How We Evaluate Credit Unions

The ratings below assess credit unions across five dimensions:

1. Savings rates — APY on share savings, high-yield savings, and share certificates vs national average
2. Loan rates — Auto loans, personal loans, and mortgages vs national bank average
3. Fees — Monthly maintenance fees, overdraft fees, and ATM fees
4. Access — Branch count, ATM network, shared branching participation
5. Digital experience — Mobile app quality, online account opening, digital features

Methodology note: institutions below are included as informative examples for comparison purposes, not as a ranked, exhaustive “best” list. Inclusion does not constitute a recommendation. Confirm current rates, fees, and eligibility directly with each institution.

Best Credit Union for Military: Navy Federal Credit Union

Navy Federal Credit Union is the largest credit union in the US by assets (more than $200 billion as of Q1 2026) and membership (15.5 million+ as of March 2026). It consistently earns top marks for auto loan rates, mortgage rates, and member satisfaction.

Limitation: Membership is strictly limited to military-affiliated individuals. If you don’t qualify, an open-membership credit union such as Alliant or Connexus is an alternative.

Why it stands out:

• A national credit union to get a comparison quote from when you shop for an auto loan or mortgage

Limitation: We could not read PenFed’s own site for this update, so confirm its current rates, fees and eligibility there before applying.

Best Regional Credit Union: BECU (Boeing Employees Credit Union)

BECU is the largest credit union in Washington State (approximately $29 billion in assets, more than 1.5 million members as of year-end 2025) and consistently earns high member satisfaction ratings in the Pacific Northwest.

• Strong online and mobile banking

Limitation: Smaller asset base means fewer branches; primarily an online credit union.

Credit Unions vs Banks: Rate Comparison

The NCUA compares national average rates at credit unions and banks each quarter. For December 26, 2025, credit unions averaged less than banks on regular savings (0.19% vs. 0.32%) but more on 1-year certificates (2.95% vs. 2.29%), and charged less on a 60-month new car loan (5.44% vs. 7.41%). Individual credit unions and online banks can pay far more than these averages — the top savings rate we track was 4.05% at Bread Savings on October 14, 2026.

National averages from the NCUA’s Credit Union and Bank Rates 2025 Q4 table; they change with Federal Reserve policy. Confirm current rates directly before making decisions.

How to Choose the Best Credit Union

1. Confirm eligibility first — Use the NCUA locator or aSmarterChoice.org to find credit unions you can actually join.
2. Match to your primary need — Savings rates, auto loans, mortgages, or checking account quality.
3. Check access — Does it have branches near you? Does it participate in CO-OP shared branching?
4. Evaluate the app — Download the app and read recent reviews before committing.
5. Compare fees — Look at monthly maintenance fees, overdraft fees, and foreign transaction fees.
6. Read the fine print on rates — Some high APY accounts require minimum transactions, minimum balances, or direct deposit.
