Fixed-rate payments use Canadian semi-annual compounding. When the down payment is below 20%, the purchase-price estimate includes the applicable default-insurance premium. A 30-year insured estimate also includes the extended-amortization surcharge and assumes the buyer or property meets current eligibility rules.

This estimate uses configured GDS/TDS caps and a qualifying-rate assumption. A real pre-approval may produce a different result based on lender policy, credit, property, documentation, and current rules.
Frequently asked questions
How much mortgage can I qualify for in Ontario?
The estimate depends on gross income, housing costs, monthly debts, down payment, amortization, and the qualifying rate. This calculator uses configured 39% GDS and 44% TDS guidelines, but lender criteria may be more restrictive and approval is not guaranteed. Use the GDS/TDS calculator to see which expenses are driving the ratios before comparing a comfortable budget with the estimated maximum.
What is the difference between maximum mortgage and purchase price?
Maximum mortgage is the estimated financed amount supported by the calculator's income, debt, and qualifying-rate assumptions. Maximum purchase price adds the usable down payment while accounting for minimum-down-payment rules and any estimated default-insurance premium added to the loan. The CMHC and down payment calculator provides a more detailed insurance breakdown. All figures remain planning estimates subject to lender criteria.
Does CMHC insurance increase how much I can borrow?
Mortgage default insurance may allow an eligible purchase with less than 20% down, but the premium is normally added to the mortgage and uses part of the borrowing capacity. Homes priced at $1.5 million or more require at least 20% down under the calculator's current rules. Review the CMHC insurance estimate and remember that insurer and lender approval criteria still apply.
What mortgage stress-test rate does this calculator use?
The configured qualifying rate is the greater of the contract rate plus two percentage points or a 5.25% floor. That rate is used for the affordability estimate, not promised as the mortgage rate you will receive. Stress-test treatment and qualification depend on the transaction and lender criteria, so the calculated maximum should be treated as an educational estimate rather than a pre-approval.
