ROI Calculator
Calculate your return on investment (ROI) and annualized ROI from an initial investment and its final value.
How ROI is calculated
ROI (%) = (Final Value − Initial Investment) ÷ Initial Investment × 100.
If you provide a duration in years, we also calculate the annualized ROI - the compound annual growth rate (CAGR) that would produce the same overall return, useful for comparing investments held for different periods.
Why annualized ROI matters
A 40% return over 5 years is very different from a 40% return in 1 year. Annualized ROI normalizes both so you can compare them fairly.
