Use this free mortgage stress test calculator for Canada to estimate how much you may be able to borrow when qualifying at a higher mortgage interest rate.
Enter your annual income, monthly debt payments, actual mortgage rate, stress test floor, buffer, and amortization period to estimate your borrowing capacity in Canadian dollars (CAD).
Estimate Your Mortgage Qualification Under the Stress Test
Canada’s mortgage stress test checks whether borrowers can afford mortgage payments at a qualifying rate higher than their actual contract rate in many situations.
This calculator uses the higher of your entered minimum qualifying rate and your actual rate plus the stress buffer to estimate how the higher rate affects your borrowing capacity.
Understand How Income and Debt Affect Your Result
Your income helps determine how much you may be able to afford, while existing debt payments reduce the amount available for housing costs. This calculator uses a simplified 44% total debt service (TDS) limit to estimate the monthly payment available for the mortgage.
Actual lender assessments may also consider housing costs and other obligations. Try our Canadian mortgage affordability calculator for another borrowing estimate.
See How the Qualifying Rate Changes Your Borrowing Power
A higher qualifying interest rate increases the payment used in the affordability calculation, which generally reduces the mortgage amount you can support.
Even if your offered rate is relatively low, the qualifying rate may be higher. You can also explore our Canadian mortgage calculator to compare mortgage scenarios.
Compare Mortgage Amortization Periods
Your amortization period affects the payment calculation and estimated borrowing capacity. A longer amortization generally lowers the payment required for a given loan amount, although it can increase total interest over time.
The calculator lets you compare 25- and 30-year periods, but eligibility for a 30-year amortization depends on the mortgage type and applicable rules. You can also use our Canadian mortgage payment calculator to estimate payments.
What Your Stress Test Result Means
The result is an estimate, not a mortgage approval or guarantee of eligibility. Lenders may consider credit history, down payment, property taxes, heating costs, condominium fees, mortgage insurance, and other criteria.
Before making a purchase decision, confirm the qualifying rate, affordability requirements, and available mortgage terms with a Canadian lender or qualified mortgage professional.
