How it works

ROI shows total profit as a percentage of what you put in. Annualized return spreads that over the holding period, so you can compare investments held for different lengths of time.

Formula

ROI = (Returned − Invested) ÷ Invested × 100
Annualized = (Returned ÷ Invested)^(1/years) − 1

Example

$10,000 growing to $14,500 over 3 years: ROI = 45%, annualized ≈ 13.19% per year.

Frequently asked questions

Does ROI include fees and taxes?

Only if you include them. Subtract fees from the amount returned for a more realistic figure.
