For thousands of Australian homeowners, the end of a fixed rate period represents one of the most significant financial moments of their mortgage life. What happens when the fixed term expires and how you respond can have consequences that play out over many years.

What Happens When Your Fixed Rate Expires?

At the end of your fixed rate term, your loan typically reverts to your lender's standard variable rate, unless you take action to fix again or refinance. This revert rate is rarely the most competitive rate your lender offers, and is often significantly higher than what a new borrower would be offered today.

For many homeowners, the moment of reversion represents the largest overnight increase in their mortgage repayment they've ever experienced, particularly for those who locked in rates below 2% during the COVID period and are now reverting to rates that may be three to five times higher.

How Much Does the Revert Rate Actually Cost?

The difference between a competitive refinanced rate and a lender's standard variable revert rate can be substantial. On a $600,000 loan, even a 0.5% difference in interest rate represents $3,000 per year in additional interest, $30,000 over a decade.

For homeowners on expired fixed rates who have simply accepted the revert rate without reviewing their options, the cumulative overpayment can be significant, money that could instead have been directed to the offset account, additional repayments or personal savings.

Your Options When Your Fixed Rate Ends

When your fixed rate period ends, you have three primary options: refix with your current lender, refinance to a new lender, or move to a variable rate with your current lender.

Option 1: Refix With Your Current Lender

Your existing lender will likely offer you a new fixed rate at the end of your current term. This is the path of least resistance and sometimes the right decision. But it's important to compare what your lender is offering against the broader market before accepting any fixed rate offered.

Option 2: Refinance to a New Lender

Refinancing at the end of a fixed rate period gives you the opportunity to access the most competitive rates and loan features available in the market. It also avoids the break costs that would apply during the fixed term. This is often the moment where the greatest savings are achievable.

Option 3: Move to a Variable Rate With Your Current Lender

If you want flexibility without the complexity of refinancing, moving to a variable rate with your current lender allows you to make additional repayments and use offset facilities. However, you should negotiate the rate rather than simply accepting what you're offered.

The Three-Month Window Before Your Fixed Rate Ends

The most important period is the three months before your fixed rate expires. During this window, you have time to properly compare options, approach lenders, get approval for refinancing if needed and ensure a smooth transition at expiry.

Waiting until the expiry date and finding yourself on the revert rate while scrambling to organise refinancing costs you money every day you delay.

Getting a Home Loan Reset Review Before Your Fixed Rate Ends

A structured home loan review focused on your upcoming fixed rate expiry can identify the best available options for your situation, compare refinancing against refixing against moving variable and give you a clear action plan before the expiry date arrives.

This is one of the highest-value financial conversations you can have and the one most likely to create real, lasting financial breathing space.
