How Lenders Calculate Your Borrowing on £45,000
UK mortgage lenders typically use an income multiple of 4 to 4.5 times your gross annual salary. On £45,000, this means:
- Conservative (4×): £180,000
- Standard (4.5×): £202,500
Some specialist lenders offer up to 5.5× income for professionals (doctors, solicitors, accountants) or borrowers with very low outgoings. However, most high-street lenders cap at 4.5×.
Lenders also run an affordability stress test at a higher rate (typically base rate + 3–4%) to ensure you could still afford payments if rates rise. Monthly commitments like car finance, credit cards, and childcare reduce the amount available.
