Can anyone check and see if this is correct?This is what i got for my Monthly payment and Total interest problem.
We have been renting a small apartment but decide to purchase a house. we Found one that is selling for $400,000. we decide to make a 20% down payment on a 30-year mortgage at 3.75%.
Answer each of the following questions separately, showing all your work to reach each answer.
a. How much will they need for the down payment?
20% of $400,000.00 = .02 * 400,000 = $80,000
They will need to pay $80,000 for down payment.
b. What will be the mortgage amount (ie the principal)
The principal will be Total cost – down payment
400,000 – 80,000 = 320,000
The mortgage amount will be $320,000.00
c. How much will their monthly payment be for the principal and interest?
Using the monthly payment formula M = P(r/12)
————
1-(1+r\12)^-12t
P= 320000, r = 3.75% or 0.0375 , t = 30
M = 320000 (0.0375 / 12)
—————————–
1-(1+ 0.0375/12) ^-12(30)
M= $1481.97
d. How much total interest will they pay if they take the full 30 years to pay off the mortgage?
Total amount to repay the loan = 12 payments per year * 30 years = 360
360 * 1481.97 = 533509.2
533509.2 – 320000 = $213509.2 Total interest
Can someone confirm that i did this correctly ? Thank you
