A CD is a bank account where you lock up money for a set time in exchange for a higher interest rate

A certificate of deposit (CD) is a savings product offered by banks and credit unions. You give the bank a lump sum of money, agree not to touch it for a specific period—usually three months to five years—and in return the bank pays you a fixed interest rate that is higher than what you would earn in a regular savings account.

The trade-off is straightforward: the bank knows exactly when it can use your money, so it rewards you for that certainty. If you need the money before the CD matures (reaches the end of its term), you will pay an early withdrawal penalty, which is typically a few months' worth of interest. You do not lose your principal unless the penalty is very large, but you lose the benefit of the higher rate.

CDs are insured by the Federal Deposit Insurance Corporation (FDIC) up to $250,000 per account holder per bank, the same as regular savings accounts. This means your money is protected even if the bank fails.

Key Takeaways

  • A CD locks your money away for a set term—three months to five years is typical—in exchange for a may provide interest rate higher than a savings account.
  • You pay an early withdrawal penalty if you need the money before the CD matures, usually equal to a few months of interest.
  • CD rates are fixed when you open the account and do not change, even if the bank raises or lowers rates later.
  • CDs are FDIC insured up to $250,000, so your principal is protected if the bank fails.
  • The longer the term, the higher the rate—a five-year CD will pay more than a three-month CD at the same bank.

How CD interest rates and terms work

When you open a CD, the bank tells you the annual percentage yield (APY) you will earn and the exact maturity date. That rate is locked in and does not change for the life of the CD, even if the bank raises rates for new customers the next week. This is different from a savings account, where the rate can move up or down at any time.

The term length and the rate are connected. A three-month CD might pay 4.5 percent APY, while a five-year CD at the same bank might pay 5.2 percent. Banks offer higher rates for longer terms because they want to keep your money longer. The trade-off is that you give up access to it.

Interest is usually compounded daily and paid into the CD account itself, so it earns interest on top of interest. When the CD matures, you can withdraw the full amount (principal plus all interest), open a new CD with the same bank, or move the money elsewhere.

What happens when a CD matures

On the maturity date, your CD stops earning interest. Most banks give you a grace period—usually seven to ten days—during which you can withdraw the money without penalty or roll it into a new CD at the current rate.

If you do nothing during the grace period, many banks will automatically renew your CD into a new one with the same term at whatever rate they are offering at that moment. This can work in your favor if rates have gone up, but it locks your money away again. Read the renewal terms when you open the CD so you know what will happen.

Some banks send a notice before maturity; others do not. It is your responsibility to check your account or contact the bank if you want to do something other than renew. Mark the maturity date on your calendar or set a phone reminder.

Early withdrawal penalties and when they explore

If you withdraw money from a CD before it matures, you will pay a penalty. The amount varies by bank and by term length. A typical penalty for a one-year CD might be three months of interest; for a five-year CD, it might be six months or a year. Some banks charge a flat dollar amount instead.

The penalty is deducted from your interest earnings first. If you have earned $500 in interest and the penalty is $300, you keep $200 of the interest and your principal stays intact. If the penalty exceeds your interest, it comes out of your principal, so you get back less than you put in.

A few banks offer no-penalty CDs that let you withdraw without a penalty, but they pay lower rates in exchange. These are worth considering if you think you might need the money but want a rate better than a savings account.

CD laddering and how to manage multiple CDs

Some people open several CDs with different maturity dates so that money becomes available at regular intervals without paying penalties. This is called CD laddering. For example, you might open five one-year CDs, each maturing in a different year. Each year, one CD matures and you can withdraw or reinvest without touching the others.

Laddering works best when you have a larger sum to divide and you want to lock in current rates while keeping some flexibility. It also protects you if rates drop—you are not forced to reinvest everything at once into a lower-rate environment.

You can ladder CDs at the same bank or spread them across different banks to stay within FDIC insurance limits. Each bank insures up to $250,000 per account holder, so if you have $500,000 to invest, you would need two banks to be fully covered.

CDs versus savings accounts and money market accounts

A regular savings account has no term and no penalty for withdrawal, but the interest rate is lower and can change at any time. You have complete access to your money, which is valuable if you need it for an emergency. A CD pays more but locks the money away.

A money market account sits between the two. It usually pays more than a savings account but less than a CD, and it gives you limited check-writing or withdrawal privileges without penalty. Some people use money market accounts for money they might need within a year or two, and CDs for longer-term savings.

The right choice depends on when you will need the money. If you have an emergency fund, keep it in a savings account. If you have money you will not touch for at least a year, a CD will earn you more. If you are unsure, a money market account or a short-term CD (three to six months) splits the difference.

Where to open a CD and how to compare rates

Banks, credit unions, and online banks all offer CDs. Online banks typically pay higher rates because they have lower overhead costs. You can compare rates on sites like Bankrate, DepositAccounts, or the FDIC's own rate search tool, though you will need to visit each bank's website to open an account.

When comparing, look at the APY (not just the interest rate), the term length, the early withdrawal penalty, and the renewal terms. A bank offering 5.0 percent APY with a one-year penalty is not the same as one offering 5.1 percent with a six-month penalty. Calculate what the penalty would cost you if you had to withdraw early.

Make sure the bank or credit union is FDIC or NCUA insured. This information is on their website and in their disclosures. If it is not, your money is not protected if the institution fails.

Frequently Asked Questions

Can I withdraw money from a CD before it matures?

Yes, but you will pay an early withdrawal penalty. The penalty is usually a few months of interest, though it varies by bank and term length. If the penalty exceeds your interest earnings, it comes out of your principal, so you may get back less than you deposited.

What happens if I do not withdraw my money when the CD matures?

Most banks automatically renew your CD into a new one at the current rate during a grace period of seven to ten days. If you do not want this, contact the bank before maturity to withdraw or move the money. Check your account or set a reminder so you do not miss the important date.

Is my money safe in a CD if the bank fails?

Yes. CDs are FDIC insured up to $250,000 per account holder per bank, the same as savings accounts. If the bank fails, the FDIC will return your principal and accrued interest up to the limit. You do not lose money because of a bank failure.

Do I pay taxes on CD interest?

Yes. CD interest is taxable income in the year it is earned, even if you do not withdraw it. The bank will send you a 1099-INT form at tax time showing how much interest you earned. This applies whether the CD is in a regular account or a retirement account like an IRA.

What is the difference between a CD and a savings account?

A savings account has no term and no withdrawal penalty, but pays a lower interest rate that can change anytime. A CD locks your money for a set period and pays a higher fixed rate, but charges a penalty if you withdraw early. Choose a savings account for emergency funds and a CD for money you will not need for at least a year.
