Find out how much you could borrow, what your monthly payments might look like, and how much property you could realistically buy — all based on your income and deposit.
Lenders typically lend 4× to 5× your annual income. We show all three scenarios so you can see the realistic range.
Your deposit is added to each borrowing scenario to show the maximum property value you could afford.
We calculate a repayment mortgage payment at the rate and term you enter, so you can check affordability month by month.
Estimates based on income multiples used by mainstream UK lenders
When you apply for a mortgage, lenders assess whether you can afford the repayments — not just now, but if interest rates rise. This is why their offer may differ from the figures in this calculator.
Most mainstream lenders use income multiples as an initial filter. A lender offering 4.5× income would lend up to £225,000 on a single £50,000 salary. Joint applications combine both salaries, so a couple each earning £40,000 could potentially borrow up to £360,000 at 4.5×.
Some specialist lenders and high-street banks offer 5× income for strong applicants — typically those with large deposits, stable professional employment, or first-time buyers purchasing under the mortgage guarantee scheme.

Use our Help to Buy Calculator to understand what your equity loan interest charges will be, then factor them into this affordability estimate.
