Quick answer

Your maximum mortgage depends on four things: gross income, credit score, monthly debts, and the qualifying rules your lender uses (debt ratios, stress-test rate). In Canada lenders use GDS/TDS (rough guide: 39%/44%). In the U.S. many lenders look at debt-to-income (DTI) — often 43%–50% depending on loan type and compensating factors.

How lenders calculate maximum mortgage (step-by-step)

• Convert annual income to gross monthly income. Example: $120,000/year = $10,000/month.
• Apply the lender’s housing ratio. In Canada use GDS 39%: 0.39 × $10,000 = $3,900 allowed for housing costs (mortgage payment + taxes + heat + condo fees).
• Subtract expected property taxes and condo/other housing fees to get the potential mortgage payment.
• Convert that monthly payment to principal using the mortgage rate and amortization. Use an online mortgage calculator or this quick rule of thumb:

• At 5% interest, 25-year amortization, monthly payment per $100,000 ≈ $585.
• So a $2,915 mortgage payment ≈ $2,915 / $585 × $100,000 ≈ $498,000.

• Check total debt: lenders also test Total Debt Service (TDS) or DTI. Add monthly debts (car, credit cards) and ensure total is under the lender’s TDS/DTI cap.

Key numbers you control

• Credit score: higher score increases your borrowing power and lowers rate.
• Down payment: larger down payment reduces loan amount and may eliminate mortgage insurance.
• Debt reduction: paying off consumer debt raises your maximum.
• Rate shopping: lower interest or longer amortization raises your buying power.

Example calculation (clear)

Gross monthly income: $8,333 GDS max: 39% → housing budget = $3,250 Assume taxes/condo/heat = $500 → available monthly mortgage payment = $2,750 Using 5% / 25-yr → payment per $100k ≈ $585 → estimated mortgage ≈ $2,750 / $585 × $100,000 ≈ $470,000 Final usable mortgage depends on downstream TDS check and stress test.

Practical checklist to maximize your approved mortgage

• Get a free pre-approval. It locks in the qualifying number and identifies weak points.
• Improve credit score (short-term: correct errors; mid-term: reduce balances).
• Lower debts before applying.
• Increase down payment to lower loan-to-value (LTV) and avoid insurance.
• Lock a lower rate or choose longer amortization only when it makes sense.

Bottom line and immediate action

You can estimate your maximum mortgage in 10 minutes using your pay stubs and a mortgage calculator. For an accurate number based on local rules and the current stress-test rate, get a pre-approval.
