Fixed vs Variable Rate in 2026: How to Make the Right Decision
- The RBA raised the cash rate to 4.10% in March 2026. Variable rates for most borrowers now sit between 6.1% and 6.7%. Further increases are forecast.
- Fixed rates are priced by lenders based on expected future rate movements — banks already factor in anticipated hikes when setting fixed rates.
- Fixing provides certainty and protection from further rises, but costs you flexibility: limited extra repayments, no offset account, and break costs if you need to exit.
- The right answer depends on your financial situation, risk tolerance, and plans — not on trying to 'win' against the market.
- A split loan — fixing part, keeping part variable — is the most common broker recommendation in rising rate environments and eliminates the need to pick a side.
- For investment properties, fixing requires careful consideration of IO period interaction, offset account loss, and depreciation deductibility structure.
Two RBA cash rate increases in 2026 — 0.25% in February and another 0.25% in March — have reignited the fixed vs variable debate for Australian borrowers. With the cash rate now at 4.10% and major banks forecasting another hike in May, the decision about how to structure your loan rate is as consequential as it has been at any point in the past decade.
The Current Rate Environment — What You Actually Need to Know
As at April 2026:
RBA cash rate: 4.10% (after hikes in February and March 2026)
Typical discounted variable rates for owner-occupiers (P&I, 80% LVR): approximately 6.0%–6.4%
Major bank standard variable rates: approximately 8.0%–8.1% (these are the 'loyalty tax' rates for existing customers who haven't negotiated)
2-year fixed rates: approximately 6.3%–6.7% (rising ahead of expected further hikes)
3-year fixed rates: approximately 6.4%–6.8%
5-year fixed rates: approximately 6.5%–6.9%
Market forecast: two to three major banks have forecast a further 0.25% hike in May 2026, potentially bringing the cash rate to 4.35%
An important nuance: fixed rates are already priced by lenders to reflect their expectations of where variable rates will go. If a 3-year fixed rate is 6.6% and your current variable rate is 6.2%, the bank is effectively telling you it expects variable rates to average at least 6.6% over the next three years. Fixing is not getting ahead of the bank — it is paying the bank's price for certainty.
What Fixing Your Rate Actually Does
A fixed rate loan locks in your interest rate for a set term — typically 1, 2, 3, or 5 years. During this period, your rate (and your repayments) don't change regardless of what the RBA does.
What fixing gives you:
Certainty. Your repayment amount is fixed for the entire term. You can budget precisely.
Protection from rate rises. If the RBA hikes rates further during your fixed term, you don't pay more.
What fixing costs you:
Extra repayment limits. Most fixed loans restrict additional repayments to $10,000–$20,000 per year.
No offset account. The majority of Australian lenders do not offer a full offset account on fixed rate loans.
Break costs if you exit early. If you need to sell, refinance, or pay out the loan before the fixed term ends, break costs apply.
Missed benefit if rates fall. If the RBA reverses course and cuts rates, you're locked in at the higher rate.
What Staying Variable Means
A variable rate loan moves with market conditions — typically in line with RBA cash rate decisions, though lenders can also move rates independently.
What variable gives you:
Flexibility. Make unlimited extra repayments. Access an offset account. Refinance without break costs.
Benefit from rate cuts. If rates fall, your repayment drops automatically.
Lender negotiation power. With a variable loan, you can approach your lender at any time to negotiate a better rate.
What variable costs you:
Rate rise exposure. If the RBA continues hiking, your repayments increase.
Budget uncertainty. You cannot precisely predict your repayment 12 months from now.
The Decision Framework
| Question | If YES, lean toward... | If NO, lean toward... |
|---|---|---|
| Can you absorb a further 0.5%–1.0% rate rise without financial stress? | Variable (you can handle the uncertainty) | Fixed (remove the uncertainty) |
| Do you hold significant savings you want to offset? | Variable (keep the offset account) | Fixed may be viable if savings are minimal |
| Are you planning to sell or refinance within 2–3 years? | Variable (avoid break costs) | Fixed only if selling timeline is certain and exceeds fixed term |
| Is your income unpredictable or project-based? | Fixed (certainty helps budgeting) | Variable (extra repayment flexibility) |
| Do you want to make aggressive extra repayments? | Variable (no repayment limits) | Fixed locks in a cap on extra payments |
The Split Loan Strategy — Why Most Brokers Recommend It
A split loan divides your mortgage into two portions: one on a fixed rate and one on a variable rate. This is not a compromise — it is a deliberate strategy that gives you the benefits of both structures.
Split Loan in Practice Example: $700,000 loan. Split 60% fixed ($420,000 at 6.5% for 3 years) and 40% variable ($280,000 at 6.2%). Your fixed portion gives you certainty on the majority of your debt. Your variable portion keeps an offset account available for your savings, allows unlimited extra repayments, and gives you refinancing flexibility. If rates rise 0.5%, your variable repayment increases by approximately $117/month — manageable, not catastrophic. If rates fall, your variable portion benefits immediately.
Common split ratios in the current environment (April 2026):
50/50 split: Equal portions fixed and variable. Maximum balance between certainty and flexibility.
70/30 fixed/variable: Higher certainty bias, suitable for borrowers most concerned about further rate rises.
30/70 fixed/variable: Higher flexibility bias, suitable for borrowers with large savings to offset.
Special Considerations for Investors
Investment property loans have unique considerations that change the fixed vs variable calculation:
Offset accounts and tax deductibility: Fixed loans typically don't offer offset accounts. For investors, losing the offset account means losing a tax-efficient savings vehicle.
Interest-only periods: IO periods and fixed rate terms are set independently. If your IO period expires during a fixed term, your repayments change significantly. Coordinate these carefully with your broker.
Portfolio management: If you have multiple investment properties, fixing across the entire portfolio can create a 'cliff effect' where all fixed terms expire simultaneously. Stagger fixed terms by property or loan split to smooth this.
Break Costs — The Most Important Number Nobody Calculates
If there is one thing to commit to memory about fixed rate loans, it is this: always know your break cost before making any decision about your fixed loan.
Break costs are calculated based on the movement in wholesale interest rates (bank bill swap rates) between when you fixed and when you break. The formula varies by lender but broadly:
Break Cost = Outstanding Loan Balance × (Fixed Rate − Current Wholesale Rate) × Remaining Fixed Term
Borrowers who fix now and then rates fall in 2027-2028 may face significant exit costs. Always get a written quote from your lender before making any decision.
Frequently Asked Questions
Can I fix part of my loan now and convert the rest later?
Yes. You can request a partial fix at any time on most variable loans. Contact your lender or broker to split your current variable loan into fixed and variable portions.
What happens when my fixed term ends?
At the end of a fixed term, your loan typically reverts to the lender's standard variable rate — which is often significantly higher than the discounted rate available to new customers. Start reviewing your options 3–6 months before your fixed term expires.
Is there a penalty for making extra repayments during a fixed term?
Most fixed loans allow $10,000–$20,000 in additional repayments per year without penalty. Exceeding this limit typically triggers a fee calculated similarly to an early exit break cost.
