CD stands for Certificate of Deposit, and it's a savings product where you lock money away for a set period in exchange for a fixed interest rate

A Certificate of Deposit is a contract 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 time period. In return, the bank pays you a higher interest rate than you'd get in a regular savings account. That rate is locked in from day one and doesn't change, even if the bank's rates drop.

The time period is called the term, and it's part of the deal you make upfront. Common terms are three months, six months, one year, two years, or five years. When the term ends—the maturity date—you get your original money back plus the interest earned. Then you decide what to do next: withdraw it, spend it, or roll it into a new CD.

The tradeoff is straightforward: you give up access to your money for a while, and the bank gives you a better rate. If you need the money before the maturity date, most banks will let you withdraw it early, but they charge a penalty—usually a few months' worth of interest. That penalty is the cost of breaking the agreement.

Key Takeaways

  • A CD is a savings account where you lock money in for a set term—typically three months to five years—in exchange for a fixed interest rate higher than a regular savings account.
  • Your interest rate is locked in on day one and does not change, regardless of what happens to the bank's other rates during your term.
  • When your term ends, you receive your original deposit plus all interest earned, and you can then withdraw the money or open a new CD.
  • Withdrawing money before the maturity date triggers an early withdrawal penalty, usually equal to a few months of the interest you would have earned.
  • CDs are insured by the FDIC up to $250,000 per depositor per bank, so your principal is protected even if the bank fails.

How the interest rate and term work together

The interest rate on a CD is fixed, meaning it stays the same for the entire term. If you open a one-year CD at 4.5 percent, you'll earn 4.5 percent for all twelve months, even if the bank raises its rates to 5 percent next month. This is different from a savings account, where the rate can change at any time.

The term you choose affects the rate you receive. Longer terms usually come with higher rates because the bank gets to hold your money longer. A five-year CD might pay 4.8 percent while a three-month CD pays 3.2 percent. The bank is betting you won't need the money, and it rewards you for that certainty.

When your term ends, the bank sends you a notice—usually 10 to 14 days before maturity. At that point, you have a few options: withdraw everything, let the bank automatically roll it into a new CD at the current rate, or move the money elsewhere. If you do nothing and the bank auto-renews, you're locked in again at whatever rate they're offering at that moment, which could be higher or lower than before.

What happens if you need the money early

Most banks allow early withdrawal from a CD, but they charge a penalty for breaking the agreement. The penalty is usually expressed as a number of months of interest. A common penalty might be three months of interest, meaning if you were earning $50 a month, you'd lose $150 by withdrawing early.

The penalty comes out of your interest earnings first. If you haven't earned enough interest yet to cover the penalty, the bank takes the difference from your principal—your original deposit. This is rare with longer terms, but it can happen with very short CDs if you withdraw in the first few weeks.

Some banks offer no-penalty CDs, which let you withdraw your money without a penalty, though the interest rate is usually lower than a standard CD. These are worth considering if you're uncertain about needing the money, but they defeat some of the purpose of locking money away for a higher rate.

CD laddering: a strategy for accessing your money

Because CDs lock your money away, many people use a strategy called CD laddering to keep some cash accessible while still earning higher rates. Here's how it works: instead of putting all $10,000 into one five-year CD, you split it into five $2,000 CDs with terms of one, two, three, four, and five years.

Each year, one CD matures and you can withdraw that money or reinvest it. After five years, you've had access to some of your money every year, but you've also earned the higher rates that longer terms offer. This approach requires planning and discipline, but it solves the real problem many people face: wanting both safety and access.

FDIC insurance and what it covers

CDs are insured by the Federal Deposit Insurance Corporation (FDIC) up to $250,000 per depositor per bank. This means if the bank fails, the FDIC will return your money—principal plus accrued interest—up to that limit. You don't need to do anything to get this protection; it's automatic.

The $250,000 limit applies per bank, not per CD. If you have two CDs at the same bank totaling $300,000, only $250,000 is insured. If you want to insure more than $250,000, you'd need to split your money across different banks. Some people use this strategy when they have large sums to invest.

How CDs compare to savings accounts and money market accounts

A regular savings account gives you full access to your money anytime, but the interest rate is usually much lower—often under 1 percent. A CD locks your money away but pays more—currently 4 to 5 percent depending on the term and the bank. The tradeoff is access versus rate.

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 withdrawal privileges without a penalty. If you need some access but want a better rate than savings, a money market account might fit better than a CD.

The right choice depends on your situation. If you have money you won't need for a year or more, a CD usually makes sense. If you might need it sooner, a savings account or money market account is safer because you won't face a penalty.

Frequently Asked Questions

Can I withdraw money from a CD before it matures?

Yes, but you'll pay an early withdrawal penalty, usually equal to a few months of interest. The exact penalty depends on the bank and the CD term. Some banks offer no-penalty CDs that let you withdraw without a fee, though the interest rate is typically lower.

What happens when my CD reaches maturity?

The bank will notify you before the maturity date. You can then withdraw your money, open a new CD at the current rate, or move the funds elsewhere. If you do nothing, many banks automatically renew your CD at their current rate, which may be higher or lower than your previous rate.

Is my money safe in a CD if the bank fails?

Yes, up to $250,000. The FDIC insures CDs automatically, so if the bank fails, you'll receive your principal plus accrued interest up to that limit. If you have more than $250,000, you can spread it across multiple banks to insure the full amount.

Why would I choose a CD over a regular savings account?

CDs pay significantly higher interest rates because you agree to lock your money away for a set period. If you have money you won't need for months or years, a CD lets you earn more. The tradeoff is that you can't access the money without paying a penalty.

Do I pay taxes on CD interest?

Yes. The interest you earn on a CD is taxable income in the year you earn it, even if you don't withdraw the money. The bank will send you a 1099-INT form at tax time showing how much interest you earned. This is true whether the CD is in a regular account or a retirement account like an IRA.
