Variable rate

A variable interest rate fluctuates over the life of a loan in response to changes in central bank cash rates, wholesale funding costs, and lender pricing decisions. As the rate moves, scheduled repayments either rise or fall.

How variable rates work

Most variable home and personal loans reset their rate periodically — sometimes monthly, sometimes after each cash-rate decision. When the rate rises, the borrower’s repayment amount increases on the next billing cycle; when it falls, repayments shrink.

Example

A borrower with a $500,000 loan at 6% pays approximately $3,000 per month. If the rate rises by 0.5% to 6.5%, the monthly repayment increases by roughly $160. A 1% drop produces a similar reduction in the opposite direction.

Trade-offs

• Flexibility — variable loans typically allow unlimited extra repayments, redraw, and offset accounts
• Rate exposure — repayments rise with the market, requiring a budget buffer
• Lower headline costs in falling-rate environments — variable rates often start below equivalent fixed offers
• No break costs — borrowers can refinance or pay out the loan without penalty

Many borrowers split their loan between a fixed-rate portion and a variable portion to balance certainty with flexibility. Always assess affordability under a higher rate scenario, not just the current rate.
