If you are applying for a £400,000 mortgage, your first step should be to run some calculations and work out how much it will cost you to borrow this amount.
Here you will learn what factors determine the cost of a mortgage of this size, how to calculate it yourself, and what to do after tallying up those numbers.
How much does a £400k mortgage cost per month?
The monthly cost of a £400,000 mortgage is approximately £2,111. These would be your repayments if you were to take out a home loan of this amount on a capital repayment basis with a 4% interest rate over 25 years, which is representative of an average UK mortgage.
If you were to take out this exact mortgage, you would repay a total of £633,404 by the end of the term, but keep in mind that your repayments may change if you remortgage.
The exact cost of your mortgage repayments can vary depending on the type of mortgage you choose, the interest rate you qualify for and the term length you agree.

Factors that impact the cost of your mortgage
The true cost of your £400k mortgage will depend on the interest rate, term length, and the type of mortgage you choose. Here we will break down how these variables come into play.
Interest rate
The interest rate a mortgage lender is willing to offer you will depend on the overall strength of your application, but largely on the amount of deposit you have and your credit history.
The table below shows how the cost of a £400k mortgage can vary across different rates.
Mortgage Amount | Interest Rate | Monthly Repayments | Overall Repayment |
£400k | 3.5% | £2,002 | £600,748 |
£400k | 4% | £2,111 | £633,404 |
£400k | 4.5% | £2,223 | £666,999 |
£400k | 5% | £2,338 | £701,508 |
£400k | 5.5% | £2,456 | £736,905 |
£400k | 6% | £2,577 | £773,162 |
Term length
Standard mortgage terms in the UK are 25 years but longer and shorter agreements are available. Taking out a £400,000 mortgage over a longer period means paying less each month, but more in interest overall and therefore a higher amount in the long run.
The table below shows how the cost of a £400k mortgage can vary over different terms.
Mortgage Amount | Term Length | Monthly Repayments | Overall Repayment |
£400k | 10 years | £4,050 | £485,977 |
£400k | 15 years | £2,959 | £532,575 |
£400k | 20 years | £2,424 | £581,741 |
£400k | 25 years | £2,111 | £633,404 |
£400k | 30 years | £1,910 | £687,478 |
£400k | 35 years | £1,771 | £743,862 |
£400k | 40 years | £1,672 | £802,442 |
Mortgage type
Different mortgage product types such as fixed and tracker mortgages have their own specific interest rates, so cost will vary depending on which option you go for.
In addition to the mortgage product type, the repayment type you choose will also have a bearing on the repayments for a £400k mortgage. The most common type in the UK is capital repayment, with which you repay some of the debt plus interest each month.
The main alternative is interest-only, which would involve paying only the interest on your £400k mortgage each month and settling the loan at the end of the term. The table below shows what this would mean for the monthly payments on a mortgage of £400k.
Mortgage Amount | Interest Rate | Interest-only Payments (Monthly) | Overall Repayment (Interest-Only) |
£400k | 3.5% | £1,167 | £750,000 |
£400k | 4% | £1,333 | £800,000 |
£400k | 4.5% | £1,500 | £850,000 |
£400k | 5% | £1,667 | £900,000 |
£400k | 5.5% | £1,833 | £950,000 |
£400k | 6% | £2,000 | £1,000,000 |
How much do you need to earn to get a £400k mortgage?
Mortgage lenders in the UK let eligible applicants borrow between 4 times and 4.5 times their annual salary, so you would need to earn between £90k and £100k bracket. However, a smaller number of lenders will stretch to 5-6 times salary under the right circumstances.
