The core difference: who owns the institution and who it serves
A bank is a for-profit business owned by shareholders — people or companies who bought stock in it. The bank's goal is to make money for those owners. A credit union is a nonprofit cooperative owned by its members — the people who hold accounts there. The credit union's goal is to serve its members, not generate profit for outside investors.
This ownership structure shapes nearly everything else about how each institution works. When a bank makes money, some of it goes to shareholders as dividends. When a credit union makes money, it typically returns that money to members through lower fees, better interest rates on savings, or lower rates on loans. You are not just a customer at a credit union — you are technically a part-owner.
Both banks and credit unions are insured by the federal government, so your money is protected the same way at either one. But the way they operate, who they serve, and what they charge you can be quite different.
Key Takeaways
- Credit unions are member-owned nonprofits that return profits to members through better rates and lower fees, while banks are for-profit businesses owned by shareholders.
- Credit unions often have lower fees and better savings rates, but may have fewer branches and ATMs than large banks.
- Credit unions typically serve a specific community or group — your employer, your union, your neighborhood, or your profession — while banks serve anyone who walks in.
- Both are federally insured, so your deposits are protected equally at either type of institution.
- Joining a credit union usually requires membership in the group it serves, though some credit unions have opened to broader communities in recent years.
Fees and interest rates: where the ownership difference shows up in your wallet
Credit unions typically charge lower fees than banks. Monthly account maintenance fees, overdraft fees, and ATM fees are often lower or nonexistent at credit unions. Savings accounts at credit unions often pay higher interest rates on your balance. Loans — car loans, personal loans, mortgages — often carry lower interest rates at credit unions than at banks.
This is not because credit unions are more generous. It is because they do not need to generate profit for shareholders. When a credit union takes in money from fees and interest, it can afford to return more of that money to members. A bank, by contrast, must set aside money for shareholders, which means it needs higher fees and lower rates to stay profitable.
That said, not every credit union is cheaper than every bank. Some large banks offer competitive rates and low fees to attract customers. Some credit unions charge more than you might expect. The best approach is to compare the specific accounts and loans you need at the institutions available to you.
Membership requirements: who can join
Banks are open to anyone. You can walk in with an ID and open an account. Credit unions, by contrast, typically require you to be a member of the group they serve. That group might be employees of a specific company, members of a labor union, residents of a particular county, people who work in a certain industry, or members of a religious organization.
Some credit unions have broadened their membership over time. A few now serve anyone in a geographic area, or anyone who works in a field, or anyone who is related to someone already a member. But most still have a defined membership group. Before you can open an account at a credit union, you need to confirm that you meet the membership requirement.
If you do not meet the membership requirement for a credit union you are interested in, you may be able to join a different one. Many people have access to multiple credit unions through their employer, their family, or their community. A tool called CO-OP lets you search for credit unions you might be able to join.
Branches and ATMs: where banks often have the advantage
Large national banks have hundreds or thousands of branches and ATMs across the country. If you travel frequently or move often, a big bank's network can be convenient. Most credit unions have far fewer locations — often just a handful in one region.
However, credit unions have created networks to work around this. The CO-OP Network and Allpoint are shared ATM networks that let credit union members use ATMs at other credit unions and partner locations without paying a fee. Many credit unions also offer online banking, mobile apps, and phone support so you can handle most transactions without visiting a branch.
If you need frequent in-person service or live in a place where your credit union has no branch, a bank may be more practical. If you mostly bank online or live near your credit union's location, the limited branch network is usually not a problem.
Loan decisions and customer service: a different approach
Credit unions often make loan decisions based on your full financial picture and your relationship with the institution, not just your credit score. If you have a thin credit history or a recent setback, a credit union may be more willing to work with you than a bank would be. Credit union staff often know their members personally and can explain why a loan was denied or what you need to do to may have access to next time.
Banks, especially large ones, typically use automated systems to make loan decisions. Your credit score, income, and debt-to-income ratio go into a computer, and the computer says yes or no. There is less room for human judgment, which can be faster but also less flexible.
Customer service at credit unions tends to be more personal. You may speak to the same person each time you call, and they may remember your situation from previous conversations. Banks, especially large national ones, often route you through call centers where representatives have no history with you.
Technology and online banking: where banks often lead
Large banks invest heavily in technology and have sophisticated mobile apps, online banking platforms, and digital tools. If you want the latest features — mobile check deposit, bill pay, budgeting tools, investment accounts — a big bank often has more options.
Many credit unions have modernized their technology in recent years, but smaller credit unions may lag behind. Some credit unions use older systems that feel clunky compared to what you get at a major bank. Before you join a credit union, test their online banking and mobile app to see if they meet your needs.
That said, credit unions often partner with technology companies to offer services they do not build themselves. You may be able to access investment accounts, insurance, or other products through your credit union even if the credit union does not provide them directly.
Insurance and safety: the same protection either way
Both banks and credit unions are insured by the federal government. Bank deposits are insured by the Federal Deposit Insurance Corporation (FDIC). Credit union deposits are insured by the National Credit Union Administration (NCUA). Both cover up to $250,000 per account holder per institution.
This means your money is equally safe at a credit union or a bank. If the institution fails, the federal government guarantees your deposits up to the limit. You do not need to worry that a credit union is riskier because it is smaller or nonprofit.
Frequently Asked Questions
Can I have accounts at both a bank and a credit union?
Yes. Many people keep accounts at both. You might use a bank for its branch network and a credit union for its lower fees and better loan rates. There is no rule against having multiple accounts at multiple institutions.
What happens if I leave the group a credit union serves?
You can usually keep your account open even after you no longer meet the membership requirement. For example, if you retire from a company whose credit union you joined, you typically keep your account. Check with your specific credit union about their policy.
Do credit unions offer the same products as banks?
Most credit unions offer checking and savings accounts, loans, and debit cards — the basics. Larger credit unions may also offer mortgages, credit cards, and investment services. Smaller credit unions may have a narrower range of products. Ask about what you need before you join.
Is it harder to get a loan from a credit union if I have bad credit?
Credit unions are often more willing to work with people who have lower credit scores or limited credit history, but it depends on the individual credit union and the type of loan. Some credit unions specialize in lending to people rebuilding credit. It is worth asking.
How do I find a credit union I can join?
Start by checking whether your employer, union, school, or professional association has a credit union. You can also search the CO-OP Network website by location or membership group to see what credit unions serve your area.
