How much can I borrow for a mortgage? It’s usually two questions in one: how much mortgage can you get, and how much can you comfortably afford each month? The first depends on your accepted income, existing debts, deposit, and the lender’s criteria. As a rough guide, 4 to 4.5 times your annual income before tax gives a starting estimate, but it isn’t a guaranteed offer. The second depends on your own budget, and it’s the one that decides whether the mortgage feels manageable.
As a rough guide, borrowing 4 to 4.5 times your annual income before tax can provide a starting estimate, but it is not a guaranteed offer. Check your monthly repayments and speak to a mortgage adviser to understand how much you could realistically afford.
TL;DR
- A salary calculation is a starting estimate, not mortgage approval.
- Your mortgage amount and your property budget are different figures.
- Compare repayment costs as well as the amount available to borrow.
- Keep money aside for buying costs and emergencies.
- Check your circumstances with an adviser before committing to a price range.
Before you book viewings, you need a price range you can work with. A quick salary calculation can help, but it cannot tell you what a lender will approve or what you will feel comfortable paying each month. Start with three figures: a possible mortgage amount, the deposit you can use, and a monthly payment that leaves room for the rest of your life. This guide shows how to bring those figures together.
How much mortgage can I get with a £40,000 salary?
Multiplying your gross annual income, before tax, by 4 or 4.5 gives a useful illustration. MoneyHelper describes 4.5 times income as a typical lending cap, while warning that applicants may be offered less. Treat it as a planning reference rather than a universal rule. MoneyHelper’s mortgage affordability guide.
Gross annual income Illustration at 4 times income Illustration at 4.5 times income
| Gross annual income | At 4x income | At 4.5x income |
|---|---|---|
| £30,000 | £120,000 | £135,000 |
| £40,000 | £160,000 | £180,000 |
| £50,000 | £200,000 | £225,000 |
| £60,000 | £240,000 | £270,000 |
| £70,000 (combined) | £280,000 | £315,000 |
| Deposit | Cash deposit | Mortgage needed | LTV |
|---|---|---|---|
| 5% | £12,500 | £237,500 | 95% |
| 10% | £25,000 | £225,000 | 90% |
| 20% | £50,000 | £200,000 | 80% |
| Illustrative savings allocation | Amount |
|---|---|
| Total savings | £35,000 |
| Reserve for buying and moving costs | £5,000 |
| Emergency reserve retained | £5,000 |
| Available deposit | £25,000 |
| Mortgage term | Monthly payment | Total interest |
|---|---|---|
| 25 years | £1,169 | £150,754 |
| 30 years | £1,074 | £186,512 |
| 35 years | £1,009 | £223,938 |
These are arithmetic examples, not eligibility ranges or lending promises. They assume the stated income is accepted in full and do not assess spending, credit history, the property or lender criteria. Your deposit is additional to the mortgage figures shown.
For example, on a £40,000 salary, multiplying by 4.5 gives £180,000. If a lender agreed that amount and you had £20,000 available as a deposit after setting aside buying costs, your purchase budget would be £200,000.
Can I borrow more than 4.5 times my salary?
Some products allow higher income multiples for eligible borrowers. Nationwide’s Helping Hand page, for example, illustrates borrowing at six times income for qualifying first-time buyers, subject to affordability and its product conditions. This does not mean six times income is available to everyone, or that the product is suitable for your circumstances. Nationwide Helping Hand.
Ask an adviser to explain both the amount potentially available and the conditions attached. A larger loan deserves a closer look at the monthly payment.
Mortgage affordability calculator: what it can and can’t tell you
A mortgage affordability calculator takes your income, deposit and outgoings and gives you an estimated borrowing figure. It’s a fast way to test a price range before you book viewings. What it can’t do is apply a particular lender’s policy, so treat the result as a starting point. Two people with the same salary can get different answers once debts, credit history and the type of income are assessed.
Use the estimate to sense-check your budget, then compare it with the monthly payment you’d be happy to carry. If the two numbers are far apart, that gap is exactly what to raise with an adviser.
What do mortgage lenders actually look at?
The income they can accept
Your basic salary may be only part of the picture. Overtime, bonuses and commission can require different treatment. Lenders set policies covering acceptable income, the proportion counted and the evidence required. They must also consider relevant foreseeable changes in income and expenditure. FCA responsible lending rules.
Consider an illustrative applicant earning £40,000 basic pay plus £8,000 in variable pay. At a purely illustrative 4.5 multiplier, counting only basic pay produces £180,000; counting all £48,000 produces £216,000. That £36,000 difference explains why you should ask “which income can be used?” before asking “what multiple can I get?” These are hypothetical calculations, not examples of a particular lender’s policy.
Debts and household spending
Lenders assess commitments and living costs alongside income. These can include credit payments, childcare, maintenance, bills and property charges. Two households earning the same salary may therefore receive different borrowing assessments. MoneyHelper’s affordability guidance.
For your own budget, write down the spending you expect after moving. A cheaper mortgage payment may be offset by a longer commute or higher running costs. Include annual costs by dividing them by 12, so they do not disappear from a monthly worksheet.
Evidence and future affordability
Lenders need evidence of income and commitments. Their assessment can include likely future interest-rate increases, with treatment depending on the mortgage and applicable rules. Where the term runs into retirement, expected retirement income also matters. FCA responsible lending rules.
If you expect a change in working hours, retirement or another major household change, discuss it during the assessment. Build your personal budget around what you reasonably expect to earn and spend.
How does my deposit affect how much I can borrow?
For a given purchase price, a larger deposit reduces the mortgage you need. Loan-to-value, or LTV, expresses the mortgage as a percentage of the property value.
| LTV = mortgage amount ÷ property value × 100 |
| For a property valued and purchased at £250,000: |
| Deposit percentage Cash deposit Mortgage needed LTV |
| 5% £12,500 £237,500 95% |
| 10% £25,000 £225,000 90% |
| 20% £50,000 £200,000 80% |
These are calculations, not confirmation that a suitable mortgage is available. A lower LTV can affect the deal offered, but the borrowing must still meet the lender’s requirements. MoneyHelper on deposits.
Suppose your assessed borrowing figure is £225,000. With a £25,000 deposit, the arithmetic supports a £250,000 purchase before costs. A £50,000 deposit increases that figure to £275,000 without increasing the loan. You would still need the lender to accept the property and the application.
- Do not count every pound of savings as your deposit
- Try this planning worksheet:
- Illustrative savings allocation Amount
- Total savings £35,000
- Reserve for buying and moving costs £5,000
- Emergency reserve retained £5,000
- Available deposit £25,000
The reserves are invented examples, not recommended amounts or fee estimates. Replace them with your own costs, tax position and contingency. Otherwise, your property budget may depend on spending money you need elsewhere.
How much mortgage can I afford each month? Click for Calculator
A borrowing figure only becomes useful when you translate it into a repayment.
The following calculations show a £200,000 capital-and-interest repayment mortgage at an illustrative 5% annual interest rate:
Mortgage term Approximate monthly payment Approximate total interest
25 years £1,169 £150,754
30 years £1,074 £186,512
35 years £1,009 £223,938
Assumptions: monthly repayments, no fees, no overpayments, and an unchanged 5% rate for the entire term. Figures use an annual rate divided by 12 and are rounded; actual lender calculations may differ. The rate is an example, not a current offer or forecast.
In this example, extending from 25 to 35 years reduces the payment by about £160 a month but adds roughly £73,184 in interest. A lower payment can be useful, but you should understand its long-term cost. Choose a comfortable monthly figure before testing the maximum. What would remain for repairs, saving and unexpected costs? What happens if your income falls for a while?
You can use Wiser’s mortgage repayment calculator to explore different loan amounts, rates and terms. It estimates payments from your inputs; it does not determine whether a lender will approve the borrowing.
Why can I afford my rent but not get the mortgage I expected?
It is a reasonable question when your rent is higher than a quoted mortgage payment. But paying rent does not, by itself, establish mortgage eligibility. The lender has to assess the proposed loan using its lending criteria and affordability requirements. FCA responsible lending rules.
Ask what is limiting the figure: accepted income, existing commitments, the proposed term or another condition. That gives you something specific to review. Repeating the same salary calculation will not explain a lender’s decision.
How much can two people borrow on a joint mortgage?
For an initial illustration, add the income you expect the lender to accept from both applicants. Annual salaries of £35,000 and £25,000 total £60,000; multiplying that by 4.5 gives £270,000.
This is a calculation, not a joint mortgage quote. Both applicants’ circumstances need assessment. When building your own budget, also test a period with less household income rather than assuming two full salaries will always be available.
How much can I borrow if I am self-employed?
Start with evidence of income rather than your business’s sales total. MoneyHelper explains that self-employed applicants may need bank statements, business accounts and tax information, commonly covering two or three years. Exact requirements vary. MoneyHelper’s income guidance.
For a useful first conversation, bring your latest accounts and tax documents and explain any substantial change in trading. Ask which income figure the lender would assess and over what period. Do not plug turnover into a salary calculator and treat the answer as a personal borrowing figure.
How to get a realistic budget before viewing homes
List your income accurately. Separate basic pay from variable earnings and identify what evidence is available.
- Work out your usable deposit. Keep buying costs and any reserve separate.
- Choose a comfortable payment. Include expected costs after the move.
- Discuss your figures with an adviser. Ask what assumptions could change the result.
- Consider a mortgage agreement in principle. Use it to inform your search, while recognising it is not a final mortgage offer.
A mortgage agreement in principle is also called a decision in principle or mortgage in principle. Wiser explains the initial assessment and the information you may need on its mortgage-in-principle page. Check whether the chosen lender uses a soft or hard credit search before proceeding.
If the budget is below your target, ask the adviser to compare specific alternatives. Would waiting for a commitment to finish help? Would more deposit make the intended purchase possible? What would a different term cost overall? Avoid draining your savings or making financial changes solely to improve a calculator result.

FAQ
How much can I borrow on a £50,000 salary?
For illustration, 4 times £50,000 is £200,000 and 4.5 times is £225,000. Neither figure is an offer. A lender needs to assess your circumstances, and your deposit is separate from the mortgage amount.
Does having a 10% deposit mean I can borrow the other 90%?
It means a loan for the remaining price would be at 90% LTV, assuming the purchase price and accepted valuation match. It does not confirm that your income and circumstances support that loan.
Do debts reduce mortgage borrowing?
Credit commitments form part of the assessment. There is no universal calculation that converts each pound of debt into a fixed reduction in mortgage borrowing. Ask for an assessment using your actual balances and payments.
Does my credit history matter?
Yes. Check your credit report for errors and missed payments before applying. A salary calculation cannot tell you how your credit history will affect a lender’s decision. MoneyHelper on credit reports.
Can first-time buyers borrow more?
Some first-time-buyer products have enhanced borrowing criteria, but eligibility is product-specific. Being a first-time buyer does not automatically increase the amount you can afford. Nationwide’s Helping Hand example.
Is a mortgage calculator result guaranteed?
No. A repayment calculator shows the cost of the loan you enter under its assumptions. A borrowing calculator estimates potential lending from the information provided. Neither replaces a lender’s assessment or a formal offer.
Knowing how much you can borrow for a mortgage is about more than multiplying your annual salary by four or five. Lenders look at your income, regular expenses, existing debts, credit history, deposit and overall financial circumstances before deciding how much they may be willing to lend.
Every applicant is different, and the amount you could borrow will depend on the lender’s criteria and your individual situation. Understanding your borrowing potential before you start viewing properties can help you set a realistic budget and move forward with greater confidence.
If you’re planning to buy your first home, move house or remortgage, getting the right advice early can make the process much easier.
