HouseCheckup's affordability calculator estimates how much you could borrow based on your income, outgoings, and deposit. UK lenders typically offer 4–4.5x your annual salary, but affordability stress tests introduced by the FCA mean actual borrowing depends on your spending commitments too. Over 370,000 mortgages were approved in the UK in the last 12 months — use our calculator to see where you stand before approaching a lender.

Most UK lenders cap borrowing at 4–4.5 times your gross annual salary. A household earning £60,000 could typically borrow £240,000–£270,000. However, lenders also stress-test affordability at higher interest rates and factor in existing debts, childcare costs, and living expenses. HouseCheckup's calculator accounts for these variables.
A mortgage stress test checks whether you could still afford repayments if interest rates rose — typically by 3 percentage points above the lender's standard variable rate. This was introduced by the FCA to prevent borrowers overextending. HouseCheckup's affordability calculator applies stress testing so your estimate reflects real-world lender criteria.
Yes. Joint applicants can typically borrow 4–4.5 times their combined gross income. A couple earning £40,000 and £35,000 could borrow approximately £300,000–£337,500. Joint applications also allow both applicants' deposits and savings to be combined, improving the loan-to-value ratio.
