How This Investment Return (ROI) Calculator Works
This calculator helps you measure how much profit or loss you made on an investment. It uses a simple and widely accepted ROI formula that compares your final value with your initial investment amount.
The main formula used is: ROI = (Final Value − Initial Investment) ÷ Initial Investment × 100. The tool also shows the gain in absolute currency terms and the investment multiple, which tells you how many times your money has grown.
If you enter the holding period in years, the calculator also provides an approximate annual return. All calculations happen instantly in your browser, and no data is stored or sent anywhere.
