Variable Rate Home Loan: Pros and Cons Explained for Homebuyers

Not sure which type of home loan is right for you? One of the biggest decisions when buying property is choosing between a variable-rate home loan and a fixed-rate loan.

In Australia, variable home loans are the go-to option for many borrowers. They offer flexibility, potential savings, and a range of features, but they also come with some financial risks.

This guide breaks down exactly how variable-rate home loans work, their pros and cons, and what to consider before signing on the dotted line.

Kelly Brothers Finance helps you take advantage of variable home loan features, from offset accounts to redraw, without the confusion. Talk to your local Brisbane mortgage brokers today at (07) 3847 9450 or visit us at www.kellybrothersfinance.com.au.

What Is a Variable Rate Home Loan?

A variable-rate home loan is a type of home loan where the interest rate can go up or down at any time during the loan term. It’s not locked in like a fixed-rate loan. 

Instead, it moves with changes in the economy, mainly influenced by the official cash rate set by the Reserve Bank of Australia (RBA), along with lender decisions. This means your loan repayments might be lower one month and higher the next, depending on how the market conditions shift. 

How It Differs from Fixed-Rate Loans

A fixed-rate loan locks in your interest rate for a set period of time, often between 1 to 5 years. Your repayments stay the same during that period, giving you certainty.

A variable loan does the opposite. The loan interest rate can change at any time. This affects your repayment amounts, which means they could rise or fall. So:

• Fixed = stability and predictability
  
  
• Variable = flexibility and potential savings (or extra costs)
  
  

With a variable loan, you can usually make extra repayments without fees, access offset accounts, and redraw funds you’ve already paid. Fixed loans often don’t allow this.

How Interest Is Adjusted by Lenders

Your variable interest rate can change due to several reasons:

• If the RBA changes the official cash rate, your lender might pass this change on.
  
  
• Lenders also look at their own borrowing costs and market factors.
  
  
• Some lenders act quickly when rates move; others take their time.
  
  
• Changes aren’t always announced well in advance—you might just get a notice that your rate is going up next month.

This is why many borrowers on variable rates keep a close eye on economic updates and lender notices.

Common Terms and Loan Features

Most variable home loans come with a range of handy features. Here’s what you’ll typically get:

• Offset accounts – These reduce the interest you pay by linking your loan to a transaction account. The more money sitting in the offset, the less interest you’re charged on your loan balance.
  
  
• Redraw facility – If you’ve paid more than the minimum repayment, you can access that money again.
  
  
• Additional repayments – You can make extra payments at any time, helping to shorten your loan term and save on interest.
  
  
• Flexible repayment types – Choose between weekly, fortnightly, or monthly repayments to suit your cash flow.
  
  
• Split loan option – You can split your loan into fixed and variable portions to balance out risk and flexibility.
  
  
• Optional features – Some loans come bundled with discounts on credit cards, fee waivers, and package deals.

Keep in mind that loan fees, like application fees, monthly maintenance fees, and settlement costs, can vary between lenders. Always read the fine print in the loan contract.

Simple Scenario: How It Works

Let’s say Jake, a first-time buyer in Brisbane, takes out a $600,000 variable rate loan with an interest rate of 6.65% p.a.

• His starting monthly repayment is around $3,860.
  
  
• Jake parks $20,000 in his offset account, reducing the interest payable on his loan to the equivalent of $580,000.
  
  
• A few months later, the RBA cuts the cash rate. His lender lowers his rate to 6.30%, and now his repayment drops to about $3,700.
  
  
• If the rate goes up again to 7.00%, his repayment could rise to around $4,000.

Because Jake also makes extra repayments and uses the redraw facility when needed, he has control over his loan. But he still needs to stay alert; rate hikes can happen fast and without much warning.

Pros and Cons of Variable Rate Home Loan

Not every home loan suits every borrower, and variable-rate loans are no exception. Depending on your financial circumstances, goals, and risk appetite, this option might offer freedom or come with a few unexpected bumps.

Here are the real-world pros and cons of a variable-rate home loan, especially for Australians navigating today’s lending market.

Pros of a Variable Rate Home Loan

1. Flexible Additional Payments

You can usually make additional payments on your loan at any time without penalty. This gives you more control to reduce interest over time and shorten your loan term, an easy win if your income allows it.

2. Potential for Cost Savings

When the RBA lowers the official cash rate, many lenders pass on those savings by reducing their loan rates. That could translate into real cost savings over the life of your loan.

3. Fewer Break Costs

Unlike fixed-rate loans, variable-rate loans usually don’t come with break costs or break fees. This gives you the flexibility to refinance, sell, or switch loan products without hefty penalties.

4. Easier Conditional Approval

Getting conditional approval is often quicker with a variable home loan, especially if you meet lending criteria and complete a clean credit check. Lenders may be more open to a range of loan amounts when interest rates aren’t locked.

5. Loan Features and Flexibility

Most variable loans come with features like offset accounts, redraw facilities, and flexible repayment types. They also tend to have fewer restrictions when it comes to repayment fees or switching your rate term later.

6. Suits a Range of Financial Circumstances

Variable loans are ideal for borrowers with fluctuating incomes or those planning to make lump sum payments. It’s also great for those who anticipate moving or refinancing before the end of a typical rate period.

7. Broad Eligibility and Loan Options

Many lenders offer a wide range of eligible home loan products with variable rates, covering everything from first-home buyers to investment loans, construction loans, and refinancing options.

Cons of a Variable Rate Home Loan

1. No Predictability in Rate Term

Because your loan rates change based on external market conditions, there’s no certainty during the rate period. This unpredictability can make budgeting harder, especially if you're planning long-term financial commitments.

2. Exposure to Rate Rises

If the RBA increases the cash rate, your lender may pass that increase on, causing your monthly repayments to rise. For borrowers without a financial buffer, this can create pressure over time.

3. No Cap on Repayment Changes

Unlike capped-rate or fixed loans, there’s no upper limit to how high your repayment amounts can go. This is especially challenging if your income isn’t flexible or you have other debts.

4. Not Ideal for Long-Term Planning

For borrowers aiming for a long rate term or who rely on strict budgeting, the ups and downs of variable rates can add stress. If you're unsure about your job stability or income, this might not be ideal.

5. Higher Comparison Rate May Apply

Variable loans often advertise lower initial rates, which can seem appealing at first. However, the comparison rate, which includes fees and average costs, can be higher than fixed-rate loans, especially with application or monthly service fees added in.

6. Can Affect Borrowing Power

A variable loan might not offer the same maximum loan term or minimum loan flexibility as other loan types when assessed by lenders. Depending on their credit criteria, your total borrowing power might be lower.

7. Upfront Costs Still Apply

You’ll still need to pay standard buying costs like stamp duty, property valuation, and other upfront fees, regardless of whether your loan is fixed or variable. Some borrowers assume variable loans skip these, but that’s not the case.

So while variable-rate loans offer flexibility, potential cost savings, and room for additional payments, they also come with market-driven risk and less certainty about future repayment amounts. 

Knowing the full picture, both benefits and trade-offs, is key before making the call.

Frequently Asked Questions (FAQs)

Is it a good idea to get a variable-rate mortgage?

It’s a solid choice if you want flexible payments, an offset facility, and the freedom to make extra repayments. A variable home loan interest suits borrowers comfortable with changing monthly payments, especially if planning to refinance or sell within a shorter span of a typical 25-year term. 

Just watch for payment fee changes and ongoing home loan fees, and always check with a loan expert to match the loan to your goals.

What is the current rate for a variable mortgage?

As of mid-2025, the current interest rate for a variable home loan in Australia is around 6.72% p.a. Rates vary by lender, loan type, and whether you're an owner occupier or buying for investment purposes. They can also shift quickly with RBA moves or economic changes.

Is 3.5% a good interest rate?

A 3.5% variable rate was great a few years ago, but in 2025 it’s well below today’s average of 6.5%–7%. If you’re offered that on a secured loan or split home loan with solid terms, it’s worth a serious look. Just act fast if it’s legit.

Will interest rates go down in 2025 in Australia?

Forecasts are mixed. The RBA has held steady so far, but there’s hope of easing later in the year. If inflation continues to cool, we may see reductions in the variable home loan interest rate. Still, there’s no guarantee. A split home loan can help manage risk while offering the benefits of a variable portion.

What is the biggest downside to variable-rate loans?

The biggest downside is unpredictability. Variable rate changes can spike monthly payments, and features vary by lender. You might face fees like annual package or payment charges, making it less ideal if you need stability.
