CD rates change daily, and the highest rate today may not be the highest tomorrow
The bank offering the highest CD rate shifts constantly because rates depend on what the Federal Reserve does, what other banks are offering, and how much money each bank needs to attract right now. A bank that leads on 6-month CDs might lag on 5-year CDs. Online banks almost always beat brick-and-mortar banks because they have lower overhead, but some credit unions and regional banks occasionally match or exceed them for specific terms.
Rather than naming a single "highest" bank, you need to know where to look and what to compare. The rate you actually get depends on three things: the term length you choose, the deposit amount, and whether you check today or next week.
Key Takeaways
- Online banks typically offer the highest CD rates because they spend less on physical branches and pass savings to depositors.
- The highest rate for a 3-month CD is often different from the highest rate for a 5-year CD, so compare within your chosen term only.
- CD rates change daily or weekly, so a rate you see today may be gone by the time you fund the account.
- Some banks offer higher rates only on deposits above $25,000 or $100,000, so check the minimum deposit requirement before comparing.
- Rate-tracking websites like Bankrate, DepositAccounts, and the FDIC's own database show current rates across hundreds of banks and let you filter by term and deposit size.
How to find the actual highest rate for your term
Start with a rate-tracking site rather than visiting individual bank websites. Bankrate, DepositAccounts, and MoneySuperMarket all aggregate CD rates from hundreds of banks and update them daily. You can filter by term (3 months, 1 year, 5 years, and so on) and by deposit amount. This takes 10 minutes and shows you the real landscape instead of guessing.
When you find a rate that looks good, check two things before you move money: the bank's deposit insurance status (the FDIC insures up to $250,000 per account type at each bank) and whether the rate is may provide for the full term or subject to change before you fund it. Some banks advertise a rate but reserve the right to lower it before you complete the deposit.
Online banks versus credit unions versus regional banks
Online banks lead on rates most of the time because they have no branch network to maintain. Marcus by Goldman Sachs, Ally Bank, American Express Personal Savings, and Discover Bank have consistently offered top-tier rates, though the specific leader changes week to week. These banks are FDIC-insured and operate the same way as any other bank—you just cannot walk into a physical location.
Credit unions sometimes beat online banks on specific terms, especially if you are a member and the credit union is actively trying to attract deposits. Check your own credit union first if you belong to one. Regional banks occasionally offer competitive rates to draw deposits in their area, but you have to search locally or use an aggregator to find them.
Why the highest rate might not be the right choice for you
A bank offering 5.25% on a 1-year CD is only the right choice if you actually want a 1-year CD. If you need the money in 6 months, that rate does not help you—you will pay an early withdrawal penalty that can wipe out months of interest. Match the CD term to when you actually need the money, then find the highest rate within that term.
Also check the early withdrawal penalty. Some banks charge 6 months of interest; others charge a flat fee or a percentage of the deposit. A slightly lower rate at a bank with a smaller penalty might leave you better off if you end up needing the money early.
Deposit minimums and rate tiers
Many banks offer different rates depending on how much you deposit. A bank might offer 4.75% on a 1-year CD for deposits under $25,000 and 5.10% for deposits of $25,000 or more. When you compare rates, make sure you are looking at the tier that matches your deposit amount. A rate that requires $100,000 to access is not the highest rate available to you if you only have $10,000.
Some banks also offer "bump-up" or "raise-your-rate" CDs that let you increase the rate once during the term if rates rise. These usually start at a slightly lower rate than standard CDs but can pay off if the Fed raises rates while your CD is open. Check whether the bank limits how many times you can bump the rate or whether there are restrictions on when you can do it.
What happens when you find a rate you want
Once you identify a bank and term with a rate you want, open the account and fund it quickly. Rates can change between the time you see them and the time you complete the deposit. Most banks let you open a CD online in 10 to 15 minutes using your Social Security number, address, and a funding source (checking account, savings account, or wire transfer).
After you fund the CD, the rate locks in for the term you chose. You cannot change it, and the bank cannot change it either. Your money sits there earning interest, and on the maturity date the bank either pays you the principal plus interest or automatically rolls it into a new CD at whatever the current rate is (check the bank's policy before funding).
Frequently Asked Questions
Do I have to use the bank with the absolute highest rate?
No. The difference between 5.25% and 5.35% on a $10,000 CD for one year is about $10 in total interest. If the highest-rate bank has poor customer service or a confusing website, a bank offering 5.20% might be worth it. Compare rates, but also read reviews about how the bank handles withdrawals and customer service.
What if rates go up after I open my CD?
Your rate is locked in and will not change, even if the Fed raises rates and other banks start offering 6% or higher. This is the trade-off of a CD: you get certainty, but you also miss out on rate increases. Some banks offer "bump-up" CDs that let you lock in a higher rate once if rates rise, though these usually start at a lower rate.
Can I move my CD to a different bank if I find a better rate?
You can withdraw your money and move it, but you will pay an early withdrawal penalty that typically costs several months of interest. It is usually not worth it unless the new rate is significantly higher and you have a long time left on the current CD. Do the math before you move.
Are online banks safe for CDs?
Yes, as long as they are FDIC-insured. Check the bank's website or the FDIC's bank search tool to confirm. FDIC insurance protects up to $250,000 per account type at each bank, so your CD is as safe at an online bank as it is at a bank with branches.
How often do CD rates change?
Banks can change the rates they offer on new CDs daily or even multiple times per day. Your rate locks in when you fund the CD, so changes do not affect you. But if you are shopping around, check rates on the day you plan to fund the account, not a week earlier.
