Free ad math

Ad spend calculators for the numbers you check every day

ROAS, CPC, CPM, CTR, and AOV in one place — type your numbers, get an instant answer, and see what the result actually means before you decide what to do next.

Why these tools exist

Every one of these numbers already lives inside your ads dashboard, buried a few clicks deep in a report you have to build yourself. That's fine when you check it once a week. It's not fine when you're mid-decision — should this campaign get more budget, is this hook worth a variant, is this launch actually profitable — and you need the number now, without exporting anything.

So this page keeps five calculations on one screen: type two numbers, get the answer, and read a plain-language note about what that number is telling you. No login, no spreadsheet, nothing saved anywhere — just the math, done in your browser the moment you type.

If you'd rather skip straight to the one you need, use whichever calculator matches the decision in front of you: ROAS when you're weighing whether a campaign deserves more budget, CPC or CPM when a campaign feels expensive before it's even converting, CTR when you're not sure the creative itself is working, and AOV when you're trying to work out how much room your margin gives your ad spend. Bookmark this page and come back whenever one of those questions comes up — the numbers change weekly, the questions don't.
