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

A certificate of deposit (CD) is a savings account where you agree to leave money untouched for a specific period—usually three months to five years—and the bank pays you a fixed interest rate in return. You deposit a lump sum upfront, the bank holds it, and at the end of the term you get your original money back plus the interest earned. The longer you lock the money away, the higher the interest rate typically is.

The tradeoff is straightforward: you give up access to your cash for a defined period. If you withdraw before the term ends, you pay an early withdrawal penalty—usually a few months' worth of interest, though the exact amount varies by bank and CD length. This penalty structure is what makes CDs different from regular savings accounts, where you can pull money out anytime without cost.

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

Key Takeaways

  • You deposit a fixed amount, agree not to touch it for a set term (three months to five years), and receive a may provide interest rate that does not change.
  • Early withdrawal before the term ends triggers a penalty, usually several months of interest, so only deposit money you can afford to leave alone.
  • Interest rates on CDs are higher than regular savings accounts because you are giving up access to your money for a defined period.
  • FDIC insurance protects your deposit up to $250,000 per bank, so your principal is safe regardless of what happens to the bank.
  • When your CD matures, you can withdraw the money, open a new CD, or let it roll into a new term at the bank's current rate.

How interest rates and terms work together

CD interest rates are fixed when you open the account and do not change for the entire term, even if the bank raises or lowers rates later. This means if you lock in a 4.5% rate on a one-year CD, you earn 4.5% for the full year regardless of market conditions. That predictability is valuable when rates are falling, but it also means you miss out if rates rise.

Longer terms almost always pay higher rates than shorter ones. A three-month CD might pay 4%, a one-year CD might pay 4.5%, and a five-year CD might pay 5%. The bank is compensating you for tying up your money for longer. However, rates vary widely between banks—online banks often pay more than brick-and-mortar branches—so shopping around matters.

Interest is usually compounded daily or monthly and added to your account at maturity. Some CDs allow you to withdraw interest before the term ends without penalty, but the principal stays locked. Check your CD's terms to know whether interest compounds and when it is paid out.

Early withdrawal penalties and what they cost

If you need your money before the CD matures, you can withdraw it, but you will pay a penalty. The penalty is typically expressed as a number of months of interest—for example, "three months of interest" or "180 days of interest." On a $10,000 CD earning 4.5% annually, three months of interest is about $112.50, so that is what you would lose.

Some banks charge a flat dollar amount instead, and a few charge a percentage of the principal. The penalty is deducted from your account when you withdraw, so you receive less than you deposited plus earned interest. Always read the CD's terms before opening it so you know the exact penalty structure.

A few banks offer no-penalty CDs that let you withdraw your money early without losing interest, though the interest rate is usually lower than a standard CD. These are worth considering if you are not certain you can leave the money untouched for the full term.

What happens when your CD reaches maturity

When your CD term ends, the bank sends you a notice (usually 10 to 30 days before maturity) telling you what happens next. You have three main options: withdraw the money, open a new CD, or let it roll over automatically into a new CD at the bank's current rate.

If you do nothing, most banks automatically renew your CD into a new term at the same length—a one-year CD rolls into another one-year CD—but at whatever interest rate the bank is currently offering. This can work in your favor if rates have risen, but it locks you in again if rates have fallen. Read the maturity notice carefully and act before the deadline if you want to move your money elsewhere.

Some banks offer a grace period—usually 7 to 10 days after maturity—during which you can withdraw your money without penalty. After that window closes, if you have not acted, the CD automatically renews and you are locked in again. Mark your calendar when your CD matures so you do not miss this window.

CD ladders and how to use them

A CD ladder is a strategy where you open multiple CDs with different maturity dates so that money becomes available at regular intervals. For example, you might open five $2,000 CDs with terms of one, two, three, four, and five years. Each year, one CD matures and you can withdraw the money, reinvest it, or use it for expenses.

Laddering solves two problems at once: you capture higher rates from longer-term CDs while still having regular access to portions of your money. When a CD matures, you can reinvest that amount into a new five-year CD, keeping the ladder going. This approach works best when you have a lump sum to invest and want to balance safety with some liquidity.

Laddering requires more attention than a single CD—you have to track multiple maturity dates and decide what to do with each one when it matures. But for people who want to earn CD rates without locking all their money away for years, it is a practical middle ground.

CDs versus savings accounts and money market accounts

The main difference between a CD and a regular savings account is access and rate. A savings account lets you deposit and withdraw money anytime without penalty, but the interest rate is usually much lower—often under 0.5% at traditional banks. A CD pays significantly more—currently 4% to 5% at many online banks—but you cannot touch the money without paying a penalty.

A money market account sits between the two. It typically pays more interest than a savings account but less than a CD, and it gives you limited withdrawal rights—usually three to six withdrawals per month without penalty. Money market accounts are useful if you need some access to your money but want better rates than savings, though they are less predictable than CDs.

Choose a CD if you have money you will not need for several months or longer and want the highest may provide rate. Choose a savings account if you need frequent access. Choose a money market account if you want a middle ground—better rates than savings but more flexibility than a CD.

How to open a CD and what to watch for

Opening a CD is straightforward: you choose a bank, select a term and deposit amount, and transfer money to fund it. Most banks let you open CDs online in minutes. You will need to provide your Social Security number, address, and banking information. The money is typically transferred from your linked bank account within one to three business days.

Before opening, compare rates across multiple banks—online banks almost always pay more than branches. Check the early withdrawal penalty, the compounding frequency, and whether interest is paid at maturity or monthly. Confirm the FDIC insurance limit: if you are depositing more than $250,000, spread it across multiple banks to stay within the insurance cap.

Read the maturity notice when it arrives and set a reminder on your calendar. Do not assume the bank will contact you again or that you will remember the date. Many people miss the grace period and get locked into a new CD at a lower rate simply because they forgot to act.

Frequently Asked Questions

Can I withdraw money from a CD before it matures?

Yes, but you will pay an early withdrawal penalty, usually several months of interest. The exact penalty depends on the bank and the CD term. Some banks offer no-penalty CDs that let you withdraw without losing interest, though the rate is typically lower.

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

A savings account lets you withdraw money anytime without penalty but pays very low interest, usually under 0.5%. A CD locks your money for a set term and pays much higher interest—currently 4% to 5% at many banks—but charges a penalty if you withdraw early.

Are CDs safe if the bank fails?

Yes. The FDIC insures CDs up to $250,000 per depositor per bank, so your money is protected even if the bank goes under. If you have more than $250,000, open CDs at different banks to stay within the insurance limit.

What happens if I do nothing when my CD matures?

Most banks automatically renew your CD into a new term at the same length but at the bank's current interest rate. You usually have a grace period of 7 to 10 days after maturity to withdraw the money without penalty. After that, you are locked in again.

Do I have to pay taxes on CD interest?

Yes. CD interest is taxable income and must be reported on your tax return. The bank will send you a 1099-INT form at the end of the year showing how much interest you earned. Interest is taxed at your ordinary income tax rate, not as capital gains.
