Break Costs (also called break fees or economic cost) are penalties charged when you exit a fixed-rate loan before the fixed period ends. These costs compensate the lender for lost interest income and can range from $500 to $30,000+ depending on the loan size, remaining fixed term, and interest rate movements.
How Break Costs Work
When you lock in a fixed rate, the lender funds your loan at that rate for the entire fixed period. If you exit early, they lose expected interest—break costs recover this loss.
Break costs apply when you:
- Refinance to another lender during fixed period
- Sell your property during fixed period
- Make extra repayments above allowed limits (typically $10K-$30K/year)
- Pay off loan entirely (inheritance, windfall)
Example:
- Loan: $650,000 fixed @ 5.5% for 5 years
- 2 years into fixed period, you want to refinance
- Remaining fixed term: 3 years
- Current market rate: 6.3% (rates rose)
- Break cost: $0 (lender can re-lend at higher rate)
Opposite scenario:
- Same loan: $650,000 fixed @ 5.5% for 5 years
- 2 years in, you want to refinance
- Remaining term: 3 years
- Current market rate: 4.8% (rates fell)
- Lender loses: 0.7% × $630,000 × 3 years = ~$13,230
- Break cost: $13,230 (lender's loss becomes your cost)
Break Cost Calculation
Interest Rate Differential Method (Most Common)
Formula: Break Cost = (Fixed Rate - Current Rate) × Remaining Loan Balance × Remaining Fixed Term (in years)
This is simplified—actual calculations use present value discounting.
Example 1: Rates fell (you pay)
- Loan balance: $580,000
- Fixed rate: 5.9%
- Current wholesale rate: 5.1%
- Differential: 0.8%
- Remaining term: 2.5 years
- Break cost: 0.8% × $580,000 × 2.5 = $11,600
Example 2: Rates rose (no cost)
- Loan balance: $520,000
- Fixed rate: 5.5%
- Current wholesale rate: 6.4%
- Differential: -0.9% (in your favor)
- Break cost: $0 (lender benefits from being able to re-lend higher)
Example 3: Same rates (minimal cost)
- Loan balance: $600,000
- Fixed rate: 5.8%
- Current wholesale rate: 5.75%
- Differential: 0.05%
- Remaining term: 1 year
- Break cost: 0.05% × $600,000 × 1 = $300 (admin cost)
Wholesale Rate vs Advertised Rate
Important: Lenders use wholesale/swap rates (not advertised rates) in calculations.
Example:
- Your fixed rate: 5.9%
- Current advertised fixed rate: 6.5%
- You think: "Rates rose, no break cost"
- Current wholesale rate: 5.2% (what lenders actually pay)
- Differential: 0.7% (you owe break cost)
- Break cost: $8,900 on $550,000 with 2 years remaining
You can't calculate exact break costs yourself—must ask lender.
Scenarios That Trigger Break Costs
1. Refinancing to Another Lender
Most common scenario.
Example:
- Fixed loan: $620,000 @ 5.8%, 2 years remaining
- Want to refinance to variable @ 6.1%
- Current wholesale rate: 5.0%
- Break cost: $9,920
- Refinancing costs: $1,800
- Total cost to exit: $11,720
Is it worth it?
- Fixed repayment: $3,628/month
- New variable repayment: $3,716/month
- Refinancing costs more (don't refinance)
Different scenario:
- Want to refinance to 5.3% variable
- New repayment: $3,440/month
- Savings: $188/month = $4,512 over 2 years
- Break cost + refinancing: -$11,720
- Net loss: $7,208 (wait until fixed period ends)
2. Selling Property
Can't avoid break costs if you sell.
Example:
- Sell home to upsize
- Fixed loan: $480,000 @ 5.7%, 18 months remaining
- Wholesale rate: 5.3%
- Break cost: $2,880
- Sale proceeds: $850,000
- Pay break cost from sale proceeds (unavoidable)
3. Paying Off Loan (Inheritance, Windfall)
Example:
- Inheritance: $550,000
- Fixed loan: $540,000 @ 5.9%, 3 years remaining
- Wholesale rate: 5.2%
- Break cost: $11,340
Options:
- Pay off loan, pay $11,340 break cost
- Keep loan, invest inheritance elsewhere
- Partial payoff: Pay allowed amount ($30K/year), invest rest
Cost-benefit:
- Save on loan interest: 5.9% on $540,000 = $31,860/year
- Invest inheritance: Assume 6% return = $33,000/year
- Better to invest and keep loan (especially after paying $11,340 break cost)
4. Exceeding Extra Repayment Limits
Most fixed loans allow $10K-$30K extra repayments per year.
Example:
- Fixed loan: $600,000
- Extra repayment limit: $20,000/year
- You pay: $50,000 extra
- Excess: $30,000
- Break cost on $30,000: ~$1,200 (2 years remaining)
- Charged $1,200 for paying down too much
Solution: Only pay up to the allowed limit per year.
When Break Costs Are High
1. Interest Rates Fell Significantly
Example:
- Fixed @ 6.2% in early 2023
- Rates fell to 5.1% by 2024
- Differential: 1.1%
- Loan: $700,000, 3 years remaining
- Break cost: ~$23,000
2. Long Remaining Fixed Period
Example:
- 5-year fixed loan, exit after 6 months
- Remaining: 4.5 years
- Rate differential: 0.6%
- Loan: $650,000
- Break cost: ~$17,550
3. Large Loan Balance
Example:
- Loan: $1,200,000
- Differential: 0.5%
- Remaining: 2 years
- Break cost: $12,000
When Break Costs Are Low or Zero
1. Interest Rates Rose
Most common scenario in 2022-2024 (rising rate environment).
Example:
- Fixed @ 5.3% in 2022
- Rates rose to 6.8% by 2024
- Wholesale rate: 6.5%
- Break cost: $0 (lender benefits from exiting your low rate)
2. Near End of Fixed Period
Example:
- Fixed loan: 3 years
- Remaining: 4 months
- Differential: 0.7%
- Loan: $580,000
- Break cost: 0.7% × $580,000 × 0.33 years = $1,339 (manageable)
3. Small Loan Balance
Example:
- Loan: $180,000 (paid down significantly)
- Differential: 0.8%
- Remaining: 2 years
- Break cost: $2,880 (lower because balance is low)
Avoiding or Minimizing Break Costs
1. Choose Shorter Fixed Periods
Strategy: Fix for 1-2 years instead of 3-5 years.
Comparison:
- 5-year fixed @ 5.8%: If rates fall, high break costs for years
- 2-year fixed @ 5.9%: Lower break cost risk (shorter exposure)
Example:
- Exit after 1 year
- 5-year fixed: 4 years remaining, break cost $15,000
- 2-year fixed: 1 year remaining, break cost $3,800
- Save $11,200 in break costs
2. Split Loan (Fixed + Variable)
Strategy: Only fix portion of loan, keep rest variable.
Example:
- Total loan: $650,000
- Split:
- $400,000 fixed @ 5.7% (stability)
- $250,000 variable @ 6.2% (flexibility)
If you sell/refinance:
- Break cost only on $400,000 portion
- Pay off $250,000 variable with no penalty
- Reduce break cost exposure
3. Port Your Loan (Keep Same Lender)
Some lenders allow "porting" to new property without break costs.
Example:
- Sell home with $500,000 fixed loan
- Buy new home for $850,000
- Keep existing $500,000 fixed loan
- Add $350,000 variable loan
- No break cost (continued with same lender)
Limitations:
- Must stay with same lender (can't shop for better rate)
- New property must be similar or higher value
- Subject to new servicing assessment
4. Time Exit to Minimize Costs
Strategy: Wait for rates to rise before refinancing fixed loan.
Example:
- Monitoring fixed loan since month 6
- Month 12: Rates rise significantly
- Break cost: $0
- Refinance immediately (no penalty)
5. Make Maximum Allowed Extra Repayments
Strategy: Pay down within allowed limits each year.
Example:
- Fixed loan: $600,000, limit $20K/year extra
- Year 1: Pay $20,000 extra
- Year 2: Pay $20,000 extra
- Year 3: Pay $20,000 extra
- Total paid down: $60,000 with $0 break costs
Break Costs vs Early Exit Fees
Break Costs (Fixed Loans)
- Compensate lender for lost interest income
- Variable amount ($0 to $30,000+)
- Based on interest rate movements
- Can't be avoided if rates fell
Early Exit Fees (Variable Loans)
- Flat fee set in loan contract
- Fixed amount (typically $300-$800)
- Not related to interest rates
- Applies within first 1-4 years
Example:
- Fixed loan break cost: $12,500 (rates fell)
- Variable loan early exit fee: $650 (fixed amount)
Variable loans are cheaper to exit.
Calculating Break Cost Before Exiting
Request Payout Figure
Process:
- Call lender or login to online banking
- Request "payout figure" or "discharge figure"
- Lender provides:
- Current loan balance
- Accrued interest
- Discharge fee ($350-$800)
- Break cost (if applicable)
- Total amount required to close loan
Example payout statement:
- Loan balance: $582,340
- Accrued interest (to settlement): $1,250
- Discharge fee: $395
- Break cost: $8,920
- Total payout: $592,905
Break Cost Estimates
Some lenders provide online calculators:
- Login to internet banking
- Enter proposed settlement date
- View estimated break cost
Always request official quote 7-10 days before planned exit.
Real-World Examples
Example 1: Break Cost Makes Refinancing Not Worth It
Scenario:
- Fixed loan: $620,000 @ 5.9%, 2 years remaining
- Want to refinance to 5.4% variable (save 0.5%)
- Break cost: $6,200
- Refinancing costs: $1,800
- Total cost: $8,000
Analysis:
- Interest savings: 0.5% × $620,000 = $3,100/year × 2 years = $6,200
- Cost to exit: $8,000
- Net loss: $1,800 (not worth it)
Decision: Wait 2 years for fixed period to end.
Example 2: Selling Property (Unavoidable Break Cost)
Scenario:
- Selling home to relocate for work
- Fixed loan: $540,000 @ 5.8%, 18 months remaining
- Wholesale rate: 5.3%
- Break cost: $4,050
- Must pay (no choice)
Strategy:
- Sale price: $850,000
- Pay off loan: $540,000 + $4,050 break cost
- Net proceeds: $305,950 (after agent fees, break cost)
Example 3: No Break Cost (Rates Rose)
Scenario:
- Fixed @ 5.4% in 2022 for 3 years
- 2024: Want to refinance (18 months remaining)
- Current wholesale rate: 6.2% (rates rose)
- Break cost: $0 (lender happy to exit low-rate loan)
- Refinancing costs: $1,500
- New rate: 6.1% variable
Analysis:
- Old repayment: $3,380/month (fixed 5.4%)
- New repayment: $3,650/month (variable 6.1%)
- Higher repayment, but you get offset account and flexibility
- Refinance completed with $0 break cost
Example 4: Inheritance Payoff Decision
Scenario:
- Inheritance: $600,000
- Fixed loan: $590,000 @ 6.1%, 3 years remaining
- Break cost: $10,600
- Current savings rate: 5.3% p.a.
Option A: Pay off loan
- Pay: $590,000 + $10,600 = $600,600
- Save interest: 6.1% on $590,000 = $36,000/year
- Cost: $10,600 break cost
Option B: Keep loan, invest inheritance
- Invest $600,000 @ 5.3% = $31,800/year
- Pay loan interest: $36,000/year
- Net cost: $4,200/year
Better to pay off loan (save $36,000/year interest vs earn $31,800, plus avoid $10,600 break cost).
Common Mistakes
1. Assuming No Break Costs Because Rates Rose
Mistake:
- Rates rose from 5% to 6.5%
- Assume: "Rates rose, no break cost"
- Reality: Wholesale rate only rose to 5.8%
- Your fixed: 6.1%
- Break cost: $4,500 (unexpected)
Solution: Always request official break cost estimate.
2. Not Factoring Break Costs into Refinancing Decision
Mistake:
- See better rate, apply to refinance
- Get formal approval
- Request break cost: $9,500
- Refinancing no longer worth it
- Wasted time and application fee
Solution: Request break cost estimate BEFORE applying to refinance.
3. Paying Too Much Extra
Mistake:
- Fixed loan allows $20K/year extra
- You pay $50,000 thinking it's smart
- Charged break cost on $30,000 excess: $1,800
- Penalty for paying off too fast
Solution: Know your extra repayment limits and stick to them.
4. Forgetting About Break Costs When Selling
Mistake:
- Accept offer on home
- 60-day settlement
- Request payout figure
- Break cost: $7,200 (unexpected)
- Now short on funds for new purchase deposit
Solution: Request break cost estimate when listing property (budget accordingly).
Fixed vs Variable: Break Cost Perspective
Fixed Loan Risks
Pros:
- Rate certainty
- Fixed repayments
Cons:
- Break costs if rates fall or you need to exit early
- Less flexibility (can't make unlimited extra repayments)
Variable Loan Benefits
Pros:
- No break costs (only small exit fee $300-$800 in first 1-4 years)
- Unlimited extra repayments
- Offset accounts (save interest)
Cons:
- Rate can rise (repayments increase)
- Less certainty
For flexibility: Variable loan is better (avoid break cost risk).
Final Thoughts
Break costs protect lenders from interest rate risk—when you exit a fixed loan early and rates have fallen, you'll pay the lender's lost interest income.
Key principles:
- Break costs range from $0 to $30,000+ (depends on rate movements, loan size, time remaining)
- Always request official break cost estimate before refinancing or selling
- If rates rose since you fixed, break cost is usually $0
- If rates fell, break costs can be significant ($5K-$20K)
- Consider shorter fixed periods (1-2 years) to minimize break cost exposure
- Split loans (fixed + variable) reduce break cost risk
When to accept break costs:
- Selling property (unavoidable)
- Refinancing saves significantly more than break cost
- Substantial life change (consolidating properties, moving overseas)
When to avoid:
- Break cost exceeds refinancing savings
- Near end of fixed period (wait 6-12 months)
- Rates likely to rise soon (wait for break cost to drop to $0)
Typical scenarios:
Low/no break cost:
- Rates rose: $0
- Near end of term: $1,000-$3,000
- Small loan: $500-$2,000
High break cost:
- Rates fell 1%+: $15,000-$30,000
- Large loan: $10,000-$25,000
- Long remaining term: $8,000-$20,000
Before exiting a fixed loan, request an official break cost estimate from your lender—this is free and takes 24-48 hours. Factor this into your refinancing decision.
Speak to a NIK Finance broker if you're considering exiting a fixed loan—they can request break cost estimates and help determine whether refinancing is financially beneficial after accounting for all costs.
Break costs are the price of flexibility—if you might need to exit your loan early, consider variable rates or shorter fixed periods to minimize this risk.
