There are differences between the two in definitions, amounts, and display methods.

1. The difference between definition and limit: The available balance refers to the amount that can be used freely at present, excluding unfinished business or restricted amounts; while the account balance is the actual amount on the account, including The amount currently available and the amount currently unavailable.

2. Differences in display methods: In different types of accounts or financial instruments, the display methods of available balance and account balance may be different. For example, in a credit card or bank card, the account balance usually refers to the total amount owed on the account, while the available balance refers to the credit limit or cash withdrawal limit currently available on the credit card or bank card.
