Math Problem Statement

If an asset declines in value from $5,000 to $3,800 over nine years, what is the mean annual growth rate in the asset’s value over these nine years? Enter your answer as a percentage. If needed, round your answer to two decimal digits.

Solution

To find the mean annual growth rate of an asset that declines in value from $5,000 to $3,800 over nine years, you can use the formula for the compound annual growth rate (CAGR):

CAGR=(Final ValueInitial Value)1n1\text{CAGR} = \left(\frac{\text{Final Value}}{\text{Initial Value}}\right)^{\frac{1}{n}} - 1

Where:

  • Final Value = $3,800
  • Initial Value = $5,000
  • nn = 9 years

Let's calculate it:

CAGR=(38005000)191\text{CAGR} = \left(\frac{3800}{5000}\right)^{\frac{1}{9}} - 1

First, compute the ratio:

38005000=0.76\frac{3800}{5000} = 0.76

Then, raise this ratio to the power of 19\frac{1}{9}:

0.76190.97150.76^{\frac{1}{9}} \approx 0.9715

Finally, subtract 1 and convert to a percentage:

CAGR=(0.97151)×1002.85%\text{CAGR} = (0.9715 - 1) \times 100 \approx -2.85\%

So, the mean annual growth rate is approximately -2.85%.

  1. How is the compound annual growth rate different from the simple average rate of change?
  2. What is the significance of a negative growth rate?
  3. How would the CAGR change if the time period was longer?
  4. Can CAGR be used for assets with non-linear growth?
