UK affordability calculator

What UK lenders may offer — based on income multiples (4.0x–5.5x) and the FCA stress test — shown as a realistic range, not a single number.

What you might borrow

UK lenders mainly use income multiples, then stress-test affordability — so this is a realistic range, not a single quote.

Estimated property price range (loan + deposit)

£220,000£287,500

Likely maximum loan, by income multiple

Conservative (4.0×)
£180,000
Typical (4.5×)
£202,500
Enhanced (5.5×)
£247,500

Based on a total income of £45,000.

Lenders must also check you could afford repayments if rates rose — typically tested at your rate plus at least 1 percentage point (here: ~5.92%) for a minimum of 5 years, per FCA rule MCOB 11.6.18R. The exact stress methodology varies by lender — this is the regulatory floor, not a single number every lender uses identically. If your fixed deal itself runs 5+ years, this specific stress test doesn't apply to that contract.

Enhanced multiples (5.5x+) are typically only available above roughly £75,000 income — the figure shown is illustrative of what's possible at higher incomes, not a guarantee at your income level.

An estimate to help you plan — not financial advice, a mortgage offer, or a guarantee of what any lender will lend. Figures vary by lender and your full circumstances.
