When a mutual fund advertises "20% returns," do they mean last year? Over five years? Since inception? CAGR — Compound Annual Growth Rate — is the one number that makes investment comparisons honest. Here is everything you need to know.
CAGR is the rate at which an investment would have grown each year if it grew at a steady rate — as if compounding happened smoothly year over year. Real investments are volatile; CAGR smooths that volatility into a single, comparable annual growth number.
It answers the question: "If my investment grew at the same rate every year, what would that annual rate be?"
CAGR = (Ending Value ÷ Beginning Value)^(1 ÷ Number of Years) − 1
Expressed as a percentage by multiplying by 100.
You invested ₹1,00,000 in a mutual fund in 2021. In 2026 (5 years later) it is worth ₹2,10,000.
CAGR = (2,10,000 ÷ 1,00,000)^(1/5) − 1
= (2.10)^(0.2) − 1
= 1.1598 − 1
= 15.98% per year
| Fund | Invested | Value (5 yr) | CAGR |
|---|---|---|---|
| Fund A | ₹1,00,000 | ₹2,10,000 | 16.0% |
| Fund B | ₹1,00,000 | ₹1,95,000 | 14.3% |
| Fund C | ₹1,00,000 | ₹2,30,000 | 18.1% |
Fund C wins even though all three had the same starting amount. Without CAGR you would need to calculate each manually.
| Metric | What it shows | Best used for |
|---|---|---|
| Absolute Return | Total % gain over entire period | Quick glance; not time-adjusted |
| CAGR | Annual growth rate (lump sum) | Comparing lump sum investments |
| XIRR | Annual return for irregular cash flows | SIPs, multiple investments/withdrawals |
Important: CAGR only works for lump sum investments. If you invested through monthly SIPs, use XIRR instead — CAGR will overstate your actual returns.
| Asset Class | Typical 10-Year CAGR (India) |
|---|---|
| Fixed Deposit (FD) | 6–7% |
| PPF | 7–7.5% |
| Gold | 9–11% |
| Nifty 50 Index Fund | 12–14% |
| Large-Cap Mutual Fund | 13–16% |
| Mid-Cap Mutual Fund | 16–20% |
| Small-Cap Mutual Fund | 18–24% (high volatility) |
A CAGR beating inflation (currently ~5–6% in India) is the minimum bar. Beating FD rates (6–7%) means your money is genuinely growing in real terms.
You can reverse the CAGR formula to find out how much you need to invest to reach a goal.
Formula: Required Investment = Goal Amount ÷ (1 + CAGR)^Years
Example: You want ₹50 lakhs in 10 years. You expect a CAGR of 12%.
Required lump sum = 50,00,000 ÷ (1.12)^10 = 50,00,000 ÷ 3.1058 = ₹16.1 lakhs today
Not exactly. Annual return is the actual return in a specific year. CAGR is the smoothed average growth rate across multiple years. A fund can have -10% in year 1 and +40% in year 2, but still show a CAGR of around 13%.
Yes. If your ending value is less than your starting value, CAGR will be negative. This simply means the investment lost value over that period on an annualised basis.
Use: =(End_Value/Start_Value)^(1/Years)-1. Format the cell as a percentage.
