Credit cards generally have interest in the following two situations:

Cash withdrawal: Cash withdrawal does not enjoy the interest-free period. Interest is charged at 0.05 per day from the day of withdrawal, and is charged on a monthly compound interest basis. China Merchants Bank's credit card charging standards charge a certain amount of cash advance handling fee.

If the credit card bill is not repaid in full and on time: If the total repayment amount of the current bill is not paid before the final payment date, all consumption in the month will not be interest-free, and the interest will be calculated based on each item in the bill. Interest is calculated on a transaction-by-transaction basis. Generally, interest is calculated at 0.05 per day from the second day of swiping the card until the transaction is repaid.
