How this tool works

Reviewed 6 September 2026. Monthly repayment estimate, reviewed 12 September 2026.

Calculation outline

  1. Compares normal repayments with paying extra regularly or as a one-off amount.
  2. Calculates cumulative interest savings and estimated whole months saved. Regular extras use their selected frequency, converted to monthly equivalents.

Worked example

Example: an extra $100 per fortnight reduces loan term and total interest compounding over time.

Limits

  • Fixed-rate loans may have restrictions or break fees on extra repayments exceeding lender annual caps (typically $10,000 to $20,000/yr).
