According to the query on the official website of the Industrial and Commercial Bank of China:

1. The calculation method of ICBC’s credit card interest is as follows: 1,000 yuan * 0.05% * 47 days (August 15 to September 30 day) = 23.5 yuan.

2. The calculation method of liquidated damages is as follows: 100 yuan * 5% = 5 yuan. If the cardholder partially repays the loan before September 25 (inclusive) (repayment on September 25 is RMB 100) , because you only repay the minimum repayment amount of the September bill before the due payment date, you can enjoy the minimum repayment amount treatment of our bank, without paying liquidated damages, and your credit score will not be affected.

3. The cardholder must repay the principal and interest shown on the bill on October 1. The calculation formula is as follows: If the product applies interest calculation method 1, the cardholder must repay the principal of 1,000 yuan and interest of 23.2 Yuan.

4. The interest is calculated as follows: 1,000 yuan*0.05%*41 days (August 15-September 24) + (1,000 yuan-100 yuan)*0.05%*6 days (September 25 to September 30). If the product applies interest calculation method 2, the cardholder must repay the principal of 1,000 yuan and the interest of 21.15 yuan. The interest is calculated as follows: (1,000 yuan-100 yuan) * 0.05% * 47 days (August 15-September 30) .
