A certificate of deposit locks your money away for a set time in exchange for a fixed interest rate
A certificate of deposit (CD) is an agreement between you and a bank or credit union. You give them a sum of money — anywhere from $500 to $100,000 or more, depending on the institution — and promise not to touch it for a specific period. In return, they pay you a fixed interest rate that is usually higher than what a regular savings account offers. When the time period ends, you get your original money back plus the interest earned.
The trade-off is straightforward: you lose access to your cash for months or years, and the bank gets to use that money during that time. Because the bank knows exactly how long it will hold your money, it can offer you a better rate than it would for a savings account where you can withdraw whenever you want.
CDs are issued by banks and credit unions that are insured by the Federal Deposit Insurance Corporation (FDIC) or the National Credit Union Administration (NCUA). This means your deposit is protected up to $250,000 if the institution fails — a real safety net that makes CDs one of the lowest-risk places to put money.
Key Takeaways
- You deposit a lump sum and agree not to withdraw it until the CD matures, which can range from three months to five years or longer.
- The interest rate is locked in when you open the CD and does not change, even if market rates rise or fall during your term.
- If you withdraw money before the maturity date, you pay an early withdrawal penalty that reduces your earnings or principal.
- CDs are FDIC or NCUA insured up to $250,000, making them one of the safest places to store money that you will not need soon.
- The longer the term, the higher the interest rate typically is, but you give up access to your money for that entire period.
How the interest rate and term length work together
When you open a CD, you choose both the term length and receive a fixed interest rate for that term. Common terms are three months, six months, one year, two years, three years, and five years. Some banks offer terms as short as one month or as long as ten years, but these are less common.
The interest rate you receive depends on the term you choose and the current market. Generally, longer terms pay higher rates because the bank gets to use your money for a longer period. A one-year CD might pay 4.5 percent, while a five-year CD at the same bank might pay 5.2 percent. However, this relationship is not may provide — rates depend on what the Federal Reserve is doing and what banks decide to offer.
The interest compounds at intervals set by the bank — usually daily, monthly, or quarterly. Compounding means you earn interest on your interest, so your balance grows faster than it would with straightforward interest. At maturity, you receive your original deposit plus all the interest earned.
What happens when your CD reaches maturity
When your CD term ends, the bank sends you a notice — usually 10 to 14 days before maturity — telling you what will happen next. You have several choices: withdraw the money, 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 term at the current rate. 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 important date if you want to do something different.
When you withdraw at maturity, there is no penalty. You get your full principal plus all interest earned. The bank reports the interest to the IRS on a Form 1099-INT, and you owe federal income tax on that interest in the year you receive it, even though you did not actually withdraw the money until maturity.
Early withdrawal penalties and when they explore
If you need your money before the maturity date, you can withdraw it — but the bank will charge an early withdrawal penalty. This penalty is a set number of months of interest that you forfeit. A CD with a one-year term might have a penalty of three months of interest, while a five-year CD might have a penalty of six months or a year.
The penalty is deducted from your interest earnings first. If your earnings are smaller than the penalty, the bank takes the difference from your principal. For example, if you earned $200 in interest but the penalty is $300, you get back your original deposit minus $100.
Some banks offer no-penalty CDs that let you withdraw early without a penalty, but they pay lower interest rates to offset that flexibility. These are worth considering if you are uncertain whether you will need the money, but they defeat the main purpose of a CD — locking in a higher rate in exchange for commitment.
CD laddering: a strategy to balance rate and access
One way to get higher CD rates while keeping some money accessible is CD laddering. Instead of putting all your money into one five-year CD, you split it into five one-year CDs. Each year, one CD matures and you can withdraw the money, reinvest it, or let it renew.
This strategy lets you take advantage of rising rates without being locked in for years. If rates go up, you can reinvest your maturing CD at the new higher rate. If rates fall, you still have four CDs earning the old higher rate. The trade-off is that you earn less interest overall than you would with a single five-year CD, because the shorter-term CDs pay less.
Laddering works best when you have a substantial amount to invest — at least $5,000 to $10,000 — and you are comfortable managing multiple CDs. Many people use it to balance the safety and predictability of CDs with the flexibility they need for their actual finances.
How CD rates compare to other savings options
CDs typically pay more than regular savings accounts or money market accounts at the same bank, but less than you might earn from stocks or bonds over the long term. The exact difference varies by institution and market conditions.
A regular savings account at a large bank might pay 0.01 percent, while a high-yield savings account at an online bank might pay 4.0 to 5.0 percent. A one-year CD at that same online bank might pay 4.5 to 5.2 percent — higher than the savings account, but not dramatically so. The main advantage of the CD is that the rate is locked in and may provide, whereas savings account rates can change at any time.
If you need the money within a year or two and want to avoid the stock market, a CD is a straightforward choice. If you will not need the money for five or ten years, you might earn more from a diversified investment portfolio, but you also accept the risk of losses. CDs offer no growth potential beyond the stated rate, but they also offer no risk of losing your principal.
Where to open a CD and what to compare
You can open a CD at any bank or credit union. Large national banks, regional banks, online banks, and credit unions all offer them. Online banks typically pay higher rates than brick-and-mortar banks because they have lower overhead costs.
When comparing CDs, look at the annual percentage yield (APY), the term length, the minimum deposit required, and the early withdrawal penalty. The APY is the rate you will actually earn when compounding is included — it is always equal to or higher than the stated interest rate. A CD with a slightly lower APY but a lower early withdrawal penalty might be better for you than one with a higher rate but a steep penalty.
Check whether the bank or credit union is FDIC or NCUA insured. If you have more than $250,000 to invest, you can open CDs at multiple institutions to keep all your money insured. Some people also use brokered CDs, which are CDs sold through investment firms, but these carry additional complexity and risk that standard bank CDs do not.
Tax treatment of CD interest
The interest you earn on a CD is taxable income in the year you receive it, even if you do not withdraw the money. The bank reports this interest to you and the IRS on a Form 1099-INT, usually by January 31 of the following year.
If your CD is in a tax-advantaged account like a traditional IRA or Roth IRA, the tax treatment is different. Interest in a traditional IRA is tax-deferred, and interest in a Roth IRA is tax-free if you follow the withdrawal rules. Many people use CDs inside IRAs to get a may provide return without the tax burden of a regular CD.
If you are in a high tax bracket, the after-tax return on a CD might be lower than you expect. A 5 percent CD pays 5 percent only if you owe no taxes on it. If you are in the 24 percent federal tax bracket, your after-tax return is closer to 3.8 percent. This is still a real return, but it is worth calculating before you commit your money.
Frequently Asked Questions
Can I withdraw money from a CD before it matures?
Yes, but you will pay an early withdrawal penalty set by the bank. The penalty is usually a certain number of months of interest. If the penalty exceeds your earnings, the bank deducts the difference from your principal. Some banks offer no-penalty CDs that let you withdraw without a fee, but they pay lower interest rates.
What happens if the bank fails while I have a CD?
Your CD is protected up to $250,000 by the FDIC if the bank is FDIC insured, or by the NCUA if it is a credit union. If the bank fails, the FDIC or NCUA takes over and either transfers your CD to another institution or pays you out directly. Your money and accrued interest are safe.
Can I move a CD to another bank before it matures?
You can withdraw the money and move it, but you will pay the early withdrawal penalty. You cannot transfer a CD directly to another bank without withdrawing it first. If you want to move your money, compare the penalty cost against the rate difference at the new bank to see if it makes financial sense.
Do I have to pay taxes on CD interest?
Yes, CD interest is taxable income in the year you receive it, reported on Form 1099-INT. You owe federal income tax and possibly state income tax on the interest. The exception is a CD held inside a traditional IRA (tax-deferred) or Roth IRA (tax-free if withdrawal rules are met).
What is the difference between a CD and a savings account?
A CD locks your money away for a set term and pays a fixed, higher interest rate. A savings account lets you withdraw anytime but pays a lower rate that can change. CDs are better if you will not need the money soon and want a may provide return. Savings accounts are better if you need flexibility and access to your cash.
