Change your interest rate calculator

Work out how much your payment would be if your mortgage interest rate went up or down.

You’ll find the details you need in your hub or on your mortgage statement.

This calculator is just a guide to give you an idea of what your mortgage payment would be. We’ve made the following assumptions about your mortgage:

  • Calculations are based on a repayment (capital and interest) mortgage
  • Any regular overpayments remain the same for the term of the mortgage
  • Interest is calculated daily and added monthly
  • There is no change in interest rate that would recalculate your monthly payments
  • There are no other changes to your mortgage which may impact your monthly payment such as changes to your fixed rate period, mortgage type, overpayments made during your mortgage term
  • If you have different accounts that make up your mortgage, they must be calculated individually
