Your balance after pending is the amount you currently have available to spend, taking into account the amount of money in your account and any recent transactions not yet cleared. This amount will not include any arranged overdraft limit you have. Various circ*mstances may cause a difference between your balance and balance after pending. These are explained below:
Recent debit card purchases
Your balance after pending shows recent debit card payments before we have fully processed (cleared) the payments. This means we have set aside from your account the money recently spent on your card before the seller actually takes it. When the money leaves your account, your balance will be reduced, but your balance after pending will stay the same, as we have already adjusted it to show the payments.
