Mortgage overpayment calculator
Our simple calculator will show you whether you could repay your mortgage faster, or reduce the amount you pay each month, by making either regular monthly overpayments or a larger lump sum overpayment.
You can either fill the calculator out manually, or for a more personalised (and potentially more accurate) result, you can sign in, and we'll automatically complete the information for you.
You can find further information on making overpayments below the calculator. If you would prefer to chat to someone about your overpayment options, please contact us on: 0345 30 20 190, Minicom number 0800 917 0526. Lines are open Monday to Friday 8am - 8pm, Saturday 9am - 4pm (excluding public holidays). Calls may be recorded.
