Mortgage overpayment calculator

See how making overpayments on your mortgage could save you money by reducing your mortgage term or the amount of interest charged.

The mortgage will be secured on your home. Your home may be repossessed if you do not keep up repayments on your mortgage.

This mortgage calculator is for illustrative purposes only. It provides an estimate of overpayment effects against your current interest rate. Please note the calculator does not factor in any early repayment charges.
