How lenders work out borrowing
Most lenders cap loans at around 4.5 times income, and some go to 5 to 5.5 times for higher earners or certain professions. They then run a detailed affordability check on your income, spending, credit commitments and a stressed interest rate.
Why the result is a range
The lower figure reflects mainstream lending; the higher figure shows what may be possible with lenders offering enhanced multiples. Your real maximum depends on the lender's model.
Frequently asked questions
How much can I borrow on £100,000 salary?
Typically around £450,000 at 4.5 times income, and potentially up to around £550,000 with lenders offering 5.5 times for higher earners, subject to affordability and commitments.
Do lenders count bonus and rental income?
Many do, often at 50% to 100% depending on how regular it is and how long you've received it. This calculator counts other income at 50% to stay cautious.
Does a mortgage in principle affect my credit score?
Many lenders use a soft search for a mortgage in principle, which doesn't affect your score. Some use a hard search, so it's worth asking first.
Important: Your home may be repossessed if you do not keep up repayments on your mortgage. There may be a fee for mortgage advice: up to 1% of the loan, typically £500.
