The "Withdrawal Age" refers to the age at which individuals can begin to withdraw funds from their retirement accounts, such as 401(k) or IRA, without incurring penalties. For most retirement accounts in the United States, this age is set at 59½. Withdrawals made before reaching this age may be subject to a 10% early withdrawal penalty, in addition to regular income taxes. Reaching the withdrawal age allows individuals to access their savings for retirement expenses. It is important to plan withdrawals carefully to ensure that funds last throughout retirement, as withdrawing too early or too much can deplete savings quickly.
