Explanation / Answer

a) Using the PMT function fo excel,

Annual payment = PMT(11.4%,50,-445000) = $50960

Using formula:

M = P(1+r)n r / [(1+r)n-1]

where M = yearly payment, r = rate of interest per period of payment and n number of payments, P = loan amount

M = 445000*((((1+11.4%)^50)*11.4%) /(((1+11.4%)^50)-1)) = $50960

b)

Total interest payment = total payment - borrowed amount = $50960 x 50 - $445000 = $2103000

c)

Half the payment is made at the end of 25 years.

Amortization Schedule for the first 25 years:

c)

Total Interest paid in the first 25 years = $1246025

% of total interest paid = $1246025 / $2103000 = 59.25%

d)

Total principal paid in the first 25 years = $27975

% of principal amount paid = $27975 / $445000 = 6.29%
