A credit union is a member-owned, not-for-profit financial institution that offers the same products as a bank — checking accounts, savings accounts, auto loans, mortgages, and credit cards — but is structured to serve its members rather than generate profits for shareholders. As of 2026, there are approximately 4,600 federally insured credit unions in the US, serving over 140 million members. Because profits return to members, credit unions typically offer higher savings rates, lower loan rates, and fewer fees than traditional banks.
Credit Unions vs Banks: Key Differences
| Feature | Credit Union | Bank |
|---|---|---|
| Ownership | Member-owned (you own a share) | Shareholder-owned |
| Profit motive | Not-for-profit — profits returned to members | For-profit |
| Deposit insurance | NCUA (up to $250,000 per category) | FDIC (up to $250,000 per category) |
| Eligibility | Must meet field of membership | Open to all |
| Savings rates | Typically higher | Typically lower |
| Loan rates | Typically lower | Typically higher |
| Fees | Fewer and lower | More common |
| Branch network | Usually regional or niche | Often nationwide |
| Digital banking | Improving, but often behind big banks | Generally more advanced |
| Customer service | Member-focused, often higher satisfaction | Varies widely |
How Credit Unions Work
Credit unions operate as financial cooperatives. When you join, you purchase a “share” in the institution — typically a $5–$25 deposit into a share savings account — which makes you a part-owner with voting rights. Every member has one vote regardless of how much money they have on deposit, and members elect a volunteer board of directors.
Because they do not pay dividends to outside shareholders, credit unions can pass savings back to members through:
- Higher dividend rates on savings accounts and CDs (called share certificates)
- Lower interest rates on auto loans, personal loans, and mortgages
- Reduced or eliminated fees on checking accounts and ATM withdrawals
The average credit union savings rate consistently runs 0.10–0.40 percentage points higher than the national bank average. On a $25,000 emergency fund, that difference compounds to $25–$100 per year in extra interest.
NCUA Insurance: How Your Money Is Protected
Federal credit unions and most state-chartered credit unions are insured by the National Credit Union Administration (NCUA) — the credit union equivalent of the FDIC. Coverage works identically:
- Up to $250,000 per share owner, per institution, per account category
- Single accounts, joint accounts, IRAs, and trust accounts each receive separate $250,000 coverage
- Coverage applies even if the credit union fails — the NCUA pays insured funds typically within a few business days
To verify a credit union is NCUA-insured, look for the NCUA logo on its website or use the NCUA’s online locator. For full coverage details, see NCUA insurance explained.
Types of Credit Unions
| Type | Who It Serves | Examples |
|---|---|---|
| Employee / Occupational | People who work for a specific employer or industry | Boeing Employees CU, First Tech FCU (tech), Delta Community CU |
| Community / Geographic | People who live or work in a specific area | BECU (Washington State), Suncoast CU (Florida) |
| Military | Active duty, veterans, and family members | Navy Federal CU, PenFed CU |
| Association / Faith-based | Members of a qualifying organization or group | Lake Michigan CU, Alliant CU |
| Open membership | Anyone — often through a $5–$25 partner org donation | Alliant CU, PenFed CU, Connexus CU |
How to Join a Credit Union
- Check your eligibility — Your employer, location, military status, or a family member’s membership may qualify you. Use the NCUA locator or aSmarterChoice.org to find credit unions you can join.
- Choose a credit union — Compare savings rates, loan rates, branch/ATM access, and app quality. See how to choose the best credit union for a full framework.
- Meet membership requirements — If no employer or location qualifier applies, many credit unions let you join a partner nonprofit for $5–$25.
- Open a share savings account — Fund it with the minimum deposit (usually $5–$25). This share is your membership stake.
- Open additional accounts — Once you’re a member, you can open checking accounts, apply for loans, and use any other services.
Most credit unions let you complete this process entirely online in under 15 minutes.

Shared Branching: Using Other Credit Unions’ Branches
Most credit unions participate in shared branching networks — primarily the CO-OP Shared Branch network with 5,600+ locations and 30,000+ ATMs. This means as a member of one participating credit union, you can conduct most transactions — deposits, withdrawals, loan payments — at any other participating credit union branch nationwide.
This largely eliminates the branch access disadvantage of smaller credit unions.
