How to use the ROI Calculator
- Enter the amount invested and the final value.
- Optionally enter years held.
- Read ROI and annualized ROI.
How it works
ROI % = (Final value − Initial investment) ÷ Initial investment × 100. Annualized ROI = (Final ÷ Initial)^(1/years) − 1, which makes investments held for different periods comparable.
Worked example
Invest 200,000 and end with 290,000 after 3 years: ROI 45%, annualized ROI about 13.2%.
Good to know
ROI ignores risk and, unless annualized, the time it took to earn the return.
Include fees and taxes in the final value for a realistic figure.
Use annualized ROI to compare different time periods.
