Calculation Process
The calculator follows these steps to determine your mortgage affordability:

- Determine your maximum mortgage payment based on your income and debt ratio
- Calculate the maximum home price you can afford based on your down payment and mortgage amount
Note: This calculator provides an estimate. Actual affordability may vary based on your specific financial situation and mortgage terms.

Where:
- Gross Monthly Income: Your total monthly income before taxes
- Maximum Debt Ratio: The maximum percentage of your income that can be allocated to debt payments (typically 40% in Ontario)

The calculator then calculates the maximum home price based on your down payment and mortgage amount:
Worked Example
Let's walk through an example to see how the Ontario Mortgage Affordability Calculator works.
Example Scenario
- Gross Monthly Income: $5,000
- Down Payment: 20%
- Interest Rate: 5%
- Amortization Period: 25 years
Calculation Steps
- Calculate the maximum mortgage amount:
Maximum Mortgage Amount = ($5,000 × 0.40) - ($5,000 × 0.36) = $2,000 - $1,800 = $200
- Calculate the maximum home price:
Maximum Home Price = ($200 / (1 - 0.20)) × 0.20 = ($200 / 0.80) × 0.20 = $250 × 0.20 = $50
In this example, the calculator estimates that you can afford a home priced at $50,000 with a $10,000 down payment and a $40,000 mortgage.
Note: This is a simplified example. Actual results may vary based on your specific financial situation and mortgage terms.
