How this roi calculator works

ROI is (ending value minus cost) divided by cost, shown as a percentage. It is a total return for the numbers you enter, not an annualized rate, and it does not time-weight cash flows.

Important: Review the assumptions shown under each input. Changing one assumption can materially change the result.

When to use this calculator

Get a simple profit or loss percentage on one completed cost and ending value.
Compare two finished deals without converting them to an annual rate.
Use the investment-return calculator instead if you need CAGR over a number of years.

Frequently asked questions

Is this annualized?

No. A 20% ROI over two years is still shown as 20%, not 10% per year.

Can ROI be negative?

Yes. If the ending value is below cost, the percentage is a loss.

Are fees and taxes included?

Only if you build them into the cost or ending value. The tool does not add them.
