Generally speaking, credit card overdraft interest is calculated at the rate of five ten thousandths of daily interest from the date of signing the contract or the date of posting in the bank account (inclusive) 15 days, five ten thousandths of daily interest after 15 days, and fifteen thousandths of daily interest after 30 days or when the overdraft amount exceeds the specified limit. The overdraft interest is not divided into sections, and the interest is calculated according to the highest interest rate grade or the highest overdraft amount.

That is, the credit limit in the credit card is used up, but it is still being spent. This is called overdraft. The daily interest rate of credit card consumption is 0.05%, with the shortest interest-free period of 25 days and the longest interest-free period of 56 days; There is no interest-free period for withdrawal, and interest will start to accrue from the date of withdrawal, with a daily interest rate of 0.05% and a handling fee.
