    Making overpayments
    If you made overpayments you will pay off the mortgage sooner and pay less interest.

    Interest Rates
    The interest rate for the mortgage depends on the deposit you make for the property. By making a 10% deposit the Loan to Value (LTV) will be 90% and a 30% deposit means an LTV of 70%. The higher the deposit the lower the interest rate per month and the lower the total interest paid at the end of the mortgage

    The calculator assumes the interest remains the same for the term selected. However, the interest rate could be higher in the future and this would increase the cost of the mortgage. For a new mortgage deal have a look at our Mortgage Best Buys.

    Term in years
    The longer the term the lower the monthly costs although the total amount of interest you pay will be higher. The longest mortgage from lenders is 40 years although you can select shorter terms such as the usual 25 years or less which would reduce the total interest paid for the mortgage.

    Many lenders allow you to make overpayments of up to 10% of the outstanding balance each year. The calculator shows you how much you can save in interest and how many years of repayments you can save if your mortgage ends early.

    Enter the monthly amount of overpayment you wish to make, and you can also enter a single lump sum payment. Tell us when you intend to apply this single payment in the future (number of months) such as 18 months or 34 months time and so on.
