How Much Can I Borrow for a Mortgage in the UK?
Most UK mortgage lenders calculate how much you can borrow based on a multiple of your annual income — typically between 4× and 4.5× your salary (or combined salary if buying with a partner). Some lenders will go up to 5× income for higher earners or professionals.
Your deposit size also determines your Loan to Value (LTV) ratio. A lower LTV (larger deposit) typically means better interest rates. Most lenders require a minimum 5–10% deposit, and the best rates are usually available at 60–75% LTV.
Example Mortgage Borrowing by Income
| Annual Income | At 4× (max) | At 4.5× (typical) | At 5× (high earner) |
|---|---|---|---|
| £25,000 | £100,000 | £112,500 | £125,000 |
| £35,000 | £140,000 | £157,500 | £175,000 |
| £50,000 | £200,000 | £225,000 | £250,000 |
| £75,000 | £300,000 | £337,500 | £375,000 |
| £100,000 | £400,000 | £450,000 | £500,000 |
| £60,000 + £40,000 | £400,000 | £450,000 | £500,000 |
Frequently Asked Questions
How much can I borrow for a mortgage? ▼
Most lenders offer 4–4.5× your annual income. With a combined income of £80,000, you could typically borrow £320,000–£360,000 at standard multipliers, subject to credit and affordability checks.
What is LTV and why does it matter? ▼
LTV (Loan to Value) is the ratio of your mortgage to the property's value. A 90% LTV means you have a 10% deposit. The lower the LTV, the better the interest rates you will be offered — 60–75% LTV usually gets the best deals.
Do I need a 10% deposit? ▼
You can get a mortgage with a 5% deposit, but you will pay higher interest rates and have fewer lenders to choose from. A 10% deposit significantly opens up your options. A 25% or more deposit typically gets the most competitive rates.
How do outgoings affect what I can borrow? ▼
Lenders carry out affordability assessments looking at your monthly outgoings including credit cards, loans and car finance. Higher outgoings reduce the amount you can borrow, even if your income-based calculation is high.
