How to use this calculator
Calculate ROI, solve proceeds or cost for a target ROI, and optionally compare annualized return using years or actual calendar dates. Proceeds means all money received, not net gain.
- Enter find, total investment cost, total proceeds and review the remaining options.
- Select Calculate or change a value to update the result. Read the result label and units before copying.
- Use Reset to restore the worked starting values.
Formula and method
Annualization treats proceeds as ending wealth and uses elapsed days/365.2425 for dates. It does not account for timed intermediate cash flows or risk.
Worked example
Cost 1,000 and proceeds 1,250 give a net return of 250 and ROI 25%.
Questions about roi calculator
Do I enter net gain or total proceeds?
In the standard mode enter total proceeds, not net gain. Cost 1,000 and proceeds 1,250 give net return 250 and total ROI 25%. An optional holding period adds an annualized result; timed intermediate cash flows and investment risk are not captured by simple ROI.
What assumptions should I check?
Annualization treats proceeds as ending wealth and uses elapsed days/365.2425 for dates. It does not account for timed intermediate cash flows or risk.
