Canadian Mortgage Math Note
Unlike US mortgages, Canadian mortgages compound semi-annually (twice per year), not monthly. This means the effective monthly rate is slightly different from the nominal annual rate divided by 12. For a complete list of Canadian mortgage terms and how they affect your renewal, see our mortgage renewal glossary.
Effective monthly rate = (1 + annual_rate / 2)^(1/6) − 1
Monthly payment = P × [r(1+r)^n] / [(1+r)^n − 1]
Where: P = principal, r = effective monthly rate, n = number of payments
