A CD locks your money away for a set time in exchange for a may provide interest rate

A CD (certificate of deposit) is a savings product where you give a bank or credit union a lump sum of money and agree not to touch it for a fixed period—usually three months to five years. In return, the bank pays you a fixed interest rate that is almost always higher than what you'd earn in a regular savings account. When the time period ends, you get your original money back plus the interest you earned.

The trade-off is simple: you give up access to your cash for a while, and the bank rewards you for that by paying more interest. If you need the money before the time period ends, you can withdraw it, but you'll pay a early withdrawal penalty—usually a few months' worth of interest. That penalty exists because the bank has already committed your money to lending it out or investing it elsewhere.

CDs are insured by the FDIC (Federal Deposit Insurance Corporation) up to $250,000 per account, so your money is protected even if the bank fails. This makes them one of the safest places to put money that you don't plan to use soon.

Key Takeaways

  • A CD pays a fixed interest rate for keeping your money locked away for a set period, typically ranging from three months to five years.
  • The interest rate on a CD is higher than a regular savings account because you agree not to withdraw the money early.
  • If you withdraw money before the CD matures, you pay an early withdrawal penalty that reduces your earnings.
  • CDs are FDIC-insured up to $250,000, making them a safe place to store money you won't need immediately.
  • The longer the CD term, the higher the interest rate is usually—but rates vary by bank and change over time.

How the interest rate works on a CD

When you open a CD, the bank tells you the exact interest rate you'll earn for the entire term. That rate does not change, no matter what happens to interest rates in the broader economy. If you lock in a 4.5% rate on a one-year CD, you earn 4.5% for the full year, even if rates drop to 2% next month.

The interest is usually compounded daily or monthly, which means you earn interest on your interest. A bank will show you the APY (annual percentage yield), which is the total return you'll actually receive after compounding is factored in. The APY is always slightly higher than the stated interest rate because of compounding.

Interest rates on CDs vary by bank and by how long the term is. Generally, longer terms pay higher rates because you're locking your money away for a longer time. A three-month CD might pay 4%, while a five-year CD from the same bank might pay 5%. Rates also change over time based on what the Federal Reserve does with its benchmark interest rate.

The difference between a CD and a savings account

A savings account lets you deposit and withdraw money whenever you want, with no penalty. A CD requires you to leave the money untouched for a specific period. Because of that restriction, banks pay more interest on CDs.

A savings account is better if you need quick access to your money or if you're still building an emergency fund. A CD is better if you have money you know you won't need for several months or years and you want to earn more interest than a savings account offers.

Some banks offer a hybrid called a money market account, which pays interest rates between savings accounts and CDs but lets you write checks or make withdrawals (though usually with limits). It's a middle ground if you want slightly higher interest but need more flexibility than a CD provides.

What happens when a CD reaches its maturity date

When your CD term ends, the bank sends you a notice telling you what happens next. You have a window of time—usually 7 to 10 days—to decide what to do with the money. You can withdraw it, move it to another account, or let it roll over into a new CD at the bank's current rate.

If you do nothing during that window, most banks automatically roll the money into a new CD with the same term at whatever rate they're currently offering. This can work in your favor if rates have gone up, but it can work against you if rates have dropped. Read the maturity notice carefully so you know what the new rate will be.

Many people set a calendar reminder for a few days before the maturity date so they can decide whether to roll over, withdraw, or move the money somewhere else. If you want to shop around for a better rate at a different bank, the maturity date is the time to do it without paying a penalty.

Early withdrawal penalties and when they apply

If you need your money before the CD matures, you can get it—but the bank will charge you an early withdrawal penalty. The penalty is usually expressed as a number of months of interest. A common penalty might be three months of interest, which means you lose three months' worth of earnings.

The penalty amount varies by bank and by the CD term. Longer-term CDs usually have larger penalties because you're breaking a longer commitment. A three-month CD might have a penalty of one month of interest, while a five-year CD might have a penalty of six months of interest.

Before you open a CD, ask the bank what the early withdrawal penalty is. If there's a chance you might need the money, factor that penalty into your decision. Sometimes the higher interest rate on a CD isn't worth it if you might have to pay a large penalty to access your cash.

Different types of CDs and when to use them

Most banks offer standard CDs with fixed terms and fixed rates. But some banks also offer specialty CDs that work differently. A no-penalty CD lets you withdraw your money early without paying a penalty, though the interest rate is usually lower than a standard CD. A bump-up CD lets you request a higher interest rate once during the term if rates go up. A step-up CD automatically increases your rate at set intervals.

A no-penalty CD makes sense if you want higher interest than a savings account but aren't sure you can leave the money alone for the full term. A bump-up or step-up CD is useful if you think interest rates might rise during your CD term and you want a chance to benefit from that without opening a new CD.

Some banks also offer CDs with very short terms—like one month or three months—which let you lock in a rate for a brief period. These are useful if you're waiting for rates to rise or if you want to test out a bank before committing to a longer term.

How to compare CDs across different banks

The most important number to compare is the APY, not the interest rate. APY tells you the actual return you'll receive after compounding, so it's the fairest way to compare one CD to another. A bank advertising a 4.5% rate might actually pay 4.59% APY depending on how often interest is compounded.

Also compare the early withdrawal penalty. A CD with a slightly lower rate but a much smaller penalty might be better if you think there's any chance you'll need the money early. And check whether the bank will automatically roll your CD over at maturity or if it will let you withdraw without penalty during the maturity window.

Online banks often pay higher rates than brick-and-mortar banks because they have lower overhead costs. If you're comfortable banking online and don't need in-person service, online banks are usually worth checking. The FDIC insurance is the same whether you bank online or in person.

Frequently Asked Questions

Can I withdraw money from a CD before it matures?

Yes, you can withdraw early, but you'll pay an early withdrawal penalty that reduces your earnings. The penalty is usually a set number of months of interest. Some banks offer no-penalty CDs that let you withdraw without a fee, though they pay lower interest rates.

What is the difference between APY and the interest rate on a CD?

The interest rate is the percentage the bank pays you. The APY (annual percentage yield) is the total return you actually receive after the bank compounds the interest. APY is always slightly higher and is the number you should use to compare CDs across banks.

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

Yes. CDs are insured by the FDIC up to $250,000 per account. If the bank fails, the FDIC will return your money plus any interest you've earned up to that limit. This makes CDs one of the safest places to put money.

What happens if I don't do anything when my CD matures?

Most banks automatically roll your CD into a new one with the same term at their current rate. You'll receive a notice before this happens with details about the new rate. If you want to avoid automatic rollover, you need to contact the bank during the maturity window and withdraw or transfer the money.

Do I have to pay taxes on CD interest?

Yes. CD interest is taxable income, and the bank will send you a 1099-INT form at the end of the year reporting how much interest you earned. You report this on your tax return. This is one reason some people prefer CDs for money they don't need to spend—the interest is locked in and predictable.
