A Certificate of Deposit Is a Savings Account That Locks Your Money Away for a Set Time

A certificate of deposit (CD) is a savings product offered by banks and credit unions where you give them money to hold for a fixed period—usually three months to five years. In exchange, they pay you a higher interest rate than a regular savings account. The catch is that you agree not to touch the money until the term ends, or you pay a penalty.

The bank uses your money during that time and pays you interest on top of your original deposit. When the term is up, you get back your full deposit plus the interest earned. CDs are considered very safe because they are insured by the Federal Deposit Insurance Corporation (FDIC) up to $250,000 per account holder per bank.

Key Takeaways

  • You deposit money for a fixed term (three months to five years) and cannot withdraw it without paying a penalty until that term ends.
  • Banks pay higher interest rates on CDs than on regular savings accounts because your money is locked in.
  • Your deposit and interest are insured by the FDIC up to $250,000, making CDs a low-risk way to save.
  • When your CD matures, you can withdraw the money, renew it for another term, or move it elsewhere.
  • Early withdrawal penalties vary by bank but typically cost you some or all of the interest you earned.

How Interest Rates and Terms Work

The interest rate on a CD is fixed when you open it, meaning it will not change during your term. A three-month CD might pay 4.5 percent, while a five-year CD at the same bank might pay 5.2 percent. Longer terms usually come with higher rates because the bank has your money for longer and can lend it out for bigger projects.

Interest compounds on most CDs, which means you earn interest on your interest. If you deposit $5,000 in a one-year CD at 5 percent annual interest, you will have $5,250 at the end of the year. The exact amount depends on how often the bank compounds the interest—daily, monthly, or quarterly—so read the disclosure carefully.

The rate environment matters too. When interest rates in the economy are high, banks offer higher CD rates to attract deposits. When rates are low, CD rates drop as well. You cannot negotiate the rate; it is set by the bank.

What Happens When Your CD Matures

When your term ends, your CD reaches maturity. At that point, the bank gives you a window—usually 7 to 10 days—to decide what to do with the money. You have three main options: withdraw the cash, renew the CD for another term at the current rate, or move the money to a different product.

If you do nothing during that window, many banks automatically renew your CD for another term at whatever rate they are currently offering. This can work in your favor if rates have gone up, but it locks you in again if rates have fallen. Read your CD agreement to see what your bank does by default.

Some banks offer a grace period of a few days after maturity where you can withdraw without penalty. After that window closes, early withdrawal penalties kick in again if you want your money out.

Early Withdrawal Penalties and When They explore

If you need your money before the CD matures, you can withdraw it, but you will pay a penalty. The penalty is usually a certain number of months of interest. A CD with a three-month penalty means you lose three months' worth of the interest you earned. If you earned $100 in interest and the penalty is three months, you might lose $25.

Some banks calculate the penalty differently—as a percentage of your deposit or a flat fee. Always ask what the early withdrawal penalty is before you open a CD. It is listed in the disclosure document the bank gives you.

The penalty applies only if you withdraw before maturity. Once your CD matures and you withdraw the money, there is no penalty. This is why CDs work best for money you know you will not need for the full term.

Why People Use CDs Instead of Regular Savings Accounts

A regular savings account at most banks pays very little interest—often less than 0.5 percent. A CD at the same bank might pay 4 or 5 percent. Over time, that difference adds up. On $10,000, the difference between 0.5 percent and 5 percent is $450 per year.

CDs also appeal to people who want to remove temptation. Because the money is locked away and you pay a penalty to touch it, you are less likely to spend it on something else. This makes CDs a good tool for saving toward a specific goal—a down payment, a car, or an emergency fund you are building up.

The safety factor matters too. Your deposit is insured by the FDIC, so even if the bank fails, your money up to $250,000 is protected. This makes CDs much safer than investing in stocks or bonds, where the value can go down.

CD Ladders and How to Use Them

Some savers use a strategy called a CD ladder to balance safety with access to their money. Instead of putting all your savings into one five-year CD, you split it among several CDs with different maturity dates. For example, you might buy five one-year CDs, each with $2,000. One matures every year, giving you access to $2,000 without penalty.

When the first CD matures after one year, you can withdraw the money or reinvest it in a new five-year CD. This way, you always have some money coming available while still locking most of it away for higher rates. Ladders work best when you have a larger amount to split up and you do not need all the money at once.

Frequently Asked Questions

Can I withdraw money from a CD before it matures?

Yes, but you will pay an early withdrawal penalty set by your bank. The penalty is usually several months of interest. Once your CD matures, you can withdraw without penalty. Check your bank's disclosure to see the exact penalty before you open the CD.

What is the difference between a CD and a savings account?

A savings account lets you withdraw money anytime with no penalty, but it pays very low interest. A CD locks your money for a set term and pays higher interest, but you pay a penalty if you withdraw early. CDs are better for money you will not need soon; savings accounts are better for emergency funds.

Are CDs safe if the bank fails?

Yes. The FDIC insures CDs up to $250,000 per account holder per bank. If your bank fails, the FDIC will return your deposit and interest. This protection applies as long as your total deposits at that bank do not exceed $250,000.

What happens if I do nothing when my CD matures?

Most banks automatically renew your CD for another term at their current rate. This happens during a grace period, usually 7 to 10 days after maturity. If you do not want to renew, contact your bank during that window to withdraw or move the money.

Do I pay taxes on CD interest?

Yes. The interest you earn on a CD is taxable income in the year you earn it. Your bank will send you a 1099-INT form at tax time showing how much interest you earned. You report this on your tax return.
