CAGR Explained: What It Means, How to Calculate It, and Why It Matters
What is CAGR?
CAGR (Compounded Annual Growth Rate) is the rate at which an investment grows from its beginning value to its ending value over a specific period, assuming profits are reinvested every year.
It’s the single most useful metric for comparing investments — because it accounts for compounding and smooths out year-to-year volatility into a single, easy-to-compare annual percentage.
The CAGR Formula
CAGR = (End Value / Begin Value)^(1/Years) − 1
Example: You invested ₹1,00,000 in a mutual fund. After 7 years, it’s worth ₹2,50,000.
CAGR = (2,50,000 / 1,00,000)^(1/7) − 1
= (2.5)^(0.1429) − 1
= 1.1399 − 1
= 13.99% per year

CAGR vs Absolute Return vs XIRR
These three metrics confuse many investors. Here’s the difference:
| Metric | What it shows | Best used for |
|---|---|---|
| Absolute Return | Total % gain regardless of time | Comparing total gain only |
| CAGR | Annualised growth rate (lump sum) | Comparing one-time investments |
| XIRR | Annualised return for irregular cash flows | SIPs, multiple investments/withdrawals |
Example of why CAGR matters:
- Fund A: 50% return in 3 years (CAGR = 14.47%)
- Fund B: 100% return in 7 years (CAGR = 10.41%)
Fund A has a lower absolute return but a higher CAGR — it grew your money faster per year.
CAGR of Popular Asset Classes (Historical, India)
These are long-term historical averages — not guarantees:
| Asset Class | Approx. CAGR (20 years) |
|---|---|
| Nifty 50 | ~12% |
| Mid Cap Index | ~14–16% |
| Gold | ~11% |
| Real Estate (metro) | ~8–10% |
| FD (SBI) | ~6–7% |
| PPF | ~7–8% |
| Savings Account | ~3–4% |
Understanding CAGR Intuitively: The Rule of 72
The Rule of 72 is a quick mental math trick using CAGR:
Years to double = 72 ÷ CAGR
| CAGR | Years to double |
|---|---|
| 6% | 12 years |
| 8% | 9 years |
| 10% | 7.2 years |
| 12% | 6 years |
| 15% | 4.8 years |
A savings account at 3.5% doubles your money in 20.6 years. An equity fund at 12% doubles it in 6 years. This is why starting early matters so much.
Common CAGR Traps to Avoid
1. High CAGR Over Short Periods is Misleading
A fund showing 50% CAGR over 1 year just means it had a great year. One-year CAGR = one-year absolute return. Meaningful CAGR requires at least 5 years.
2. CAGR Hides Volatility
A fund delivering 12% CAGR over 10 years may have dropped 50% in year 3 and recovered. CAGR tells you the destination, not the journey. Check standard deviation or Sharpe ratio for volatility context.
3. CAGR vs XIRR for SIPs
Never use CAGR to evaluate a SIP return. Because you invest different amounts at different times, CAGR is meaningless. Always use XIRR for SIPs and recurring investments.
How Mutual Funds Report Returns
SEBI mandates that mutual funds report returns as:
- Absolute returns for tenures less than 1 year
- CAGR for tenures of 1, 3, and 5 years
This makes CAGR the standard benchmark for fund comparison in India. When you see “5-year return: 14.2%” on a fund fact sheet, that’s the 5-year CAGR.
Negative CAGR
CAGR can be negative if your investment lost value:
Example: ₹5 lakh invested in a stock. After 4 years: ₹3.8 lakh.
CAGR = (3.8/5)^(1/4) − 1 = (0.76)^(0.25) − 1 = −6.65%
A negative CAGR of 6.65% means you lost 6.65% of your value per year — worse than keeping cash under a mattress.
Conclusion
CAGR is your financial scoreboard metric. Once you understand it, you can compare any two investments — across asset classes, time periods, and amounts — on an equal footing. Use our CAGR Calculator to analyse your investments and project where they’ll go at current growth rates.
