ROI Calculator computes net profit and return-on-investment percentage from an initial investment and final value, plus an annualized ROI that normalizes results to a per-year rate so a 6-month campaign and a 2-year purchase can be compared on equal footing instead of just raw percentages.
Enter the initial investment
What you put in ad spend, equipment cost, purchase price.
Enter the final value or return
What you got back or the current value.
Enter the time period
In months, to compute an annualized rate.
