Break-even ROAS, explained
ROAS (return on ad spend) is revenue divided by ad cost. It only tells you whether ads are profitable once you know your gross margin: at a 40% margin you need 2.5x ROAS just to break even. The calculator shows clicks, conversions, revenue, CPA and profit from your budget — and how much a half-point lift in conversion rate changes the result, which is why landing page work often beats a bigger budget.
