Consider a home mortgage problem. The house in question will cost $200,000. The down payment is 20%, or $40,000, which means the loan will be for $160,000. The loan will be a 15-year loan. The annual interest rate (APR) is 3.5%. Payments to the bank are monthly. Address the following:
Monthly loan payment is calculated using PMT function in Excel :
rate = 3.5% / 12 (converting annual rate into monthly rate)
nper = 15*12 (15 year loan with 12 monthly payments each year)
pv = 160000 (loan amount)
PMT is calculated to be $1,143.81
Interest in any month = principal outstanding at beginning of month * 3.5% / 12
Principal portion of monthly payment = monthly payment minus interest portion of payment
principal outstanding at end of month = principal outstanding at beginning of month minus principal portion of monthly payment
total monthly cash outflow = $1,143.81 + $100 + $100 + $125 = $1,468.81
