Using your savings on your offset mortgage allows you to take advantage of the lower payment straight away. If you withdraw from the offset savings account, you will need to ask us for your payments to be recalculated otherwise you could potentially be over/underpaying

Please note

The calculations used in the demonstrator are for illustration purposes only and assume the following:

  • The interest rate will remain the same throughout the term of the mortgage - our actual mortgage rates available are dependent on market conditions so change from time to time.
  • Requires a static (i.e. fixed) payment to be set up and maintained throughout the mortgage term.
  • The mortgage repayment method is capital and interest.
  • No interest is payable on the Offset savings balance.
  • Regular monthly savings deposits are made throughout the mortgage term (in line with the 'Monthly Savings Deposit' entered), or a constant savings balance is maintained (in line with the 'Current Savings Balance' entered).
  • You make a lump sum deposit into your linked Offset savings account of the amount specified above and that you maintain this balance.
  • The example used on this page assumes that basic and higher rate tax payers do not pay tax on their savings and that additional rate taxpayers pay 45% tax on savings interest and are based on current HM Revenue and Customs rules which are subject to change. Customer usage of any applicable Personal Savings Allowance is not included within these calculations.
  • *AER stands for Annual Equivalent Rate and shows you what the interest rate would be if interest was paid and added each year. This will enable you to compare more easily the return you can expect from your savings over time.
  • Fee calculations are not included within the offset calculator and must be taken into account separately
