Important information

If you're not on our Standard Variable Rate (which has no restrictions on the amount you can overpay), there may be a maximum amount you can overpay each year without incurring an Early Repayment Charge. If you need more information please refer to your most recent mortgage offer. 

To calculate your potential savings, we’ve made the following assumptions:

  • The amount you currently pay is based on the information you've entered.  
  • You’ll make the same monthly overpayments for the whole of your mortgage term.
  • The interest rate will remain the same for the term of the mortgage.
  • Months are 12 equal lengths so the monthly interest won't change.
  • Repayment amounts are rounded up or down to the nearest £1 for display purposes.
  • The potential reduction in time to repay your mortgage is presented as years/months. The figure is rounded up or down accordingly for display purposes.

This calculator should be used as a guide only. It won’t give you a definite figure of how much interest or time you could save paying back your mortgage. It also doesn’t take into account any charges for early repayments and is based on a capital repayment mortgage only. It doesn’t include all the information you need to compare mortgages, so please ask for a mortgage illustration before choosing a mortgage.

 

Your home or property may be repossessed if you do not keep up repayments on your mortgage.
