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 log in, and we'll automatically complete the information for you. Note the ability to log in is only available on desktop and not mobile devices.
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, Relay UK - 18001 0345 30 20 190. Lines are open Monday to Friday 8am - 8pm, Saturday 9am - 4pm (excluding public holidays). Calls may be recorded.
