Payment Frequency
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.
