Best 1-year credit union CD rates for September 2025

Rates updated between Sept. 8 and Sept. 14

At Bankrate we strive to help you make smarter financial decisions. Though our partners compensate us from links on this page, we maintain editorial integrity, and partners don't influence our product evaluations. Here's how we make money and here is our advertiser disclosure.

To find the best rate on a one-year certificate of deposit at a credit union, it pays to shop around and compare yields. It also pays to read about credit unions’ membership policies, to see if you’re eligible to join. Below, we list the most competitive one-year CDs from credit unions that Bankrate reviews. Note that credit unions often call their version of CDs “share certificates.” They’re pretty much the same: both are designed to hold your funds for a set amount of time, and they usually pay a fixed annual percentage yield (APY).

Rating: 4 stars out of 5

With a minimum deposit of $500, you’ll earn 4.15 percent APY, which is highly competitive but there are five total balance tiers: $500, $20,000, $50,000, $100,000 or $250,000. The highest APY you can earn on this CD is 4.35 percent APY. 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.

American Airlines Federal Credit Union

Rating: 4 stars out of 5

You’ll earn higher rates if you open one of the credit unions’ pre-built CD ladders (multiple share certificates with different terms) than you do with individual certificates.

Star One Credit Union

Rating: 3 stars out of 5
3.5

Overview

Star One Credit Union only offers three CD terms: six months, one year and two years. The rates on all three are all pretty close to each other and the credit union helpfully calculates the interest you’ll earn with each on a $5,000 deposit, in case that number can help you make a decision on which certificate to open.

To open a share certificate, you must be a member of a credit union that offers them. Credit unions often serve a specific community, geographic area, type of employee, or association, so you’ll need to meet membership requirements.

What is a 1-year credit union CD or share certificate?

Credit union share certificates are similar to certificates of deposit (CDs) offered by banks. The main difference is that CDs are products offered by for-profit banks, while share certificates are offered by member-owned, not-for-profit credit unions. For that reason, “share certificate” and “credit union CD” are often used interchangeably. Also, whereas CDs earn interest, share certificates earn dividends, but the effect for the saver is the same. By looking at annual percentage yields (APYs), consumers can compare interest and dividends on an apples-to-apples basis.

The average one-year CD yield is 2.03 percent APY, according to Bankrate’s survey of institutions.

The chart below shows how much interest you would earn for different CD terms.

How to find the best 1-year share certificate for you

Compare FDIC-insured banks and National Credit Union Administration (NCUA) credit unions to find the best one-year CD for you. You can find the best one-year share certificate by: 

  • Looking at APYs
  • Comparing financial institution ratings
  • Choosing minimum opening deposit requirements based on how much money you want to deposit into a CD
  • Understanding the early withdrawal penalties

Banks or credit unions: Who offers better rates?

Online-only Federal Deposit Insurance Corp. (FDIC) banks tend to offer higher yields than National Credit Union Administration (NCUA) credit unions for savings accounts – based on the institutions that Bankrate tracks. 

But for one-year CDs, the top online bank and the top credit union have similar APYs.

Some of the most competitive APYs available on CDs can be found on share certificates at credit unions so it is important to include them in your search. Credit unions can offer their members the convenience and friendly service of local branch access while earning a competitive return.
