Estimate a property-price ceiling and expose which entered income, debt, housing-cost, and cash constraint drives the result.
It keeps the property value, balance, cash amounts, rate convention, payment timing, and comparison horizon visible so the result can be checked against an actual quote, statement, budget, or contract.
Calculation structure
Follow the money through time
Affordable housing cost is the lower of the entered housing-income limit and total-debt-income limit, less other housing costs; the mortgage is the present value of that payment.

Read the estimate correctly
Use the result with its assumptions
Enter your own affordability ratios instead of relying on a country or lender default.
This is a budget scenario, not lender qualification or an approval estimate. Ratios are visitor-entered because lending rules differ; use Candidate Home Affordability Checker for one actual property and cash-reserve test.

Calculation method
Calculation method
Affordable housing cost is the lower of the entered housing-income limit and total-debt-income limit, less other housing costs; the mortgage is the present value of that payment.
The calculation retains full floating-point precision internally and rounds only for display. Amortization advances one payment period at a time so principal, interest, extra payments, and the final payment remain explicit.

Estimate, not an offer
Results model only the entered values. A lender may use different day counts, payment timing, fees, rounding, qualification rules, or contractual allocation.
International scope
No currency, country, tax system, insurance rule, mortgage program, or lender policy is assumed. Location-dependent amounts must be entered explicitly.
Calculator-specific assumptions
This is a budget scenario, not lender qualification or an approval estimate. Ratios are visitor-entered because lending rules differ; use Candidate Home Affordability Checker for one actual property and cash-reserve test.
