Affordability calculator

Start from income, not wishful pricing.

This calculator works backwards from income, debt, and recurring housing costs so the ceiling reflects how lenders qualify mortgages, not just what feels manageable at first glance.

Uses the higher of 5.25% or contract rate plus 2%.
Applies 39% GDS and 44% TDS guardrails.
Down payment, condo fees, and heating costs all push the result materially.
Inputs
Income, debt, and housing costs
Qualification is based on editable example rates, not live market pricing. Defaults last updated April 18, 2026.

Assumptions
How this version behaves
The inputs are flexible, but the rules are intentionally explicit so the outputs stay interpretable.
The calculator is a planning tool and not a lender pre-approval.
Property taxes, heating, and 50% of condo fees feed into qualification math.
The result assumes monthly mortgage payments for qualification even if you later choose a different payment cadence.
