How it works
Methodology & formulas
This calculator is transparent by design. Review the steps and formulas so you can trust the estimate and adjust assumptions when your dashboard differs.
Calculation steps
- 1Convert annual gross income to monthly income.
- 2Build a monthly housing budget from the selected ratio limits and other debts.
- 3Solve for the highest home price whose qualifying payment and price-based housing costs fit that budget.
- 4Apply Canadian CMHC or U.S. PMI planning assumptions, then show contract and qualifying payments separately.
Formulas
- Monthly income = annual gross income ÷ 12
- Canada housing budget = min(income × GDS, income × TDS − other debts)
- U.S. housing budget = min(income × front-end DTI, income × back-end DTI − other debts)
- Qualifying rate = Canada max(contract + spread, floor); U.S. contract + spread
- Housing ratio = qualifying housing costs ÷ monthly gross income × 100
Important assumptions
- Canada qualifying rate defaults to max(contract rate + 2%, 5.25%). GDS defaults to 39% and TDS to 44%, all editable.
- U.S. front-end and back-end DTI values are lender-guidance planning assumptions. They are not universal legal or federal limits.
- The U.S. scenario rate equals the contract rate plus the editable U.S. scenario-rate spread; it is a comparison assumption, not a federal qualification rule.
- Property tax is modeled as an annual percentage of the estimated price. Heating, insurance, and condo or HOA costs are monthly inputs.
- Canadian condo fees use a 50% ratio component. U.S. HOA uses the full entered amount. Conventional U.S. PMI is estimated above 80% LTV.
- The result does not account for credit score, income history, lender overlays, appraisal, program eligibility, taxes, or live rates. It is not an approval decision.

Use the current terms
These Canadian and U.S. government references are starting points for mortgage insurance, home-buying education, and selected taxes. They do not validate every default or determine eligibility. Rates, fees, taxes, rebates, qualifying rules, and lender criteria change by jurisdiction and borrower. Use the editable assumptions, then confirm current terms with a licensed mortgage broker or lender.
Defaults are editable estimates. Match them to your current account, provider statement, official authority, lender, or adviser before making a pricing or investment decision.
