Fixed rates feel like a safety net until they're not.
When you lock in a rate, you're making a bet on where the market's headed, and if you need to break that contract early or don't plan for what happens when it expires, the costs can sting. Around Norah Head, where a lot of homeowners locked in low rates a few years back, plenty are now facing either eye-watering break fees or sudden jumps to higher variable rates. The thing to understand is this: break costs aren't penalties, they're compensation to the lender, and the calculation behind them is tied directly to what's happened in the wholesale rate market since you locked in.
How a Rate Lock Actually Works
When you fix your interest rate, the lender borrows money at a wholesale rate and locks that cost for the term you've chosen. You agree to pay a set rate for one, two, three, or sometimes five years. During that period, your repayments don't move, no matter what happens with the Reserve Bank or variable rates. That's the upside. The downside is you're committed. If you want to sell, refinance, or pay down a big chunk of the loan before that term ends, the lender calculates what they lose by letting you out early. That's your break cost.
The calculation compares the rate you're locked into with the current wholesale rate for the remaining term. If rates have gone up since you fixed, there's usually no break cost because the lender can re-lend that money at a higher rate. If rates have dropped, you're on the hook for the difference.
What You Pay to Break a Fixed Rate Early
Break costs are worked out using the difference between your fixed rate and the lender's current cost to borrow money for the time left on your fixed term. If you fixed at 2.5% for three years and rates are now sitting closer to 6%, you're probably fine. If you fixed at 2.5% and wholesale rates dropped to 2%, you'll be charged the lender's lost interest over the remaining period.
Consider a buyer in Norah Head who fixed a loan at 2.3% during the pandemic on a property near Soldiers Beach. Two years into a three-year fix, they decided to sell and move closer to family in Newcastle. Rates had climbed, so the break cost came back at zero. If that same scenario had played out six months earlier when rates were still low, the cost could have been several thousand dollars. Timing matters, and so does understanding what you signed up for.
Some lenders let you port your loan to a new property, which can help you avoid break costs if you're upgrading or relocating. Others don't. That's worth checking before you lock in, not after you've accepted an offer on your place.
What Happens When Your Fixed Term Ends
Most fixed rate home loans revert to the lender's standard variable rate when the term expires. That rate is almost always higher than the discounted variable rate you'd get as a new customer, and it's definitely higher than the fixed rate you've been paying if you locked in a few years ago. If you do nothing, your repayments jump, sometimes by hundreds of dollars a month.
Lenders are required to notify you before your fixed term ends, but they're not required to offer you a better deal. That's on you to organise. Around Norah Head, where a lot of homeowners have seen property values hold steady around the beachside pockets near the lighthouse and Toowoon Bay, refinancing before the fixed term ends usually makes sense. It gives you time to compare rates across lenders and avoid the revert rate entirely.

The Split Strategy That Keeps Your Options Open
A split loan lets you fix part of your home loan and keep the rest on a variable rate. It's not a perfect hedge, but it does mean you're not locked in completely. If rates drop, the variable portion benefits. If they rise, the fixed portion protects you. You also keep access to an offset account on the variable portion, which most fixed loans don't allow.
In our experience, clients around Norah Head who went with a 50/50 split had more flexibility when life changed. One scenario involved a local buyer who split evenly between fixed and variable on an owner occupied home loan. When they received an inheritance halfway through the fixed term, they paid down the variable portion without triggering any break cost. The fixed portion stayed in place, keeping half their repayments stable. If the whole loan had been fixed, they'd have either paid a break cost or missed the chance to reduce debt while rates were climbing.
Splits don't suit everyone. If you're stretching to afford repayments, locking in the whole amount might make more sense because you need the certainty. But if you've got some breathing room and want to keep your options open, a split is worth considering. You can usually adjust the ratio to suit your situation, whether that's 70/30, 60/40, or something else.
When Breaking Early Actually Makes Sense
Break costs aren't always a dealbreaker. If refinancing saves you enough over the remaining term to cover the cost and still come out ahead, it's worth doing. That usually happens when your current lender's rate is well above what you can get elsewhere, or when you're paying Lenders Mortgage Insurance on your existing loan and your property value has increased enough to remove it.
Before you refinance, get the break cost in writing. Lenders are required to give you an estimate, and the final figure shouldn't be far off. Compare that against what you'll save by switching, including any rate discounts, fee waivers, or offset benefits the new lender is offering. If the numbers don't stack up, wait until your fixed term ends and refinance then. If they do, move quickly because rate discounts don't stick around forever.
Portable Loans and Other Ways to Avoid Break Costs
Some lenders offer portable loans, which let you transfer your existing fixed rate to a new property if you're selling and buying at the same time. It's not common, but it exists. The catch is you usually need to borrow the same amount or more, and settlement dates have to align. If you're downsizing or there's a gap between selling and buying, portability won't help.
Another option is to keep the fixed loan in place and take out a second loan for the new property, then close the first one when the fixed term ends. That works if you can service both loans temporarily and if your borrowing capacity allows it. It's clunky, but it avoids the break cost.
If you're planning to sell within a few years, don't lock in for longer than you need. A one-year fix gives you certainty without tying you down. A five-year fix might look appealing when rates are low, but it's a long time to stay committed, especially if your circumstances might change.
Reading the Fine Print Before You Lock In
Not all fixed rate home loan products are the same. Some let you make extra repayments up to a certain amount each year without penalty. Others don't allow any extra repayments at all. Some include an offset account, most don't. Some let you switch to variable early if you're willing to pay the break cost, others make it harder.
Before you lock in, ask about break cost calculations, portability, extra repayment limits, and what rate you'll revert to when the term ends. If you're buying in Norah Head and you're planning to renovate, upsize, or relocate in the next few years, a fixed rate might not be the right fit unless you're splitting the loan or going with a shorter term.
The other thing to watch is rate discounts that only apply during the fixed term. Some lenders advertise a low fixed rate but revert you to a high variable rate with no ongoing discount. That's fine if you're planning to refinance when the term ends anyway, but if you're hoping to set and forget, it'll cost you.

We'll run the numbers, check what break costs might apply, and help you figure out whether locking in, splitting, or staying variable makes sense for where you're at.
Frequently Asked Questions
What is a break cost on a fixed rate home loan?
A break cost is the amount you pay to exit a fixed rate home loan before the term ends. It's calculated based on the difference between your locked rate and the lender's current wholesale rate for the remaining period. If rates have risen since you fixed, the break cost is usually zero.
What happens when my fixed rate term ends?
When your fixed term ends, your loan reverts to the lender's standard variable rate, which is typically higher than discounted rates offered to new customers. You'll receive notice before the term expires, but it's up to you to refinance or negotiate a new rate to avoid higher repayments.
Can I avoid break costs if I need to sell my property?
You may avoid break costs if rates have increased since you fixed, as the lender can re-lend at a higher rate. Some lenders also offer portable loans that let you transfer your fixed rate to a new property, though settlement timing and loan amounts must align.
What is a split loan and how does it help?
A split loan divides your home loan between a fixed portion and a variable portion. This gives you some rate stability while maintaining flexibility to make extra repayments or benefit from rate drops on the variable portion. It also usually allows access to an offset account on the variable side.
Should I fix my home loan for one year or five years?
It depends on how long you plan to stay in the property and your need for certainty. A shorter fixed term gives you flexibility if your circumstances might change, while a longer term locks in your rate but commits you for longer. If you might sell or refinance within a few years, a shorter term or split loan is usually safer.
