What Certificate of Deposit Interest Rates Are
A Certificate of Deposit (CD) is a savings account where you agree to leave money in the bank for a set period — usually three months to five years — in exchange for a fixed interest rate. The bank pays you that rate for the entire term, no matter what happens to market rates. When your term ends, you get your original deposit back plus the interest earned.
The interest rate you receive depends on three things: how long you lock your money away, current market conditions, and which bank you choose. A six-month CD pays less than a five-year CD at the same bank. A bank offering 4.5% pays more than one offering 3.8%. You cannot change the rate once you buy the CD — that is the trade-off for knowing exactly what you will earn.
CDs are different from regular savings accounts because the rate is may provide and usually higher. The catch is that you cannot withdraw the money early without paying a penalty, typically a few months' worth of interest.
Key Takeaways
- CD interest rates are fixed for the entire term and do not change, even if the bank's advertised rate drops.
- Longer terms almost always pay higher rates than shorter ones at the same bank, but your money is locked away longer.
- Interest rates vary between banks, so comparing rates across institutions before you buy can add hundreds of dollars to your earnings.
- Early withdrawal penalties usually cost you several months of interest, so only put money in a CD if you will not need it before the term ends.
- The interest you earn is taxable income and will be reported to the IRS on a Form 1099-INT.
How Banks Set CD Interest Rates
Banks set CD rates based on what the Federal Reserve does with its benchmark interest rate. When the Fed raises rates, banks raise CD rates to compete for deposits. When the Fed cuts rates, CD rates fall. This happens with a lag — banks do not move instantly, and older CDs you already own are not affected.
Banks also compete with each other. A large online bank with low overhead might offer 4.75% on a one-year CD while a local branch bank offers 4.25% for the same term. Shopping around matters. The difference between the highest and lowest rates for the same term can be 0.5% or more, which translates to real money over time.
The length of the term also drives the rate. Banks pay more for longer commitments because they want to lock in your money. A two-year CD typically pays 0.3% to 0.7% more than a six-month CD. A five-year CD pays even more. This is called the yield curve, and it usually slopes upward — longer terms, higher rates.
Comparing Rates Across Different Banks and Terms
CD rates change daily, so the rate you see today may not be the same next week. Before you deposit money, check rates at several banks: your current bank, online banks, credit unions, and regional banks in your area. Sites that aggregate CD rates can show you what is available, though you will need to visit each bank's website to confirm the current rate and open an account.
When comparing, look at the Annual Percentage Yield (APY), not just the interest rate. APY includes the effect of compounding — how often the bank adds interest to your account — so it is the true number to use for comparison. A CD advertising 4.50% APY will earn more than one advertising 4.48% APY, even if the difference seems small.
| Term Length | Typical Rate Range (varies by bank and market) | When Your Money Is Locked Away |
|---|---|---|
| 3 months | 4.0% to 4.5% APY | Very short; good if you need money soon |
| 6 months | 4.2% to 4.7% APY | Half a year; moderate lock-in |
| 1 year | 4.3% to 4.9% APY | One year; common choice |
| 3 years | 4.4% to 5.0% APY | Three years; higher rate for longer wait |
| 5 years | 4.5% to 5.1% APY | Five years; highest rates, longest lock |
These ranges are examples and change constantly. Check current rates directly with banks before deciding.
What Happens to Your Money When the CD Matures
When your CD term ends, the bank sends you a notice — usually 10 days before maturity. At that point, you have choices: withdraw the money, renew the CD for another term at the current rate, or move it to a different product. If you do nothing, many banks automatically renew your CD at whatever rate they are currently offering, which may be lower than what you earned before.
The maturity date is important because it is your window to act without penalty. If you withdraw money after maturity, there is no penalty. If you withdraw before maturity, you lose interest — typically three to six months' worth, depending on the bank and the CD term.
Some banks offer no-penalty CDs that let you withdraw early without losing interest, but they pay lower rates to offset that flexibility. These make sense if you are unsure whether you will need the money, but they cost you in earnings.
Early Withdrawal Penalties and How They Work
If you need your money before the CD matures, the bank will let you take it out, but you will pay a penalty. The penalty is usually stated as a number of months of interest. A CD with a three-month penalty means you lose three months' worth of the interest you earned. On a $10,000 CD earning 4.5% APY, that is roughly $112 in lost interest.
Some banks calculate the penalty differently — as a percentage of the deposit or a flat fee — so read the terms before you buy. The penalty is deducted from your interest earnings first. If you have not earned enough interest to cover the penalty, the bank takes the difference from your principal, meaning you get back less than you deposited.
This is why CDs only make sense for money you genuinely will not need. If there is any chance you will want access to the funds, a regular savings account or money market account is safer, even if the rate is lower.
How Interest Compounds and When You Receive Payments
Interest on a CD compounds, meaning the bank adds interest to your account at regular intervals — usually daily, monthly, or quarterly — and then pays interest on that interest. The more often interest compounds, the more you earn. This is why APY (which accounts for compounding) is higher than the stated interest rate.
Most banks add interest to your CD balance monthly or quarterly and hold it there until maturity. Some CDs let you withdraw interest payments before the term ends without penalty, though this is less common. Check the bank's terms to see when and how often interest is paid.
On a $10,000 CD earning 4.5% APY compounded daily for one year, you would earn approximately $461 in interest. The exact amount depends on how the bank calculates daily compounding, so ask for a projection before you commit.
Tax Implications of CD Interest
The interest you earn on a CD is taxable income. The bank will send you a Form 1099-INT in January showing how much interest you earned in the previous year. You report this on your tax return, and you owe federal income tax on it at your regular tax rate. Some states also tax CD interest.
This matters because it reduces your actual return. If you earn $461 in interest and you are in the 22% federal tax bracket, you owe roughly $101 in taxes, leaving you with $360 in after-tax earnings. The higher your tax bracket, the bigger the bite.
If you hold a CD in a tax-advantaged account like a traditional IRA or Roth IRA, the interest is not taxed until you withdraw from the account (or not at all, in the case of a Roth). This is one reason some people use CDs inside retirement accounts.
Frequently Asked Questions
Can I get my money out of a CD before it matures?
Yes, but you will pay an early withdrawal penalty, usually three to six months of interest. Some banks offer no-penalty CDs that let you withdraw without penalty, but they pay lower rates. Check your CD's terms before you buy to understand the exact penalty.
What is the difference between APY and the interest rate?
The interest rate is the percentage the bank pays. APY (Annual Percentage Yield) is the rate after accounting for compounding — how often the bank adds interest to your balance. APY is always equal to or higher than the stated rate and is the number to use when comparing CDs.
Should I buy a long-term CD or a short-term CD?
Long-term CDs pay more, but your money is locked away longer. If you think interest rates will fall, a longer term locks in higher rates. If you think rates will rise, a shorter term lets you reinvest at higher rates sooner. If you are unsure, a one-year CD is a common middle ground.
What happens if the bank fails while I have a CD?
The Federal Deposit Insurance Corporation (FDIC) insures CDs up to $250,000 per depositor per bank. If the bank fails, you get your principal and accrued interest back, up to that limit. Credit union CDs are insured similarly by the National Credit Union Administration (NCUA).
Can I move money from a CD to another bank without penalty?
Only after the CD matures. Once the term ends, you can withdraw the money penalty-free and deposit it anywhere. Before maturity, you pay the early withdrawal penalty. Some banks will waive the penalty if you are moving to another CD with them, so it is worth asking.
