About the Return on Investment (ROI) Calculator
Return on investment (ROI) shows how much you gained relative to what you spent, as a percentage. Enter what you got back from the investment and what it cost; with ₹1,25,000 returned on ₹1,00,000 invested, ROI is 25%.
ROI is simple and works for almost any purchase, from a stock to a piece of equipment.
ROI formula
ROI = (Gain from investment − Investment cost) ÷ Investment cost × 100
Things to keep in mind
- ROI ignores time: 25% over one year is far better than 25% over ten.
- Include all costs — fees, taxes and maintenance — in the investment cost.
- Use CAGR when you need to compare returns over different periods.
