Question 1

What is Compound Annual Growth Rate (CAGR)?

Accepted Answer

Compound Annual Growth Rate (CAGR) represents the annualized constant rate of return required for an investment to grow from its beginning initial balance to its ending final balance over a specified number of years.

Question 2

How is CAGR calculated?

Accepted Answer

CAGR is calculated using the formula: CAGR = (Final Value / Initial Value)^(1 / Years) - 1. It geometric-averages annual returns over time, smoothing out market fluctuations.

Question 3

When should I use CAGR instead of Absolute Return?

Accepted Answer

Use CAGR whenever evaluating investments held for longer than one year. Absolute return ignores the time horizon, whereas CAGR annualizes growth to allow direct apples-to-apples comparisons.

Question 4

Can CAGR be negative?

Accepted Answer

Yes. If the final value of an investment is lower than its initial purchase price, the CAGR will be negative, reflecting an annualized loss.

Question 5

Can I use CAGR for SIP investments?

Accepted Answer

No. CAGR is designed exclusively for one-time lump sum investments. For recurring or periodic investments like SIPs with multiple cash flows, use XIRR (Extended Internal Rate of Return) instead.

Question 6

What is considered a good CAGR for equity mutual funds in India?

Accepted Answer

Historically, broad Indian equity indices (such as the Nifty 50 and BSE Sensex) and diversified equity mutual funds have delivered long-term CAGRs between 12% and 15% over 10+ year horizons.

Question 7

Does CAGR reflect actual year-by-year volatility?

Accepted Answer

No. CAGR provides an imaginary smoothed annual rate. It does not reveal whether the investment experienced sharp market drawdowns or sudden surges during intermediate years.

Question 8

How does inflation affect my CAGR?

Accepted Answer

CAGR measures nominal return. To determine your Real CAGR (purchasing power growth), subtract the average annual inflation rate from your nominal CAGR using the Fisher equation.

Question 9

Is CAGR the same as IRR?

Accepted Answer

For a single initial cash outflow followed by a single final cash inflow at maturity, CAGR and IRR are mathematically identical. For multiple cash flows at irregular intervals, IRR/XIRR must be used.

Question 10

What is the Rule of 72 in relation to CAGR?

Accepted Answer

The Rule of 72 is a quick estimation shortcut: dividing 72 by the CAGR gives the approximate number of years required for your investment capital to double (e.g. 72 / 12% CAGR ≈ 6 years).
