Mortgage Approval Calculator Ontario

Determine your mortgage approval in Ontario using this calculator. Based on your income, existing debts, and credit score, it estimates your maximum borrowing power. This tool helps you understand what mortgage amount you might qualify for before applying.

How the Mortgage Approval Calculator Works

The mortgage approval calculator estimates your maximum borrowing power in Ontario based on key financial factors. The calculation considers your income, existing debts, and credit score to provide an estimate of how much you might qualify for.

Key Factors Considered

Gross Monthly Income: Your total monthly income before taxes
Total Monthly Debt Payments: Existing loans, credit cards, and other obligations
Credit Score: Your creditworthiness (excellent, good, fair, or poor)
Down Payment: The amount you can contribute upfront

Formula Used

The calculator uses a simplified version of the mortgage approval formula:

Maximum Approval = (Income × 4.5) - Debt - Down Payment

This is then adjusted based on your credit score:

Excellent (720+): No adjustment
Good (660-719): 10% reduction
Fair (600-659): 20% reduction
Poor (Below 600): 30% reduction

Limitations

This calculator provides an estimate only. Actual mortgage approval depends on:

Your complete financial situation
Lender-specific requirements
Current market conditions
Your employment status

For precise approval, consult with a mortgage broker who can review your complete financial profile and access lender-specific criteria.

Worked Example

Let's calculate a mortgage approval for someone with:

Gross monthly income: $5,000
Total monthly debt payments: $1,200
Credit score: Good (680)
Down payment: $20,000

Step-by-Step Calculation

Calculate initial approval: ($5,000 × 4.5) - $1,200 - $20,000 = $22,500 - $1,200 - $20,000 = $1,300
Apply credit score adjustment (10% reduction for good credit): $1,300 × 0.9 = $1,170
Final estimated approval: $1,170

This example shows an estimated approval of $1,170 per month. The actual amount may vary based on lender requirements and your complete financial situation.
