Change your interest rate calculator

If your interest rate were to change, this handy calculator will tell you what your new monthly payment would be.

This calculator is for illustrative purposes only. Please see the assumptions we have made below the calculator.

This calculator is for illustrative purposes only and we’ve made the following assumptions:

  • Based on a repayment mortgage
  • Any regular overpayments remain the same for the term of the mortgage
  • All years are of equal length
  • Interest is calculated daily and added monthly
  • Multiple sub accounts must be calculated individually
  • There is no change in interest rate that would recalculate your monthly payments
  • There will not be any changes to your mortgage which would result in a recalculation of your monthly payment e.g. changes to your product term, type or change of owners.
