Consider a $2,800 deposit earning 7 percent interest per year for six years.
What is the future value? (Do not round intermediate calculations. Round your answer to 2 decimal places.)
How much total interest is earned on the original deposit? (Do not round intermediate calculations. Round your answer to 2 decimal places.)
How much is interest earned on interest? (Do not round intermediate calculations. Round your answer to 2 decimal places.)
Answer a.
Amount deposited = $2,800
Interest rate = 7%
Period = 6 years
Future value = Amount deposited * (1 + Interest
rate)^Period
Future value = $2,800 * 1.07^6
Future value = $2,800 * 1.500730
Future value = $4,202.04
Answer b.
Total interest earned = Future value - Amount deposited
Total interest earned = $4,202.04 - $2,800.00
Total interest earned = $1,402.04
Answer c.
Simple Interest = Amount deposited * Interest rate *
Period
Simple Interest = $2,800 * 7% * 6
Simple Interest = $1,176.00
Interest earned on interest = Total interest earned - Simple
Interest
Interest earned on interest = $1,402.04 - $1,176.00
Interest earned on interest = $226.04
