China Bank has a credit card overdraft of 1, yuan, and the monthly interest is 15 yuan.

calculation process: overdraft interest = 1, yuan ×3 days× .5 = 15 yuan

For credit card overdraft consumer transactions, our bank generally provides an interest-free repayment period of 2-5 days. If you repay in full before the interest-free repayment period, overdraft interest will not be charged.

if you don't repay in full before the interest-free repayment period, you won't enjoy the interest-free repayment period, and the overdraft interest will be calculated based on the actual amount owed and the actual number of days owed from the transaction bookkeeping date. The overdraft interest rate is .5 ‰ of the daily interest rate, with compound interest on a monthly basis.

Time limit and calculation of credit card overdraft:

The maximum overdraft period of a credit card is 6 days.

credit card overdraft interest shall be calculated at the rate of five ten thousandths of daily interest within 15 days from the date of signing or the date of bank account entry (inclusive), and at the rate of ten thousandths of daily interest after 15 days, and at the rate of fifteen thousandths of daily interest after 3 days or when the overdraft amount exceeds the prescribed limit. The overdraft interest is not divided into sections, and the interest is calculated according to the highest interest rate grade of the deadline or the highest overdraft amount.

if the consumer overdraws in full and fails to repay the loan on time, it will incur overdraft interest and other expenses, which will lead to the amount of debt exceeding the limit. Because the overrun is caused by the cost of the credit card itself, some banks do not charge extra fees for this situation. For example, the credit card centers of CCB and China Merchants Bank now say that there is no provision for the overrun fee.

However, ICBC and CITIC Bank Credit Card Center said that if the amount owed exceeds the credit card limit, 5% of the overrun fee will be charged. However, ICBC said that it will only be charged once in an overrun period, while CITIC Bank said that the overrun fee will be compounded monthly.

if the cardholder uses the company card for overdraft, the company shall be responsible for the repayment of the overdraft amount and the payment of overdraft interest. If the cardholder overdraws by using the supplementary card of the personal card, the cardholder of the main card shall bear the responsibility of repaying the overdraft amount and paying the overdraft interest; If the cardholder of the main card loses the ability to repay, the cardholder of its subsidiary card shall bear the responsibility of repaying the overdraft amount and paying the overdraft interest.
