What Are the Real Savings When You Refinance?

Refinancing your home loan can reduce your interest costs by several thousand dollars each year if your current rate sits above what lenders are offering to new borrowers.

The decision to refinance centres on whether the gap between your current rate and available rates justifies the cost and effort of switching. For many Brisbane homeowners, that gap has widened since their fixed rate period ended or their lender quietly stopped discounting their variable rate. The question is whether refinancing delivers enough of a saving to make the application process worthwhile.

How Much Can You Actually Save?

Your potential saving depends on the difference between your current interest rate and the rate you can access through refinancing. A reduction of 0.5% on a loan amount of $500,000 saves roughly $2,500 per year in interest. A reduction of 1% saves close to $5,000 annually.

Those figures assume you're on a standard variable rate that hasn't been reviewed in some time. In our experience, clients who refinance after their fixed rate period ends often see reductions closer to 1% or more, particularly if their lender reverted them to a higher standard variable rate without offering a retention discount. The saving compounds over time, so even a modest rate reduction adds up across the life of the loan.

When Refinancing Makes Sense in Brisbane

Refinancing becomes worthwhile when the interest you'll save over the next two to three years exceeds the cost of switching.

Consider a homeowner in The Gap with a loan amount of $600,000 on a variable interest rate of 6.3%. If they can access a lower interest rate of 5.8% by refinancing, the annual saving is around $3,000. Application and valuation costs typically sit between $1,000 and $1,500, meaning the saving covers the cost within six months. After that, the reduction flows directly into their repayments or offset account.

Timing matters in Brisbane's property market. Suburbs like Paddington, New Farm, and Ascot have seen strong property valuation growth in recent years, which can increase your equity position and improve the rate you're offered. If your property has gained value since purchase, refinancing may also allow you to remove lender's mortgage insurance if you've crossed the 80% loan-to-value threshold.

Does Refinancing Always Involve Switching Lenders?

Not necessarily. Some lenders will adjust your rate if you request a loan health check and threaten to leave, though the discount they offer is often less generous than what you'd receive as a new customer elsewhere.

Internal refinancing, sometimes called a loan restructure, can improve your loan features without the full application process. You might add an offset account, adjust your repayment frequency, or consolidate debt into your mortgage. However, if your goal is to reduce your interest rate substantially, switching lenders usually delivers the largest saving. Loyalty doesn't tend to be rewarded in mortgage pricing.

What About Equity Release?

Refinancing also lets you access equity in your property for other purposes, such as funding an investment property deposit, renovations, or debt consolidation.

Brisbane homeowners in suburbs like Bulimba, Hamilton, and Wilston have benefited from solid capital growth, which increases the equity available to unlock. If your property has appreciated and your loan-to-value ratio has dropped, you can release equity without needing to sell. This approach works particularly well for buyers looking to enter the investment market without saving a separate deposit.

Keep in mind that accessing equity increases your loan amount, which raises your interest costs over time. The decision should be based on whether the purpose, such as purchasing an income-producing asset, justifies the additional borrowing.

Should You Switch to Fixed or Stay Variable?

The choice between fixed and variable rates depends on your tolerance for rate movements and how long you plan to hold the loan.

A fixed interest rate locks in your repayments for a set period, usually between one and five years. If you value certainty and expect rates to rise, fixing can protect your cashflow. A variable interest rate gives you flexibility to make extra repayments, use redraw or offset features, and benefit from rate cuts if they occur.

Many clients we work with in Brisbane choose a split structure, fixing part of the loan for stability while keeping the rest variable for flexibility. This approach limits your exposure to rate increases without locking you into a fixed rate that might become uncompetitive if the market shifts. The proportion you fix should reflect your financial priorities, not just current rate predictions.

How the Refinance Process Actually Works

The refinance application follows a similar path to your original home loan application. You'll submit income verification, recent loan statements, and details of your current property.

Most lenders require a property valuation, either desktop or physical, to confirm your equity position. The valuation fee is usually between $200 and $400. If your loan-to-value ratio is above 80%, you may also need to account for lender's mortgage insurance, though this is less common when refinancing an existing property with strong equity.

Settlement typically takes between four and six weeks from application to drawdown. During that time, your new lender will handle the payout of your existing loan and register the new mortgage on title. You'll need to budget for discharge fees from your current lender, which are usually around $300 to $500, plus any break costs if you're exiting a fixed rate early.
