Common Mistakes with Fixed Rate Loans and Extra Repayments

Fixed Rates and Extra Repayments: What You Can Actually Do

Most fixed rate home loans allow extra repayments up to a set annual limit, typically between $10,000 and $30,000 depending on the lender and product. Once you exceed that limit, break costs apply.

The confusion usually starts when buyers assume a fixed rate loan locks them out of paying extra entirely. In our experience, people who have been putting money into an offset against a variable rate often worry they will lose all flexibility if they fix. The reality is different. Consider a buyer refinancing from a full variable structure into a three-year fixed rate with a $20,000 annual extra repayment allowance. They were previously putting $400 a week into offset. Under the fixed structure, they can still contribute $384 per week without hitting the annual cap, which preserves nearly all of their existing payment behaviour while securing a known rate.

The limit resets each year on the anniversary of settlement. If you make $15,000 in extra repayments in year one and your annual limit is $20,000, you start fresh with another $20,000 allowance in year two. You cannot roll over unused capacity.

When Break Costs Apply and How They Are Calculated

Break costs apply when you repay more than the allowable extra amount, discharge the loan early, or switch to a different product before the fixed term ends. The lender calculates the cost based on the difference between your fixed rate and the wholesale rate the lender can now achieve by reinvesting your repaid funds for the remaining fixed term.

If current wholesale rates are lower than your fixed rate, you will pay a break cost. If current wholesale rates are higher, the break cost may be nil or you may receive a break gain, though most lenders do not refund break gains to borrowers. The exact formula varies by lender, but all use a present value calculation that accounts for the remaining term and the interest rate differential.

In a scenario where someone fixed $600,000 over five years and wants to sell the property after two years, the remaining term is three years. If the lender's wholesale rate for a three-year term has dropped by 1.2 percentage points since the loan was written, the break cost could be in the range of $20,000 to $25,000. If rates have risen, the break cost may be nil. You can request a break cost estimate from your lender at any time during the fixed period.

Split Loan Structures for Buyers Who Want Both Certainty and Access

A split loan divides your borrowing between fixed and variable portions. You nominate the percentage allocated to each at the time of application.

This structure suits buyers in Doncaster who want rate certainty on part of their loan while keeping full offset and redraw access on the remainder. The variable portion typically sits alongside a linked offset account, so any funds in that account reduce the interest charged on the variable balance. The fixed portion provides known repayments and protection against rate rises, but usually comes with limited extra repayment capacity and no offset.

As an example, a household borrowing $700,000 might fix $400,000 over three years and leave $300,000 on a variable rate with full offset. They continue to use the offset account as their main transaction account, depositing salary and building savings there. The fixed portion covers roughly 57 per cent of the loan, which gives meaningful protection if variable rates rise, while the variable portion preserves full flexibility for lump sum repayments, bonuses, or an inheritance without triggering break costs.

Many buyers in the Doncaster area, where median property values sit above the metropolitan average and household incomes often support higher repayment capacity, find the split structure aligns with both their need for budget certainty and their ability to make irregular contributions when cash flow allows.

Can You Refinance a Fixed Rate Loan Before the Term Ends?

You can refinance a fixed rate loan at any point, but if you do so before the fixed term expires, break costs will apply unless wholesale rates have risen above your fixed rate. The new lender does not pay your break costs. You pay them to your existing lender as part of the discharge process.

Refinancing during a fixed term makes financial sense when the interest rate saving with the new lender, calculated over the remaining loan term, exceeds the break cost. Some lenders offer a rebate or cash contribution toward refinance costs, which may offset part of the break cost, but you need to confirm what is covered before proceeding.

If you are within six months of your fixed term expiring, most mortgage brokers will recommend waiting until the term ends rather than refinancing early, unless there is an urgent need to access equity or change loan features. Once the fixed term ends, you can refinance or switch products without any break cost.

What Happens When Your Fixed Rate Expires

When your fixed term ends, your loan automatically reverts to the lender's standard variable rate unless you have arranged to refix or refinance beforehand. The standard variable rate is typically higher than the lender's advertised new customer variable rate.

You should receive a fixed rate expiry notice from your lender around 30 to 90 days before the term ends. This notice will show your current repayment, your new repayment at the standard variable rate, and any options to refix or switch products within the same lender. You are not required to stay with your current lender. This is the most common time to refinance, as there are no break costs and you can access current market rates and features from any lender.

Buyers near Doncaster and surrounding areas including Templestowe, Bulleen and Warrandyte often use the fixed rate expiry as an opportunity to review their entire loan structure, particularly if their circumstances have changed since the original loan was written. For owner-occupiers who have built equity and now want to purchase an investment property, this is also the point at which splitting the loan or establishing separate facilities becomes practical without cost.

Fixed Rates with Offset: Why Most Lenders Do Not Offer It

Most lenders do not offer a linked offset account on fixed rate loans. The reason is structural. A fixed rate loan provides the lender with a known return over a set period, which allows the lender to match that loan against fixed-term wholesale funding. An offset account reduces the interest you pay by offsetting your account balance against the loan balance, which creates a variable return for the lender. The two structures do not align.

A small number of lenders do offer a partial offset on fixed rate loans, typically capped at a percentage of the loan balance or with reduced offset effectiveness. These products usually come with a higher fixed rate compared to a standard fixed loan without offset. Whether the higher rate is worth the offset access depends on how much you expect to hold in the offset account and how long you plan to keep the fixed rate.

For most buyers, a split structure with offset on the variable portion provides better value than paying a rate premium for partial offset on a fixed loan. If maintaining full offset is a priority, keeping a larger variable portion or fixing a smaller percentage makes more sense.

Should You Fix If You Plan to Make Large Extra Repayments?

If you expect to make large or irregular extra repayments, a variable rate loan or a split with a larger variable portion will usually suit you better than a full fixed rate. The annual extra repayment limit on most fixed loans is not high enough to absorb significant lump sums without incurring break costs.

Consider a buyer who has sold an investment property and will receive $150,000 in net proceeds within the next 12 months. If they fix their entire home loan, they will either need to hold that $150,000 outside the loan structure or pay a break cost to apply it. If they keep the loan fully variable with offset, they can deposit the funds into offset immediately and reduce interest from that day without any penalty. Alternatively, a split structure with $200,000 fixed and the remainder variable allows them to apply the lump sum to the variable portion while still securing part of the loan at a fixed rate.

Flexibility has a cost. Variable rates are typically higher than fixed rates in most rate environments. The decision comes down to whether the ability to make extra repayments without restriction is worth the higher rate, or whether the certainty and lower repayment of a fixed rate outweighs the loss of flexibility.
