About ROAS Calculator

Why we built this

Most ad platforms will hand you a ROAS number, but they won't tell you whether that number is actually good enough for your business. A 3x ROAS can be a great result for one store and a slow bleed of cash for another, depending entirely on the profit margin behind it. We built ROAS Calculator to close that gap — a free tool that turns "is my ROAS good?" into a specific, calculable answer, in seconds, without opening a spreadsheet.

What we do

ROAS Calculator gives you two ways to look at your numbers. The quick calculator takes your ad spend, revenue and (optionally) your profit margin, and instantly returns your ROAS, ROI, profit and break-even ROAS. The campaign comparison table lets you weigh multiple campaigns, promo codes or influencers side by side, with sorting and a target-ROAS flag so you can see at a glance what to scale and what to pause. Everything runs in your browser — no account, no signup, no spreadsheet required.

How we keep the numbers honest

Every formula on this site — ROAS, ROI, break-even ROAS — is the same standard definition used across the advertising and finance industry, not a proprietary metric we invented. We'd rather you understand exactly how a number was calculated than have to trust a black box, so the reasoning behind each calculation is explained in plain language in the What is ROAS section.

Your data stays yours

Nothing you type into ROAS Calculator — ad spend, revenue, campaign names — ever leaves your browser. There's no server-side tracking of your numbers, no login, and no data to leak. See our Privacy Policy for the full details.

Who's behind it

ROAS Calculator is an independently built and maintained tool — one of a small set of free, focused web utilities made by a solo developer who'd rather ship something useful than something bloated. If you spot something wrong with a formula or a rough edge in the tool, we want to hear about it.
