The calculation and analysis of the results are as follows:

The bank's interest on credit card overdraft is generally calculated at five ten thousandths of a day, depending on the purpose and repayment.

If it is an overdraft, there will generally be an interest-free period. After the interest-free period, the daily interest shall be calculated at five ten thousandths. In case of cash withdrawal, the daily interest shall be calculated at five ten thousandths from the date of cash withdrawal.

Extended information Because each bank has its own policy, the annual interest is calculated from the first day of calculating the five-fifths interest, so it should be 50000*0.05%*365=9 125 yuan.

Generally, most banks have not paid off their debts, and interest is calculated according to the maximum overdraft. Only a few banks will automatically calculate the daily interest based on the paid amount and the actual unpaid amount.
