Fixed vs Variable Home Loans: Understanding Your Mortgage Options in Perth

Published:

May 22, 2025

Choosing between a fixed or variable home loan is one of the biggest decisions you’ll make when buying your first home in Perth. Each option has unique benefits that impact your financial future in different ways. 

The right choice depends on your personal circumstances, financial goals, and how much certainty you need in your budgeting. Variable loans offer flexibility with changing interest rates that go up or down with market conditions. When rates fall, you’ll pay less, but when they rise, your repayments increase. Fixed loans, on the other hand, lock in your interest rate for a set period, usually between 1-5 years, giving you predictable repayments regardless of market changes.

Many first home buyers in Perth choose a split loan option, which divides your mortgage into part fixed and part variable portion. 

Key Differences

Fixed loans offer payment stability and protection from rate increases, while variable loans provide flexibility and potential savings when interest rates fall.

Your financial situation, risk tolerance and market outlook should guide your decision between fixed and variable home loans.

Split loans combine features of both loan types, giving you a balanced approach that many first home buyers find appealing.

Understanding Fixed and Variable Home Loans

When shopping for a home loan, you’ll need to choose between fixed and variable interest rates. Each option has unique features that significantly impact your mortgage repayments over time.

What Is a Fixed Rate Home Loan?

A fixed-rate home loan locks in your interest rate for a set period, typically between 1-5 years. During this fixed term, your loan repayments remain the same regardless of what happens to interest rates in the broader economy.

This stability makes budgeting easier as you’ll know exactly how much your mortgage payments will be each month. Many first home buyers in Perth prefer fixed loans for this predictability.

The main benefit is protection against interest rate rises. If rates increase, you won’t be affected until your fixed term ends.

However, fixed-rate home loans have limitations. You may face break fees if you want to refinance or pay off your loan early. Additionally, if interest rates fall, you won’t benefit from lower repayments until your fixed rate period expires.

What Is a Variable Rate Home Loan?

Variable-rate loans have an interest rate that moves up or down in response to market conditions, typically following the Reserve Bank of Australia’s cash rate decisions.

These loans offer more flexibility than fixed interest rate options. You can make extra repayments without penalties, potentially reducing your loan term and saving on interest costs.

Variable home loans often come with helpful features like offset accounts and redraw facilities. These features help you save interest while maintaining access to your funds.

The downside is less certainty. Your repayments can increase when interest rates rise, making budgeting more challenging. This unpredictability could be stressful for first home buyers on tight budgets.

How Home Loan Interest Rates Work

Interest rates represent the cost of borrowing money from a lender. For home loans, this is calculated as a percentage of your remaining loan balance.

Banks determine their rates based on several factors:

  • The RBA cash rate
  • Funding costs in international markets
  • Competition among lenders
  • Risk assessment of borrowers

Your personal circumstances also influence the rate you’re offered. Factors include:

  • Your deposit size (loan-to-value ratio)
  • Credit history
  • Employment stability
  • The type of property you’re buying

Interest can be calculated daily, but charged monthly on most home loans. This means making extra repayments reduces your interest costs immediately.

Understanding the comparison rate is crucial. This figure includes both the interest rate and most fees, giving you a more accurate picture of the loan’s true cost.

Comparing Features of Fixed vs Variable Home Loans

When choosing a home loan, understanding the key differences between fixed and variable options can save you thousands over the life of your loan. Each type offers distinct advantages that may suit different financial situations and goals.

Repayments and Flexibility

Fixed-rate loans provide certainty with consistent repayments throughout the fixed term, typically 1-5 years. Your monthly repayments remain the same regardless of market fluctuations, making budgeting more straightforward.

Variable loans offer more flexibility but come with less certainty. Your repayments may increase or decrease as interest rates change. When the Reserve Bank cuts rates, you could benefit immediately with lower repayments.

For first home buyers in Perth, fixed rates can be appealing during the initial years of homeownership when budgets might be tighter. However, if you expect your income to increase or want to take advantage of potential rate drops, a variable option might suit you better.

Offset and Redraw Facilities

Variable loans typically offer more comprehensive access to money-saving features. Most variable loans come with an everyday offset account, which allows you to reduce interest charges by keeping your savings or salary in an account linked to your loan.

For example, if you have a $400,000 loan and $50,000 in your offset account, you’ll only pay interest on $350,000.

Redraw facilities are also more common with variable loans, letting you access extra payments you’ve made. While some fixed loans offer redraw, they often have stricter limits on how much you can withdraw.

First home buyers should note that these features significantly reduce their interest costs over time, potentially saving thousands throughout their loan term.

Extra Repayments and Early Payment Options

Variable loans typically allow unlimited extra repayments without penalties. This flexibility helps you reduce your principal faster and save on interest costs when you have spare cash.

Fixed loans usually restrict extra repayments to a certain amount per year (often $10,000-$20,000). Exceeding this limit may trigger break fees.

Early repayment of fixed loans results in substantial break costs, especially if interest rates have fallen since you fixed your rate. These costs protect lenders from lost interest revenue.

For Perth first home buyers, consider how likely you are to make extra repayments. If you expect bonuses or inheritance, a variable loan might better accommodate these lump-sum payments without penalties.

Eligibility and Application Process

The eligibility criteria for fixed and variable loans are generally similar, focusing on your:

  • Income stability and employment history
  • Credit score and existing debts
  • Deposit size (ideally 20% to avoid Lenders Mortgage Insurance LMI)
  • Property value and location

You can apply online for most loans, though the process varies slightly between types. Fixed-rate applications sometimes require quicker processing as rates can change before approval.

Variable loans might have more flexible approval criteria in some cases. Many Perth lenders offer specialised first home buyer programs with either loan type, potentially including lower deposit requirements or fee waivers.

Remember to compare the comparison rate rather than just the advertised rate, as this includes most fees and charges associated with the loan.

Pros and Cons of Fixed and Variable Rate Home Loans

Choosing between fixed and variable rate home loans involves weighing certainty against flexibility. Each option offers distinct advantages that might align better with your financial situation and goals.

Advantages of Fixed Rate Home Loans

Fixed-rate loans provide predictability for your budget. When interest rates are locked in, your repayments stay the same throughout the fixed period, typically between 1-5 years.

This stability makes financial planning easier. You’ll know exactly how much to set aside for your mortgage each month, which helps with budgeting for other expenses.

For first home buyers in Perth, this certainty is particularly valuable. You won’t face sudden payment increases if the Reserve Bank raises interest rates multiple times.

Fixed loans sometimes offer useful features like offset accounts, though these typically come with additional fees. Some lenders also provide cashback offers when you sign up for a fixed rate, which could mean thousands back in your pocket.

Drawbacks of Fixed Rate Home Loans

Fixed loans generally have higher starting interest rates compared to variable options. You’re essentially paying extra for the security of rate protection.

These loans offer less flexibility with additional repayments. Many lenders cap how much extra you can contribute, limiting your ability to pay down your mortgage faster.

Break fees can be substantial if you need to exit the loan during the fixed period. These costs might apply if you sell your home or want to refinance to a better deal.

Most fixed loans don’t offer the full range of features that variable loans do. Features like 100% offset accounts are either unavailable or come with significant fees attached.

Benefits of Variable Rate Home Loans

Variable loans typically start with lower interest rates than fixed options, meaning smaller initial repayments for your Perth home purchase.

These loans offer excellent flexibility for making extra repayments. You can put any windfall or savings directly toward reducing your principal, potentially saving thousands in interest over time.

Full-featured offset accounts are standard with variable loans. By keeping your savings in an offset account, you’ll reduce the interest calculated on your loan balance.

When interest rates fall, your repayments decrease automatically. This means you could benefit from rate cuts without needing to refinance.

Variable loans rarely have break fees, making it easier to sell your property or refinance to a better deal if circumstances change.

Risks of Variable Rate Home Loans

Your repayments can increase when interest rates rise. This uncertainty makes budgeting more challenging, especially for first home buyers on tight budgets.

The lack of certainty might cause financial stress. Not knowing if or when your repayments might increase can be worrying, especially if you’re struggling to meet current obligations.

Interest-only periods on variable loans might seem attractive initially, but lead to higher repayments later. When the interest-only period ends, your repayments will increase substantially as you begin paying down the principal.

Choosing the Right Home Loan for Your Situation

Selecting the most suitable home loan requires understanding your financial situation and how different loan types match your needs. The right choice could save you thousands over the life of your loan.

It completely depends on each individual’s situation. It’s best to talk to an expert to get guidance on what is right for the client. A home loan that works well for one buyer might not suit another, especially when personal goals, risk appetite, and plans vary widely.

How Market Factors Influence Home Loan Rates

Home loan rates in Australia respond directly to economic conditions. When the Reserve Bank of Australia adjusts the cash rate, lenders typically follow suit with their variable rates. Fixed rates, however, are influenced by longer-term market forecasts.

Inflation plays a crucial role in these decisions. When inflation rises, the Reserve Bank often increases the cash rate to control spending, which pushes up variable loan rates.

The comparison rate is your best tool for understanding true costs, as it includes fees and charges beyond the advertised rate. This gives you a more accurate picture than the headline rate alone.

Market competition among lenders also drives rates down, which is why smaller lenders sometimes offer more competitive rates.

Refinancing and Switching Loans

Refinancing can be a smart financial move when your circumstances change or better deals become available. Many borrowers refinance to secure lower interest rates, potentially saving thousands over the loan term.

The refinancing process involves settling your current loan and establishing a new one. While there are costs involved (discharge fees, application fees, and possibly break costs for fixed loans), the long-term savings often outweigh these expenses.

A home loan expert helps you calculate whether refinancing makes financial sense by comparing your current loan’s comparison rate against potential new loans, accounting for all switching costs.

Split Loan Options

Split loans offer a balanced approach by dividing your mortgage into part fixed and part variable portion. This gives you both stability and flexibility in your repayments.

With a split loan, you lock in a portion of your loan at a fixed rate for protection against rate rises, while keeping the remainder variable to take advantage of rate decreases and additional features.

The reference rate for each portion works independently, so you’ll have different interest calculations on each part. This structure lets you make extra repayments on the variable portion while maintaining certainty on your fixed component.

Factors to Consider Before Deciding

Your financial situation should guide your loan choice. If you’re on a tight budget, a fixed-rate Simple Home Loan provides payment certainty for easier budgeting.

Your planned duration in the property matters too. If you might sell within a few years, variable loans typically offer more flexibility and fewer exit fees.

Future interest rate forecasts from the Reserve Bank of Australia should influence your decision. If rates are expected to rise, fixing might be advantageous. If they’re predicted to fall, variable loans could save you money.

Consider your need for features like offset accounts and redraw facilities. These are typically more available with variable loans but come at a premium compared to basic products.

Your risk appetite is important. Variable loans offer potential savings but with less certainty, while fixed loans provide stability but might cost more if market rates drop.
