It estimates the household salary needed for a target mortgage using an adjustable income multiple. It is a planning tool rather than a lending decision, so the result should be checked against the lender’s affordability policy and your own monthly commitments.

Income multiples are only a starting point. Lenders also assess committed spending, age, credit history, income type, deposit size and how the payment looks at a higher stress rate.
This page helps you work backwards from a target mortgage amount to the salary that a lender might typically want to see. It is useful when you already know the house price or borrowing target and want to see whether the job move or household income is enough.
It estimates the household salary needed for a target mortgage using an adjustable income multiple. It is a planning tool rather than a lending decision, so the result should be checked against the lender’s affordability policy and your own monthly commitments.
A smaller deposit usually pushes the required salary up because more of the purchase price must be financed. A bigger deposit, a better rate or a longer term can lower the salary needed, but the lender can still cap borrowing if the affordability check is tight.
- Income multiples, stress rates, credit profiles, deposit size and the type of income being used all affect the outcome.
- Two households with the same headline salary can still get different answers because commitments and lender policy matter too.
Where this sits in the cluster
This page sits between affordability and the actual mortgage payment. If the salary target feels too high, check the affordability calculator first, then compare the repayment page and overpayment page to see whether the numbers become more realistic with a different term, deposit or rate.

Why two users can see different results
Why the result can differ
Different tax codes, payroll periods, Scottish bands, pension methods or lender assumptions can change the outcome.
One-off bonuses, pay frequency, overpayments, allowances and reliefs can move the result away from a simple annual estimate.
Where a rule depends on eligibility or legal status, this page shows an estimate and links to official guidance.
This section is intentionally repeated on key tools so the explanation stays near the result instead of being hidden in a separate policy page.

Is 4.5 times salary guaranteed?

Can two incomes be used?
Often yes, subject to each lender’s treatment of income and commitments.
Does deposit size matter?
Yes. A larger deposit often reduces the salary needed for the same borrowing target.
