ROI Calculator
Calculate ROI, net profit, return multiple and annualized ROI for a selected period.
About this tool
Measure whether an investment produced a profit or loss after including both the initial amount and additional costs. The result includes standard ROI, net profit and the return multiple.
Compare investments with different durations
Enter the duration in months to estimate annualized ROI. Annualization makes periods easier to compare, but it is a mathematical projection and does not guarantee a future return.
Use complete cost data
Include fees, implementation and other directly attributable expenses. Omitting costs can make ROI look better than the actual result.
How to use
Enter the initial investment, final value or total return, additional costs and duration in months. Calculate and review both ROI and net profit.
