Work out your monthly mortgage payments

Whether you’re a first- time buyer or looking to remortgage, our mortgage repayment calculator shows you how much your future monthly repayments could be.

To get a better idea of what monthly payments on a new mortgage deal might look like, we suggest using the lower introductory or ‘initial’ rate offered by a lender. That’s because a lender’s Standard Mortgage Rate (SMR) or Standard Variable Rate (SVR) is often higher.

Please note… the information provided is for illustrative use only. To get a more detailed view of monthly payments please use our mortgage partner Koodoo's comparison service.

Answer just 8 questions, and our mortgage partner Koodoo will search the whole of the UK market to show you deals on offer. Alongside monthly payments, we show you the introductory or initial rate, product fees and the Annual Percentage Rate of Charge (APRC). The APRC is the total cost of the mortgage shown as an annual percentage. All lenders calculate APRC in the same way to make comparing mortgage deals easier.

How are monthly mortgage payments calculated?

To work out the monthly payments, we look at how much your new or outstanding mortgage is, the term of the mortgage and the interest rate of the deal you’re looking at.
