When you’re taking out a home loan, one of the first decisions you’ll face is whether to choose a fixed vs variable home loan structure. Both options have their place, and the right choice depends on your financial situation, your tolerance for rate movements, and how you expect to manage your loan over time. Understanding the key differences can help you have more productive conversations with your mortgage broker.
A fixed rate home loan locks in your interest rate for a set period, typically between one and five years. During this time, your repayments stay the same regardless of what happens to the broader interest rate environment.
The main appeal of a fixed rate is predictability. Knowing exactly what your repayments will be each month can make budgeting simpler, particularly if you’re managing a tight household budget or prefer certainty in your financial planning.
If variable rates were to rise during your fixed period, you would be protected from those increases until your fixed term ends.
Fixed rate loans often come with restrictions. Many lenders limit additional repayments, sometimes capping them at a certain amount per year or charging fees if you exceed that cap. If you need to break your fixed rate early, perhaps to refinance, sell your property, or access equity, you may face break costs. These costs can be substantial depending on the remaining term and how rates have moved since you fixed.
It’s also worth noting that if variable rates fall during your fixed period, you won’t benefit from those reductions until your term ends and you renegotiate or move to a variable rate.
With a variable rate loan, your interest rate can change over time. These changes typically reflect movements in the cash rate set by the Reserve Bank of Australia, though lenders also adjust rates based on their own funding costs and business decisions.
Variable loans generally offer more flexibility. Most allow unlimited additional repayments without penalty, which can help you pay off your loan faster and reduce the total interest you pay over time. Features like offset accounts and redraw facilities are more commonly available with variable products.
If interest rates decrease, your repayments may reduce accordingly, though this isn’t guaranteed and depends on your lender passing on rate changes.
The flipside of flexibility is uncertainty. If rates rise, your repayments will increase, which could put pressure on your budget. Borrowers choosing variable rates need to be comfortable with this possibility and ideally have some buffer in their finances to absorb potential increases.
Some borrowers choose to split their loan, fixing a portion while keeping the rest variable. This approach may provide a degree of repayment certainty on the fixed portion while maintaining flexibility on the variable portion.
Split loans can be structured in different ways, with varying proportions allocated to each rate type. The right split, if any, depends on your individual circumstances and what you’re hoping to achieve with your loan structure.
Keep in mind that split loans may involve managing what are effectively two separate loan accounts, each with their own terms and conditions.
When weighing up a fixed vs variable home loan, consider the following:
Your cash flow: How much flexibility do you have if repayments were to increase? Do you have savings or income buffer to manage potential rate rises?
Your plans for the property: Are you likely to sell, renovate, or refinance within the next few years? These actions could trigger break costs on a fixed loan.
Your repayment strategy: Do you plan to make additional repayments? If so, a variable loan or a fixed loan with generous additional repayment terms might suit you better.
Your comfort with uncertainty: Some people prefer the certainty of knowing their repayments, even if it means potentially paying more over time. Others are comfortable accepting rate variability in exchange for flexibility.
There’s no universally correct answer. What works for one borrower may not suit another, which is why it’s important to consider your own objectives, financial situation, and needs before making a decision.
Choosing between fixed and variable rates is just one of many decisions involved in taking out a home loan. The right structure depends on factors personal to you, from your income stability to your future plans.
