Hello, if you hold a China Merchants Bank credit card and fail to return the minimum repayment amount of the bill in time before the due repayment date, you will be charged a late fee and interest, and your personal credit will be affected. The overdue fine is 5% of the unpaid minimum amount, and the minimum amount is RMB 10 yuan or USD 1 yuan. Interest refers to the collection of all consumption in the current period from the bookkeeping date (usually the day after consumption), with a daily interest rate of five ten thousandths until you pay it off in full.
