PenFed and Navy Federal at a Glance
Navy Federal Credit Union and PenFed Credit Union are the two largest military-affiliated credit unions in the country, but they serve different membership bases and compete hardest on different products. Navy Federal restricts membership to the Department of Defense and Coast Guard community. PenFed opened its doors to anyone who opens a savings account, no service required.
Navy Federal is the largest credit union in the United States by assets and membership, built specifically around military life, with branches on or near many bases and a deep bench of military-focused programs. PenFed (Pentagon Federal Credit Union) started the same way, serving military and government employees, but changed its charter years ago to allow open membership, which broadened its footprint well beyond the military community.
Veterans who qualify for both often keep accounts at each and shop both for loans, since neither one wins every category. This guide compares them on the dimensions that matter most: membership rules, VA loan pricing, auto loans, savings products, and branch access.
PenFed vs Navy Federal: Side-by-Side Comparison
The table below lines up both credit unions on what military members and veterans ask about most.
| Dimension | PenFed | Navy Federal |
|---|---|---|

| VA loans | Originates VA purchase and refinance loans directly | Originates VA purchase and refinance loans directly; high VA loan volume nationally |
| Auto loans | Long-standing reputation for competitive new and used auto rates | High-volume auto lender with military-specific perks like overseas vehicle purchase support |

| Savings and CD yields | Regularly ranks among the more competitive credit union CD rates | Competitive money market and CD tiers, plus military-specific savings tools |
| Overseas / deployment support | Standard online and phone banking, less military-specific infrastructure | Deployment-focused features: fee-free overseas ATMs at many locations, deployed-member support |
| Credit cards | Known for flat-rate cash-back and travel cards with no annual fee options | Broad card lineup with military-family-oriented rewards categories |
Membership Eligibility: Who Can Join
PenFed membership is open to anyone; Navy Federal membership requires a Department of Defense or Coast Guard connection. This is the single biggest structural difference between the two.
To join Navy Federal, you (or an immediate family member) need to be active duty, a veteran, a retiree, a DoD civilian employee, or a Coast Guard member. Our Navy Federal vs USAA comparison covers eligibility overlap with USAA in more detail, since the two share a similar military-only structure.
PenFed still markets to the military and government community and offers a PenFed Foundation that funds military causes, but membership itself no longer requires any service connection. You can join by opening a share savings account, typically with a small minimum deposit, which makes PenFed available to spouses, adult children, and civilian friends who do not otherwise qualify for a military-only credit union.
VA Loans and Mortgages
Both PenFed and Navy Federal originate VA purchase and refinance loans directly, and both are large enough to be competitive, so the better rate is decided by your loan file, not by brand loyalty. Neither credit union publishes a standing rate advantage over the other.
The most reliable way to compare is to request a Loan Estimate from each on the same day, then compare the interest rate, discount points, lender fees, and closing costs line by line. Rates move daily and can also vary by loan amount, occupancy type, and your credit profile. For general VA loan mechanics, including funding fee rules and entitlement, see our VA home loan guide.
Because VA loans require no down payment and no private mortgage insurance, the lender-specific variables that matter most are the interest rate, points, and how efficiently each credit union processes your file to closing.
Auto Loans
PenFed has built a long-standing reputation for competitive new and used auto loan rates, while Navy Federal runs one of the highest-volume auto lending programs in the credit union industry with military-specific perks. Both are worth a quote before you finance through a dealer.
Navy Federal adds military-relevant features like support for overseas vehicle purchases and loans for buying a car while stationed outside the continental United States. PenFed's auto loan program is open to any member and is frequently cited in third-party rate comparisons as one of the more competitive credit union options nationally.
Auto loan pricing depends heavily on your credit score, the vehicle's age, and the loan term, so pull a real rate quote from both before committing, and compare against a dealer-arranged loan too.
Savings, Checking, and CDs
Neither credit union charges a monthly maintenance fee on its core checking account, and both offer competitive savings and CD tiers compared to large national banks. The differences show up in the details.
Navy Federal offers a range of savings products, including tiered money market accounts and military-specific tools like automatic savings around deployments. PenFed has regularly appeared among the more competitive credit unions for CD annual percentage yields, particularly on shorter terms, though exact rates shift with the broader rate environment.
Both participate in nationwide surcharge-free ATM networks, so day-to-day cash access is comparable even where physical branches are not.
Branch Access and Customer Service
Navy Federal has a much larger physical branch network, including locations built specifically to serve members on or near military installations; PenFed operates far fewer branches and leans on digital banking. If in-person service matters to you, that gap is worth weighing heavily.
Navy Federal's branch presence extends overseas near some military communities and includes extended hours at many locations around military paydays. PenFed members who want in-person service more often rely on shared branching networks rather than PenFed's own branches.
Both offer 24/7 phone support and mobile apps with mobile check deposit, bill pay, and person-to-person transfers, so routine digital banking is comparable even though the in-person experience is not.
Verdict: Which Should You Choose?
Choose Navy Federal if you want the largest branch network in the military-credit-union space, deployment-specific banking features, and you already qualify through DoD or Coast Guard ties.
Choose PenFed if you want open membership for family members who do not qualify for a military-only institution, or if you are specifically shopping for a competitive auto loan or CD rate and want a straightforward online-first experience.
If you qualify for both, there is little downside to joining each and using them for what they do best; many military families keep a Navy Federal account for everyday banking and branch access, then shop PenFed for auto loans or CDs.
