Switch from variable to fixed: what you need to know

Your interest rate affects every repayment you make for years to come.

If you're on a variable rate and watching your repayments shift each month, or if your fixed rate period is ending soon, you might be thinking about switching. The decision isn't just about whether rates might rise or fall. It's about what works for your budget, how long you plan to stay in the property, and what you'd do if your circumstances changed.

Why people refinance from variable to fixed rate

Refinancing to a fixed rate means your repayments stay the same for a set period, typically between one and five years. You're trading flexibility for certainty. If you're managing a tight budget or you know you'll need consistent repayments for the next few years, that certainty can be worth it.

Consider someone with a $450,000 home loan in Glenorchy who's been on a variable rate for two years. Their repayments have shifted three times in the past twelve months. They've just had a second child and one partner is dropping to part-time work. With less income and tighter cashflow, they want to know exactly what their mortgage costs each fortnight. A fixed rate gives them that predictability while they adjust to a single income.

That doesn't mean fixed rates suit everyone. If you're planning to sell within two years, or if you regularly make extra repayments above the minimum, locking in might cost you more than it saves. Most fixed rate products cap additional repayments at around $10,000 to $20,000 per year. Go beyond that and you could face penalties.

What happens when your fixed rate period ends

Most lenders will move you to their standard variable rate when your fixed term expires. This is usually higher than the discounted variable rates offered to new customers. In some cases, that jump can add $200 or more to your monthly repayment.

If your fixed rate is ending in the next three to six months, now is the time to review your options. You can refinance to a new fixed rate, switch to a variable rate, or negotiate a lower rate with your current lender. Don't wait until the expiry date. Lenders need time to assess your application and organise valuations, and leaving it too late could mean you're stuck on a higher rate for months.

As an example, someone with a $380,000 mortgage in Rokeby locked in a fixed rate three years ago at a rate that was attractive at the time. That term is now ending, and their lender's standard variable rate is higher than what other lenders are offering to new customers. By applying to refinance their home loan two months before expiry, they can compare offers, choose a product that suits their current situation, and avoid the automatic rollover to a less favourable rate.

How the refinance application works

The refinance process involves a new loan application, even if you're staying with the same lender. The lender will assess your income, expenses, credit history, and the current value of your property. They'll also want to know your loan amount and how much equity you have.

If your property has increased in value since you first bought it, you might have more equity than you realise. That can improve your borrowing position and may give you access to lower rates. If the value has dropped or stayed flat, or if your financial situation has changed, it's worth discussing those details early so there are no surprises.

For properties in Tasmania, particularly in areas like Moonah or Kingston where the market has seen steady demand, a property valuation as part of the refinance process often reflects gains that weren't there a few years ago. That equity can work in your favour when negotiating terms.

Most lenders will also assess whether the new loan reduces your overall loan costs or improves your financial position. If you're consolidating other debts or releasing equity for another purpose, they'll factor that into the approval.

Fixed or variable: which rate suits your situation

There's no universal answer. It depends on how you use your mortgage and what you need from it.

If you value certainty and you're not planning to make large lump sum repayments, a fixed rate might suit you. If you want the freedom to pay down your loan faster, access a redraw facility, or take advantage of rate cuts, a variable rate offers more flexibility. Some people split their loan, fixing part of it for stability and keeping the rest variable for flexibility.

Whatever you choose, the rate itself is only part of the picture. Look at the features that come with the loan. Does it offer an offset account? Can you make extra repayments without penalty? Are there ongoing fees? Those details affect how much the loan actually costs you and how well it fits your life.

If you're coming off a fixed rate and you're not sure which direction to take, a loan health check can show you where you stand and what options are available. The right choice is the one that matches your budget, your plans, and the way you manage money.

One insight that's often missed

Most people focus on the interest rate when they refinance, but the real cost of switching depends on break costs if you're leaving a fixed rate early, application fees, and any changes to your loan features. If you're currently on a variable rate and switching to fixed, those costs are usually lower. But if you're exiting a fixed term before it ends, the break cost can be significant, sometimes running into thousands of dollars depending on how much time is left and how rates have moved since you locked in.

Before you commit to a refinance, ask your current lender for a discharge statement that includes any break costs or exit fees. Then compare that figure against what you'll save with the new loan. Sometimes the savings don't justify the switch. Other times, even with the upfront cost, you'll come out ahead within the first year.
