The Pros and Cons of Fixed, Variable and Split Loans

Choosing Your Rate Structure Affects More Than Monthly Repayments

Your rate structure shapes how much flexibility you have, what features you can access, and how exposed you are to rate movements. A variable loan gives you full access to offset accounts and unlimited extra repayments. A fixed loan locks in certainty but usually restricts how much you can pay ahead without penalty. A split loan gives you both, though managing two loan accounts requires more attention.

Variable Rate Loans Give You Full Flexibility

Variable rates move when lenders adjust their pricing, which typically follows the Reserve Bank's cash rate decisions but is not directly tied to them. Your repayments go up or down accordingly. In exchange for that uncertainty, you get flexibility. Most variable loans include an offset account, unlimited additional repayments, and no break costs if you decide to refinance or sell. You can also redraw funds you've paid ahead, though policies vary between lenders.

Consider a buyer in Moama purchasing a property just south of the river. They use a variable loan with an offset account and keep their income and savings in that offset. Every dollar in the account reduces the balance on which interest is calculated. Over a year, that can reduce the amount of interest charged by thousands of dollars, depending on the offset balance and loan amount. The flexibility matters if you're self-employed, commission-based, or expect irregular income.

Fixed Interest Rate Loans Provide Certainty for a Set Period

A fixed rate holds steady for a nominated term, typically one to five years. Your repayments stay the same regardless of what happens with broader rate movements. That certainty makes budgeting easier and protects you if rates rise during the fixed period. Once the fixed term ends, your loan automatically moves to the lender's standard variable rate unless you refinance or lock in a new fixed term.

Most fixed rate products limit extra repayments to around $10,000 to $30,000 per year. If you repay more than the allowed amount, break costs apply. 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, break costs can be significant. Offset accounts are rarely available on fixed rate loans, though some lenders offer a fixed rate with partial offset functionality at a slightly higher rate.

Split Loans Combine Both Structures

A split loan divides your borrowing between fixed and variable portions. You choose the proportions when you apply. Common splits are 50/50, but you can structure 70/30, 80/20, or any combination that suits your situation. The fixed portion gives you repayment certainty on part of your debt. The variable portion retains full flexibility, including offset access and unlimited extra repayments.

Each portion is a separate loan account with its own balance, rate, and repayment schedule. You make two repayments each month, or your lender may combine them into a single debit. Loan statements show both accounts. If you want to adjust the split later, you'll need to refinance or refix, which may involve discharge and application costs.

How Rate Movements Affect Each Structure Differently

When rates fall, variable loan holders benefit immediately through lower repayments. Fixed rate holders continue paying the higher locked-in rate until their term expires. When rates rise, fixed rate holders are protected for the remainder of their term, while variable borrowers face higher repayments straight away. Split loan holders experience both outcomes in proportion to their split.

Rate cycles rarely move in one direction for extended periods. Locking in a fixed rate near the peak of a rate cycle delivers substantial savings. Fixing near the bottom of a cycle means you miss out on potential cuts. Predicting rate movements consistently is difficult, even for economists.

Moama Buyers Often Split Because of Proximity to Major Employment Hubs

Moama sits across the Murray from Echuca, with many residents working on either side of the river. Income stability varies depending on employment type and industry. Seasonal work, hospitality, agriculture, and tourism all have different cash flow patterns. A split structure works for buyers who want certainty on part of their repayments but need flexibility to make extra repayments when income allows. The variable portion also gives access to an offset account, which is useful if you're managing business income, seasonal work, or commission payments.

If you're relocating to Moama for work or family reasons, a mortgage broker in Echuca can help you compare lenders and structure a loan that accounts for your employment type and deposit position.

What Happens at the End of a Fixed Term

When your fixed term ends, your loan reverts to the lender's standard variable rate. That rate is typically higher than the lender's current advertised variable rate, which includes discounts for new borrowers. You can avoid the standard variable rate by refinancing to a new lender or negotiating a new fixed or variable rate with your current lender before the fixed term expires. Most lenders allow you to lock in a new rate up to 90 days before your fixed term ends, though policies differ.

If you're within six months of a fixed term ending, a fixed rate expiry review can identify whether staying with your current lender or switching will deliver lower ongoing repayments.

Interest Only Versus Principal and Interest Applies Across All Rate Types

You can choose interest only or principal and interest repayments on variable, fixed, or split loans. Interest only reduces your monthly repayment during the interest only period because you're not paying down the loan balance. The lower repayment can help with cash flow in the short term, particularly for investment loans where maximising tax deductions is a priority. Principal and interest repayments reduce your loan balance over time and build equity faster.

Interest only periods are typically approved for one to five years. After that, your loan reverts to principal and interest, and your repayment increases to account for the shorter remaining loan term. Some lenders cap interest only lending at 80 per cent loan to value ratio, particularly for owner occupied borrowing.

How Lenders Assess Serviceability on Each Loan Type

Lenders assess your ability to service a home loan at a rate that is at least 3.0 percentage points above the product rate. That buffer applies whether you're applying for a variable, fixed, or split loan. For a split loan, each portion is assessed separately, then combined to determine total serviceability. If you're applying for an interest only loan, most lenders assess serviceability on a principal and interest basis to confirm you can afford the higher repayment once the interest only period ends.

If you're refinancing, the same serviceability assessment applies. Lenders will reassess your income, expenses, and existing debts as if you were a new borrower.
