Warnings to note

  • Gross income is before tax and deductions, so it is not the same as take-home pay.
  • Lender criteria vary. This estimate is not mortgage approval or borrowing advice.

General estimate only

This calculator provides general planning estimates only. It is not financial, tax, legal, accounting or mortgage advice. It does not assess credit, lender rules, approval, grants, tax effects or local borrowing requirements.

How this mortgage affordability calculator works

The calculator starts with gross monthly income, subtracts existing monthly debt payments from the selected total debt limit, then compares that with the selected housing-cost limit. Recurring housing costs reduce the amount left for an estimated mortgage payment.

Income, debts and housing-cost limits

The housing-cost limit is the share of gross monthly income used for mortgage and recurring housing costs. The total debt limit includes those housing costs plus existing monthly debts. These are user-entered planning limits, not lender rules.

What debt-to-income means in plain English

Debt-to-income compares monthly debt payments with gross monthly income. In this tool, the total debt ratio includes estimated housing costs and existing monthly debts, so higher existing debt leaves less room in the estimate.

Why deposit and loan-to-value matter

The usable deposit is added to the estimated affordable loan amount. A maximum loan-to-value assumption can reduce the estimated property price if the deposit is small relative to the loan size.

What this calculator does not include

This calculator does not provide mortgage approval, credit assessment, local borrowing rules, grant eligibility, tax advice, legal advice or a promise that a home is affordable. It is a general estimate based only on the assumptions entered.

Key terms and assumptions

  • Gross income: Income is entered before tax and deductions. It is not the same as take-home pay.
  • Housing-cost limit: The selected housing-cost limit is treated as a planning assumption, not a lender rule.
  • Total debt limit: Existing monthly debts reduce the estimated monthly amount available for housing costs.
  • Recurring housing costs: Property taxes or rates, insurance, shared-property fees, mortgage insurance and other costs reduce the estimated mortgage payment budget.
  • Loan-to-value: The maximum loan-to-value field can cap the property price estimate when the usable deposit is low.
  • Region settings: Region settings change labels, defaults and currency formatting only. They do not convert exchange rates or create country-specific results.
  • General estimate: The result is not mortgage approval and does not include credit assessment, lender rules, grants, tax or legal rules.
