Most lenders cap how much you can repay on a fixed rate loan each year before penalties kick in.
If you're weighing up a fixed interest rate as a first home buyer in Victoria, understanding how extra repayments work could save you thousands in fees and keep your loan flexible when you need it most. The appeal of locking in certainty is strong, but the rules around repaying more than your minimum are often misunderstood until it's too late.
Fixed Rate Repayment Caps: How Much Can You Actually Pay?
Most lenders allow extra repayments of up to $10,000 to $30,000 per year on a fixed rate home loan without penalty. Exceed that limit and you'll be charged break costs, which can run into thousands depending on how much rates have moved since you fixed. The cap resets each year, so if you pay an extra $15,000 in year one and your cap is $20,000, you start fresh the following year with another $20,000 available.
Consider a buyer who fixes $450,000 at a set rate for three years with a $20,000 annual repayment cap. They plan to put any bonuses or overtime towards the loan. In the first year they add $18,000, staying under the limit. In year two, they receive a $35,000 inheritance and want to throw it all at the mortgage. If they deposit the full amount, they'll pay break costs on the $15,000 over the cap. Instead, they pay $20,000 immediately and park the remaining $15,000 in a high-interest savings account, then apply it the following year when the cap resets. That approach costs nothing in penalties and still reduces interest over time.
Split Loans: Keeping One Foot in Each Door
A split loan divides your borrowing between a fixed and variable portion, giving you the certainty of a locked rate while keeping access to features like unlimited extra repayments and an offset account on the variable side. This structure works well if you expect irregular income or want to chip away at the principal without worrying about caps.
In our experience, first home buyers using the First Home Guarantee with a smaller deposit often split 50/50 or go 60% fixed and 40% variable. The variable portion absorbs extra repayments, and the fixed portion shields you from rate rises. You'll still avoid Lenders Mortgage Insurance (LMI) under the scheme, and the flexibility means you can adjust your repayment strategy as your income changes without penalties.
Redraw vs Offset: What You Get on a Fixed Loan
Fixed rate loans rarely come with an offset account. Instead, lenders usually offer a redraw facility, which lets you access any extra repayments you've made above the minimum, provided you stay within the annual cap. The difference matters because an offset account reduces the interest you're charged daily without technically paying down the loan, while redraw pulls money back out after you've already reduced the principal.
If you fix the whole loan and later need access to cash for renovations or an emergency, redraw gives you that option as long as the lender hasn't restricted it. Some lenders charge a fee per redraw or set a minimum withdrawal amount, so check the terms before you commit. On a variable loan or the variable portion of a split, an offset account usually works better because the funds stay separate, you can access them anytime, and they still reduce your interest.
How Break Costs Are Calculated and When They Apply
Break costs are charged when you repay more than your annual cap, refinance, or sell during the fixed period. The fee compensates the lender for the difference between the rate you locked in and the rate they can now lend that money at. If rates have dropped since you fixed, the cost can be significant. If rates have risen, the break cost may be zero or negligible.
The calculation is opaque and varies between lenders, but it's based on the amount you're repaying early, how much time is left on the fixed term, and the movement in wholesale interest rates. As an example, if you fixed $400,000 two years ago and want to refinance with 18 months remaining, and rates have fallen, you might face a break cost of $8,000 to $12,000. That often wipes out any benefit from switching to a lower rate, which is why most borrowers wait until the fixed term expires unless circumstances force a sale.
Using the First Home Super Saver Scheme Alongside a Fixed Loan
If you've used the First Home Super Saver Scheme to build your deposit, you've already saved tax by contributing inside super. Once you withdraw those funds for your deposit and settle on the property, your focus shifts to loan structure. A fixed rate loan with a repayment cap still benefits from any lump sums you can put towards it annually, and pairing that with a split loan structure means you can direct smaller ongoing payments to the variable side while using your annual cap on the fixed portion for bigger one-off contributions.
This approach works well if you're still building savings momentum after using a chunk of your super for the deposit. You're not locked into one repayment pattern, and you can adjust as your financial position improves without triggering penalties.
Refinancing Before Your Fixed Term Ends: When It Makes Sense
Refinancing during a fixed term almost always incurs break costs unless rates have moved in your favour or your lender waives the fee as part of a retention offer. For most first home buyers, it makes more sense to wait until the fixed period expires, then reassess your options. If your circumstances change dramatically, such as a big income increase, inheritance, or sale due to relocation, the break cost might be worth paying to access better features or a lower rate elsewhere.
Before you make that call, ask your current lender for a break cost estimate in writing. Compare that figure against the potential savings from a new loan structure, factoring in any pre-approval or application fees with the new lender. In many cases, the numbers don't stack up until you're within six months of the fixed term ending, at which point the break cost shrinks and refinancing becomes viable.
Preparing for Fixed Rate Expiry: What Happens Next
When your fixed term ends, your loan will automatically revert to the lender's standard variable rate unless you take action. That reversion rate is often higher than the variable rate offered to new customers, so it's worth reviewing your options at least three months before expiry. You can fix again, switch to variable, negotiate a discount with your current lender, or refinance elsewhere.
If you've been making extra repayments within your annual cap and using redraw when needed, your loan balance will be lower than it would have been on minimum repayments alone. That puts you in a stronger position when negotiating or refinancing, and you may qualify for a better rate or access to features like an offset account that weren't available on the original fixed loan. Our fixed rate expiry page walks through the process and what to prepare.
Understanding how fixed rate loans handle extra repayments before you sign up means you can structure your borrowing to suit how you actually manage money, not just how you think you will.

Frequently Asked Questions
Can I make extra repayments on a fixed rate home loan?
Yes, but most lenders cap the amount you can repay each year without penalty, usually between $10,000 and $30,000. If you exceed that limit, you'll be charged break costs. The cap resets annually.
What is a split loan and why would a first home buyer use one?
A split loan divides your borrowing between fixed and variable portions. The fixed part gives you rate certainty, while the variable side allows unlimited extra repayments and access to an offset account, giving you flexibility without penalties.
What are break costs and when do they apply?
Break costs are fees charged when you repay more than your annual cap, refinance, or sell during a fixed term. They compensate the lender for the difference between your locked rate and current rates, and can be significant if rates have dropped since you fixed.
Should I refinance before my fixed rate term ends?
Usually not, unless your circumstances have changed dramatically. Refinancing during a fixed term almost always triggers break costs, which often outweigh any savings from a new loan. It's generally better to wait until the fixed period expires.
What happens when my fixed rate loan expires?
Your loan will automatically revert to the lender's standard variable rate, which is often higher than rates for new customers. Review your options at least three months before expiry to fix again, switch to variable, negotiate a discount, or refinance elsewhere.
