A Certificate of Deposit is a savings account where you lock up your money for a set time in exchange for a higher interest rate

A Certificate of Deposit (CD) is an agreement between you and a bank or credit union. You give them a lump sum of money — say $5,000 — and promise not to touch it for a specific period, called the term. In return, they pay you a fixed interest rate that is almost always higher than what a regular savings account offers. When the term ends, you get your original money back plus the interest you earned.

The bank uses your money during that time, which is why they pay you more than they would if you could withdraw whenever you wanted. You are trading access to your cash for a better interest rate. If you need the money before the term is up, you can usually withdraw it, but the bank will charge you a penalty — typically a few months' worth of interest.

CDs are one of the safest places to put money because they 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 bank fails, your money up to $250,000 is protected by the federal government.

Key Takeaways

  • You deposit a fixed amount of money and agree not to withdraw it for a set period — typically three months to five years — in exchange for a may provide interest rate.
  • The interest rate on a CD is higher than a regular savings account because the bank knows exactly how long they can use your money.
  • If you withdraw your money before the term ends, the bank charges an early withdrawal penalty, usually equal to a few months of interest.
  • Your CD is insured up to $250,000 by the FDIC (at banks) or NCUA (at credit unions), so your principal is protected even if the institution fails.
  • When your CD matures, you can cash it out, move the money to a new CD, or let it roll over into a new CD at the current rate.

How the interest rate and term length work together

The longer you agree to lock up your money, the higher the interest rate the bank will offer you. A three-month CD might pay 4.5 percent, while a five-year CD from the same bank might pay 5.2 percent. The bank is willing to pay more because they want to keep your money longer and avoid the risk that you will need it back soon.

The interest rate is fixed, meaning it does not change during the term. If you buy a one-year CD at 5 percent, you will earn 5 percent for the entire year, even if the bank raises or lowers its rates next month. This predictability is one reason people choose CDs — you know exactly how much money you will have when the term ends.

Interest rates vary by bank and by the current economic environment. You can compare rates across different banks and credit unions before you buy. Some online banks offer higher rates than brick-and-mortar banks because they have lower overhead costs.

What happens when your CD reaches maturity

When your term ends, your CD matures. At that point, you have several choices. You can withdraw the money and the interest you earned. You can open a new CD with the same bank or a different one. Or you can let the CD automatically roll over into a new CD at the bank's current rate — though you usually have a grace period of a few days to change your mind and withdraw instead.

The rollover option is convenient but not always the best choice. If interest rates have dropped since you opened your original CD, the new rate will be lower. If rates have risen, you might want to shop around and find a better rate elsewhere before rolling over. Read your CD agreement to see how many days you have to act after maturity.

Early withdrawal penalties and when they explore

If you need your money before the term ends, you can withdraw it, but you will pay a penalty. The penalty amount varies by bank and by how long the CD term is. A common penalty is three to six months of interest, though some banks charge a flat dollar amount or a percentage of your principal.

A few banks offer no-penalty CDs, which let you withdraw your money without a fee before maturity. The trade-off is that the interest rate is lower than a standard CD. These are worth considering if you think you might need the money but want a rate better than a savings account.

Before you open a CD, read the disclosure document the bank provides. It will tell you the exact penalty amount and when it applies. Some banks charge no penalty if you withdraw after a certain number of days have passed, even if the full term has not ended.

How CDs compare to savings accounts and money market accounts

A regular savings account has no term — you can withdraw money whenever you want. The trade-off is that the interest rate is much lower, often less than 1 percent. A CD locks you in but pays significantly more, sometimes two to three times as much.

A money market account sits between the two. It usually pays more than a savings account but less than a CD, and you can write checks or make withdrawals, though there are limits on how many per month. If you think you might need some of your money but want a better rate than savings, a money market account might work better than a CD.

The right choice depends on your situation. If you have money you will not need for a year or more, a CD locks in a good rate. If you might need the money sooner, a savings account or money market account gives you flexibility, even if the rate is lower.

Laddering CDs to balance rate and access

Some people use a strategy called CD laddering to get higher rates while still having access to some of their money regularly. 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 roll it into a new five-year CD.

This approach gives you regular access to portions of your money without paying early withdrawal penalties. It also lets you take advantage of rising interest rates — when a one-year CD matures and rates have gone up, you can lock in the new higher rate for the next five years.

Laddering works best when you have a larger amount to invest and you are comfortable managing multiple CDs. If you only have a small amount, the extra complexity may not be worth it.

Tax treatment of CD interest

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, and you will report that on your tax return. You owe federal income tax on the interest, and possibly state income tax depending on where you live.

This matters when you compare CD rates to other investments. A CD paying 5 percent might net you only 3.5 percent after taxes if you are in a higher tax bracket. If you hold the CD in a tax-advantaged account like an IRA, you do not owe tax on the interest until you withdraw from the account.

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 typically three to six months of interest, though it varies by bank and CD term. Some banks offer no-penalty CDs that let you withdraw without a fee, but the interest rate is lower than a standard CD.

What is the FDIC insurance limit on CDs?

The FDIC insures up to $250,000 per depositor, per bank. If you have multiple CDs at the same bank, the total coverage across all of them is $250,000. If you want to insure more than $250,000, you can open CDs at different banks.

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

Most banks automatically roll your CD into a new one at the current interest rate. You usually have a grace period of a few days to withdraw or change your mind. Check your CD agreement to see the exact timeline and the new rate you will receive.

Are CDs a good investment right now?

That depends on current interest rates and your financial goals. CDs offer a may provide return with no risk to your principal, but the rate may be lower than other investments like stocks. If you want safety and predictability over growth, a CD is worth considering.

Can I open a CD with a credit union instead of a bank?

Yes. Credit unions offer CDs with rates and terms similar to banks. Your money is insured by the NCUA instead of the FDIC, but the coverage limit is the same — $250,000 per depositor. Credit union rates are sometimes competitive with or better than bank rates.
