A certificate of deposit is a savings product where you lend money to a bank for a fixed period in exchange for a may provide interest rate
A certificate of deposit (CD) is a contract between you and a bank or credit union. You give them a sum of money — called the principal — and agree to leave it untouched for a specific length of time, called the term. In return, the bank pays you interest at a rate that is locked in from the start. When the term ends, you get your principal back plus the interest you earned.
CDs are different from regular savings accounts. With a savings account, you can withdraw money whenever you want, but the interest rate is usually low and can change. With a CD, the interest rate is higher and fixed, but you cannot touch the money without a penalty. The bank knows exactly how long it will hold your money, so it offers better terms.
CDs come in different term lengths. Common terms are three months, six months, one year, two years, and five years. The longer the term, the higher the interest rate usually is. A one-year CD will pay more interest than a three-month CD at the same bank.
Key Takeaways
- You deposit a fixed amount of money for a set period and cannot withdraw it without paying a penalty until the term ends.
- The interest rate on a CD is locked in when you open it and does not change, even if the bank's rates go up or down.
- Longer CD terms typically offer higher interest rates than shorter ones at the same institution.
- When a CD matures, you receive your original deposit plus all the interest earned, and you can then choose to open a new CD or move the money elsewhere.
- CDs are insured by the FDIC (if at a bank) or NCUA (if at a credit union) up to $250,000 per depositor per institution.
How interest rates and terms work together
The interest rate you receive depends on two things: what the bank is offering at that moment, and how long your term is. Banks set their CD rates based on what the Federal Reserve is doing and what other banks are charging. If you shop around, you will find different rates at different banks for the same term length.
The term length matters more than most people realize. A five-year CD might pay 4.5 percent annually, while a six-month CD at the same bank might pay only 2.0 percent. That difference adds up fast if you have a large deposit. However, the trade-off is that you cannot access your money for five years without losing some of the interest you earned.
Interest on a CD can be paid to you in different ways. Some banks pay interest monthly or quarterly. Others hold all the interest until the CD matures. Some CDs allow you to add the interest to the principal so it earns interest too (called compounding). Ask your bank how interest is handled before you open a CD.
What happens when your CD reaches maturity
When your CD term ends, the bank sends you a notice — usually 10 to 30 days before the maturity date — telling you what happens next. On the maturity date, your CD stops earning interest. At that point, you have choices.
You can withdraw the money and take it somewhere else. You can open a new CD at the same bank, often at a new rate that reflects current market conditions. You can move the money to a savings account. Or you can do nothing, and many banks will automatically roll your CD into a new one at the current rate — but read the fine print, because some banks charge a fee for this automatic renewal.
If you withdraw money before the maturity date, you will pay an early withdrawal penalty. This penalty is usually a certain number of months of interest. For example, a one-year CD might have a penalty of three months of interest. If you withdraw after six months, you lose three months' worth of the interest you earned. The bank will tell you the penalty amount when you open the CD.
Where CDs fit in your savings strategy
CDs work best for money you know you will not need for a while. If you have an emergency fund, a CD is not the right place for it because you need quick access. But if you have money saved for a goal that is two or three years away — a down payment on a house, a car, a vacation — a CD can help that money grow safely.
CDs are also useful if you want to lock in a good interest rate. If rates are high right now and you think they might drop, opening a CD lets you keep that rate for the entire term. You are protected from rate cuts, but you are also locked out if rates rise.
Some people use a strategy called a CD ladder. Instead of putting all their money in one CD with a five-year term, they open five CDs with one-year terms, each maturing in a different year. As each CD matures, they can reinvest in a new five-year CD. This way, they get some of the higher rates of longer terms while still having access to some money each year.
FDIC insurance and safety
Money in a CD at a bank is protected by FDIC insurance up to $250,000 per depositor per bank. This means if the bank fails, the federal government will pay you back up to that amount. If you have a CD at a credit union, it is protected by NCUA insurance, also up to $250,000.
This protection applies to the principal plus any interest earned. So if you deposit $100,000 in a CD and earn $5,000 in interest, the total $105,000 is covered as long as it is under the $250,000 limit at that one institution.
If you want to protect more than $250,000, you can open CDs at different banks. Each bank's CDs are insured separately. You can also open a CD in your name alone and another in joint names with a spouse — these are counted separately for insurance purposes.
How CDs compare to other savings options
Different savings products serve different purposes depending on when you need access to your money and what interest rate matters most to you. The table below shows how CDs stack up against the most common alternatives.
| Product | Interest Rate | Access to Money | Best For |
|---|---|---|---|
| Certificate of Deposit | Fixed, usually higher | Locked until maturity; penalty if withdrawn early | Money you will not need for months or years |
| High-Yield Savings Account | Variable, moderate | Withdraw anytime without penalty | Emergency funds and short-term savings |
| Regular Savings Account | Fixed, usually very low | Withdraw anytime without penalty | Everyday banking and small emergency reserves |
| Money Market Account | Variable, moderate | Limited withdrawals per month | Intermediate savings with some flexibility |
A high-yield savings account gives you flexibility if you are not sure how long you can leave money untouched. A regular savings account is best for money you might need at any time. A CD is the right choice when you have a specific time horizon and want the highest may provide rate.
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 certain number of months of interest. For example, a two-year CD might charge six months of interest if you withdraw early. The bank tells you the penalty when you open the CD, so read the terms carefully.
What is the difference between a CD and a savings account?
A savings account lets you withdraw money anytime with no penalty, but pays very low interest. A CD locks your money for a set term and pays higher interest, but charges a penalty if you withdraw early. Choose a savings account for money you might need soon, and a CD for money you can leave alone.
Do I have to pay taxes on CD interest?
Yes. Interest earned on a CD is taxable income in the year you earn it, even if you do not withdraw the money. The bank will send you a 1099-INT form at tax time showing how much interest you earned. You report this on your tax return.
What happens if I do nothing when my CD matures?
Most banks automatically roll your CD into a new one at the current rate. However, some banks charge a fee for this. Check your CD agreement or call the bank before maturity to understand what will happen and whether you want to let it renew or move your money elsewhere.
Are CDs a good investment if inflation is high?
It depends on the CD rate compared to inflation. If a CD pays 4 percent interest but inflation is 5 percent, your money is losing purchasing power. However, if the CD rate is higher than inflation, you are ahead. Compare the CD rate to current inflation before deciding.
