The exact amount you could save depends on how your mortgage provider calculates interest. The calculation is made with the following assumptions:

  • Your interest rate stays the same for the rest of your mortgage term
  • You don't borrow more money through your mortgage
  • You don't miss any mortgage payments or take a payment holiday
  • You aren't charged any fees, e.g. early repayment charges
  • You don't make any repayments apart from the ones you specified
  • You have a repayment mortgage, not interest only
