ROAS calculator
ROAS (return on ad spend) shows how much revenue every advertising euro brings in. Enter your numbers — we work out immediately whether your campaign pays off.
Add your margin and we also show the ROAS at which you actually start making a profit.
Your ROAS—Please enter your ad spend and revenue.
How to read the result
ROAS = revenue ÷ ad spend. A ROAS of 4 means: every euro spent brings in €4 of revenue.
One caveat: revenue is not profit. Whether a campaign pays off depends on your margin — at a 25 % margin you need a ROAS of at least 4 just to cover the ad spend (break-even ROAS = 100 ÷ margin).
