How much do I need to earn to buy a house?
The salary behind a given house price — once you fold in your deposit, the lender’s income multiple, and the costs people forget until completion day.
It works backwards from the house, not the salary. For a typical first-time buyer home of around £228,000 with a 10% deposit, you’re borrowing roughly £205,000 — which at the usual 4.5× income multiple needs a salary of about £46,000, or comfortably less split across two earners. Change the deposit or the price and that figure moves a lot, which is exactly why there’s no single answer.
The quick answer
Your required salary is the loan you need divided by the lender’s income multiple — usually 4.5×. For a £200,000 home with a 10% deposit, the £180,000 loan needs an income of around £40,000. For a £250,000 home it’s about £50,000, and for £300,000 roughly £60,000. A joint application combines both incomes, so the figure per person is far lower for couples.
The calculation is simpler than it looks
Strip away the noise and there are just three numbers: the price of the house, the deposit you bring, and the multiple of income a lender will offer. Subtract the deposit from the price to get the loan you need. Divide that loan by 4.5 — the multiple most UK lenders use — and you have the rough salary required.
So a £250,000 home with a £25,000 deposit (10%) means a £225,000 loan, which at 4.5× needs an income of around £50,000. That’s it. Everything else — credit history, debts, employment type — adjusts that figure at the edges, but the spine of the answer is those three numbers and one division.
Salary needed by house price
This table assumes a 10% deposit and the standard 4.5× multiple. Use it to find the rough income for the price bracket you’re aiming at — and remember that for couples, this is the combined figure.
| House price | 10% deposit | Loan needed | Salary (at 4.5×) |
|---|---|---|---|
| £150,000 | £15,000 | £135,000 | £30,000 |
| £200,000 | £20,000 | £180,000 | £40,000 |
| £228,000 (typical FTB) | £22,800 | £205,200 | £46,000 |
| £250,000 | £25,000 | £225,000 | £50,000 |
| £285,000 (UK average) | £28,500 | £256,500 | £57,000 |
| £300,000 | £30,000 | £270,000 | £60,000 |
Notice how the typical first-time buyer property — around £228,000 — needs a single income near the mid-£40,000s, comfortably above the UK average salary. That gap is precisely why so many first homes are bought jointly: split £46,000 across two people and each only needs to earn around £23,000.
Your deposit does heavy lifting
The deposit isn’t just an entry ticket — it directly lowers the salary you need, because every pound of deposit is a pound you don’t have to borrow. On a £250,000 home, a 10% deposit needs around £50,000 of income; push the deposit to 20% and the loan drops to £200,000, cutting the required salary to roughly £44,000.
The catch worth knowing: most first-time buyers put down far more than the 5% minimum. The average first-time deposit in England is close to £64,000 — roughly a fifth of the price — which means real buyers usually need a lower salary than the 10%-deposit table suggests. A bigger deposit also unlocks better mortgage rates, so it pulls two levers at once: smaller loan, cheaper borrowing.
What else lenders weigh
Existing debts
Car finance, loans and credit cards reduce the income a lender treats as available, effectively raising the salary you’d need for the same house.
Joint vs single
Lenders combine two incomes, so couples reach a given price on much lower individual salaries — the single biggest lever for most buyers.
The forgotten costs
Stamp duty, legal fees, surveys and moving all sit on top of the deposit. Budget for them separately, or they eat into your deposit.
Employment type
Self-employed buyers borrow on the same multiples but need two to three years of accounts to prove the income behind them.
One quiet bit of good news worth knowing: first-time buyers pay no stamp duty up to £300,000, so on a typical first home that particular upfront cost falls away entirely — leaving the deposit and fees as the real hurdles.
A worked example
Couple buying a £250,000 first home, 10% deposit
Two people each earning around £25,000 can reach a £250,000 home — a figure that sounds out of reach on a single salary but is very ordinary as a couple. Stamp duty here is £0 thanks to first-time buyer relief.
The pattern holds throughout: the salary you need is a simple function of price, deposit and multiple — but your salary is the one the lender actually approves after the affordability test. The quickest way to your real figure is to run your own income through the numbers rather than read an average.
Common questions
What salary do I need to buy a £200,000 house?
With a 10% deposit of £20,000, you’d be borrowing £180,000, which needs an income of around £40,000 at the standard 4.5 times multiple. A larger deposit lowers this — a 20% deposit cuts the loan to £160,000 and the salary needed to roughly £36,000. For couples, the figure is the combined income, so each person needs much less.
How much do I need to earn to buy an average UK house?
The average UK house price is around £285,000. With a 10% deposit, the £256,500 loan needs an income of about £57,000 at 4.5 times. The typical first-time buyer property is cheaper — around £228,000 — needing closer to £46,000. Both fall comfortably within reach for two earners on average salaries.
Can I buy a house on a single income?
Yes, but the salary required is higher than for a couple, because there’s only one income to apply the multiple to. A single buyer on £40,000 with a 10% deposit could target a home around £200,000. Buying jointly roughly doubles the reachable price for the same individual salary, which is why most first homes are bought by couples.
Does a bigger deposit reduce the salary I need?
Yes, directly. Every pound of deposit is a pound you don’t borrow, so a larger deposit shrinks the loan and therefore the income required. On a £250,000 home, moving from a 10% to a 20% deposit drops the loan from £225,000 to £200,000, lowering the salary needed from around £50,000 to about £44,000 — and usually unlocking better rates too.
How is the salary figure actually calculated?
Take the house price, subtract your deposit to get the loan, then divide the loan by the lender’s income multiple (usually 4.5). For a £300,000 home with a £30,000 deposit, the £270,000 loan divided by 4.5 gives a required income of £60,000. It’s a starting point; the lender’s full affordability assessment can adjust it based on your debts and outgoings.
What costs come on top of the deposit?
Stamp duty (though first-time buyers pay nothing up to £300,000), legal and conveyancing fees, a mortgage valuation or survey, and moving costs. Together these typically add a few thousand pounds on top of the deposit, so budget for them separately rather than assuming the deposit covers everything.
Do these figures apply across the whole UK?
The calculation is the same everywhere, but prices vary dramatically. London averages around £510,000, pushing the salary needed far higher, while parts of the North and Scotland sit well below the UK average. The method — loan divided by multiple — holds; only the house price you plug in changes.

How we put this together
The required salary is calculated as the loan (house price minus deposit) divided by the lender’s income multiple, using the common 4.5× cap. House prices reflect recent UK averages: around £285,000 UK-wide and £228,000 for a typical first-time buyer property, per Land Registry, ONS, UK Finance and Nationwide data.
Deposit figures use the average English first-time buyer deposit of roughly £63,855 (UK Finance). All salary figures are illustrative starting points; a lender’s full affordability assessment, your debts and prevailing rates determine the actual offer.
