A CD is a savings account where you lock up your money for a set time in exchange for a may provide interest rate
A certificate of deposit (CD) is an agreement between you and a bank. You give the bank a lump sum of money—say $5,000—and agree not to touch it for a specific period: three months, six months, one year, five years, or whatever term you choose. In return, the bank pays you a fixed interest rate that is higher than what you'd earn in a regular savings account. When the term ends, you get your original money back plus the interest.
The trade-off is simple: you lose access to your cash for the duration. If you withdraw the money early, the bank charges a early withdrawal penalty—usually a few months' worth of interest, though the exact amount depends on the CD and the bank. You know the interest rate upfront and it does not change, so there is no guessing about what you will earn.
CDs are insured by the Federal Deposit Insurance Corporation (FDIC) up to $250,000 per depositor, per bank. That means if the bank fails, your money is protected by the federal government up to that limit.
Key Takeaways
- You deposit a fixed amount of money and agree not to withdraw it until the CD matures, typically in exchange for a higher interest rate than a regular savings account.
- 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.
- Withdrawing money before the maturity date triggers an early withdrawal penalty, usually equal to a few months of interest.
- Your deposit is FDIC-insured up to $250,000, so your principal is protected if the bank fails.
- CDs work best if you have money you will not need for several months or years and want a may provide return.
How interest rates and terms work together
CD interest rates vary by bank and by term length. Generally, the longer you lock your money away, the higher the rate the bank will offer you. A three-month CD might pay 4.5% annual interest, while a five-year CD from the same bank might pay 5.2%. Rates also shift with the broader economy—when the Federal Reserve raises its benchmark rate, CD rates tend to rise a few weeks later. When rates fall, CD rates fall too.
The interest is usually compounded daily or monthly, meaning you earn interest on your interest. The bank calculates how much you will have at maturity and tells you that number before you commit. There are no surprises.
Some banks offer no-penalty CDs, which let you withdraw your money early without losing interest. The catch is that these CDs pay lower rates than standard CDs, because the bank is taking on more risk. You pay for the flexibility in lower earnings.
When a CD matures and what happens next
When your CD reaches its maturity date, the bank deposits your principal plus interest into your account—usually a linked checking or savings account you specify when you open the CD. You can then withdraw the money, move it to another CD, or leave it in your regular account.
Many banks have an auto-renewal period, typically 7 to 10 days after maturity. If you do not withdraw or move your money during that window, the bank automatically rolls it into a new CD with the same term at whatever the current rate is. The new rate may be higher or lower than what you just earned. If you do not want to renew, you must contact the bank or withdraw the funds before the auto-renewal kicks in.
Read the CD terms carefully when you open it, because auto-renewal rules vary by bank. Some banks notify you by mail or email before renewal; others do not.
CD laddering: spreading your money across multiple terms
One strategy people use to balance higher rates with regular access to cash is called 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 spend it. You still earn higher rates than a savings account, but you are not locked in for five years.
For example: you have $10,000. You open five $2,000 CDs with maturity dates one year apart. Year one, $2,000 matures. Year two, another $2,000 matures. And so on. This way you have regular access to portions of your money without paying early withdrawal penalties.
Laddering works best when rates are stable or rising. If rates are falling, you may regret locking money into longer terms at lower rates.
Early withdrawal penalties and when they apply
If you need your money before the CD matures, you can withdraw it—but the bank will charge you a penalty. The penalty is usually expressed as a number of months of interest. A CD with a three-month penalty means you lose three months' worth of the interest you would have earned. On a $5,000 CD paying 5% annual interest, that is roughly $62.50.
Some banks calculate the penalty differently: they may charge a flat fee or a percentage of your deposit. Always ask the bank what the early withdrawal penalty is before you open the CD. It is part of the contract.
The penalty comes out of your interest earnings first. If you have not earned enough interest to cover the penalty, the bank takes the difference from your principal. In rare cases, you could end up with less money than you deposited.
CDs versus savings accounts and money market accounts
A regular savings account offers flexibility—you can withdraw money anytime without penalty—but the interest rate is usually much lower, often under 1% annual interest. A CD locks you in but pays more, sometimes 4% to 5% or higher depending on the bank and term.
A money market account sits in the middle. It typically pays more than a savings account but less than a CD, and it gives you limited check-writing or debit card access without locking your money away. Money market accounts are FDIC-insured like CDs, but the rate is variable, meaning it can change at any time.
Choose a CD if you have money you will not need for months or years and want the highest may provide rate. Choose a savings account if you need quick access. Choose a money market account if you want a middle ground.
Who should use CDs and who should not
CDs work well for people saving for a specific goal with a known timeline: a down payment on a house in two years, a car purchase in 18 months, or a vacation in six months. They also work for people who want to lock in a good rate before rates fall, or who simply do not trust themselves to leave money alone in a regular savings account.
CDs are not ideal if you might need the money unexpectedly, because the early withdrawal penalty can eat into your returns. They are also not ideal if you think interest rates will rise significantly in the near future—you will be stuck earning a lower rate for the full term. And if inflation is high, a CD rate that looks good today might not keep pace with rising prices over time.
CDs are also not an investment vehicle. You are not buying stock or betting on market performance. You are simply earning a may provide, modest return on cash you are not using right now.
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 typically a few months of interest, though it varies by bank and CD term. Some banks offer no-penalty CDs that let you withdraw without losing interest, but these pay lower rates than standard CDs.
What happens if the bank fails?
Your CD is protected by FDIC insurance up to $250,000. If the bank fails, the FDIC pays you your principal plus any interest earned up to the maturity date, even if the bank no longer exists. You do not need to do anything—the insurance is automatic.
Can I move my CD to a different bank?
You can withdraw your money and open a CD at another bank, but you will pay the early withdrawal penalty at your current bank. You cannot transfer a CD directly to another bank without closing it first.
Do I pay taxes on CD interest?
Yes. CD interest is taxable income. The bank will send you a 1099-INT form at the end of the year showing how much interest you earned, and you report that on your tax return. Some people use CDs in retirement accounts (like IRAs) to defer taxes on the interest.
What if I do not withdraw my money when the CD matures?
Most banks automatically renew your CD into a new term at the current rate if you do not withdraw or move the money within the grace period (usually 7 to 10 days after maturity). Check your bank's renewal policy so you know when to act if you want to withdraw or move your money instead.
