Frequently asked questions
How do I calculate ROI?
ROI = (gain − investment) ÷ investment × 100. An ROI of 50% means each $1 invested came back with $0.50 of profit.
What is annualized ROI?
It is ROI converted to one year, to compare investments of different lengths: (1 + ROI) raised to (12 ÷ months), minus 1.
What about ROAS?
ROAS is revenue divided by ad spend, without subtracting costs. The calculator shows both when you enter the revenue.
