A CD locks your money for a set time in exchange for a higher interest rate

A certificate of deposit (CD) is a savings product where you give a bank or credit union a lump sum of money and agree not to touch it for a fixed period — typically three months to five years. In return, the institution pays you a fixed interest rate, which is almost always higher than what you'd earn in a regular savings account. When the CD reaches its maturity date, you get back your original deposit plus all the interest earned.

The trade-off is straightforward: you lose access to your money during the CD term. If you withdraw before the maturity date, you pay an early withdrawal penalty, which is a fee that reduces how much you get back. The penalty amount varies by bank and by CD term length — a three-month CD might charge one month of interest, while a five-year CD might charge six months of interest or more.

CDs 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. This means if the institution fails, you're protected up to $250,000 per account owner, per institution. That protection covers both your deposit and the interest you've earned.

Key Takeaways

  • You deposit a fixed amount of money and agree not to withdraw it for a set period, usually between three months and five years.
  • The interest rate on a CD is locked in when you open it and does not change, even if market rates rise or fall during your CD term.
  • Withdrawing money before the maturity date triggers an early withdrawal penalty that reduces your total return.
  • Your CD is insured up to $250,000 by the FDIC or NCUA, protecting both your deposit and earned interest if the institution fails.
  • When your CD matures, you receive your original deposit plus all accrued interest, and you can then decide whether to open a new CD or move the money elsewhere.

How interest rates and terms work together

The interest rate you receive depends on two things: what the bank is currently offering, and how long you commit your money. Longer terms almost always come with higher rates. A one-year CD might pay 4.5 percent, while a five-year CD from the same bank might pay 5.2 percent. This is because the bank wants to keep your money longer and is willing to pay more for that certainty.

Your rate is fixed, meaning it does not change for the entire CD term. If you open a two-year CD at 4.8 percent and interest rates drop to 3 percent the next month, you still earn 4.8 percent. Conversely, if rates climb to 6 percent, you're locked into 4.8 percent. This is why timing matters — if you believe rates are about to fall, locking in a current rate protects you. If you think rates will rise, a shorter CD term lets you reinvest at a higher rate sooner.

Interest on a CD is usually compounded daily or monthly, meaning you earn interest on your interest. The more frequently it compounds, the slightly more you earn. Most banks show you the annual percentage yield (APY), which accounts for compounding and tells you the true annual return.

What happens when your CD reaches maturity

On the maturity date, your CD term ends and the bank stops earning interest. At that point, you have a window — usually 7 to 10 days, though it varies by bank — to decide what to do with the money. You can withdraw it in full, move it to another account, or open a new CD.

If you do nothing during that window, many banks automatically renew your CD into a new term at the current interest rate. This is convenient if you want to keep your money locked up, but it means you might miss a chance to shop around for a better rate elsewhere. Read your CD agreement to see what your bank's renewal policy is, and set a calendar reminder for a few weeks before maturity so you can decide in advance.

When the CD matures, the bank sends you a statement showing your original deposit, the total interest earned, and the full amount available to you. You can withdraw this as cash, transfer it to a checking or savings account, or use it to open a new CD at the same bank or elsewhere.

Early withdrawal penalties and how they work

If you need your money before the maturity date, you can withdraw it, but the bank will charge a penalty. The penalty is subtracted from your balance, so you might get back less than you deposited if the penalty is large enough and you haven't earned much interest yet.

Penalty amounts are set by the bank and disclosed in your CD agreement. Common structures include a flat fee (for example, $25), a percentage of the deposit (for example, 1 percent), or a number of months of interest (for example, three months of interest). A $10,000 CD earning 5 percent annually might have a penalty of three months of interest, which would be about $125. If you withdrew after six months, you'd get back $10,000 plus $250 in interest, minus the $125 penalty, for a total of $10,125.

Some banks offer no-penalty CDs, which let you withdraw without a penalty, though the interest rate is usually lower than a standard CD. These are worth considering if you're uncertain whether you'll need the money.

CD laddering and other strategies

One way to balance the security of a CD with access to your money is CD laddering. You open multiple CDs with different maturity dates — for example, one that matures in one year, one in two years, and one in three years. As each CD matures, you can withdraw that portion or reinvest it. This gives you regular access to chunks of your money while keeping the rest earning a higher rate.

Another approach is opening a CD ladder with equal amounts. If you have $10,000, you might open five $2,000 CDs maturing at different times. Every year, one CD matures and you can use that money or reinvest it. This spreads your risk and gives you flexibility without sacrificing much interest.

Some people use CDs as part of a broader savings strategy: keeping an emergency fund in a regular savings account for quick access, putting money they won't need for a few years in a CD for a higher rate, and investing longer-term money in other vehicles. CDs work best for money you're confident you won't need during the term.

Where to find and compare CD rates

CD rates vary significantly between banks and credit unions. Your local bank might offer 3.5 percent on a one-year CD, while an online bank might offer 5.0 percent for the same term. Shopping around can mean hundreds of dollars in additional interest over the CD's life.

You can compare rates on financial websites that aggregate CD offerings, or by visiting banks' websites directly. Look at the APY, the term length, the minimum deposit required, and the early withdrawal penalty. Some banks require a minimum deposit of $500, while others require $25,000 or more. Online banks typically offer higher rates than brick-and-mortar banks because they have lower overhead costs.

Credit unions sometimes offer competitive rates and may have lower minimum deposits than banks. If you're a member of a credit union, check what they offer before assuming a bank has the best rate. Remember that the FDIC and NCUA insurance limits are per institution, so if you're opening multiple CDs, spreading them across different banks or credit unions protects more of your money.

Taxes on CD interest

The interest you earn on a CD is taxable income in the year you earn it, even if you don't withdraw the money. The bank will send you a Form 1099-INT at the end of the tax year showing how much interest you earned. You report this on your tax return.

If you earn more than $10 in interest from a single bank, the bank is required to send you a 1099-INT. If you have CDs at multiple institutions, you'll receive a separate form from each one. Keep these forms with your tax records.

The tax rate on CD interest depends on your overall income and tax bracket. If you're in a higher bracket, the after-tax return on your CD is lower than the stated APY. Some people use CDs in tax-advantaged accounts like IRAs to defer or reduce taxes on the interest, though there are contribution limits and rules around those accounts.

Frequently Asked Questions

Can I withdraw money from a CD before it matures?

Yes, you can withdraw anytime, but you'll pay an early withdrawal penalty set by your bank. The penalty is deducted from your balance, so you might receive less than your original deposit if the penalty is large. Some banks offer no-penalty CDs that let you withdraw without a fee, though they pay lower interest rates.

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

A savings account lets you deposit and withdraw money anytime without penalty, but pays a lower interest rate. A CD locks your money for a set term and pays higher interest, but charges a penalty if you withdraw early. Choose a savings account for money you might need soon, and a CD for money you won't touch for months or years.

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 new CD. If you don't take action during the renewal window (usually 7 to 10 days), many banks automatically renew into a new CD at the current rate. Check your bank's policy and set a reminder before maturity so you can decide in advance.

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

Your CD is insured up to $250,000 by the FDIC (if at a bank) or NCUA (if at a credit union). If the institution fails, the insurance agency pays you your full deposit plus all earned interest, up to the limit. This protection applies even if you can't access your money during the CD term.

Is a CD a good place to put money I might need in an emergency?

CDs are not ideal for emergency funds because withdrawing early costs you a penalty. Keep three to six months of expenses in a regular savings account for emergencies, and use CDs only for money you're confident you won't need during the CD term. No-penalty CDs are a middle ground if you want slightly higher interest with more flexibility.
