, not instead of them.
