This calculator works two ways: find your maximum mortgage based on your income, or your required income based on a target mortgage amount — switch between them using the tabs above.
Both directions use the same stress-test rate (the greater of your rate + 2% or 5.25%) and your GDS/TDS ratios to size the result.
GDS and TDS targets are editable, defaulting to 32%/40% — adjust them to match your own lending scenario.
Home expenses (property tax, condo fees, heat) and monthly debts factor into both calculations the same way.
Results are for planning purposes only — your lender will confirm your actual approval amount.
