Monthly — 12 repayments per year.
Fortnightly — 26 half-monthly repayments each year, equivalent to making one extra monthly repayment annually. This can reduce total interest and help repay your loan sooner.
Weekly — 52 quarter-monthly repayments each year, also equivalent to making one extra monthly repayment annually. This may reduce interest costs and shorten your loan term.

Weekly — 52 quarter-monthly repayments each year, also equivalent to making one extra monthly repayment annually. This may reduce interest costs and shorten your loan term.
Annual — Applies one repayment each year using the current loan settings.
One-Time — Applies a single lump-sum repayment once during the scenario and does not repeat.
Results are estimates and may vary depending on your lender's repayment policies.
Repayment Type
Interest-Only Period
Interest-only repayments reduce the required payment for the selected period, but the loan principal generally does not reduce during that time. Principal and interest repayments are then calculated over the remaining loan term, which can increase later repayments and total interest.
