Beginner's Guide to Variable Rate Home Loans

What Is a Variable Rate Home Loan

A variable rate home loan charges interest that can move up or down during the life of your loan. The rate your lender charges typically follows changes made by the Reserve Bank, but lenders also adjust rates based on their own funding costs and commercial decisions.

Consider a community pharmacist purchasing an apartment near the hospital precinct where they locum. They arrange a variable rate loan at current variable rates and lock in an offset account. Six months later, the Reserve Bank drops rates by 0.25 per cent and their lender passes on 0.20 per cent within a fortnight. Their repayment falls without any application or paperwork. Two years after that, they move into part ownership of the pharmacy and start drawing a different income mix. Because the loan is variable, they can increase repayments or redraw without penalty, and the offset account continues to reduce interest on the outstanding balance.

Variable loans work well when you expect your income or cash position to shift. Pharmacy careers often involve a move from employment to partnership, a change in hours, or a period of contracting income while you complete post-graduate qualifications. A variable structure lets you adjust repayments or access funds as those changes happen, without the cost or delay involved in refinancing.

How Variable Rates Are Calculated and Adjusted

Your lender sets a variable rate based on the cost of funds, regulatory capital requirements, and a margin that covers operating costs and profit. When the Reserve Bank changes the cash rate, most lenders adjust variable rates within days or weeks. The size and timing of the adjustment depends on the institution and the funding model it uses.

Some lenders offer a discount off a published standard variable rate. The discount might be fixed for the life of the loan, or it might be conditional on maintaining a minimum loan balance or keeping other products with the lender. If the discount is conditional, the rate you pay can increase if you no longer meet the criteria, even if the Reserve Bank has not moved.

Lenders also apply risk-based pricing. Two pharmacists applying for the same loan amount might receive different rates based on their deposit size, employment structure, or the property type they are purchasing. A hospital pharmacist with a 25 per cent deposit buying an established house will generally receive a lower rate than a locum pharmacist with a 10 per cent deposit buying an apartment in a high-density development, even if both applicants have similar incomes and credit profiles.

Variable Rate Features That Matter for Pharmacists

Most variable rate loans include an offset account. This is a transaction account linked to your mortgage. The balance in the offset account reduces the amount of interest charged on your home loan each day, without affecting your ability to access the funds. If you hold a buffer for locum gaps, keep practice sale deposits, or accumulate cash while deciding on your next property purchase, an offset account reduces the interest cost of holding those funds.

Variable loans also allow additional repayments without penalty. You can pay more than the minimum each month and reduce the principal faster. Some lenders allow unlimited additional repayments, while others cap the amount you can prepay in a given year. Check the product disclosure before committing.

Redraw facilities let you access any extra repayments you have made above the minimum. If you have paid an additional $30,000 over three years and need funds for a renovation or a deposit on an investment property, you can redraw that amount without refinancing. Redraw is not available on all products, and some lenders charge a fee or require a minimum redraw amount. The redraw balance is not a separate account and is not protected in the same way as funds held in an offset account, so if you anticipate needing regular access to surplus cash, an offset account is usually the more appropriate option.

Portability allows you to transfer your existing loan to a new property without reapplying or paying discharge fees. This can be useful if you move locations for work or upgrade your home. Not all lenders offer portability, and those that do may apply conditions around timing, loan amount, and the new property type. Portability is particularly relevant for pharmacists who move between regional and metropolitan roles or relocate to take up a pharmacy manager or clinical position in a different health district.

Comparing Variable Rates Across Lenders

The advertised variable rate is not always the rate you will receive. Lenders publish a comparison rate that includes the interest rate plus most fees and charges, expressed as a single annual percentage. The comparison rate is calculated on a loan amount of $150,000 over 25 years and is designed to help you compare the total cost of different loan products. It does not account for offsets, redraws, or any features that reduce the interest you actually pay, so it is a starting point rather than a complete picture.

Some lenders offer a lower headline rate but charge higher ongoing fees or restrict access to features like offset accounts and unlimited additional repayments. A loan with a slightly higher interest rate and a full offset account often costs less over time than a loan with a lower rate and no offset, particularly if you hold significant savings or irregular income.

Rate discounts are often negotiable at the time of application, and again when you refinance your home loan. If you have built equity, maintained consistent repayments, or increased your income since you first borrowed, you may be able to negotiate a larger discount. Pharmacists who have moved from graduate roles to senior clinical or managerial positions, or who have taken on partnership equity, are often in a stronger position to negotiate than they were when they first purchased.

Variable vs Fixed: When Each Structure Fits

A variable rate suits borrowers who value flexibility and want to reduce interest costs when they have surplus cash. A fixed rate locks in your repayment for a set period, usually one to five years, and protects you from rate increases during that time. Fixed loans typically restrict additional repayments to a maximum of $10,000 to $30,000 per year, do not include offset accounts, and charge break fees if you repay early or refinance before the fixed term ends.

Some pharmacists use a split loan structure, where part of the loan is fixed and part is variable. This gives you certainty on a portion of your repayment while maintaining flexibility on the rest. A split structure works well if you want to limit your exposure to rate rises but still need access to an offset account or the ability to make large additional repayments without penalty.

The choice between variable, fixed, and split depends on your income structure, how much cash you hold outside the loan, and whether you expect to sell, refinance, or significantly increase repayments in the next few years. If you are in the early stage of your career with limited savings and a stable salary, a fixed rate might provide certainty. If you have irregular income, access to a family trust, or expect a significant cash injection from a property sale or inheritance, a variable rate with a full offset is usually more appropriate.

Rate Movements and Timing

Variable rates can move up or down multiple times in a single year. Between early 2022 and late 2023, the Reserve Bank increased the cash rate 13 times in 18 months, and most lenders passed on the full amount of each increase. Borrowers who had fixed their loans in 2020 and 2021 at rates below 2 per cent were protected until their fixed term ended, at which point they moved to variable rates that had increased by more than 4 percentage points.

You cannot predict rate movements with certainty, and attempting to time the market often results in a worse outcome than choosing the structure that aligns with your financial position and near-term plans. If you are deciding between variable and fixed, focus on whether you need flexibility or certainty, not on where you think rates will be in 12 months.

Switching From Variable to Fixed, or Vice Versa

Most lenders allow you to switch from a variable rate to a fixed rate, or from fixed to variable, during the life of your loan. Switching from variable to fixed usually incurs no cost, though the fixed rate you receive will be the current market rate at the time of the switch, not the rate you were paying on your variable loan. Switching from fixed to variable before the fixed term ends will incur break costs, which can be substantial if rates have fallen since you fixed.

If you are approaching the end of a fixed term and want to refix, you can usually lock in a new rate up to 90 days before the existing fixed term expires. If you do nothing, your loan will automatically revert to the lender's standard variable rate, which is typically higher than the discounted variable rate available to new borrowers. You should review your options at least three months before your fixed term ends and either negotiate a new rate with your existing lender or refinance to a different lender if a better offer is available.
