The banks offering the best CD rates change weekly, so the "best" one depends on the term you want and when you're checking

No single bank always has the highest rates. CD rates move constantly — sometimes daily — and different banks lead in different categories. A bank might offer 5.25% on a one-year CD but only 4.80% on a five-year CD, while another bank does the opposite. The bank with the best rate today may not have it next week.

The highest rates right now are almost always at online banks and credit unions, not at the brick-and-mortar branches you see on Main Street. Online banks have lower overhead costs, so they pass higher rates to depositors. Credit unions, which are member-owned rather than shareholder-owned, often do the same. Traditional banks like Chase, Bank of America, and Wells Fargo typically offer rates well below what you can find elsewhere.

To find the current best rate for your specific term, you need to check multiple sources on the same day — rates shift too fast for any article to stay current. The sites that track CD rates in real time include Bankrate, DepositAccounts, and the FDIC's own rate search tool. Each shows rates from dozens of banks and credit unions, sorted by term length and APY (annual percentage yield).

Key Takeaways

  • Online banks and credit unions consistently offer higher CD rates than traditional banks because their operating costs are lower.
  • The highest rate for a one-year CD may come from a different bank than the highest rate for a five-year CD, so compare within your specific term.
  • CD rates change daily, so checking a rate comparison site on the day you plan to open the CD gives you the most accurate picture.
  • You can open a CD at a bank where you don't have a checking account, so you're not limited to your current bank's rates.
  • The FDIC insures CDs up to $250,000 per depositor per bank, so a higher rate at a smaller bank carries the same deposit protection as a larger one.

How to compare rates across banks and credit unions

Start by deciding what term you want — three months, six months, one year, three years, five years, or longer. Then go to Bankrate.com, DepositAccounts.com, or the FDIC's National Rate Search and filter by that term. The sites will show you the current APY from each institution, ranked from highest to lowest.

Look at the minimum deposit required. Some banks require $500 to open a CD; others require $25,000. If you don't have the minimum, that bank's rate doesn't matter to you. The minimum is usually listed right next to the rate.

Check whether the bank is FDIC-insured (for banks) or NCUA-insured (for credit unions). This matters because your deposit is protected up to $250,000 if the institution fails. Nearly all banks and credit unions are insured, but it's worth confirming. The comparison sites usually show this with a small icon or note.

Once you've narrowed it down to two or three banks with rates you like and minimums you can meet, visit each bank's website directly to confirm the rate hasn't changed since the comparison site updated. Rates can shift between the time a comparison site refreshes and the time you open the account.

Why online banks lead on CD rates

Online banks don't maintain physical branches, so they spend far less on real estate, staff, and equipment. That cost savings gets passed to depositors as higher rates. A bank like Marcus by Goldman Sachs or Ally Bank can offer rates 0.50% to 1.00% higher than Chase or Bank of America because they have no branches to maintain.

Credit unions operate on a similar principle — they're owned by their members rather than shareholders, so profits go back to members through better rates and lower fees. You typically need to meet a membership requirement (living in a certain county, working for a certain employer, or belonging to a certain organization), but many credit unions have opened their membership to anyone who makes a small donation to a may have access to charity.

The tradeoff is convenience. You can't walk into an online bank's office to ask questions or deposit cash. Everything happens by mail, phone, or online portal. For a CD, which you're not touching for months or years anyway, that tradeoff usually makes sense.

What to watch for when opening a CD online

Confirm the rate is locked in for the full term. Once you open the CD, the rate should not change, even if the bank's advertised rates drop. This is standard, but it's worth verifying in the terms before you fund the account.

Understand 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 one-year CD might have a penalty of three months of interest; a five-year CD might have a penalty of six months. The penalty is listed in the CD's terms. If you think you might need the money, look for a CD with a lower penalty or choose a shorter term.

Check how the bank transfers funds. Most online banks let you link your existing checking account and transfer money electronically. Some require a wire transfer, which may cost $15 to $25. A few still accept checks by mail. The method affects how quickly your CD opens and whether you'll pay a fee.

Verify the maturity date and what happens when it arrives. When your CD matures, the bank will either deposit the money back into your linked account or automatically renew it into a new CD at the current rate. Read the terms to see which happens by default, and decide in advance what you want to do.

Comparing a high-rate online CD to your current bank's CD

Let's say your bank offers 4.50% on a one-year CD and you have $10,000 to deposit. After one year, you'd earn $450 in interest. If an online bank offers 5.25% on the same term, you'd earn $525 — a difference of $75. That might not sound like much, but it's money you're leaving on the table by staying with your current bank.

Over a five-year CD, the difference compounds. At 4.50%, $10,000 grows to $12,460. At 5.25%, it grows to $12,850 — nearly $400 more. The higher the rate and the longer the term, the bigger the gap.

The only reason to use your current bank's CD is if you value the convenience of managing everything in one place, or if your bank offers perks (like waiving the early withdrawal penalty for account holders) that offset the lower rate. For most people, the extra interest from a higher-rate CD outweighs the minor inconvenience of opening an account elsewhere.

How to act when you find a rate you want

Once you've found a bank with a rate that works for you, open the account the same day if possible. Rates can change overnight, and you want to lock in the rate you saw. Most online banks let you open a CD in 10 to 15 minutes by providing your name, address, Social Security number, and linking a bank account.

After you submit the application, the bank will verify your identity and may place a small hold on your linked account (usually $0.01 to $1.00) to confirm you control it. Once that clears, you can transfer the full amount you want to deposit into the CD. The CD officially opens once the funds arrive and clear, which typically takes one to three business days.

Save the CD's terms and maturity date somewhere you'll remember them. Set a calendar reminder for a month before the CD matures so you can decide whether to renew, move the money elsewhere, or withdraw it.

Frequently Asked Questions

Can I move a CD from one bank to another without losing the rate?

No. Once a CD matures, you can open a new CD at a different bank at whatever the current rate is — which may be higher or lower. You cannot transfer an existing CD to another bank mid-term without triggering the early withdrawal penalty. Wait until maturity, then shop for the best rate at that time.

What's the difference between APY and APR on a CD?

APY (annual percentage yield) includes the effect of compounding — interest earned on interest. APR (annual percentage rate) does not. Banks advertise CD rates as APY, which is the number you should compare. APY is always slightly higher than APR for the same CD.

Is my money safe in an online bank's CD?

Yes, as long as the bank is FDIC-insured. The FDIC insures deposits up to $250,000 per depositor per bank, regardless of whether the bank has physical branches. An online bank's CD is just as protected as a traditional bank's CD.

Do I have to keep the CD open for the full term?

No, but if you withdraw the money early, you'll pay a penalty. The penalty is usually a set number of months of interest — for example, three months of interest on a one-year CD. The terms tell you exactly what the penalty is before you open the account.

Can I open multiple CDs at the same bank?

Yes. You can open a one-year CD, a three-year CD, and a five-year CD all at the same bank if you want to ladder your money across different terms. Each CD is insured separately up to $250,000, so you're protected on all of them.
