Measure your performance with an ROI calculator
Determining the actual profitability of your assets is the cornerstone of smart wealth management. An online Return on Investment (ROI) calculator eliminates the guesswork, helping you evaluate absolute gains and compound annual growth rates (CAGR) instantly across any holding period.
Using our free online ROI calculator simplifies these return calculations. If you need to calculate investment return rate for any portfolio (mutual funds, stocks, properties), simply enter your initial investment, final value, and holding tenure above.
Why use an online ROI calculator?
Standardise asset comparison
Compare real estate gains directly against stock market or gold returns on an equal footing.
Calculate true compound growth
Unveil the CAGR of your investment to understand how the asset performed on a yearly basis.
Track net gains and losses
Establish exact monetary changes between your purchase price and current valuation.
Immediate mathematical output
Save time and bypass manual fractional exponent calculations or spreadsheets.
How to use this ROI calculator
You only need to enter your initial investment amount, the final value of the asset, and the holding period in years. The calculator immediately processes the variables, updating the absolute ROI, the CAGR, and the total monetary gain on the spot.
The mathematical formula for ROI and CAGR
This calculator measures two crucial metrics: absolute ROI to show you raw growth, and CAGR to account for the impact of time:
Understanding the variables helps you see how the math works:
| Variable | Meaning | Details |
|---|---|---|
| Initial Value | Purchase Price | The total capital you initially spent to acquire the asset. |
| Final Value | Current/Sale Value | The market value of the asset today, or the amount received upon selling. |
| Years | Holding Period | The duration of time (can include decimals) you owned the investment. |
Comparing returns across different milestones
Holding an investment over different periods changes its annualized growth rate dramatically. Below is a comparison showing the CAGR and absolute return for an initial capital of ₹10 lakh growing to different final values over a 5-year tenure:
| Final value | Investment period | Absolute ROI | Annualised CAGR |
|---|---|---|---|
| ₹15,00,000 | 5 Years | 50.00% | 8.45% p.a. |
| ₹20,00,000 | 5 Years | 100.00% | 14.87% p.a. |
| ₹25,00,000 | 5 Years | 150.00% | 20.11% p.a. |

Worked example: Comparing investment asset returns
Consider why focusing solely on raw profit (Absolute ROI) can be misleading. Below is a comparison of investing the exact same initial capital of Rs. 10 Lakh across three different asset classes held over different tenures:
| Asset class | Initial capital | Final value | Holding tenure | Absolute ROI | Annualised CAGR |
|---|---|---|---|---|---|
| Real Estate | Rs. 10,00,000 | Rs. 20,00,000 | 10 Years | 100.00% | 7.18% p.a. |
| Index Fund | Rs. 10,00,000 | Rs. 15,00,000 | 4 Years | 50.00% | 10.67% p.a. |
| Equity Stocks | Rs. 10,00,000 | Rs. 25,00,000 | 5 Years | 150.00% | 20.11% p.a. |
The real estate investment doubles the money (100% absolute return) but does so across a full decade, bringing the compound rate down to 7.18% annually. The index fund generates a lower absolute ROI of 50%, yet it does so in only 4 years, resulting in a higher annual velocity of 10.67%. The equity stocks achieve the highest combination, scoring a massive 150% absolute ROI over a moderate 5-year tenure to yield a compound growth rate (CAGR) of 20.11%.
Important note
This calculator provides gross ROI and CAGR figures before any taxes or fees. Keep in mind that capital gains taxes and inflation will reduce the actual purchasing power of your returns.
