Beyond the Answer
Let’s first calculate the future value of the investment compounded annually. The formula for calculating future value (FV) when compounded annually is:
Where:
-
is the principal amount ($2000), -
is the annual interest rate (9% or 0.09), -
is the number of years (10).
So for compounding annually, we have:
Now, let’s calculate the future value of the investment compounded periodically. The formula for future value when compounded periodically with
times a year is:
In this case, the investment is compounded 12 times a year (monthly), so
:
Now, we calculate how much more the investment compounded periodically is worth compared to the investment compounded annually:
Thus, after 10 years, the investment compounded periodically will be worth approximately
more than the investment compounded annually.
