Which one should you pick?
Pick PenFed Credit Union if…
- You can't qualify for Navy Federal Credit Union membership (no military or geo-restricted affiliation)
- You want a credit union that's open to anyone in the U.S. via a simple sign-up
- You prioritize the shortest early-withdrawal penalty available (matters if you might need funds early)
- You want a digital-first experience and don't need physical branches
Pick Navy Federal Credit Union if…
- You qualify directly through residency, employment, or military service
- You value an in-person branch experience in the qualifying geography
- You want a larger institution with a longer track record and broader product menu
- The headline rate at your specific term is higher (re-check at funding time)
Membership eligibility — the gate that decides this
Rate matters; eligibility matters more. A 4.50% rate you can access beats a 4.60% rate you can't. Here's how the membership question plays out:
- PenFed Credit Union: Open to anyone — no military requirement. Practical assessment: anyone in the U.S. who's willing to spend 10-15 minutes online can become an Associate Member and open share certificates the same day.
- Navy Federal Credit Union: Restricted — military, DoD, and family only. Practical assessment: if you don't fit one of the qualifying buckets (employer, residency, military, family), there's no donation-based workaround — you simply can't join, regardless of the headline rate.
Federally insured credit unions are legally required to define a "field of membership" in their bylaws. Some CUs deliberately keep the field narrow (employer-only or single-county); others have written their bylaws to accept anyone via a small donation, free sponsor-organization sign-up, or low-fee Associate Member pathway. Both approaches are NCUA-approved — you get identical insurance, identical accounts, and identical rates whether you join by direct eligibility or Associate Member workaround.
NCUA insurance — identical at both CUs
Both credit unions discussed here are federally insured by the National Credit Union Administration (NCUA) to $250,000 per depositor, per ownership category. That's the same coverage limit and federal backing as FDIC for banks. The two agencies use different funds (the National Credit Union Share Insurance Fund vs. the Deposit Insurance Fund), but both are backed by the full faith and credit of the U.S. government. In 50+ years, no depositor has ever lost insured funds at either institution.
If you have more than $250K in one credit union, expand coverage by titling accounts in different ownership categories: individual ($250K), joint ($250K per co-owner), IRA ($250K), revocable trust ($250K per beneficiary). Each category gets its own $250K limit at each institution. You can also split across both credit unions to double your coverage with zero overlap risk.
When neither one wins — the MYGA case
At the 5-year term, A-rated MYGAs are currently paying around 5.40% — well above either CU's 5-year share certificate.
Math at $250,000 over 5 years (simple annual compounding):
- PenFed Credit Union 5-Year @ 4.00%: $304,163
- Navy Federal Credit Union 5-Year @ 4.10%: $305,628
- 5-Year MYGA @ 5.40%: $325,194
- MYGA advantage vs the higher CU: $19,566
MYGAs are tax-deferred (interest isn't taxed until withdrawal); share certificates are taxed annually as ordinary income. For taxable retirement money you don't plan to touch for 5+ years, the MYGA usually wins on both pre-tax and after-tax math. The trade-off: MYGAs have a surrender schedule, while share certificates have shorter penalty periods. See CD vs MYGA Comparison.
FAQ — PenFed Credit Union vs Navy Federal Credit Union
Which has higher CD rates: PenFed Credit Union or Navy Federal Credit Union?
At the 1-year term as of 2026-06-27, PenFed Credit Union pays 4.30% APY versus Navy Federal Credit Union at 4.40%. At the 5-year term: 4.00% vs 4.10%. Rates change; confirm before opening.
Which is easier to join, PenFed Credit Union or Navy Federal Credit Union?
PenFed Credit Union: Open to anyone — no military requirement. Navy Federal Credit Union: Restricted — military, DoD, and family only. For most non-aligned buyers, the easier-to-join option will be the better default.
Are both NCUA-insured to $250K?
Yes. Both are federally insured credit unions covered by the NCUA up to $250,000 per depositor, per ownership category — the same coverage limit as FDIC.
Which has a better early withdrawal penalty?
PenFed Credit Union: All terms: 30% of dividends earned (proprietary). Navy Federal Credit Union: 90 days (<12mo) / 365 days (>24mo). The shorter penalty wins for anyone who might need flexibility before maturity.
Should I use a CD ladder split between both?
Only if you qualify for both. Otherwise, splitting between any two NCUA-insured credit unions extends your insurance limit and reduces concentration risk. If you have over $250K, splitting is the simplest way to keep all of it insured.
When does a MYGA beat both of these?
At the 5-year term, A-rated MYGAs are currently paying ~5.40% — meaningfully above either CU at the same term. MYGAs also defer tax on interest. For taxable retirement money you don't plan to touch for 5+ years, the MYGA usually wins.
What if neither one fits my membership?
Look at open-eligibility CUs: Alliant ($5 to Foster Care to Success), Bethpage ($5 savings account, no donation), Connexus ($5 Connexus Association donation), or NASA FCU (free National Space Society membership). All four are open to anyone in the U.S.
