Welcome to our guide to £550,000 mortgage repayments. Here you will learn how to calculate how much a mortgage of this amount would cost each month, what factors determine this, and what to do after running your calculations.
How much are the repayments on a £550k mortgage?
A £550,000 mortgage would cost you around £2,903 per month under the current market conditions. This calculation is for a capital repayment mortgage with a 4% interest rate and a term of 25 years, all of which is representative of the UK market right now.
If you were to take out a mortgage of this size on these terms, you would repay a total of £870,931 by the end of the term, unless you make changes to the agreement along the way.
Your exact mortgage repayment may vary as there are factors that can make them rise or fall, including the interest rate you qualify for and the type of mortgage you choose.
We explore each of these variables in detail throughout this guide.
Calculate your mortgage repayments
You can work out the repayments on a £550k mortgage for yourself by using our calculator below. This tool is set up to return results for this specific amount but the mortgage size can be changed manually, as can the interest rate, term length and repayment type.
Factors that will determine your repayments
The exact amount you pay each month for a £550k mortgage will depend on these factors:
- Interest rate: The rate you qualify for will depend on how much deposit you have and the overall strength of your application. The lowest rates are typically reserved for borrowers with low LTVs (60% down) and clean credit.
- Term length: Standard mortgage terms are 25 years but longer and shorter agreements are available. Stretching a £550k mortgage over a lengthier term means lower monthly payments but paying more overall due to extra interest instalments.
- Mortgage type: Different mortgage product types such as fixed and tracker-rate mortgages have specific rates and fees attached, and therefore affect the overall cost. The lowest rates right now tend to be attached to 5-year fixes.
- Repayment type: Most mortgages in the UK are capital repayment but the main alternative is interest-only. The monthly cost of a £550k interest-only mortgage will be quite different as you only need to pay the interest charges during the term.
We will now explore these variables in depth with example calculations for context.

FAQs
When applying for a £550k mortgage, you should be aware that the following fees may also apply, on top of your repayments:
- Product fees: Can range between nothing and £2,000. Fee-free deals often come with higher rates, but the fee itself can sometimes be added to the mortgage.
- Valuation fee: Some lenders will expect you to foot the cost of having the property you’re buying valued, and this can set you back between £250-1,500.
- Legal fees: Can range from a few hundred to several thousand pounds.
- Stamp duty: Payable if you are not a first-time buyer. You can find out exactly how much your bill will be in our stamp duty guide.
- Admin costs: This includes the booking fee, telegraphic transfer fee and the account fee. All in all, admin costs for a mortgage application can cost around £1,000.
To get a mortgage of any amount - £550k or otherwise - you will usually need to put down a deposit of 5% of the property's value. Anything less than this is extremely rare.
Since 100% LTV mortgages are rare, you are unlikely to be able to borrow the full £550k to buy a house of this value. You will typically need to put down a deposit of at least 5% of the purchase price, which in this case would amount to a minimum of £27,500.
This means you would need to take out a mortgage of £522,500.
Many professionals borrowing at this level rely on performance bonuses. Most lenders will take an average of your last two years of bonus income and use 50% to 100% of that figure toward your affordability calculation. This can be vital if your base salary alone doesn't meet the typical 4.5x income multiple.
