Credit unions are member-owned cooperatives; banks are for-profit corporations owned by shareholders

A credit union is a financial institution owned by its customers, called members. A bank is owned by shareholders and run to generate profit for those owners. This one difference shapes almost everything else about how each one works — the fees they charge, the interest rates they offer, who makes decisions about lending, and where your money goes when you deposit it.

When you join a credit union, you become a part-owner. When you open an account at a bank, you become a customer. That distinction matters because credit unions return profits to members through lower fees, higher savings rates, and better loan terms. Banks distribute profits to shareholders, which can mean higher fees for you and lower rates on savings accounts.

Both are insured by the federal government — banks through the FDIC (Federal Deposit Insurance Corporation) and credit unions through the NCUA (National Credit Union Administration) — so your deposits up to $250,000 are protected either way.

Key Takeaways

  • Credit unions are owned by members and return profits to them; banks are owned by shareholders and distribute profits to investors.
  • Credit unions typically charge lower fees and offer higher interest rates on savings, but may have fewer branches and ATMs than large banks.
  • Credit unions often have stricter lending standards but may work with members who have lower credit scores; banks use more automated lending decisions.
  • Both credit unions and banks are federally insured up to $250,000 per account, so your money is protected at either type of institution.
  • Credit union membership usually requires you to meet a specific criterion — working for a certain employer, living in a certain area, or belonging to a certain organization.

Fees and interest rates: where credit unions typically cost less

Credit unions charge lower monthly maintenance fees than banks, often zero. Many credit unions have no minimum balance requirement to open a checking account, while banks frequently require $500 to $1,500 to avoid a monthly fee. If you carry a low balance or make frequent transfers, a credit union checking account will almost certainly cost you less.

Savings account interest rates are higher at credit unions. Because credit unions return profits to members rather than shareholders, they pass higher rates directly to depositors. The difference compounds over time — a credit union savings account earning 4.5% annually will grow faster than a bank account earning 2%, even if both started with the same deposit.

Credit unions also charge lower fees for overdrafts, wire transfers, and ATM use outside their network. Some credit unions reimburse out-of-network ATM fees entirely. Banks, especially large national chains, charge $3 to $5 per out-of-network ATM withdrawal and $25 to $35 per overdraft.

Loan terms and lending decisions

Credit unions often offer lower interest rates on auto loans, personal loans, and mortgages than banks do. Because they are not trying to maximize shareholder profit, they can lend at rates closer to their actual cost of funds. A credit union auto loan might be 1% to 2% lower than a bank loan for the same borrower and term.

Credit unions are more likely to work with borrowers who have lower credit scores or limited credit history. A loan officer at a credit union may review your full financial picture — your job stability, savings history, and reason for the loan — rather than relying only on a credit score. Banks use more automated underwriting, which means a low score often results in an automatic decline or a much higher rate.

The trade-off is that credit unions may take longer to process loans and may have stricter debt-to-income limits. A bank can approve a loan in hours; a credit union may take several days or a week because a human reviews the application.

Branches, ATMs, and access to your money

Large national banks have thousands of branches and ATMs across the country. Credit unions typically have far fewer locations — often just a handful in one region. If you travel frequently or move often, a large bank's branch network is more convenient.

Many credit unions belong to shared branching networks and ATM cooperatives that expand access without the credit union owning the location. A credit union member can often walk into another credit union's branch and conduct transactions, or use ATMs in a nationwide network. Check whether your credit union participates in these networks before you join.

Online banking and mobile apps at credit unions have improved significantly in recent years. Most credit unions now offer the same digital tools as banks — mobile check deposit, bill pay, account transfers, and 24/7 access. If you do most of your banking online, the smaller branch network matters less.

Membership requirements and who can join

You cannot simply walk into a credit union and open an account. Credit unions serve specific groups — employees of a particular company, residents of a certain county, members of a union or professional association, or people who work in a specific industry. You must meet the membership criterion to join.

Some credit unions have broad membership fields. A credit union might serve "anyone who lives or works in County X" or "anyone employed in healthcare." Others are narrow — serving only employees of one large employer or members of one organization. Before you assume you cannot join a credit union, search online for credit unions in your area and check their membership rules.

Once you meet the membership criterion, you usually pay a small one-time membership fee (often $5 to $25) and maintain a minimum savings deposit (often $25 to $100). This deposit makes you a member-owner; it is not a monthly fee.

Technology and customer service differences

Large banks invest heavily in technology and offer the most advanced digital tools — real-time payment apps, AI-powered budgeting, and integration with third-party financial services. Credit unions are catching up but often lag behind in cutting-edge features.

Credit union customer service is typically more personal. You are more likely to speak with a human who knows your account and can make exceptions or work with you on problems. Banks route you through automated systems and call centers where representatives follow strict scripts and have less authority to bend rules.

Credit unions may have limited customer service hours — often closing at 5 or 6 p.m. and closed on weekends. Banks, especially large chains, often have 24/7 phone support and weekend hours. If you need help outside standard business hours, a bank is more accessible.

Safety and insurance protection

Both credit unions and banks are federally insured. The FDIC insures bank deposits; the NCUA insures credit union deposits. Both cover up to $250,000 per depositor, per account type, per institution. Your money is equally safe at either one.

Credit unions have a lower failure rate than banks historically, partly because they are smaller and more conservative in their lending. However, both types of institutions are regulated and examined regularly by federal agencies. The risk of losing money due to institutional failure is extremely low at either a bank or a credit union.

Frequently Asked Questions

Can I have accounts at both a bank and a credit union?

Yes. Many people maintain accounts at both. You might use a bank for its branch network and advanced technology, and a credit union for its lower fees and better savings rates. Your deposits at each are insured separately up to $250,000.

What happens to my money if a credit union fails?

The NCUA takes over the credit union's operations and protects your deposits up to $250,000, just as the FDIC does for banks. In rare cases, deposits are transferred to another credit union. Your money is protected the same way it would be at a bank.

Are credit unions harder to get loans from?

Credit unions often work with borrowers banks reject, especially those with lower credit scores or shorter credit histories. However, they may require more documentation and take longer to decide. If you have good credit, you might get a better rate at a credit union; if you have poor credit, a credit union may be your best option.

Do I need to use a credit union's ATM to avoid fees?

It depends on the credit union. Some reimburse out-of-network ATM fees; others charge $1 to $3 per withdrawal. Many participate in shared ATM networks that give you access to thousands of ATMs nationwide. Ask your credit union about its ATM policy before you join.

Can I switch from a bank to a credit union?

Yes, if you meet the membership requirement. You can open a credit union account while keeping your bank account open, then gradually move your direct deposits and automatic payments over. There is no penalty for closing a bank account, though you should give your employer time to update your direct deposit information.
