You can often find highly competitive yields on share certificates, also called certificates of deposit (CDs), at credit unions. 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. Bankrate has reviewed dozens of credit unions, including some with open memberships, to find the best CDs available.

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).

America First FCU_logo

America First FCU

Rating: 5 stars out of 5
5.0 Bankrate CD score

  • Annual percentage yield

    3.90% – 4.30%

  • 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.

    3.70% – 4.25%

  • Min. deposit to open

    $500

  • Term

    6 months - 5 years

Why Suncoast Credit Union?

Suncoast Credit Union offers CD terms ranging from six months to five years, all with good rates and a reasonable $500 minimum deposit. If you have $100,000 to deposit, you can get higher yields on all of the CDs. Membership is restricted to those who attend school, live, work or worship in a county in Florida that Suncoast Credit Union serves.

Mountain America Credit Union_logo

Mountain America Credit Union

Rating: 4.4 stars out of 5
4.4 Bankrate CD score

  • Annual percentage yield

    3.85% – 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.

    $500

  • Term

Why First Tech Federal Credit Union?

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.

  • 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.

Rate trends for credit union CD rates

Rates on competitive CDs tend to follow moves that the Federal Reserve makes with the federal funds rate. So far, the Fed has held that rate steady in 2026, but competitive rates are inching slowly downwards anyway. 

For CDs, the top online bank and the top credit union have similar APYs.

When comparing average yields across products, credit unions tend to have an edge over traditional banks. However, when looking at the highest-yielding products available nationally, online-only banks most often offer the top rates. It is not solely about yield, however. Regardless of what a single product pays, the financial institution you choose should offer services that fit your financial life.
Stephen Kates, Bankrate financial analyst

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. Use the internet to search for "open" credit unions (which let anyone join) and credit unions near you, then compare APYs. 

  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.

Research methodology

Bankrate researches over 100 banks and credit unions, including some of the largest financial institutions, online-only banks, regional banks and credit unions with both open and restrictive membership policies.

To find the best CD rates at credit unions, we regularly survey CD offerings from the credit unions we monitor and review. We also score these institutions on their APY, minimum deposit requirements, term selection and more. Banks and credit unions receive penalties against their overall scores for each consent decree, penalty in a case brought by a federal regulator or in a certified, federal class-action lawsuit, or adverse federal judgment for harming deposits customers.

The credit unions on this page are selected based on their current highest APY for a CD they offer and their minimum deposit requirements. Learn more about how we choose the best banking products and our methodology for reviewing banks.
