How Often Should You Refinance Your Home Loan?
Many homeowners still miss out on thousands in savings simply because they don’t review their home loan often enough.
You may assume refinancing is a one-time thing. It’s not. The truth is, the best time to refinance is when your financial goals or market conditions change, and not reviewing your loan regularly can cost you big time.
If you’re unsure about how often you should refinance your Australian home loan, this guide is for you. You’ll learn when, why and how often refinancing makes sense.
Is There a Rule for How Often You Can Refinance?
There is no official rule in Australia that limits how often you can refinance your home loan.
However, most lenders expect you to have held your current mortgage for at least 6 to 12 months before switching. This isn’t a legal requirement; it’s just common practice to ensure the new loan is worth the change.
Refinancing too early can lead to higher upfront costs, including break fees (especially on fixed rates), discharge fees, and new loan setup charges. You may also need to maintain a certain loan-to-value ratio (LVR), generally under 80%, to access the best refinance rates.
So, while you can technically refinance whenever you like, the question is: should you refinance your mortgage? Let’s explore this further below.
How Soon Can You Refinance a Home Loan in Australia?
Most lenders in Australia allow refinancing after at least six months.
This is often enough time to demonstrate stability, build some equity, or show improved finances. If your income has gone up, your credit score has improved, or your property has increased in value, you may qualify for a better deal sooner than you think.
However, if you’re currently on a fixed rate, refinancing early may trigger break costs, which can run into the thousands. Before moving, always ask your lender for a discharge quote and check potential penalties.
If your reason to refinance is to borrow more (equity release refinance), lenders may want at least 6-12 months of repayment history on your current loan.
Can You Refinance Multiple Times?
Yes—there’s no limit to how many times you can refinance a home loan in Australia.
In fact, some Aussie homeowners refinance every 2 to 3 years to stay ahead of rising interest rates or unlock better features, like offset accounts or interest-only periods.
But be cautious. Refinancing too often can lead to:
- Repeated credit checks, which may impact your credit score
- Valuation and application fees stacking up
- Time and effort gathering documents, submitting applications, and settling new loans
👉Tip: Ensure that each refinance delivers clear value, whether it’s a better rate, more flexible terms, or access to equity.

How Often Should You Refinance Your Home Loan? Find the Right Timing
A good rule of thumb? Review your home loan every 1 to 2 years, or whenever your circumstances change.
If rates have dropped, your fixed term is ending, or you’ve built equity, it’s time to consider a refinance. But there’s no one-size-fits-all timing. It depends on your goals, loan type and market trends.
Even small changes, like shaving off 0.25% from your rate, can lead to big long-term savings. Think of refinancing like a financial health check: essential, recurring, and low-effort with the right advice.

How to Calculate if Refinancing is Worth the Costs
Don’t just look at the rate. You need to crunch the numbers.
Refinancing comes with fees: application, settlement, exit and break costs. If these eat up your savings, it may not be worth it. So, always calculate before you act.
Weigh Potential Savings Against Refinancing Costs
Start by reviewing your existing loan terms and stacking them side-by-side with the offer from the new lender. Focus on the following:
Total Interest Savings Over the Life of the Loan
This gives you a long-term view of what you’ll actually save.
Monthly Repayment Difference
Even a $100/month difference can add up to thousands over time.
Upfront and Switching Costs
These include:
- Application fees (charged by the new lender)
- Discharge fees (charged by your current lender)
- Settlement and legal fees (if applicable)
- Break costs (if you’re exiting a fixed-rate loan early)
If the potential savings far exceed the costs, and you’re not planning to sell or refinance again soon, it’s usually worth making the switch.
Use a Refinance Calculator
Not sure if refinancing will pay off? Let the numbers do the talking.
A general rule of thumb is: if you can lower your interest rate by 0.5% or more, it’s worth running the numbers.
A refinance calculator helps you:
- Compare your current loan and the new one side-by-side
- Estimate monthly repayment changes
- Calculate the total interest saved or paid over time
- Factor in switching fees so you can see the true break-even point
Most Australian banks and comparison websites offer free tools to help with this.

Look Beyond Just the Interest Rate (See Comparison Rate)
Don’t be fooled by a low interest rate alone—it’s only part of the picture.
To understand the real cost of a home loan, you need to look at the comparison rate. This figure combines the advertised interest rate with most associated fees and charges, such as setup fees, ongoing account fees, and discharge costs, and presents it as a single percentage.
That’s why two loans with identical interest rates can have very different comparison rates. One may be weighed down by hidden fees while the other is far more transparent and cost-effective. By comparing both the interest rate and the comparison rate, you get a clearer sense of which loan offers better long-term value.
Think of the comparison rate as your financial truth-teller; it cuts through the marketing and shows you what you’re signing up for.
Strategies for Timing Your Refinance Right
Refinance timing isn’t just about interest rates. It’s about being strategic with your financial position.
To make your refinance work for you, consider these key timing strategies and tips for refinancing:
Refinance When You’re Financially Strong
Lenders look favourably on borrowers with stable employment, consistent income, and good credit history. This can help you secure a better deal and avoid unnecessary conditions.
Act Before Your Fixed Rate Ends
Don’t wait for your loan to revert to a higher variable rate. Start comparing options at least 2–3 months before your fixed term expires.
Plan Ahead of Expected Rate Rises
If rate hikes are on the horizon, locking in a competitive fixed rate early can protect you from higher repayments.
Watch Your Property Value
If your home’s value has gone up, your LVR (loan-to-value ratio) may drop below 80%, opening up access to better interest rates with no LMI (Lenders Mortgage Insurance).
Review Your Loan Regularly
Set a reminder to review your mortgage every 12–24 months, even if you don’t end up switching. Awareness gives you leverage.
Use Comparison Rate
The comparison rate includes hidden fees and the true cost. It helps you compare apples with apples.

When Refinancing May NOT Be the Best Option for You
Refinancing isn’t always the right move.
You may want to hold off if:
- You’re locked into a low fixed rate that’s still better than current market rates
- You’re planning to sell your property soon, and won’t benefit from long-term savings
- You have a small loan balance, where the fees of switching outweigh the interest savings
- Your credit score has dropped or your income isn’t stable, making it harder to get approved or access top-tier rates
In these cases, staying put or choosing a lower-friction option like repricing may be the smarter path.
Alternatives to Refinancing: Repricing or Home Loan Top Up
Refinancing isn’t your only move. There are ways to improve your loan or unlock extra funds, without switching lenders.
Let’s look at two key alternatives: repricing and home loan top-ups.
Negotiate a Better Rate With Your Current Lender With Repricing
Repricing means staying with your lender, but asking for a better rate.
If you’ve found a more competitive rate elsewhere, bring it to your bank. Lenders don’t want to lose your business; many will match or beat a better deal to keep you. Repricing can save you thousands, without the exit fees, paperwork, or loan settlement delays that come with refinancing.
👉Tip: Always ask for the new rate’s comparison rate and ensure it doesn’t come with new hidden fees.
Use a Home Loan Top Up
A home loan top-up lets you borrow extra money against your current home loan, using your available equity.
This option is popular for renovations, investments, or consolidating high-interest debts. It’s generally faster and cheaper than refinancing, but be mindful: you’re increasing your total debt. You’ll need to check:
- How much equity you have
- The interest rate on the top-up portion
- Whether it extends your loan term
Top-ups can be helpful if you qualify and need funds quickly, but only if the purpose makes financial sense.

The Refinancing Timeline and Process in Australia

Here’s what the refinancing timeline typically looks like:
- Research and compare loans (2-3 days)
- Apply and submit documents (2-5 days)
- Conditional approval (1-3 days)

- Unconditional approval (1-3 days)
- Settlement and switching (5-10 days)
