The total monthly payment includes principal, interest, and property taxes.

Worked Example

For a $400,000 home with a 20% down payment, 5% interest rate, 25-year term, and $3,000 annual property taxes:

1. Down payment: $400,000 × 20% = $80,000
2. Loan amount: $400,000 - $80,000 = $320,000
3. Monthly interest rate: 5% / 12 = 0.4167%
4. Number of payments: 25 × 12 = 300
5. Monthly payment: $320,000 × (0.004167(1 + 0.004167)^300) / ((1 + 0.004167)^300 - 1) ≈ $2,150
6. Monthly property tax: $3,000 / 12 = $250
7. Total monthly payment: $2,150 + $250 = $2,400

This example shows that your total monthly payment would be approximately $2,400.

Ontario Mortgage Rules

Ontario has specific mortgage rules that affect your payments:

• Strata fees and condo fees are additional monthly costs
• Mortgage default insurance may apply for down payments under 20%
• Interest deductions are available for primary residences
• CMHC insurance may be required for down payments under 5%

These additional costs are not included in the basic calculation but should be considered when budgeting for your new home.
