A CD locks your money away for a set time in exchange for a may provide interest rate
A certificate of deposit (CD) is a savings product where you give a bank a lump sum of money and agree not to touch it for a fixed period—typically three months to five years. In return, the bank pays you a fixed interest rate that is usually higher than what you'd earn in a regular savings account. When the term ends, you get your original money back plus the interest earned.
The trade-off is straightforward: you lose access to your cash for the duration. If you withdraw the money early, the bank charges a penalty that reduces your earnings or eats into your principal. This penalty structure is what makes CDs different from savings accounts, where you can withdraw whenever you want.
CDs are insured by the Federal Deposit Insurance Corporation (FDIC) up to $250,000 per depositor, per bank. This means if the bank fails, your money is protected up to that limit. That protection applies to each CD separately if you hold multiple CDs at the same institution.
Key Takeaways
- You deposit a fixed amount of money for a set term (three months to five years) and receive a may provide interest rate that does not change.
- Withdrawing money before the term ends triggers an early withdrawal penalty, which typically ranges from three months to one year of interest.
- CDs are FDIC-insured up to $250,000 per depositor per bank, making them a low-risk savings option.
- Interest rates on CDs vary by bank, term length, and current economic conditions, so comparing offers across institutions is worth your time.
- A CD makes sense if you have money you won't need for several months or years and want a may provide return without stock market risk.
How interest rates and term lengths work together
The longer you lock your money away, the higher the interest rate the bank typically offers. A three-month CD might pay 4.5%, while a five-year CD at the same bank might pay 5.2%. The bank is compensating you for giving up access to your cash for a longer period.
Interest rates on CDs change based on what the Federal Reserve does with its benchmark interest rate. When the Fed raises rates, new CDs issued by banks tend to offer higher rates. When the Fed cuts rates, new CD rates fall. If you already own a CD, your rate is locked in and does not change, even if market rates drop.
You can find current CD rates by visiting bank websites, using rate-comparison sites, or calling banks directly. Rates vary significantly—a high-yield online bank might offer 4.8% on a one-year CD while a traditional brick-and-mortar bank offers 3.2% for the same term. Shopping around can add hundreds of dollars to your earnings over the life of the CD.
What happens when your CD matures
When the term ends, your CD reaches maturity. At that point, the bank deposits your principal plus accrued interest into your account. Most banks give you a grace period—usually seven to ten days—during which you can decide what to do next without penalty.
You have three options: let the bank automatically roll the money into a new CD at the current rate (called auto-renewal), withdraw the funds, or move the money to a different account. If you do nothing and the bank auto-renews, you are locked in again at whatever rate the bank is offering at that time, which may be lower than your original rate.
To avoid being auto-renewed at an unfavorable rate, contact your bank before the maturity date and tell them what you want to do. Some banks require written notice; others accept phone or online instructions. Check your CD agreement or call customer service to confirm the process at your specific bank.
Early withdrawal penalties and when they explore
If you need your money before the CD matures, you can withdraw it, but the bank will charge a penalty. The penalty is usually expressed as a number of months of interest—for example, "three months of interest" or "six months of interest." On a $10,000 CD earning 4.5% annually, a three-month penalty would cost you roughly $112.50.
Some banks calculate the penalty differently: they may subtract a flat fee or a percentage of your principal. Read your CD agreement to understand exactly how your bank calculates the penalty. The penalty comes out of your earnings first; if the penalty exceeds your interest, it reduces your principal.
A few banks offer no-penalty CDs, which let you withdraw your money early without a penalty, though usually at a lower interest rate than a traditional CD. These are worth considering if you think you might need the cash before maturity, though the rate trade-off is significant.
CDs versus savings accounts and money market accounts
A regular savings account has no term and no penalty for withdrawal, but the interest rate is usually much lower—often under 0.5% at traditional banks. You have complete flexibility but earn very little. A CD sacrifices flexibility for a higher, may provide rate.
A money market account sits between the two: it typically pays more than a savings account but less than a CD, and it usually allows a limited number of withdrawals per month without penalty. Money market accounts are good if you want some growth but need occasional access to your cash.
If you have money you will not need for at least three to six months, a CD almost always pays more than a savings account at the same bank. The question is whether the higher rate is worth locking your money away. If you might need the cash sooner, a savings account or money market account is safer.
Tax treatment and how interest is reported
Interest earned on a CD is taxable income in the year it is earned, even if you do not withdraw the money. The bank will send you a Form 1099-INT at the end of the tax year showing how much interest you earned. You report this on your federal tax return.
If you withdraw money early and pay a penalty, you can deduct the penalty from your interest income on your tax return. This reduces your taxable income slightly, but it does not eliminate the fact that you earned less than you expected.
If you hold a CD in a tax-advantaged account like an IRA, the interest is not taxed until you withdraw from the account, depending on the type of IRA. Talk to a tax professional if you are using CDs as part of a retirement strategy.
Where to find CDs and how to compare them
You can open a CD at any bank or credit union. Online banks typically offer higher rates than traditional banks because they have lower overhead costs. Credit unions sometimes offer competitive rates to their members. You can also buy CDs through a brokerage account, though those work slightly differently and may have different FDIC protections.
To compare CDs, list the term you want (three months, one year, five years, etc.) and then check rates at five to ten institutions. Write down the rate, the term, the minimum deposit required, and the early withdrawal penalty. A difference of 0.5% between banks might not sound like much, but on a $25,000 CD over five years, it adds up to hundreds of dollars.
Some banks offer promotional rates for new customers or for large deposits. These rates are real but temporary—they may drop after a few months. If you are comparing, make sure you are looking at the rate that will explore to your specific deposit amount and account type.
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 twelve months of interest, though some banks charge a flat fee or percentage of principal. A few banks offer no-penalty CDs at a lower rate. Check your CD agreement to see exactly what your bank charges.
What is the minimum amount I need to open a CD?
Minimum deposits vary by bank and CD type. Many banks require $500 to $1,000 to open a CD, while some online banks allow deposits as low as $100. A few banks have no minimum. Check the specific bank's website or call to confirm the minimum for the CD you are interested in.
Is my money safe in a CD?
Yes, as long as your deposit is under $250,000 and the bank is FDIC-insured. The FDIC protects your principal and interest if the bank fails. Check the bank's website or the FDIC's bank search tool to confirm it is FDIC-insured before you open an account.
What happens if interest rates drop after I buy a CD?
Your rate stays the same for the entire term. You are locked in at the rate you agreed to when you opened the CD. This is actually an advantage if rates fall—you keep earning the higher rate while new CDs pay less.
Should I buy a CD or keep money in a savings account?
If you will not need the money for at least three to six months, a CD usually pays significantly more. If you might need it sooner, a savings account gives you flexibility without penalty. Consider how long you can afford to lock the money away before deciding.
