What factors could affect your repayments?
Here we will explore the factors that determine what your exact repayments will be on a £400,000 mortgage. The tables below contain example calculations for context.
Term length
Longer and shorter term lengths than the standard 25 years are available. Lengthier terms come with lower monthly repayments but will cost you more in interest overall.
The table below shows how different term lengths affect the repayments on a £400k capital repayment mortgage, using a 5% interest rate for example purposes.
Mortgage Amount | Term Length | Monthly Repayments | Overall Repayment |
| £400k | 10 years | £4,242 | £509,114 |
£400k | 15 years | £3,163 | £569,371 |
£400k | 20 years | £2,640 | £633,558 |
£400k | 25 years | £2,338 | £701,508 |
£400k | 30 years | £2,147 | £773,023 |
£400k | 35 years | £2,091 | £847,875 |
£400k | 40 years | £1,929 | £925,817 |
Interest rate
Factors including how much deposit you have and your credit situation will determine your interest rate. The table below shows how different rates can affect the monthly repayments on a £400,000 capital repayment mortgage, using a 25-year term length for example purposes.
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 |
Mortgage type
Your monthly repayments will also come down to the type of mortgage you select. There are two main areas where you will have a choice on this: the repayment type and the product type.
Product type
Fixed-rate mortgages are the most common type in the UK. Your interest payments will be consistently the same during an introductory rates period (usually 2-5 years, but sometimes longer) before reverting to the lender’s standard variable rate (SVR), which is usually higher.
The most common alternative is a type of variable rate agreement called a tracker mortgage. With this product type, your interest charges can change from one period to the next as these mortgages are tied to an external marker, such as the Bank of England’s base rate.
Repayment type
How much you will pay in interest on your £400,000 mortgage will also come down to the repayment type. Capital repayment, which involves repaying some of the mortgage debt plus interest each month for the duration of the agreed term is the most common type.
A popular alternative is an interest-only mortgage. With this repayment type, only interest payments are mandatory each month and the debt itself is cleared at the end of the term using a pre-approved repayment vehicle, such as investments or the sale of the property.
The table below shows what the repayments on a £400k interest-only mortgage will look like based on a range of different rates and an example term length of 25 years.
Mortgage Amount | Interest Rate | Interest-only Payments (Monthly) | Overall Repayment |
£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 |

FAQs
All of the mortgage applicants would need a combined salary of somewhere in the £90k to £100k bracket to afford a mortgage of this amount as most lenders will cap your maximum borrowing at between 4 and 4.5 times annual salary. Other lenders will stretch to 5 times income or even 6 times income, so you may have options if you earn less than this figure.
If the property you are buying has is valued at £400k, you will typically need between £20,000 and £40,000 to put down as a deposit. This means you will need a mortgage of between £380k and £360k, which could cost roughly between £2,221 and £2,105 per month based on average interest rates at the time of writing and the standard term length of 25 years.
Choosing an Adviser
Selecting a qualified and experienced mortgage adviser is of great importance. To choose a suitable adviser, evaluate their qualifications, experience, and reputation, and ensure they are regulated by the Financial Conduct Authority (FCA).
Read reviews from previous clients and make sure they provide a clear explanation of the products and services they offer, as well as the fees and charges associated with them.
