About Investment ROI Calculator

The Investment ROI Calculator measures how an investment performed. From the initial investment and its final value it computes the return on investment percentage, the net profit or loss and the total return multiple. Add the holding period in years to also get the annualized return.

ROI = (final value − initial investment) ÷ initial investment, expressed as a percentage. The annualized return converts the total gain into an equivalent constant yearly rate — (final ÷ initial)^(1/years) − 1 — assuming the gain compounded evenly, which makes investments held for different lengths comparable.

Use it to evaluate a stock sale, a property flip, a business project or any before-and-after pair of numbers. Fees, taxes and additional contributions are not included, so use net figures for accuracy. Free and instant in your browser.

  3. Optionally enter the holding period in years to unlock the annualized return.

Frequently asked questions

ROI = (final value − initial investment) ÷ initial investment × 100. Buying at $10,000 and selling at $13,500 gives (13,500 − 10,000) ÷ 10,000 = 35% ROI and a $3,500 net profit.

It converts a total return into an equivalent constant yearly rate: (final ÷ initial)^(1/years) − 1. A 35% gain over 5 years annualizes to about 6.2% per year — the fair way to compare investments held for different periods.

Final value divided by initial investment. A multiple of 2.0× means the money doubled (100% ROI); 1.0× is break-even; below 1.0× is a loss. Venture investors commonly quote returns this way.

Broad stock indexes have historically averaged roughly 7–10% per year before inflation over long periods. Anything consistently above that involves extra risk; treat double-digit promises with skepticism.

No — it compares two values only, and results are estimates rather than financial advice. Use after-fee, after-tax figures, and note that money added along the way would need a money-weighted return method instead.
