Bond Repayment Calculator

How it works
Banks charge interest on the balance each month, so the calculator uses the standard home loan formula with interest compounded monthly over the full term.
Early repayments are mostly interest, and later ones mostly pay off the loan. Paying a little extra each month can shorten the term and cut the total interest considerably.

Questions
What interest rate should I use?
Home loans are usually quoted relative to the prime lending rate, which is 10.75% as of 23 September 2026. Your bank may offer you prime, or a little above or below it, depending on your credit profile and deposit.
Does this include bond and transfer costs?
No. It shows the monthly repayment on the loan only. Bond registration, transfer duty and attorney fees are paid up front and come on top.
Is this financial advice?
No. It’s an estimate to help you plan. Your bank’s quote is the figure to rely on, and a qualified adviser can help with your own situation.
