Choosing 15 years instead of 30 years
Monthly repayment rises by $1,460 ($5,096/mo vs $3,636/mo), but total interest falls by $391,738 in this model.
Shorter term
Higher monthly repayment, less lifetime interest, own the home sooner if you keep to schedule.
30-year default
Lowest scheduled repayment on paper — useful for cashflow, but more interest if you never pay ahead.
40-year option
Some lenders offer extended terms to reduce instalments; total interest rises sharply. Check product availability.
Unsure which term fits your budget and borrowing capacity? A broker can compare lender policy — not just the calculator maths.
Speak to a brokerGeneral information only. These calculators provide estimates based on the numbers you enter. They do not constitute credit advice, take your full situation into account, or replace a lender's assessment. Fees, eligibility, and actual offers vary. Speak with a broker for guidance tailored to you.

About loan terms in Australia
Why loan term matters more than the rate alone
Two borrowers with the same rate can pay wildly different lifetime interest if one chooses a 25-year term and another stretches to 30 or 40 years. The monthly figure on your bank app is only half the story — the term sets how long interest compounds against the balance.
Refinancing? Watch the term reset trap — a lower rate on a fresh 30-year term can cost more than keeping your remaining term. For payoff levers after you pick a term, try the pay-off-faster playground.
