Answer
After 5 years, you will have earned approximately $11.29 in profit.
Solution
To determine the profit earned from a Certificate of Deposit (CD) with the given parameters, we’ll use the compound interest formula:
Where:
-
= the amount of money accumulated after years, including interest. -
= the principal amount ($1,500). -
= annual interest rate (in decimal form). -
= number of times interest is compounded per year. -
= time the money is invested for in years.
Given:
-
- APR (
) = 0.15% or 0.0015 in decimal. - Compounded monthly (
). - Time (
years).
Plugging in the values:
Profit Earned:
Therefore, the profit earned after 5 years is approximately $11.29.

Bonus Knowledge
To calculate the profit earned on a certificate of deposit (CD), we can use the formula for compound interest:
Where:
-
is the amount of money accumulated after n years, including interest, -
is the principal amount (the initial deposit), -
is the annual interest rate (decimal), -
is the number of times that interest is compounded per year, -
is the time the money is invested for in years.
In this case:
-
-
(which is as a decimal) -
(as interest is compounded monthly), -
.
Now we can plug in the numbers:
Calculating the components:
Calculating
:
Now substitute this back into the equation:
Now to find the profit, subtract the principal from the amount:
So, when you redeem the CD in 5 years, you will have earned approximately $11.45 in profit.
