Why are Canadian mortgage payments different from US mortgages?

By Canadian federal law, mortgage interest on fixed-rate loans is compounded semi-annually rather than monthly. This results in slightly lower effective monthly interest rates and monthly payments compared to US loans at the same nominal rate.

What is CMHC mortgage default insurance?

If your down payment is less than 20% of the purchase price, Canadian law requires mortgage default insurance (CMHC, Sagen, or Canada Guaranty). The premium ranges from 2.80% to 4.00% of the loan amount and is typically rolled into your total mortgage.

What is an accelerated bi-weekly mortgage payment?

An accelerated bi-weekly payment takes your regular monthly payment and divides it by two, paying that amount every two weeks (26 times a year). This effectively makes 13 full monthly payments annually, shaving years off your amortization and saving thousands in interest.

Formula

In Canada, fixed mortgages compound semi-annually. Monthly compounding rate r_m = (1 + r/2)^(2/12) - 1. Monthly Payment = P × [r_m(1 + r_m)ⁿ] / [(1 + r_m)ⁿ - 1].
