CAGR (Compound Annual Growth Rate)
CAGR (Compound Annual Growth Rate) is the steady yearly rate at which an investment would have grown from its starting value to its ending value, assuming all gains were reinvested every year.
What Is CAGR (Compound Annual Growth Rate)?
CAGR (Compound Annual Growth Rate) tells you the average rate at which an investment grew each year, after accounting for compounding. It answers a simple question: "If my money had grown at one fixed rate every year, what would that rate be?"
Real investments rarely grow smoothly. A fund may rise 25% one year, fall 8% the next and gain 15% after that. CAGR smooths these ups and downs into a single yearly figure, so you can compare investments held for different lengths of time.
You will see CAGR in mutual fund factsheets, fund comparison websites, company annual reports and calculators. Understanding it helps you read performance numbers correctly and avoid being misled by large-looking total returns.
How Does CAGR Work?
CAGR compares only two points: the value at the start and the value at the end. The formula is:
CAGR = (Ending Value ÷ Beginning Value)^(1 ÷ Number of Years) − 1
Step by step:
- Divide the ending value by the beginning value. This gives the growth multiple.
- Raise this multiple to the power of 1 divided by the number of years. This "spreads" the growth evenly across the years.
- Subtract 1 and multiply by 100 to express it as a percentage.
For periods that are not whole years, the number of years is usually calculated as the number of days divided by 365.
Practical Example
Illustrative example 1: lump sum growth
Priya invests ₹1,00,000 in a mutual fund on 1 April 2021. On 1 April 2026, exactly 5 years later, her investment is worth ₹1,61,051.
- Growth multiple = ₹1,61,051 ÷ ₹1,00,000 = 1.61051
- 1 ÷ 5 years = 0.2, so 1.61051^0.2 = 1.10
- CAGR = 1.10 − 1 = 0.10, or 10% per year
Her absolute return is 61.05% (₹61,051 gain on ₹1,00,000). If she simply divided 61.05% by 5, she would get 12.21% per year, which overstates her yearly growth because it ignores compounding.
Illustrative example 2: why simple averages mislead
Suppose ₹1,00,000 rises 50% in Year 1 (to ₹1,50,000) and then falls 50% in Year 2 (to ₹75,000).
- Simple average return = (50% − 50%) ÷ 2 = 0%
- CAGR = (₹75,000 ÷ ₹1,00,000)^(1/2) − 1 = 0.866 − 1 = −13.4% per year
The investor actually lost ₹25,000, and CAGR reflects this. The simple average does not.
Why Is CAGR Important?
- Fair comparison across time periods: A 40% gain over 2 years and a 60% gain over 5 years cannot be compared directly. CAGR converts both to yearly rates (about 18.3% and 9.86% respectively).
- Realistic goal planning: Long-term plans for financial goals such as retirement or a child's education are built on assumed yearly growth rates. CAGR is the natural way to express these.
- Checking against inflation: Comparing CAGR with the inflation rate gives a rough idea of your real rate of return.
- Reading fund performance: Fund factsheets typically show returns for periods longer than one year on a compounded annualised basis, which is the same idea as CAGR.
Key Features of CAGR
- Uses only two data points: start value and end value. What happened in between does not affect the result.
- Includes compounding: it assumes gains are reinvested, unlike simple interest calculations (see Simple Interest vs Compound Interest).
- Expressed as a yearly percentage: this makes it comparable with FD rates, inflation and other annual figures.
- Backward-looking: CAGR describes past growth; it does not predict future returns.
Benefits and Limitations
| Benefits | Limitations |
|---|---|
| Simple, single number that is easy to compare | Hides the ups and downs (volatility) along the way |
| Accounts for compounding correctly | Unsuitable for SIPs or multiple cash flows |
| Works for any asset: funds, stocks, property, revenue | Highly sensitive to the start and end dates chosen |
| Useful for long-term goal planning | Says nothing about the risk taken to earn the return |
A common pitfall is date sensitivity. A fund's 5-year CAGR measured from a market peak can look very different from one measured from a market low, even if the fund is the same.
Comparison With Related Concepts
| Concept | Meaning | Key difference from CAGR | Practical implication |
|---|---|---|---|
| Absolute Return | Total percentage gain or loss over the whole period | Ignores how long the money was invested | Fine for periods under a year; misleading over longer periods |
| Annualised Return | Return expressed on a yearly basis | CAGR is one form of annualised return (compounded) | Check whether a quoted "annual" figure is compounded or simple |
| XIRR | Annualised return for multiple cash flows on different dates | Handles SIPs, top-ups and withdrawals | Use XIRR to judge your own SIP portfolio |
| Average annual return | Simple average of yearly returns | Ignores compounding; often higher than CAGR | Do not treat it as your actual yearly growth |
How Does CAGR Apply to Mutual Fund Investors?
- Scheme comparison: When comparing two schemes in the same category, look at their 3-year, 5-year and 10-year CAGR side by side, and against the benchmark over the same periods.
- Lump sum evaluation: If you made a one-time lump sum investment, CAGR (based on purchase NAV and current NAV) shows your yearly growth rate.
- Point-to-point vs rolling returns: A single CAGR figure is "point-to-point". Rolling returns, which calculate CAGR over many overlapping periods, give a better sense of consistency.
- Calculators: AMFI's investor education platform offers lump sum calculators that project values at an assumed growth rate (Mutual Funds Sahi Hai calculators). These are illustrations, not promises.
Common Mistakes and Misconceptions
- "CAGR means the fund grew by that much every year." In reality, yearly returns vary widely; CAGR is a smoothed figure. Expecting steady yearly growth can lead to panic when a bad year arrives.
- "I can use CAGR for my SIP returns." CAGR assumes one investment at the start. SIP money is invested gradually, so CAGR will misstate your return. Use XIRR instead.
- "Higher CAGR always means a better fund." CAGR ignores risk. A fund with slightly lower CAGR but much lower volatility may suit you better. Look at risk-adjusted return as well.
- "Past CAGR will continue." CAGR is historical. Future returns depend on markets, valuations and the fund's strategy.
- "Dividing total return by years gives CAGR." That gives a simple average, which overstates growth over multi-year periods, as Example 1 shows.
Important Terms to Know
- Absolute Return: total percentage change in value, without adjusting for time.
- Annualised Return: any return converted to a yearly rate.
- XIRR: annualised return for investments with multiple dated cash flows.
- Time Value of Money: the idea that money today is worth more than the same amount in the future.
- Real Rate of Return: return after adjusting for inflation.
- Volatility: how much returns fluctuate around their average.
- Benchmark: a reference index used to judge a fund's performance.
Key Takeaways
- CAGR is the smoothed yearly growth rate between a start value and an end value, including compounding.
- Formula: (End ÷ Start)^(1 ÷ Years) − 1.
- It is ideal for lump sum investments and comparing performance across different time periods.
- It hides volatility, ignores risk and does not work for SIPs; use XIRR for multiple cash flows.
- Past CAGR describes history, not future returns.

Frequently Asked Questions
What is a good CAGR for a mutual fund?
There is no universal "good" number. A reasonable CAGR depends on the asset class, the period and market conditions. Equity funds are usually compared with their benchmark index and category peers over the same period, while debt funds are compared with their own benchmarks. A CAGR is meaningful only in context, never in isolation.
Can CAGR be negative?
Yes. If the ending value is lower than the starting value, CAGR is negative. For example, ₹1,00,000 falling to ₹81,000 over two years gives a CAGR of −10% per year, since 0.81 raised to the power 0.5 equals 0.90.
How do I calculate CAGR in Excel or Google Sheets?
Use the formula =(End/Start)^(1/Years)−1. For example, =(161051/100000)^(1/5)−1 returns 0.10, or 10%. The RRI function, =RRI(years, start, end), gives the same result.
Is CAGR the same as annualised return?
CAGR is a type of annualised return that assumes compounding. Some sources use "annualised return" loosely, so check whether a figure is compounded. For periods longer than a year, the compounded figure (CAGR) is the standard measure.
Why does my fund's CAGR change every day?
CAGR is calculated using the latest NAV and the NAV on the start date. As the NAV changes daily, and as the start date moves forward for "trailing" periods like 3 or 5 years, the CAGR figure changes too.
Should I use CAGR for periods of less than one year?
Generally no. Annualising very short-term returns can produce exaggerated figures. For periods under a year, absolute return is usually more meaningful, as AMFI's investor education material also explains (Mutual Funds Sahi Hai: What is CAGR).
