Mortgage Formula

The monthly mortgage payment is calculated using this formula:

M = P [i(1 + i)^n] / [(1 + i)^n - 1]

Where:
M = Monthly payment
P = Principal loan amount (Purchase price - Down payment)
i = Monthly interest rate (Annual rate / 12 / 100)
n = Number of payments (Amortization period × 12)

This formula calculates the fixed monthly payment for a mortgage with a fixed interest rate.

Example Calculation

Let's calculate a mortgage for a $500,000 home with a 20% down payment, 5% interest rate, and 25-year amortization:

Down payment: 20% of $500,000 = $100,000
Principal: $500,000 - $100,000 = $400,000
Monthly interest rate: 5% ÷ 12 = 0.4167%
Number of payments: 25 × 12 = 300
Using the formula: M = $400,000 [0.004167(1.004167)^300] / [(1.004167)^300 - 1]
Result: Monthly payment = $2,720.66

This example shows the monthly payment for this scenario. Your actual payment may vary based on your specific circumstances.

Ontario-Specific Considerations

Property Taxes

In Ontario, property taxes are calculated based on the assessed value of your home. The average property tax rate in Ontario is about 1.25% of the assessed value. You can estimate your property taxes by multiplying your home's assessed value by this rate.

Mortgage Stress Test

Ontario requires mortgage lenders to perform a stress test to ensure borrowers can handle higher interest rates. The test compares your mortgage payments at both the current rate and a higher rate (typically 2% above the current prime rate).

CMHC Insurance

If you put down less than 20% of the home price, you may need to pay CMHC insurance (Canada Mortgage and Housing Corporation). This insurance protects lenders if you default on your mortgage. The cost is typically 2.85% to 4.05% of the mortgage amount, depending on your down payment.

First-Time Home Buyer Incentives

Ontario offers various incentives for first-time home buyers, including:

First-Time Home Buyer Tax Credit (up to $8,000)
Home Buyers' Plan (HBP) for down payment assistance
First-Time Home Buyer Program (FTHBP) for low-income buyers
