Choose the lowest repayment, and the interest will be calculated on a per-brush basis. If February 18 consumes 100, February 12 consumes 50, and1October 28th consumes 5000+ 15 (minimum repayment amount), it will be regarded as 10. After each brush, the interest will be calculated from the bookkeeping date.

Extended data:

Minimum repayment amount: If the cardholder has difficulty in repaying all the payables before the due repayment date (inclusive), he can make repayment according to the minimum repayment amount stipulated by the issuing bank without affecting the credit status of the customer, but he cannot enjoy the interest-free repayment period. The minimum repayment amount is 10% of consumption and withdrawal amount plus other payables. The minimum repayment amount is listed on the current bill.

Calculation formula: minimum repayment amount = 10% general consumption balance+10% cash withdrawal balance+interest balance+installment consumption balance+other payable expenses balance+unpaid part of the minimum repayment amount in the previous period.
