A Certificate of Deposit Is a Savings Account With a Fixed Term and a Set Interest Rate

A certificate of deposit, or CD, is a savings product where you give a bank or credit union a lump sum of money for a fixed period of time — typically anywhere from three months to five years. In exchange, the bank pays you a specific interest rate that does not change. When the term ends, you get your original money back plus the interest you earned.

The main trade-off is that you agree not to touch the money until the term is over. If you withdraw before the maturity date, you pay a penalty — usually a certain number of months' worth of interest. Because you are committing your money for a set time, banks offer higher interest rates on CDs than they do on regular savings accounts.

CDs are insured by the FDIC (Federal Deposit Insurance Corporation) if you open one at a bank, or by the NCUA (National Credit Union Administration) if you open one at a credit union. This means your money is protected up to $250,000 per account, per institution.

Key Takeaways

  • You deposit a fixed amount of money for a set term, and the bank pays you a may provide interest rate that stays the same for the entire period.
  • CDs typically pay higher interest rates than regular savings accounts because you agree not to withdraw the money early.
  • If you withdraw before the maturity date, you pay an early withdrawal penalty, which is usually several months of interest.
  • Your CD is insured up to $250,000 by the FDIC or NCUA, depending on whether you use a bank or credit union.
  • CDs come in different term lengths, from three months to five years or longer, and you can choose the one that fits your timeline.

How Interest Rates and Terms Work on CDs

When you open a CD, the bank tells you the annual percentage yield, or APY. This is the interest rate you will earn, expressed as a yearly percentage. The rate is locked in for the entire term — it will not go up or down, even if the bank's rates change.

CD terms vary widely. A three-month CD is short and lets you access your money quickly, but it usually pays a lower rate. A five-year CD locks your money away longer, but typically pays more. Some banks offer terms of six months, one year, two years, three years, and so on. The longer the term, the higher the rate tends to be — though this is not always true, and rates change based on what the Federal Reserve does.

Interest on a CD is usually compounded daily or monthly, meaning the bank calculates interest on your original deposit plus any interest you have already earned. When your CD matures, the bank adds all the interest to your account. You can then withdraw the full amount or roll it into a new CD.

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 amount varies by bank and by CD term. A common penalty is three to six months of interest, though some banks charge more or less.

For example, if you have a $10,000 CD earning 4% APY and you withdraw after six months instead of waiting a full year, the bank might deduct six months of interest (roughly $200) from what you receive. You would get your $10,000 back, but the penalty would reduce your earnings.

Before you open a CD, ask the bank what the early withdrawal penalty is. It is usually stated in the CD agreement or on the product page. Some banks offer no-penalty CDs, which let you withdraw without a penalty, though these typically pay lower interest rates than standard CDs.

When Your CD Matures and What Happens Next

When your CD term ends, the bank sends you a notice — usually 10 to 14 days before the maturity date — telling you what will happen to your money. You have a few options: withdraw the full amount, open a new CD with the same bank, or move the money elsewhere.

If you do nothing, many banks automatically renew your CD into a new one with the same term at the current interest rate. This can be convenient, but the new rate may be lower than what you earned before. Read the renewal notice carefully so you know what rate you are getting.

Some people use CDs as a savings ladder: they open multiple CDs with different maturity dates so that money becomes available at different times. For example, you might open a one-year CD, a two-year CD, and a three-year CD all at once. As each one matures, you can decide whether to renew it or use the money.

CDs Versus Regular Savings Accounts and Money Market Accounts

The main difference between a CD and a regular savings account is flexibility and interest rate. A savings account lets you deposit and withdraw money whenever you want, but it pays a much lower interest rate — often less than 0.5% APY. A CD pays significantly more, but you cannot touch the money without a penalty.

A money market account sits in the middle. It typically pays more than a savings account but less than a CD, and it gives you limited check-writing or withdrawal privileges — usually three to six withdrawals per month. If you need some access to your money but want better returns than a savings account, a money market account might work. If you know you will not need the money for a set period, a CD usually pays the most.

The choice depends on your situation. If you have an emergency fund, keep it in a savings account where you can reach it quickly. If you have money you will not need for six months or longer, a CD can earn you more interest with no risk.

Who Should Consider Opening a CD

CDs work best for people who have money they know they will not need for a specific amount of time. If you are saving for a down payment on a house in two years, or you have a bonus you want to set aside, a CD lets you earn a may provide return without worrying about market risk.

CDs are also useful if you want predictability. Unlike stocks or bonds, the interest rate on a CD does not change. You know exactly how much money you will have when the term ends. This makes CDs popular with people who are close to retirement or who straightforward prefer not to take investment risk.

CDs are less useful if you might need the money before the term ends, or if you want the flexibility to access your savings. The early withdrawal penalty can eat into your earnings, so a CD only makes sense if you are confident you can leave the money alone.

How to Open a CD

Opening a CD is straightforward. You can open one at any bank or credit union that offers them. Many banks let you open a CD online in a few minutes. You will need to choose the term length, decide how much to deposit, and provide your personal information and funding source.

When you open a CD online, the bank transfers money from your checking or savings account to fund the CD. Some banks also let you open a CD in person at a branch. The process is the same: you choose your term, make your deposit, and the bank issues you a CD agreement that shows the rate, term, and maturity date.

Before you open a CD, compare rates at different banks. CD rates vary, and a higher rate can make a real difference over time. Some online banks pay significantly more than brick-and-mortar banks. You can also check whether the bank or credit union is FDIC or NCUA insured, so you know your money is protected.

Frequently Asked Questions

Can I withdraw money from a CD before it matures?

Yes, but you will pay an early withdrawal penalty. The penalty is usually three to six months of interest, though it varies by bank and CD term. Some banks offer no-penalty CDs that let you withdraw without a fee, though these pay lower rates. Check your CD agreement to see what the penalty is before you open the account.

What happens if I do not withdraw my money when the CD matures?

Most banks automatically renew your CD into a new one with the same term at the current interest rate. This happens during a grace period, usually 10 to 14 days after maturity. If you do not want to renew, you can withdraw the money or move it to a different product during this window. Read the renewal notice the bank sends you so you know what rate you are getting.

Is my money safe in a CD?

Yes, your CD is insured up to $250,000 by the FDIC if you open it at a bank, or by the NCUA if you open it at a credit union. This means if the bank fails, your money is protected. Make sure the institution you choose is FDIC or NCUA insured before you open an account.

Do I pay taxes on CD interest?

Yes. The interest you earn on a CD is taxable income. The bank will send you a 1099-INT form at the end of the year showing how much interest you earned, and you report that on your tax return. Some people open CDs in retirement accounts like IRAs to defer taxes on the interest.

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

A savings account lets you deposit and withdraw money anytime and pays a low interest rate, usually under 0.5% APY. A CD locks your money for a set term and pays a much higher rate, but you cannot withdraw without a penalty. Choose a savings account if you need access to your money, and a CD if you have money you will not need for several months or longer.
