TL;DR — Key takeaways
|
One of the most common questions brokers get is not “should I refinance?” but “can I refinance right now?” The answer depends on what kind of loan you’re on, how long you’ve had it, and whether a new lender will accept your application. This guide covers all three.
If you want to understand whether refinancing is worth it financially, read our guide on when to refinance first. This article focuses specifically on timing — when you’re allowed to, and when the timing actually makes sense.
Can you refinance at any time?
For variable rate home loans: yes, you can refinance at any time with no early exit penalty. There is no legal minimum holding period in Australia. If you signed last month and found a better rate today, you can move.
For fixed rate home loans: technically yes, but it comes with a cost. Exiting a fixed rate loan before the fixed period ends triggers a break cost calculated by the lender. In a falling rate environment — like August 2026 — those break costs can be significant, sometimes tens of thousands of dollars on larger loans.
Before you do anything: Call your current lender and ask for the exact break cost figure. This is a mandatory disclosure under Australian credit law. Get it in writing. The number tells you immediately whether early exit makes financial sense.
Fixed vs variable: the timing rules side by side
How does a fixed rate break cost work?
Break costs are calculated by the lender based on the difference between your locked rate and current wholesale interest rates, multiplied by your remaining fixed loan balance and time left. There is no standard formula — each lender calculates differently, and the number can be surprisingly high in a falling rate environment.
Here’s why: if you fixed at 6.5% and rates have since fallen to 5.5%, your lender locked in the margin at 6.5%. Releasing you early means they lose that margin. The break cost compensates them for that loss. The bigger the rate drop and the longer your remaining fixed term, the bigger the break cost.
Your lender must give you a break cost estimate on request at any time — this is a legal requirement under the National Credit Code. Ask for it before engaging any new lender, not after. Use our refinance home loan calculator to see whether the ongoing rate saving outweighs the upfront break cost.
What about the “6-month rule” — is that real?
There is no legal 6-month minimum holding period for refinancing in Australia. However, there are two practical reasons this number comes up.
Lender appetite. Some lenders are reluctant to refinance a loan that was only recently settled. They may view it as a sign of financial instability or poor planning. In practice, most lenders have no hard rule, but if your loan is less than 6 months old you may face more scrutiny on your application.
Your repayment history. New lenders will request 6 months of bank statements and loan statements. If you’ve only held the loan for 2 months, there isn’t much history to assess. Lenders want to see consistent on-time repayments — and that record takes time to build.
If you’re refinancing a loan that’s less than 6 months old, a broker is your best path forward. They know which lenders are flexible and can present your application in the strongest possible way. See how the refinancing process works before you start.
What factors affect whether a new lender will approve you?
Timing isn’t just about your current loan — it’s also about whether a new lender will say yes. Even if you’re legally allowed to refinance, you need to meet the new lender’s serviceability requirements.
