Estimates only · generic calculator

This is a generic financial calculator. It produces estimates only, based on the assumptions below and the figures you enter. It is general information — not personal or financial product advice— and does not take into account your objectives, financial situation or needs. Consider whether it's right for you and seek advice from a licensed professional before making any decision. MOMONEYMOFREE does not hold an Australian Financial Services Licence and does not recommend any specific financial product.

Assumptions used →
  • Principal & interest repayments on the balance you enter, over the remaining term you choose.
  • Assumes the full rate move passes through to your rate and that the balance and term stay the same.
  • Ignores offset/redraw balances, fees, fixed-rate periods and any repayment buffer you already pay.
  • Default loan size from ABS Lending Indicators (new owner-occupier); default rate is a typical variable rate — change both to your own numbers.
  • Calculated in your browser; nothing entered is stored.
