After 15 years, the future value of your investment is $3,172.17 if it is a compound interest and $2,200 if it is a simple interest.
The formula for the future value of compound interest is:
FV = P (1 + r)ⁿ
Where:
P = present value or initial balance
r = annual interest rate
n = number of years
Parameters given from the problem:
P = $1,000
r = 8% = 0.08
n = 15
Hence,
FV = 1000 (1 + 0.08)¹⁵
FV = 3,172.17
The formula for the future value of simple interest is:
FV = P (1 + r.n)
Hence,
FV = 1000 (1 + 0.08 × 15)
FV = 2,200
You will have $3,172.17 if the account pays 8% compound interest and you will have $2,200 if the account pays 8% simple interest.
