Answer:
save money = $20198.40
Explanation:
given data
financing amount = $340,000
time period = 30 year
rate with 3 point = 6.475%
rate without point = 6.85%
solution
first we get here monthly payment at 6.475% that is in excel we get
monthly payment = PMT(6.475%/12, 30×12, -340000)
monthly payment = $2143.44
so here pay total interest will be
total interest = $2143.44 ×(30×12) -340000 + (340000 ×3%)
total interest = $441838.40
and
monthly payment at 6.85% that is in excel we get
monthly payment = PMT(6.85%/12, 30×12, -340000)
monthly payment = $2227.88
so here pay total interest will be
total interest = $2227.88 ×(30×12) -340000
total interest = $462036.80
so here money save over this loan amount is
save money = $462036.80 - $441838.40
save money = $20198.40
