The core difference: who owns it and who profits

A bank is a for-profit business owned by shareholders. When you deposit money, the bank uses it to make loans and investments, keeps the profit, and pays you interest on deposits if it chooses to. A credit union is a nonprofit cooperative owned by its members—that's you and everyone else who banks there. When a credit union makes profit, it returns the money to members through higher savings rates, lower loan rates, or reduced fees.

This ownership structure changes almost everything about how each institution operates. A bank answers to shareholders who want maximum returns. A credit union answers to members who want the best terms for themselves. Neither is inherently better—it depends on what you need and what each institution near you actually offers.

Key Takeaways

  • Banks are for-profit companies owned by shareholders; credit unions are nonprofits owned by their members, which affects interest rates and fees.
  • Banks typically have more branches and ATMs nationwide, while credit unions often have fewer locations but may offer shared branching networks.
  • Credit unions usually charge lower fees and offer better rates on savings and loans, but banks may have more product variety and faster technology.
  • Both banks and credit unions are insured up to $250,000 per account by the FDIC or NCUA, so your money is equally protected either way.
  • Your choice often comes down to location, the specific rates each institution offers right now, and whether you value personal service or convenience.

How interest rates and fees differ in practice

Credit unions typically offer higher rates on savings accounts and certificates of deposit (CDs) because they return profits to members instead of paying shareholders. A credit union savings account might earn 4.5% APY while a bank's earns 0.5% APY—but this varies month to month and institution to institution. Check the actual rates at the credit union and bank you're considering; don't assume one is always better.

On the loan side, credit unions usually charge lower rates on car loans, personal loans, and mortgages. A credit union car loan might be 6% while a bank charges 8%, but again, this depends on your credit score, the specific lender, and current market conditions. Credit unions also tend to charge lower or no fees for overdrafts, wire transfers, and account maintenance. Banks often charge $30 to $35 per overdraft and $15 to $25 per wire transfer, though some waive these for premium account holders.

The catch: credit unions may have stricter lending standards and smaller loan amounts available. If you need a large mortgage or have poor credit, a bank might approve you when a credit union won't. Banks also compete harder on rates in some markets, so a local bank might beat a credit union's offer on a specific product.

Branches, ATMs, and access to your money

Banks have more physical locations. A major bank like Chase or Bank of America has thousands of branches and ATMs across the country. If you travel frequently or move often, that network matters. Credit unions typically have far fewer branches—often just a handful in one region—but many belong to shared branching networks and ATM co-ops that expand access.

For example, if you join a credit union in Ohio, you might access branches in other states through the CO-OP Network or Alliant Credit Union's shared branching program. You can also withdraw cash at many retail locations like grocery stores and pharmacies. Still, if you need a physical branch visit every week, a local bank is usually more convenient than a credit union.

Online and mobile banking have narrowed this gap. Most credit unions now offer full online banking, mobile apps, and remote deposit capture. Some credit unions have better apps than some banks. If you rarely visit a branch and do most banking on your phone, location matters less than it used to.

Technology, products, and service speed

Banks generally invest more in technology and offer a wider range of products. A large bank can offer investment accounts, brokerage services, credit cards with complex rewards programs, and business banking all in one place. Credit unions typically focus on basic banking: checking, savings, loans, and maybe a credit card. If you want to consolidate all your financial services with one institution, a bank is usually the easier choice.

Banks also tend to process transactions faster. A bank wire transfer might clear the same day; a credit union wire might take one to two business days. Banks have more staff and automation, so customer service calls are answered faster—though you may reach an automated system first. Credit unions often have smaller teams, so wait times can be longer, but you may speak to a person who knows you by name.

For routine banking, the difference in speed is minor. For time-sensitive transactions like a wire transfer before a deadline, a bank's speed can matter. Ask the specific institution about their processing times before you open an account.

Insurance and safety: FDIC versus NCUA

Both banks and credit unions are insured, but by different agencies. Bank deposits are insured by the FDIC (Federal Deposit Insurance Corporation) up to $250,000 per depositor, per account type, per bank. Credit union deposits are insured by the NCUA (National Credit Union Administration) up to the same $250,000 limit. The protection is equivalent—your money is equally safe at either type of institution.

If you have more than $250,000, you can spread it across multiple banks or credit unions to stay fully insured. For example, $250,000 in a checking account at Bank A and $250,000 in a checking account at Bank B are both fully covered. The same applies to credit unions. Joint accounts and retirement accounts have separate insurance limits, so a married couple can insure up to $500,000 in a joint account at one bank.

Neither the FDIC nor the NCUA has ever failed to pay out insured deposits, even during bank failures. This insurance is backed by the U.S. government, so the risk of losing your money due to institutional failure is extremely low at any insured bank or credit union.

Membership requirements and who can join

Banks are open to anyone. You walk in, show an ID, and open an account. Credit unions have membership requirements based on what's called a "field of membership." You might have to work for a specific employer, live in a certain county, belong to an organization, or have a family member who already belongs. Some credit unions have opened their fields of membership to anyone in a geographic area, but many still restrict who can join.

Before you choose a credit union, check whether you meet its membership requirements. If you don't work for the employer or live in the service area, you can't open an account. Some credit unions let you join if you open a savings account with a nonprofit organization they sponsor, but this varies. Banks have no such restrictions, which is one reason they're more accessible to people who move frequently or don't fit a credit union's membership profile.

When to choose a bank versus a credit union

Choose a bank if you need multiple branches and ATMs in different locations, want a wide range of financial products, value fast transaction processing, or don't meet a credit union's membership requirements. Banks are also better if you need a large loan or have credit challenges—they have more flexible underwriting and larger lending capacity.

Choose a credit union if you meet its membership requirements, want lower fees and better rates on savings and loans, prefer personal service, and don't need a large physical network. Credit unions work well if you do most banking online and only occasionally need a branch. They're also a good fit if you value supporting a nonprofit that returns profits to members rather than shareholders.

In practice, many people use both. You might have a checking account at a bank for its convenience and ATM network, and a savings account at a credit union for its higher interest rate. There's no rule against it, and it lets you capture the benefits of each.

Frequently Asked Questions

Is my money safer at a bank or credit union?

Equally safe. Both are insured up to $250,000 per account by federal agencies—the FDIC for banks and the NCUA for credit unions. Neither agency has ever failed to pay out insured deposits. The risk of losing money due to institutional failure is extremely low at any insured institution.

Do credit unions have worse customer service than banks?

Not necessarily. Credit unions often have smaller, more personal teams, so you may speak to someone who knows your account. Banks have more staff and automation, so calls are answered faster but you may reach an automated system first. Service quality depends on the specific institution, not the type.

Can I use a credit union's ATM if I don't live near a branch?

Many credit unions belong to shared branching networks and ATM co-ops that let you access services at other institutions. Ask your credit union which networks it participates in. You can also withdraw cash at many retail locations. Online banking and mobile apps reduce the need for physical access.

What if my credit union doesn't offer a product I need?

You can open an account at a bank for that product while keeping your credit union account for everyday banking. Many people maintain accounts at both types of institutions to access different services and rates. There's no penalty for banking at multiple places.

Do I have to stay with a credit union once I join?

No. You can close your account and move your money anytime. There's no contract or penalty. If you move out of the service area or no longer meet membership requirements, you may be required to close the account, but the credit union will help you transfer your funds.
