When using CCB Long Card credit card to withdraw cash, you need to pay attention to the calculation of interest and handling fees. Different from the interest-free period for consumption, interest on cash withdrawals starts from the day of withdrawal, and the daily interest is 50,000% of the cash withdrawal amount. In addition, a 0.5 handling fee will be charged for each cash withdrawal, with a minimum of no less than 2 yuan. The daily cash withdrawal limit per card is 2,000 yuan, and the cumulative cash withdrawals cannot exceed half of the credit card limit. As a specific example, if the user withdraws 2,000 yuan in cash and repays it 10 days later, the total amount that needs to be repaid will include: principal of 2,000 yuan, handling fee of 2,000 yuan*0.5, and 10 days of interest (2,000 yuan*0.05* 10). Calculated in this way, the total cost for 10 days is 20 yuan, which is a considerable additional cost. Therefore, it is strongly recommended that cardholders try to avoid overdraft withdrawals or pay them off as soon as possible after withdrawal to avoid unnecessary financial burden.
