Worked example
With revenue of 5000 and ad spend of 1000, ROAS is 5000 / 1000 = 5x, and ROI is (5000 - 1000) / 1000 x 100 = 400%.
What this tool does not do / Limits
This tool only calculates from the numbers you enter. It is not financial advice and it does not predict future ad performance. It does not connect to any advertising account.
Frequently asked questions
What does a ROAS of 5x mean?
It means 5 units of revenue were entered for every 1 unit of ad spend entered. It says nothing about profit after other costs, which are not part of this calculation.
Why does ad spend have to be greater than zero?
ROAS divides by ad spend, and division by zero has no defined result, so a spend of zero or less cannot produce a ratio.
