It takes three inputs — ad spend, the revenue you attribute to those ads, and your gross margin percentage — and returns four numbers. ROAS is revenue divided by ad spend. Break-even ROAS is 1 divided by your margin. Profit on ad spend (POAS) is gross profit divided by ad spend. Net profit is revenue × margin − ad spend.
Plain ROAS is the number most media buyers optimise against and it is the one that lies most often, because it says nothing about what the sale cost you to fulfil. A 2.4× ROAS is a strong month at a 70% margin and a slow bleed at a 30% one. Everything here exists to convert a revenue multiple into a profit answer.
Break-even ROAS = 1 ÷ gross margin. At 60% margin you need 1.67× just to stand still. At 40% you need 2.50×. At 25% you need 4.00×. The calculator computes this from the margin you enter and prints it next to your actual ROAS so the gap is visible at a glance.
The margin field is where you fold in everything the product costs you. If you want shipping, payment fees and returns counted, enter a contribution margin rather than a raw gross margin — the arithmetic does not care which one you feed it, but the verdict is only as honest as that percentage.
The verdict has three states, and the thresholds are deliberate. Profitable requires your ROAS to clear break-even by at least 15%. Break-even covers anything from break-even up to that 15% cushion — mathematically you are ahead, but a result that close sits inside normal week-to-week variance, so treat it as flat rather than as a green light. Losing money is any ROAS below break-even, and the net profit figure shows what the shortfall cost you.
Act on it like this. Clear of break-even by a wide margin? Push budget, then check the saturation curve to see how far you can push before CPA climbs. Sitting in the break-even band? Fix targeting or creative before adding spend — scaling a break-even campaign just buys more break-even. Below the line? Find the campaigns dragging the average down with the budget reallocator before you touch the total budget, and read where Meta ad spend leaks.

FAQ
Break-even ROAS is 1 divided by your gross margin — the return at which the gross profit on a sale exactly pays for the ad that produced it. At a 60% margin it is 1.67×, at 40% it is 2.50×, at 25% it is 4.00×. Below that line every extra dollar of ad spend loses money, no matter how good the ROAS looks in Ads Manager.
It depends entirely on margin. At a 70% margin, 3× is roughly double the 1.43× you need — comfortably profitable. At a 25% margin your break-even is 4.00×, so the same 3× is losing money on every order. That is why this calculator asks for gross margin before it will call a result profitable.
Ads Manager reports platform-attributed revenue under whatever attribution window the account is set to, so it usually credits itself with sales this calculator would not see. Feed it the revenue you can actually tie to the ads — blended or attributed, but pick one and stay consistent so week-to-week comparisons mean something.
