Here you will learn what the repayments will be and how much you need to earn to afford a £500,000 mortgage, as well as the best way to get one.
Calculate £500k mortgage repayments
Example:
The average monthly payments on a £500,000 mortgage are £2,639, based on typical market conditions in the UK. We worked this figure out based on a capital repayment mortgage with a 4% interest rate taken out over a term length of 25 years.
Paying this amount for your mortgage across the full term would mean paying back a total of £791,755, but most people’s mortgage payments change when they remortgage.
The exact repayments on your mortgage will depend on the rate you qualify for, the type of product you choose and the term length you agree.
To get a more accurate representation of your actual repayments, it's best to speak to a broker, who can consider your specific circumstances better than a calculator can.

Factors that will affect your repayments
Here we have broken down the main variables that shape the exact cost of a £500,000 mortgage, complete with example calculations for context.
Other amounts
If you need to borrow slightly more or less than £500k, you may find the following pages useful:
Interest rate
Mortgage lenders decide which rate to offer you after reviewing the overall strength of your application, specifically how much deposit you have and your credit history.
This table shows how the cost of a £500k mortgage can change depending on the rate you are given. These calculations are for a capital repayment mortgage with a 25-year term.
Mortgage Amount | Interest Rate | Monthly Repayments | Overall Repayment |
£500k | 3.5% | £2,503 | £750,935 |
£500k | 4% | £2,639 | £791,755 |
£500k | 4.5% | £2,779 | £833,749 |
£500k | 5% | £2,923 | £876,885 |
£500k | 5.5% | £3,070 | £921,131 |
£500k | 6% | £3,222 | £966,452 |
Term length
The average mortgage term in the UK is 25 years but most lenders will give you the option of longer or shorter agreements. Longer mortgages have lower monthly payments but cost more overall due to having extra interest instalments to pay.
The table below shows the impact of term lengths on a £500,000 mortgage, with calculations based on a capital repayment mortgage with a 4% interest rate.
Mortgage Amount | Term Length | Monthly Repayments | Overall Repayment |
£500k | 10 years | £5,062 | £607,471 |
£500k | 15 years | £3,698 | £665,719 |
£500k | 20 years | £3,030 | £727,176 |
£500k | 25 years | £2,639 | £791,755 |
£500k | 30 years | £2,387 | £859,348 |
£500k | 35 years | £2,214 | £929,827 |
£500k | 40 years | £2,090 | £1,003,052 |
Mortgage type
The mortgage product type will have a bearing on the cost of a £500k mortgage as fixed rate and variable rate mortgages have their own costs, fees and rates.
The repayment type will be equally relevant as not all mortgages are capital and repayment. Some have an interest only repayment type, which means you would only have to pay off the interest each month and settle the loan debt at the end of the term.
The table below shows how much a £500k mortgage will cost if taken on an interest-only agreement, across different interest rates and a term length of 25 years.
Mortgage Amount | Interest Rate | Interest-only Payments (Monthly) | Overall Repayment |
£500k | 3.5% | £1,458 | £937,500 |
£500k | 4% | £1,667 | £1,000,000 |
£500k | 4.5% | £1,875 | £1,062,500 |
£500k | 5% | £2,083 | £1,125,000 |
£500k | 5.5% | £2,292 | £1,187,500 |
£500k | 6% | £2,500 | £1,250,000 |
Our expert says
“At half a million pounds, monthly capital repayments on a standard 25-year repayment plan can exceed £2,700 depending on prevailing rates. To balance long-term debt reduction with manageable day-to-day liquidity, many high-earning applicants use 'part-and-part' mortgages.
Placing £350,000 on capital repayment and £150,000 on interest-only significantly lowers mandatory monthly cash outgoings, allowing you to service the interest-only portion via annual bonuses or investment vehicles.”
Neil Mulhearn How much a £500,000 buy-to-let mortgage costs
The repayments on a £500,000 buy-to-let mortgage are calculated in the same way as they are for residential mortgages, but the main difference to their cost is that interest rates are usually higher. These mortgages are usually agreed on an interest-only basis too.
With these factors in mind, the typical cost of a £500,000 buy-to-let mortgage would be around £1,875 per month, which would mean paying £1,062,500 across a 25-year term.
An example rate of 4.5% and an interest-only payment type was used for this calculation.
How much do you need to earn to get a £500,000 mortgage?
Use our affordability calculator below to get a rough idea of whether you qualify.
Example:
You will need to earn around £111,000 a year to afford a £500,000 mortgage at 4.5 times your annual salary. However, lenders often stretch to 5-6 times income for higher earners, but keep in mind that their criteria is usually more stringent than at lower loan values.
If your income falls short, it might still be possible to get approved for a mortgage of £500k. Some lenders allow borrowers to submit supplemental income, such as benefits or freelance work, alongside their main salary, and others allow up to four applicants on a mortgage.

FAQs
The mortgage amount doesn’t usually make a difference to the rate you are offered, so they are no different for £500,000 loans compared to larger or smaller amounts.
The rate you qualify for will depend on how much deposit you have (the more, the better) and how clean your credit history is, among other factors.
