Can I afford a £1 million house on a £120k salary in the UK?
A £1m property on a £120k salary (8.3×) sits firmly in private bank and specialist HNW lender territory. At this income level — above the personal allowance taper — your take-home pay is limited by a 60% effective marginal tax rate on £100k–£125k. This makes the monthly repayment as a proportion of take-home even more acute than the raw multiple suggests. That said, buyers at £120k with strong assets and pension wealth frequently do purchase at this level through the right channels.
This is significantly above standard lending criteria. Consider a lower price or increasing your salary.

Results update as you type
You are in a strong affordability position compared to the UK average
Your income and disposable income are both above typical levels for UK buyers, giving you solid flexibility on housing, rent, and car choices.
Safe monthly disposable income
After expenses and debt, you have around £8,100 left each month — with a 10% buffer built in for unexpected costs. This is comfortable for most people at this income level.
Home you could realistically afford
Around £578k is a realistic target based on your salary, savings, and outgoings. Outside London, this budget typically goes further.
Most UK buyers with a similar income typically purchase between £508k and £647k
Recommended rent budget
Up to £3,500/month keeps your finances healthy based on the 30–35% income rule. Anything above this may start to feel like a stretch.
Car finance calculator
Most cars in the UK are purchased using finance (PCP or HP), where buyers pay a deposit and a fixed monthly cost. This estimate gives a realistic guide based on typical finance rates (~8% APR).
How much you can comfortably pay each month
£200–£350/month is a sensible range for most UK buyers. This is what many people on a typical salary comfortably spend on a car.
Most UK car buyers use PCP or HP finance — affordability is based on monthly payments, not total price.
Outside London, this budget typically goes further. In London and higher-cost areas, affordability is usually 15–25% lower than these figures suggest.

What the numbers mean for you
Standard lending multiple: Most UK mortgage lenders will lend between 4 and 4.5 times your annual salary. On a salary of £120k, that translates to a maximum mortgage of roughly £480k to £540k.
The £1.00m property: This home is 8.3 times your annual salary. This exceeds the standard lending multiple. You will need either a significant deposit or to explore specialist lending options.
Deposit strategy: A deposit of 25–40% is typically required for properties at this price-to-income ratio.
Which lenders to approach: Private banks and high-net-worth mortgage specialists are likely your best route at this borrowing level.
Other factors that affect lending: Credit score, employment type, existing debts, number of dependants, and monthly expenditure all influence what you can borrow. Speaking to an independent mortgage broker gives you the clearest picture of your real options.

A realistic buyer scenario
Anna, 48 — senior partner at a law firm, West London
Anna earns £120,000 and has built up £350,000 in savings over 20 years of senior roles. She is buying a four-bedroom house in Chiswick, West London at £1,000,000 as a long-term family home. Her pension pot stands at £480,000 and she has no outstanding mortgage or debt.
Anna's £350,000 deposit (35%) leaves a £650,000 mortgage — 5.42× her salary. Her effective take-home on £120k is around £6,400/month due to the personal allowance taper. A private bank, weighing her pension wealth and spotless credit history, approves the full £650,000 at a preferential rate of 3.9% for a 20-year term. Monthly repayments of £3,850 represent 60% of her take-home — tight, but manageable given no other financial commitments.
