A fixed rate locks in your repayment for a set period, typically one to five years. That certainty protects you from rate rises, but it also means you cannot take advantage of rate cuts without paying break costs, and most fixed products limit additional repayments and remove access to offset accounts.
Fixing for Five Years Without Comparing Break Cost Clauses
Most lenders calculate break costs using the difference between your fixed rate and the current wholesale cost of funds for the remaining loan term. A five-year fix locked in during a rate peak can cost tens of thousands of dollars to exit if rates fall. Shorter fixed terms carry lower break costs because the exposure period is reduced.
Consider a buyer who fixes $600,000 for five years at a rate that later sits well above the market. Two years into the term, they need to sell or refinance. The break cost reflects three years of lost interest income to the lender, often calculated using the bank bill swap rate as a reference. That cost can exceed $20,000 in a falling rate environment. The same buyer fixing for two years would face a break cost reflecting only the remaining period at the time of exit.
Some lenders use different break cost formulas or cap the fee at a set number of months' interest. Comparing these clauses before you commit is as important as comparing the advertised rate. We regularly see borrowers choose the lowest rate without reading the break cost schedule, then discover the penalty is structured in a way that eliminates any benefit from refinancing.
Locking in a Rate Without Understanding Portability
Portability allows you to transfer your fixed rate loan to a new property if you sell and buy during the fixed period. Not all lenders offer this feature, and those that do often impose conditions around timing, loan amount, and security type. If your loan is not portable and you sell, you will pay break costs on the full balance.
Buyers moving within Eight Mile Plains or to nearby suburbs such as Runcorn or Underwood often assume they can take their fixed rate with them. If the loan lacks portability and you settle the sale before the fixed term expires, the lender treats it as a discharge and applies the break cost formula. A portable loan gives you the option to avoid that cost by transferring the fixed balance to the new property and topping up with a separate variable or fixed split if you need additional funds.
The portability clause usually requires the new purchase to settle within a set window after the sale, often 60 to 90 days. If the timing does not align, portability becomes unusable. Confirming this feature exists and understanding the conditions attached is particularly relevant for buyers in suburbs close to schools, parks, and the Gateway Motorway, where families often upgrade within the same area as circumstances change.

Ignoring the Comparison Rate on Fixed Products
The comparison rate incorporates the interest rate, ongoing fees, and a portion of upfront costs over a standard loan term and amount. It provides a clearer picture of the total cost than the advertised rate alone. Fixed rate products often carry higher application fees or annual fees than variable products, and those fees can shift the actual cost significantly.
A fixed rate advertised at 5.89% might show a comparison rate of 6.12% once fees are included, while a variable product at 6.09% might have a comparison rate of 6.15%. The gap narrows or reverses depending on fee structure. Buyers who compare only the headline rate may lock in a product that costs more over the fixed period once all fees are accounted for.
Comparison rates are calculated on a $150,000 loan over 25 years, so they are not precise for every borrower. A larger loan amount or shorter term will dilute the impact of upfront fees, while a smaller loan will magnify it. The principle remains useful: read the comparison rate, identify where the gap comes from, and calculate whether the fee load suits your loan size and intended holding period. For buyers considering a home loan in Eight Mile Plains, reviewing both rates before committing avoids paying for features or fees that deliver no value.
Choosing a Fixed Rate During a Refinance Without Reviewing the Exit Timeline
Refinancing onto a fixed rate makes sense if you expect rates to rise and want to lock in current pricing. It stops making sense if your circumstances are likely to change within the fixed term. Selling the property, paying down a lump sum from an inheritance or sale of another asset, or consolidating debt from a business or investment often trigger break costs that erase the benefit of the fixed rate.
In a scenario where a borrower refinances to a three-year fixed rate to reduce repayments, then receives a work relocation or financial windfall 18 months later, the break cost can exceed the interest saved during that period. The decision to fix should include a realistic assessment of how long you intend to hold the loan without major changes to the balance or security.
Split loans allow you to fix a portion of the balance and keep the rest variable. That structure gives you rate certainty on part of the debt while preserving flexibility to make extra repayments or access an offset account on the variable portion. A common split is 50/50, though the ratio should reflect your repayment behaviour and risk tolerance. Buyers who value the ability to pay down debt faster or who may need to access equity in the medium term should keep a larger portion variable. Those prioritising predictable repayments and protection from rate rises can weight the split toward fixed. You can read more about managing your loan structure in our guide to refinancing.
A fixed rate home loan provides certainty over repayments for a set period, but it introduces break costs, restricts additional repayments, and often removes offset functionality. The decision to fix, and for how long, depends on your financial position, your likelihood of needing flexibility, and the rate environment at the time you lock in. Comparing break cost formulas, portability terms, and comparison rates before signing will help you avoid the common mistakes that turn a fixed rate into a liability.

Frequently Asked Questions
What is a break cost on a fixed rate home loan?
A break cost is a fee charged by the lender if you exit a fixed rate loan before the term ends. It is calculated using the difference between your fixed rate and the lender's current cost of funds for the remaining period. The fee can be significant in a falling rate environment.
Can I transfer my fixed rate loan to a new property?
Some lenders offer portability, which allows you to transfer your fixed rate to a new property if you sell and buy during the fixed term. Not all lenders provide this feature, and conditions around timing and loan amount apply. If your loan is not portable, you will pay break costs when you sell.
What is the difference between the interest rate and the comparison rate?
The comparison rate includes the interest rate plus ongoing fees and a portion of upfront costs, calculated over a standard loan term. It provides a more accurate picture of total loan cost than the advertised rate alone. Fixed products often carry higher fees, which can increase the comparison rate.
Should I fix my entire home loan or split it between fixed and variable?
A split loan allows you to fix part of your balance for rate certainty while keeping the rest variable for flexibility. This structure suits borrowers who want predictable repayments but also value the ability to make extra repayments or use an offset account. The right split depends on your repayment behaviour and financial goals.
