Annual Principal vs Interest

Understanding payment frequency

Making more frequent payments (like bi-weekly instead of monthly) can significantly reduce your total interest and shorten your loan term. For example, bi-weekly payments result in 26 payments per year (equivalent to 13 monthly payments), helping you pay off your mortgage faster. Adding annual lump sum payments accelerates this even more.

How Mortgage Insurance Works

The insurance premium is calculated as a percentage of your mortgage amount (not the home price). This premium is typically added to your mortgage principal, meaning you'll pay interest on it over the life of your loan.

Example: On a $280,000 mortgage with 15% down, the CMHC premium would be 2.80% × $280,000 = $7,840. This amount is added to your mortgage, bringing the total to $287,840.

💡 Tip: To see how CMHC insurance affects your payments, add the insurance premium to your home price in the calculator above. This will show you the true cost of borrowing with insurance included.

For insured mortgages (less than 20% down payment), the maximum amortization is 25 years. For uninsured mortgages (20% or more down), lenders may offer up to 30 years, though the federal government announced plans to allow 30-year amortizations for first-time buyers of new builds. Longer amortization reduces monthly payments but increases total interest paid.
