A credit union is a member-owned, not-for-profit financial cooperative that offers savings accounts, checking, loans, credit cards, and other banking services to a defined group of eligible members. When you open an account, your deposit buys an ownership share, usually for as little as $5, and you become a part-owner of the institution. Because there are no outside shareholders, any surplus at year-end is returned to the membership in the form of higher savings yields, lower loan rates, and fewer fees.
How a Credit Union Differs From a Bank
The core difference is who the institution answers to. A commercial bank is owned by shareholders and expected to maximize profit for them. A credit union is owned by its depositors, and every dollar of surplus is recycled back into the membership. National rate data consistently shows credit unions paying more on certificates of deposit and charging less on auto loans than the banking industry average.
That structural advantage has limits. Credit unions tend to have fewer physical branches, smaller technology budgets, and narrower product lines than large national banks. If you need complex commercial banking or a global ATM footprint, a major bank may still fit better. For everyday savings, auto loans, mortgages, and credit cards, credit unions are usually competitive on price.
Federal credit unions also operate under a statutory ceiling on loan interest rates. The base cap in the law is 15% per year, but the NCUA Board has authority to raise it when economic conditions warrant and has kept it at 18% since 1987, most recently extending that ceiling through March 2026.1Office of the Law Revision Counsel. 12 USC 1757 – Powers2NCUA. Loan Interest Rate Ceiling Supplemental Info That cap matters most on credit cards, where bank rates routinely climb above 20%.
Member Ownership and Governance
Every member gets exactly one vote regardless of account size. Someone with a $25 savings balance has the same say as someone with $200,000 in certificates. This “one member, one vote” rule is written into federal credit union bylaws and prevents wealthier depositors from steering the institution toward policies that benefit them at everyone else’s expense.3eCFR. Appendix A to Part 701, Title 12 – Federal Credit Union Bylaws
Members elect a board of directors from their own ranks at annual meetings. By law, these directors serve without pay. They can receive health insurance coverage and reimbursement for reasonable expenses, but no salary or bonus for board service.4Office of the Law Revision Counsel. 12 USC 1761 – Management
Every federally insured credit union also has a supervisory committee that acts as the membership’s internal watchdog. It oversees the annual audit, checks that management follows board policy, and must verify member account records at least once every two years.5NCUA. Supervisory Committee General Responsibilities
Not-for-Profit Status
Credit unions are not charities. They handle real money and need to stay solvent. But they operate without a profit motive, and surplus revenue flows back into the membership pool rather than to outside investors.
Federal tax law supports this cooperative model. State-chartered credit unions without capital stock that operate for mutual purposes qualify for tax-exempt status under the Internal Revenue Code.6Office of the Law Revision Counsel. 26 USC 501 – Exemption From Tax on Corporations, Certain Trusts, Etc. Federal credit unions receive a separate exemption as government-chartered entities.7eCFR. 26 CFR 1.501(c)(14)-1 – Credit Unions and Mutual Insurance Funds The exemption applies to the institution, not to you as a member — dividends you earn are still taxable to you as ordinary interest income, and the credit union will send you a Form 1099-INT if you earn $10 or more in a year.8IRS.

Who Can Join
You cannot walk into any credit union and open an account the way you can at a bank. Federal and state regulations require a “field of membership,” a defined group the institution is allowed to serve. In practice, eligibility has expanded broadly enough that most Americans qualify for at least one credit union.
Common Bond Categories
The Federal Credit Union Act recognizes three charter types:9eCFR. Appendix B to Part 701, Title 12 – Chartering and Field of Membership Manual
- Single common bond, based on a shared employer, industry, or membership organization such as a fraternal group or professional association.
- Multiple common bond, where the credit union serves several distinct occupational or associational groups at once.
- Community, where anyone who lives, works, worships, or attends school in a defined geographic area — typically a city, county, or metropolitan region — can join.
Community charters are the broadest type and the reason eligibility feels less restrictive than it once did.
Family Members
If someone in your family already qualifies, you likely do too. Standard federal credit union bylaws extend eligibility to immediate family members of existing members, typically defined as relatives by blood or marriage sharing the same household. Many credit unions have adopted broader definitions that include relatives who don’t live with you, so it is worth asking. Once you are a member, you can usually keep your account even if you move away or change jobs.
Underserved Areas
Federal credit unions can expand their field of membership to reach economically distressed areas that lack adequate banking options. The credit union has to show the proposed area meets economic distress criteria, has significant unmet financial needs, and is underserved by existing banks and credit unions, and it must open a physical branch there within two years of approval.10NCUA.

Finding One You Qualify For
The NCUA maintains a free credit union locator at MyCreditUnion.gov that lets you search by location, employer, or affiliation.11MyCreditUnion.gov. Financial Knowledge and Skills for Every Stage of Your Life Plug in a zip code or employer name and you will see credit unions whose field of membership includes you. Opening an account typically requires a minimum “par value” deposit of around $5, which buys your ownership share and activates your membership.
Is Your Money Safe
The National Credit Union Administration is the independent federal agency that charters and supervises federal credit unions under the Federal Credit Union Act.12Office of the Law Revision Counsel. 12 USC 1751 – Short Title The NCUA administers the National Credit Union Share Insurance Fund, which protects deposits at federally insured credit unions up to $250,000 per depositor per institution. That coverage is backed by the full faith and credit of the United States government, the same guarantee that stands behind FDIC-insured bank deposits.13eCFR. 12 CFR Part 745 – Share Insurance and Appendix
The $250,000 limit applies separately to each ownership category, so you can insure well beyond that amount at a single credit union by spreading deposits across different account types:14NCUA. Share Insurance Coverage
- Individual accounts are insured up to $250,000 in total across all accounts you own alone.
- Joint accounts are insured up to $250,000 per co-owner. A two-person joint account without named beneficiaries carries $500,000 in coverage, separate from each person’s individual account limit.15NCUA. How Your Accounts Are Federally Insured
- IRAs and Keogh retirement accounts are insured up to $250,000 per member, separately from non-retirement deposits.
A married couple who structures accounts across those categories — individual, joint, and retirement — can insure well over $1 million at a single credit union.
Products and Terminology
Credit unions offer most of the same products you would find at a bank, though the terminology reflects your ownership stake. A “share account” is a savings account, a “share draft account” is a checking account, and a “share certificate” is a certificate of deposit. Your deposits are technically shares in the cooperative.
Loan products typically include mortgages, home equity lines of credit, auto loans, personal loans, and credit cards, all subject to the federal interest rate ceiling described above. Many credit unions also offer indirect lending through auto dealerships, where you apply for a credit union loan at the point of sale rather than arranging financing in advance. Credit unions can also lend to member-owned small businesses, though federal law caps aggregate member business lending at roughly 12.25% of total assets for a well-capitalized institution, with exclusions for loans secured by one-to-four-family residential property and loans under $50,000.16GovInfo. 12 USC 1757a – Limitation on Member Business Loans
Branch and ATM Access
The traditional knock against credit unions was that you joined one branch and that was the only place you could bank. Shared branching networks have largely closed that gap. Through the CO-OP network, members of participating credit unions can walk into more than 5,600 branch locations nationwide and conduct deposits, withdrawals, transfers, and balance inquiries as if they were at their home branch. The same network provides access to roughly 30,000 surcharge-free ATMs. You can find nearby locations through the CO-OP ATM and Shared Branch Locator app or by texting your zip code to 91989.
That combined footprint is larger than many major banks’ branch networks. It is not identical to the experience of a single national bank with unified branding and one app, but for routine transactions while traveling or after a move, it works.
