Key Facts
- Formula: CAGR = (Ending Value ÷ Starting Value)1/n – 1, where n is the number of years.
- CAGR shows one smoothed annual rate. It hides the actual up-and-down path your fund took.
- For SIPs, use XIRR, not CAGR. XIRR accounts for multiple investment dates.
- Standard industry practice treats CAGR as the norm for showing mutual fund returns of one year or more. Shorter periods use absolute return. (Verify against the current SEBI Master Circular for Mutual Funds before publishing. Last checked September 2026.)
- A higher CAGR is not automatically “safer.” It says nothing about how bumpy the ride was.
Say a friend tells you their mutual fund gave 80% returns in five years, and another says theirs gave 12.5% CAGR. Which one grew faster? You cannot tell – because one number covers five years and the other covers one. This mix-up trips up a lot of first-time investors.
CAGR fixes this. It converts any return, over any time period, into one comparable, per-year number. So you can compare a 3-year fund to a 7-year fund on equal terms. This guide covers the formula, a worked example, and when to use CAGR versus XIRR.
CAGR vs Absolute Return vs XIRR: What’s the Difference?
| Metric | What it shows | Best used for |
|---|---|---|
| Absolute Return | Total gain over the whole period, with no time factor | Lump-sum investments held under 1 year |
| CAGR | One smoothed annual growth rate | Lump-sum investments held 1 year or more |
| XIRR | Annual rate that accounts for multiple, uneven cash flows | SIPs, or any investment with several transactions on different dates |

How Do You Calculate CAGR? A Step-by-Step Example
The formula has three inputs: your starting value, your ending value, and the number of years in between.
CAGR = (Ending Value ÷ Starting Value)1/n – 1
Worked example:
Suppose you invested ₹1,00,000 as a lump sum. After 5 years, it grew to ₹1,80,000.
Step 1: Ending ÷ Starting = 1,80,000 ÷ 1,00,000 = 1.80
Step 2: Raise to the power of 1/5 (n = 5 years) = 1.800.2 = 1.1247
Step 3: Subtract 1 = 0.1247, or 12.47% CAGR
Notice the gap: your total gain was 80% (absolute return), but your annual growth rate was only 12.47%. Both numbers are correct. They just answer different questions.
You don’t need to calculate this by hand every time. Every fund factsheet, and most investment apps, display CAGR for periods over one year. But knowing the formula helps you spot when a number looks wrong, or when two apps show different figures for the same fund.
Why Does Your App Show a Different CAGR Than the Factsheet?
Three reasons usually explain this. First, the “as of” date differs – even a one-day gap changes the ending value. Second, one source may compute CAGR based on NAV including any dividend or IDCW payouts, and another may not. Third, apps sometimes round n (the number of years) to a whole number. The exact figure uses days ÷ 365 instead.
So if two sources show a small difference, it’s rarely an error. Check the “as of” date first before assuming something is wrong.
Should You Use CAGR or XIRR for Your SIP?
Use XIRR, not CAGR, for a SIP. Here’s why. A SIP is not one lump sum – it’s 12, 36, or 60 separate small investments, each made on a different date. CAGR assumes a single starting value on a single date. It cannot handle multiple cash flows correctly.
XIRR solves this. It calculates one annual rate that accounts for the exact date and amount of every instalment. So when your SIP statement or app shows “XIRR,” that is the correct like-for-like comparison to a lump-sum fund’s CAGR.
What Counts as a Good CAGR for a Mutual Fund?
There’s no universal “good” number – it depends on the fund category, the time period, and the benchmark. A large-cap equity fund and a debt fund should never be judged by the same CAGR yardstick, because they carry very different risk levels. Please verify current category-wise return benchmarks from AMFI or the fund’s own factsheet before comparing any specific figure.
A more useful habit: compare a fund’s CAGR to its own benchmark index over the same period. Skip the arbitrary “good returns” number you saw online.
Limitations of CAGR You Should Know
CAGR smooths out volatility, so it hides risk. A fund that grew steadily and a fund that crashed 40% then recovered can show the exact same 5-year CAGR. But an investor who needed money during the crash lived a very different experience.
Because of this, never read CAGR alone. Look at it alongside the fund’s category, its volatility, and how consistently it has performed across market cycles.
Frequently Asked Questions
Q1. What is CAGR in simple words?
CAGR is the steady, year-on-year growth rate that would take your investment from its starting value to its ending value. It assumes the same growth rate every single year, smoothing the actual ups and downs into one average number.
Q2. Is CAGR the same as annual return?
Not quite. “Annual return” often refers to the return in one specific calendar year, which can swing a lot year to year. CAGR is a multi-year average, calculated over the whole holding period, so it reads smoother than any single year’s actual return.
Q3. Can I calculate CAGR without a financial calculator?
Yes. Divide your ending value by your starting value. Then use the y-to-the-x button on any scientific calculator app to raise that result to the power of (1 ÷ number of years), and subtract 1. Many mutual fund websites also offer a free CAGR calculator tool.
Q4. Why is my fund’s CAGR lower than the return I remember seeing?
You may be comparing CAGR to absolute (total) return, which is always a bigger-looking number over multi-year periods. Also check whether the “as of” date, and whether dividend/IDCW payouts, were included in each calculation.
Q5. Should I use CAGR or XIRR to judge my SIP?
Use XIRR for a SIP. CAGR assumes one lump-sum investment on one date, so it cannot correctly measure a SIP’s multiple monthly instalments. XIRR is built to handle exactly that.
Q6. Does a higher CAGR always mean a better fund?
No. CAGR says nothing about risk or consistency. Please compare CAGR only within the same fund category and against the fund’s own benchmark, not across unrelated fund types.
