Credit card overdraft interest shall be charged at the rate of five ten thousandths of daily interest within 15 days from the signing date or the bank bookkeeping date (inclusive), and at the rate of five ten thousandths of daily interest after 15 days, and at the rate of fifteen thousandths of daily interest after 30 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 or the highest overdraft amount.

Take a credit card spending of 50,000 yuan as an example. If it takes 45 days from the billing date to the repayment date, the cardholder will repay 40,000 yuan on the repayment date, and the remaining 10000 yuan will not be repaid on time. If you hold a card of China Construction Bank or China Merchants Bank, you need to pay interest at the base of 50,000 yuan per day, and you need to pay overdraft interest within 45 days 1 125 yuan;

If you hold ICBC's credit card, you only need to calculate the overdraft interest for the unpaid 1 000 yuan, and the overdraft interest to be paid within 45 days is 225 yuan, a difference of 5 times. If you can't repay on time, it's not because you can't repay, but because you remember wrong, which leads to a small number of mistakes, then the difference is even greater.

Interpretation of some problems about the specific application of law in handling criminal cases that hinder credit card management

Article 6? If the cardholder overdraws beyond the prescribed limit or time limit for the purpose of illegal possession, and fails to return it for more than three months after being effectively collected by the issuing bank twice, it shall be deemed as "malicious overdraft" as stipulated in Article 196 of the Criminal Law.

The purpose of illegal possession should be judged according to the cardholder's credit history, repayment ability and willingness, the application and overdraft of credit cards, the use of overdraft funds, the performance after overdraft, and the reasons for not repaying according to regulations. It is not allowed to identify the purpose of illegal possession just because the cardholder fails to repay the loan according to the regulations.

In any of the following circumstances, it shall be deemed as "for the purpose of illegal possession" as stipulated in the second paragraph of Article 196 of the Criminal Law, unless there is evidence to prove that the cardholder does not have the purpose of illegal possession:

(a) knowing that there is no repayment ability and a large amount of overdraft can not be returned;

(2) After applying for a credit card with a false credit certificate, it is overdrawn and cannot be returned;

(3) Escaping after overdraft or changing contact information to avoid bank collection;

(4) evading or transferring funds, concealing property or evading repayment;

(five) the use of overdraft funds for criminal activities;

(six) other illegal possession of funds, refused to return.
