A CD account is a savings product where you deposit money for a fixed period and receive a may provide interest rate in return

A certificate of deposit (CD) is a contract between you and a bank. You give the bank a sum of money—anywhere from $500 to $100,000 or more, depending on the bank—and agree to leave it untouched for a set time period. In exchange, the bank pays you a fixed interest rate, which is almost always higher than what you'd earn in a regular savings account. When the time period ends, you get your original deposit back plus the interest you've earned.

The key difference from a savings account is the lock-in period. With a savings account, you can withdraw money whenever you want. With a CD, you commit to leaving the money alone. If you withdraw before the maturity date—the day the CD term ends—you'll pay a penalty, usually a few months' worth of interest. That penalty is how the bank protects itself; it's counting on your money staying put so it can lend it out or invest it elsewhere.

CDs are insured by the Federal Deposit Insurance Corporation (FDIC) up to $250,000 per depositor, per bank. That means if the bank fails, your money is protected. This makes CDs one of the safest places to park cash if you know you won't need it for a while.

Key Takeaways

  • You deposit a lump sum in a CD for a fixed term—typically three months to five years—and receive a may provide interest rate that doesn't change.
  • Early withdrawal penalties usually cost you several months of interest, so CDs work best when you're certain you won't need the money until maturity.
  • CD rates are higher than savings accounts because the bank knows your money will stay invested for the full term.
  • FDIC insurance protects your deposit up to $250,000, making CDs a low-risk savings tool.
  • The interest you earn on a CD is taxable income in the year it's credited to your account.

How CD terms and interest rates work

When you open a CD, you choose the term length. Common options are 3 months, 6 months, 1 year, 2 years, 3 years, and 5 years. Some banks offer longer terms up to 10 years, and a few offer very short terms of 30 or 60 days. The longer the term, the higher the interest rate the bank will usually offer you, because the bank gets to use your money for longer.

The interest rate on a CD is fixed. It doesn't move up or down while your money is in the account. If you lock in a 2% rate on a one-year CD, you'll earn exactly 2% no matter what happens to interest rates in the broader economy. This is different from a variable-rate savings account, where the rate can change monthly.

Interest is typically credited to your account monthly, quarterly, or at maturity, depending on the bank's terms. Some banks let you choose whether to have interest paid into the CD itself (which means you earn interest on your interest) or into a linked savings account.

What happens when your CD reaches maturity

On the maturity date, your CD stops earning interest. At that point, you have a window—usually 7 to 10 days—to decide what to do with the money. You can withdraw it, move it to a different account, or roll it over into a new CD at the bank's current rates.

If you don't take action during the grace period, most banks will automatically roll your CD into a new one with the same term at whatever rate the bank is currently offering. This happens whether rates have gone up or down. If rates have dropped significantly, you may want to withdraw the money and shop around instead of accepting the automatic rollover.

Some banks notify you by mail or email before maturity; others don't. It's your responsibility to track when your CD matures so you can make an active choice rather than being locked into a new term you didn't intend.

Early withdrawal penalties and when they explore

If you need your money before the maturity date, you can withdraw it, but you'll pay a penalty. The penalty is almost always expressed as a number of months of interest. A common penalty on a one-year CD might be three months of interest; on a five-year CD, it might be six months.

Here's how it works in practice: suppose you have a $10,000 CD earning 4% annually, and the penalty is three months of interest. Three months of interest on $10,000 at 4% is $100. If you withdraw after six months, you'd get your $10,000 back, but the bank would deduct the $100 penalty. You'd walk away with $9,900, plus whatever interest you'd already earned in those six months.

Some banks offer no-penalty CDs, where you can withdraw without a penalty, though the interest rate is usually lower than a standard CD. These are worth considering if you're not completely sure you won't need the money.

CD rates vary by bank and economic conditions

CD rates are not set by the government. Each bank decides what rate to offer based on what it needs to attract deposits and what it can earn by lending that money out. This means rates vary significantly from bank to bank. A large national bank might offer 4.5% on a one-year CD while an online bank offers 5.2% for the same term.

Rates also change based on what the Federal Reserve does with its benchmark interest rate. When the Fed raises rates, banks typically raise CD rates too. When the Fed cuts rates, CD rates fall. This is why CD rates are higher right now than they were a few years ago—the Fed has kept rates elevated to combat inflation.

If you're considering a CD, it's worth checking rates at several banks, including online banks, which often offer higher rates than brick-and-mortar branches because they have lower overhead costs. The difference between a 4.5% rate and a 5.2% rate adds up quickly on larger deposits.

Who should use a CD and who shouldn't

CDs work well if you have money you won't need for a specific period—money you're saving for a down payment in two years, or funds you want to set aside for a known expense. They're also useful if you want to lock in a rate before rates fall, or if you want to spread your savings across multiple CDs with different maturity dates so money comes available at different times.

CDs don't work well if you might need the money unexpectedly, because the penalty will eat into your returns. They're also not ideal if you think interest rates are about to rise significantly, because you'll be locked into a lower rate. And if you're looking for growth beyond what interest can provide, CDs won't help—they're a savings tool, not an investment.

CDs also aren't the right choice if you're trying to minimize taxes. The interest you earn is taxable as ordinary income in the year it's credited, even if you don't withdraw it. If you're in a high tax bracket, the after-tax return on a CD might be lower than you'd expect.

How CDs compare to other savings options

A regular savings account offers flexibility—you can withdraw anytime without penalty—but the interest rate is usually much lower, often under 0.5%. A money market account sits in the middle: it offers higher rates than savings but lower than CDs, and you can usually write checks or make a limited number of withdrawals per month. A high-yield savings account at an online bank can offer rates close to CDs (sometimes 4% or higher) while keeping your money accessible.

Treasury bills and bonds are government-backed alternatives that also offer fixed rates, but they work differently—you're lending to the government rather than depositing at a bank, and you buy them through a brokerage. They're safe but less convenient for most people.

The choice depends on when you'll need the money. If it's within a year and you want the highest may provide rate, a CD makes sense. If you might need it sooner, a high-yield savings account is safer. If you're investing for longer-term growth, stocks or bonds might be more appropriate, though they carry more risk.

Frequently Asked Questions

Can I withdraw money from a CD before it matures?

Yes, but you'll pay an early withdrawal penalty, usually several months of interest. Some banks offer no-penalty CDs where you can withdraw without a fee, though the rate is typically lower. Check your CD's terms to see what the specific penalty is.

What's the difference between a CD and a savings account?

A savings account lets you withdraw anytime with no penalty but earns very low interest. A CD locks your money for a set term in exchange for a much higher rate. Choose a savings account if you need access to the money; choose a CD if you're certain you won't need it for months or years.

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

Yes. The FDIC insures CDs up to $250,000 per depositor, per bank. If the bank fails, you'll get your deposit and accrued interest back, up to that limit. This makes CDs one of the safest places to keep money.

Do I have to pay taxes on CD interest?

Yes. Interest earned on a CD is taxable as ordinary income in the year it's credited to your account, even if you don't withdraw it. Your bank will send you a 1099-INT form at tax time showing how much interest you earned.

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. This happens whether rates have risen or fallen. You should contact your bank before maturity if you want to withdraw the money or move it elsewhere instead of rolling over.
