Ann borrowed $500,000 to purchase an apartment in Port Melbourne. The
loan requires monthly repayments over 15 years. When she borrowed the
money the interest rate was 6 percent per annum, but 2 years later the bank
increased the interest rate to 7 percent per annum, in line with market rates.
The bank tells Ann she can
• increase her monthly repayment (so as to pay off the loan by the
originally agreed date) (First Option) or
• she can extend the term of the loan (and keep making the same
monthly repayments) (Second Option).
a) The new monthly repayment if Ann accepts the first option;
N 15 X 12
COMP PAYMENT $4219
N 13 X 12
COMP PAYMENT 4463
b) The extra period to the loan term if Ann accepts the second option.
