Quick answer
Using the transparent planning range on WizeBudget, a £75,000 gross salary produces an illustrative borrowing range of £300,000 to £375,000. The midpoint, 4.5× income, is £337,500. With a £20,000 deposit, that midpoint property budget would be £357,500.
This is not a mortgage offer. A lender can offer less or more after assessing commitments, credit, dependants, employment, property, deposit, term and its future-rate affordability test.

What changes the amount you could actually borrow?
Mortgage income multiples are a screening tool, not the whole decision. Your actual maximum can change with monthly commitments, childcare, credit history, deposit size, property type, the term you choose and the lender’s affordability model. The FCA requires lenders to consider likely future interest-rate rises, but each lender determines its own approach.
