# Break-even ROAS calculator

Your margin in, the ROAS you need to stop losing money out. Any number solves for the rest.

## How it works

Enter your profit margin and the break-even ROAS calculator tells you the return on ad spend you need before an ad stops losing you money. Add your spend and revenue to see where you stand.

The maths is simple: break-even ROAS is 1 divided by your margin. At a 25% margin you need €4 back for every €1 on ads.

## FAQs

Break-even ROAS = 1 ÷ profit margin. A 40% margin means you need a ROAS of 2.5.

### What is ROAS?

Return on ad spend: the revenue from your ads divided by what you spent on them.

### What margin should I use?

What you keep from a sale after product costs, shipping and payment fees, before ad spend.
