How Much Does A £500,000 Mortgage Cost Per Month?
A £500,000 mortgage is a significant financial commitment, so it is important to understand what the monthly repayments could look like before applying.
The cost of a £500,000 mortgage will depend on the interest rate, mortgage term, repayment type and the lender’s affordability assessment. As a broad guide, a £500,000 repayment mortgage could cost around £2,640 to £2,925 per month over 25 years, based on interest rates between 4% and 5%. On an interest-only basis, the monthly payment would be lower, but the original £500,000 balance would still need to be repaid at the end of the mortgage term.
At Kerr & Watson, we help clients arrange mortgages by reviewing affordability, income structure, deposit size, lender criteria and whether repayment or interest-only options may be suitable.
Not Sure Whether You Could Afford A £500,000 Mortgage?
A £500,000 mortgage is a large commitment, and the right lender can make a significant difference to both the amount you can borrow and the product available.
This can be particularly important where income includes bonuses, commission, dividends, retained profits, foreign currency income, investment income or self-employed earnings.
At Kerr & Watson, we can assess your income, deposit and wider circumstances to help you understand what may be affordable and which lenders may be suitable.
Example Monthly Repayments On A £500,000 Mortgage
The table below gives an indication of how much a £500,000 repayment mortgage could cost each month over different terms and interest rates.
| Interest Rate | 20 Years | 25 Years | 30 Years | 35 Years |
|---|---|---|---|---|
| 4% | £3,030 | £2,639 | £2,387 | £2,214 |
| 4.5% | £3,163 | £2,779 | £2,534 | £2,366 |
| 5% | £3,300 | £2,923 | £2,684 | £2,523 |
| 5.5% | £3,439 | £3,070 | £2,839 | £2,685 |
| 6% | £3,582 | £3,222 | £2,998 | £2,851 |
These figures are for illustration only and assume a capital repayment mortgage.
Your actual monthly payment will depend on the product available at the time, your deposit, lender criteria and your personal circumstances.
How Much Would A £500,000 Interest-Only Mortgage Cost?
An interest-only mortgage is cheaper each month because you are only paying the interest, not reducing the original mortgage balance.
For example, a £500,000 interest-only mortgage would cost approximately:
| Interest Rate | Monthly Interest-Only Payment |
|---|---|
| 4% | £1,667 |
| 4.5% | £1,875 |
| 5% | £2,083 |
| 5.5% | £2,292 |
| 6% | £2,500 |
This can make the monthly payment significantly lower than a repayment mortgage, but the full £500,000 would still need to be repaid at the end of the term. Lenders will usually want to see a credible repayment strategy, such as investments, sale of property, downsizing or other acceptable assets.

How Much Deposit Do You Need For A £500,000 Mortgage?
The deposit needed will depend on the property price and the loan-to-value available from the lender.
For example, if you are borrowing £500,000:
| Deposit Size | Approximate Property Price | Deposit Amount |
|---|---|---|
| 10% Deposit | £555,556 | £55,556 |
| 15% Deposit | £588,235 | £88,235 |
| 20% Deposit | £625,000 | £125,000 |
| 25% Deposit | £666,667 | £166,667 |
| 40% Deposit | £833,333 | £333,333 |
A larger deposit can improve lender choice and may give access to more competitive rates. It can also help where affordability is tight, income is complex or the property is higher value.
What Salary Do You Need For A £500,000 Mortgage?
The income needed for a £500,000 mortgage will depend on the lender’s affordability assessment rather than income alone.
As a rough guide, if a lender used income multiples between 4 and 5 times income, a £500,000 mortgage could require household income of around £100,000 to £125,000. Some lenders may consider higher income multiples for strong applicants, particularly where there is a large deposit, stable income and limited debt.
However, income multiples are only part of the picture. Lenders will also assess regular commitments, credit cards, loans, childcare, school fees, dependants, pension contributions, age, retirement plans and overall household expenditure.
This is why two households earning the same income may be offered very different mortgage amounts.
Is A £500,000 Mortgage A Large Mortgage?
A £500,000 mortga
ge is a significant mortgage commitment, although it may still fall within the standard lending range for many high street lenders.
The way a lender assesses the case will depend on the overall circumstances. A straightforward employed applicant with a strong deposit and limited debts may have a wider range of options, while a self-employed applicant, contractor, company director or applicant with complex income may need a more careful approach.
The key point is that a £500,000 mortgage should not be assessed purely by looking at the loan size. The lender will also consider income structure, deposit, affordability, credit profile, property type and mortgage term.

What Affects The Cost Of A £500,000 Mortgage?
The monthly cost of a £500,000 mortgage is mainly affected by the interest rate, mortgage term and repayment type, but the lender you qualify for can be just as important.
A lower interest rate will reduce the monthly payment, while a longer mortgage term can make the payment more manageable. However, extending the term usually means paying more interest overall. A repayment mortgage will reduce the balance over time, whereas an interest-only mortgage keeps the monthly payment lower but leaves the original loan amount to be repaid at the end.
Your deposit can also make a significant difference. A lower loan-to-value can improve lender choice and may help you access better rates. Lenders will also consider your income type, age, credit history, property type and overall financial position before deciding what they are prepared to offer.
Other Costs To Consider With A £500,000 Mortgage
The monthly mortgage payment is only one part of the overall cost. You may also need to budget for arrangement fees, valuation fees, legal fees, broker fees, moving costs and stamp duty.
Stamp duty can be a significant cost, particularly if you already own another property or are buying a second home. The exact amount will depend on the purchase price, your buyer status and whether any additional property surcharge applies.
If you are remortgaging rather than buying, stamp duty will not usually apply, but there may still be valuation, legal, arrangement or early repayment charges to consider.
Getting A £500,000 Mortgage With Complex Income
Mortgage applications can become more detailed where income is not made up of a simple basic salary. This may include bonuses, commission, overtime, dividends, retained company profits, self-employed income, investment income, trust income, foreign currency income or income from multiple sources.
Some lenders will use this income more generously than others. For example, one lender may only use a percentage of bonus or commission, while another may take a stronger view if there is a consistent track record. Self-employed applicants may also find that lender choice varies depending on whether income is taken as salary, dividends, net profit or retained profit.
This is why a £500,000 mortgage should not be assessed purely by looking at one income multiple. The structure and reliability of the income can be just as important as the amount earned.
