ROI Calculator
Enter what you put in, what it's worth now, and how long you held it, to see both total ROI and the annualized return.
Overview
Total ROI on its own can be misleading when comparing investments held for different lengths of time — a 40% return over ten years is a very different outcome than the same 40% over one year. This calculator gives you both figures: the total percentage gain or loss, and the annualized rate that spreads that gain evenly across each year held, which is the number that actually makes different holding periods comparable.
Examples
10,000 grows to 14,000 over 3 years
Initial: 10000, Final: 14000, Years: 3
ROI: 40.00% Annualized Return: 11.87%
How It Works
- Enter your initial investment amount and its current or final value.
- Enter how many years you held the investment.
- See both total ROI and annualized return calculated instantly.
FAQ
No. The calculation runs entirely in your browser.
ROI is the total percentage gain or loss over the whole holding period. Annualized return spreads that same gain evenly across each year, so you can compare investments held for different lengths of time.
Leave years at 0 or blank — you'll still get the total ROI, just without an annualized figure.
No. This calculator compares a single initial amount to a single final amount — ongoing contributions, withdrawals, and fees aren't factored in.
