What a Certificate of Deposit Is

A Certificate of Deposit (CD) is a savings product where you give a bank or credit union a lump sum of money for a fixed period — typically three months to five years — in exchange for a may provide interest rate. The bank holds your money and pays you interest. When the term ends, you get back your original deposit plus the interest earned.

The tradeoff is straightforward: you agree not to touch the money until the maturity date. If you withdraw before that date, the bank charges an early withdrawal penalty, which is a fee that reduces how much you get back. The penalty amount varies by institution and by how long the CD term is.

CDs are different from regular savings accounts because the interest rate is locked in from the start and is almost always higher than what a savings account pays. You know exactly how much you will have at the end of the term, assuming you do not withdraw early.

Key Takeaways

  • A CD pays a fixed interest rate for a set period, and you cannot withdraw the money without paying a penalty until the maturity date arrives.
  • Early withdrawal penalties vary by bank and CD term length, but they typically range from one month to one year of interest, depending on what the bank's terms state.
  • When a CD matures, you can withdraw the money penalty-free, let it roll over into a new CD at the current rate, or move it elsewhere.
  • CDs are insured by the FDIC (at banks) or NCUA (at credit unions) up to $250,000 per depositor, per institution, so your principal is protected even if the institution fails.
  • Longer CD terms usually pay higher interest rates than shorter ones, but you lock up your money for a longer time.

How Interest Rates and Terms Work Together

Banks set CD interest rates based on what the Federal Reserve does with short-term interest rates and what other banks are offering. A three-month CD will almost always pay less interest than a five-year CD from the same bank, because you are locking your money away for longer and the bank can use it for longer.

The interest rate you receive is fixed for the entire term. If you open a two-year CD at 4.5 percent, you will earn 4.5 percent for the full two years, even if rates drop to 2 percent next month or rise to 6 percent next year. This certainty is one reason people use CDs — you know the exact outcome before you deposit the money.

Interest compounds on a schedule the bank sets: daily, monthly, or quarterly are common. More frequent compounding means you earn slightly more, because interest gets added to your balance and then earns interest itself. The difference is usually small for shorter terms but adds up over five years or longer.

Early Withdrawal Penalties and When They explore

If you need your money before the maturity date, the bank will let you withdraw it, but you will pay a penalty. The penalty is subtracted from your balance, so you might get back less than you originally deposited if the penalty is large enough and you have not earned much interest yet.

Penalties are stated in the CD's terms and conditions, which you receive when you open the account. Common penalty structures are "three months of interest" or "six months of interest" or a flat dollar amount. A few banks offer "no-penalty CDs" that let you withdraw without a fee, but these pay lower interest rates to offset that flexibility.

The penalty applies only if you withdraw before the maturity date. Once the maturity date arrives, you can withdraw all your money with no penalty. Some banks automatically renew CDs into a new term at the current rate if you do not tell them what to do by the maturity date, so check your bank's renewal policy.

What Happens When Your CD Matures

On the maturity date, your CD term ends and you have options. You can withdraw the full amount (principal plus interest) and move it to a savings account, another CD, or somewhere else entirely. You can also let the bank roll it over into a new CD at whatever rate the bank is currently offering.

Banks typically give you a grace period — often seven to ten days — after the maturity date to decide what to do. If you do nothing during that window, the bank will renew the CD automatically. Read your account documents to find out your bank's grace period and renewal policy, because rates may have changed and you might not want the new rate.

If rates have risen since you opened your CD, a new CD at maturity will pay more. If rates have fallen, it will pay less. This is why some people use a CD ladder — opening multiple CDs with different maturity dates so that money comes due at regular intervals and you can reinvest at whatever the current rate is.

FDIC and NCUA Insurance Protection

Money in a CD at a bank is insured by the Federal Deposit Insurance Corporation (FDIC) up to $250,000 per depositor, per institution. Money in a CD at a credit union is insured by the National Credit Union Administration (NCUA) up to the same amount. This means if the bank or credit union fails, you get your money back, up to the limit.

The $250,000 limit applies to the total of all your deposits at that one institution — checking, savings, CDs, and money market accounts all count toward it. If you have $200,000 in a CD and $100,000 in a savings account at the same bank, only $250,000 is insured. The extra $50,000 is not protected.

If you want to insure more than $250,000, you can open accounts at different banks or credit unions. Each institution's $250,000 limit is separate. You can also open a CD in your name alone and another in joint names with a spouse at the same bank, and both are insured separately.

How CDs Compare to Other Savings Products

A savings account lets you withdraw money anytime without penalty, but it pays much lower interest — often less than 0.5 percent. A money market account is similar to a savings account but may pay slightly more interest and might require a higher minimum balance. Both give you flexibility that a CD does not.

A high-yield savings account at an online bank can pay nearly as much as a CD while still letting you withdraw whenever you want. The tradeoff is that the rate can change at any time, whereas a CD rate is locked in. If you think rates might fall, a CD locks in the current rate. If you think rates might rise, a savings account lets you benefit from the increase.

Treasury bills and bonds are issued by the U.S. government and are backed by the full faith and credit of the government, so they carry no bank failure risk. But they require larger minimum investments and are harder to cash in early. CDs are simpler for most people and offer FDIC insurance instead of government backing.

Tax Treatment of CD Interest

Interest earned on a CD is taxable income in the year you earn it, even if you do not withdraw the money. If you earn $500 in interest during the year, you owe income tax on that $500 in that tax year. The bank will send you a Form 1099-INT showing how much interest you earned, and you report it on your tax return.

If you withdraw early and pay a penalty, you can deduct the penalty from your taxable interest income. So if you earned $500 in interest but paid a $200 penalty, you report $300 as taxable interest. Keep records of the penalty so you can document it on your return.

CDs held in a traditional IRA or Roth IRA have different tax rules. Interest in a traditional IRA is not taxed until you withdraw from the IRA. Interest in a Roth IRA is not taxed at all if you follow the withdrawal rules. Talk to a tax professional if you are using a CD inside a retirement account.

Frequently Asked Questions

Can I withdraw from a CD before it matures?

Yes, but you will pay an early withdrawal penalty set by your bank. The penalty is subtracted from your balance, so you might get back less than you put in. The penalty amount is in your CD's terms and conditions, which you should read before opening the account.

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

A CD locks your money for a set term and pays a higher, fixed interest rate. A savings account lets you withdraw anytime but pays much lower interest that can change. Choose a CD if you do not need the money for several months or years. Choose a savings account if you want to keep money accessible.

What happens if the bank fails while I have a CD?

The FDIC insures your CD up to $250,000 if the bank is FDIC-insured, or the NCUA insures it up to $250,000 if it is a credit union. You will get your principal and accrued interest back, even if the institution closes. Check your bank's or credit union's insurance status on the FDIC or NCUA website.

Do I have to renew my CD when it matures?

No. When your CD matures, you can withdraw the money, move it to another account, or open a different CD. If you do nothing, most banks will automatically renew it into a new CD at the current rate. Check your account documents for your bank's renewal policy so you know what will happen.

Is CD interest taxed?

Yes. Interest earned on a CD is taxable income in the year you earn it. Your bank sends you a Form 1099-INT showing the interest, and you report it on your tax return. If you pay an early withdrawal penalty, you can deduct it from the taxable interest amount.
