What is ROI and how is it calculated?
Return on Investment (ROI) measures the profitability of an investment relative to its cost. The basic formula is: ROI = (Final Value − Cost) / Cost × 100. It tells you what percentage of your original investment you gained (or lost). A positive ROI means you made money; a negative ROI means you lost.
However, raw ROI ignores time — a 50% return over 10 years is very different from a 50% return over 2 years. This is why annualised ROI (also called CAGR when compounding is assumed) is more useful for comparing investments held for different periods. This calculator shows both so you can see the full picture.
In India, ROI is used across equity, real estate, fixed deposits, gold, and business investments. When comparing options, always use annualised ROI to account for the time value of money. A real estate investment with 60% ROI over 8 years (7.5% annualised) might underperform an equity SIP with 12% annualised returns.
