Common questions
Should I always pick the lower headline rate?
Not necessarily. Fixed rates lock predictability for a defined period but may be revised on revert. Variable rates fluctuate; a +2% stress scenario can move repayments far above headline projections. Compare both on dollars at risk, not just headline.
What happens after the fixed period ends?
Most fixed loans revert to a variable rate set by the lender. Some allow re-fixing at then-current market rates. The revert rate often differs from the lender's advertised variable rate, so check the product disclosure.
Can I make extra repayments on a fixed loan?
Most fixed-rate products cap extra payments per year (often $10,000–$30,000). Pay above the cap and break costs may apply. Variable loans typically allow unlimited extra repayments.
