Modelled, indicative repayments for loan amounts from $400,000 to $1,500,000, at 6.5% (as of 9 August 2026), over 25 and 30-year terms — plus how much an extra $200 a month saves in interest and time. Not a loan offer or a pre-approval.

Every repayment on this page is modelled at 6.5% over the term shown, using a level-repayment amortisation — the standard structure of an Australian principal-and-interest home loan, where each repayment covers the interest accrued since the last one and whatever is left reduces the balance.
Early on, most of a repayment is interest, because interest is charged on a balance that has barely moved. That reverses slowly over the life of the loan, which is why the total interest on a 30-year term is so much larger than on a 25-year term for the same amount borrowed.
These are indicative figures for comparison, not a loan offer, a pre-approval or a quote. A lender assesses your income, expenses, credit history and the property itself, and the rate you are offered will differ from the one modelled here.
No. The loan amount is what you borrow, which is the purchase price less your deposit, so match the figure on this page to the loan rather than to what you are paying for the property. The amounts published here run from $400,000 to $1,500,000.
Open any card to see both terms side by side. Interest is charged on the outstanding balance every month, and a 30-year loan carries a higher balance for longer. The monthly repayment is lower, but you make sixty more of them and each of the early ones repays less principal.
They are modelled at a single fixed rate of 6.5% and take no account of fees, insurance or rate movements, so treat them as a comparison between loan sizes rather than a budget. Use the full mortgage calculator with your own rate, term and deposit for anything you plan to act on.
The repayment on a variable loan changes with the rate; the term usually stays the same unless you ask your lender to adjust it. On a fixed loan nothing changes until the fixed period ends, at which point the loan reverts to a variable rate and the repayment resets.

This calculator exists to show you the arithmetic. It applies published Australian rates, thresholds and formulas to the numbers you enter and shows the working, so you can check it. That is all it does — it produces a number and describes what the number is. It does not recommend anything and it holds no opinion about any financial product.
