The banks offering the highest CD rates change weekly, and online banks almost always beat brick-and-mortar branches
The highest CD rates are almost never at the bank where you keep your checking account. Online banks and credit unions typically offer rates 0.5% to 1.5% higher than traditional banks because they have lower overhead costs and compete aggressively for deposits. As of now, rates vary by term length and institution, but online banks like Marcus, Ally, and American Express Personal Savings regularly appear at the top of rate comparison lists. The exact highest rate shifts constantly—sometimes daily—so the bank in first place this week may drop below others next week.
The second thing to know is that you should never assume a bank's advertised rate applies to all CD terms. A bank might offer 5.25% on a 1-year CD but only 4.80% on a 3-year CD. You need to check the specific term you want before you commit money. Rate comparison sites like Bankrate, DepositAccounts, and DepositRates let you filter by term length and see which banks are paying the most for the exact CD you're considering.
Key Takeaways
- Online banks and credit unions consistently offer higher CD rates than traditional banks, often 0.5% to 1.5% percentage points above what you'll find at a branch.
- CD rates vary by term length, so a bank's best 1-year rate may not be its best 3-year or 5-year rate—always check the specific term you want.
- Rate comparison sites show current rates from dozens of banks and let you sort by term, so you can see which institution pays the most for your time horizon.
- FDIC insurance covers up to $250,000 per depositor per bank, so splitting money across multiple banks protects larger sums if you're chasing the highest rates at different institutions.
Online banks versus traditional banks: why the gap exists
Online banks have no physical branches, no tellers, and no regional marketing budgets. That means they pass savings directly to depositors through higher CD rates. Marcus (owned by Goldman Sachs), Ally Bank, and American Express Personal Savings are three of the most reliable online banks for competitive CD rates, but dozens of smaller online banks compete in the same space. The trade-off is that you cannot walk into a branch or speak to someone in person—everything happens by phone, email, or online portal.
Traditional banks (Chase, Bank of America, Wells Fargo, Citibank) typically offer lower CD rates because they maintain physical locations and pay for in-person service. If you value the ability to sit down with someone or deposit cash at a branch, that convenience costs you in lower returns. Some people accept the lower rate as the price of that service; others move their CD money to an online bank and accept the digital-only experience to earn more.
Credit unions often split the difference. They are member-owned, not shareholder-owned, so they can offer rates closer to online banks while sometimes maintaining a physical location. However, credit unions have membership requirements—you may need to live in a certain area, work for a specific employer, or belong to a particular organization. If you may have access to for a credit union, it is worth checking their CD rates against online banks.
How to compare rates across multiple banks at once
Rate comparison sites do the heavy lifting for you. Bankrate, DepositAccounts, and DepositRates all pull current rates from dozens of banks and update them multiple times per day. You enter the CD term you want (1 year, 3 years, 5 years, etc.) and your deposit amount, and the site shows you which banks are paying the most, ranked from highest to lowest.
These sites are free to use and do not require you to enter personal information to see rates. They make money from banks that pay for placement or from referral fees when you open an account through their link—but the rates themselves are real and current. The downside is that not every small bank or credit union appears on every comparison site, so if you have a specific institution in mind, it is worth checking their website directly as well.
When you find a rate you like, note the bank's name, the CD term, the rate, and the date you checked it. Rates change constantly, so what was true on Monday may not be true on Thursday. If you wait more than a few days to open the CD, check the rate again before you fund it.
Understanding the difference between APY and APR on CDs
APY (annual percentage yield) is the number that matters for CDs. It includes both the interest rate and the effect of compounding—how often the bank adds earned interest back into your account so you earn interest on that interest. A CD with 5.00% APY will earn you more money than one with 5.00% APR because APY accounts for compounding.
Banks are required to show you the APY when they advertise a CD rate, so you will almost always see APY listed first and prominently. If you see only APR, that is a red flag—ask the bank for the APY before you commit. For most CDs, the difference is small (often less than 0.01%), but on large deposits or longer terms, it adds up.
What to watch for when comparing rates at different banks
Not all CDs are identical even when the rate is the same. Some banks compound interest daily, others monthly. Some allow you to add money to the CD after you open it (called a "bump-up" or "add-on" CD), while others lock you in with a fixed amount. Some charge a penalty for early withdrawal that is steep enough to erase months of interest; others have smaller penalties. These details matter, especially if you think you might need the money before the CD matures.
Read the fine print on the bank's CD page before you open an account. Look for the early withdrawal penalty (usually expressed as a number of months of interest), the compounding frequency, and whether the CD allows additional deposits. A CD with a slightly lower rate but a smaller early withdrawal penalty might be the smarter choice if you are uncertain about keeping the money locked up for the full term.
Also check whether the bank is FDIC-insured. All legitimate banks are, but it is worth confirming on the FDIC's official bank search tool (BankFind) if you are opening a CD at a bank you have never heard of. FDIC insurance protects up to $250,000 per depositor per bank, so if you are depositing more than that, you will need to split the money across multiple banks to keep it all insured.
Why rates change and how often to check
CD rates move in response to the Federal Reserve's interest rate decisions. When the Fed raises its benchmark rate, banks have more incentive to offer higher CD rates to attract deposits. When the Fed cuts rates, CD rates fall. The Fed meets eight times per year, and markets often anticipate rate changes weeks in advance, so CD rates can shift even on weeks when the Fed does not meet.
If you are shopping for a CD, check rates at least once per week if you are in no rush, or daily if you are ready to fund the CD within a few days. Rates can move 0.25% or more in a single week, which translates to real money on a large deposit. However, do not wait forever chasing the absolute highest rate—if you see a rate that meets your goal, open the CD. Trying to time the market for CDs usually backfires.
Laddering CDs to balance rate and access
If you have a large sum to invest and want to balance earning a high rate with having access to some of your money before everything matures, consider a CD ladder. This means opening multiple CDs with different maturity dates—for example, one 1-year CD, one 2-year CD, one 3-year CD, and one 4-year CD, each with the same amount of money. Every year, one CD matures and you can withdraw the money, reinvest it in a new 4-year CD, or use it for something else.
Laddering lets you capture higher rates on longer-term CDs (which usually pay more than short-term ones) while still having access to a portion of your money each year. It also protects you if rates rise after you open your CDs—when the 1-year CD matures, you can reinvest at the new, higher rate. The downside is that you have to manage multiple CDs and remember when each one matures.
Frequently Asked Questions
Do I have to open a CD at the bank where I have my checking account?
No. You can open a CD at any bank, including one where you have no other accounts. Many people open CDs at online banks that offer the highest rates while keeping their checking account at a traditional bank for convenience. You will need to provide your bank account information to fund the CD, but the CD itself can be at a completely different institution.
What happens if I need the money before the CD matures?
You can withdraw it, but you will pay an early withdrawal penalty. The penalty is usually a certain number of months of interest—for example, 150 days of interest on a 1-year CD. On a high-rate CD, this penalty might erase three to six months of earnings. Read the penalty terms before you open the CD so you know what it will cost if you need the money early.
Is it safe to open a CD at an online bank I have never heard of?
If the bank is FDIC-insured, your money is protected up to $250,000, the same as at any other bank. You can check whether a bank is FDIC-insured by searching the FDIC's BankFind tool on their website. The main risk is not safety but poor customer service if something goes wrong—so stick with banks that have reviews and a track record, or choose a well-known online bank like Marcus or Ally.
Should I open multiple CDs at different banks to get higher rates?
Yes, if you have more than $250,000 to invest. Since FDIC insurance covers up to $250,000 per bank, splitting money across multiple banks protects all of it. You can also open CDs at different banks simply to capture the highest rate for each term length—one bank might pay the most for 1-year CDs while another pays the most for 5-year CDs.
How long does it take to open a CD online?
Usually 10 to 15 minutes. You will need your Social Security number, address, and bank account information (to fund the CD). The bank will verify your identity and may place a small temporary hold on your checking account to confirm it is real. The CD typically opens within one business day, though some banks open them instantly.
