Enter a cost basis and final value — plus an optional holding period — to calculate ROI and, if applicable, the annualized return.
How to Use the ROI Calculator
Cost basis and final value are the two required fields; check the years box to also see the return annualized, which is the fairer number when comparing holding periods of different lengths.
Return on investment in its plainest form: what you got back, measured against what you put in, expressed as a percentage. It's the most-quoted investment metric precisely because it's this simple.
ROI = (Final Value − Cost) ÷ CostThat simplicity is also its limitation — a 50% ROI over one month and a 50% ROI over ten years are wildly different outcomes, and plain ROI treats them identically. Turn on the annualized option and this calculator spreads the same return across the number of years entered, which is the fairer number for comparing investments held over different time periods.
