About the ROI Calculator

Measure how well an investment performed: total return as a percentage, the gain or loss, and — if you enter the period — the compound annual growth rate so you can compare investments held for different lengths of time.

ROI Calculator formula

ROI = (return − cost) ÷ cost × 100
CAGR = (return ÷ cost)^(1 ÷ years) − 1

Example

$10,000 that becomes $14,500 in 3 years is a 45% ROI, or 13.2% a year.

Frequently asked questions

Why use annualised return?

A 45% return over 3 years and a 45% return over 10 years are very different. CAGR puts them on the same yearly basis.
