The current balance includes the total amount of money in your account at that particular time. If there are pending withdrawals or payments, the available balance is how much money will be left after the pending transactions are complete.
It’s best to plan your purchases or budget based on the available balance. If you make a purchase that exceeds your available balance, your account could overdraft when the pending transaction is applied to your account. If you use digital banking, you can view any pending transactions in your account transaction history.
