Fixed vs Variable Home Loan in Australia: Four Borrowers, Four Answers

Last reviewed: October 2026 · Updated after each RBA decision · By the MortgageCompass Editorial Team · How we research

Right now, fixed and variable home loans in Australia cost almost the same. On October 2, 2026, Canstar’s average owner-occupier variable rate was 6.63%, against 6.56% for a two-year fix and 6.61% for three years. That is unusual, and it changes the question. You are not choosing the cheaper rate; you are choosing between certainty and flexibility, at a time when the Reserve Bank of Australia has raised the cash rate four times this year, to 4.60%.

There is no single right answer, so this guide gives four, one for each of the borrowers we hear from most. Find the one closest to you, then use the split loan mixer to test your own numbers.

Four borrowers, four answers

🔑
The stretched first home buyer
Repayments already take a big share of the budget
MOSTLY OR FULLY FIXED
If another rate rise would force you to cut back on essentials, fixing for two or three years buys certainty while your income grows. With fixed rates level with variable today, that certainty costs very little. Keep a small variable portion if you want an offset account for your emergency savings. Check government schemes in our guide to home loans for first home buyers.
💰
The saver with a big offset balance
Tens of thousands of dollars sitting in savings
MOSTLY VARIABLE
Every dollar in an offset account reduces the balance you pay interest on. At 6.63%, $50,000 in offset saves about $3,300 a year in interest, and that saving is not taxed as income. Most fixed loans do not offer a full offset, so fixing everything would waste that benefit. A small fixed portion can still cap part of your risk.
🏠
The upgrader who may sell soon
Might move or refinance within two years
VARIABLE
Breaking a fixed loan early can trigger break costs, which can run to thousands of dollars if rates have fallen since you fixed. A variable loan lets you sell, refinance or pay off a lump sum without that risk. If you do fix, ask whether the loan is portable to a new property.
📈
The property investor
Wants flexibility and cash flow across several loans
SPLIT, OFTEN WITH A VARIABLE CORE
Investors often keep part of each loan variable for redraw, offset and extra repayments, and fix part to make cash flow predictable. Investor rates are usually higher than the owner-occupier averages above. How interest, redraw and offset accounts interact with tax deductions is complex, so speak to a tax adviser before you structure an investment loan.

Try your own split

Most Australian lenders let you split one loan into a fixed and a variable part, in whatever proportion you choose. Move the slider to see how your mix behaves if the RBA cuts, holds or keeps raising rates over the next three years.

30-year principal and interest loan, monthly repayments. Scenarios over three years: cuts of 0.25 points in months 4 and 10; no change; or rises of 0.25 points in months 2, 5 and 9. Lenders pass changes on in full here; in reality they may not. The offset balance is linked to the variable part only, as most fixed loans do not allow a full offset. Default rates are Canstar averages for October 2, 2026. Not financial advice.

With the default figures and $20,000 in offset, an all-variable loan costs less than fixing if rates hold or fall, but about $7,000 more over three years if the RBA raises the cash rate three more times. A 50/50 split cuts that swing roughly in half. The right balance depends on how much a bad outcome would hurt your budget, not on guessing the next decision.

What else to check before you choose

  • Extra repayments: variable loans usually allow unlimited extra repayments. Fixed loans often cap them, commonly around $10,000 a year, and may charge for more.
  • Redraw and offset: usually full on variable loans, limited or unavailable on many fixed loans.
  • Break costs: leaving a fixed loan early can be expensive, especially after rates fall. Ask the lender how it calculates them.
  • Rate lock: fixed rates can change between applying and settling. A rate lock, often costing a few hundred dollars, secures the rate for a set period.
  • The revert rate: when a fixed term ends, the loan usually rolls onto the lender’s standard variable rate, which may be well above its best offers. Put the date in your calendar.

Where rates might go next

The RBA lifted the cash rate by 0.25 points to 4.60% on September 29, 2026, its fourth increase this year, citing core inflation stuck at 3.6% and higher fuel prices. The September quarter inflation figures are due on October 28 and the next decision on November 3. Fixed rates already reflect what markets expect; if you fix, you are betting that rates will rise by more than the market expects, and if you stay variable, that they will rise by less. Nobody knows which, which is why many borrowers split. Before you take on any loan, check how much you can comfortably borrow with our borrowing power calculator.
