Variable Rate

Plain-English definition. A variable-rate home loan has an interest rate that can move up or down over the life of the loan — at the lender's discretion, typically influenced by RBA cash rate decisions and the lender's funding costs.

How it works in Australia. Variable rates are the default for the majority of Australian mortgages. Lenders typically reprice within 1–4 weeks of an RBA move, but they're not legally required to pass on cuts (or hikes) in full or at all. The standard variable rate (SVR) is the headline; most borrowers receive a discount of 1.5–2.5% off SVR via packages or negotiation. Variable loans usually permit unlimited extra repayments, free redraw, full offset, and refinance with no break costs (just a discharge fee of $250–$400). The RBA's Indicator Lending Rates tracks variable rates over time.

Concrete example. A $700,000 variable loan at 6.20% has monthly P&I repayment of $4,288. If the RBA cuts 0.25% and the lender passes it on, the new rate is 5.95% and repayment drops to $4,180 — a $108/month saving and roughly $39,000 of interest saved over 30 years if the rate stays there. Conversely a 0.25% hike adds $108/month.

Common confusion. Borrowers think "variable" means rates move automatically with the RBA. They don't — banks make independent commercial decisions on whether and how much to pass through. In 2023 several banks held back portions of RBA cuts to protect deposit margins. Always benchmark your rate against current published comparison tables.
