A good CD rate depends on what other banks are offering right now, not on a fixed number
There is no single "good" CD rate that applies everywhere. What matters is how a bank's rate compares to what other banks are paying on the same type of CD at the same time. A 4.5% rate might be excellent one month and below average the next, depending on what the Federal Reserve does and how banks respond.
The practical way to find a good rate is to check what at least three to five banks are currently offering for the CD term you want—whether that is three months, one year, five years, or something else. Then pick the bank offering the highest rate, assuming the bank is FDIC-insured and the CD terms match what you need.
Rates change frequently, sometimes weekly. Online banks and credit unions tend to offer higher rates than brick-and-mortar banks because they have lower overhead costs. If you see a rate that looks unusually high compared to competitors, it is worth double-checking that you understand the full terms—some banks offer promotional rates that drop after a certain period.
Key Takeaways
- A good CD rate is one that is higher than what most other banks are offering for the same term on the same day you are shopping.
- Online banks and credit unions typically offer higher rates than traditional banks because they have fewer physical locations to maintain.
- Rates change frequently enough that comparing at least three banks before opening a CD is worth the time.
- A promotional rate that looks unusually high may drop after a set period, so read the full disclosure before committing your money.
- The Federal Reserve's interest rate decisions affect CD rates across the industry, so rates you see today may not be available next month.
How to compare CD rates across banks
Start by listing the banks you already use or trust, then add two or three online banks or credit unions you have not used before. Visit each bank's website and look for the CD rates page—it is usually under "Savings" or "Products." Write down the rate for the exact term you want (three months, one year, five years, and so on) and the minimum deposit required.
Pay attention to whether the rate is fixed for the entire term or promotional. A fixed rate stays the same from the day you open the CD until it matures. A promotional rate is higher for a limited time, then drops to a standard rate. The disclosure should tell you both numbers, but you may have to read carefully or call the bank to confirm.
Once you have rates from at least three banks, the highest rate is usually the best choice—but only if the bank is FDIC-insured (for banks) or NCUA-insured (for credit unions). This insurance protects your money up to $250,000 if the bank fails. Every legitimate bank and credit union displays this information on their website.
Why rates vary between banks and over time
Banks set CD rates based on what the Federal Reserve charges them to borrow money. When the Fed raises its interest rate, banks can afford to pay more on CDs because they are earning more themselves. When the Fed lowers rates, banks lower CD rates too. This is why a rate that was good three months ago may no longer be competitive.
Banks also compete for deposits. If one bank raises its CD rates to attract more customers, others often follow within days or weeks. Online banks can offer higher rates because they do not pay for branch locations, staff, or ATM networks. Credit unions, which are member-owned rather than profit-driven, sometimes offer competitive rates as a benefit to members.
Some banks offer promotional rates to new customers or for large deposits. These rates are real—you will actually earn that percentage—but they may be temporary. A bank might offer 5.0% for the first three months, then drop to 3.5% for the remainder of a one-year CD. Always ask whether the rate you are seeing is promotional or standard.
The difference between shopping early and waiting for rates to rise
If you have money sitting in a savings account earning almost nothing, moving it to a CD at today's rate is usually better than waiting. You lock in a may provide return, and you cannot lose money if rates rise later. The trade-off is that if rates fall, you are glad you locked in the higher rate.
If rates are falling, locking in a CD now protects you. If rates are rising, you might earn more by waiting—but you also risk that rates will rise more slowly than you expect, or that you will need the money before the CD matures and face an early withdrawal penalty. Most people are better off opening a CD when they have money to save, rather than trying to time the market.
One middle-ground strategy is a CD ladder: open multiple CDs with different maturity dates (one maturing in one year, one in two years, one in three years, and so on). As each one matures, you can open a new CD at whatever rate is available then. This spreads your risk and gives you regular chances to move money into higher-rate CDs if rates rise.
What to check before opening a CD
Beyond the interest rate, confirm the minimum deposit amount. Some banks require $500, others $1,000 or $10,000. If you do not have the minimum, that bank is not an option for you, no matter how good the rate is.
Check the early withdrawal penalty. If you need the money before the CD matures, the bank will charge you a penalty—usually a certain number of months of interest. A CD with a 3-month penalty is less risky than one with a 12-month penalty if you think you might need the money. The bank must disclose this penalty before you open the account.
Confirm whether the bank compounds interest daily, monthly, or at maturity. Daily compounding means you earn interest on your interest more often, which adds up to slightly more money by the time the CD matures. This difference is small but real over longer terms.
Where to find current CD rates
You can check rates directly on bank websites, but comparison sites like Bankrate, DepositAccounts, and the FDIC's own rate search tool let you see many banks at once. These sites update frequently but not in real time, so always confirm the rate on the bank's website before opening an account.
Your own bank or credit union may not have the highest rate, but they may offer other benefits—no fees, easier access to customer service, or integration with your checking account. If the rate difference is small (less than 0.5%), staying with your current bank might be worth it for convenience.
If you are shopping for a CD, you are likely to see ads for promotional rates. These are real, but they are designed to attract new customers. Existing customers at the same bank may not may have access to for the promotional rate, so ask before assuming you can open a CD at the advertised rate.
How CD rates fit into your overall savings plan
A CD is not the only place to keep money you are saving. High-yield savings accounts earn interest that changes with the market, so you are not locked into a rate. Money market accounts offer similar flexibility. CDs are best for money you know you will not need for a specific period—a down payment you are saving for in two years, or an emergency fund you want to protect from yourself.
If you have a large amount to save, splitting it between a CD and a high-yield savings account gives you both may provide returns and flexibility. The CD earns a slightly higher rate, and the savings account lets you access money without penalty if something unexpected happens.
Frequently Asked Questions
Is a 4% CD rate good right now?
That depends on what other banks are offering on the same day. Check at least three banks offering the same CD term. If 4% is higher than most competitors, it is good. If most banks are offering 4.5% or higher, it is below average. Rates change weekly, so what is good today may not be good next month.
Should I open a CD if I think interest rates will go up?
If rates rise after you open a CD, you will be earning less than you could have earned. But you also cannot predict when or how much rates will rise. Most people are better off opening a CD when they have money to save, rather than waiting for a perfect moment. A CD ladder—opening multiple CDs with different maturity dates—spreads the risk.
What is the difference between a CD and a savings account?
A CD locks your money away for a set term in exchange for a higher interest rate. A savings account lets you withdraw money anytime, but usually earns a lower rate. If you need the money before the CD matures, you pay an early withdrawal penalty. Savings accounts have no penalty.
Can I move my CD to a different bank if I find a better rate?
You can, but you will pay an early withdrawal penalty if you close the CD before it matures. The penalty usually costs more than the difference in rates between banks, so it is not worth switching mid-term. When your CD matures, you can move the money to a bank with a better rate at that time.
Do I have to pay taxes on CD interest?
Yes. The interest you earn on a CD is taxable income. The bank will send you a 1099-INT form at the end of the year showing how much interest you earned. You report this on your tax return. This is true whether the CD is at a bank or credit union.
