What Are Break Costs? (And Why Do Lenders Charge Them?)

Break costs are fees charged when you repay, refinance or change a fixed-rate home loan before the fixed term ends. 

Why do they exist? 

When you fix your rate, the bank locks in funding from wholesale markets based on your agreed repayment schedule. If you end that contract early, the bank may still be locked into those funding costs. 

Think of it like breaking a lease – you’re ending a contract early, so there may be a financial penalty. 

Break costs can apply when you: 

  • Sell your property 
  • Refinance to a better rate 
  • Switch from fixed to variable 
  • Make extra repayments above your allowed limit 
  • Pay out the loan entirely 

If you’re considering refinancing your home loan, it’s important to factor break costs into the decision.

How to Calculate Break Costs (The Formula Explained)

A simplified formula looks like this: 

Break cost = Loan amount × Remaining fixed term (years) × Interest rate difference 

Let’s break that down using a typical Sydney example. 

  • Loan amount: Your current balance (e.g. $650,000)
  • Remaining term: Time left on your fixed rate (e.g. 2 years remaining on a 3-year fixed)
  • Rate difference: The gap between your fixed rate and current wholesale rates (e.g. 1.8% = 0.018) 

Worked Example 

Loan: $650,000

Remaining fixed term: 2 years 

Rate difference: 1.8% (0.018) 

Calculation: $650,000 × 2 × 0.018 = $23,400 

Estimated break cost: $23,400 

Important: This is a simplified formula. Each lender uses slightly different calculations, often including present value adjustments and their own funding costs. You can read more about how wholesale interest rates affect break costs via the Australian Financial Complaints Authority guide.

Why Your Actual Break Cost Might Differ

Your real quote may vary because: 

  • Each lender calculates break costs differently
  • Wholesale rates (such as BBSW) change daily 
  • Some lenders apply present value adjustments 
  • Quotes are typically valid for 5 business days only

Always request an official break cost quote from your lender before making decisions.

Break Cost Calculator Examples (Real Sydney Scenarios)

Example 1: North Shore Homeowner Refinancing

Scenario:
  • $850,000 loan
  • 3 years remaining
  • Rate difference 2.0%

Calculation: $850,000 × 3 × 0.02 = $51,000

If refinancing saves 1.5% p.a.: $850,000 × 0.015 = $12,750 per year

Over 3 years = $38,250

Verdict: Break cost ($51,000) exceeds savings ($38,250). Better to wait.

 

Example 2: Western Sydney First-Time Buyer Upsizing

Scenario:
  • $500,000 loan
  • 1 year remaining
  • Rate difference 1.2%

Break cost: $500,000 × 1 × 0.012 = $6,000

Additional costs: $350 discharge fee + $800 application fee

Total ≈ $7,150

Verdict: A relatively small cost if you need to move for a growing family.

 

Example 3: Eastern Suburbs Investor Converting to Variable

Scenario:
  • $1,200,000 loan
  • 4 years remaining
  • Rate difference 0.8%

Break cost: $1,200,000 × 4 × 0.008 = $38,400

However, if wholesale rates have risen since fixing, break costs could be minimal or even $0.

Verdict: Always request an official quote – it may be far lower than expected.

 

Example 4: When Break Costs Are $0

If wholesale rates are now higher than when you fixed, the bank can actually profit when you break early.

In some cases, break costs are $0.

If you believe a lender has calculated your fees unfairly, the Australian Financial Complaints Authority (AFCA) can review disputes.

 

How Different Lenders Calculate Break Costs

Each lender has different policies on break costs, extra repayments, and what they call these fees.

Below is a comparison of major Australian lenders and how they generally structure their fixed-rate break policies.

Lender Break Cost Name Max Extra Repayments Prepayment Threshold
CBA Early Repayment Adjustment (ERA) $10,000 per year $10,000/year
Westpac Break Costs Up to 20% increase in repayments OR $30,000 total $30,000 total fixed period
NAB Prepayment Fees & Economic Cost $20,000 total fixed period $20,000 total
ANZ Early Repayment Fee (ERF) Lower of $5,000/year or 5% of loan Varies
St George Break Costs $30,000 total fixed period $30,000 total
Bankwest Break Costs $10,000 per year $10,000/year
Suncorp Early Payment Interest Adjustment (EPIA) $500 per month extra Varies
RAMS Fixed Rate Unwind Adjustment Varies by product Varies

Current as of February 2026. Policies may change – always check with your lender or speak with an AFMS broker.

 

Should You Break Your Fixed-Rate Loan? (Decision Framework)

Breaking a fixed-rate loan is not inherently good or bad – it simply needs to make financial sense in your circumstances. Below is a practical framework to guide your decision.

Step 1: Get Your Official Break Cost Quote

Start by requesting a formal break cost quote from your lender (or have your broker arrange it).

You will typically need:

  • Your loan account number
  • Current outstanding balance
  • Proposed break date

Most lenders provide quotes within 1–2 business days. Importantly, quotes are generally valid for five business days only, as wholesale funding rates change daily.

Step 2: Calculate Your Total Refinancing Costs

Break costs are only one component of the overall cost to refinance. You should also factor in:

  • Break cost (from the lender quote)
  • Discharge fee ($350–$500)
  • New loan application fee ($0–$800, depending on lender)
  • Valuation fee ($0–$300, often waived)
  • Legal or settlement fees
  • LMI (if your equity position has changed)

For example: Break cost ($12,000) + Discharge fee ($350) + Application fee ($600) = $12,950 total cost to refinance.

Assess the full cost of exiting, not just the break fee itself.

Step 3: Calculate Your Potential Savings

Next, calculate the savings from refinancing.

(Current rate − New rate) × Loan balance = Annual savings

Example: (5.5% − 4.2%) × $600,000 = 1.3% × $600,000 = $7,800 per year

If you have two years remaining on your fixed term: $7,800 × 2 = $15,600 total savings

If total break and refinance costs are $12,000, this produces a net benefit of $3,600.

It is also important to consider that savings begin immediately. If you remain on a lower rate beyond the original fixed period, long-term savings may substantially outweigh the upfront cost.

Step 4: Consider Non-Financial Factors

Financial calculations are essential, but personal circumstances also matter.

Breaking your fixed loan may be justified if you are:

  • Relocating for employment
  • Downsizing following separation
  • Upsizing for family needs
  • Experiencing financial or health hardship
 

Variable loans also provide flexibility, including:

  • Unlimited additional repayments
  • Offset account access
  • No break costs if you sell

For some borrowers, flexibility itself carries significant value.

 

Decision Matrix: Break or Wait?

Consider Breaking If:

  • Projected savings exceed total costs by at least 20%
  • You must sell for unavoidable reasons
  • You are moving from a relatively high fixed rate to a materially lower rate
  • Break costs are minimal or zero due to rising rates
 

Consider Waiting If:

  • Break costs exceed projected savings
  • Less than 12 months remain on your fixed term
  • You do not urgently need to refinance
  • The rate environment is uncertain
 

Seek Professional Advice If:

  • The financial outcome is marginal
  • You have multiple loans or a complex structure
  • You are considering loan portability or restructuring

If the numbers are close, it is recommended to get expert advice before proceeding.

 

How to Request a Break Cost Quote (Step-by-Step)

Option 1: Request Through Your Lender Directly

Call your lender’s home loan servicing team and request: “An official break cost quote for my fixed-rate loan.”

Ways to Avoid or Reduce Break Costs

While break costs cannot always be avoided, there are strategies that may reduce their impact.

Strategy 1: Use Loan Portability

If you are selling and buying simultaneously, some lenders allow you to transfer your existing fixed loan to the new property.

This can allow you to retain your fixed rate without incurring break costs.

Eligibility depends on:

  • Remaining with the same lender
  • Meeting valuation requirements
  • Completing settlement timelines correctly

Not all lenders offer this option.

Strategy 2: Wait for Rate Increases

Break costs are heavily influenced by wholesale funding rates.

If rates rise, your break cost may reduce – or potentially fall to zero.

You can monitor official cash rate decisions from the Reserve Bank of Australia and request updated quotes following rate increases.

Strategy 3: Use Your Extra Repayment Allowance

Most lenders permit $10,000–$30,000 in additional repayments during the fixed term without penalty.

For example: $650,000 loan − $30,000 extra repayment = $620,000 balance

Since break costs are calculated on the remaining balance, reducing the principal can lower the fee.

Strategy 4: Split Your Loan

If fixing again in the future, consider splitting your loan between fixed and variable portions.

For example: 50% fixed for certainty + 50% variable for flexibility

This structure may reduce exposure to full-loan break costs if circumstances change later.

Strategy 5: Negotiate with Your Lender

In some cases, lenders may reduce fees or offer retention incentives – particularly for long-term customers or where a competitive refinance offer exists.

A simple approach may be: “I’ve received a competitive offer elsewhere – can you match the rate or reduce my break costs?”

Our brokers negotiate these scenarios regularly and often achieve stronger outcomes due to established lender relationships.

 

Break Costs vs Other Refinancing Costs (The Complete Picture)

Break costs are only part of the overall financial picture.

Total Cost Breakdown Example

Loan: $750,000 – 2 years remaining on fixed term

  • Break cost: $18,000
  • Discharge: $350
  • Application: $600
  • Legal/settlement: $800

Total cost: $19,750

Compare to Total Savings Over Life of Loan

Refinancing from 5.5% to 4.5%:

1% × $750,000 = $7,500 saved annually

Over 2 years = $15,000

This creates a short-term gap of $4,750.

However, if you remain on the lower rate for five years or longer, cumulative savings can significantly exceed the upfront cost.

The key is to assess the longer-term benefit – not just the remaining fixed period.

EXPERT FINANCIAL SERVICES

Ways to Avoid or Reduce Break Costs

While break costs cannot always be avoided, there are strategies that may reduce their impact.

Use Loan Portability

If you're selling and buying at the same time, some lenders let you transfer your fixed loan to the new property – avoiding break costs entirely. You'll need to stay with the same lender and meet their valuation and settlement requirements.

Wait for Rate Increases

Break costs are tied to wholesale funding rates. If rates rise, your break cost may drop significantly – or fall to zero. Monitor RBA cash rate decisions and request updated quotes after any increase.

Use Your Extra Repayment Allowance

Most lenders allow $10,000–$30,000 in extra repayments during the fixed term without penalty. Since break costs are calculated on the remaining balance, paying down principal now can reduce your fee later.

Split Your Loan

Next time you fix, consider splitting between fixed and variable – for example, 50/50. This gives you rate certainty on one portion and flexibility on the other, reducing your exposure to full-loan break costs.

Negotiate with Your Lender

Lenders may reduce fees or offer retention deals, especially if you have a competitive refinance offer in hand. Our brokers handle these negotiations regularly and often secure better outcomes through established lender relationships.

Frequently Asked Questions About Break Costs

Break costs can range from $0 to $50,000 or more. 

For typical Sydney loans between $600,000 and $900,000, they often fall between $10,000 and $25,000, depending on balance, remaining term, and interest rate movements.

Yes, if: 

  • Your fixed term has ended 
  • Rates have risen materially since fixing 
  • You use loan portability 

Otherwise, break costs will generally apply unless projected savings outweigh them.

Typically five business days. 

Because wholesale funding rates move daily, quotes expire quickly and must be refreshed if not acted upon within that period.

Yes, for fixed-rate loans during the fixed period. 

Variable rate loans do not incur break costs (beyond standard discharge fees).

No. Moving from fixed to variable with the same lender still triggers break costs. 

Occasionally lenders may offer concessions, but this is not common. If you would like assistance negotiating, AFMS can help.

Many lenders allow break costs to be capitalised into the new loan balance. 

For example: $15,000 added to a $650,000 loan = $665,000 total balance 

This avoids upfront payment but increases the amount on which interest is charged.

If selling, the cost is typically deducted from settlement proceeds.

If experiencing financial hardship, contact your lender to discuss available assistance.

For investment properties, break costs may be deductible where the refinance relates to income-producing purposes. Make sure to keep all break cost documentation for tax records

For owner-occupied properties, they are generally not deductible. 

You should consult a qualified tax professional for advice specific to your circumstances. General guidance is available via the Australian Securities and Investments Commission MoneySmart website.
