The calculator will show you the maximum mortgage amount you can afford based on Ontario's affordability guidelines.

Formula Used

The house affordability calculation in Ontario is based on the following formula:

Maximum Mortgage Amount

Maximum Mortgage = (Annual Income × 2.5) × (1 - Down Payment Percentage) / (Mortgage Rate × Amortization Factor)

The amortization factor is calculated as:

Amortization Factor = (1 + (Mortgage Rate / 12))^(Amortization Period × 12) - 1 / (Mortgage Rate / 12)

This formula follows Ontario's affordability guidelines which recommend that your mortgage payments should not exceed 2.5 times your annual income.

Worked Example

Let's calculate the maximum mortgage amount for someone with:

Annual income: $80,000
Amortization period: 25 years
Down payment: 10%
Mortgage rate: 5.00%

Using the formula:

Calculate the maximum mortgage amount: ($80,000 × 2.5) × (1 - 0.10) / (0.05 × Amortization Factor)
Calculate the amortization factor: (1 + (0.05/12))^(25×12) - 1 / (0.05/12) ≈ 13.54
Final calculation: ($200,000 × 0.90) / (0.05 × 13.54) ≈ $29,412

This means you could afford a mortgage of approximately $294,118 for a home with a 10% down payment.
