You want to purchase a home. cost \$165,000. you have \$40,000 downpayment. you want to finance rest at 3.5% for 15 years. how much will monthly mortgage be? How much in total will you pay over the 15 years even counting the downpayment? I came up with payment of \$893.6 for first part. Again, I am not too sure if I am entering correctly into the calculator.

• Bus Finance -

balance after downpayment = 125000
i = .035/12 = .002916666... (I stored in memory of calculator)
n = 180

125000 = paym (1 - 1.002916666..^-180)/.00291666
payment = 893.60 , you are correct.

take it from there, that was the hard part

to continue. it asks how much in total you will pay over the 15 years based on mortgage and down payment. I used the (893.60*12)(15)+40,000=200848.00. It then asks what portion of that is interest. I used the 200848.00FV 125000PV 180N with the I/YR=3.17%.

• Bus Finance -

since we paid back a total of 200848 on the original loan of 165000, the difference, or 35848 must have been interest.
