25 vs. 30 Year Home Loans in Australia: Which Term is Best?
Last updated 2026-06-27 · Published 2026-06-27
Compare 25-year and 30-year home loan terms in Australia. Weigh the pros of lower monthly repayments against the costs of paying more interest over the long run.
Standard Loan Terms in the Australian Market
When you apply for a home loan in Australia, the standard terms offered by banks are 25 years and 30 years. The 30-year term is by far the most popular choice because it spreads repayment over a longer time, reducing monthly commitments.
However, choosing a shorter 25-year term is one of the most effective ways to save money, provided your budget can comfortably support the higher monthly payments.
Repayment Differences vs. Interest Savings
A 30-year home loan will have the lowest monthly repayments, making it easier to qualify for a loan and manage your monthly cashflow.
On the other hand, a 25-year term increases your monthly payments by about 10% to 15%, but it reduces the life of the loan by five full years. This prevents interest from compounding over those five years and saves you tens of thousands of dollars in interest charges.
How to Shorten a 30-Year Loan Manually
If you want the flexibility of a 30-year loan but want to avoid the high interest costs, you can choose a 30-year term and make extra repayments or use an offset account.
A 100% offset account offsets your savings against your home loan balance. Every dollar in your offset account reduces the interest charged, effectively shortening your loan term and saving interest while keeping your cash liquid.

Can I change my home loan term from 30 to 25 years later?
Yes, you can do this by renegotiating with your current lender, refinancing to a new loan with a shorter term, or simply making extra payments so that your loan is paid off in 25 years.
Is a 30-year home loan always the best choice for first-time buyers?
Not always, but it is often chosen because it maximizes borrowing capacity and offers safety through lower mandatory monthly payments. Buyers can then make extra payments voluntarily.
