A "-"sign in the balance indicates that the current balance has a balance; There is no "-"sign in the balance, indicating that the current balance is overdrawn.
Credit card available limit: available limit refers to the unused credit limit of your credit card, that is, the amount you can overdraw. The calculation method is: credit line-unrecorded amount-accumulated used unrecorded amount = available amount.
For example, if the balance is 972 yuan and the available line is 300 yuan, it means that the current debt is 972 yuan and the available line is 300 yuan, so you can overdraw 300 yuan.
The difference between the two is that the balance is the amount of current bill repayment, that is, the amount that needs to be repaid. The available amount is the number of your credit limit MINUS the consumption limit, which is the available amount.
