The repayments you make on a £600,000 mortgage will vary depending on your mortgage type. Mortgage repayments are determined by the length of your term, the type of mortgage you get, and your interest rate.

Opting for longer loan terms leads to lower monthly payments but results in paying more overall. A higher interest rate means you’ll pay more. For instance, with an interest-only mortgage, you only cover the interest charges, not the principal amount borrowed.

How much does a £600,000 mortgage cost per month?

At the time of writing (June 2024) the average monthly repayments on a £600,000 mortgage are £3,508. This is based on current interest rates being around 5%, a typical mortgage term of 25 years, and opting for a capital repayment mortgage. Based on this, you would repay £1,052,262 over the mortgage term.

However, if you secure a mortgage with a longer term, this will result in smaller monthly repayments but you’ll pay more in total over the term of the mortgage.

To get an idea of what you might repay, talk to one of the advisors we work with. They can help you secure favourable terms and lower repayments than you might get if you try to secure a mortgage by yourself.

How much do you need to earn to get a £600,000 mortgage?

The amount you can borrow is based on your salary. Most lenders will loan 4 and 4.5 times your annual salary. You’d need an annual income between £120,000 to £135,000 to be approved for a £600,000 mortgage. This is significantly above the average UK annual salary, currently £34,900 (June 2024).

If you do not earn the mentioned figures, it is unlikely that you will be approved. However, you can get a joint mortgage with your partner for example. You can combine your earnings to increase your chances of getting approved for a £600k mortgage.

Some lenders may also be willing to offer 5 times or possibly even 6 times annual salary. In this circumstance, you’d need to earn £100,000 to be eligible for a £600,000 mortgage. But this is often only available to certain professions, such as a doctor or lawyer, with high or stable income.

In these circumstances, it’s best to consult with a broker who can indicate which lenders can offer this and whether you’d meet the lender’s affordability criteria.

Example calculations

This table shows how your income and the provider’s income multiples combine to show your maximum borrowing capacity:

Income 4x income 4.5x income 5x income 5.5x income 6x income
£120,000 £480,000 £540,000 £600,000 £660,000 £720,000
£130,000 £520,000 £585,000 £650,000 £715,000 £780,000
£140,000 £560,000 £630,000 £700,000 £770,000 £840,000
£150,000 £600,000 £675,000 £750,000 £825,000 £900,000
£160,000 £640,000 £720,000 £800,000 £880,000 £960,000

The above table is for comparative purposes only. You should talk to your mortgage lender or broker for the most up-to-date information on affordability criteria.

If you’d like to see how this works out for yourself, based on your annual income, take a look at our mortgage affordability calculator below:

Most lenders would consider letting you borrow

This is based on 4.5 times your household income, the standard calculation used by the majority of mortgage providers. To borrow more than this, you will need to use a mortgage broker to access specialist lenders.

Some lenders would consider letting you borrow

This is based on 5 times your household income, a salary multiple you might struggle to qualify for without the help of a broker. This income multiple is not widely available to customers who are applying directly with a lender.

A minority of lenders would consider letting you borrow

This is based on 6 times your household income, a salary multiple you will struggle to get without a broker. Six-times salary mortgages are usually only available under very specific circumstances.

How much deposit do you need for a £600,000 mortgage?

Currently, the minimum deposit requirements imposed by lenders for a residential mortgage are between 5%-10% – this is based on the property value NOT the mortgage amount.

So, if you were buying a property with a value of £600,000 (rather than borrowing this amount) you’d need a deposit of between £30,000-£60,000 at least, and then your mortgage would be between £570,000-£540,000.

It’s not impossible to secure a mortgage for £600,000 with no deposit, but this is extremely rare.

For a more complex application, where there may be a bad credit issue, which will reduce the pool of lenders available, you may need a higher deposit of at least 25%.

For a buy-to-let mortgage, most lenders require a minimum of 20%. However, an experienced mortgage broker may find some lenders that ask for less.

Keep in mind that the larger your deposit, the better your chances of qualifying for competitive interest rates and mortgage terms. Lenders typically offer their best rates to mortgages with the lowest loan-to-value (LTV) ratios. Most lenders have a maximum LTV of 95%, requiring a minimum deposit of 5%.

Some lender’s limit will be lower than 95% but you’d need to put down a bigger deposit.

You can see how this works on our calculator below.

LTV Calculator

This calculator will tell you what your loan-to-value (LTV) ratio is, based on the property's value, your deposit/equity and the amount you're borrowing.

This means that most mortgage providers will consider your deposit amount to be more than satisfactory, but speaking to a broker is still recommended to ensure you get the best deal.

This means you’re likely to meet the deposit requirements at most lenders, but since many reserve their best rates for those with higher deposits, speaking to a broker is recommended.

Many mainstream mortgage providers would consider this high and be reluctant to lend. Applying through a mortgage broker may be necessary to find a specialist low deposit mortgage lender.

LTVs have a direct impact on the rates available to you - speak to a mortgage broker and find out how to get the best deal based on your ratio.

How to get a £600,000 mortgage

After finding a property you like and making some calculations, your next step in your mortgage application should be to find a mortgage broker with experience in arranging mortgages of this amount. This will boost your chances of getting approved at the best terms available.

Using our free broker-matching service you can speak to the right broker by simply enquiring online. They’ll be able to help with:

  • Deposit requirements: You’ll need to save a minimum deposit of 5% to 10% for a £600,000 mortgage. How much this figure will be depends on the value of the property, but a 10% deposit on a £600,000 house would be £60,000. A simple way to help you save money is to set up a savings account and put a percentage of your monthly wage, around 10 to 15%, into the account each month.
  • Downloading and optimising your credit reports. It’s important to review your credit history before applying for a mortgage. Check for any inaccuracies or outdated information that can be removed beforehand.
  • Gathering all the necessary paperwork required for your application: Your broker will be able to guide you through the application process and all the typical documents required – proof of income, at least three months of bank statements, personal ID, proof of address, evidence of deposit, latest P60 form etc.
  • Working out how much you can borrow. You might assume that £600,000 is the maximum you can borrow for a mortgage based on typical lender salary multiplier calculations. However, this might not be the case. A mortgage broker can evaluate your situation and determine your eligibility for better deals from lenders. This could potentially allow you to borrow more at improved interest rates.
  • Finding the right lender and securing the best deal for you. Your mortgage broker will be able to identify those lenders offering the best interest rate terms available across the whole market. This will save you time and, potentially, some money too.
  • Guiding you through the Mortgage Process: Applying for a mortgage can be challenging, especially if it’s your first application. The right mortgage broker can help you navigate any challenges, protect your interests, and offer assistance if things go wrong.

Example monthly repayments for a £600,000 mortgage

The table below shows how monthly payments on a £600,000 mortgage can change depending on the rate and term.

Interest rate 15 years 20 years 25 years 30 years 35 years
1% £3,591 £2,759 £2,261 £1,930 £1,694
2% £3,861 £3,035 £2,543 £2,218 £1,988
3% £4,143 £3,328 £2,845 £2,530 £2,309
4% £4,438 £3,636 £3,167 £2,864 £2,657
5% £4,745 £3,960 £3,508 £3,221 £3,028
6% £5,063 £4,299 £3,866 £3,597 £3,421
7% £5,393 £4,652 £4,241 £3,992 £3,833
8% £5,734 £5,019 £4,631 £4,403 £4,262

Repayments for interest-only mortgages remain the same regardless of the term. So, for example, the repayment shown for 6% – £3,000 per month – would be the same if you opted for a 15-year term or a 30-year term as the capital owed doesn’t reduce and is paid off in full at the end using a separate repayment vehicle.

Interest rate 1% 2% 3% 4% 5% 6% 7% 8%
Any term £500 £1,000 £1,500 £2,000 £2,500 £3,000 £3,500 £4,000

For the purpose of these tables, we assume the interest rate stays the same for the full length of the mortgage. Interest rates can change if you decide to remortgage on to a different rate or move from a fixed or discounted deal on to the lender’s standard variable rate (SVR).

With the Bank of England base rate currently at 5.25% (June 2024) and the average mortgage rates between 5% to 6% the repayment figures along these rows in the table above would be the most realistic at present. This can change as and when the base rate is changed.

Factors that affect monthly repayments

Each of the following factors outlined below will have a direct impact on your mortgage repayments.

Interest rate

Securing the best (lowest) interest rate terms available means your repayments will be as low as possible, based on market conditions at the time of your application.

The strength of your application and deposit size will determine how many mortgage lenders are willing to consider you for a mortgage and, as a result, this means you’ll have access to the best available rates.

Other factors, such as your credit history, age and employment status can also impact the interest rate you qualify for as this could result in a smaller pool of lenders willing to consider you for a mortgage.

Mortgage term

Not all mortgages have to be taken out over 25 years. If you demonstrate that affordability isn’t an issue, you can often shorten the term, resulting in higher monthly payments but saving on interest over the loan period. Certain lenders may permit overpayments, which can assist you in paying off your mortgage faster and reducing the total interest paid.

If this is something you would consider, a mortgage broker can advise on the options available to you. This is important, as you may face early repayment charges if you repay more than 10% each year.

If you need to borrow £600,000 for a home but affordability is an issue, you can extend your loan term to a maximum of 40 years to make your monthly payments more manageable. It’s important to note that not all lenders offer 40-year terms, and approval is more likely if you’re younger.

If you don’t meet the eligibility criteria for mainstream lenders, you might still be able to secure a favourable rate by approaching a specialised lender that understands your circumstances. This can include applicants looking for bad credit mortgages or mortgages for self-employed people. The best way to find these lenders is by using the services of an experienced mortgage broker.

Mortgage Type

How you choose to pay back your mortgage is also a factor that can affect your monthly repayments.

Broadly speaking there are three different types available:

  • Fixed-rate mortgages: These types of mortgages make budgeting easier as you tie in a fixed rate for a fixed term so you know exactly what your monthly payments will be for several years (usually between two and five).
  • Variable rate mortgages: As the name suggests, these types of mortgages have rates that can vary rather than remain fixed. As such they can be slightly more risky than a fixed-rate mortgage but can result in lower monthly repayments during the term. Types of variable rates include tracker mortgages (see below), discounted rate mortgages and standard variable rate (SVR) mortgages.
  • Tracker mortgages: This type of mortgage has a variable rate that typically follows the Bank of England base rate by a set percentage. Some lenders set a minimum and maximum rate to provide stability. Generally, these rates are lower than the fixed rates available at the time of getting the mortgage. Many lenders provide discount tracker rates to assist in lowering your monthly payments.

Your age

Most lenders, particularly high street ones, set a maximum age limit for their mortgage products. This means that you will usually be required to have repaid your mortgage by the time you’re 75 to 85.

The older you are, the shorter the term is likely to be. However, not all lenders apply maximum age limits, so if you’re an older borrower, you might be able to achieve the term you want with the right lender. Alternatively, you can look at equity release products, that are intended for over 55s.

Your credit history

If you have blots on your credit history, this might result in your lender charging you a higher interest rate to mitigate the risk of lending to you. A broker specialising in mortgages with bad credit can help you find the best rates given your circumstances.

Additional mortgage costs to consider

There are a few other additional charges to think about that may impact the monthly costs when setting up a mortgage worth £600,000. Speaking to a mortgage broker about the costs listed below will give you more information about what they entail and ensure there are no unpleasant surprises.

Product fees

Some mortgages come with fees to set them up, such as some of the ones listed below:

  • Arrangement fee: Most mortgages include an arrangement fee (also known as a ‘product fee’). These fees usually depend on the complexity of the application and can range from anywhere up to around £2,000. In some cases, these can be added to your mortgage, but that will increase your monthly payment slightly and you will end up paying interest on the fee.
  • Booking fee: Not all mortgages require a booking fee, but those that do will typically ask for around £100 – £200.
  • Valuation feeLenders insist on a valuation fee to confirm the purchase price is right and protect their investment. This is likely to cost you in the region of £300.
  • Land registry fee: This is essentially an admin fee you pay to the Land Registry for them to change the register entry to your name. It only applies to properties valued at £100,001 and above. The fee ranges from £45 to £145 depending on the property’s value.
  • Solicitors fee: Also known as the ‘conveyancing fee’, this is the amount you pay your solicitor for their work on the deal. These can vary considerably but as a general guide, expect to pay between £800 and £1,500.
  • Broker fee: If you decide to use their services a broker will typically charge either a percentage of the amount borrowed (usually up to 1%) or a fixed fee (between £500-£1,000 depending on the complexity of the application).


When considering a mortgage, you will likely need to factor in additional insurance costs. These may include:

  • Home insurance: Covers your property against damage or loss.
  • Life insurance: Provides coverage for the mortgage in case of your death.
  • Income protection: Helps if you’re unable to work due to illness or injury.
  • Critical illness cover: Assists if you’re diagnosed with a serious medical condition

Stamp duty

Depending on the home’s value and whether it’s your main residence, you might be required to pay stamp duty. First-time buyers or those purchasing residential properties under £250,000 are exempt from this tax.

These costs typically arise during the purchase process. While they don’t directly impact monthly payments, they are an additional expense to consider in your calculations.
