A certificate of deposit (CD) is one of the safest ways to earn interest on your savings. Here is everything you need to know about how CDs work, what rates look like in 2026, and when they make sense for you.
What Is a CD?
A certificate of deposit is a savings account with a fixed interest rate and a fixed term. You deposit a lump sum, agree not to withdraw it for a set period (the term), and earn a guaranteed return. When the term ends, you get your original deposit plus the interest earned.
Banks and credit unions offer CDs. They are insured by the FDIC (banks) or NCUA (credit unions) up to $250,000 per depositor, making them one of the lowest-risk savings vehicles available.
How CDs Work
- You deposit money into a CD — typically a minimum of $500 to $1,000, though some banks have no minimum.
- You choose a term: anywhere from 3 months to 5 years.
- The bank pays a fixed annual percentage yield (APY) for the full term.
- At maturity (when the term ends), you receive your deposit plus interest.
- You can reinvest in a new CD or move the money elsewhere.
CD Rates in 2026
CD rates vary by bank, term length, and the broader interest rate environment. In 2026, high-yield CDs at online banks are offering competitive rates compared to traditional savings accounts at big banks.
Online banks and credit unions typically offer the highest CD rates. Checking comparison sites like Bankrate or NerdWallet helps you find the best current rate for your preferred term.
As a general rule, longer terms offer higher rates — but not always. Sometimes short-term CDs (3–6 months) offer better rates when banks are expecting rate cuts.
What Happens If You Withdraw Early?
Most CDs charge an early withdrawal penalty if you take money out before the term ends. Typical penalties range from 60 to 180 days of interest, depending on the bank and term length.
For example, if a 1-year CD has a 90-day interest penalty and you withdraw at 6 months, you lose 90 days of interest from your total return.
No-penalty CDs allow early withdrawals without a fee, but they typically offer slightly lower rates. They are a good option if you might need access to the funds.
Types of CDs
Traditional CD — fixed rate, fixed term, early withdrawal penalty. The most common type.
No-penalty CD — lets you withdraw without a fee, usually after an initial lockup period of 6–7 days.
Bump-up CD — allows you to request a rate increase once during the term if rates rise. Usually offered with lower starting rates.
Step-up CD — the rate automatically increases at preset intervals during the term.
Jumbo CD — requires a large minimum deposit (typically $100,000+) and may offer slightly higher rates.
Brokered CD — purchased through a brokerage account. Can be sold on the secondary market before maturity, avoiding the early withdrawal penalty.
CD Laddering Strategy
A CD ladder splits your savings across multiple CDs with different maturity dates. For example, instead of putting $10,000 in a single 5-year CD, you put $2,000 each in 1-year, 2-year, 3-year, 4-year, and 5-year CDs.
As each CD matures, you either use the funds or roll them into a new 5-year CD. This gives you:
- Regular access to a portion of your money
- Exposure to higher long-term rates
- Protection against locking all your money in if rates rise
When a CD Makes Sense
CDs are a good fit when:
- You have a specific savings goal with a known timeline (a vacation in 18 months, a down payment in 3 years)
- You want a guaranteed return with zero risk
- You have more savings than your emergency fund needs
- You are nearing retirement and want to protect principal
When a CD May Not Be the Right Move
- You might need the money before the term ends
- You want to keep money accessible for opportunities
- High-yield savings accounts are offering comparable rates without locking up funds
- You have high-interest debt — paying that down beats CD returns
CD vs. High-Yield Savings Account
The main difference: a HYSA lets you access your money anytime, while a CD locks it up for the term. In exchange for the lockup, CDs typically offer slightly higher rates — though in some rate environments the gap is small.
For an emergency fund, a HYSA wins because you need access. For money you will not touch for a year or more, a CD may offer a better guaranteed return.
Bottom Line
A CD is a simple, low-risk way to earn more interest than a standard savings account on money you will not need for a defined period. Compare rates at online banks, consider a CD ladder if you have a larger amount to save, and make sure you understand the early withdrawal penalty before you commit.
