Simple hacks to choose fixed, variable, or split loans

How fixed, variable, and split loans work

A fixed loan locks your rate for a set period, usually between one and five years. A variable loan moves with the market, which means your repayments can change when lenders adjust their rates. A split loan divides your borrowing between fixed and variable portions, often fifty-fifty, though you can choose any ratio that suits your situation.

Consider a buyer refinancing a $500,000 loan. They fix half at a set rate for three years and leave the other half variable. The fixed portion protects them from rate rises on $250,000 of debt, while the variable portion lets them make extra repayments without penalty and access an offset account on the remaining $250,000. If rates fall, they benefit on half the loan. If rates rise, they're protected on the other half.

Each structure changes what you can do with your loan once it settles. Fixed loans typically don't allow extra repayments beyond a small annual threshold, often $10,000 to $30,000 depending on the lender, and most don't come with an offset account. Variable loans allow unlimited extra repayments and usually offer a linked offset, which can reduce the interest you pay without locking funds away. A split loan combines both, giving you partial rate certainty and partial flexibility.

When a fixed loan works for buyers in Newcastle

A fixed loan suits buyers who value predictable repayments and don't plan to make large extra repayments during the fixed term. If your income is consistent and your budget tight, knowing exactly what you'll pay each fortnight removes one source of uncertainty.

In our experience, buyers who stretch their borrowing capacity to purchase in suburbs like Merewether, The Junction, or Hamilton often prefer fixed loans. At current lending serviceability buffers of 3.0 percentage points above the loan rate, a buyer approved at the maximum amount has limited room for rate increases. Fixing the loan for two or three years provides breathing space to build equity and improve their position before the fixed term ends.

Fixed loans come with conditions. Most lenders charge break costs if you exit the loan early, refinance, or sell the property before the fixed period ends. Break costs are calculated based on the difference between your fixed rate and the lender's current wholesale funding cost for the remaining term. If rates have fallen since you fixed, the break cost can run into thousands of dollars. If rates have risen, the break cost may be zero or close to it.

Variable loans and when they make sense

A variable loan gives you access to all the features most buyers want. Unlimited extra repayments let you pay down the loan faster when you have surplus income. A mortgage offset account linked to the loan reduces the interest you're charged without tying up your cash, which is particularly useful if you're saving for renovations, holding a deposit for an investment property, or building a buffer for parental leave.

Buyers who receive bonuses, commissions, or irregular income often benefit from a variable loan. If you're earning $120,000 with a $30,000 annual bonus, putting that bonus into an offset account reduces your interest bill immediately. You keep full access to the funds, but the lender calculates interest as though your loan balance is lower by the offset account balance.

The risk with a variable loan is exposure to rate movements. A borrower with a $600,000 variable loan at current owner-occupied rates would see fortnightly repayments increase by around $80 for every 0.25 percentage point rise. Over twelve months, that's roughly $2,000 in additional repayments per quarter point. Buyers using variable loans need enough margin in their budget to absorb those increases or enough in their offset to cushion the impact.

Split loans for Newcastle buyers who want both

A split loan divides your borrowing into two accounts. One portion is fixed, the other variable. You choose the ratio. Most buyers split evenly, but you can fix 70% and leave 30% variable, or any other combination that matches your priorities.

This structure works well for buyers who want protection from rate rises but still need access to offset accounts and the ability to make extra repayments. In a scenario where a buyer borrows $650,000 to purchase in Adamstown or Kotara, they might fix $400,000 for three years and leave $250,000 variable. The fixed portion anchors their repayments on the larger part of the debt. The variable portion gives them access to an offset account and lets them direct extra repayments to reduce the loan faster.

One detail that catches people out is that you're managing two loans, not one. Each portion has its own account number, its own repayment schedule, and often its own monthly fee. Some lenders charge a package fee that covers both, while others charge separately. You'll also need to decide how to allocate extra repayments between the two portions, because most lenders won't split them automatically.

How offset accounts fit with each structure

An offset account is a transaction account linked to your home loan. The balance in the offset is subtracted from your loan balance before interest is calculated, which means every dollar in offset saves you interest at your loan rate. Offset accounts are almost always available on variable loans and on the variable portion of a split loan. They're rarely available on fixed loans, though some lenders offer partial offset with restrictions.

If you're holding cash for any reason, whether it's an emergency fund, savings for a holiday, or income tax reserves, keeping that cash in an offset account instead of a standard savings account can save you thousands of dollars a year. A buyer with a $500,000 variable loan and $50,000 sitting in an offset account pays interest on $450,000, not $500,000. That difference compounds over time.

For first home buyers using the Australian Government 5% Deposit Scheme, offset accounts provide a way to build equity faster once the loan settles. If you're borrowing at an LVR above 80% without paying LMI thanks to the government guarantee, directing your savings into an offset reduces your effective loan balance and accelerates the point at which you reach 80% LVR, opening up options to refinance or negotiate a lower rate.

Comparing loan structures before you apply

Before you settle on a structure, work through what you're actually going to do with the loan. Are you planning to make extra repayments? Do you have savings you want to keep liquid? Do you need certainty around repayments, or can you handle some variation?

A borrowing capacity assessment shows you what you can borrow, but it doesn't tell you which structure fits your circumstances. If you're approved for $700,000 and you're borrowing the full amount, a split or fixed loan reduces your exposure to rate movements. If you're borrowing $500,000 but earning enough to service $700,000, a variable loan with offset gives you room to move and tools to reduce interest without penalty.

Lenders assess your serviceability at a rate 3.0 percentage points above the loan product rate, regardless of whether you choose fixed, variable, or split. That buffer is there to ensure you can still afford the loan if rates rise. It doesn't change based on your loan structure, but your actual repayment flexibility does.

What happens when a fixed term ends

When your fixed term expires, the loan reverts to the lender's standard variable rate unless you actively choose another option. The standard variable rate is almost always higher than the discounted variable rate offered to new borrowers, sometimes by 0.50 to 1.00 percentage points or more.

This is the point where most borrowers either renegotiate with their current lender or refinance to a new lender. If you've built equity, reduced your LVR, or improved your financial position since the loan settled, you're often in a position to negotiate a lower rate or access a loan product with enhanced features. Some lenders will automatically offer you a new fixed rate, but you're not obliged to accept it. You can switch to variable, refix at a different rate or term, or move to a different lender entirely.

If you're approaching the end of a fixed term and unsure what to do next, a fixed rate expiry review helps you compare your options and avoid rolling onto an uncompetitive rate by default.

Newcastle buyers often ask whether they should refix if they're planning to sell within the next year or two. If a sale is likely, switching to variable or accepting a higher rate on a month-to-month basis may cost less than paying break costs later. If you're staying put, refixing or negotiating a discounted variable rate usually makes sense.

Getting the right structure means matching the loan to how you'll use it, not just what sounds appealing at application. Call one of our team or book an appointment at a time that works for you.
