The calculation formula for credit card liquidated damages: repayment liquidated damages = (minimum repayment amount - amount repaid as of the due payment date) × 5%. Under normal circumstances, credit card default penalties are charged at 5% of the unpaid portion of the minimum repayment amount. Each bank has different standards for charging liquidated damages. Cardholders should refer to the card-issuing bank's standards for charging liquidated damages.

Credit card repayment penalty refers to when the cardholder fails to repay the credit card by the due date or the repayment amount is less than the minimum repayment amount. The minimum credit card default penalty is 1 US dollar or 1 euro or 5 yuan (the currency is the same as the corresponding minimum repayment amount, calculated on a monthly basis), or charged according to the agreed price if otherwise agreed in the agreement.

For example: The total repayment amount due to the cardholder's bill settlement on July 7 is 2,000 yuan, the minimum repayment amount is 200 yuan, and the due date of repayment is July 27. The cardholder paid back the credit card balance of 100 yuan on July 27. Since the cardholder failed to pay off the minimum payment amount before the due payment date, the bank will charge a penalty of 5 yuan in the August bill.

Cardholders can log in to personal online banking and mobile banking to check the specific credit card due date. Repaying the minimum payment can maintain a good credit history of the cardholder.

There is no additional repayment due date for credit card installment business, and the cardholder can repay the amount normally according to the credit card bill.
