Principal and Interest Calculator

It’s important to understand how each of your home loan repayments will start to reduce the balance of your home loan. 

With the interest on your loan being calculated daily, every payment counts. The more you can reduce both the principal and the interest the better off you will be in the long run.

Find out how much of your repayment goes towards reducing the principal and how much interest payable on your home loan.


Calculations are estimates provided as a guide only based on information you provided. They assume interest rates do not change throughout the loan. This calculator is not intended to be your sole source of information when making a financial decision. You may wish to consider getting advice from a licensed finance professional. Fees and charges are payable. The calculations do not take into account fees, charges or other amounts that may be charged to your loan (such as establishment or monthly service fees or stamp duty). If you are borrowing more than 80% of the value of the property, Lenders Mortgage Insurance may apply. Any of these additional amounts will increase repayments under the loan. Calculations are not a loan approval. Applications are subject to credit approval, satisfactory security and minimum deposit requirements. Conditions apply to all loan options. Full terms and conditions will be set out in our loan offer, if an offer is made.
