Credit card interest is generally calculated at five ten thousandths of a day. To withdraw cash from a credit card overdraft, one has to pay a handling fee and the other has to pay interest, which is also calculated at five ten thousandths of a day.

The credit card is overdrawn by 50,000 yuan, and one month's interest is 750 yuan. However, credit card interest is affected by repayment time, overdue situation and other factors, so it is necessary to repay the actual interest according to the actual situation.
