What is Break-Even ROAS?

Break-even ROAS is the return on ad spend at which your ads exactly cover their cost - below it you lose money, above it you profit. It's the single most useful number for judging campaigns, and it's set entirely by your profit margin: the thinner your margin, the higher the ROAS you need. Enter your margin (and optionally your average order value) to see your break-even line.

Frequently asked questions

How do I calculate break-even ROAS?

Divide 1 by your profit margin expressed as a decimal. A 40% margin gives a break-even ROAS of 1 ÷ 0.40 = 2.5x. Any ROAS above 2.5x is profit; below it, you're paying to lose money.

What margin should I use?

Use your true contribution margin - price minus product cost, shipping, payment fees and any per-order costs - not just the retail markup. Using an inflated margin makes your break-even ROAS look easier than it is and quietly loses money.

Why is break-even ROAS more useful than a target ROAS?

A 'good' ROAS is meaningless without your margin. Break-even ROAS turns your economics into one clear line you can hold every campaign to. Clicked shows your actual blended ROAS by source so you can see which channels clear that line.
