Variable Rate Loans and Extra Repayments: What to Know

Variable rate loans give you flexibility that fixed loans don't, and one of the most useful features is the ability to make extra repayments without penalty.

If you're buying a property around Toowong, where the mix of apartments near the station and post-war homes closer to the river attracts both first-time buyers and investors, understanding how extra repayments work can make a real difference over the life of your loan. Making additional payments reduces the principal faster, which means you pay less interest overall and build equity sooner. The decision you're facing is whether a variable rate loan suits your situation, and if so, how to use the repayment flexibility to your advantage.

How Extra Repayments Reduce Your Loan Term and Interest

When you make an extra repayment, the additional amount goes straight to the principal, not the interest. This reduces the balance you're charged interest on in the following period, which compounds over time. Even small additional amounts can have a meaningful impact if you maintain them consistently.

Consider a buyer who purchases an apartment in Toowong and takes out a variable rate loan. They decide to pay an extra $200 per fortnight above the minimum repayment. That $200 chips away at the principal each time, which means the lender calculates interest on a slightly smaller balance every fortnight. Over several years, this approach shortens the loan term and reduces the total interest paid. The outcome depends on the loan amount and the rate, but the principle remains the same: less principal means less interest.

Variable Rate Loans and Offset Accounts

Most variable rate products come with the option to link an offset account, which works alongside extra repayments to reduce interest further. An offset account is a transaction account where the balance is subtracted from your loan balance when the lender calculates interest.

If you're holding savings for upcoming costs like rates, insurance, or maintenance, parking that money in an offset account rather than a separate savings account means you're reducing the interest charged on your home loan every day. The funds remain accessible, so you don't lose liquidity, but you also don't pay interest on the portion of your loan that's offset by the account balance. This feature is particularly useful for buyers in Toowong who might keep a buffer for strata fees or body corporate levies on apartments, or for those managing rental income and expenses on an investment property.

Redraw Facilities and How They Work

Most variable rate loans include a redraw facility, which allows you to access extra repayments you've made if you need them later. This is different from an offset account. With a redraw, the extra money you've paid is no longer sitting in a separate account—it's been applied to the loan principal. You can usually request to withdraw it, but conditions vary between lenders.

Some lenders allow unlimited free redraws through online banking. Others charge a fee per redraw or limit the number of redraws you can make in a year. If you're planning to make extra repayments but want the option to access those funds in an emergency, check the redraw terms before you commit to a product. In our experience, buyers who value flexibility tend to prefer offset accounts over redraw facilities, because the money stays liquid and there's no need to request access.

What Happens If You Switch to a Fixed Rate Later

If you start with a variable rate loan and later decide to fix your rate, the extra repayments you've already made remain applied to the principal. However, once you're on a fixed rate, most lenders either restrict or prohibit extra repayments beyond a certain annual limit, often around $10,000 to $30,000 depending on the lender. If you exceed that limit, you may be charged a fee or face break costs.

This is one reason some borrowers opt for a split loan structure, where part of the loan is fixed and part remains variable. The variable portion still allows extra repayments and retains the offset account, while the fixed portion provides rate certainty. If you're weighing up whether to fix part of your loan, our fixed rate expiry page covers the considerations involved when moving between rate types.

Loan to Value Ratio and Extra Repayments

Making extra repayments also improves your loan to value ratio (LVR), which is the percentage of the property value that you've borrowed. A lower LVR can reduce the interest rate you're offered when you refinance, and it may allow you to remove Lenders Mortgage Insurance (LMI) if your LVR drops below 80%.

In a scenario like this: a borrower in Toowong buys a townhouse and takes out a loan with an LVR of 85%, which requires LMI. Over three years, they make consistent extra repayments and the property value increases modestly. Their LVR drops to 78%. When they refinance, they're no longer required to pay LMI, and they're offered a lower rate because their equity position is stronger. The extra repayments didn't just reduce interest—they also improved their refinancing options.

Variable Rates and Rate Discounts

Variable rate loans often come with rate discounts based on factors like your LVR, loan amount, and whether you have an offset account or professional package. These discounts can change over time, and some lenders adjust them without notice. If you've been in your loan for a few years and haven't reviewed your rate, there's a chance you're no longer receiving the same discount that new customers are offered.

This is where a loan health check becomes useful. We compare your current rate and features against what's available across the market, and if there's a better option, we help you move across. For Toowong buyers who purchased a few years ago and have been making extra repayments, refinancing to a lower rate can amplify the impact of those additional payments.

When Extra Repayments Don't Make Sense

There are situations where making extra repayments isn't the priority. If you're carrying higher-interest debt like credit cards or personal loans, paying those down first usually makes more financial sense. Similarly, if you're planning a renovation or expecting a significant expense in the near term, keeping cash on hand rather than locking it into your home loan might be the more practical approach.

For investors, the calculation is different again. If your property is negatively geared and you're claiming the interest as a tax deduction, reducing the loan balance through extra repayments also reduces your deduction. In that case, holding surplus funds in an offset account instead of making extra repayments gives you the interest saving without reducing the deductible loan balance.
