How to buy a CD and what to expect
Buying a CD is simpler than buying stocks or bonds. You pick a bank or credit union, choose how long to lock your money away (the term), and deposit a lump sum. The bank pays you a fixed interest rate for that entire period. When the term ends, you get your principal back plus the interest you earned. You can then withdraw the money, renew the CD at the same bank, or move it elsewhere.
The main trade-off is time for rate. A 12-month CD pays less than a 5-year CD because you are giving the bank access to your money for longer. You also cannot touch the money without penalty until the term ends — that is the cost of locking in a may provide rate. Most banks charge a penalty equal to a few months of interest if you withdraw early.
You do not need to pick a specific stock or bond. You do not need to monitor daily prices. You just need to decide how much to deposit, how long you can leave it alone, and which bank offers the best rate for that term.
Key Takeaways
- You deposit a fixed amount at a bank or credit union, choose a term (3 months to 5 years is common), and receive a may provide interest rate for that entire period.
- The longer the term, the higher the rate — a 5-year CD pays more than a 1-year CD, but your money is locked away longer.
- Withdrawing before the term ends triggers an early withdrawal penalty, usually equal to a few months of interest, so only deposit money you will not need.
- You can compare CD rates across banks using rate-tracking websites, and online banks typically offer higher rates than brick-and-mortar branches.
- Your deposit is insured up to $250,000 per bank by the FDIC (or NCUA if you use a credit union), so your principal is protected even if the bank fails.
Where to open a CD and how rates differ
You can open a CD at any bank, credit union, or brokerage firm. Online banks (such as Marcus, Ally, or Discover) almost always offer higher rates than traditional banks with physical branches, because they have lower overhead costs. If you already have a checking account at a brick-and-mortar bank, that bank will offer you a CD, but the rate will usually be lower than what you can find online.
Rates vary by term and by institution. A 1-year CD at one bank might pay 4.5%, while a 1-year CD at another pays 4.8%. That 0.3% difference sounds small, but on a $10,000 deposit it means $30 more in interest over the year. On a $50,000 deposit it means $150 more. Websites like Bankrate, DepositAccounts, and CD Ladder track rates across hundreds of banks and let you filter by term and sort by rate.
Credit unions often offer competitive rates, especially if you are a member. You do not need to work for a specific employer or live in a specific area to join many credit unions — some are open to anyone in a geographic region, and others let you join if you donate to a may have access to charity. Your deposit at a credit union is insured by the NCUA up to $250,000, the same as FDIC insurance at a bank.
Choosing a term that matches your timeline
The term is how long your money stays locked in the CD. Common terms are 3 months, 6 months, 1 year, 2 years, 3 years, and 5 years. Some banks offer 7-year or 10-year CDs, and some offer terms as short as 1 month. The longer the term, the higher the rate — this is the bank's way of compensating you for giving up access to your money for longer.
Pick a term based on when you actually need the money. If you have an emergency fund that is fully stocked and you have $5,000 you will not touch for 3 years, a 3-year CD makes sense. If you might need the money in 18 months, a 1-year CD is safer — you avoid the early withdrawal penalty, and you can decide what to do with the money when it matures. If you are unsure, a shorter term is the better choice, because you can always roll the money into a new CD when it matures.
Some people use a CD ladder to balance rate and access. You buy five 1-year CDs with $2,000 each, but stagger the maturity dates so one matures every few months. This way you earn a higher rate than a savings account, but you always have some money becoming available without penalty. A CD ladder takes more work to set up and manage, but it is a common strategy for people with larger sums.
How to open a CD in practice
Once you have chosen a bank and a term, the process takes 10 to 15 minutes. You will need your Social Security number, a government-issued ID, and proof of address (a recent utility bill or bank statement works). You will also need the amount you want to deposit — the minimum is usually $500 to $2,500, though some banks have no minimum.
Most banks let you open a CD online without visiting a branch. You create an account, enter your personal information, choose the CD term and amount, and link a bank account to fund the deposit. The bank will verify your identity and may ask a few security questions. Once approved, the money moves from your linked account to the CD, usually within one business day.
If you open a CD at a bank where you already have a checking account, the process is even faster — you can often fund the CD directly from your existing account without re-entering your information. If you are opening a CD at a new bank, you will go through a full account-opening process, which is still straightforward but takes a bit longer.
What happens when your CD matures
When the term ends, your CD matures. The bank will send you a notice a few weeks before the maturity date, usually by email or mail. At that point you have a few options: withdraw the money, renew the CD at the same bank, or move the money to a CD at a different bank.
If you do nothing, most banks will automatically renew your CD at the current rate for the same term. This is convenient if rates have not changed much, but if rates have risen, you might miss out by not shopping around. If rates have fallen, auto-renewal is fine. Read the maturity notice carefully to see what the renewal rate will be, and decide whether to accept it or move your money.
If you want to withdraw the money, you can transfer it to your checking account at the same bank, or request a check. The money is yours — you have already earned all the interest, and the term is over, so there is no penalty. If you want to move the money to a CD at a different bank, you can withdraw it and deposit it at the new bank within a few days without losing any interest.
Understanding early withdrawal penalties
If you need your money before the maturity date, the bank will charge you an early withdrawal penalty. The penalty is usually expressed as a number of months of interest. A CD with a 6-month interest penalty means the bank will subtract 6 months of interest from your payout. On a $10,000 CD earning 4.5% annually, that is roughly $225 in lost interest.
The penalty varies by bank and by term. Longer-term CDs usually have larger penalties — a 5-year CD might have a 12-month penalty, while a 1-year CD might have a 3-month penalty. Some banks publish the penalty upfront; others do not. Before you open a CD, ask the bank what the early withdrawal penalty is, or look for it in the terms and conditions.
The penalty is deducted from your interest, not from your principal. You always get your original deposit back. If you withdraw early and the penalty is larger than the interest you have earned so far, you will lose some of the interest, but you will not owe the bank money. This is why it is important to only deposit money in a CD if you are confident you will not need it before the term ends.
How FDIC and NCUA insurance protects your money
When you open a CD at a bank, your deposit is insured by the FDIC (Federal Deposit Insurance Corporation) up to $250,000. When you open a CD at a credit union, your deposit is insured by the NCUA (National Credit Union Administration) up to $250,000. This means if the bank or credit union fails, the government will return your money, including any interest you have earned so far.
The insurance covers the principal plus accrued interest. If your CD matures while the bank is failing, you are covered. If your CD is still locked in, you are covered. The insurance is automatic — you do not need to register or do anything. It applies to each depositor at each institution separately, so if you have $250,000 at Bank A and $250,000 at Bank B, both are fully insured.
If you have more than $250,000 to invest in CDs, you can spread the money across multiple banks to stay within the insurance limit at each one. For example, $500,000 split between two banks means $250,000 at each, and both amounts are fully insured. This is a common strategy for people with large savings.
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 a few months of interest, and it is deducted from what you receive. You always get your principal back. Only withdraw early if you truly need the money, because the penalty can be substantial.
What is the difference between a CD and a savings account?
A savings account has no term — you can withdraw money anytime without penalty. A CD locks your money for a set period and pays a higher rate in exchange. Savings accounts are better for emergency funds; CDs are better for money you will not need for months or years.
Do I have to pay taxes on CD interest?
Yes. CD interest is taxable income. The bank will send you a 1099-INT form at tax time showing how much interest you earned. You report this on your tax return. If you earn more than $10 in interest, the bank must send you the form.
What happens if I need my money before the CD matures?
You can withdraw it, but you will lose some or all of the interest you have earned as an early withdrawal penalty. The exact amount depends on the bank and the term. Before opening a CD, confirm the penalty so you know what it will cost if an emergency happens.
Should I open a CD at my current bank or shop around?
Shop around. Online banks almost always offer higher rates than brick-and-mortar banks. Even a 0.5% difference adds up quickly on larger deposits. Use a rate-tracking website to compare terms and rates, then open the CD at whichever bank offers the best rate for your chosen term.
