According to major banks
With the RBA cash rate sitting at 3.85% and mortgage rates at their highest in over a decade, Australian homeowners face a critical decision: lock in a fixed rate for certainty, or stay variable and ride out the storm? This comprehensive guide breaks down everything you need to know to make the right choice for your situation.
Understanding Fixed vs Variable Rates
Fixed Rate Home Loans
A fixed rate loan locks in your interest rate for a set period (typically 1-5 years). Your repayments won't change during this time, regardless of RBA decisions or market movements.
Pros of Fixed Rates
- ✓ Budgeting certainty: Know exactly what you'll pay each month
- ✓ Protection from rate rises: If rates go up, you're protected
- ✓ Peace of mind: No stress about RBA announcements
- ✓ Currently competitive: Fixed rates often lower than variable
Cons of Fixed Rates
- ✗ Less flexibility: Limited extra repayments (usually $10,000/year)
- ✗ Break costs: Expensive to exit early (can be $10,000+)
- ✗ No offset account: Most fixed loans don't offer offset
- ✗ Miss rate cuts: Won't benefit if rates drop
Variable Rate Home Loans
Variable rates fluctuate with the market and RBA decisions. Your repayments can go up or down at any time.
Pros of Variable Rates
- ✓ Maximum flexibility: Make unlimited extra repayments
- ✓ Offset account: Reduce interest with your savings
- ✓ Redraw facility: Access extra repayments when needed
- ✓ Benefit from rate cuts: Instant savings when rates drop
Cons of Variable Rates
- ✗ Repayment uncertainty: Hard to budget long-term
- ✗ Rate rise risk: Payments increase with rate hikes
- ✗ Currently expensive: Variable rates higher than fixed
- ✗ Stress factor: Constant monitoring of rates
Current Market Analysis: August 2025
The Australian mortgage market is at a critical juncture. Here's what's happening:
Market Conditions
- Fixed rates are lower: 2-year fixed rates average 0.55% below variable
- Banks expect rate cuts: Most predict first cut in Q4 2025 or Q1 2026
- Inflation moderating: Down to 3.8% from peak of 7.8%
- Fixed rate popularity: 35% of new loans are fixed (up from 15% in 2022)
Who Should Choose Fixed?
Fixed rates might be right for you if:
- You're on a tight budget and need payment certainty
- You believe rates will stay high or rise further
- You won't need to sell or refinance during the fixed period
- You don't plan to make large extra repayments
- You value peace of mind over flexibility
Example: Fixed Rate Winner
Sarah has a $600,000 mortgage and fixes at 5.89% for 2 years. If variable rates rise to 7.5%, she'll save $7,260 per year compared to variable borrowers.
Who Should Choose Variable?
Variable rates might suit you if:
- You want maximum flexibility with your loan
- You have savings to put in an offset account
- You expect to receive bonuses or windfalls to pay down the loan
- You think rates will drop within 12-18 months
- You might need to sell or refinance soon
Example: Variable Rate Winner
Michael has $200,000 in his offset account against a $700,000 loan. The offset saves him $13,680/year in interest - a benefit he'd lose with most fixed loans.
The Split Loan Strategy
Can't decide? Consider splitting your loan - fix a portion for certainty while keeping some variable for flexibility.
Popular Split Strategies
- 50/50 split: Balance of certainty and flexibility
- 70/30 fixed/variable: More certainty, some flexibility
- 30/70 fixed/variable: Mostly flexible with some protection
Note: Splits may have higher fees and complexity
Rate Predictions: What the Experts Say
| Bank | First Rate Cut | Cash Rate End 2026 |
|---|---|---|
| Commonwealth Bank | February 2026 | 3.60% |
| Westpac | November 2025 | 3.35% |
| ANZ | February 2026 | 3.85% |
| NAB | May 2026 | 3.85% |
Making Your Decision: Key Questions
Ask yourself these questions:
- Can I afford a 2% rate increase? If no, consider fixing.
- Do I have significant savings? If yes, variable with offset might save more.
- Will I move in the next 2-3 years? If yes, avoid fixed to prevent break costs.
- Do I get bonuses or irregular income? If yes, variable allows extra repayments.
- Am I losing sleep over rates? If yes, fixed offers peace of mind.
The Bottom Line
In the current market, with fixed rates sitting below variable rates and uncertainty about when cuts will arrive, many borrowers are choosing to fix for 1-2 years. This provides payment certainty during a volatile period while avoiding locking in for too long.
However, if you value flexibility, have substantial savings for an offset account, or believe rates will drop sooner than expected, variable remains a valid choice. The key is choosing what aligns with your financial situation and risk tolerance.
Remember
There's no one-size-fits-all answer. The best choice depends on your personal circumstances, financial goals, and risk appetite. Consider speaking with a mortgage broker who can model different scenarios based on your specific situation.
