Calculator guide
Use affordability as a guardrail
An affordability estimate starts with gross income and debt ratios, then subtracts property tax, heating or insurance assumptions, condo fees, and other debt before converting the remaining payment capacity into a mortgage amount.
Approval and affordability are different. Keep a cash buffer and test a higher rate, because a lender's maximum is not a recommendation for a resilient household budget.
What the price ceiling means
The result combines the mortgage supported by the entered payment cap with cash available for the down payment. It is a planning ceiling, not a loan approval.
Compare a smaller purchase price and keep room for closing costs, repairs, income changes, and rate changes.
Questions answered
Frequently asked questions
Does this calculator preapprove a mortgage?
No. A lender verifies income, debt, credit, property, down payment, insurance, and its own underwriting rules.
Should all available cash become the down payment?
Usually not. Closing costs, repairs, moving expenses, and emergencies need liquid cash.
Why stress a higher rate?
It shows whether the budget remains workable if the contract rate or future renewal payment rises.

Use the estimate well
What this calculator can and cannot tell you
It can model transparent assumptions, compare scenarios, and expose tradeoffs. It cannot approve a loan, quote a lender, predict markets, interpret your contract, or replace licensed advice.
Try a range
Run the base case, a higher rate, a lower home value, and a cash-buffer case.
Check the contract
Confirm compounding, prepayment, fees, insurance, dates, and lender rounding.
Keep liquidity
A feasible payment is not the same as a resilient household budget.
