Early Repayment Charges on Fixed Rate Loans — Australia (2026)
Breaking a fixed rate home loan in Australia can be expensive — sometimes very expensive. If you sell, refinance or make extra repayments above the allowed threshold during a fixed rate period, your lender may charge a break cost (also called an “early repayment charge” or “economic cost”). On a $600,000 loan with several years remaining, break costs can exceed $20,000–$30,000.
What Is a Fixed Rate Break Cost?
A fixed rate break cost compensates the lender for the financial loss they incur when you repay a fixed rate loan before the end of the fixed term.
When your lender offers you a fixed rate, they fund that loan at a corresponding wholesale rate (usually the bank bill swap rate or a similar benchmark). If interest rates have fallen since you fixed, the lender can only re-deploy those funds at a lower rate — and you are charged for that difference.
The break cost is essentially: the lender’s “loss” from re-deploying money at a lower rate × the remaining term × the loan balance.
When Do Break Costs Apply?
| Trigger | Break Cost? |
|---|---|
| Selling your property during fixed period | Yes |
| Refinancing to a new lender during fixed period | Yes |
| Extra repayments above annual limit | Yes (on the excess) |
| Switching from fixed to variable mid-term | Yes |
| Fixed term expires naturally | No |
| Loan repaid on the day the fixed term ends | No |
Most lenders allow some extra repayments on fixed rate loans (typically $10,000–$30,000 per year) without a break cost. Repaying more than this limit triggers the break cost on the excess.
How Are Break Costs Calculated?
The formula is not standardised across lenders, but the general structure is:
Break cost ≈ (Fixed rate − Current wholesale rate for remaining term) × Loan balance × Remaining term (in years)
Simplified example:
- Remaining loan balance: $500,000
- Fixed rate you’re locked in at: 6.0% p.a.
- Current wholesale rate for 2-year term: 4.5% p.a.
- Remaining fixed term: 2 years
Break cost ≈ (6.0% − 4.5%) × $500,000 × 2 = 1.5% × $500,000 × 2 = $15,000
This is illustrative only — lenders use their own calculation methodology and may factor in funding costs differently.
When Are Break Costs Zero?
Break costs are zero or near-zero when:
- Interest rates have risen since you fixed — if current wholesale rates are above your fixed rate, the lender loses nothing by you repaying. In this scenario, your break cost is typically zero.
- Fixed term is almost complete — with only weeks remaining, the break cost is minimal
- You refinance at the exact end of the fixed term — always plan refinancing to coincide with the end of your fixed term to avoid break costs
Interest Rate Context — 2026
In 2026, the RBA cash rate is approximately 3.85%. Rates fell from their 2022–2023 highs (peak ~4.35%). Borrowers who fixed at high rates (6.0–7.0%+ in 2022–2024) may find current wholesale rates are below their fixed rate — meaning break costs could be significant if they try to refinance.
Conversely, borrowers who fixed at low rates in 2020–2021 (1.5–2.5%) and break in 2025–2026 when rates are higher would face minimal break costs (or zero).
Break costs depend entirely on the direction of interest rate movements since you fixed.
How to Get a Break Cost Quote
Contact your lender directly and ask for a “break cost estimate” or “economic cost estimate.” This is your right as a borrower — lenders must provide this figure.
Information to provide:
- Your loan account number
- The date you want to break (or approximate)
- The full or partial amount you want to repay
The lender provides a written estimate. This estimate is typically valid for a specific date and recalculated if you delay.
Strategies to Minimise Break Costs
1. Wait until your fixed term expires The most direct way to avoid break costs. Time your refinancing or sale to align with the end of your fixed period. Many lenders allow you to lock in a new rate 90 days before expiry.
2. Make only what your extra repayment limit allows If your fixed loan allows $20,000/year in extra repayments — use exactly that, no more.
3. Monitor interest rates If rates have risen significantly since you fixed, your break cost may be zero or very low — this is the time to refinance if you wish.
4. Check break costs before making any major decisions Always get a break cost quote before deciding to sell or refinance during a fixed period. The cost may make refinancing uneconomical.
Fixed Rate vs Variable — Break Cost Comparison
| Loan Type | Break Cost Risk | Flexibility |
|---|---|---|
| Fixed rate | High — can be tens of thousands | Low — limited extra repayments, no free exit |
| Variable rate | None — can repay anytime | High — full prepayment freedom |
| Split loan (part fixed, part variable) | Only on the fixed portion | Moderate |
Break Costs Are Not the Discharge Fee
When you exit a fixed loan early, you pay both:
- Fixed rate break cost (the economic cost — can be large)
- Standard discharge fee (administrative — typically $150–$400)

Frequently Asked Questions
How much can fixed rate break costs be? There is no upper cap. On a large loan with multiple years remaining and rates significantly below your fixed rate, break costs can be $20,000–$50,000+. Always get a quote before acting.
Can I avoid the break cost by staying with the same bank and switching products? Switching products within the same bank (variable to fixed, or one fixed product to another) during a fixed term still triggers a break cost — because the bank’s funding cost is unchanged.
Does LMI being paid on my loan affect break costs? No — break costs are calculated on the outstanding loan principal, regardless of how LMI was handled.
Are break costs tax deductible on investment loans? Break costs incurred in relation to an investment property loan may be deductible over 5 years or the remaining loan term. Consult a registered tax agent.
