Formula Used in the Calculator

The calculator uses the following formula to determine your mortgage affordability:

Mortgage Affordability Formula

Maximum Mortgage Amount = [(Gross Monthly Income × 2.5) - Total Monthly Debt Payments - (Property Taxes + Insurance)] × (1 - Down Payment Percentage)

Where:

Gross Monthly Income = Your total monthly income before taxes
Total Monthly Debt Payments = All your monthly debt obligations excluding the mortgage
Property Taxes + Insurance = Annual property taxes and insurance costs
Down Payment Percentage = Your down payment as a percentage of the home price

The 2.5 multiplier is based on Ontario's mortgage stress test guidelines, which recommend that your total debt payments (including the mortgage) should not exceed 32% of your gross monthly income.

Worked Example

Let's calculate mortgage affordability for a person with:

Gross monthly income: $5,000
Total monthly debt payments: $1,200
Down payment: 20% ($100,000 on a $500,000 home)
Property taxes and insurance: $6,000 per year ($500 per month)

Calculation Steps

1. Calculate 2.5 times gross monthly income: $5,000 × 2.5 = $12,500

2. Subtract total monthly debt payments: $12,500 - $1,200 = $11,300

3. Subtract property taxes and insurance: $11,300 - $500 = $10,800

4. Apply down payment percentage: $10,800 × (1 - 0.20) = $8,640

Final maximum mortgage amount: $8,640

This means the person can afford a mortgage of approximately $8,640 per month for a $500,000 home with a 20% down payment.
