Cost of Borrowing: A Definition in Mortgage Financing
COST OF BORROWING
Calculation of the APR
APR = {C / (T x P)} x 100
For the purpose of section 7.2 of the Act, the cost of borrowing for a mortgage is the annual rate on the principal as calculated using the formula, in which,
"APR" is the annual percentage rate cost of borrowing,
"C" is the cost of borrowing within the meaning of section 5 over the term of the mortgage,
"P" is the average of the principal of the mortgage outstanding at the end of each period for the calculation of interest under the mortgage, before subtracting any payment that is due at that time, and
"T" is the term of the mortgage in years, expressed to at least two decimal points of significance.
For the purpose of subsection (1),
the APR may be rounded off to the nearest eighth of a per cent;
each instalment payment made on the mortgage must be applied first to the accumulated cost of borrowing and then to the outstanding principal;
a period of,
one month is 1/12 of a year,
one week is 1/52 of a year, and
one day is 1/365 of a year;
if the annual interest rate underlying the calculation is variable over the period of the mortgage, it must be set as the annual interest rate that applies on the day that the calculation is made;
if there are no instalment payments under the mortgage, then the APR must be calculated on the basis that the outstanding principal is to be repaid in one lump sum at the end of the term of the mortgage; and
a mortgage for an amount that comprises, in whole or in part, an outstanding balance from a prior mortgage is a new mortgage for the purpose of the calculation.
The cost of borrowing for a line of credit or credit card secured under a mortgage is,
if the mortgage has a fixed annual interest rate, that annual interest rate; or
if the mortgage has a variable annual interest rate, the annual interest rate that applies on the date of the disclosure.

Subject to subsection (2), the cost of borrowing for a mortgage, other than one that secures a line of credit, consists of all the costs of borrowing under the mortgage over its term and including the following charges:

if the insurance is optional, or
if the borrower is its beneficiary and the amount insured reflects the value of an asset that is security under the mortgage;
charges for an overdraft;

penalty charges for the prepayment of the mortgage;
