A CD 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 a bank account that holds a fixed amount of money for a fixed period—usually anywhere from three months to five years. In exchange for leaving your money untouched until that period ends, the bank pays you a higher interest rate than you would get in a regular savings account. When the CD reaches its maturity date, you get your original money back plus the interest earned.

The trade-off is straightforward: you give up access to your cash for a defined time, and the bank rewards you with better interest. If you withdraw the money before the maturity date, you pay a penalty—usually a few months' worth of interest. This structure makes CDs useful if you have money you know you won't need for a while and want a may provide return.

Key Takeaways

  • A CD locks your money for a set term (three months to five years) and pays a fixed interest rate that is higher than a regular savings account.
  • Your money and interest are may provide—the rate does not change, and the FDIC insures deposits up to $250,000 per bank.
  • Withdrawing early triggers a penalty, usually several months of interest, so only put money in a CD if you will not need it before maturity.
  • CD rates vary by bank and term length; shopping around can mean hundreds of dollars in difference over the life of the account.

How the interest rate and term length work together

When you open a CD, you choose both the term (how long your money stays locked) and you receive a fixed interest rate for that entire period. A three-month CD might pay 4.5 percent annually, while a five-year CD at the same bank might pay 4.8 percent. Longer terms usually come with higher rates because the bank knows it will have your money for longer.

The interest compounds—meaning you earn interest on your interest—but the exact schedule depends on the bank. Some compound daily, others monthly. At maturity, the bank deposits your original deposit plus all accrued interest into your account, or you can roll it into a new CD at whatever rate the bank is offering at that time.

What happens if you need the money before maturity

Early withdrawal penalties exist specifically to discourage taking money out before the term ends. A typical penalty might be three to six months of interest, though some banks charge more and some charge less. If you withdraw from a one-year CD after six months, you might lose six months of the interest you earned, meaning you walk away with less than you would have in a regular savings account.

A few banks offer "no-penalty" CDs with slightly lower rates but no early withdrawal fee. These are worth considering if you think there is any chance you might need the money, because the penalty on a standard CD can be steep enough to wipe out your gain.

FDIC protection and what it covers

Money in a CD is insured by the Federal Deposit Insurance Corporation (FDIC) up to $250,000 per depositor, per bank. This means if the bank fails, your CD and its interest are protected up to that limit. This protection applies only to banks, not to credit unions (which are covered by the NCUA instead) or investment firms.

If you have more than $250,000 to invest, you can open CDs at multiple banks to stay within the insurance limit at each one. The FDIC counts each bank separately, so $250,000 at Bank A and $250,000 at Bank B are both fully covered.

How CD rates compare across banks and terms

CD rates change constantly and vary significantly by bank. A large national bank might offer 4.0 percent on a one-year CD, while an online bank offers 4.75 percent for the same term. Over one year on a $10,000 deposit, that difference is roughly $75. Over five years, the gap widens considerably.

Online banks and credit unions often pay higher rates than brick-and-mortar banks because they have lower overhead costs. Checking current rates across several institutions takes 15 minutes and can save you hundreds of dollars. Rate comparison websites show current offerings, though you will need to visit each bank's site to open the account.

When a CD makes sense for your money

A CD works well if you have a specific goal with a known timeline—saving for a down payment in two years, setting aside money for a car purchase in 18 months, or building an emergency fund you know you will not touch. It also makes sense if you want a may provide return and do not want to think about market risk or investment decisions.

A CD does not make sense if you might need the money sooner, if you are saving for something with an uncertain timeline, or if you believe interest rates will rise significantly in the near term (because you would be locked into a lower rate). In a rising-rate environment, a shorter-term CD lets you reinvest at higher rates when it matures.

CD laddering: spreading your money across multiple terms

One strategy to balance higher rates with access to your money is called CD laddering. Instead of putting all your money into one five-year CD, you split it across five one-year CDs. Each year, one CD matures and you can withdraw the money, reinvest it, or let it roll into a new CD at the current rate.

This approach gives you regular access points without the early withdrawal penalty, and it lets you take advantage of rate increases as they happen. If rates rise, your first CD matures in a year and you can move to a higher rate. If rates fall, you still have four CDs earning the original higher rate.

Frequently Asked Questions

Can I withdraw money from a CD before it matures?

Yes, but you will pay an early withdrawal penalty, usually three to six months of interest. Some banks charge more. A no-penalty CD avoids this but pays a slightly lower rate. Check your bank's specific terms before opening the account.

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

A savings account lets you withdraw money anytime with no penalty, but pays a much lower interest rate. A CD locks your money for a set term and pays more interest, but charges a penalty if you withdraw early. Choose based on whether you need access to the money.

Are CDs safe if the bank fails?

Yes. The FDIC insures CDs up to $250,000 per depositor per bank. If the bank fails, you get your money and interest back up to that limit. Credit union CDs are covered by the NCUA instead, with the same $250,000 limit.

Do I have to pay taxes on CD interest?

Yes. CD interest is taxable income in the year it is earned or credited to your account. The bank will send you a 1099-INT form at tax time showing how much interest you earned. This applies even if you do not withdraw the money.

What happens when my CD reaches maturity?

The bank deposits your original money plus interest into your account. You can then withdraw it, open a new CD at the current rate, or move the money elsewhere. If you do nothing, some banks automatically roll it into a new CD at the current rate—check your terms to be sure.
