Salary Needed for a Mortgage 2026/27
The household income lenders want for a target house price and deposit, at 4.0x, 4.5x and 5.0x loan-to-income, based on the Bank of England LTI flow limit.

How lenders decide how much you can borrow
UK mortgage lenders use a loan-to-income (LTI) multiplier to set their maximum offer. Most lenders operate in the 4.0x to 4.5x range for standard applications; some specialist lenders or professional schemes stretch to 5.0x or 5.5x for qualifying applicants.
This calculator reverses the question: instead of asking “how much can I borrow on my salary?”, it asks “what salary do I need for a target property?” See the mortgage affordability calculator for the forward direction.
The 4.5x portfolio cap - what it means for you
The Bank of England’s Financial Policy Committee (FPC) limits the share of new residential mortgage lending at a loan-to-income ratio of 4.5 or more to 15%. In its July 2025 Financial Stability Report the FPC recommended changing how this is applied, so that an individual lender can lend more than 15% of its flow at 4.5x or above provided lending across the market as a whole stays within the 15% limit. It is a limit on lenders - not a statutory cap on any individual borrower.
In practice it means:
- Most borrowers at 4.5x or below face a straightforward underwriting process.
- Borrowers seeking 4.5x or more need strong income evidence, a low debt-to-income ratio, and a lender with room for high loan-to-income lending.
- How much room a lender has now varies by lender, because individual lenders can exceed 15% while the market-wide share stays within it.

Deposit size matters
The loan you need is property price minus deposit. A larger deposit directly reduces the salary requirement:
| Property price | Deposit | Loan | Salary at 4.5x |
|---|---|---|---|
| £200,000 | £20,000 (10%) | £180,000 | £40,000 |
| £200,000 | £40,000 (20%) | £160,000 | £35,556 |
| £300,000 | £30,000 (10%) | £270,000 | £60,000 |
| £300,000 | £60,000 (20%) | £240,000 | £53,333 |
A 10% deposit (90% LTV) also typically attracts a higher mortgage rate than a 25% deposit (75% LTV), so the monthly cost gap is wider than the income requirement alone suggests.
Cautious, standard, and stretch scenarios
The calculator shows three scenarios:
- Cautious 4.0x - the typical ceiling for joint applications where one income is variable, or for borrowers with existing credit commitments.
- Standard 4.5x - the threshold in the FPC’s loan-to-income flow limit.
- Stretch 5.0x - available at selected lenders (e.g. professional mortgage schemes for doctors, lawyers, and accountants) where income trajectory is strong.
Your actual offer will also depend on credit history, existing debt, childcare commitments, and the lender’s internal affordability model.

Frequently asked questions
What salary do I need for a £250,000 mortgage?
At the typical 4.5x loan-to-income multiple, you need roughly £50,000 household income for a £225,000 loan (£250,000 property with a £25,000 deposit). At a cautious 4.0x you would need £56,250; at a stretch 5.0x some lenders may accept £45,000. 4.5x is the threshold in the Bank of England's loan-to-income flow limit, which caps how much lending sits at or above it across the market - it is not a per-borrower limit or a guarantee.
What is the 4.5x income cap for mortgages?
The Bank of England's Financial Policy Committee limits the share of new residential mortgage lending at a loan-to-income ratio of 4.5 or more to 15%. Since its July 2025 Financial Stability Report, an individual lender may go above 15% as long as lending across the market stays within the 15% limit. It is a limit on lenders, not a per-borrower rule, so a borrower can be offered 4.5x or more if a lender has room and the affordability checks pass.
Does this calculator work for joint applications?
Yes - the calculator asks only for the property price and deposit, and the income it returns is the total gross annual income the applicants need between them. Compare it with your combined income. How each lender treats a second income, bonus or variable pay varies, so check with the lender or a broker.
How does the deposit size affect the salary I need?
A larger deposit reduces the loan required and therefore the income the lender needs to see. For example, a 20% deposit (£50,000) on a £250,000 property leaves a £200,000 loan - needing roughly £44,444 at 4.5x rather than £50,000 for a 10% deposit. Use the calculator above to model different deposit scenarios.
