ROAS vs. break-even ROAS

ROAS on its own is a vanity metric — it tells you nothing until you compare it to what you actually need. Break-even ROAS is 1 ÷ your gross margin: at a 50% margin you need 2× just to cover the spend, at 33% margin you need 3×. The gap between your ROAS and your break-even is where profit lives. This calculator surfaces both so you know whether a campaign is a scale candidate or a leak.

How to use the numbers

• Above break-even: the campaign is profitable — a candidate to scale budget on.
• At break-even: every extra point of ROAS is pure profit; a stronger hook or offer is the fastest lever.
• Below break-even: you're losing money on every sale — fix the creative or offer before adding spend.

The cheapest way to lift ROAS is usually more creative testing, not more budget. See the kill/scale rule and how to read your ad metrics.
