A CD is a savings account where you agree to leave money untouched for a set time in exchange for a higher interest rate

CD stands for certificate of deposit. When you open a CD at a bank or credit union, you hand over a lump sum of money — say $5,000 — and the bank agrees to pay you a fixed interest rate if you leave that money alone until a specific date. That date is called the maturity date. On that day, you get your original money back plus the interest the bank paid you.

The catch is that if you take the money out before the maturity date, the bank charges you a early withdrawal penalty. The penalty amount varies by bank and by how long the CD term is. A typical penalty might be three months' worth of interest, but it can be more or less depending on the institution and the CD's length.

Banks offer CDs because they want to know your money will stay put. That certainty lets them lend that money out to other customers at a profit. In return, they pay you more interest than you would earn in a regular savings account, where you can withdraw money anytime without penalty.

Key Takeaways

  • A CD locks your money in place for a set period — typically three months to five years — in exchange for a may provide interest rate higher than a regular savings account.
  • You receive your original deposit plus accrued interest when the CD reaches its maturity date, with no further action needed from you.
  • Withdrawing money before the maturity date triggers an early withdrawal penalty, usually equal to several months of interest.
  • CDs are FDIC-insured at most banks up to $250,000 per account, meaning your money is protected even if the bank fails.

How CD terms and interest rates work

When you open a CD, you choose how long to lock your money away. Common terms are three months, six months, one year, two years, three years, and five years. The longer the term, the higher the interest rate the bank usually offers you. A one-year CD might pay 4.5 percent annual interest, while a five-year CD at the same bank might pay 5.2 percent.

The interest rate on a CD is fixed, meaning it does not change. If you lock in 4.5 percent for one year, you will earn exactly 4.5 percent no matter what happens to interest rates in the economy during that year. This is different from a savings account, where the bank can lower the rate whenever it wants.

Interest on a CD is usually compounded — meaning the bank adds interest to your balance, and then pays interest on that new, larger balance. How often the bank compounds (daily, monthly, or quarterly) affects how much total interest you earn. A CD that compounds daily will earn slightly more than one that compounds monthly, all else equal.

What happens when your CD reaches maturity

When the maturity date arrives, your CD automatically matures. The bank deposits your original money plus all the interest into your account — usually a linked checking or savings account you named when you opened the CD. You do not have to do anything; the transfer happens on its own.

At that point, you have a choice. You can withdraw the money and use it however you want. You can open a new CD with the same bank or a different one. Or you can let the money sit in your regular savings account and decide later. Some banks have a grace period — usually seven to ten days after maturity — during which you can withdraw the money without penalty. After the grace period ends, if you do not withdraw or move the money, many banks automatically roll it into a new CD with the same term and the current interest rate.

Read the fine print when you open a CD to understand your bank's maturity and rollover rules. Some banks make it easy to opt out of automatic renewal; others make it harder.

Early withdrawal penalties and when they apply

If you need your money before the maturity date, the bank will let you take it — but you will pay a penalty. The penalty is deducted from your interest earnings or from your principal, depending on the bank and how much you are withdrawing.

Penalty amounts vary widely. A three-month CD might have a penalty of one month's interest. A five-year CD might have a penalty of six months' interest or even a full year's interest. Some banks calculate the penalty as a percentage of the deposit itself rather than as months of interest. Before you open a CD, ask the bank what the early withdrawal penalty is and get it in writing.

There are rare exceptions. Some banks waive the early withdrawal penalty if you are withdrawing because of a death in the family, a serious illness, or a court order. These exceptions are not standard, so ask your bank whether it offers any.

Why someone might choose a CD over a regular savings account

A CD pays more interest than a savings account because you are giving up the ability to access your money whenever you want. If you have money you know you will not need for the next two years, a two-year CD will earn you more than leaving that money in savings. Over time, that extra interest adds up.

A CD also works well if you want to lock in a good interest rate. If rates are high right now and you think they might drop, opening a CD lets you keep that rate for the entire term, no matter what happens in the economy.

CDs are also useful for people who worry they will spend money if it is too easy to access. Because withdrawing early costs you money, a CD creates a built-in barrier to impulse spending.

FDIC insurance and what it protects

Most CDs at banks are covered by FDIC insurance (Federal Deposit Insurance Corporation). This means if the bank fails and closes, the government will pay you back up to $250,000 per account. CDs at credit unions are covered by a similar program called NCUA insurance (National Credit Union Administration), also up to $250,000.

The $250,000 limit applies per depositor, per bank, per account type. If you have a CD and a savings account at the same bank, they are counted separately for insurance purposes, so you could have up to $250,000 in each and both would be fully covered. If you have two CDs at the same bank, they are added together and the total is covered up to $250,000.

FDIC and NCUA insurance do not protect you from early withdrawal penalties. If you withdraw before maturity and pay a penalty, that is your loss, not the bank's responsibility.

CD laddering and other strategies

Some people use a strategy called CD laddering to balance the higher interest rates of longer-term CDs with the flexibility of shorter terms. Here is how it works: instead of putting all your money into one five-year CD, you split it into five one-year CDs. Each year, one CD matures and you can either withdraw the money or open a new five-year CD. This way, you always have access to some of your money every year, but you also lock in longer-term rates on the rest.

Another approach is to open CDs with different maturity dates at the same time. You might open one three-month CD, one six-month CD, one one-year CD, and one two-year CD. As each one matures, you can reassess interest rates and decide what to do next. This spreads out your access to money and lets you respond to changing rates without locking everything away for years.

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 several months of interest, though it varies by bank and CD term. Some banks may waive the penalty in rare circumstances like death or court order, so ask your bank about its specific policy.

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

A savings account lets you withdraw money anytime without penalty, but pays lower interest. A CD locks your money for a set term and pays higher interest, but charges a penalty if you withdraw early. Both are FDIC-insured up to $250,000.

Do I have to pay taxes on CD interest?

Yes. CD interest is taxable income. The bank will send you a 1099-INT form at the end of the year showing how much interest you earned, and you must report it on your tax return. This is true even if you did not withdraw the money.

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

Most banks automatically roll your CD into a new one with the same term and the current interest rate. However, you usually have a grace period of seven to ten days to withdraw the money without penalty. Check your bank's policy so you know what will happen.

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

Yes, as long as your CD is at an FDIC-insured bank or NCUA-insured credit union. The government will pay you back up to $250,000 if the institution fails. You can verify FDIC or NCUA coverage on the bank's website or by calling the institution directly.
