What is CAGR (Compound Annual Growth Rate)?
CAGR is the constant annual growth rate that takes an investment from its beginning value to its ending value over a specified period.
Compound Annual Growth Rate (CAGR) represents the mean annual growth rate of an investment over a specified time period longer than one year. It tells you the rate at which your investment would have grown if it had grown at a steady rate each year.
Unlike simple averages, CAGR smooths out volatility to give you a single growth rate. If your stock went up 50% one year and down 20% the next, CAGR tells you the equivalent steady annual rate that would give the same final result.
CAGR is widely used to compare the historical performance of investments, evaluate portfolio returns, and set realistic expectations for future growth based on past performance.
- Initial Investment: ₹1,00,000
- After 3 years: ₹1,33,100
- Absolute Return: 33.1%
- CAGR: 10% per year
- This means: If your investment grew
- exactly 10% every year for 3 years,
- you would get ₹1,33,100

CAGR ≠ Average Return
CAGR is the smoothed annual growth rate that accounts for compounding — the single best number to compare investment performance.
CAGR Formula: How to Calculate
CAGR = (Ending Value / Beginning Value)^(1/n) - 1, where n is the number of years.
The CAGR formula derives the constant annual rate needed to grow the beginning value to the ending value. It uses the nth root (where n = years) to "reverse" the compounding effect.
Formula: CAGR = (EV/BV)^(1/n) - 1, where EV is ending value, BV is beginning value, and n is number of years. The result is expressed as a percentage.
This formula works for any time period. For periods less than a year, n becomes a fraction (e.g., 6 months = 0.5 years). For monthly calculation, divide by 12.
- Beginning Value (BV): ₹50,000
- Ending Value (EV): ₹80,000
- Time Period (n): 5 years
- Step 1: EV/BV = 80,000/50,000 = 1.6
- Step 2: (1.6)^(1/5) = 1.6^0.2 = 1.0986
- Step 3: 1.0986 - 1 = 0.0986
- Step 4: 0.0986 × 100 = 9.86%
- CAGR = 9.86% per year
Quick mental math
CAGR = (Ending Value / Beginning Value)^(1/years) - 1. This formula reverse-engineers the steady growth rate.
CAGR vs Absolute Return: Key Differences
Absolute return shows total gain; CAGR shows annualized rate. Always use CAGR when comparing investments of different durations.
Absolute return is simply (Ending Value - Beginning Value) / Beginning Value × 100. It tells you the total percentage gain but ignores time. A 50% return in 2 years is very different from 50% in 10 years.
CAGR normalizes returns to an annual basis. This makes it possible to compare a 5-year investment with a 3-year investment fairly. Higher CAGR = better annualized performance.
When comparing investments, always ask: "What was the CAGR?" rather than "What was the total return?" This prevents being misled by long-duration, low-performing investments.
- Investment A: ₹1L → ₹2L in 5 years
- Absolute Return: 100%
- CAGR: 14.87%
- Investment B: ₹1L → ₹2L in 10 years
- Absolute Return: 100%
- CAGR: 7.18%
- Same total return, but Investment A
- performed 2× better annually!

Absolute return ignores time; CAGR accounts for it. Use CAGR to compare investments with different holding periods.
Interpreting CAGR: What's Good, What's Bad?
A "good" CAGR depends on asset class, risk, and market conditions. Compare against benchmarks, not arbitrary numbers.
There's no universal "good" CAGR. For equity investments, 12-15% CAGR is considered excellent over long periods. For fixed income, 7-8% may be good. Real estate often targets 8-12%.
Always compare CAGR against relevant benchmarks. If Nifty 50 delivered 11% CAGR over 10 years, your equity fund should ideally beat that. For debt funds, compare against fixed deposit rates.
Higher CAGR usually means higher risk. A stock with 25% CAGR might have had years of -30% and +80%. Consider both CAGR and volatility (standard deviation) when evaluating investments.
Past CAGR ≠ Future Returns
| Asset Class | Expected CAGR Range | Risk Level |
|---|---|---|
| Fixed Deposits | 6-8% | Very Low |
| Debt Mutual Funds | 7-9% | Low |
| Balanced/Hybrid Funds | 9-12% | Medium |
| Large Cap Equity | 10-14% | Medium-High |
| Mid/Small Cap Equity | 12-18% | High |
| Individual Stocks | Varies widely | Very High |
Judge CAGR relative to the asset class and benchmark. Higher CAGR often means higher risk — evaluate both.
Limitations of CAGR: What It Doesn't Tell You
CAGR hides volatility, ignores cash flows, and can be misleading for short periods or irregular investments.
CAGR assumes smooth growth, but real investments are volatile. Two funds with 12% CAGR might have vastly different journeys — one steady, one with wild swings. CAGR doesn't capture this difference.
CAGR only works for lump sum investments. If you invested via SIP (regular monthly amounts), CAGR doesn't apply — you need XIRR (Extended Internal Rate of Return) for accurate measurement.
For short periods (under 3 years), CAGR can be misleading. A stock that dropped 50% in year 1 and recovered 120% in year 2 shows 10% CAGR — hiding the gut-wrenching volatility.
- Fund A (Steady): +10%, +10%, +10%, +10%
- Fund B (Volatile): +40%, -20%, +30%, -5%
- Both have similar 4-year CAGR (~10%)
- But Fund B had:
- - Maximum drawdown: -20%
- - Emotional stress: High
- - Redemption risk: Higher
For SIP investments, use XIRR
CAGR hides volatility and only works for lump sum. Use it with standard deviation and for single investments only.
Reverse CAGR: Calculate Future Value
If you know the CAGR, you can calculate how much your investment will grow to, or what CAGR you need to reach a goal.
Reverse CAGR calculation helps in goal planning. If you want ₹1 crore in 15 years and have ₹10 lakh today, what CAGR do you need? Applying the formula: (100/10)^(1/15) - 1 = 16.6%.
You can also calculate the future value given a CAGR: FV = PV × (1 + CAGR)^n. If you invest ₹5 lakh at 12% CAGR for 10 years: 5,00,000 × (1.12)^10 = ₹15.53 lakh.
This is powerful for retirement planning, children's education goals, or any long-term financial target. It tells you if your expected returns are realistic for your goals.
- Goal: ₹50 lakh for child's education
- Current savings: ₹10 lakh
- Time available: 12 years
- Required CAGR = (50/10)^(1/12) - 1
- = 5^0.0833 - 1
- = 1.142 - 1
- = 14.2%
- You need 14.2% CAGR to reach your goal.
- Equity funds may achieve this; FDs won't.

When to Use CAGR: Practical Applications
Use CAGR for comparing funds, tracking portfolio performance, evaluating business growth, and setting investment expectations.
Comparing mutual funds: When evaluating two funds over their 5-year or 10-year history, CAGR provides a fair comparison. The fund with higher CAGR (adjusted for risk) typically performed better.
Portfolio review: Calculate your overall portfolio CAGR annually. If your diversified portfolio delivered 11% CAGR over 5 years, compare it against a benchmark like Nifty 50 to evaluate your investment decisions.
Business valuation: CAGR is used to analyze revenue or profit growth. A company with 20% revenue CAGR over 5 years is growing faster than one with 10% CAGR — useful for stock picking.

| Scenario | Use CAGR? | Alternative |
|---|---|---|
| Lump sum investment | Yes | — |
| SIP/recurring investment | No | XIRR |
| Comparing funds (same period) | Yes | — |
| Short-term (< 1 year) | No | Absolute return |
| With dividends/cash flows | No | XIRR |
| Business revenue growth | Yes | — |
CAGR is best for lump sum comparisons over 3+ years. For SIPs or cash flow investments, use XIRR instead.
Frequently Asked Questions
What is a good CAGR for investments?
▾
What is a good CAGR for investments?
▾It depends on asset class. For equity, 12-15% CAGR is excellent long-term. For debt, 7-8% is good. Always compare against benchmarks relevant to your investment type.
How is CAGR different from average return?
▾
How is CAGR different from average return?
▾Average return is the arithmetic mean of yearly returns. CAGR is the geometric mean that accounts for compounding. CAGR gives a more accurate picture of actual growth.
Can CAGR be negative?
▾
Can CAGR be negative?
▾Yes, if your ending value is less than beginning value, CAGR will be negative. This indicates your investment lost value over the period.
Is CAGR same as compound interest?
▾
Is CAGR same as compound interest?
▾No. Compound interest is the actual interest earned. CAGR is a measurement tool — it calculates what the compound interest rate would have been if growth was steady.
Why is CAGR better than absolute return?
▾
Why is CAGR better than absolute return?
▾Absolute return doesn't account for time. A 100% return in 5 years (14.87% CAGR) is much better than 100% in 10 years (7.18% CAGR). CAGR makes this comparison possible.
Can I use CAGR for SIP investments?
▾
Can I use CAGR for SIP investments?
▾No, CAGR is for lump sum only. For SIP or any investment with multiple cash flows, use XIRR (Extended Internal Rate of Return) for accurate annualized returns.
How do I calculate CAGR in Excel?
▾
How do I calculate CAGR in Excel?
▾Use: =(Ending_Value/Beginning_Value)^(1/Years)-1. Format as percentage. Or use the RATE function: =RATE(Years,0,-Beginning_Value,Ending_Value).
What is the Rule of 72?
▾
What is the Rule of 72?
▾Divide 72 by CAGR to estimate doubling time. At 12% CAGR, money doubles in ~6 years (72/12). At 8% CAGR, it takes ~9 years (72/8).
Does CAGR include dividends?
▾
Does CAGR include dividends?
▾Only if you include dividend reinvestment in the ending value. For accurate total return CAGR, use total value including reinvested dividends, not just price appreciation.
Is higher CAGR always better?
▾
Is higher CAGR always better?
▾Not always. Higher CAGR often comes with higher risk/volatility. Consider risk-adjusted returns (Sharpe Ratio) along with CAGR for a complete picture.
