- Enter the revenue it produced and your gross margin on that revenue.
- Add any running monthly cost that came with it, and the number of months.
The ROI formula
ROI = (gross profit produced − total cost) ÷ total cost × 100%. A 100% ROI means you doubled your money. The calculator uses gross profit, not revenue, so the result is what the spend really earned you.
Why use profit, not revenue?
$1,400 in sales on a 60% margin is $840 of profit. Measured on revenue, a $350 spend looks like a 300% return; measured on profit, it's 140%. Both are good, but only the second one is real.

FAQ
What's the difference between ROI and ROAS?
ROAS is revenue ÷ ad spend and ignores costs. ROI uses profit, so it tells you if the money actually came back.
