Find out exactly how much mortgage you can afford in the UK based on your income, deposit, stress test, and stamp duty costs. Includes income multiple tables, salary-based borrowing examples, and a comparison of affordability rules across the UK, USA, Canada, and Australia.
TL;DR: UK lenders use income multiples (typically 4–4.5x your salary), stress tests, and affordability checks on your existing commitments to determine your maximum mortgage. Your deposit size, stamp duty liability, and regional price differences all affect the final number.
The question how much mortgage can I afford UK sounds simple enough. But the number in your head and the number lenders will actually give you are rarely the same. In 2026, with the Bank of England base rate holding around 4.25% and property prices still elevated in most regions, the gap between what you want to borrow and what you can actually borrow is wider than many people expect.
UK lenders do not just look at your income, multiply it by four-and-a-half, and call it done. They run you through a stress test, check your existing commitments, factor in council tax and utility estimates, and then decide whether you can really afford the mortgage they are offering.
This guide covers exactly how UK lenders calculate your maximum mortgage, how much you need for a deposit, what stamp duty will cost, and how affordability rules compare in the USA, Canada, and Australia. By the end, you will know your real budget and exactly what you need to do to hit it.
How Much Can I Borrow Mortgage UK? The Income Multiple Explained
The foundation of UK mortgage lending is the income multiple. How much can I borrow mortgage UK depends primarily on your gross annual income, not your take-home pay, not your savings, not your potential rental income if you Airbnb your spare room. Your gross income.
The Standard 4.5× Rule
UK mortgage 4.5 times income is the standard across most high street lenders. If you earn £50,000, your maximum mortgage is roughly £225,000. Joint applicants get 4.5× their combined income, two earners on £40,000 and £30,000 can borrow up to £315,000 together.
| Scenario | Income | Multiple | Max Mortgage |
|---|---|---|---|
| Single earner | £50,000 | 4.5× | £225,000 |
| Single earner | £60,000 | 4.5× | £270,000 |
| Joint applicants | £85,000 | 4.5× | £382,500 |
| Joint applicants | £120,000 | 4.5× | £540,000 |
| High earner (select lenders) | £100,000+ | 5× | £500,000+ |
The 4.5x income mortgage maximum UK is not a hard legal cap, some lenders will go higher for certain professions. But for most borrowers, 4.5× is the ceiling.
How much mortgage can I get on £50,000 salary UK 2026: £225,000 at 4.5×. With a 10% deposit of £25,000, that means you are looking at properties around £250,000. Stamp duty is zero for a first-time buyer at that price, which helps.
How much mortgage can I get on £60,000 salary UK: £270,000 at 4.5×. With a 10% deposit (£30,000), you are looking at £300,000 properties. If you stretch to a 5% deposit, the deposit drops to £15,000 but your rate will be higher and the selection of deals narrower.

The Mortgage Affordability Stress Test Explained
Beyond the income multiple, the Bank of England mortgage stress test is the second big gatekeeper. This is the test that catches people off guard.
How the Stress Test Works
Lenders must check that you can still afford your mortgage if interest rates rise significantly. Here is the mortgage affordability stress test explained UK in plain language:
- Your lender takes their Standard Variable Rate (typically 7% to 8%)
- They add 3% on top (the mortgage stress test 3% addition Bank of England requires)
- They calculate what your monthly payment would be at that stress rate
- They check whether that payment is within an acceptable percentage of your monthly income
Example: Your lender's SVR is 7.5%. They test you at 10.5%. On a £270,000 mortgage over 25 years, your stress payment is roughly £2,540 per month. If your monthly income is £5,833 (£70,000 annual), that is 43.5%, on the edge of what most lenders will accept.
The mortgage stress test UK 2026 environment is stable, the BoE has not changed the 3% requirement since 2023, but higher base rates mean the absolute stress rate is higher than it was in 2021. A borrower who could borrow £270,000 at 4.5× income might only be offered £220,000 after the stress test.
Mortgage affordability after rate rise 2026 UK is tighter than in prior years, but lenders have adapted. Most now apply the stress test at the application stage rather than the offer stage, so what you see is what you get.
Mortgage affordability based on income UK and mortgage affordability stress test explained UK, the key takeaway is that your headline income multiple is the starting point, not the finish line. The stress test can knock 10% to 20% off your maximum.
Bank of England Base Rate Mortgage Impact 2026
The Bank of England base rate mortgage impact 2026 is straightforward: a higher base rate means a higher SVR, which means a higher stress rate, which means lower maximum borrowing. As rates stabilise, the impact is predictable, which is better than the volatility of 2022–2023.
How Much Deposit Do You Need?
Your deposit determines your Loan-to-Value ratio, which determines your rate. How much deposit do I need for £300,000 house UK breaks down like this:
| Deposit % | Deposit Amount | LTV | Typical Rate |
|---|---|---|---|
| 5% | £15,000 | 95% | 5.0%–5.5% |
| 10% | £30,000 | 90% | 4.5%–5.0% |
| 15% | £45,000 | 85% | 4.2%–4.7% |
| 20% | £60,000 | 80% | 4.0%–4.5% |
| 25% | £75,000 | 75% | 3.8%–4.2% |
First time buyer mortgage 5% deposit UK is achievable through the government-backed 95% mortgage scheme, which encourages lenders to offer high-LTV products. 5% deposit mortgage UK 2026 is still widely available, though rates sit higher than lower-LTV deals.

95% LTV mortgage UK products and 95% mortgage UK 2026 deals are available from most major lenders, but the stamp duty on £400,000 house UK and stamp duty on £500,000 house UK will add to your upfront costs as a mover or second-home buyer.
How much can I borrow with £25,000 deposit UK: At 10% down on a £250,000 property, you need a £225,000 mortgage, which requires roughly £50,000 income at 4.5×. At 5% down on a £500,000 property, you need a £475,000 mortgage and roughly £105,000 income.

How Affordability Works in the USA, Canada, and Australia
The UK income multiple model is unusual globally. Here is how the other three major English-speaking mortgage markets work.
USA: Debt-to-Income Ratio
US lenders use a Debt-to-Income (DTI) ratio instead of an income multiple. The standard maximum is 43% DTI, your total monthly debts (mortgage, taxes, insurance, credit cards, car loans, student loans) cannot exceed 43% of your gross monthly income.
On a $100,000 salary ($8,333/month), your maximum total debt payment is $3,583. If you have $500 in other monthly debts, the mortgage gets $3,083, which supports roughly a $480,000 loan at 6.5% interest. That works out to about 4.8× income, slightly higher than the UK standard, but it includes all housing costs (property tax, insurance, PMI).
US mortgages come as 15-year or 30-year fixed-rate loans with no automatic renewal, so affordability is about qualification, not stress testing.
Canada: Stress Test + Income Qualification
Canada is the closest to the UK system. Canadian borrowers must pass the mortgage stress test, qualifying at the contract rate plus 2% or 5.25%, whichever is higher. The income multiple is typically 4× to 4.5×, similar to the UK, but the stress test is more restrictive because of the higher qualifying threshold.
The mortgage stress test 3% addition Bank of England uses is similar in spirit to Canada's stress test, though Canada's is slightly tighter. Canadian mortgages also use 1–5 year terms (like the UK), meaning borrowers face periodic refinancing decisions that US 30-year fixed borrowers do not.
Australia: Application-Based Assessment
Australian lenders use an assessment rate approach, they test affordability at a rate higher than the advertised rate (typically 3% above the current rate, similar to the UK). The maximum borrowing is usually 5× to 6× income for high earners with good credit, significantly higher than the UK's 4.5× limit.
Australia also has Lender's Mortgage Insurance (LMI) for borrowers with less than 20% deposit, which adds to upfront costs. However, Australia's mortgage market is the most competitive, cashback offers and rate discounts are common, making it a borrower-friendly market if you shop around.
