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.

Credit Unions vs Banks: Rate Comparison

As of September 2026, top online savings accounts and credit unions were advertising APYs of roughly 4.00%–4.50%, versus a national average bank savings rate of roughly 0.35%–0.65% depending on the data source (FDIC vs. industry surveys). On a $25,000 balance, that gap is worth roughly $850–$1,100 per year in extra interest — a meaningful but rate-dependent example, not a guaranteed figure.

Account Type National Bank Average Top Credit Union (indicative) Illustrative Annual Difference on $25K
Savings account ~0.35%–0.65% ~4.00%–4.50% ~$850–$1,000
12-month CD ~1.7% ~4.35%–4.75% ~$650–$750
Auto loan (60 mo.) Varies by credit profile Typically below bank average Confirm current rates

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 (5,600+ locations)?
  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.
