How to Use Extra Repayments on Fixed Rate Loans

Most fixed rate home loans allow some level of extra repayments, but the cap is usually lower than you'd expect.

Malvern buyers often choose fixed rates for certainty during the first few years of ownership, particularly when purchasing in the area's established housing stock where purchase prices sit well above state medians. The question of whether you can pay down the loan faster while locked in comes up regularly, and the short answer is yes, but within limits set by each lender.

Fixed Rate Extra Repayment Limits

Most lenders cap extra repayments on a fixed rate loan at $10,000 to $30,000 per year without penalty. Go beyond that limit and you'll likely face break costs, which are calculated based on the difference between your fixed rate and the lender's current wholesale funding cost. If rates have dropped since you fixed, those costs can be substantial.

Consider a buyer who fixed a portion of their loan at 5.8% for three years. Eighteen months in, they receive an inheritance and want to put $60,000 toward the loan. If their lender allows $20,000 in annual extra repayments on the fixed portion, they could pay that amount without penalty, then redirect the remaining $40,000 to a variable rate portion if they have a split loan, or hold it in an offset account linked to the variable portion. Breaking the fixed term early to apply the full amount might cost several thousand dollars depending on rate movements.

Some lenders set their cap as a percentage of the original loan amount rather than a flat dollar figure, typically around 10% per year. Others don't allow any extra repayments at all on certain fixed products, particularly those offering the lowest rates. Checking the product disclosure statement before you lock in a rate tells you exactly what you're working with.

When a Split Loan Structure Works

A split loan lets you divide your borrowing between fixed and variable portions, giving you rate certainty on one part while keeping full flexibility on the other. Extra repayments go to the variable portion without restriction, and you can typically link an offset account to that portion as well.

In our experience with Malvern clients, a common split is 60% fixed and 40% variable. That structure protects most of the loan from rate rises while leaving enough room on the variable side to absorb windfalls, bonuses, or regular additional payments. If you're in a dual-income household with variable income streams, that flexibility can reduce your loan term significantly without exposing you to break costs.

The variable portion also gives you access to features that aren't available on most fixed products, including redraw facilities and portability. If you plan to sell and buy again within the fixed period, having a portable loan or the ability to move funds around becomes more valuable than squeezing the last tenth of a percent out of your fixed rate.

How Break Costs Are Calculated

Break costs apply when you pay more than the lender's annual cap or exit the fixed period early by selling, refinancing, or paying out the loan in full. The lender calculates the economic loss they incur by comparing your fixed rate to the rate they can now earn by relending that money in the wholesale market.

If you fixed at 5.8% and wholesale rates have since dropped to 4.5%, the lender has lost the opportunity to earn that higher rate for the remainder of your fixed term. They pass that loss to you as a break cost. The longer you have left on your fixed term and the bigger the rate gap, the higher the cost.

Some lenders calculate this daily, others use monthly averages. A few cap break costs at a certain number of months' interest, but most don't. Before making a large unscheduled payment or considering refinancing, ask your lender or broker for a break cost estimate. That figure can shift quickly with rate movements, so timing matters.

Extra Repayment Strategies That Don't Trigger Penalties

If you want to reduce your loan faster but don't want to risk break costs, there are a few approaches that work within the fixed rate structure. The first is to stay within the annual cap and make regular extra payments throughout the year rather than one lump sum. Paying an additional $1,500 per month on a loan with a $20,000 annual cap keeps you under the threshold while still chipping away at the principal.

Another option is to park surplus funds in an offset account linked to your variable portion if you have a split loan. The offset reduces the interest charged on that portion, which has the same effect as paying down the loan but keeps your cash accessible. For Malvern buyers managing ongoing costs related to period homes, including maintenance and occasional renovation work, liquidity can be more valuable than locking funds into the loan.

If you're on a fixed rate with no split and no offset, a high-interest savings account can serve as a holding strategy until your fixed term ends. You won't get the same tax treatment as an offset, but you'll earn some return while preserving the option to make a large payment once the fixed period expires and break costs no longer apply.

What Happens When Your Fixed Term Ends

When your fixed period finishes, your loan typically reverts to the lender's standard variable rate unless you take action. At that point, all repayment restrictions lift and you can pay as much as you want without penalty. It's also the cleanest time to refinance if you've found a more suitable product elsewhere.

Most lenders allow you to refix at a new rate within 30 to 90 days before your current fixed term ends. If you've been making extra repayments within the cap during the fixed period, your loan balance will be lower than originally scheduled, which means you're refixing a smaller amount and your repayments drop accordingly. If rates have risen in the meantime, you might choose to fix a smaller portion or move entirely to variable to regain flexibility.

We regularly see clients reach the end of a fixed term and realize they're no longer in the same financial position they were three or four years earlier. Income has increased, family circumstances have changed, or property goals have shifted. A loan health check around the time your fixed rate expires gives you a chance to restructure before you automatically roll onto a variable rate that may not suit your current situation.

Choosing the Right Fixed Rate Product

Not all fixed rate products are built the same way, and the lowest advertised rate often comes with the most restrictions. If you know you'll want to make extra repayments, prioritize products that allow at least $20,000 per year over those with slightly lower rates but no repayment flexibility.

Some lenders offer what they call "flexible fixed" products, which sit somewhere between a true fixed rate and a variable rate. These products allow higher caps on extra repayments or the ability to access redraw, but the rate is usually higher than a standard fixed product. Whether that trade-off makes sense depends on how much you expect to repay and how long you plan to hold the loan.

If you're buying in Malvern and expect to move within a few years, portability becomes more important than the absolute lowest rate. A portable loan lets you take your fixed rate with you to the next property without triggering break costs, as long as you're borrowing the same amount or more. Not all lenders offer this feature, and those that do often restrict it to owner-occupied loans.

Call one of our team or book an appointment at a time that works for you. We'll compare products across multiple lenders and show you exactly what each option allows in terms of extra repayments, break costs, and flexibility, so you can lock in a rate without locking yourself into a structure that doesn't fit.
