Under normal circumstances, the credit card penalty is 5% of the unpaid part of the minimum repayment amount, and the charging method is one-off. For example, suppose a user overdraws 654.38+00000 yuan with a credit card, and the minimum repayment date is 654.38+0000 yuan. Users will only pay back 300 yuan when it is due, and 700 yuan will be charged 5% penalty according to 35 yuan before it can be paid back.
