How this tool works
Reviewed 6 September 2026. Monthly repayment estimate, reviewed 12 September 2026.
Calculation outline
- Compares normal repayments with paying extra regularly or as a one-off amount.
- 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).
