Calculator assumptions and important information

This calculator is a general educational model, not a prediction, quote, offer of credit or financial advice. It does not consider your objectives, financial situation or needs, and results should not be your only source of information when making a financial decision.

  • It models principal-and-interest loans only, with the interest rate remaining unchanged for the full term.
  • Interest is compounded at the selected repayment frequency. Many Australian lenders calculate interest daily and charge it monthly, so lender figures may differ.
  • Extra repayments are assumed to start immediately and continue at the same amount for every selected repayment period. Your lender may restrict extra repayments or charge break costs, particularly on fixed-rate loans.
  • Estimates exclude establishment, ongoing, package, discharge and government fees; offset and redraw arrangements; rate changes; repayment holidays; taxes; and lender-specific timing or rounding.
  • The calculator does not assess affordability or eligibility. Any loan remains subject to a lender's criteria, assessment and approval. Consider obtaining advice from a licensed professional if you need help.

Calculation assumptions are aligned with general guidance published by ASIC's Moneysmart for principal-and-interest mortgage calculators.
