What is Compound Annual Growth Rate (CAGR)?
Compound Annual Growth Rate (CAGR) represents the constant annual rate at which an investment would grow if it grew at a steady compounded rate every year over a specific time horizon.
Unlike absolute returns (which just tell you the total percentage gained), CAGR accounts for the Time Value of Money. It smooths out the volatility of an investment and returns a single annualized percentage rate, allowing for direct comparison across different asset classes.
🎯 Investment Goal: To accurately compare the performance of highly volatile assets (like stocks or real estate) against fixed-return assets (like FDs).
⚠️ Common Fear: “Did my real estate investment actually beat the market?” Many people boast about buying land for ₹10 Lakhs and selling it for ₹30 Lakhs (a 200% absolute return). But if it took 15 years to do that, the CAGR is actually only ~7.6%, which is roughly the same as a risk-free Fixed Deposit!
💡 The Decision: Never use absolute returns to make investment decisions over multi-year periods. Always convert your total returns into a CAGR metric so you can objectively compare it against benchmark index funds.
CAGR Formula
The CAGR rate is solved using the following geometric equation:
Compound Annual Growth Rate
Example Calculation
Suppose you invested ₹1,00,000 in a mutual fund, and its value grew to ₹1,50,000 over a period of 3 years.
- Initial Principal: ₹1,00,000
- Final Value: ₹1,50,000
- Absolute Return: 50%
- CAGR: (150000 / 100000)^(1/3) - 1 = 14.47%
