A variable rate home loan has an interest rate that can move up or down over the life of the loan, typically in response to changes in the Reserve Bank of Australia (RBA) cash rate. Variable rates are the most common loan type in Australia and offer features that fixed rate loans often restrict.
How Variable Rate Loans Work
When you take out a variable rate home loan, your interest rate is set by your lender based on the RBA cash rate, their cost of funding, and competitive positioning. When the RBA raises or lowers the cash rate, lenders typically pass on some or all of the change to variable rate borrowers. This means your repayments can increase or decrease over time.
Advantages of Variable Rate Home Loans
- Offset account access — Most variable loans allow you to link a 100% offset account, reducing the interest you pay by the balance in your everyday account
- Unlimited extra repayments — Pay more when you can, with no penalties or limits
- Redraw facility — Access extra repayments you have made if you need funds later
- No break costs — Switch lenders or refinance at any time without paying break fees
- Benefit from rate cuts — When the RBA lowers rates, your repayments may decrease
Risks of Variable Rate Home Loans
- Rate increases — If the RBA raises rates, your repayments will rise, sometimes significantly
- Budget uncertainty — Monthly repayments can change, making long-term budgeting harder
- Lender discretion — Lenders can increase rates independently of the RBA
When to Choose a Variable Rate
Variable rate loans suit borrowers who value flexibility, want to make extra repayments, or plan to pay off their loan faster. They are particularly effective when combined with an offset account for investors and owner-occupiers who maintain healthy transaction account balances. If you are comfortable with some payment variability and want the freedom to refinance without penalties, a variable rate is likely the right choice.
Variable vs Fixed Rate Comparison
| Feature | Variable Rate | Fixed Rate |
|---|---|---|
| Offset account | Yes (100%) | Rare / partial |
| Extra repayments | Unlimited, no penalty | Often capped (e.g. $10k/year) |
| Break costs | None | Can be thousands of dollars |
| Rate certainty | No — rates can change | Yes — locked for the fixed term |
| Redraw | Yes | Sometimes restricted |
Split Your Loan — The Best of Both
Many borrowers choose a split loan, fixing a portion of their loan for certainty while keeping the rest variable for flexibility. For example, you might fix 60% at a competitive fixed rate and keep 40% variable with an offset account. Lagos Financial can model different split scenarios to find the right balance for your situation.
Frequently Asked Questions
What happens to my variable rate when the RBA changes rates?
Lenders typically adjust variable rates within days of an RBA decision, though they are not required to pass on the full change. Your lender will notify you of any rate adjustment and your new repayment amount.
Can I switch from variable to fixed?
Yes, most lenders allow you to fix all or part of your variable loan at any time. Your broker can compare the available fixed rates across multiple lenders to find the best option.
Is a variable rate better for investors?
Many investors prefer variable rates because of the 100% offset account (which helps manage cash flow across multiple properties) and the ability to make interest-only repayments for a period. The flexibility to refinance without break costs is also valuable as your portfolio grows.
