Top tips to use variable rate loan features

Variable Rate Offset Accounts: How They Reduce Interest Costs

An offset account reduces the interest charged on your loan by offsetting your account balance against the outstanding loan amount. If you hold a $600,000 variable rate loan and maintain $40,000 in a linked offset account, interest is calculated on $560,000 rather than the full loan amount.

Consider a solicitor with variable rate debt of $750,000 at 6.2% per annum. They maintain $65,000 in their offset account, which includes operating funds for their practice and savings set aside for quarterly tax instalments. Over a year, the offset reduces interest charged by approximately $4,030. Rather than earning marginal interest in a savings account and paying tax on that income at their marginal rate, the offset delivers a tax-free reduction in mortgage interest.

The offset operates in real time. Each day, the balance in the offset account reduces the portion of your loan on which interest accrues. For legal professionals with irregular income patterns or retention of client funds in trust, an offset account attached to an owner occupied home loan allows surplus funds to work against debt without losing liquidity. Funds remain accessible at all times without requiring a redraw request or incurring additional fees.

Redraw Facilities: Access to Additional Repayments

A redraw facility allows you to withdraw additional repayments you have made above the minimum required amount. If your required monthly repayment is $4,200 and you consistently pay $5,000, the additional $800 each month accumulates as available redraw. You can access those funds if needed, subject to the lender's terms.

Redraw is not the same as an offset account. Funds in redraw are treated as repayments that reduce your loan balance and the interest charged. Once withdrawn, the loan balance increases again and interest recalculates accordingly. Some lenders impose minimum redraw amounts, processing times or fees. Others allow instant online redraw at no cost. The terms vary between products and should be confirmed before you rely on redraw as a liquidity mechanism.

For lawyers managing variable cash flow, redraw provides a mechanism to reduce debt during high-income months while retaining access to those funds if a gap occurs between billing and receipt. It does not offer the same real-time flexibility as an offset account, but it serves a similar purpose where offset is not available or where the loan structure does not support a linked account.

Making Extra Repayments Without Penalty

Variable rate loans typically allow you to make additional repayments without incurring penalties. This is one of the core differences between variable and fixed rate structures. You can pay more than the scheduled minimum at any time, either as lump sums or through increased regular repayments, without break costs or fees.

Additional repayments reduce the principal balance, which in turn reduces the total interest paid over the life of the loan. Even modest increases to the repayment amount can reduce the loan term substantially. A $700,000 loan at 6.0% over 30 years requires a monthly repayment of approximately $4,196. Increasing that repayment by $500 per month can reduce the loan term by several years and save tens of thousands in interest, depending on how consistently the additional amount is maintained.

For legal professionals whose income increases with seniority or partnership, the ability to increase repayments as income rises is one of the most useful features of a variable rate loan. Unlike a fixed rate product, there is no restriction on the amount or frequency of additional repayments. This flexibility is particularly relevant for barristers and sole practitioners whose fee income can vary significantly between quarters.

Repayment Flexibility: Switching Between Principal and Interest and Interest Only

Some variable rate loans allow you to switch between principal and interest repayments and interest only repayments without refinancing or applying for a new loan. This flexibility is not universal across all products, but where available, it can be a useful tool for managing cash flow during specific periods.

Interest only repayments reduce the monthly obligation by removing the principal component. This can be appropriate during periods of reduced income, such as parental leave, sabbatical, or the establishment phase of a new practice. It can also be used strategically for investment loans, where the borrower prioritises debt reduction on owner-occupied debt or directs surplus cash flow to other investments.

Switching from principal and interest to interest only does not reduce the total loan balance or the total interest paid over the life of the loan. In fact, it extends the loan term and increases total interest unless additional repayments are made during or after the interest only period. The decision to switch should be based on a clear cash flow requirement, not on a desire to minimise repayments for convenience. Some lenders require a formal application and serviceability reassessment before approving a switch to interest only, even on a variable rate loan. Others allow the change to be made through online banking or a single phone call, subject to the terms of the loan contract.

Portability: Taking Your Loan to a New Property

Portability allows you to transfer your existing loan to a new property without discharging the original loan or incurring discharge fees. This feature is particularly relevant when you sell your current home and purchase another within a short time frame, such as in a bridging loan scenario or when upsizing.

A portable loan retains the same loan account number, the same interest rate, and the same terms. If the new property is more expensive than the property being sold, you can typically increase the loan amount to cover the shortfall, subject to serviceability and valuation. If the new property is less expensive, the loan balance reduces accordingly.

Portability avoids discharge fees, application fees, and the administrative burden of applying for a new loan. It can also preserve a discounted interest rate that may no longer be available to new borrowers. However, portability is not available on all variable rate products, and some lenders impose strict conditions, including time limits between settlement of the old property and settlement of the new property. If portability is a feature you are likely to use, confirm the lender's specific terms before committing to the loan.

Split Loan Structures: Combining Variable and Fixed Rates

A split loan divides your total borrowing between a variable rate portion and a fixed rate portion. You can allocate the split in any proportion that suits your risk tolerance and cash flow requirements. A common structure is 50% variable and 50% fixed, but you can split 70/30, 80/20, or any other combination.

The variable portion retains all the features discussed in this article: offset, redraw, extra repayments, and flexibility. The fixed portion provides rate certainty and protection against rate increases, but typically restricts additional repayments and does not allow offset. By combining both, you can hedge against rate movements while retaining access to the features that reduce interest costs and improve liquidity.

For legal professionals with predictable fixed expenses and variable income, a split structure can provide both stability and flexibility. The fixed portion covers the base repayment requirement, while the variable portion allows surplus income to reduce debt through offset or additional repayments. This structure is particularly relevant during periods of rate volatility or when you expect your income to increase but want to protect against the risk of rate rises in the interim. You can find more detail on how split structures are used in the context of home loan refinancing.

Linked Offset Accounts: Multiple Accounts Against One Loan

Some lenders allow multiple offset accounts to be linked to a single variable rate loan. This can include a transaction account, a savings account, and even an account held in the name of a trust or company, depending on the lender's policy and the loan structure.

Multiple linked accounts are useful where you manage funds across different entities or accounts for different purposes. A barrister operating through a service trust might hold operating income in a trust account, personal savings in a joint account, and tax provisions in a separate savings account. If all three accounts are linked to the same home loan, the combined balance offsets the loan and reduces interest accordingly.

Not all lenders offer multiple linked offsets, and those that do may impose limits on the number of accounts or the entities that can hold those accounts. The functionality is typically available through the lender's online banking platform, allowing you to view the combined offset balance and the daily interest calculation in real time. If you require this level of flexibility, confirm the lender's policy during the application process rather than assuming it is available across all variable rate products.
