Fixed? Variable?... or Have We Been Asking the Wrong Question?

Buying a home is one of life’s biggest milestones. After weeks of inspections, negotiations and paperwork, you’ve finally found the right place; the offer has been accepted, settlement is approaching, and for the first time the excitement of owning your own home starts to feel very real. Then your broker asks a question that seems simple enough: “So… have you thought about whether you’d like a fixed or variable home loan?”

At first glance it sounds like a straightforward decision. Most people assume there are only two choices: lock in the certainty of a fixed interest rate or keep everything variable so you have maximum flexibility. Like many financial decisions, however, what appears simple on the surface is often far more nuanced once you start looking underneath.

Over the years, I've had this conversation hundreds of times, and I've noticed something interesting. The clients who make the best long-term decisions rarely begin by asking whether fixed or variable is "better". Instead, they spend a little time thinking about how they actually manage their money, what gives them confidence, and what they need their home loan to do over the next few years.

That's why I believe most borrowers start in the wrong place, the question isn't really whether you should choose a fixed or variable interest rate. The better question is this:

"How much certainty do I need, and how much flexibility will I genuinely use?"

It's a subtle difference, but it completely changes the conversation. Rather than trying to predict where interest rates are heading, you're designing a home loan around something far more predictable, your own lifestyle.

By the end of this guide, I hope you'll have a much clearer understanding of not only the difference between fixed and variable loans, but also why a growing number of Australians are choosing a third option that often receives far less attention than it deserves.

Everyone Wants to Pick the Winner

If we're honest with ourselves, most of us aren't really choosing between fixed and variable loans, we're trying to predict the future. If we think interest rates are about to rise, we want to lock in a fixed rate before they do. If we believe they're about to fall, the last thing we want is to spend the next few years paying more than we have to. It's completely understandable. Nobody enjoys looking back twelve months later wishing they'd made a different decision.

The difficulty is that predicting interest rates is incredibly hard. Economists disagree with each other, the major banks regularly revise their forecasts, and even the Reserve Bank adjusts its outlook as new information becomes available. There are simply too many moving parts for anyone to consistently know what comes next.

That doesn't mean choosing between fixed and variable is a gamble, it just means I don't think your entire home loan should be built around a prediction that nobody can make with certainty.

Instead, I encourage clients to focus on something we actually do know. We know how stable their income is, whether they already have healthy savings or live pay cheque to pay cheque, and whether they’re planning to start a family, renovate, invest or simply enjoy the security of knowing exactly what their repayments will be each month. Those things are far more predictable than the next interest rate announcement, and in my experience they have a much bigger influence on whether someone ends up happy with their loan.

Once you start thinking about your mortgage that way, the conversation naturally changes. Instead of asking which interest rate is likely to "win", you begin asking which loan structure is most likely to help you achieve your own financial goals.

Understanding Fixed Rate Home Loans

Let's imagine two different borrowers.

The first has just bought their very first home. They have stretched themselves a little to get into the market, they're learning what it's really like to own a property, and every fortnight matters. The mortgage is manageable, but there's not a lot of room for unexpected increases in household expenses. If interest rates were to rise several times over the next year, it would certainly be noticed. The second borrower earns a similar income, but they're much further along in their financial journey. They've built a healthy savings buffer, have plenty of breathing room in their budget and wouldn't lose any sleep if repayments changed a little from one month to the next. Both borrowers might qualify for exactly the same home loan, yet the "right" choice for each of them could be completely different.

That's why I always encourage clients to think about what a fixed rate loan is actually designed to achieve. Contrary to what many people believe, fixing your home loan isn't really about trying to beat the market, it's about buying certainty. When you fix your interest rate, you're locking in your repayments for an agreed period, usually somewhere between one and five years. Regardless of what happens to interest rates during that time, your repayments remain the same. For households working to a carefully planned budget, that consistency can remove a tremendous amount of financial stress.

Think about it this way. If you knew your electricity bill, your insurance premium and your grocery shopping would all remain exactly the same for the next three years, budgeting would become a whole lot easier. A fixed home loan works in much the same way. It removes one of the biggest unknowns from your monthly finances and replaces it with certainty. Of course, certainty has traditionally come at a cost, for many years, fixed rate home loans were considerably less flexible than variable loans. If you wanted to make large additional repayments, keep all of your savings in an offset account or restructure your loan, you often had very limited options. That history is one of the reasons many borrowers still dismiss fixed loans without giving them much thought.

The reality today is quite different, the lending market has become far more competitive over the past decade, and many lenders have responded by introducing features that simply didn't exist on fixed loans years ago. Depending on the lender and the product you choose, you may be able to make additional repayments each year, access a partial offset account or, in some cases, even a full offset account while your loan remains fixed. That's why I always caution clients against making assumptions based on something they heard from a friend or read online several years ago. Two lenders might advertise exactly the same fixed interest rate, yet the flexibility built into those products could be completely different. Looking only at the headline rate is a little like buying a new car based solely on the fuel economy without ever looking at the safety features, the comfort or the warranty.

None of this means fixed loans are automatically the better option. There are still important considerations, including potential break costs if you repay the loan early or refinance before the fixed period expires. My point is simply that the conversation has become much more sophisticated than it used to be. Today, the question isn't whether fixed loans are flexible or inflexible, the better question is whether they offer enough flexibility for the way you actually manage your money, because they're two very different things.

If you rarely make additional repayments, don't expect to accumulate significant savings in an offset account and value the confidence of knowing exactly what your repayments will be, a fixed loan may provide everything you need. On the other hand, if your financial habits revolve around constantly reducing your mortgage balance, then flexibility starts becoming much more important. Which naturally brings us to the other side of the conversation.

Understanding Variable Rate Home Loans

While certainty gives some borrowers confidence, others take comfort from having options. Imagine someone who has owned their home for a few years, settled into a comfortable routine and developed the habit of putting a little extra towards the mortgage whenever they can. If they receive a tax refund it goes straight onto the loan, if work pays a bonus most of that disappears into their offset account, and even an extra fifty dollars at the end of the fortnight feels like another small step towards becoming debt free.

For borrowers like this, flexibility isn't just a nice feature. It's part of the way they manage their money, that's where a variable rate home loan often shines. Unlike a fixed loan, a variable loan isn't locked into one interest rate for a set period. As interest rates move, your home loan generally moves with them, if rates increase, your repayments are likely to rise. If rates fall, your repayments may reduce as well. That uncertainty can make some people uncomfortable, particularly if their household budget is already stretched. But despite that, variable loans continue to be one of the most popular choices for Australian borrowers, and I don't think that's simply because people are trying to guess where interest rates are heading. The real attraction lies in the flexibility they offer, many variable home loans allow unlimited additional repayments, provide access to a full offset account and include redraw facilities if you ever need to access funds you've already paid into the loan. Those features can have a meaningful impact over the life of a mortgage, particularly for borrowers who are disciplined with their savings.

I've had many clients tell me that one of the most satisfying moments each month is watching their offset account slowly grow or seeing the interest charged on their loan gradually reduce because they've been making consistent extra repayments. Those aren't just nice feelings. Over twenty years, habits like that can save thousands of dollars in interest and help people become debt free sooner.

Of course, flexibility comes with its own trade-offs, if interest rates rise, a variable loan doesn't shield you from those increases. Your repayments can change, sometimes several times over the course of a year. For households already operating close to their financial limits, that uncertainty can create genuine pressure, which is why there isn't a single loan type that's right for everybody.

What I've found interesting over the years, though, is that many borrowers have already convinced themselves they need a variable loan long before we sit down together, the conversation usually sounds something like this.

"I definitely want a variable loan because I want to pay my mortgage off faster."

It's a perfectly reasonable answer, in fact, it's one of the most common reasons people choose a variable loan, and in many cases it's absolutely the right decision. But before we lock in that approach, I always ask one more question, not because I think they're wrong, but because I want to make sure we're choosing a loan structure that matches the way they really use their money, rather than the way they hope they'll use it.

That question often changes the entire conversation.

The Question Almost Nobody Asks

By this point, most people expect me to have an opinion. Some assume I’m going to recommend fixing their loan because they like certainty, while others think I’ll encourage them to stay variable because they want to make extra repayments or keep an offset account. Quite often they’re waiting for me to tell them which option is “best,” but instead I ask a question that usually catches them completely off guard: “Do you actually need your entire home loan to be flexible?”

For a moment, the conversation almost stops. It's not because it's a difficult question. It's because it's one that very few borrowers have ever been asked before. Most people have spent their time trying to choose between fixed and variable, without ever stopping to think about whether every dollar of their mortgage needs to behave in exactly the same way.

Let’s imagine you’re borrowing $700,000 and you’ve told me you want a variable loan because you’d like the freedom to make additional repayments whenever you can. Maybe you’ve set yourself a goal of putting an extra $200 a week onto the mortgage, or perhaps you’d like to build up an offset account over time; they’re both sensible goals, and if you can stick to them, they’ll almost certainly reduce the amount of interest you pay over the life of the loan. But if your realistic goal is to contribute an extra $10,000 each year, does every dollar of that $700,000 mortgage actually need to remain variable, or are you choosing flexibility across the entire loan simply because that’s the way people have always talked about home loans?

It’s an interesting question, because once you ask it the decision suddenly becomes much less black and white. Perhaps only part of your mortgage really needs the flexibility that a variable loan provides, while the rest could be working towards a completely different goal, like giving you the confidence of knowing your repayments won’t change over the next few years. When clients start looking at their mortgage this way, you can almost see the lightbulb switch on, they’re no longer trying to choose between two competing products, they’re starting to think about what they actually need their home loan to do, and that’s a very different conversation.

A Home Loan Doesn't Have to Do Just One Job

One of the biggest misconceptions in the mortgage industry is that your home loan has to be either fixed or variable, as though the entire debt needs to be treated exactly the same. I’ve never really understood that way of thinking, because in almost every other part of your financial life you’re probably already doing different things with different money. You might keep some savings in a high-interest account because it’s your emergency fund, invest some money for the long term, and use another account for everyday spending; each pool of money has a different purpose, so why should a $700,000 mortgage only be allowed to have one?

This is where split loans begin to make a lot of sense, rather than asking one loan account to provide certainty, flexibility, offset benefits and unlimited additional repayments all at once, a split loan allows each portion of the mortgage to perform a different role.

Imagine, for example, that same $700,000 loan, instead of keeping the entire balance variable, you might decide to fix $500,000 because that provides confidence that the majority of your repayments won't change. The remaining $200,000 could stay variable, giving you access to an offset account, unlimited additional repayments and the flexibility to adapt as your circumstances change, nothing has been sacrificed, you've simply matched the features of the loan to the way you actually manage your money. That's why I don't see a split loan as a compromise, and I certainly don't see it as sitting on the fence. In many cases it's actually the most considered decision a borrower can make, because they're recognising that different parts of their mortgage have different jobs to do.

The exact split is almost irrelevant. It might be eighty percent fixed and twenty percent variable, sixty-forty, or for someone else even the opposite, because there isn’t a universal formula and there isn’t a universal borrower. That’s why I rarely begin by talking about products, I want to understand the person sitting in front of me, how they manage their money, whether they’re disciplined savers, whether their circumstances may change, and whether they sleep better with certainty or feel comfortable riding out changes in the market if it means having more flexibility.

The answers to those questions tell me far more than trying to predict where interest rates might be this time next year, because at the end of the day, the ‘best’ home loan isn't the one that perfectly predicts the market, it's the one that's most suited to your lifestyle.

The Bottom Line

If you've made it this far, you've probably realised something, choosing a home loan isn't really about deciding whether fixed or variable is "better." It's about understanding your own financial habits and finding a loan structure that's most suitable for the way you live.

For years, the conversation around home loans has been framed as though borrowers only have two choices. You're either in the fixed camp or the variable camp, and the challenge is simply trying to work out which one will come out ahead over the next few years, personally, I don't think that's the most important question.

Interest rates will always move. Sometimes they'll rise faster than anyone expected, sometimes they'll fall sooner than the experts predicted, and every now and then they'll surprise everybody. Trying to build your entire mortgage around predicting those movements is incredibly difficult because, quite simply, nobody has a crystal ball, what we can understand, however, is you. We can understand how you manage your money, whether you value certainty over flexibility, how disciplined you are with savings, whether you expect your circumstances to change over the next few years, and what you want your home loan to achieve. Those are the things that should shape the way a loan is structured, because they're far more predictable than the next interest rate announcement.

I also hope this guide has shown that the conversation doesn't have to stop at fixed or variable. For many borrowers, a split loan isn't about sitting on the fence or trying to compromise, it's a considered strategy that allows different parts of the mortgage to perform different roles, balancing certainty where it's valuable, with flexibility where it's genuinely needed.

That doesn't mean everyone should have a split loan. Some borrowers will still be better suited to a fully fixed loan, while others may find a variable loan remains the most suitable option. The important point is that the recommendation should be based on your circumstances, not on what worked for somebody else or what the latest headline says interest rates might do next, that's one of the reasons I enjoy being a mortgage broker, the job isn't simply comparing interest rates or recommending whichever lender happens to have the sharpest pricing this week. It's about understanding the people sitting across the table, learning how they manage their finances and helping them structure a home loan that suits the way they live. Sometimes that leads to a fixed rate loan, sometimes it's variable, and quite often, it's a combination of both. Whatever the outcome, there should always be a reason behind the recommendation.

If there’s one thing I’d like you to take away from this guide, it’s this: don’t start by asking which loan is “best”, start by asking which loan structure is most suitable for your circumstances. Once you approach the decision that way, the conversation changes completely, because instead of trying to predict interest rates, you’re building a home loan around something far more important: your lifestyle, your goals and the way you manage your money.

At Your Home Loan Guy, I don’t believe every client should have the same home loan. I believe every client deserves a home loan that’s structured around the way they live.
