Both scenarios use the same interest rate. The extra-payment line falls faster because more principal is repaid each month. Hover over the chart, or tap it on a touch device, to compare balances.

Without extra payments With extra payments
An amortisation comparison chart showing the estimated loan balance over time with and without an extra monthly payment.
This calculator provides an estimate only and is not credit advice. It assumes a constant interest rate, monthly compounding, and that both the scheduled repayment and extra payment are made at the end of every month. Fees, rate changes, redraws, offsets and other loan features are not included. The final repayment may be lower than the regular monthly amount and results may differ due to lender rounding.
