A fixed rate home loan locks in your interest rate for a set period, usually between one and five years.
That certainty comes with a condition: if you exit the loan before the fixed term ends, whether through refinancing, selling the property, or paying down a large lump sum, the lender may charge break costs to recover the funding difference between the rate you locked in and the rate they can now lend that money at.
How Break Costs Are Calculated
Break costs reflect the economic loss your lender incurs when you exit a fixed rate contract early. The lender originally borrowed the funds at a wholesale rate tied to your fixed term and must now re-lend or place those funds at a lower rate if market rates have fallen since you locked in.
The calculation typically compares the interest rate on your fixed loan with the current wholesale rate for the remaining fixed term, multiplied by the outstanding loan amount and adjusted for the time remaining. If rates have increased since you fixed, break costs are usually zero because the lender can re-lend at a higher rate. If rates have fallen, the cost can be substantial.
Consider a borrower who fixed $600,000 at 5.8% for three years in late 2023. By mid-2026, with eighteen months remaining on the fixed term, wholesale rates had dropped to around 4.2%. The lender calculates the difference of 1.6 percentage points across the remaining term on the outstanding balance, discounted to present value. In this scenario, break costs could reach $14,000 or more, depending on the lender's methodology and the exact wholesale rate used.
When Break Costs Apply in Mount Waverley
Break costs are triggered anytime you alter or exit a fixed rate home loan before the term ends. That includes refinancing to a lower rate, selling your home, or making a partial prepayment that exceeds your loan's annual allowance.
Many lenders allow prepayments of up to $10,000 or $20,000 per year without penalty, but anything beyond that threshold will attract break costs if you're still within the fixed period. Switching from interest-only to principal and interest repayments within the same loan usually does not trigger break costs, but moving the loan to a different lender or product will.
In Mount Waverley, where median house prices sit comfortably within the Australian Government 5% Deposit Scheme cap of $950,000 for capital cities and regional centres in Victoria, many buyers entering the market with smaller deposits choose split rate structures to balance certainty and flexibility. A borrower fixing half the loan avoids break costs on the variable portion if circumstances change, while still securing a portion of the debt against rate rises.

Portability and Its Limits
Some lenders offer portable fixed rate loans, allowing you to transfer the existing fixed rate contract to a new property without triggering break costs. Portability can be valuable if you're upgrading or relocating within the fixed term, particularly in areas like Mount Waverley where families often move from apartments near Jordanaire or Syndal stations to larger family homes closer to Mount Waverley Primary School or the Valley Reserve precinct as household size grows.
Portability is not automatic. The new property must be approved as security by the lender, and if you're borrowing additional funds beyond the existing loan balance, the extra amount will be priced separately at current rates. You also cannot reduce the loan amount below the original fixed balance without triggering break costs on the portion being repaid.
If the new property falls outside the lender's lending policy, or if your financial circumstances have changed in a way that affects serviceability, the lender may decline to port the loan, forcing you to refinance and incur break costs regardless of portability terms.
Split Rate Structures and How They Work
A split rate loan divides your borrowing into two or more portions: one fixed, one variable, or multiple fixed terms at different rates and durations. Each portion operates independently, with its own interest rate, repayment schedule, and terms.
Splitting allows you to fix a portion of the debt for certainty while keeping the rest variable for flexibility. The variable portion can be reduced with lump sum repayments at any time without penalty, and if you refinance or sell, break costs apply only to the fixed portion based on the amount and term still locked.
In a scenario where a Mount Waverley buyer borrows $700,000 to purchase near Pinewood Shopping Village, fixing $400,000 at 5.5% for three years and leaving $300,000 variable at 6.2%, the borrower can make extra repayments or redraw from the variable portion without restriction. If they sell eighteen months later when rates have fallen to 4.8%, break costs are calculated only on the $400,000 fixed portion for the remaining eighteen months, potentially reducing the total cost compared to fixing the entire loan amount.
Break Cost Estimates and Disclosure
Lenders are required to provide an estimate of break costs on request, and many will do so before you commit to exiting the loan. The estimate is calculated using the lender's wholesale funding rate at the time of the request and the remaining term on your fixed contract.
Break cost estimates are not binding and will change daily as wholesale rates move. If you're considering refinancing or selling, request an estimate as close as possible to your intended settlement date, and factor in the possibility that the final figure could be higher or lower depending on rate movements in the intervening period.
Some lenders include a break cost calculator in their online banking portal, allowing you to generate an estimate without calling. The calculator uses the same formula the lender applies at discharge, though it may not account for all fees or adjustments, so treat it as indicative rather than final.
Offset Accounts and Why They Don't Reduce Break Costs
An offset account linked to a variable rate loan reduces the interest charged by offsetting your savings balance against the outstanding loan amount. Offset accounts on fixed rate loans, where available, operate differently and do not reduce the interest rate or the balance used to calculate break costs.
If you hold $50,000 in an offset account linked to a $500,000 fixed rate loan, the lender still calculates break costs on the full $500,000, not the net $450,000. The offset balance does not alter the fixed rate contract or the funding position the lender holds for that loan.
For borrowers prioritising flexibility and the ability to reduce debt without penalty, a variable rate loan with a full offset is typically more effective than a fixed rate product with a partial offset, particularly if you expect to receive irregular income or bonuses that you want to apply toward the loan without triggering costs.
What Happens If You Do Nothing
If your fixed term expires and you do not contact your lender or broker, the loan will automatically revert to the lender's standard variable rate. This rate is almost always higher than the lender's current discounted variable rate available to new or refinancing borrowers, sometimes by 0.5 to 1.0 percentage points or more.
Reverting to the standard variable rate means you're likely paying more than necessary, and you forfeit any rate discounts, offset functionality, or features available on other products within the same lender's range. Reviewing your loan at least sixty days before the fixed term ends gives you time to negotiate a new rate, switch products, or refinance to a different lender without incurring break costs.

Frequently Asked Questions
What are break costs on a fixed rate home loan?
Break costs are charges applied by lenders when you exit a fixed rate loan before the term ends. They reflect the economic loss the lender incurs when market rates have fallen and the lender must re-lend your funds at a lower rate than originally locked in.
When do break costs apply?
Break costs apply when you refinance, sell your property, or make large lump sum repayments beyond your annual allowance during a fixed rate term. They are usually zero if rates have risen since you fixed, but can be significant if rates have fallen.
Can I avoid break costs with a portable loan?
Some lenders allow you to transfer a fixed rate contract to a new property without triggering break costs, but portability is not automatic. The new property must meet lending criteria, and you cannot reduce the loan balance without incurring costs on the portion repaid.
How do split rate loans reduce break cost risk?
A split rate loan divides your borrowing into fixed and variable portions. Break costs apply only to the fixed portion if you exit early, and you can make extra repayments on the variable portion without penalty at any time.
Do offset accounts reduce break costs on fixed rate loans?
No. Break costs are calculated on the full outstanding fixed loan balance, regardless of any offset account balance. Offset accounts linked to fixed loans do not reduce the balance used in the break cost calculation.
