How much could you save by refinancing to a lower rate?

Refinancing your mortgage can be a powerful strategy to reduce your monthly repayments and overall loan cost. By securing a lower interest rate, you can potentially save thousands over the life of your loan.  

Let's explore how refinancing works, the potential savings, and how Aussie can assist you in this journey. 

Understanding mortgage refinancing 

What is refinancing? 

Refinancing involves replacing your existing mortgage with a new one, typically with better terms or a lower interest rate. This process pays off your current loan and establishes a new loan agreement, which can lead to reduced monthly payments and less interest paid over time. 

Why consider refinancing now? 

As of August 2025, the Reserve Bank of Australia (RBA) has reduced the official cash rate by 0.25%, bringing it down to 3.60%. This decrease could prompt many lenders to lower their interest rates, making it an opportune time for homeowners to consider refinancing.

Calculating potential savings 

Using a refinancing savings calculator 

To determine how much you could save, it's essential to compare your current loan with potential new options. Aussie offers a Mortgage Repayment Calculator that allows you to input your loan details and see how different interest rates and terms can affect your repayments.

Factors influencing savings 

Several elements impact the amount you can save through refinancing: 

  • Current interest rate vs. new rate: the difference between your existing rate and the new rate plays a significant role. Even a small reduction can lead to substantial savings over time. 

  • Loan amount: the larger your outstanding loan balance, the more you stand to save with a lower interest rate. 

  • Remaining loan term: refinancing can adjust your loan term, either shortening it to pay off your mortgage faster or extending it for lower monthly payments. 

  • Fees and costs: it's crucial to consider any fees associated with refinancing, such as exit fees from your current loan and establishment fees for the new loan. Ensure that the savings outweigh these costs.

Benefits of refinancing 

Beyond reducing your monthly repayments, refinancing offers several advantages: 

  • Reduced interest payments: lowering your interest rate means you'll pay less interest over the life of the loan. 

  • Shorter loan term: you can choose to refinance to a shorter loan term, helping you pay off your mortgage faster. 

  • Access to equity: refinancing can allow you to access the equity in your home for other financial needs, such as home improvements or debt consolidation.
