A Certificate of Deposit is a savings account where you lend money to a bank for a fixed period in exchange for a may provide interest rate

A Certificate of Deposit (CD) is a contract between you and a bank or credit union. You give them a sum of money — anywhere from $500 to $100,000 or more, depending on the institution — and agree to leave it untouched for a set period. In return, the bank pays you a fixed interest rate, usually higher than what a regular savings account offers. When the term ends, you get your original money back plus the interest earned.

The trade-off is simple: you give up access to your money for a defined time, and the bank rewards you for that commitment. The longer you agree to lock your money away, the higher the interest rate typically is. A 3-month CD pays less than a 12-month CD, which pays less than a 5-year CD.

CDs are insured by the Federal Deposit Insurance Corporation (FDIC) if held at a bank, or by the National Credit Union Administration (NCUA) if held at a credit union. That means if the institution fails, your money up to $250,000 is protected by the government.

Key Takeaways

  • You deposit a fixed amount of money for a set term — typically ranging from a few months to five years — and receive a may provide interest rate in return.
  • The interest rate is locked in when you open the CD and does not change, even if market rates rise or fall during your term.
  • Withdrawing money before the term ends usually costs you an early withdrawal penalty, which can eat into or eliminate your interest earnings.
  • CDs are FDIC or NCUA insured up to $250,000, making them one of the safest places to keep money in a bank or credit union.
  • CD rates vary by institution and term length, so comparing offers from different banks can mean hundreds of dollars in additional interest.

How the interest rate and term length work together

When you open a CD, the bank tells you the Annual Percentage Yield (APY) — the actual return you will earn over one year, accounting for how often interest is compounded. This rate is locked in for the entire term. If you open a 2-year CD at 4.5% APY, you will earn 4.5% per year for the full two years, regardless of whether market rates climb to 6% or drop to 2%.

Term lengths range from as short as one month to as long as ten years, though most banks offer terms between three months and five years. Longer terms almost always pay higher rates because the bank gets to use your money for a longer period. A one-year CD might pay 4.0% APY, while a five-year CD at the same bank might pay 4.8% APY. The difference compounds: $10,000 at 4.0% for five years grows to about $12,167, while $10,000 at 4.8% for five years grows to about $12,574.

Some banks offer bump-up CDs or step-up CDs, which let you increase your rate once or twice during the term if market rates rise. These typically pay slightly lower starting rates than standard CDs because you have the option to benefit from rate increases.

What happens if you need the money before the term ends

CDs penalize early withdrawal because the bank is counting on keeping your money for the full term. The penalty is usually stated as a number of months of interest. A CD with a three-month early withdrawal penalty means you lose three months' worth of interest if you cash out early. On a $10,000 CD earning 4.5% APY, that penalty is roughly $112.50.

If you withdraw before earning enough interest to cover the penalty, you will get back less than you deposited. For example, if you open a 5-year CD, withdraw after two months, and face a six-month penalty, you will lose money. This is why CDs work best for money you genuinely will not need during the term.

Some banks now offer no-penalty CDs, which let you withdraw your money without a penalty, though usually only after a short waiting period (often seven to ten days). These CDs pay lower rates than standard CDs because you have the flexibility the bank does not want to give you.

CD laddering: a strategy for accessing money regularly

If you have a larger sum to invest but want some money available each year, you can use a strategy called CD laddering. You divide your money into equal portions and open CDs with staggered maturity dates. For example, with $10,000, you might open five $2,000 CDs with terms of one, two, three, four, and five years. Each year, one CD matures and you can withdraw the money or roll it into a new five-year CD.

Laddering lets you take advantage of higher rates on longer-term CDs while keeping some money accessible every year. It also protects you if rates rise: when each CD matures, you can open a new one at the current market rate rather than being locked into an old rate for the full five years.

How CD rates compare to other savings options

CDs typically pay more than regular savings accounts or money market accounts at the same bank, but less than what you might earn from stocks or bonds over the long term. The trade-off is safety and certainty: you know exactly what you will earn, and your money is insured.

High-yield savings accounts, offered by online banks, sometimes pay rates competitive with or close to CD rates, and they offer more flexibility because you can withdraw money without penalty. However, savings account rates can change at any time, while CD rates are locked in. If rates fall, a CD protects you; if rates rise, a high-yield savings account lets you benefit immediately.

Treasury bills and bonds, issued by the U.S. government, also offer fixed rates and safety, but they work differently — you buy them at auction and can sell them before maturity on the secondary market, though the price may fluctuate. CDs are simpler: you deposit, wait, and collect your money plus interest.

Where to open a CD and what to compare

You can open a CD at any bank or credit union. Online banks typically offer higher rates than brick-and-mortar banks because they have lower overhead costs. Credit unions often offer competitive rates to their members. Before opening a CD, compare the APY, the term length, the early withdrawal penalty, and any minimum deposit requirement across at least three institutions.

A difference of 0.5% APY might seem small, but on a $25,000 CD for three years, it amounts to roughly $375 in additional interest. Websites that aggregate CD rates from multiple banks can help you see what is available, though you will need to contact the bank directly or visit their website to open the account.

Check whether the CD is FDIC or NCUA insured and confirm the insurance limit. If you are depositing more than $250,000, you can open multiple CDs at different institutions to stay within the insurance limit at each one.

Special CD types: brokered CDs and jumbo CDs

Brokered CDs are CDs sold through investment brokers rather than directly from a bank. They can offer higher rates and more flexible terms, but they are more complex. If you sell a brokered CD before maturity on the secondary market, you may receive more or less than you paid, depending on how interest rates have moved. Brokered CDs are still FDIC insured if held at an insured bank, but the insurance rules are different — you need to understand how your broker structures the account.

Jumbo CDs require a larger minimum deposit, often $100,000 or more, and typically pay higher rates to attract large deposits. If you have that much money to invest and want the safety of a CD, a jumbo CD can be worthwhile, but make sure you understand the early withdrawal penalty and the insurance coverage.

Frequently Asked Questions

Can I open multiple CDs at the same bank?

Yes. You can open as many CDs as you want at the same institution. Each CD is separately insured up to $250,000 by the FDIC or NCUA, so if you have $500,000 to invest, you could open two $250,000 CDs at the same bank and both would be fully protected.

What happens when my CD matures?

When the term ends, the bank notifies you and gives you a grace period — usually seven to ten days — to decide what to do. You can withdraw the money, open a new CD at the current rate, or move it to another account. If you do nothing, many banks automatically roll the CD into a new term at the current rate, though you can cancel this within the grace period.

Are CD interest earnings taxable?

Yes. Interest earned on a CD is taxable income in the year it is credited to your account, even if you do not withdraw the money. The bank will send you a 1099-INT form at tax time reporting the interest you earned. This is one reason CDs in retirement accounts like IRAs can be useful — the interest grows tax-deferred.

Is there a minimum deposit required for a CD?

Most banks require a minimum deposit to open a CD, typically between $500 and $2,500, though some online banks have lower minimums or none at all. A few banks offer CDs with no minimum, so if you have a small amount to invest, shopping around is worth your time.

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

A savings account lets you deposit and withdraw money whenever you want, but it pays a lower interest rate that can change at any time. A CD locks your money for a set term, pays a higher fixed rate, but charges a penalty if you withdraw early. Choose a CD if you have money you will not need for several months or longer; choose a savings account if you need flexibility.
