A fixed rate home loan locks your interest rate for a set period, typically one to five years. Your repayments do not change during this period regardless of RBA decisions and you know exactly what your mortgage costs each month.

Fixed Rate vs Variable Rate: The Core Difference

A variable rate home loan moves with the market. When the RBA raises rates, your repayments increase. When rates fall, they decrease. Variable loans offer flexibility and access to features, including 100% offset accounts and unlimited extra repayments, that most fixed rate products do not provide. 

The Case for Fixing After the May 2026 Hike

The Cash Rate Is Now at the Previous Cycle Peak

With the cash rate at 4.35%, rates have returned to the level reached at the peak of the 2022 to 2023 hiking cycle. Borrowers who did not fix during that period absorbed every increase in full. Fixing now at today's rates provides complete protection if market pricing of a further increase to 4.70% proves correct.

Every additional 0.25% RBA rate hike adds approximately $80 to $95 per month in repayments on a $500,000 to $600,000 loan. If the cash rate reaches 4.70% as market pricing suggests, that is a further $80 to $95 per month that a fixed rate borrower avoids entirely.

Budget Certainty Has Become Critical

Three hikes in 2026 have already stretched household budgets significantly. For households managing school fees, childcare, rising grocery and energy costs and elevated loan repayments simultaneously, knowing exactly what your mortgage costs each month for the next one to two years provides essential financial breathing room.

Competitive Fixed Rates Remain Available Now

Some one and two year fixed rates are currently priced competitively relative to leading variable rates, as lenders price in expectations of the rate cycle peaking and eventually reversing. This window may narrow if the RBA delivers another hike and lenders reprice fixed terms upward in anticipation. 

When Fixing Is Still the Wrong Decision

You Plan to Sell or Refinance During the Fixed Term

Exiting a fixed rate loan before the term ends triggers break costs, calculated on the interest rate differential between your fixed rate and the current market rate for the remaining term.

If rates eventually fall from the current 4.35% peak during your fixed term, exiting early could cost tens of thousands of dollars. If you have any meaningful likelihood of selling your property or needing to refinance within the next one to three years, a fixed rate could be very expensive. Think carefully about your plans before committing.

You Plan to Make Significant Extra Repayments

Fixed rate loans typically cap additional repayments at around $10,000 per year before penalty charges apply. At the current 4.35% cash rate, making extra repayments to reduce your principal is one of the most financially valuable things you can do. A fixed rate prevents you from doing this efficiently, which is a meaningful trade-off at current rates.

You Want a Full 100% Offset Account

Most fixed rate home loans do not offer a 100% offset account. With variable rates now broadly in the 6.5% to 7% range following the May 2026 hike, every dollar in your offset is saving more in interest than at any point since 2012. Fixing means giving up access to this feature at the very moment it is most financially valuable. 

What Are Break Costs and Why Do They Matter?

Break costs arise when you exit a fixed rate loan before the end of the fixed period, whether by selling, refinancing or making a large lump-sum repayment. They are calculated on the lender's actual economic loss from the difference between your fixed rate and the current market rate for the remaining term.

In the current environment, where rates may have peaked, it is worth understanding both directions. If you fix now and rates subsequently fall from 4.35%, exiting your fixed rate early to access lower variable rates would trigger break costs. Always request a break cost estimate before committing to any fixed rate and always get the exact figure in writing before breaking an existing fixed rate loan. These figures change daily as wholesale rates move. 

The Split Loan: The Most Practical Strategy in May 2026

With genuine uncertainty about whether rates have peaked at 4.35% or will rise further to 4.70%, a split loan balances protection against further hikes with flexibility to benefit if rates eventually fall.

• Fix a portion, typically 50 to 60% of your total loan, protecting those repayments from any further rate hikes and providing budget certainty on that component

• Keep the remainder variable, maintaining access to the 100% offset account, unlimited extra repayments and the flexibility to benefit automatically if the RBA eventually cuts rates

• This structure means you are partially protected if rates go higher and partially positioned to benefit if they eventually come down, without committing entirely to either outcome

Following the May 2026 hike, the split loan has become the most commonly recommended structure from advisers for borrowers who have not yet acted. It hedges the genuine uncertainty about whether 4.35% is the peak or whether further hikes are ahead. 

How Long Should You Fix For After the May 2026 Hike?

• 1 to 2 year fixed: most competitive rates in the current market and the shortest commitment. If rates do peak at or near 4.35% and eventually fall, a shorter term means you access lower rates again sooner. This is the term most advisers are recommending in the current environment.

• 3 year fixed: slightly higher rate but provides certainty across a full potential rate cycle. A reasonable choice for borrowers who want predictability without committing for longer.

• 4 to 5 year fixed: carries the highest rate premium and the greatest break cost exposure if rates fall. Appropriate only if maximum long-term certainty is your primary concern and you are confident rates will not fall significantly during the fixed period.

Given the CBA forecast of a rate pause and the possibility of cuts in 2027, most advisers are recommending one to two year fixed terms. These provide near-term protection while keeping you positioned to benefit from any future reductions without a long-term lock-in. 

Should You Change Lenders When Fixing?

Your existing lender's fixed rate quote is almost never the most competitive in the market. Banks compete intensely on fixed rate pricing and it is common for non-bank lenders, regional banks and credit unions to offer meaningfully sharper fixed rates than the majors.

If you are considering fixing, compare the full market before committing. Combining a lender switch with fixing can secure both a more competitive rate and improved loan terms simultaneously.
