We make investments to earn returns. Investment return is the change in
value of an investment over a given period of time. For example
Initial
Amount Profit/Loss
Profit/Loss(in for the Percentage(in the
Description the period) period period)
Return in year 100*( 20,000/10,000
2010-11 20,000 10,000 ) = 200%
100 *(-
Return in year 15,000/30,000) =
2011-12 -15,000 30,000 -50%
Absolute
Returns from 15,000-10,000 100*(5,000/10,000)
Apr 2010-2012 =5000 10,000 = 50%
Simple 5000 in 2 years 10,000 100*(5000/10,000 *
Annualized
Return
from Apr 2010-
2012 2)= 25%
CAGR is a way to smoothen out the returns, it determines an annual
growth rate on an investment whose value has fluctuated from one
period to the next as shown in picture below. In that sense CAGR isn’t
the actual return in reality. This is similar to saying that you went on a
trip and averaged 60 km/hr. Whole time you did not actually travel 60
km/hr Sometimes you were traveling slower, other times faster.
CAGR graph
The formula to calculate CAGR is :
CAGR Formula
So CAGR for above example is :
= ((15,000/10,000) ^ (1/2)) -1
= 22.47%
If the investment states that it had an 8% annualized return over ten
years, that means if you invested on Apr 1, and sold your investment on
Mar 31 exactly ten years later, you earned the equivalent of 8% a year.
However, during those ten years, one year the investment may have
gone up 20% and another year it may have gone down 10%. In the
example if the investment Rs 10,000 would have grown at the rate of
22.47% every year and at end of two years it would be Rs 15,000 as
shown in calculation below.
Year Price
0 5,000
1 22,000
2 5,000
This could be viewed as a great investment if you were smart enough to
buy at 5,000 and one year later sell it at 22,000 for a 340% gain. But if
one more year later the price was 5 ,000 and you still have it in you
would be even. If you bought XYZ in year 1 at 22,000 and still had it in
Year 2, you would have lost 77% of your value (from 22,000 to 5,000).
Ads can tout a fund’s 20% CAGR in bold type, but the time period used
may be from the peak of the last bubble, which has no bearing on the
most recent performance. More Details about CAGR

Rolling Returns
Returns that we have looked at so far have used the value of investment
at beginning and at end of the period. But does that tell the full
story. Suppose there two investments, A and B, both purchased for 12
and both sold seven years later for 32 as shown in figure below.
