Which term describes the action of taking money out of a bank account?

The action of taking money out of a bank account is referred to as "withdrawing." This term specifically denotes the process where an account holder removes funds from their account, either through an ATM, a bank teller, or online banking.

In a banking context, "withdrawing" is a standard term that clearly communicates the idea of accessing and taking out money already deposited in the account. The other terms do not convey the same meaning. "Investing" typically involves using money to purchase assets or securities with the expectation of generating a return over time, while "depositing" refers to adding money into a bank account. "Collecting" is a more general term that could apply to gathering or receiving items or money but does not specifically indicate the action of removing money from an account. Thus, "withdrawing" accurately captures the specific action described in the question.
