What is CAGR?
CAGR is the smooth annualised rate at which a single lump-sum investment would have grown if it had compounded at a constant pace from start to end. It strips out the year-to-year volatility and gives you one clean number you can compare across mutual funds, stocks, gold, real estate, or an entire asset class. When a fund factsheet says "5-year CAGR 14.2%", that is the figure it means.
The formula is (Final Value / Initial Value)^(1 / Years) − 1. Turn ₹1,00,000 into ₹2,00,000 over 7 years and the CAGR is (2)^(1/7) − 1 ≈ 10.4%. Note that CAGR only works for a single inflow and a single outflow — it cannot handle SIPs, top-ups, or partial withdrawals. For those cashflow-stream situations, XIRR is the correct metric.
CAGR is not a guarantee: a 12% CAGR over a decade can hide a −40% year and a +60% year. Regulators in India require mutual funds to disclose CAGR only for periods of one year or longer, and to use absolute returns for shorter periods.
