Estimate the qualifying rate and debt-service ratios for a Canadian mortgage purchase, renewal, or lender switch. The calculator uses the higher of the contract rate plus 2% or the applicable minimum qualifying rate, then compares housing costs and debts with income. It is an educational estimate, not a lender approval or a substitute for current underwriting.
This calculator sends you to the interactive stress-test inputs, where you enter the mortgage amount, contract rate, amortization, income, housing costs and other debts. It compares the qualifying payment at the higher of the mortgage contract rate plus 2% or the applicable minimum qualifying rate, then estimates GDS and TDS. Results are estimates, not an approval.

Renewals with the same lender normally do not require a new stress test. For an uninsured straight switch between federally regulated lenders, OSFI no longer prescribes the minimum qualifying rate, but the new lender still applies its own underwriting. Changes to the loan amount or amortization can alter treatment. Confirm current requirements before relying on an estimate.
Review the current OSFI minimum qualifying rate, OSFI's uninsured straight-switch guidance, and the Financial Consumer Agency of Canada mortgage guidance. Rules and lender policies can change, so check the sources again when applying.
