The CAGR full form is Compound Annual Growth Rate – the steady yearly rate at which an investment would have grown if it rose by exactly the same percentage every year. It turns a lumpy, multi-year return into one clean number. Useful for a lump sum, but misleading for an SIP.
It is the number every fund factsheet and headline leans on, because a single "grew X% a year" is far easier to compare than a jagged list of yearly ups and downs. That convenience is also its blind spot.
CAGR at a glance
What does CAGR stand for?
CAGR is short for Compound Annual Growth Rate. "Compound" is the important word: it assumes each year's gain is reinvested and earns its own gain the next year. So CAGR is not a simple average of yearly returns – it is the constant rate that, compounded year on year, takes your starting amount to your ending amount over the period.
Think of it as the answer to one question: "If this investment had grown by the same percentage every single year, what would that percentage be?"
How is CAGR calculated?
The formula is:
CAGR = (Ending value ÷ Beginning value)^(1 ÷ number of years) − 1
Take a clean example (the figures here are illustrative). You invest ₹1,00,000 and five years later it is worth ₹1,61,051.
- Ending ÷ beginning = 1,61,051 ÷ 1,00,000 = 1.61051
- Raise to the power 1/5 = 1.10
- Subtract 1 = 0.10, or 10% CAGR
The total, or absolute, return here is 61% – but spread across five compounding years, that is a 10% annual pace. This is why CAGR lets you compare a 3-year fund against a 10-year one on the same scale.
What CAGR hides: the ride
Here is the catch. CAGR only looks at the first value and the last value. Everything in between is erased.
Two funds can both show a 10% CAGR over five years and have felt nothing alike:
- Fund A climbed a smooth ~10% each year.
- Fund B fell 40% in year two, terrified everyone who owned it, then recovered.
Same start, same finish, same CAGR – wildly different experience. CAGR flatters the bumpy fund by hiding the drawdown that would have made you want to sell. When you read a CAGR, remember you are seeing the average speed, not the potholes.
Why CAGR is the wrong number for an SIP
CAGR assumes a single amount invested once, at the start. An SIP breaks that: you invest every month, so each instalment has its own holding period, and running a plain CAGR on "total invested versus final value" treats all that money as if it went in on day one, badly understating what an SIP investor actually earned. XIRR handles that – see what is XIRR, which weights every instalment by how long it was actually invested.
What counts as a "good" CAGR?
There is no universal pass mark, and no fund can promise a repeat of its past CAGR. A high trailing CAGR often just means you are looking at a period that ended on a market high. A fairer read is to compare a fund's CAGR against its own benchmark index and its category peers over the same window, and across several windows, not one flattering stretch.
Also watch the period length. A 1-year CAGR is really just a 1-year return and can swing violently; long-horizon CAGR (7–10 years) is far more meaningful for equity.

CAGR is a good storyteller and an honest one, as long as you remember what story it is telling: the average pace of a single investment, with the drama edited out. Read it for what it is, and reach for XIRR the moment you are investing month by month.
