Best Credit Unions of 2026

Credit unions offer some of the best rates on savings accounts, auto loans, and personal loans — often beating traditional banks by a wide margin. Because they are member-owned and not-for-profit, they return earnings to members in the form of higher deposit rates and lower loan rates.

What Is a Credit Union?

A credit union is a member-owned financial cooperative. When you open an account, you become a partial owner. Credit unions are regulated by the National Credit Union Administration (NCUA), which insures deposits up to $250,000 — the same protection FDIC provides for bank deposits.

How to Join a Credit Union

Most credit unions that appear on best-of lists are now open to anyone in the U.S. Common paths to membership include:

Making a one-time donation to a partner charity or association (typically $5–$15)
Living, working, or attending school in a specific area
Being employed by a qualifying employer
Being related to an existing member

Once you qualify, you typically open a share savings account with a small minimum deposit (often $5–$25) that establishes your membership.

What to Look for in a Credit Union

NCUA insurance: Always confirm deposits are federally insured
ATM network: Look for shared branching or ATM fee reimbursements
Mobile app quality: Essential for day-to-day banking
Rates: Compare savings, loan, and CD rates against current national averages
Membership eligibility: Confirm you can qualify before applying

Bottom Line

Credit unions consistently beat traditional banks on loan rates and often match or beat online banks on savings rates. If you qualify for Navy Federal, that should be your first stop. For everyone else, Alliant, PenFed, and Connexus are strong all-around choices with open membership.
