What a Certificate of Deposit Is

A certificate of deposit (CD) is an account at a bank or credit union where you deposit money for a fixed period — typically three months to five years — in exchange for a may provide interest rate. You agree not to withdraw the money until the term ends. In return, the bank pays you more interest than a regular savings account would.

The trade-off is simple: you lock up your money, and the bank locks in your rate. If you need the money before the term is up, you pay an early withdrawal penalty, usually a few months' worth of interest. If you leave the money untouched until maturity, you get back your original deposit plus all the interest earned.

CDs are one of the safest places to put money because they are insured by the Federal Deposit Insurance Corporation (FDIC) at banks or the National Credit Union Administration (NCUA) at credit unions — up to $250,000 per account per institution. That means even if the bank fails, your money is protected.

Key Takeaways

  • A CD locks your money away for a set time in exchange for a fixed interest rate that is usually higher than a savings account.
  • You pay a penalty if you withdraw before the term ends, typically equal to a few months of interest.
  • Your deposit is insured up to $250,000 by the FDIC or NCUA, making CDs one of the safest savings options.
  • CD rates vary by bank, term length, and current market conditions, so comparing offers before you deposit makes a real difference.
  • When a CD matures, you can withdraw the money, move it to a new CD, or let it roll over automatically at the bank's current rate.

How Interest Rates and Terms Work

The interest rate on a CD is set when you open the account and does not change for the entire term, no matter what happens in the broader economy. A three-month CD might pay 4.5 percent, while a five-year CD at the same bank might pay 5.2 percent. Generally, longer terms pay higher rates because the bank has your money for longer and can lend it out for longer periods.

The rate you see advertised is the annual percentage yield (APY), which accounts for how often interest is compounded — usually daily or monthly. This is the actual return you will earn if you hold the CD to maturity. When you compare CDs, always compare APY, not just the interest rate, because compounding makes a real difference over time.

Interest rates change constantly based on what the Federal Reserve does and what banks decide to offer. A CD opened today at 5 percent will still pay 5 percent when it matures in two years, even if rates have dropped to 3 percent by then. That is the benefit of locking in a rate — and also the risk, if rates rise and you are stuck in a lower-paying CD.

When to Use a CD Instead of a Savings Account

A CD makes sense if you have money you will not need for several months or years and you want a may provide return. Savings accounts pay interest too, but it is usually much lower — often under 1 percent — and it can change at any time. If you have $10,000 sitting in a savings account earning 0.5 percent, moving it to a one-year CD at 4.5 percent means earning roughly $400 more per year.

CDs also work well if you are trying to build discipline around saving. The penalty for early withdrawal discourages you from dipping into the money for everyday expenses. Some people use a CD ladder — opening multiple CDs with different maturity dates — so that money becomes available at regular intervals without locking everything away for years.

A CD is not the right choice if you might need the money soon. The early withdrawal penalty can wipe out months of interest, leaving you worse off than if you had kept the money in a savings account. CDs also do not keep pace with inflation over very long terms, so the purchasing power of your money may decline even though the dollar amount grows.

Early Withdrawal Penalties and What Happens at Maturity

If you withdraw money before the CD term ends, the bank charges a penalty. This penalty varies widely — some banks charge three months of interest, others charge six months, and a few charge a flat dollar amount. Before you open a CD, read the disclosure document to see exactly what the penalty is. A CD with a low rate and a high penalty might be worse than a savings account if you think there is any chance you will need the money early.

When the CD reaches its maturity date, the bank notifies you (usually by mail or email) and gives you a window — typically seven to ten days — to decide what to do. You can withdraw the money and the interest, move it to a new CD, or move it to another account at the bank. If you do nothing, many banks automatically roll the CD over into a new term at whatever rate they are currently offering. That new rate might be higher or lower than what you were earning.

To avoid surprises, mark your maturity date on your calendar and decide in advance whether you want to roll over or withdraw. If you want to move the money to a different bank or CD with a better rate, do it before the rollover happens. Some banks make it easy to shop around and move money; others make it deliberately inconvenient.

How to Compare CD Offers

CD rates and terms vary significantly between banks and credit unions. A large national bank might offer 4.0 percent on a one-year CD, while an online bank or credit union might offer 4.8 percent on the same term. Over one year, that 0.8 percent difference means real money — roughly $80 per $10,000 deposited.

When comparing, look at three things: the APY (not just the interest rate), the term length, and the early withdrawal penalty. Write down the APY and penalty for each option so you can see them side by side. Also check whether the bank or credit union is FDIC or NCUA insured — this is not optional if you want your money protected.

Online banks and credit unions often pay higher rates than brick-and-mortar banks because they have lower overhead costs. However, you will not be able to walk into a branch to ask questions or deposit cash. If you are comfortable managing money online, online banks are usually worth the higher rate. If you need in-person service, you may accept a lower rate in exchange for that convenience.

Tax Implications and Reporting

The interest you earn on a CD is taxable income. The bank will send you a Form 1099-INT at the end of the year showing how much interest you earned. You report this on your tax return, and you owe federal income tax on it (and state income tax in most states). This is true even if you did not withdraw the money — the interest is taxable in the year it is earned, not when you withdraw it.

If you earn more than $10 in interest from all sources combined, the bank must send you a 1099-INT. Keep this form with your tax records. If you earn less than $10, the bank may not send a form, but you still owe tax on the interest and should report it.

Some people use CDs in tax-advantaged retirement accounts like IRAs or 401(k)s, where the interest is not taxed until you withdraw money from the account. This can be a smart strategy if you have money in those accounts and want a safe, may provide return.

CD Alternatives and When They Make Sense

If a CD does not fit your situation, other options exist. A high-yield savings account pays interest that is usually close to CD rates but lets you withdraw money anytime without penalty. The trade-off is that the rate can change at any time, so you do not have the certainty a CD offers. A money market account is similar to a savings account but typically pays slightly higher interest and may come with a debit card or checkbook.

Treasury bills and Treasury notes, issued by the U.S. government, are also very safe and often pay competitive rates. They work differently from CDs — you buy them at a discount and receive the full face value at maturity — but the concept is similar: you lock up money for a set time and get a may provide return.

If you need your money to be completely accessible, a regular savings account is the safest choice, even though it pays less. The interest rate does not matter if you need to withdraw the money and face a penalty that erases your gains.

Frequently Asked Questions

Can I withdraw money from a CD before it matures?

Yes, but you will pay an early withdrawal penalty set by the bank. This penalty is usually several months of interest. Before you open a CD, ask what the penalty is and whether it is worth the risk if you think you might need the money sooner than planned.

What happens if the bank fails?

Your CD is insured up to $250,000 by the FDIC (at banks) or NCUA (at credit unions). If the bank fails, the insurance agency pays you your deposit plus any interest earned up to the maturity date. This protection is automatic — you do not need to do anything.

Is a CD better than a savings account?

A CD usually pays more interest, but only if you can leave the money untouched for the entire term. If you might need the money within a few months, a savings account is safer because you can withdraw without penalty. Compare the CD rate to the savings account rate at the same bank to see if the extra interest is worth giving up access.

Can I open a CD with a very short term?

Yes. Some banks offer CDs with terms as short as one month or three months. These typically pay lower rates than longer-term CDs, but they give you flexibility if you want to move money around frequently or are waiting to see if rates will rise.

What should I do when my CD matures?

You have several options: withdraw the money, open a new CD at the same bank, move the money to a different bank with a better rate, or move it to a savings account. Do not let it roll over automatically unless you have checked the new rate the bank is offering — it may be lower than what you were earning.
