To calculate break-even ROAS, enter your order economics — selling price, product cost, transaction or platform fees, and any target profit per order. The Break-Even ROAS Calculator then derives the return on ad spend at which one order exactly covers its costs, expressed both as a ratio (for example 2.5x) and as a percentage.
Break-even ROAS is clearer than a generic ROAS number because it starts from your real costs and margin rather than a guessed target. It tells you the ceiling: spend more per order than this and that order loses money. The calculation runs entirely in your browser, so nothing is uploaded.
A general ROAS calculator is easy to misuse because it does not anchor to your margin. A break-even calculator is clearer: it starts from costs, margin, and the real ad-spend ceiling per order, which is the number that actually decides whether a campaign is sustainable.
In this simple version, the maximum ad spend per order matches the maximum customer acquisition cost (CAC) one order can support before it stops breaking even. That makes it a quick sanity check before scaling spend on a product.

Break-even ROAS is the return on ad spend at which one order's revenue exactly covers its product cost, fees, and any target profit — the point where the order neither gains nor loses money.
