How the estimates work
  • Principal-and-interest repayments use a standard monthly amortisation formula over your remaining loan term. Interest-only payments equal the balance multiplied by the annual rate, divided by 12.
  • Both comparisons use the same balance and remaining term to isolate the rate change. Offsets, redraw, fees, daily interest calculations and lender-specific rounding are excluded.
  • Weekly figures are the monthly difference × 12 ÷ 52. They are budgeting equivalents, not a weekly repayment schedule.
  • Annual figures are the monthly difference × 12, assuming the new payment applies for a full year. They are not actual costs incurred this calendar year.
  • Principal-and-interest differences are repayment changes, not additional interest expense alone. Interest-only estimates apply only during the interest-only period and exclude any later switch to principal-and-interest.
  • Your actual repayments depend on your lender and when any rate change takes effect. These are illustrative estimates, not a quote or a borrowing-capacity assessment.
  • Calculations use unrounded amounts. Displayed monthly and annual amounts may differ slightly when multiplied.

Monthly repayments: $6,222 before, $6,387 after. Monthly difference: +$164.
