Frequently asked questions

How are loan repayments calculated in Australia?
Most Australian loans use an amortisation formula that splits each repayment into principal and interest portions. The monthly repayment depends on the loan amount, interest rate, and loan term. Early repayments are mostly interest, shifting toward principal over time.
What is the difference between a fixed and variable rate loan?
A fixed rate locks your interest rate for a set period (typically 1-5 years), giving predictable repayments. A variable rate moves with the market, meaning repayments can go up or down. Many Australian borrowers split their loan between both to balance certainty and flexibility.
How much can I borrow for a home loan in Australia?
There is no universal income multiple. Lenders assess income, living expenses, existing debts, deposit size and other commitments, and APRA-regulated banks must apply at least a 3 percentage point serviceability buffer above the loan rate. Use the borrowing power result as a scenario, not an approval estimate.
Does HECS/HELP debt affect my borrowing power?
Yes. Lenders include your HECS/HELP compulsory repayment as a liability when assessing how much you can borrow. The higher your income, the larger the repayment percentage, which reduces the amount a lender will offer you.
What fees should I watch for when taking out a loan?
Common fees include application or establishment fees, ongoing monthly or annual fees, missed-payment costs, fixed-rate break costs, and valuation fees for property loans. A comparison rate includes interest and most fees, but it is based on a standard example and may not reflect your amount, term, balloon payment or every charge.
