CAGR (Compound Annual Growth Rate) is the single most important metric for comparing investment returns. Unlike absolute returns that can mislead (50% over 5 years sounds good, but that's only 8.4% CAGR), CAGR tells you the steady annual rate at which an investment has grown โ apples to apples across all time periods and asset classes.
CAGR Formula
CAGR = (Final Value รท Initial Value)^(1 รท Years) โ 1
Example: Investment grew from โน1,00,000 to โน2,00,000 in 5 years. CAGR = (2,00,000รท1,00,000)^(1/5) โ 1 = 2^0.2 โ 1 = 1.1487 โ 1 = 14.87%

CAGR vs Absolute Return vs XIRR
- Absolute Return: Simple % gain. (FinalโInitial)/Initial. Good for short periods but misleading over long periods.
- CAGR: Annualized return assuming compounding. Best for lump sum investments held for a fixed period.
- XIRR: Internal rate of return for irregular cash flows (like SIP). More accurate than CAGR for monthly investments.
Rule of 72 โ Quick Mental Math
Divide 72 by the CAGR to find how many years it takes to double your money: At 12% CAGR โ 72รท12 = 6 years to double. At 7.1% PPF โ 72รท7.1 = ~10 years. At 20% mid-cap โ 72รท20 = 3.6 years.
