The stress test evaluates whether you could afford payments at a qualifying rate above your contract rate. It is a qualification calculation, not the rate you necessarily pay.
Two rates, two jobs
Banks generally use the higher of 5.25% or your contract rate plus two percentage points when a stress test applies. At a contract rate of 4.50%, that means a qualifying rate of 6.50%.
Income and debts matter together
Housing costs include mortgage payments, property taxes, heating and part of condo fees. Other debt commitments also affect qualification. Common planning guidelines are 39% gross debt service and 44% total debt service; lender assessments can differ.
A calculator is a planning tool
An affordability estimate cannot check credit, verify income, assess a property or replace underwriting. It is useful for seeing how a larger down payment, lower debt or different purchase price could change the picture.
Renewals and refinancing are different
Some eligible renewal switches receive different stress-test treatment. Refinancing or accessing additional equity may trigger qualification requirements. Ask which rules apply to your specific transaction rather than assuming every switch is exempt.
Separate qualification from comfort
A qualifying calculation is a lender assessment, not a complete household budget. Add childcare, transportation, savings and other commitments that matter to you. A lower purchase price, reduced debts or a larger reserve may make a plan more resilient even when the lender would permit more borrowing.
