You purchase a three year certificate of deposit (CD) for $100,000 on January 1st, 2000. This CD has an annual interest rate of 5%. The interest compounds continuously. What is the balance for the CD account on July 1, 2001?
$105,000
$107,500
$107,593
$110,250
Answer: Formula of Continuous compounding-
FV = PV * ert
Where:
Given: PV = $100000, e = 2.7183 (constant), r = 5%, t = 1. 5 years (From Jan 1, 2000 to July 2001)
Putting the values in the formula we get:
Firstly we will calculate the Future value at the end of Year 1. So t = 1
FV = 100000 * 2.7183(.05*1)
FV = $107593
Now, we will calculate FV 1.5 years, i.e. 1 year 6 months
FV = 100000 * 2.7183 (.05*1.5)
FV = $107788
