What Is Mortgage Affordability?

Mortgage affordability is the lender’s view of how much you may be able to borrow.

It is not based only on income. Lenders may also review spending, debts, dependants, credit history, property type and mortgage term.

A simple income multiple can be useful at the start. However, a full lender assessment is usually more detailed.

Mortgage Affordability Calculator

Estimate how much you could borrow based on income. Typical values are pre-filled — just adjust what you know.

Leave as "Standard" if you're unsure — your adviser will confirm what a lender will offer you.

Leave as 0 if you're not putting down a deposit yet.

Loans, car finance, credit cards etc. Leave as 0 if you don't have any.

This calculator gives an illustrative estimate only, based on a simple income-multiple methodology. It does not represent full affordability underwriting, which also considers credit history, dependants and detailed expenditure — actual borrowing will vary by lender. Please speak to one of our advisers for a full affordability assessment.

Why Income Multiples Are Only a Starting Point

Many affordability estimates begin with an income multiple.

For example, a calculator may apply a standard multiple to household income. This helps create a quick planning figure.

However, lenders do not all use the same method. Some may lend more where income is strong and commitments are low. Others may lend less where the case carries more risk.

Your result may change because of:

  • Loan or credit card payments
  • Car finance
  • Childcare costs
  • Dependants
  • Credit history
  • Employment type
  • Retirement plans
  • Mortgage term
  • Deposit size
  • Loan-to-value
