Calculate mortgage payments for Canadian properties

Description

The Canadian Mortgage Calculator is built specifically for the unique rules of the Canadian real estate market. It accounts for semi-annual interest compounding (standard in Canada), estimates mandatory CMHC Insurance for down payments under 20%, and supports multiple payment frequencies like Bi-Weekly and Accelerated Bi-Weekly.

Inputs

  • Home Price: The total purchase price ($).
  • Down Payment: The initial cash contribution ($).
  • Interest Rate: The annual interest rate (%) (Note: Compounded semi-annually per Canadian law).
  • Amortization (Years): The total length of the mortgage (max 25 years for insured loans).
  • Payment Frequency: Choose between Monthly, Bi-Weekly, or Accelerated Bi-Weekly.

Outputs

  • Payment Amount: Your installment based on the selected frequency ($).
  • CMHC Insurance (Est.): The estimated one-time premium added to your loan if your down payment is less than 20% ($).
  • Total Loan Amount: The base loan plus the CMHC insurance premium ($).

“Good to Know”

  • Semi-Annual Compounding: In Canada, fixed-rate mortgage interest is compounded twice a year, not monthly. This results in an “effective rate” that is slightly different from US mortgages.
  • CMHC Insurance: If your down payment is between 5% and 19.99%, you must pay for mortgage default insurance. This fee is usually added to your loan.
  • Accelerated Bi-Weekly: This popular option effectively makes one extra monthly payment per year, helping you pay off your mortgage several years faster and saving significant interest.

Examples

Example 1: Standard Ontario Purchase

  • Input:
    • Price: $500,000, Down: $50,000 (10%)
    • Rate: 5.0%, Frequency: Monthly
  • Output:
    • CMHC: ~$14,000
    • Monthly: ~$2,700

Example 2: Accelerated Savings

  • Input:
    • Frequency: Accelerated Bi-Weekly
  • Output:
    • Shows a lower individual payment amount but demonstrates how the mortgage balance drops faster over time compared to monthly.

Example 3: 20% Down (No CMHC)

  • Input:
    • Down: $100,000 (20%)
  • Output:
    • CMHC: $0
    • (Shows the benefit of reaching the 20% threshold to avoid insurance costs).
