Best jumbo CD rates for September 2026: Up to 4.35% APY

If you're looking for a safe place to park significant savings, a jumbo CD could be the right choice. Most jumbo CDs require a minimum deposit of at least $100,000, but offer high rates in return.

As rates change, keep an eye out for how jumbo CD rates compare to standard certificates. These days, you can often find similar rates with a much lower minimum (or none at all).

CNBC Select compared dozens of accounts to determine which jumbo CDs have the best rates, at a variety of terms. See our methodology for more information on how we made our selections. (Rates current as of Sept. 2, 2026)

A certificate of deposit (CD) is a deposit account that earns a fixed interest rate for a set term, usually between three months and five years. With a standard CD, you can't touch the funds once you open the account without paying an early withdrawal penalty.

Jumbo CDs require a larger initial investment, usually at least $50,000 or $100,000.

1. You can only deposit money into the CD once at the beginning of the term. You can't make additional contributions over the CD's term. Jumbo CDs usually have a minimum deposit requirement of at least $50,000 to $100,000.
   
2. You can't access your money before your term ends or you'll get hit with an early withdrawal penalty. The penalty fees can vary depending on your bank and your CD's term length, but it's usually the interest earned or the interest you would have earned, over a certain number of days or months. Generally, the longer the CD term length, the costlier the withdrawal penalty.
   
3. Once the CD matures (when the term is over), savers can get their money back, in addition to the interest earned over time, or move the money into a new CD. CD terms usually auto-renew at the rate offered at maturity if you don't do anything.
   
4. Unlike high-yield savings accounts, CDs have fixed rates. That can be an advantage if you lock in a competitive rate before the Federal Reserve cuts its benchmark rate. On the other hand, if you open a CD before interest rates rise, you could miss out on higher yields on new CDs.

To pick the right CD, start by looking for banks that offer jumbo CDs. From there, consider these other factors:

• APYs and terms: Shop banks, credit unions and online institutions to find one with the best rate at the term you want.
• Minimum deposit: Jumbo CDs can require as much as $100,000 or more.  
• Early withdrawal penalty: See what the fee is if you take your money out early. It might be worth a slightly lower APY if you have more flexibility.
• Compounding interest: See whether interest compounds daily or monthly.
• Customer service: Does the bank have physical branches for in-person banking or robust digital banking features
• FDIC or NCUA insurance: Only open an account at a bank or credit union with deposits that are federally insured up to $250,000 per depositor, per ownership category.

As with any financial product, jumbo CDs have benefits and drawbacks.

At CNBC Select, our mission is to provide our readers with high-quality service journalism and comprehensive consumer advice so they can make informed decisions with their money. Every CD list is based on rigorous reporting by our team of expert writers and editors with extensive knowledge of savings and banking products. While CNBC Select earns a commission from affiliate partners on many offers and links, we create all our content without input from our commercial team or any outside third parties, and we pride ourselves on our journalistic standards and ethics. See our methodology for more information on how we choose the best jumbo CDs.

To determine the best jumbo CDs, CNBC Select compared dozens of options offered by online banks and credit unions. We found that many of the best jumbo CD rates are offered by credit unions, but we only considered those credit unions that had membership eligibility open to anyone.

When ranking the top jumbo CDs, we prioritized the ones offering the highest APYs. We then compared jumbo CDs by looking at their minimum deposit requirements, penalties for early withdrawals, ease of use and industry rankings. We also considered CNBC Select audience data when available, such as general demographics and engagement with our content and tools. We ranked our top picks by best for three-month jumbo CD, best for six-month jumbo CD, best for one-year jumbo CD, best for 18-month jumbo CD and best for five-year jumbo CD.

All of the CDs included on this list are FDIC- or NCUA-insured up to $250,000 per person. The rates and fee structures banks advertise for their CD accounts are not guaranteed forever. They are subject to change without notice and they often fluctuate in accordance with the Fed rate. If you open a CD account, however, you're often locked into that APY offered at account opening for the entire term length.

Your earnings depend on the CD term length, the amount you deposit, the APY offered when you opened the account and any associated fees. Generally, a larger deposit and a higher interest rate will earn you the most money. Any early withdrawals may result in penalty fees that lower your principal balance/earnings.

To open a CD account for the first time at a bank, most banks and institutions require a deposit of new money, meaning you can't transfer money you already had in an account at that bank.
