Beginner's Guide to Fixed, Variable & Split Loans

Fixed, variable, and split loans each lock you into different trade-offs between certainty and flexibility. A fixed rate protects you from rate rises but costs you access to features like offset accounts. A variable rate gives you full access to every feature but exposes you to rate movement. A split loan tries to give you both, but you pay two sets of fees and manage two loan accounts.

Fixed Rate Loans Lock Your Rate and Your Features

A fixed rate loan holds your interest rate at the same level for a set period, usually between one and five years. The rate you agree to at settlement is the rate you pay until the fixed term ends, regardless of what the Reserve Bank does.

The protection costs you features. Most lenders restrict or remove offset accounts on fixed portions. Redraw facilities may be limited or come with processing delays. Extra repayments are usually capped at $10,000 to $20,000 per year, and exceeding that cap triggers break costs. If you sell or refinance before the fixed term ends, you may pay break costs calculated on the difference between your fixed rate and the lender's wholesale cost of funds at the time you exit.

Consider a buyer who fixes at 5.8% for three years. Eighteen months later, rates have dropped to 5.0% and they want to refinance. The lender has priced the remaining term of their fixed loan at current wholesale rates. The difference between what the buyer is paying and what the lender can now earn on that money becomes the break cost. Depending on the loan size and rate gap, that figure can run into tens of thousands of dollars. That same buyer would have faced no penalty on a variable loan.

Variable Rate Loans Give You Features and Exposure

A variable rate moves when your lender decides to move it, usually in response to official cash rate changes but not always in lockstep. Your repayments go up when rates rise and fall when rates drop.

You get full access to offset accounts, unlimited extra repayments, and unrestricted redraw. If you refinance or sell, no break costs apply. If your income increases or you receive a bonus, you can pay down the loan faster without penalty. For buyers who want control and plan to make extra repayments, variable loans deliver the most flexibility.

The risk is repayment shock. A buyer who can comfortably afford repayments at 5.5% may struggle at 6.5%. Rate movements happen faster than income growth, and buyers who stretch their budget at the time of purchase often find themselves under pressure when rates climb.

Split Loans Divide Your Loan Into Two Accounts

A split loan divides your total borrowing into a fixed portion and a variable portion. You nominate the split, commonly 50/50 but it can be any ratio. Each portion operates as a separate loan account with its own interest rate, features, and terms.

The fixed portion behaves exactly like a standalone fixed loan with the same feature restrictions and break cost risks. The variable portion gives you full access to offset and extra repayments. The idea is that you reduce exposure to rate rises without giving up all your flexibility.

You pay two sets of fees. Most lenders charge an annual fee per loan account, so a split loan means two fees instead of one. Some lenders charge two application fees at settlement. You also manage two redraw balances, two statements, and two interest calculations. That adds administrative load, but for buyers who value partial protection and partial flexibility, the trade-off makes sense.

In our experience, buyers who split usually put the larger portion on variable and the smaller portion on fixed. That keeps most of their loan accessible while locking in some certainty. A buyer borrowing $600,000 might fix $200,000 for three years and leave $400,000 on variable with a full offset account attached.

How First Home Buyers Should Choose Between Loan Types

Your choice depends on three things: how much rate movement you can absorb, whether you will make extra repayments, and how long you plan to hold the loan.

If your budget has no room for rate rises and you plan to stay in the property for at least three years, a fixed rate gives you certainty. If you expect to receive irregular income, bonuses, or gifts that you want to put toward the loan, a variable rate with offset gives you the flexibility to reduce interest without losing access to your money. If you want partial protection and partial flexibility, a split loan does both but costs more in fees.

First home buyers in Queensland using the Australian Government 5% Deposit Scheme with a 5% deposit often choose variable loans with offset accounts because they expect to build their savings buffer after settlement and want the offset to reduce their interest cost immediately. Buyers using a fixed rate in that scenario lose the benefit of the offset and pay interest on the full loan balance even as they rebuild savings in a separate account.

You also need to factor in your borrowing capacity. Lenders assess your ability to service a loan at a rate higher than the actual rate you will pay, usually by adding a buffer of around 3%. A fixed rate does not change that assessment. You are tested at the buffered rate regardless of whether you fix or go variable, so fixing does not increase the amount you can borrow.

What Happens When a Fixed Rate Ends

When your fixed term expires, your loan automatically converts to your lender's standard variable rate unless you take action. That standard variable rate is almost always higher than the discount variable rate the lender offers to new customers.

Most borrowers refinance or renegotiate before the fixed term ends to avoid reverting to the standard rate. If you want to stay with your current lender, contact them at least 90 days before expiry and ask for their retention rate. If you want to switch lenders, start the refinancing process 120 days out so the new loan settles on or shortly after your fixed term ends. That way you avoid break costs and avoid paying the standard variable rate.

Buyers often assume their lender will automatically offer them a good rate when the fixed term ends. That does not happen. You need to ask, or you need to move.

If you are still within the first year or two of your first home loan, check whether your current lender will let you refix without a full refinance. Some lenders treat it as a variation rather than a new application, which saves time and cost. Others require a full refinance process even if you are staying with them. Know the process before your fixed term ends so you are not making decisions under time pressure.

Rates move, your income changes, and your priorities shift. The loan type that made sense two years ago may not make sense now. Lock in certainty if you need it, keep flexibility if you will use it, and split the difference if neither extreme fits. Just make sure you understand what you are giving up and what you are paying for.
