Certificate of Deposit (CD) Definition and Meaning

A savings product where you lock your money away for a set period (anywhere from 3 months to 5+ years) in exchange for a guaranteed, usually higher interest rate than a regular savings account.

Think of a CD as a deal you make with your bank: you promise not to touch your money for a set amount of time, and they promise you a guaranteed interest rate that's typically better than what a savings account pays.

CD terms run anywhere from one month to 10 years, with 6-month to 5-year terms being the most popular. Longer terms usually mean higher rates, though that's not always the case—sometimes short-term CDs actually pay more (it depends on the interest rate environment). As of 2025, CD rates land roughly between 3.5% and 5%+ depending on the term and bank.

There's a catch, of course: if you pull your money out early, you'll pay a penalty—typically 90 days to a full year of interest, depending on how long the CD term is. Some banks do offer no-penalty CDs with slightly lower rates if you want an escape hatch.

A popular strategy is called CD laddering. Instead of dumping all your cash into one CD, you spread it across several with staggered maturity dates (say, 1-year, 2-year, 3-year, 4-year, and 5-year CDs). As each one matures, you roll it into a new 5-year CD. This way you get regular access to a portion of your money while still locking in those longer-term rates.

CDs are FDIC-insured up to $250,000, making them about as safe as it gets. They're a great fit for money you're confident you won't need during the term—things like a future down payment, a planned big purchase, or a conservative slice of your portfolio.

Frequently Asked Questions

▸Are CDs better than high-yield savings accounts?

It depends on your situation. CDs lock in your rate, which is great if rates are about to drop. High-yield savings accounts keep your money flexible but the rate can change anytime. If you definitely won't need the cash for the CD's full term, you might get a slightly better rate. If flexibility matters more, go with the savings account.

▸What happens when a CD matures?

You'll usually get a 7-10 day window to withdraw your money or pick a new CD term. If you don't do anything, most banks will automatically roll your money into a new CD at whatever rate they're offering—which could be higher or lower than what you had before.
