If you use China Merchants Bank credit card to withdraw cash, you need to pay off the withdrawal amount and interest before the repayment date. The repayment date is generally fixed. You can log in to China Merchants Bank Credit Card APP or online banking to check the specific time of repayment date.

In addition, if you want to successfully apply for credit card withdrawal, you should also pay attention to the following points:

1. Make sure your bills and repayment records are good. If you have overdue records online, or have loan records of multiple platforms, it may attract the attention of big data risk control, resulting in the inability to apply for credit card withdrawal. You can use Xiaoqi Credit Information to get your big data and credit status, and see if there are any abnormal records.

2. Always pay attention to the credit card bill balance, and ensure that the bill balance, cash withdrawal amount and interest are paid off before the repayment date. If it is overdue, there will be high penalty interest and late payment fee, which will seriously affect your credit history.

3. Need to clarify the handling fee and interest of cash withdrawal. General banks will charge a certain fee and interest. Before using a credit card to withdraw cash, you need to carefully understand the fees and interest rates, and pay them off at the time of repayment, so as not to affect your credit history.
