About this tool
This ROI calculator turns an initial investment and a final value into net profit, return on investment in percent and the investment multiple. Add a duration in years to also see the annualized return.
How to use it
- Enter the initial investment and the final value.
- Optionally enter how many years you held the investment.
- Read net profit, ROI %, the multiple and, with a duration, the annualized return.
Good to know
- ROI = (final value − initial investment) ÷ initial investment × 100.
- Annualized return = (final value ÷ initial investment)^(1 ÷ years) − 1, also known as CAGR.
- Example: 5,000 growing to 7,500 is a 50% ROI and a 1.5x multiple; over 2 years that is about 22.5% per year.
- The multiple is simply final value divided by initial investment.

Frequently asked questions
What is a good ROI?
It depends on the risk and the time involved. ROI alone ignores time, so compare investments by annualized return when their durations differ.
What is the difference between ROI and annualized return?
ROI is the total gain over the whole period. Annualized return spreads that gain evenly across each year, which makes investments of different lengths comparable.
Can ROI be negative?
Yes. If the final value is lower than what you invested, net profit and ROI are negative, meaning you lost money.
Does the calculation include fees and taxes?
Only if you include them in the numbers you enter. Subtract costs from the final value, or add them to the initial investment, for a net figure.
