The repayment shown for "this period" is pro-rated from your annual repayment total, so it will only exactly match a real statement if the days below equal one full repayment cycle (e.g. 30 to 31 days for monthly).

days

Most lenders charge interest daily and debit it monthly. Use 28 to 31 to match a statement period, or 365 for a full year.

Indicative only. Calculator results are estimates only and do not constitute financial advice. Interest is calculated on a simple daily basis (annual rate divided by 365, applied to the loan balance after offset, with no compounding within the period) and assumes the loan and offset balances stay constant for the days entered. The repayment shown is pro-rated from your annual repayment total and may not exactly match a real statement period. Actual interest charged may vary depending on your lender's calculation method, statement dates, leap years, and account terms.
