Frequently Asked Questions
What is semi-annual compounding and why does it matter for Canadian mortgages?
Canadian mortgages use semi-annual compounding, which means interest is calculated and added to your loan twice per year (every 6 months). This is different from the US, which uses monthly compounding. The Canadian formula converts your annual rate to an effective monthly rate using the formula: monthlyRate = (1 + annualRate/2)^(1/6) – 1. This affects how much interest you'll pay and is required by Canadian lending regulations.
What is CMHC insurance and when do I need it?
CMHC (Canada Mortgage and Housing Corporation) insurance is mortgage default insurance required when your down payment is less than 20% of the home's purchase price. The insurance protects your lender if you default on the mortgage. The insurance premium is calculated as a percentage of your mortgage amount and is added to your total mortgage debt. It typically ranges from 2.8% to 4% depending on your down payment percentage.
What's the difference between biweekly and accelerated biweekly payments?
Standard biweekly payments are calculated by dividing your annual mortgage payment by 26 (since there are 26 biweekly periods in a year). Accelerated biweekly payments use a higher amount—typically dividing the monthly payment by 2 instead. This means you'll pay the equivalent of 13 monthly payments per year instead of 12, allowing you to pay off your mortgage faster and save on interest.
Can I change my mortgage payment frequency?
Yes, most Canadian lenders allow you to change your payment frequency during your mortgage term, though some may charge a fee. Switching to biweekly or accelerated payments is a popular way to build equity faster. Always check with your lender about available options and any associated costs before making changes.
What are the typical amortization periods available in Canada?
The most common amortization periods are 15, 20, 25, and 30 years. A shorter amortization means higher monthly payments but significantly less interest paid overall. For example, a 20-year mortgage will cost less in total interest than a 25-year mortgage at the same rate. Maximum amortization periods can extend to 40 years for certain insured mortgages, though this results in higher total interest costs.
