A certificate of deposit (CD) is a type of savings account that holds a fixed amount of money for a set period and pays a fixed interest rate. As of August 2026, the national average annual percentage yield (APY) on a one-year CD is about 1.68%, according to the Federal Deposit Insurance Corporation (FDIC), while top online banks and credit unions offer one-year CDs with APYs up to around 4.40%.
CDs typically earn higher interest than a traditional savings account, but you'll usually pay an early withdrawal penalty if you take your money out before the CD matures. Understanding how a CD account works can help you decide whether it's the right fit for your savings goals.

Key Takeaways
A CD account locks in a fixed rate for a set term: You deposit a lump sum, earn a guaranteed APY and get your principal plus interest back at maturity.
CDs usually pay more than a regular savings account: Top one-year CDs recently ran about 4.10% to 4.40% APY, versus a national average near 1.68% to 2.03%.
Early withdrawals cost you: Pulling money before maturity typically triggers a penalty equal to three to 12 months' interest, depending on the term.
Your money is federally insured: CDs at FDIC banks and NCUA credit unions are protected up to $250,000 per depositor, per institution, per ownership category.
CDs fit goals with a deadline: They're best for planned expenses like a down payment or wedding — not an emergency fund you might need fast.
A CD ladder balances access and yield: Staggering maturity dates gives you regular access to cash while capturing longer-term rates.

A CD is a type of deposit account offered by banks and credit unions. When you open a CD, you deposit a lump sum of money and choose a term, which may range from a few months to several years. Your financial institution pays a fixed APY during that time, and your rate won't change before the CD matures.
In return for locking in that rate, you agree to leave your money in the account until the end of the term. If you keep the funds in the CD until maturity, you'll receive your original deposit plus the interest you've earned.
How Does a CD Account Work?
Opening a CD account is relatively simple. You choose a bank or credit union, make an initial deposit, and select the term that best matches your savings goal. The financial institution locks in your APY for the length of the term, allowing your money to earn interest without being affected by changing market rates.
Most banks and credit unions require a minimum deposit of $500 to $2,500 to open a CD. Some online banks let you start with no minimum, and jumbo CDs usually require $100,000 or more.
Once the CD reaches maturity, you'll generally have three options:
Withdraw your original deposit and earned interest
Roll the money into a new CD
Transfer the funds to another account
Most CDs don't allow penalty-free withdrawals before maturity, so it's important to choose a term that fits your timeline.
CD Interest Example
If you put $5,000 into a one-year CD with a 4.00% APY, you would earn about $200 in interest by the end of the term. That leaves you with $5,200 when the CD matures — as long as you leave the money alone until the end date.
Why Do People Open CD Accounts?
Many savers choose CD accounts because they offer predictable returns with very little risk. Unlike investments whose values fluctuate, a CD provides a guaranteed interest rate for the entire term.
A CD may be a good option if you want to:
Earn more interest than a traditional savings account may offer
Save for a future purchase or expense
Keep money set aside without the temptation to spend it
For example, if you want to start a vacation fund, investing in a CD can help your money grow while keeping it separate from your everyday spending.
Common CD Terms and What They Mean
Here is some of the terminology you may see when exploring CD options:
Annual percentage yield (APY): This is the total amount of interest you can earn in one year, including the effects of compounding. It's the best way to compare how much different savings accounts and CDs pay.
Fixed interest rate: An interest rate that stays the same for the entire CD term, regardless of changes in market rates.
Maturity date: The date when the CD term ends, and you can withdraw your money without paying an early withdrawal penalty.
Principal: The amount of money you originally deposited into the CD, not including any interest earned.
Interest: The money the bank pays you for keeping your deposit in the CD.
Compounding: The process of earning interest on both your original deposit and the interest you've already earned.
Grace period: A short window of time after your CD matures during which you can withdraw, renew, or transfer your money before the CD automatically renews.
CD ladder: A CD ladder is a savings strategy that spreads your money across multiple CDs with staggered maturity dates, giving you more regular access to cash while still letting you take advantage of potentially higher rates on longer-term CDs.
What Happens if You Need the Money Early?
One of the biggest tradeoffs of a CD account is limited access to your funds.
If you withdraw money before the maturity date, you'll usually pay an early withdrawal penalty. CD early withdrawal penalties are usually charged as a set number of months of interest. The exact amount depends on your CD term.
Typical early withdrawal penalties by term.
Short-term CDs (3 to 12 months): Three to six months of interest
Mid-term CDs (1 to 3 years): Six to nine months of interest
Long-term CDs (4 years or longer): Up to 12 months of interest
In some cases, withdrawing very early could even result in a reduction of your original deposit.
Because of this, CDs generally aren't the best place to keep an emergency fund or money you may need unexpectedly. Before opening an account, review the early withdrawal policy so you understand the potential costs.
CD Account vs. Savings Account
Both CD accounts and savings accounts help you grow your money, but each serves a different purpose.
Feature | CD account | Savings account |
|---|---|---|
Interest rate | Usually fixed | Usually variable |
Access to money | Limited until maturity | Available when needed |
Early withdrawal | Penalty usually applies | Typically no penalty |
Best for | Future savings goals | Emergency funds and everyday savings |
A savings account offers more flexibility because you can generally withdraw or add money whenever needed. A CD account, on the other hand, rewards you for leaving your money untouched until the end of the term.
If you're building an emergency fund, a savings account is typically the better choice. If you're saving for a planned expense with a clear deadline, a CD may help you earn more while keeping your money secure.
Are CD Accounts Safe?
CD accounts are generally considered one of the safest places to keep your money when they're opened at a Federal Deposit Insurance Corporation (FDIC)-insured bank or a National Credit Union Administration (NCUA)-insured credit union. Your deposits are protected up to applicable federal insurance limits if the financial institution fails.
The FDIC insures CDs at banks up to $250,000 per depositor, per bank, per ownership category. The NCUA covers credit union CDs up to the same $250,000 limit. That means if your bank or credit union fails, your money is protected up to that amount.
That said, a CD isn't automatically the best choice for every savings goal. While your principal is generally protected, inflation can reduce your purchasing power over time, and you'll sacrifice easy access to your money until the CD matures.
When a CD Account Makes Sense
A CD account can be a good fit when you're saving for a goal with a clear timeline and don't expect to need the money before the term ends.
You might consider opening a CD if you're saving for:
A down payment on a home
A vacation
College tuition
A wedding or other major expense
A CD may also make sense if interest rates are attractive and you want to lock in today's APY before rates decline. Because the interest rate stays fixed throughout the term, you'll know exactly what your savings can earn.
When a CD Account May Not Be the Best Choice
A CD isn't ideal for every financial situation. If there's a chance you'll need your money before the maturity date, another savings option may be a better fit.
You may want to skip a CD if you're:
Building an emergency fund
Saving money you'll need soon but don't have an exact timeline for
Planning to make regular deposits over time
Looking for long-term investment growth rather than stable returns
In these situations, a traditional or high-yield savings account (HYSA) may offer the flexibility you need without the risk of an early withdrawal penalty.

How To Choose the Right CD Account
Before opening a CD account, compare more than just the advertised interest rate.
Consider each of the following:
APY
Term length
Minimum deposit requirement
Early withdrawal penalty
Whether the bank or credit union is federally insured
Most importantly, choose a term that matches your savings goal. A slightly lower APY may be worthwhile if the maturity date better fits when you'll need the money.
Bottom Line
If you have a specific savings goal and won't need your money before the maturity date, a CD account can be a smart choice. But if flexibility is your priority, a savings account may better meet your needs. Understanding how a CD account works can help you choose the right place for your savings.
