Hello, if you use China Merchants Bank's credit card, you used to repay on time normally. By default, our credit card has a 3-day grace period. If your payment arrives within 3 days after the final repayment date, it will not be overdue. I suggest you pay back on time in the future to avoid overdue.

If you mean how much interest there will be, then when you use revolving credit to repay loans or use cash in advance, revolving interest will be charged. If all the consumption funds are paid off in full before the due repayment date of the current billing cycle, you can enjoy the interest-free period by swiping your card without generating cyclic interest; If you don't pay off all the bills in the current period on time, it will be regarded as using revolving credit. From the bookkeeping date (usually the day after consumption), interest will be charged on all the consumption in the current period, with a daily interest rate of five ten thousandths, until you pay off all the bills. If you use the cash advance function, you cannot enjoy the interest-free period of cash advance. Interest will be calculated from the date of cash withdrawal, with a daily interest rate of 0.5 ‰, and compound interest will be calculated monthly until it is paid off.
