        How this calculator works

        Unlike most mortgage repayment calculators, this one allows you to work out the monthly cost of a part-and-part mortgage. Simply enter the monetary amount of your mortgage that will be interest-only and the portion that will be repayment, along with the term length and interest rate, and the tool will do the rest.

        The results will break down the total capital repayments and interest payments you’ll be making each month, as well as reveal the grand total of these two amounts.

         What are the benefits of it?

        Aside from being specially designed for people with, or interested in, part-and-part mortgages, there are a number of benefits to using this calculator to work out your repayments, such as…

        • The calculations can give you a rough idea of the mortgage you’d get before you start the application process.
        • They can help you plan ahead and budget.
        • You can compare the results to repayment figures for other mortgage types, such as interest-only and capital repayment.

        Although this mortgage calculator is a great starting point, the limitations of all online mortgage calculators apply. The results it returns will not be bespoke to you and the deals you qualify for might come with higher or lower repayments than these.
