Monthly Rate i = (1 + r / 2)^(2 / 12) - 1; Payment = P × [i(1 + i)^n] / [(1 + i)^n - 1]Under the Canadian Bank Act, fixed-rate mortgages must be compounded semi-annually, not monthly. This results in an effective monthly interest rate slightly lower than in the United States.

Under the federal Canadian Bank Act, fixed mortgage rates must compound semi-annually rather than monthly. This formula results in slightly lower total interest costs compared to US monthly compounding.
Accelerated bi-weekly simply divides your monthly payment by 2 and takes 26 payments a year. Since 26 half-payments equals 13 full payments, you pay an extra full monthly payment towards principal every year, shaving about 3.5 years off a 25-year mortgage.
Accelerated bi-weekly divides the regular monthly payment by two and pays every two weeks (26 payments per year). This equals paying 13 full monthly payments every year, shaving approximately 3 to 4 years off a 25-year amortization.
