You can often find highly competitive yields on share certificates, also called certificates of deposit (CDs), at credit unions — as good as what you can find at online banks, which tend to pay the highest rates. But you need to read up on a credit union’s membership policies to see if you’re eligible to join and open a CD. Here, you’ll find the top CD rates at credit unions that Bankrate reviews, including some whose membership is open to anyone.

Bankrate’s picks for top credit union CD rates

Bankrate only includes credit unions that are insured by the National Credit Union Share Insurance Fund (NCUSIF).

Mountain America Credit Union

Rating: 4.4 stars out of 5
4.4 Bankrate CD score
  • Annual percentage yield

    3.75% – 4.20%
  • Min. deposit to open

    $500
  • Term

    6 months - 5 years

Why Mountain America Credit Union?

Mountain America Credit Union offers competitive yields on all of its CDs, which range from six months to five years — its two-year CD rate stands out at a stellar 4.20%. The minimum deposit to open a certificate is $500, which is pretty standard. Or you can open an add-on Growth CD with only $5. They earn the same APY as the standard CDs but require you to add money monthly (at least $10 every month). It’s rare that you can add money to a CD, so this is a great option if you want a CD's guaranteed rate but don’t have a lot saved. Membership to this credit union is restricted. One way to join is to be a resident of certain Utah counties. For the full list membership eligibility, visit the credit union’s website.

America First FCU

  • Annual percentage yield

    3.90% – 4.10%
  • Min. deposit to open

    $500
  • Term

    3 months - 5 years

Why America First FCU?

America First Credit Union's share certificate terms range from three months to five years — and yields on all of them beat inflation, a rare achievement these days. There’s an industry-typical minimum deposit of $500. You can also open individual retirement account (IRA) CDs and bump-rate CDs. The last have slightly lower rates than their standard CDs, but you can adjust the rate once if offered rates rise. Membership to this credit union is mostly restricted to those who live in Arizona, Idaho, Nevada, New Mexico, Oregon, Utah and Washington. There are a few other ways to join that you can check on the credit union’s website.

    2.95% – 3.90%
  • Min. deposit to open

    $500

Why SchoolsFirst Federal Credit Union?

SchoolsFirst Federal Credit Union offers tiered rates for its CDs: The more money you put in, the higher the APY. With a minimum deposit of $500, you’ll earn 3.90% APY on a 5-year CD but with $50,000, you’ll earn 4.00%. The credit union provides a wide variety of CD terms, from as short as 30 days to as long as five years. Most of the rates, even at the lowest deposit tier, are strong. The field of membership is restricted mostly to employees or those affiliated in certain ways with California schools.

  • Term

    3 months - 5 years

Why Quorum Federal Credit Union?

You can open a certificate at Quorum Federal Credit Union with as little as $100, which is a lower requirement than many of the CDs on this list. The best rates here belong to its longer CD terms, though you earn 0.10% more on deposits of $100,000 or more. The early withdrawal penalty here works differently than at most institutions. Instead of days’ worth of interest, you’ll be charged a percentage of the amount withdrawn. Anyone can join Quorum by becoming a member of the American Consumer Council (ACC), which you can do during the application process for Quorum.

    $500
  • Term

    6 months - 5 years

Why First Tech Federal Credit Union?

First Tech Federal Credit Union’s CDs come in three varieties: promotional certificates (which require new-to-the-credit-union money); bump-up certificates (which let you add more money to the certificate every year) and standard certificates. All of these come with a 10-day rate guarantee (if the rate goes up 10 days after you open one, you’re eligible for the higher rate). Anyone can join the credit union if they also become a member of one of their affiliated organizations, which also allow anyone to join.

    2.00% – 3.50%

  • Term

    6 months - 5 years

Why Connexus Credit Union?

Connexus has terms from six months to five years, plus bump-up certificates that let you add money. Rates aren't stellar, but are above the national average. However, its 17-month special certificate has a rate of 4.30% — higher than anything on our list of best 18-month CDs. You'll need a minimum deposit of $5,000 to open any of these, which is on the high end. Anyone can join Connexus by making a one-time $5 donation to the Connexus Association.

If you don’t see a credit union on this list that you can — or want to — join, don’t despair. There are over 4,500 federally insured credit unions in the U.S. Look around your town and you may find a local credit union that not only pays you a great rate, but also supports your community in meaningful ways.

How to shop for a CD or share certificate

  1. Choose the right term

    Pick a CD term that matches when you'll need the funds. For example, if it's spring and you're going on vacation in the summer, a three-month term could make sense.

  2. Decide on a deposit

    Know how much money you can afford to lock away at once.

  3. Research rates

    This page is a great place to start, but many credit unions restrict membership to specific states or counties. Search for "open" credit unions (which let anyone join) and credit unions near you, then compare APYs. Community credit unions might not have the best search engine optimization, so you might need to dig deeper into your search results to find them.

  4. Read Bankrate’s reviews

    When you've narrowed your list, check out our credit union reviews. Bankrate reads the fine print and tracks industry data so we can point out both unusual perks and possible downsides, and we've reviewed many larger credit unions.

  5. Make a choice

    Of the credit unions with minimum deposits within your budget, pick the one that offers the best rate with no deal-breaking catches. If you plan on doing all of your banking with the credit union, make sure their other services meet your needs, too.

Pros and cons of credit union CDs

Pros

  • Checkmark Icon

    Member ownership means better rates: Unlike banks, credit unions are owned by the people who bank there. The credit union’s "surplus" (profit) is returned as higher rates on deposits and lower rates on loans.

  • Checkmark Icon

    Community focus: Most credit unions restrict membership to certain counties or states, which means that your deposits stay local and go to supporting small businesses and neighbors. For example, the San Diego Credit Union supports over 75 non-profit organizations in its geographic service region.

Cons

  • Membership is often restricted: Some credit unions are open to everyone. But you won't qualify for many of the great rates on this page because many credit unions restrict membership to specific populations.

  • Can't open just a CD: You become a credit union member by purchasing at least one “share” of the institution, often for $5, that you deposit into a savings account. You don't have to use this as your main savings account, but make sure to read the accounts' terms for any fees.
