What Is a Certificate of Deposit and How Does It Differ From a Savings Account
A Certificate of Deposit, commonly called a CD, is a financial product offered by banks and credit unions. When you put money into a CD, you agree to keep that money there for a set period of time. In return, the financial institution pays you interest on your deposit. The key difference between a CD and a regular savings account is the time commitment and the interest rate.

With a savings account, you can withdraw your money whenever you want without penalty. However, savings accounts typically offer lower interest rates—often between 0.01% and 5% annually, depending on market conditions and the bank. A CD requires you to leave your money untouched for a fixed period, which might be 3 months, 6 months, 1 year, 3 years, or 5 years. Because the bank knows your money will stay there, they offer higher interest rates. As of 2024, CD rates range from about 4% to 5.35% depending on the term length and current economic conditions.
When your CD reaches its maturity date (the end of the agreed-upon time period), you have options. You can withdraw your money plus the interest earned. You can also choose to "roll over" the CD, which means the bank automatically puts your money into a new CD. Some banks allow you to add money during a rollover period, though most CDs don't allow deposits after the initial purchase.
If you need to withdraw money before the maturity date, most banks charge an early withdrawal penalty. This penalty typically ranges from one month to one year of interest, depending on the CD's term. For example, if you have a 5-year CD with a penalty of six months' interest, and you withdraw after two years, you'll lose six months of the interest you earned.
Practical Takeaway: CDs work best for money you won't need for a specific period. If you have funds set aside for a goal that's several months or years away, a CD can grow that money faster than a regular savings account. Before opening a CD, make sure you have other accessible savings for emergencies, since early withdrawal penalties can reduce your earnings.
Understanding CD Terms, Maturity Dates, and What Happens When They End
The term of a CD is the length of time you commit to keeping your money invested. This is one of the most important features to understand because it directly affects both your interest rate and when you can access your money without a penalty. Common CD terms include 3-month, 6-month, 1-year, 2-year, 3-year, and 5-year options. Some banks also offer unusual terms like 18 months or 4 years.

Generally, longer-term CDs pay higher interest rates than shorter-term CDs. This is because the bank has your money for a longer period and can use it for their own purposes. For instance, if a bank is offering 2.5% for a 6-month CD, they might offer 4.5% for a 5-year CD. This difference is called the "yield curve," and it encourages people to lock up their money for longer periods. However, this relationship isn't always true—sometimes the rates are similar or inverted—depending on what's happening in the overall economy.
The maturity date is the exact day your CD term ends. On that date, your money becomes available. Here's what typically happens: First, your CD stops earning interest. Next, you receive your principal (the original amount you deposited) plus all the interest that accumulated during the term. Then you have a window of time—usually 7 to 14 days, though it varies by bank—to decide what to do with your money. During this window, you can withdraw everything without a penalty, or you can let the bank roll it over into a new CD.
If you do nothing during the rollover window, many banks automatically roll your CD into a new one with the same term length at the current interest rate. This is convenient if you want to keep your money invested, but the new rate might be higher or lower than what you were earning. Some people miss this window because they forget about their CD, and they end up locked in at rates they didn't intend. To avoid this, many banks send reminder notices before the maturity date, and some allow you to set up alerts through online banking.
Practical Takeaway: Mark your CD maturity date on your calendar or set a phone reminder. Review your bank's current CD rates before your CD matures so you can make an informed decision about rolling over. If rates have dropped significantly, you might want to withdraw your money instead, or you could divide it among multiple CDs with different maturity dates—a strategy called "laddering" that gives you access to portions of your money at different times.
How Interest Rates Work on CDs and What Influences Them
CD interest rates determine how much extra money you'll earn on your deposit. The rate is expressed as an annual percentage yield, or APY. This number tells you what percentage of your principal you'll earn over one year. For example, if you put $10,000 into a CD with a 5% APY, you'll earn approximately $500 in one year, though the actual amount depends on how frequently the bank compounds the interest.

Interest compounding means the bank calculates interest on both your original deposit and any interest you've already earned. Most CDs compound interest daily, though some compound monthly or quarterly. Daily compounding gives you slightly more earnings because you're earning interest on interest more frequently. Using a simple example: on a $10,000 CD earning 5% APY compounded daily, you'd earn about $512.68 over one year, whereas if it compounded annually, you'd earn exactly $500.
Several factors influence what CD rates banks offer. The most significant is the Federal Reserve's benchmark interest rate, called the federal funds rate. When the Federal Reserve raises this rate, banks typically raise CD rates to attract deposits. When the Fed lowers the rate, CD rates usually fall. The Federal Reserve doesn't set CD rates directly—banks set their own rates—but they follow the Fed's direction. Between 2020 and 2023, the Fed raised rates from near zero to over 5%, which caused CD rates to rise dramatically from around 0.5% to over 5%.
Other influences on CD rates include the bank's operating costs, competition from other banks, the bank's funding needs, and economic outlook. During recessions, rates tend to be lower because banks expect lower demand for loans. During periods of strong economic growth, rates tend to be higher. Banks with lower operating costs can offer higher CD rates. Online banks, which have minimal physical branches, often offer higher rates than traditional brick-and-mortar banks because their costs are lower.
The specific term of a CD also affects its rate. As mentioned earlier, longer terms typically have higher rates. However, there are exceptions. If the economy is expected to weaken, the Fed might lower rates, and banks might offer lower rates for longer-term CDs to avoid locking in high rates for extended periods. This situation—where shorter-term CDs pay more than longer-term CDs—is called an inverted yield curve, and it's relatively unusual.
Practical Takeaway: Compare CD rates across multiple banks before opening a CD. Online banks often offer 0.5% to 1% higher rates than traditional banks. A 1% difference on a $10,000 CD earning over one year equals $100 in additional earnings. Also track the Federal Reserve's interest rate decisions—you can find this information on the Federal Reserve's official website. If the Fed is expected to cut rates soon, locking in a CD now might be wise. If rates are expected to rise, you might consider a shorter-term CD so you can reinvest at higher rates sooner.
Calculating Your CD Earnings and Understanding the Difference Between APY and APR
Calculating how much money you'll earn from a CD involves understanding annual percentage yield, or APY. APY is different from annual percentage rate, or APR. Both are expressed as percentages, but they measure different things. APR shows the simple annual interest rate without accounting for compounding. APY includes the effect of compounding, so it represents the total amount you'll actually earn over one year. Because of this difference, APY is always equal to or higher than APR. For financial products like CDs where you earn interest, APY is the more useful number because it shows your real earnings.
