ROAS calculator
ROAS tells you how much revenue each euro of ad spend brings back. On its own it says nothing about profit, so add your margin to see whether you are above break-even.

How it's calculated
- ROAS = revenue from ads / ad spend.
- Break-even ROAS = 1 / gross margin. At 40 % margin it is 2.5.
You spent 1,000 EUR and ads brought 4,000 EUR of revenue. ROAS is 4. With a 40 % margin your break-even ROAS is 2.5, so the ads earn more than they cost.
What is a good value?
- There is no universal good ROAS. It depends entirely on margin.
- At 50 % margin, anything above 2 is profitable. At 20 % margin you need more than 5.
- Aim for a comfortable buffer above break-even, since not all revenue is credited correctly.
Frequently asked questions
What is a good ROAS?
One above your break-even ROAS, which is 1 divided by your margin. A ROAS of 4 is great at 50 % margin and a loss at 20 %.
Is ROAS the same as ROI?
No. ROAS uses revenue, ROI uses profit. ROAS can look high while ROI is negative.
Why is my ROAS different in Google Ads and in my shop?
Different attribution models and tracking gaps. Compare trends over time rather than one exact number.
