CAGR is the great equaliser of investments: it converts any lumpy, irregular growth into a single smooth yearly rate, so you can compare a stock, a mutual fund and a property on equal footing.
Example: ₹1 lakh becoming ₹2 lakh in 5 years is a 14.87% CAGR — but also 'just' a 100% total gain. Both numbers describe the same journey; CAGR just makes it comparable.
Frequently asked questions
CAGR vs XIRR — what's the difference?
CAGR handles one investment and one redemption. XIRR handles multiple cash flows at irregular dates (like SIPs). For SIP returns, XIRR is the right tool; for a single lumpsum, CAGR.
Why is my fund's CAGR different from my actual return?
Published fund CAGR assumes a lumpsum invested on day one. If you invested via SIP at different NAVs, your personal return (XIRR) will differ — often lower in rising markets.
Can CAGR be negative?
Yes — if the end value is below the start value, CAGR goes negative, showing the annualised rate of loss.
What is the rule of 72?
Divide 72 by the CAGR to estimate doubling time: 72 ÷ 14.87 ≈ 4.8 years. A handy mental shortcut this calculator shows automatically.
