The calculation method of credit card available limit is: available limit = credit limit approved by the bank-outstanding debt on the bill-transaction amount that has not been recorded but has occurred-other related interests and expenses.

Unpaid recorded amount refers to the amount of credit card transactions that have been booked but not returned; Cumulative used unrecorded amount refers to the amount of credit card transactions that have occurred but have not been accounted for; Other related interests and expenses refer to interest such as cash withdrawal or installment payment.

For example, if the credit line is 20,000 yuan, the outstanding amount is 654.38+0,000 yuan, and the used unrecorded amount is 4,000 yuan, the available line is 6,000 yuan.
