Unlock the secrets to rate lock-ins and break costs

Fixed rate break costs explained

Break costs are fees charged by lenders when you exit a fixed rate loan before the fixed term ends. The fee compensates the lender for the difference between the rate you agreed to and the rate the lender can now earn by lending that money elsewhere. If rates have fallen since you locked in, the break cost can run into thousands of dollars.

Consider a buyer who fixed $500,000 at 5.8% for three years in mid-2024. Eighteen months later, rates have dropped to 4.9%. The lender calculates the difference between what they expected to earn from your loan and what they can now earn by re-lending that money at current rates, then multiplies that loss across the remaining fixed term. In this scenario, the break cost could reach $12,000 to $15,000, depending on the lender's calculation method.

Not all lenders calculate break costs the same way. Some use wholesale swap rates, others use their own internal funding costs, and a few cap break costs at a percentage of the outstanding loan balance. Defence Loans works with lenders who use different calculation methods, which matters when you need to move before the fixed term ends.

When break costs apply

Break costs apply whenever you pay off or refinance a fixed rate loan before the fixed period expires. Selling your home, refinancing to a lower rate, or switching lenders all trigger the calculation. Paying extra off the loan during the fixed term can also trigger break costs if your loan does not include a partial repayment option.

Posting cycles create pressure points. An ADF member posted from Puckapunyal to Townsville 18 months into a three-year fixed rate might need to sell. If rates have fallen in that time, the break cost adds directly to the cost of relocating. The lender does not waive the fee because of a posting, and the break cost is due at settlement whether you are refinancing or selling.

Some fixed rate loans allow up to $10,000 or $20,000 in extra repayments each year without penalty. That flexibility helps if you receive a posting allowance or bonus and want to reduce the loan balance, but it does not remove break costs if you exit the loan entirely. Low deposit loans for ADF members often include fixed rate options, and understanding the break cost terms matters as much as the interest rate itself.

Split loans reduce exposure

A split loan divides your borrowing between fixed and variable portions. You might fix 50% of the loan and leave 50% on a variable rate, or use a 60/40 or 70/30 split depending on your circumstances. The variable portion gives you flexibility to make extra repayments or exit without penalty, while the fixed portion provides rate certainty on part of the loan.

An ADF member borrowing $450,000 might fix $225,000 for three years and leave $225,000 on a variable rate with an offset account. If they are posted two years later and need to sell, the break cost only applies to the fixed portion. The variable portion can be paid out or refinanced without penalty. The offset account on the variable portion also lets them park any savings and reduce interest without triggering break costs.

Split loans work well for buyers who want some protection from rate rises but need flexibility for postings or life changes. The fixed portion limits how much interest rate movement affects your repayments, and the variable portion keeps options open. Lenders do not charge extra fees to set up a split loan, and you can choose the proportions that suit your situation.

Victoria stamp duty concessions for first home buyers

Victoria provides a full stamp duty exemption on properties up to $600,000 for eligible first home buyers. A sliding scale concession applies to properties valued between $600,001 and $750,000, phasing out completely above that threshold. The concession applies to both new and established homes, provided the property is your principal place of residence.

An ADF member purchasing in Geelong or Ballarat at current median values would likely qualify for full or partial duty relief, depending on the property price. The exemption can save between $10,000 and $30,000, which reduces the upfront cash required at settlement. First home buyers using the 5% deposit scheme can combine the stamp duty concession with the federal guarantee, meaning no lenders mortgage insurance and reduced duty in the same transaction.

The Victorian First Home Owner Grant of $10,000 applies only to new homes valued up to $750,000. It does not apply to established properties. If you are buying land and building, or purchasing a newly constructed home, you may qualify for both the grant and the stamp duty concession, depending on the total property value.

Fixed rate lock-in periods

Most lenders offer fixed rate terms from one to five years. Shorter fixed terms reduce the period you are locked in, which lowers the risk of large break costs if you need to exit early. Longer fixed terms provide more certainty but increase exposure if your circumstances change.

A one-year fixed rate suits buyers who expect a posting or life change within 12 to 18 months. A three-year fixed rate suits buyers who want stability through the early years of ownership. Five-year fixed rates appeal to buyers who want long-term certainty, but those loans carry the highest break cost risk because more time remains if rates fall and you need to exit.

Rate lock periods also matter. Once you apply for a fixed rate loan, the lender locks in the rate for a set period, usually 90 days. If settlement occurs within that window, you get the locked rate. If settlement is delayed beyond the lock period, the rate may change, and you might need to accept a higher rate or walk away. Getting loan pre-approval helps clarify timing and reduces the risk of losing a locked rate before settlement.

Variable rate features that fixed loans do not offer

Variable rate loans include features that fixed rate loans do not. Offset accounts let you park savings in a linked account and reduce the interest charged on your loan balance without making extra repayments. Redraw facilities let you access extra repayments you have made, though some lenders restrict redraw frequency or charge fees.

Fixed rate loans rarely include full offset accounts. Some lenders offer partial offsets on fixed loans, where only 40% or 60% of the linked balance offsets the loan interest. Others offer no offset at all during the fixed period. If you expect to hold cash savings while paying off your loan, a variable rate or a split loan with an offset on the variable portion usually works better.

You can also make unlimited extra repayments on most variable rate loans without penalty. Fixed loans cap extra repayments or charge break costs if you exceed the annual limit. For ADF members who receive irregular lump sums from allowances, postings, or deployments, the flexibility of a variable rate can outweigh the certainty of a fixed rate.

Refinancing a fixed rate loan

Refinancing a fixed rate loan before the term ends triggers break costs unless rates have risen since you locked in. If rates have risen, the lender may calculate a break cost of zero or even a break gain, which they typically do not refund. Refinancing to secure a lower rate only makes financial sense if the interest savings over the remaining loan term exceed the break cost and refinancing fees.

An ADF member with two years remaining on a fixed rate of 6.2% might see variable rates advertised at 5.4%. The interest saving over two years on a $400,000 loan could reach $6,500, but if the break cost is $8,000, refinancing leaves you worse off. Running the numbers with a broker before applying avoids wasting time on applications that do not improve your position.

Home loan refinancing for ADF members often involves reviewing fixed rate break costs, comparing them against potential savings, and deciding whether to wait until the fixed term expires or move sooner. Lenders provide break cost estimates on request, and those estimates are usually valid for a short period before rates or circumstances change.
