ROI Calculator

What is a ROI?

ROI, or Return on Investment, is a performance metric used to evaluate the efficiency or profitability of an investment relative to its cost. It is one of the most widely used financial ratios in business, investing, and personal finance. A positive ROI means you made more than you invested. A negative ROI means you lost money. The annualized ROI goes further by accounting for how long you held the investment, enabling fair comparisons between short-term and long-term opportunities.

How to Use This Calculator

Enter your initial investment amount — the total cost including any fees or purchase price. Enter the final value — what the investment is worth now, or what you received when you sold it. Enter the holding period in years so the calculator can compute the annualized return. Click Calculate to see your total ROI percentage, net gain or loss in rupees, and the annualized return rate so you can compare it against other investments fairly.

💡 Pro Tips

• ✓Always calculate annualized ROI when comparing investments held for different lengths of time.
• ✓ROI does not account for risk — a 30% ROI from a stable asset is very different from a 30% ROI from a volatile one.
• ✓Include all costs in your initial investment — brokerage fees, taxes, maintenance, and setup costs all reduce real ROI.
• ✓Compare your ROI against inflation — if inflation is 12% and your ROI is 10%, your real return is actually negative.
• ✓Use ROI alongside other metrics like payback period and NPV for a complete investment picture.
