Introduction

“Should I fix my home loan?” It’s the question Johnny Dastidar from Iconic Mortgage Solutions hears most often from Canberra homeowners. With interest rates fluctuating and economic uncertainty ongoing, the fixed versus variable decision feels more critical than ever.

But here’s what most Canberra borrowers don’t realise: it’s not an either/or decision. The most sophisticated homeowners use split loan strategies that combine fixed and variable components, creating structures that protect against rate rises while maintaining flexibility.

Whether you’re buying in Braddon, refinancing in Kingston, or building a property portfolio across Canberra, understanding fixed and variable strategies is essential for optimal wealth building.

Here’s everything you need to know to make the right decision for your situation.

Understanding Fixed Rate Home Loans

Fixed rate loans lock your interest rate for a specified period, typically 1-5 years.

How Fixed Rates Work

The lock-in:

• Interest rate guaranteed for fixed period
• Monthly payments remain constant
• Protected from rate increases
• Can’t benefit from rate decreases

Common fixed periods:

• 1 year: Short-term certainty
• 2 years: Moderate certainty
• 3 years: Most popular choice
• 5 years: Long-term protection

Example:

• Loan amount: $700,000
• Fixed rate: 5.89% for 3 years
• Monthly payment: $4,151
• Payment guaranteed for 36 months

Fixed Rate Advantages

Budget certainty: Know exactly what you’ll pay
Rate rise protection: Locked in regardless of market increases
Payment predictability: Easier financial planning
Peace of mind: No rate shock anxiety

Who benefits most:

• First home buyers establishing budgets
• Single-income families with tight cash flow
• Those planning major expenses
• Risk-averse personalities
• People expecting rate rises

Fixed Rate Disadvantages

No benefit from rate falls: Locked in even if rates drop
Limited flexibility: Restrictions on extra payments
Break costs: Penalties for early exit can be substantial
Fewer features: Often no offset account capability
Refinancing restrictions: Can’t easily change lenders

Case Study: The Martinez Family, Deakin

Carlos and Sophie fixed their $850,000 loan at 5.49% for 3 years in early 2023. When variable rates dropped to 5.29% in 2024, they couldn’t benefit.

Their cost:

• Rate difference: 0.20%
• Annual additional cost: $1,700
• 2-year cost: $3,400

“We accepted that trade-off for the certainty,” Carlos explains. “We knew rates could also go up, and the predictability was worth the premium to us.”

Understanding Variable Rate Home Loans

Variable rate loans fluctuate with market conditions, typically following RBA cash rate movements.

How Variable Rates Work

The flexibility:

• Interest rate changes with market
• Usually follows RBA rate decisions
• Can go up or down
• More features and flexibility

Rate movement patterns:

• Typically moves 0.25% increments
• Changes announced by lender
• Usually within days of RBA decisions
• Not guaranteed to match RBA exactly

Variable Rate Advantages

Rate decrease benefits: Payments reduce when rates fall
Maximum flexibility: Extra payments without restriction
Offset accounts: Usually available for interest reduction
No break costs: Can refinance or switch anytime
Feature-rich: Redraw, splits, and other options

Who benefits most:

• High-income earners making extra payments
• Investors using offset accounts strategically
• Those expecting rate decreases
• People valuing flexibility over certainty
• Borrowers likely to refinance

Variable Rate Disadvantages

Rate rise exposure: Payments increase with market rates
Budget uncertainty: Harder to plan long-term
Potential payment shock: Rapid increases possible
Discipline required: Extra payment features need self-control

Case Study: Dr. Sarah Chen, Specialist, Griffith

Sarah maintains her $1,100,000 loan on variable with substantial offset:

Structure:

• Loan: $1,100,000 at 6.09% variable
• Offset balance: $280,000
• Effective loan: $820,000
• Effective rate: 4.53%

“The offset benefit far outweighs the rate uncertainty,” Sarah explains. “My variable rate is effectively 1.56% lower than the headline rate because of my offset strategy.”

The Split Loan Strategy: Best of Both Worlds

Most sophisticated Canberra homeowners don’t choose fixed or variable—they choose both.

How Split Loans Work

Divide your total borrowing across multiple splits with different rate structures:

Typical split:

• Split 1: 50% fixed (certainty)
• Split 2: 50% variable (flexibility)

Alternative configurations:

• 70% fixed / 30% variable (more certainty)
• 30% fixed / 70% variable (more flexibility)
• Three-way split: fixed / fixed / variable

Split Loan Advantages

Balanced risk: Protected from some rate rises, benefit from some falls
Partial offset: Variable split can have offset account
Flexibility preserved: Can make extra payments to variable split
Staggered fixing: Different fixed periods create refinancing options
Customizable: Adjust split ratios to risk tolerance

Case Study: The Wilson Family Portfolio, Kingston

Mark and Lisa Wilson have $1,450,000 across their owner-occupied home and investment property:

Owner-occupied ($950,000):

• Split A: $475,000 fixed 3 years at 5.69%
• Split B: $475,000 variable at 6.09% with $180,000 offset

Investment ($500,000):

• Split C: $500,000 variable at 6.19% with $60,000 offset

Benefits:

• 50% protected from rate rises
• Offset accounts on variable splits saving ~$14,400 annually
• Flexibility for extra payments
• Staggered refinancing opportunities

“The split strategy gave us certainty where we needed it and flexibility where it matters most,” Mark explains.

Optimal Split Ratios

Conservative (70% fixed / 30% variable):

• Maximum certainty
• Minimal rate rise impact
• Limited offset benefit
• Best for: tight budgets, rate rise expectations

Balanced (50% fixed / 50% variable):

• Equal protection and flexibility
• Moderate offset benefit
• Reasonable extra payment capacity
• Best for: most Canberra families

Aggressive (30% fixed / 70% variable):

• Maximum flexibility
• High offset benefit potential
• Significant rate rise exposure
• Best for: high earners, rate fall expectations

Strategic Timing: When to Fix

Timing fixed rate decisions requires understanding rate cycles and personal circumstances.

Rate Cycle Considerations

When rates are low and expected to rise:

• Fix higher percentage (60-80%)
• Consider longer terms (3-5 years)
• Lock in low rates before increases

When rates are high and expected to fall:

• Fix lower percentage (20-40%)
• Consider shorter terms (1-2 years)
• Maintain flexibility for future decreases

When rates are uncertain:

• Balanced split (40-60%)
• Staggered terms for flexibility
• Regular review and adjustment

Personal Circumstance Factors

Cash flow tightness:

• Tighter budget = more fixed
• Comfortable cash flow = more variable

Income stability:

• Stable income = can handle variable
• Variable income = prefer fixed certainty

Savings capacity:

• High savings = benefit from offset on variable
• Minimal savings = fixed certainty valuable

Risk tolerance:

• Risk-averse = more fixed
• Risk-comfortable = more variable

Case Study: The Chen Family Decision, Yarralumla

In early 2024, the Chens faced a fixing decision on their $1,200,000 loan:

Market analysis:

• Variable rate: 6.24%
• 3-year fixed rate: 5.79%
• Economist predictions: rates to fall in 2025

Their decision:

• Fixed 40% ($480,000) at 5.79% for 2 years
• Variable 60% ($720,000) at 6.24% with offset

Rationale:

• Protected 40% from potential continued rises
• Positioned 60% to benefit from predicted falls
• Short 2-year term for reassessment flexibility
• Offset on variable split for immediate benefit

The Mathematics of Fixed vs Variable

Understanding the financial implications requires careful analysis.

Scenario Analysis: $800,000 Loan

Scenario 1: Rates rise 0.75% over 3 years

100% Variable:

• Starting rate: 6.10%
• Ending rate: 6.85%
• Total interest (3 years): $149,700

100% Fixed (5.89% for 3 years):

• Fixed rate: 5.89%
• Total interest (3 years): $142,100
• Saving: $7,600

50/50 Split:

• Total interest (3 years): $145,900
• Saving vs variable: $3,800

Scenario 2: Rates fall 0.50% over 3 years

100% Variable:

• Starting rate: 6.10%
• Ending rate: 5.60%
• Total interest (3 years): $141,300

100% Fixed (5.89%):

• Total interest (3 years): $142,100
• Cost: $800 more

50/50 Split:

• Total interest (3 years): $141,700
• Cost vs variable: $400

Analysis: Split strategies provide insurance against wrong predictions while limiting downside.

Break Costs: The Fixed Rate Exit Penalty

Understanding break costs is critical before fixing.

How Break Costs Are Calculated

When you exit a fixed loan early, the lender calculates their loss:

Formula (simplified): Break cost = (Fixed rate – Current fixed rate) × Remaining loan × Remaining term

Example:

• Loan: $600,000 fixed at 6.00%
• Time remaining: 2 years
• Current 2-year fixed rate: 5.50%
• Estimated break cost: ~$6,000

Why this happens: The lender locked in money at 6.00% to fund your loan. If they can only lend it at 5.50% now, they’ve lost 0.50% for 2 years.

When Break Costs Apply

Triggering events:

• Refinancing to another lender
• Selling the property
• Making extra payments above allowance
• Switching to variable early
• Splitting or restructuring loan

When break costs don’t apply:

• At end of fixed period
• Permitted extra payments (usually $10-30k annually)
• Rate switches within same lender (sometimes)

Case Study: Expensive Break Cost

David wanted to sell his Belconnen property with $520,000 remaining on a 5.19% fixed rate with 3 years remaining. Current fixed rates: 4.69%.

Break cost calculation:

• Rate differential: 0.50%
• Amount: $520,000
• Time: 3 years
• Break cost: ~$7,800

This unexpected cost significantly reduced David’s sale proceeds.

“I had no idea breaking my fixed loan would cost so much,” David admits. “Now I know to always ask about break costs before fixing.”

Fixed Rate Features and Restrictions

Fixed loans typically come with limitations that borrowers must understand.

Common Fixed Loan Restrictions

Extra payment limits:

• Usually $10,000-$30,000 per year
• Excess triggers break costs
• Some lenders allow none

Offset accounts:

• Rarely available on fixed splits
• If available, often limited benefit
• Variable splits needed for offset

Redraw facilities:

• Limited or unavailable
• Extra payments often locked away
• Less flexible than variable

Splitting:

• Fixed loan can’t usually be split further
• Restructuring may trigger break costs

Questions to Ask Before Fixing

• What extra payments are allowed annually?
• Is redraw available on fixed portion?
• What triggers break costs?
• Can I split this fixed loan later?
• What happens if I sell the property?
• Can I port the fixed loan to a new property?

Refinancing Considerations

Your fixed/variable decision impacts future refinancing options.

Refinancing from Fixed Loans

Challenges:

• Break costs can be substantial
• Must wait until fixed period ends
• Or pay penalty to switch early

Strategies:

• Time refinance to end of fixed period
• Negotiate with existing lender first
• Calculate if savings exceed break costs

Case Study: Strategic Refinancing

Emma had $750,000 fixed at 6.49% with 8 months remaining. Competitor offered 5.79% variable.

Analysis:

• Wait 8 months: Pay 6.49% for $50,000 interest
• Refinance now with $4,200 break cost: Save $3,100 over 8 months
• Net benefit from waiting: $1,100

Emma waited the 8 months, then refinanced without break costs.

Refinancing from Variable Loans

Advantages:

• No break costs
• Can switch anytime
• Flexibility to chase best rates

Strategy:

• Annual rate reviews
• Negotiate with existing lender
• Switch if savings justify costs
