Question 1118845: In one instance, a financial institution loaned you $70,000 for two years at an APR of 6.75% for which you must make monthly payments. In a second instance, you loaned a financial institution $70,000 for two years at an APR of 6.75% compounded monthly. What is the difference in the amount of interest paid? (Round your answer to the nearest cent.)
Answer by Theo(13342) (Show Source): You can put this solution on YOUR website!
the monthly payments on the loan to you from the bank are equal to $3,126.153065.

the total payments you made are equal to 24 times that = $75,027.67355.

the total interest you paid is equal to that minus the original loan amount of $70,000 = $5,027.67355.

when you deposit $70,000 in the bank for 2 years at 6.75% per year compounded monthly, the future value of that amount will be $80,087.27459.

the interest earned is that minus the original amount you invested of $70,000 = $10,087.27459.

i used the TI-BA-II financial calculator to get these results.

to calculate what the monthly payment would be, the inputs were:

present value = 70,000.
future value = 0.
interest rate per month = 6.75/12.
number of months = 2 * 12.
payments are made at the end of each month.

i then had the calculator give me the monthly payment.

to calculate what the future value of the 70,000 deposit into the bank would be, the inputs were:

present value = 70,000.
payment per month = 0.
interest rate per time period = 6.75/12.
number of time periods = 2 * 12.

i then had the calculator give me the future value.
