The overdraft interest of a credit card is five ten thousandths, which means that for every ten thousand yuan overdrawn, 5 yuan's interest needs to be paid every day. This interest calculation method is calculated according to the daily interest rate. The more overdraft, the more interest you need to pay.

Therefore, when using credit card to overdraw, you need to carefully consider your repayment ability to avoid excessive interest charges. In addition, different banks may have different overdraft interest policies, so you need to consult bank customer service for details.
