How much can you borrow on a £45,000 salary?

Most lenders work to an income multiple of around 4 to 4.5 times your salary. On £45,000 that points to roughly £180,000 to £202,500 of borrowing. Some lenders go higher for strong profiles, and some lower if your commitments are high, so treat this as a starting point rather than a promise.

To buy a home around £225,000 with a 10 percent deposit, you would aim for about £22,500 saved. A larger deposit usually unlocks better rates and more lender options, which is why your deposit is the single biggest driver of your Mortgage Ready Score.

Turning £45,000 of salary into a monthly payment

A borrowing range only becomes real when you translate it into a monthly payment. Using the standard formula for a 25 year repayment mortgage, here is what a £180,000 loan (4 times your income) and a £202,500 loan (4.5 times) would cost each month at three illustrative rates. Treat every figure as a worked example rather than a quote: your actual rate depends on your loan to value, your credit file and whatever deals exist on the day you apply.

The gap is the lesson here. Between the cheapest and dearest illustration, the bigger loan moves by £236 a month, month after month for 25 years. On £45,000 a year, few single decisions are worth as much as qualifying for a better rate, which is mostly a function of deposit size and credit history.

How far £45,000 stretches at each deposit level

Take the top of the typical range, a £202,500 loan, and place three different deposits beside it. The purchase price it supports shifts with every percentage point you save:

Each step up the ladder needs more cash but buys two advantages at once: a higher price ceiling and a lower loan to value, and the second is what usually earns the cheaper rate. Keep a separate buffer for legal fees, the survey and moving day, so the deposit pot is not raided at the finish line.

What a second income does to the £45,000 picture

Joint applications are assessed on combined income, so the arithmetic changes quickly. If you and a partner both earned £45,000, a combined income of £90,000 points to roughly £360,000 to £405,000 of borrowing. Even a second income of half that, £22,500, lifts the household to £67,500 and a typical range of £270,000 to £303,750. Both credit files count on a joint application, so the weaker file tends to shape the deal you are offered.

What matters most in the £45,000 range

In this middle band the gap between the 4x and 4.5x multiples is now £22,500 of borrowing, which is often the difference between price brackets. Which end of the range you land at is decided by the quality of your file: clean credit, modest commitments and a solid deposit push you toward the top of the range, while heavy monthly outgoings drag the offer down toward the bottom or below it.

The deposit ladder above also becomes a genuine strategic choice here. Stepping from a 10 to a 15 percent deposit means finding roughly £13,200 more in cash, but it reduces your loan to value and typically opens cheaper rates, which compounds every month of a 25 year term. Many buyers in this band face the classic trade off between overpaying existing debt and growing the deposit. There is no universal answer, but the arithmetic favours clearing expensive monthly commitments first when they are restricting how much you can borrow, then redirecting that payment into savings. Your Mortgage Ready Score shows which of the two is holding you back more.

What actually decides your figure

• Your deposit size against the property price.
• Monthly commitments such as loans, cards and car finance.
• Your credit history and how you manage existing accounts.
• Employment type and how long you have been in your role.
