Frequently asked questions
What is break-even ROAS?
It is revenue divided by ad spend at the point where profit is exactly zero. Since ad spend at break-even equals the margin left after product, shipping, and fees, break-even ROAS equals price divided by that margin. Advertise below it and every sale loses money; above it, the surplus is profit.
How does margin relate to break-even ROAS?
They are inverses. Break-even ROAS = 1 / contribution-margin-fraction. A 50% margin breaks even at 2x, 33% at 3x, 25% at 4x, 20% at 5x. The lower your margin, the higher the ROAS your ads must sustain just to avoid losses, which is the core reason cheap, low-margin products are so hard to advertise profitably.
What ROAS should I actually target?
Comfortably above break-even, with a margin of safety for refunds, overhead, and slow days. The target table shows the ROAS each net-profit level requires; many stores aim for a ROAS that leaves at least 15-20% net margin. Break-even is the floor, not the goal.
About this tool
The break-even ROAS calculator finds the return on ad spend at which an order exactly covers its costs — the floor your campaigns must clear before advertising earns anything. It is the inverse of your contribution margin: a 40% margin needs a 2.5x break-even ROAS, a 25% margin needs 4x, which is why thin-margin products demand punishingly efficient ads. Enter your price and costs and it also shows the ROAS required to reach 10%, 20%, and 30% net profit margins, so you can set realistic campaign targets rather than chasing break-even alone. Runs entirely in your browser.
