See how much you could save Mortgage overpayment calculator

Our simple calculator below will give you an indication of how much interest you could save or how much sooner you could pay off your mortgage by making extra payments.

Is there a limit to how much I can overpay?

  • If you are on standard variable rate, a flexible variable rate or a tracker rate there is no limit on the amount you can overpay.
  • If you are on a fixed rate an early repayment charge is due if you repay all or part of your mortgage before the end of the set fixed period. The charge is 3% of the amount repaid, however you can make an overpayment of up to £1,000 each year without any penalty.
