Offsetting calculator

For existing Offset Mortgage customers only

With an Offset Mortgage we take your savings into account when working out your interest. Say you have a mortgage of £100k and £20k in savings. You only pay interest on the difference – which in this case is £80k. Enter your details below to see how much your Offset Mortgage could save you in interest payments.

Our offsetting calculator can give you an idea of the benefits of using your credit balances against your mortgage. The figures provided are for indication purposes only.

How we calculate these savings

  • the calculator assumes your interest rate will stay the same for the term of your mortgage
  • we’ve evened out the months so they’re all the same length – 30.4 days each – so monthly interest will be consistent
  • repayments are rounded up or down to the nearest pound
  • we’ve rounded time saved down to the closest month
  • interest is calculated daily and added monthly
  • interest saved is rounded up or down to the nearest pound
  • the calculator assumes the total savings balance is held in a linked account(s) and remains constant throughout the term of the mortgage
  • if your total savings increase or decrease on an adhoc basis, your monthly interest payments will also change respectively.
