Will a lender offer me 4.5 times my income?

Not necessarily. 4.5 times income is the regulatory description of a high loan-to-income mortgage. Lenders also look at spending, dependants, the deposit, the property, and your credit history.

Whose income can I include?

The second box is for a joint applicant's gross annual income. Do not include overtime, bonus, or benefits unless you know a lender will count them. This calculator treats whatever you type as gross income.

What should I put in credit commitments?

Monthly payments you already make on loans, cards, and other credit. Do not include everyday bills. The calculator annualises that figure and takes it off income before applying 4.5 times. A lender's own sum will be more detailed.

4.5 times income is the high loan-to-income threshold used by the Bank of England and the FCA. It is not an offer.

How this is worked out

4.5 times gross income is the line the Bank of England and the regulators use to describe a high loan-to-income mortgage. From 28 October 2026 the old rule that capped each lender's high loan-to-income lending at 15% was replaced by a limit on the market as a whole. A lender can still say no well below 4.5 times, and some will lend more.

This page shows two numbers. The first is 4.5 times your gross income, or your joint gross income. The second subtracts a year of the credit commitments you type in, then multiplies what is left by 4.5. That second step is a plain illustration, not the expenditure test in the FCA's MCOB rules.

The stressed payment adds 3 percentage points to the rate you enter. The Financial Policy Committee's formal stress test was withdrawn on 1 August 2022. Lenders still have to think about future rate rises. The stressed figure is there so you can see the monthly cost if the rate is higher. It is not a decision in principle.
