Mortgage overpayment calculator

What are your options?

Before using the overpayment calculator, take a look at your options for making an overpayment.

One-off overpayment

  • This is an additional payment that you can make at any time.
  • You can make one-off overpayments as often as you like, but if you exceed your overpayment allowance, you’ll have to pay an Early Repayment Charge (ERC) on the amount over 20%.   
  • If you pay £1,000 or more, your monthly payment will be recalculated.
  • If you want to pay off your mortgage or you have less than £500 remaining, you’ll need to request a redemption statement by logging in to Manage your Mortgage

Regular overpayment           

  • This is a regular payment you make every month on top of your monthly Direct Debit.
  • You must continue to make your normal mortgage payment in full each calendar month.
  • If you pay more than 20% of your outstanding balance, we’ll cancel your regular overpayment so that you don’t pay an ERC.
  • Monthly overpayments will reduce your mortgage balance and could help save you interest.
  • You can set-up, amend, or cancel your regular overpayment by logging in to Manage your Mortgage.

Deciding how much to overpay            

  • If you’re on a fixed or tracker rate product, you can pay up to 20% of your outstanding balance for each of your sub-accounts before an ERC will apply. If you exceed your allowance, you’ll have to pay an ERC on the amount over 20%. To find out what this means for you, log in to Manage your Mortgage.
  • If you’re on our Standard Variable Rate (SVR), there’s no limit to how much you can overpay, and there’s no ERC.

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.
