Frequently asked questions
Our repayment calculator takes into account how much you need to borrow, the loan term (for example 30 years), and then calculates the interest charge based on which loan structure you choose.
From there, it can work out based on the loan principal plus the interest what the total figure it is you need to pay over the loan term.
For example, if you borrowed $500,000, and your total interest charge was $350,000 over 30 years, then the total amount payable would be $850,000. This is divided by the total months in your loan term to get to your monthly repayment amount. If interest rates change, or your loan type changes – say from variable to fixed – or if you have a feature such as an offset account, our system will keep track of these changes and update the monthly direct debit.
Keep in mind that there may be fees and other charges added to the total payable amount, such as Lenders Mortgage Insurance.

*An automated valuation model estimate (AVM Estimate) is a statistically derived estimate of the value of the subject property. An AVM Estimate is generated (i) by a computer driven mathematical model in reliance on available data; (ii) without the physical inspection of the subject property; (iii) without taking into account any market conditions (including building, planning, or economic), and/or (iv) without identifying observable features or risks (including adverse environmental issues, state of repair, improvements, renovations, aesthetics, views or aspect) which may, together or separately, affect the value. An AVM Estimate is current only at the date of publication or supply. An AVM Estimate must not be relied upon as a professional valuation or an accurate representation of the market value of the subject property as determined by a valuer. CoreLogic expressly excludes any warranties and representations that an AVM Estimate is an accurate representation as to the market value of the subject property. To the full extent permitted by law, CoreLogic excludes all liability for any loss or damage howsoever arising or suffered by the recipient, whether as a result of the recipient's reliance on the accuracy of an AVM Estimate or otherwise arising in connection with an AVM Estimate.
