Nearly half of refinancers reset to 30 years — the hidden cost on your home loan (Australia 2026)

Full breakdown + calculator: This article supports the term reset trap calculator on the refinance hub — run your balance before you sign anything.

If you have seen the short-form videos about a “$250,000 refinance mistake”, this is the mechanism behind many of them: not a bad rate — a longer clock.

What the survey found

Finance comparison site Money.com.au reported survey findings (widely covered in Australian broker media, including Mortgage Professional Australia) that:

These are survey self-reports, not APRA statistics — but they match what brokers see daily: a sharper headline rate paired with a fresh 30-year amortisation schedule, even when the borrower only had 22 or 25 years left.

General information only — your loan contract and lender disclosure pack are the source of truth for your file.

Why a lower repayment is not always a “win”

When you refinance, two levers move at once:

1. Interest rate — can fall (good for total interest if the term stays the same).
2. Loan term — if reset to 30 years, the minimum repayment falls because you spread the balance over more years.

Lenders and comparison sites often lead with the new minimum repayment. That number can look like a saving even when lifetime interest rises sharply.

Worked example (illustrative)

Money.com.au’s published analysis (via MPA) modelled a $600,000 loan with 25 years remaining at 5.70%, refinanced to 5.50% but extended to 30 years:

• Monthly repayment: about $349 lower
• Extra total interest vs keeping 25 years at the new rate: about $121,000

On larger balances — $700,000–$800,000 common in Sydney and Melbourne corridors — the gap can approach $200,000–$250,000 when you combine a rate improvement with an 8-year term extension (e.g. 22 years left → 30-year reset).

Run your numbers in the term reset trap calculator (live on the refinance hub). Defaults load a six-figure trap example; change balance and rates as you type.

Match-term vs reset — the comparison to insist on

Before you accept any refinance offer, ask for two repayment schedules:

The gap between those two paths is the term reset trap — extra interest you pay for a lower minimum repayment.

Our hub calculator shows:

• Your loan now — current rate and remaining term
• Match term — fair comparison at the new rate
• Reset term — what the “cheaper” monthly repayment actually costs in total interest

When extending the term can be deliberate strategy

Extending is not always wrong — but it should be conscious, not accidental.

Situations where a longer term is sometimes discussed with a broker:

• Short-term cash-flow relief with a written plan to revert to higher repayments when income recovers
• Debt restructuring where total household cost and security structure are modelled holistically — see debt consolidation pathways
• Investment property transitions where tax and cash-flow planning is part of the file (requires qualified tax advice separate from credit assistance)

The survey’s concern is borrowers who thought they were only getting a rate improvement — not 8 extra years of interest.

Checklist before you sign

1. Years remaining — confirm in writing (not “original 30-year loan from 2018”).
2. Two total-interest figures — match-term vs 30-year reset at the offered rate.
3. Switching costs — discharge, government fees, break costs if fixed — model break-even in the refinance playground.
4. Retention vs switch — if your gap is modest, a retention call may beat switching; if the gap is wide, external refinance may pay back faster — see loyalty tax.
5. Do not sign on minimum repayment alone — compare total interest and years to debt-free.
