  • The calculator is not intended to be your sole source of information when making a financial decision. Consider getting advice from a licensed finance professional, if you need it.

  • It does not consider your ability to make the repayments shown.
  • To help you consider interest rate changes, you can explore the effect of a higher or lower interest rate on your repayments.
