How the Canadian calculation works

In Canada, fixed mortgage rates are quoted as a nominal rate compounded semi-annually, not in advance. To get your payment, we first convert it to an equivalent periodic rate:

  • Periodic rate = (1 + annual rate ÷ 2)2 ÷ payments per year − 1
  • Payment = principal × r ÷ (1 − (1 + r)−N), where N is the total number of payments

This is the same math your bank uses for a standard payment schedule. "Accelerated" bi-weekly payments (half the monthly amount, 26 times a year) pay the mortgage off faster — we don't model those here.

Keep in mind

  • These figures ignore mortgage default insurance, property tax, and maintenance.
  • Your actual rate at renewal will differ — this shows the full amortization at today's rate.
  • Not financial advice. Confirm with your lender before making decisions.
