A variation of growth rate that is frequently used to evaluate the performance of an investment or business is the compound annual growth rate (CAGR).
The CAGR, which is not an actual return rate but rather a representation, shows the rate of growth that would have occurred had earnings been reinvested at the end of each year and the investment expanded at the same pace each year.
The CAGR calculation formula is as follows:
CAGR = (SV / BV) ^ (1 / n) – 1
SV=Ending value
BV=Beginning value
n=Number of years
In the formula above, EV represents the investment's future value, BV denotes its present value, and n is the number of years the investment will last.
Let's look at a fictitious scenario to better understand the calculation. Consider your 2015 investment of $20,000 in a mutual fund. In 2020, the investment will be worth $35,000. The methodology yields the following CAGR for this mutual fund investment:
CAGR= (35000/ 20000) ^ (1/5) – 1 = 11.84%
The CAGR calculation assumes that growth is steady over a specified period of time. CAGR is a widely used metric due to its simplicity and flexibility, and many company will use it to report and forecast earnings growth, called
run rate.
