What a Certificate of Deposit Is

A certificate of deposit (CD) is an agreement between you and a bank or credit union: you give them a fixed amount of money for a set period of time, and they pay you a fixed interest rate in return. You cannot touch that money during the term without paying a penalty. In exchange for locking your cash away, the bank pays you more interest than you would earn in a regular savings account.

CDs are FDIC-insured at most banks and NCUA-insured at credit unions, meaning your deposit is protected up to $250,000 if the institution fails. This makes them one of the safest places to put money that you know you will not need for a while.

Key Takeaways

  • You deposit a lump sum for a fixed term (typically three months to five years) and receive a may provide interest rate that does not change.
  • Withdrawing money before the term ends costs you an early withdrawal penalty, usually a few months' worth of interest.
  • CD rates are higher than savings accounts but lower than stock market returns, and they carry no market risk.
  • The interest you earn is taxable income, reported to the IRS on a 1099-INT form if it exceeds $10.
  • CDs work best for money you will not need for a specific period and want to protect from market swings.

How the Interest Rate and Term Work Together

When you open a CD, the bank locks in an interest rate for the entire term. That rate does not move, even if the Federal Reserve raises or lowers rates while your CD is open. If you buy a one-year CD at 4.5 percent, you earn 4.5 percent for the full year, regardless of what happens in the market.

Terms range from as short as three months to as long as ten years, though one, two, and five-year CDs are most common. Longer terms usually pay higher rates because the bank gets to hold your money longer. A five-year CD might pay 4.8 percent while a one-year CD pays 4.2 percent. You choose the term based on when you know you will need the money.

Interest compounds on a schedule set by the bank—usually daily, monthly, or quarterly. Compounding means the interest you earn also earns interest. The more often it compounds, the slightly more you end up with, though the difference is usually small.

What Happens When Your CD Matures

When the term ends, your CD matures. The bank deposits your original deposit plus all the interest you earned into your account. You then have a choice window—usually seven to ten days—to decide what to do with the money.

You can withdraw it, move it to another account, or roll it into a new CD. If you do nothing during that window, most banks automatically roll the money into a new CD with the same term at whatever the current rate is. That new rate may be higher or lower than your original one. If you do not want to renew, you need to act before the window closes or you will be locked in again.

Early Withdrawal Penalties and When They Apply

If you need your money before the CD matures, the bank will let you take it—but you pay an early withdrawal 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 $10,000 CD earning 4 percent annually, that penalty would be about $10.

Some CDs have steeper penalties—six months or even a year of interest. High-yield CDs sometimes have lower penalties to make them more attractive. Before you open a CD, read the disclosure form to see exactly what the penalty is. If you think there is any chance you will need the money early, factor that penalty into your decision.

A few banks offer no-penalty CDs that let you withdraw without a penalty, though they pay lower interest rates in exchange. These work well if you want the safety of a CD but are not certain about your timeline.

How CD Interest Is Taxed

The interest you earn on a CD is ordinary income and is taxed at your regular income tax rate. If you earn $500 in CD interest during the year, that $500 counts as taxable income on your federal return. You pay tax on the interest even if you do not withdraw it—the bank counts it as earned when the CD matures or when interest is credited, depending on the CD type.

If your CD interest exceeds $10 in a calendar year, the bank sends you a 1099-INT form by January 31 reporting the amount. You use this form to report the interest on your tax return. If you have CDs at multiple banks, you may receive multiple 1099-INT forms.

One strategy some people use is holding CDs in tax-advantaged accounts like IRAs, where the interest grows tax-free until you withdraw it. This only works if you have contribution room in those accounts.

CD Ladders and How They Help

A CD ladder is a strategy where you buy multiple CDs with different maturity dates instead of one large CD. For example, you might buy five $2,000 CDs with one, two, three, four, and five-year terms. Each year, one CD matures, giving you access to money without paying a penalty.

Ladders solve two problems: they give you regular access to cash, and they let you take advantage of higher long-term rates without locking all your money away for years. When the first CD matures, you can roll it into a new five-year CD, keeping the ladder going. This approach works well if you have a lump sum to invest and want both safety and flexibility.

CDs Versus Savings Accounts and Money Market Accounts

A regular savings account has no term and no penalty for withdrawal, but it pays much less interest—often under 0.5 percent. A money market account sits in the middle: it pays more than savings but less than CDs, and you can withdraw money without penalty, though there are limits on how often you can withdraw.

CDs pay the most because you give up access. If you know you will not need money for a year or more, a CD almost always pays more. If you might need it sooner, the early withdrawal penalty could wipe out all your interest, making a savings account the safer choice. Money market accounts work well if you want higher interest but need flexibility.

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 few months of interest. Some banks offer no-penalty CDs that let you withdraw without a fee, though they pay lower rates. Check the disclosure before opening a CD to know the exact penalty.

What happens if I do not withdraw my money when the CD matures?

Most banks automatically roll your CD into a new one with the same term at the current rate. You have a grace period—usually seven to ten days—to withdraw or move the money if you do not want to renew. If you miss that window, you are locked in again at the new rate.

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

Yes. CDs at banks are insured by the FDIC up to $250,000 per account holder per bank. CDs at credit unions are insured by the NCUA up to the same amount. If the institution fails, your money and interest are protected.

Do I pay taxes on CD interest before or after the CD matures?

You owe tax on the interest in the year it is earned, even if you do not withdraw it. The bank reports it on a 1099-INT form if it exceeds $10. You report this on your tax return whether or not you have actually received the money.

Is a CD ladder worth the effort?

A ladder is worth it if you have a large lump sum and want both higher rates and regular access to cash. It takes more work to set up and track, but it solves the problem of being locked into one maturity date. For smaller amounts or shorter time horizons, a single CD or savings account may be simpler.
