Formula
ROI = (Final − Invested) ÷ Invested × 100 CAGR = (Final ÷ Invested)^(1/years) − 1Worked example
10,000 grows to 15,000 in 3 years: ROI 50%, annualized about 14.47%.
Frequently asked questions
Why annualize?
A 50% return over 3 years is very different from 50% over 10 years — CAGR puts both on a yearly basis.
What about cash flows in between?
For uneven cash flows use IRR; this calculator assumes one deposit and one withdrawal.
