ROI Calculator – Return on Investment
The Return on Investment (ROI) Calculator is a financial tool designed to measure the profitability of an investment. It helps individuals and businesses evaluate the efficiency or potential return of a particular investment by comparing the gain from the investment to its cost. This tool is useful for assessing past investment performance or forecasting future gains.
ROI Formula & Explanation

Where:
- Net Profit = Final Value − Initial Investment
- Investment Cost = Initial Investment
🧠 What ROI Tells You
- It gives a quick, overall snapshot of how much you gained or lost from your investment.
- It doesn’t account for time duration.
📊 Example (ROI):
Aman had made an investment of ₹10,000 3 years ago and today after 3 years the final value of investment is ₹15,000 so the Net Profit is ₹5,000 and Return On Investment (ROI) as 50%
CAGR Formula & Explanation

Where:
- n = Number of years
- Initial Value = Starting investment
- Final Value = Ending value of investment
🧠 What CAGR Tells You
- It gives the annualized growth rate — how much your investment has grown per year on average.
- Unlike ROI, CAGR considers the time factor and shows compound growth.
📊 Example (CAGR):
So, continuing the above example Aman had made an investment of ₹10,000 3 years ago and today after 3 years the final value of investment is ₹15,000 so the Net Profit is ₹5,000 and Return On Investment (ROI) as 50% and CAGR comes out to be 14.47%
