The price of a small cabin is
$55 comma 00055,000.
The bank requires a 5% down payment. The buyer is offered two mortgage options: 20-year fixed at
9.59.5%
or 30-year fixed at
9.59.5%.
Calculate the amount of interest paid for each option. How much does the buyer save in interest with the 20-year option?
Step 1: Price of the small cabin = $55,000
Down payment = 5% of Price of the small cabin = 5% *$55,000 = $2,750
Therefore, loan amount = Price of the small cabin - Down payment
= $55,000 - $22,750 = $52,250
The buyer is offered two mortgage options: 20-year fixed at 9.5%
We can use Present value (PV) of an Annuity formula to calculate the annual payment of loan
PV = PMT * [1-(1+i) ^-n)]/i
Where PV (principal amount) = $52,250
PMT = Annual payment =?
n = N = number of payments = 20 years
i = I/Y = interest rate per year = 9.5%
Therefore,
$52,250 = PMT* [1- (1+9.5%)^-20]/9.5%
= $5,929.16
Annual payment is $5,929.16
Total payment = number of payments * Annual payment = 20 *$5,929.16
=$118,583.15
Therefore total interest payment = Total payment - principal payment
= $118,583.15 - $52,250
= $66,333.15
Sep 2: The buyer is offered two mortgage options: 30-year fixed at 9.5%
We can use Present value (PV) of an Annuity formula to calculate the annual payment of loan
PV = PMT * [1-(1+i) ^-n)]/i
Where PV (principal amount) = $52,250
PMT = Annual payment =?
n = N = number of payments = 30 years
i = I/Y = interest rate per year = 9.5%
Therefore,
$52,250 = PMT* [1- (1+9.5%)^-30]/9.5%
= $5,312.81
Annual payment is $5,312.81
Total payment = number of payments * Annual payment = 30 * $5,312.81
= $159,384.32
Therefore total interest payment = Total payment - principal payment
= $159,384.32 - $52,250
= $107,134.32
The buyer save in interest with the 20-year option = Total interest payment in 30 years option - Total interest payment in 20 years option
= $107,134.32 - $66,333.15
= $40,801.17
Therefore the buyer saving in interest with the 20-year option is $40,801.17
