What Are Break Costs on an Investment Loan?
Break costs are the fee a lender charges when you exit a fixed rate loan before the fixed term ends. The amount depends on how much the wholesale interest rate has moved since you locked in your rate. If wholesale rates have fallen since you fixed, you'll usually owe the lender the difference between what they expected to earn and what they can now earn on that money over the remaining term.
Consider a property investor who fixed an investment loan at 5.2 per cent for three years. Eighteen months into the term, variable rates drop and they want to refinance to a lower rate or sell the property. The lender will compare their original fixed rate to the current wholesale rate for the remaining eighteen months. If the current rate is lower, the investor compensates the lender for the lost interest income. Break costs in this scenario could be several thousand dollars, depending on the loan amount and rate movement.
Lenders don't publish a single formula, but most use a present value calculation based on the difference between your fixed rate and the current wholesale funding cost for the remaining fixed period. The larger your loan amount and the longer the remaining term, the higher the potential break cost. Some lenders also charge an administration fee on top of the calculated amount.
How Rate Lock-ins Work for Property Investors
A rate lock-in allows you to secure a fixed interest rate before settlement, typically for 90 days. You apply for the loan, the lender approves it, and you nominate a fixed rate from the current rate card. The lender then holds that rate for you until settlement, even if rates rise in the meantime. If rates fall before settlement, you're locked into the higher rate unless the lender offers a one-time refix option.
Rate locks are particularly relevant for investors buying off-the-plan or building new investment property, where settlement may be months away. Locking protects you from rate rises during construction, but it also removes flexibility. If you lock at 5.8 per cent and rates drop to 5.3 per cent before settlement, you'll start the loan at the higher rate. Some lenders allow a single rate reduction if their published rates drop, but not all do, and the process varies by institution.
In our experience, investors who lock rates tend to do so when the Reserve Bank commentary suggests upward pressure. If economic signals point to rate cuts or stability, most borrowers wait until closer to settlement. The risk of locking too early is that you pay more than necessary from day one. The risk of not locking is that rates rise and your serviceability tightens or disappears.
Why Investors Choose Fixed Rates Despite Break Costs
Fixed rates give you certainty over repayments, which matters when you're managing rental income and vacancy risk. An investment loan with a fixed rate means you know exactly what your holding costs will be for the fixed period, regardless of Reserve Bank movements. For negatively geared investors, predictable repayments make budgeting simpler and reduce the risk of cashflow stress if variable rates spike.
Fixed rates also allow you to lock in borrowing capacity. Lenders assess your serviceability using a buffer above the loan rate. When you apply for an investment loan, the lender tests whether you can service the loan at the product rate plus the serviceability buffer, which is currently 3.0 percentage points. If you fix at a lower rate and variable rates rise, your existing fixed loan repayments stay the same, which can preserve equity release capacity or borrowing power for a second property.
The trade-off is rigidity. If you need to sell the property, refinance for a lower rate, or pay down the loan faster than the agreed repayment schedule, you'll likely trigger break costs. Investors who plan to hold the property long-term and value stable repayments over flexibility tend to favour fixed rates. Those who anticipate portfolio changes or expect rates to fall typically stick with variable or split their loan.

Calculating Break Costs When You Exit Early
Break costs are calculated by comparing the interest rate you're locked into with the lender's current wholesale funding cost for the remaining term. The lender is effectively asking you to cover the loss they incur by no longer receiving your higher fixed interest payments. If you're paying 5.5 per cent fixed and the lender can only reinvest that money at 4.8 per cent for the remaining period, you'll owe the difference multiplied by your loan amount and adjusted for the time remaining.
Most lenders provide a break cost estimate over the phone or through their online portal. The estimate changes daily as wholesale rates move. Some lenders cap break costs at a percentage of the outstanding balance, while others calculate purely on rate differential. Administration fees, typically a few hundred dollars, may also apply. If wholesale rates have risen since you fixed, the break cost may be zero, or the lender may even apply a clawback, though not all lenders pass this benefit to the borrower.
It's worth requesting a formal break cost estimate before committing to refinance or sell. Refinancing to save 0.3 per cent on your rate won't make sense if the break cost is $8,000 and you'd need three years to recover that cost through lower repayments. On the other hand, if you're selling the property regardless, the break cost becomes a sunk cost that reduces your net sale proceeds.
Split Rate Strategies That Reduce Break Cost Risk
Splitting your investment loan between fixed and variable portions gives you both stability and flexibility. A common approach is to fix half the loan and leave half variable. The fixed portion protects you from rate rises, while the variable portion lets you make extra repayments, redraw if needed, or refinance part of the loan without triggering break costs on the entire balance.
Consider an investor with a $600,000 investment loan who fixes $300,000 for three years and keeps $300,000 variable. If they decide to sell the property two years into the term, they'll only pay break costs on the $300,000 fixed portion, not the full $600,000. The variable portion can be discharged without penalty. If they want to refinance for a lower rate, they can refinance the variable portion immediately and decide whether the break cost on the fixed portion justifies refinancing that half as well.
Some investors split unevenly, fixing 60 or 70 per cent and leaving the rest variable, depending on their risk tolerance and cashflow needs. The variable portion also allows you to take advantage of offset accounts, which most fixed rate products don't offer. Splitting doesn't eliminate break costs, but it reduces the amount at risk and gives you more options if your circumstances change mid-term.
When Break Costs Are Worth Paying
There are situations where paying a break cost makes sense. If you're locked into a fixed rate well above current variable rates and you have several years remaining on the fixed term, the interest savings from refinancing may outweigh the upfront break cost. Run the numbers by comparing the total interest you'll pay over the remaining fixed term against the break cost plus the interest you'd pay on a new variable loan over the same period.
Break costs also become unavoidable if you need to sell the property. In that case, the break cost is simply part of the transaction cost, like conveyancing or agent fees. If selling allows you to reallocate capital to a higher-performing investment or relieves financial pressure, the break cost is secondary to the broader outcome. Similarly, if you're consolidating debt or accessing equity for a deposit on another property, the break cost may be justified by the financial restructure you're enabling.
If the break cost is minor because rates have moved in your favour or you're near the end of the fixed term, it's almost always worth proceeding with your intended change. Where the break cost is substantial and you're still early in the fixed period, weigh it carefully against your reason for exiting. One specific insight we regularly see: investors who fixed at the peak of a rate cycle often benefit from refinancing even with a break cost, because the rate differential over the remaining term outweighs the penalty.
Variable Rates and the Flexibility Trade-Off
Variable rate investment loans don't carry break costs, which gives you complete flexibility to refinance, sell, or make extra repayments whenever you choose. Variable rates also allow full access to offset accounts, which can reduce the interest you pay without formally reducing the loan balance. For investors who want to maximise tax deductions while minimising actual interest costs, an offset account on a variable loan is a common structure.
The downside is repayment uncertainty. Variable rates move in response to Reserve Bank decisions and competitive pressure among lenders. If rates rise, your repayments increase, which affects your cashflow and may reduce the amount of rental income you retain after covering the mortgage. Investors with tight cashflow or multiple properties sometimes find that a sharp rate rise tips their portfolio from manageable to stressful.
Variable rates also shift your borrowing capacity. If you're planning to buy a second investment property in the near term, rising variable rates on your existing loan reduce your serviceability for the new loan. Fixing at least part of your investment loan can lock in borrowing capacity by keeping existing repayments stable, even if rates rise before you apply for the next loan. The choice between variable and fixed comes down to whether you value flexibility or certainty more highly given your current portfolio and plans.
What Happens During Financial Hardship
If you're unable to meet your repayments on a fixed rate investment loan, you can request a hardship arrangement under the National Credit Code. The lender is required to consider your notice and respond within a set timeframe. Hardship arrangements can include repayment deferrals, temporary interest-only periods, or extending the loan term to reduce repayments. However, hardship provisions don't typically waive break costs if you want to exit a fixed rate loan as part of the arrangement.
Some lenders may allow you to switch from fixed to variable under hardship without charging a break cost, but this is discretionary and not guaranteed. If the hardship arrangement involves selling the property, the break cost will usually still apply, though it may be negotiable depending on your circumstances and the lender's policy. It's worth raising the break cost issue explicitly when you lodge a hardship notice, as some lenders have internal guidelines that allow concessions in genuine hardship cases.
For investors holding multiple properties, hardship becomes more complex. The lender may assess your entire portfolio and income position, not just the single property in question. If rental income has dropped due to vacancy or rental market softness, document that clearly in your hardship notice. Lenders generally respond more constructively when you provide evidence and a realistic proposal, rather than waiting until you've missed payments.

Frequently Asked Questions
What are break costs on a fixed rate investment loan?
Break costs are the fee a lender charges when you exit a fixed rate loan early. The amount is based on the difference between your fixed rate and the lender's current wholesale funding cost for the remaining term. If rates have fallen since you fixed, you compensate the lender for lost interest income.
How does a rate lock-in work for an investment property loan?
A rate lock-in lets you secure a fixed rate before settlement, usually for 90 days. The lender holds that rate for you even if rates rise before settlement. If rates fall, you're typically locked into the higher rate unless the lender offers a one-time refix option.
Can I avoid break costs by splitting my investment loan?
Splitting your loan between fixed and variable portions reduces break cost risk but doesn't eliminate it. You'll only pay break costs on the fixed portion if you exit early, while the variable portion can be refinanced or discharged without penalty. This gives you both stability and flexibility.
When are break costs worth paying on an investment loan?
Break costs may be worth paying if you're locked into a high fixed rate with years remaining and current rates are much lower. Compare the total interest saved by refinancing against the upfront break cost. Break costs are also unavoidable if you need to sell the property or restructure your debt.
Do break costs apply if I'm in financial hardship?
Break costs usually still apply during hardship, though some lenders may waive them on a case-by-case basis if you're switching to a hardship arrangement or selling the property. Raise the issue explicitly when you lodge your hardship notice, as some lenders have concession policies for genuine hardship cases.
