Fixed Rate Loans & Extra Repayments: What Works

Most fixed rate products allow some level of extra repayment each year, typically between $10,000 and $30,000 depending on the lender and the rate you locked in.

The limit matters when you receive a substantial bonus, distribute partnership profits, or settle a property and want to deploy capital toward reducing debt. If you plan to make regular additional payments beyond what the lender permits, a fixed rate loan will restrict that capacity and may trigger break costs if you exceed the threshold. The alternative is structuring part of the loan as variable rate or considering a split loan that gives you flexibility on one portion while locking certainty on another.

Why Lenders Cap Extra Repayments on Fixed Rates

Lenders fund fixed rate loans by locking in wholesale funding costs for the term of the loan. When you repay principal early, the lender loses the margin they expected to earn on that principal for the remainder of the fixed period. The cap limits their exposure to that risk. The annual limit is not a regulatory requirement but a product feature set by each lender based on their funding model and risk appetite. Some lenders offer higher caps, others lower, and a handful allow unlimited additional repayments without penalty, though those products typically carry a higher fixed interest rate to compensate for the additional risk.

Consider a solicitor who locks in a three-year fixed rate on a $600,000 loan with a $20,000 annual extra repayment cap. In the first year, they contribute $15,000 in additional principal from retained earnings. In the second year, they receive a $50,000 distribution and want to apply $40,000 to the loan. The lender will accept $20,000 without issue. The remaining $20,000 either triggers a break cost calculation or needs to be redirected to an offset account if the loan structure includes one, or held in a separate savings account until the fixed term expires.

How Extra Repayments Affect Loan to Value Ratio

Every dollar of extra principal repayment reduces your outstanding loan balance and improves your loan to value ratio. That ratio directly affects your borrowing capacity when you apply for additional lending, whether for an investment property, a larger principal place of residence, or a construction project. Lenders reassess your LVR at the time of each new application, not just at settlement of the original loan. A lower LVR can also position you to remove LMI on a future refinance or eliminate it entirely if you started with a loan above 80 per cent and have since reduced the balance below that threshold through extra repayments and property value appreciation.

In a scenario where a solicitor purchases at an LVR of 85 per cent and makes $25,000 in extra repayments over two years while the property appreciates modestly, the LVR might fall to 78 per cent by the time they apply for a second property loan. That shift changes the risk weighting applied under APS 112 and can reduce the interest rate offered on the new loan, as well as the amount of equity available to use as security.

Split Loan Structures for Repayment Flexibility

A split loan divides your total borrowing into two or more portions, each with its own interest rate structure. One common approach is fixing 50 to 70 per cent of the loan to lock in repayment certainty, while leaving the remainder on a variable rate with an offset account and unlimited extra repayments. This structure lets you direct surplus income or windfalls to the variable portion without restriction, while the fixed portion provides protection against rate rises on the majority of your debt.

The proportion you fix depends on your cash flow predictability, your tolerance for rate movement, and how much surplus income you expect to generate. Solicitors in their first few years of practice might fix a higher proportion because cash flow is less predictable and the priority is repayment stability. Those with established practices, regular distributions, or dual professional incomes might fix a smaller proportion to retain flexibility for accelerated repayments.

Split structures also allow you to stagger fixed rate expiry dates. If you fix two portions for different terms, say two years on one and four years on the other, you avoid the situation where your entire loan reverts to a variable rate on the same day. Staggered expiry gives you the option to refinance one portion while leaving the other untouched, or to renegotiate terms incrementally rather than in a single high-stakes conversation with your lender at a moment when rates might not be in your favour.

Break Costs and How They Are Calculated

If you repay more than the allowed limit during a fixed rate period, or if you refinance or sell the property before the fixed term ends, the lender may charge a break cost. The cost is calculated based on the difference between the fixed rate you are paying and the rate the lender can now earn by reinvesting the funds you are repaying early, multiplied by the outstanding loan balance and the remaining term.

Break costs are not a penalty in the conventional sense. They are a reimbursement to the lender for the economic loss they incur when their funding position changes unexpectedly. If variable rates have fallen since you fixed, the break cost will be higher because the lender can only reinvest your repaid principal at a lower rate than the one you locked in. If variable rates have risen, the break cost may be zero or close to it, because the lender can reinvest at a higher rate.

As an example, if you fixed at 5.5 per cent three years ago and variable rates are now 4.8 per cent, breaking the loan with two years remaining might generate a cost of several thousand dollars on a $500,000 balance. If rates have risen to 6.2 per cent, the break cost would likely be nil. Lenders are required to provide a break cost estimate on request, and that estimate should be obtained before making any decision to refinance or repay a fixed loan early.

Offset Accounts on Fixed Rate Loans

Most fixed rate products do not include an offset account. The few that do typically offer a partial offset, such as 40 or 60 per cent of the balance in the offset account, rather than the full 100 per cent offset available on most variable rate loans. A partial offset reduces the interest charged, but not by the full amount you might expect.

If your priority is to park surplus cash and reduce interest without formally repaying principal, a variable rate loan with a full offset account will deliver a larger saving. If your priority is rate certainty and you are willing to forgo offset functionality, a standard fixed rate product will usually offer a lower headline rate than a fixed rate loan with an offset feature.

For solicitors who expect to hold significant cash balances for trust account shortfalls, tax provisions, or partnership capital calls, the offset account can be more valuable than a lower fixed rate, even if the offset is only partial. The decision depends on how much cash you expect to hold and for how long.

Portable Loans and Relocation Scenarios

A portable loan allows you to transfer your existing fixed rate to a new property if you sell your current home and purchase another during the fixed term. Portability avoids break costs and allows you to retain the fixed rate you originally locked in, which can be valuable if rates have since risen.

Not all lenders offer portability, and those that do impose conditions. The new property must be owner-occupied, the loan amount must remain the same or increase, and the transfer must occur within a short window, typically 30 to 90 days. If you are relocating for a new role, moving from one practice to another, or upsizing to a larger home, portability can preserve both your fixed rate and your repayment structure without triggering a full refinance.

If portability is a consideration, confirm the feature is included in your loan contract before settlement. It is not a standard feature across all fixed rate products, and it cannot be added retrospectively.
