“Fixing your home loan rate in 2026 involves paying a premium over the variable rate for the certainty it provides. The real decision is understanding if that premium is worth it for your situation.”
Switching to a fixed rate involves direct and indirect costs, such as rate premiums, variation fees, and potential break costs.
The rate premium
At mid-2026, one and two-year fixed rates from the major banks are running approximately 0.2–0.5% above equivalent variable rates. On a $600,000 loan, a 0.3% rate premium translates to approximately $1,800 per year in additional interest cost. That’s what you pay for the certainty of a fixed repayment.
Application and switching fees
Switching from variable to fixed with your existing lender typically incurs a loan variation fee of $150–$400. Some lenders waive this. Switching lenders at the same time adds discharge costs, new application fees, and potentially a valuation — totalling $500–$1,500 on a standard refinance.
Break cost risk
Once you’re on a fixed rate, the primary cost risk is the break cost if you exit before the term ends. Break costs are calculated based on the difference between your fixed rate and current wholesale funding rates, applied to your remaining balance and term. In a rising rate environment, break costs are often lower than in a falling one — but they should always be obtained in writing before any decision to exit.
The true cost comparison
The cost of fixing is the rate premium you pay over variable for the duration of the fixed term, plus any fees, minus the break cost savings if rates rise beyond your fixed rate. That calculation depends on what happens to rates — which is why the honest answer is that fixing has a cost, not a guaranteed saving.
