Meta Ads ROAS & Profit Calculator
Calculate your Meta Ads return on ad spend, then add your margin to see the real profit behind the ROAS — including profit on ad spend (POAS).
Your numbers
Total spent on the campaign or period.
Attributed revenue from that spend.
Add your margin to also see real profit, not just ROAS.
Enter your ad spend and revenue to calculate ROAS.
ROAS is not the same as profit
A high ROAS on a low-margin product can still lose money, while a modest ROAS on a high-margin product can be very profitable. This calculator shows ROAS on its own, then layers in your contribution margin so you can see the profit that actually reaches your account.
ROAS
ROAS = Revenue from ads ÷ Ad spend
Profit on ad spend (POAS)
POAS = Gross profit from ads ÷ Ad spend
Why add your margin
Without a margin, ROAS is just a revenue ratio. Adding your contribution margin turns it into profit after ad spend and a break-even ROAS you can benchmark every campaign against. Across a portfolio of accounts, spotting which ones sit below break-even is exactly the kind of check KARB automates.
