Unlock the Secrets to Fixed, Variable and Split Loans

Choosing between a fixed rate, variable rate, or split loan comes down to how much rate certainty you need versus how much flexibility you want with repayments and features.

How Variable Rate Home Loans Work

A variable rate home loan adjusts whenever your lender changes their rates, which usually follows movements from the Reserve Bank but can also shift independently. You pay more when rates rise and less when they fall, and you have access to features like offset accounts and the ability to make extra repayments without penalty.

Consider a buyer refinancing an owner-occupied loan with $450,000 remaining. They link a full offset account and park $30,000 in it from their savings. Interest is charged only on the net balance of $420,000, which reduces the total interest paid over the life of the loan and shortens the loan term without changing the scheduled repayment amount. If they receive a work bonus or tax return, they can deposit it into the offset and reduce interest further, then withdraw it later if needed without restriction.

Variable loans are suited to borrowers who want to pay down debt faster, who maintain a buffer in savings, or who expect rates to fall or remain stable. The offset feature is particularly valuable in Queensland, where many buyers work in industries with seasonal income patterns or irregular bonuses and want the ability to reduce interest without locking funds away.

How Fixed Rate Home Loans Work

A fixed rate home loan locks your interest rate for a set period, typically between one and five years. Your repayment amount stays the same regardless of what happens in the broader market, which makes budgeting more predictable.

Fixed loans generally don't include offset accounts, and extra repayments are capped at around $10,000 to $30,000 per year depending on the lender. If you break the loan early by refinancing, selling, or paying it out in full before the fixed term ends, you may be charged break costs. These costs reflect the lender's funding loss and can range from a few hundred dollars to tens of thousands, depending on how much rates have moved since you fixed and how much time remains on the term.

Fixed rates appeal to buyers who prioritise certainty over flexibility, who are stretching their budget, or who believe rates will rise during the fixed period. They're common among first home buyers using schemes like the Australian Government 5% Deposit Scheme where repayment stability is a priority in the early years of ownership.

What Is a Split Loan and How Does It Work

A split loan divides your total borrowing into two portions: one fixed and one variable. You choose the split, commonly 50/50 but it can be any proportion that suits your situation. Each portion operates independently with its own rate, terms, and features.

The variable portion gives you access to an offset account and unlimited extra repayments. The fixed portion provides rate protection and stable repayments. You're not locked into one strategy, and you can adjust the split at the end of the fixed term when you refinance or roll onto a new rate.

In our experience, buyers with irregular income or those holding cash reserves benefit from keeping at least 50% of the loan variable so they can make full use of an offset account. If you're refinancing and want to learn how your current loan compares, a loan health check shows whether your rate, features, and structure still match your circumstances.

Choosing the Right Structure for Your Situation

Your loan structure should match your financial behaviour, not just your forecast. If you're disciplined with savings and regularly hold a balance that could sit in an offset, a variable or split loan will outperform a fixed loan even if rates rise slightly. If your income is steady and you prefer to set repayments and forget them, a fixed loan removes the need to monitor rate movements.

Property type also matters. Investors often favour variable loans because the offset account can be used to separate income and expenses, and extra repayments provide flexibility to manage multiple properties or prepare for portfolio expansion. Owner-occupiers stretching their budget may lean toward a fixed rate for the first few years, then switch to variable once they've built equity and have more breathing room. You can read more about the differences in approach in our investment loans guide.

Split loans work when you want both outcomes: protection against rate rises and the ability to reduce interest through an offset or extra repayments. The structure is common among Queensland buyers purchasing in suburbs like Morningside, Hawthorne, or Bulimba, where property values and loan sizes make rate certainty valuable but the buyer still wants control over how quickly they reduce the debt.

What Happens When Your Fixed Rate Ends

When the fixed period ends, your loan automatically rolls onto the lender's variable rate unless you refinance or negotiate a new fixed term. The revert rate is often higher than the lender's advertised variable rate for new customers, and you lose the certainty that made the fixed loan appealing in the first place.

Most borrowers refinance around 90 days before the fixed term ends to lock in a new rate without a gap. If you're inside the fixed term, break costs apply. If you've rolled onto the variable revert rate, you can refinance or switch lenders without penalty. We regularly see this with clients coming off fixed terms set two or three years ago when rates were lower. The revert rate can be 1% or more above what's available elsewhere, which on a $500,000 loan adds more than $5,000 a year in interest. You can get ahead of this by setting a reminder six months before your fixed term expires, or by working with a broker who tracks your loan and contacts you when it's time to review.

Interest Rate Discounts and How They're Applied

Lenders advertise a base rate and then apply discounts depending on your loan size, deposit, and whether the loan is for an owner-occupier or investor. The discount is commonly between 0.5% and 1.5%, and it's negotiated at the time of approval. If you're refinancing, the discount may be higher because lenders compete harder for external customers than they do to retain existing ones.

Discounts apply differently to fixed and variable loans. On a variable loan, the discount is ongoing and follows the loan for its life unless the lender changes their policy or you fall outside the eligibility criteria. On a fixed loan, the discount is baked into the fixed rate you're quoted, and when the fixed term ends, you'll revert to the standard variable rate with a new discount applied based on the lender's criteria at that time.

If you're comparing home loan rates, focus on the comparison rate as well as the advertised rate. The comparison rate includes fees and gives a more accurate picture of the total cost over the loan term. Some lenders advertise a low headline rate but charge higher ongoing fees or lower discounts, which makes the loan more expensive overall.

Portable Loans and Moving Property

A portable loan lets you transfer your existing home loan to a new property without breaking the contract or paying discharge fees. This feature is valuable if you're on a fixed rate and want to sell and buy again before the fixed term ends, or if you've negotiated a strong discount and don't want to lose it by refinancing.

Not all lenders offer portability, and those that do often require the new property to meet their lending criteria at the time of transfer. If the new property is more expensive and you need to borrow more, the additional amount will be assessed as a top-up and may be subject to a different rate. If the new property is cheaper and you're repaying part of the loan, break costs may still apply to the amount being discharged even though the loan itself remains open.

Portability is more common among buyers who know they'll move within a few years, such as Defence families or workers relocating for contracts. If you're purchasing in Queensland and expect to move interstate or upgrade within the fixed term, confirm portability before signing.
