The average Australian home loan takes 30 years to pay off. But with the right strategies, many borrowers pay their loan off 5, 10, even 15 years early — saving hundreds of thousands in interest. Here are seven approaches that actually work, with real numbers.
Why Paying Early Makes Such a Big Difference
On a $600,000 home loan at 6.0% over 30 years, you pay $693,949 in total interest — more than the original loan amount. Shave 10 years off that loan and you save approximately $180,000 in interest. The maths rewards early action dramatically.
Strategy 1 — Switch to Fortnightly Repayments
Instead of 12 monthly repayments per year, fortnightly repayments result in 26 half-payments — the equivalent of 13 monthly repayments. You barely notice the difference month to month, but you make one extra full repayment per year.
On a $600k loan at 6%: Switching to fortnightly saves approximately $58,000 in interest and cuts 4 years off the loan term.
Strategy 2 — Make Extra Repayments
Every extra dollar you put into your home loan reduces the principal, which reduces the interest charged the following month. Even small amounts make a significant difference over time.
On a $600k loan at 6%: An extra $500/month saves approximately $148,000 in interest and cuts 8.5 years off the term.
Strategy 3 — Use an Offset Account
An offset account is a transaction account linked to your home loan. The balance offsets your loan principal for interest calculation purposes. If you have $50,000 in your offset account against a $600,000 loan, you only pay interest on $550,000.
$50,000 in offset on a $600k loan at 6%: Saves approximately $78,000 in interest over the life of the loan.
Strategy 4 — Refinance to a Lower Rate
Many Australians are paying significantly more than the best available rate. Refinancing from 6.5% to 5.9% on a $600,000 loan saves approximately $3,600 per year in interest. Over 10 years, that is $36,000 — without paying a cent extra per month.
Strategy 5 — Put Windfalls Straight Into the Loan
Tax refunds, bonuses, inheritance or any unexpected money paid directly into your home loan makes an outsized difference. A $10,000 lump sum early in the loan can save $30,000–$40,000 over the life of the loan due to compounding interest savings.
Strategy 6 — Avoid Interest Rate Increases on Remaining Balance
When rates rise, keep your repayments at the higher amount rather than reducing them when rates fall. Each time rates went up from 2022–2023, borrowers who kept repayments elevated were effectively making extra repayments and reducing principal faster.
Strategy 7 — Review Your Loan Annually
Most lenders quietly revert refinancers to less competitive rates over time. Set a calendar reminder to compare your current rate against the market every 12 months. Even negotiating 0.25% off without refinancing saves thousands.
