Compound Annual Growth Rate (CAGR)

What is Compound Annual Growth Rate (CAGR)?§

The Compound Annual Growth Rate (CAGR) is the mean annual growth rate of an investment over a specified time period, assuming that the profits are reinvested at the end of each period. It’s your investment’s best friend, providing a smooth and clean annual return that wipes away all the volatility and gives you a reliable number you can count on—like counting on your cat to ignore you when you call its name.

Formula:§

To calculate CAGR, you can use the following formula:

$$\text{CAGR} = \left( \frac{\text{Ending Value}}{\text{Beginning Value}} \right)^{\frac{1}{\text{n}}} - 1$$

Where:

• Ending Value is the value of the investment at the end of the period.
• Beginning Value is the value of the investment at the start of the period.
• n is the number of years.

CAGR vs Average Annual Return Comparison§

Related Terms§

• Compound Interest: Interest calculated on the initial principal and also on the accumulated interest from previous periods.
• Annualized Return: The geometric average amount of money earned by an investment each year over a given time period.

Example§

Let’s say you invested $1,000 in a stock, and after 5 years, it grew to $1,500. Using the CAGR formula, we get:

$$CAGR = \left( \frac{1500}{1000} \right)^{\frac{1}{5}} - 1 \approx 0.08447 \text{ or } 8.45$$

So, the smoothed annual growth rate of your investment is approximately 8.45%. Not bad for a capital growth that could have otherwise been less than stellar after a few wild market swings!
