Calculation method of credit card available line of Bank of Communications: credit line-unrecorded amount-used accumulated unrecorded amount = available line. For example, your credit line is 20,000 yuan, the unrecorded amount is 1000 yuan, and the used unrecorded amount is 4,000 yuan, so your available line at this time is 6,000 yuan. The available amount will decrease with each consumption, and will be restored accordingly with your repayment in each installment.

Note: The unrecorded amount refers to the amount that the credit card transaction has been accounted for, but you have not returned it; The accumulated amount used but not accounted for refers to the amount of credit card transactions that have occurred but not accounted for.

How many days is the validity period of the Bank of Communications credit card to increase the temporary limit?

The increased temporary credit line is generally valid within 30 days, and your credit line will be automatically restored to the original credit line after expiration.

After the temporary credit limit is increased, the part actually used exceeding the original credit limit will be added to the minimum repayment amount of the next statement. There is no extra charge for the overused part, but you can't enjoy the convenience of revolving credit. Please pay off in one lump sum on the due repayment date.
