What Is CAGR and How to Calculate It

Compound Annual Growth Rate (CAGR) is the rate at which an investment would have grown if it grew at a steady rate each year. It is the most widely used metric to compare investments across different time horizons because it smooths out year-to-year volatility and reflects the effect of compounding. SEBI mandates that mutual fund performance data in India be disclosed using CAGR for periods of one year and above.

CAGR Formula

CAGR = (Ending Value ÷ Beginning Value)^(1 ÷ Number of Years) − 1

The result is expressed as a percentage. A negative CAGR means the investment lost value over the period. CAGR differs from simple average return: if an investment gains 100% one year and loses 50% the next, the simple average is 25%, but the actual return is 0% (back to start) — which CAGR correctly captures.

Worked Example

You invested ₹1,00,000 in a mutual fund in 2017. In 2024 (7 years later), the value is ₹2,50,000.

This 14% CAGR means your investment would have had to grow at exactly 14% every single year to produce the same ending value. Use CAGR to compare a mutual fund delivering 14% CAGR over 7 years against a bank FD that offered 7% per year — the fund outperformed by 7 percentage points annually on a compounded basis.
