When your CD matures, you have options! You can withdraw the funds, reinvest in a new CD, or roll over the money. Consider your financial goals and needs before making a decision. If you need the money now, withdrawing it may be best. But if you can afford to keep your cash locked up for another term, rolling over might make sense. Your bank or credit union may automatically renew your CD, but review the terms to understand what happens next.
