The core difference: ownership 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 profits, and pays shareholders dividends. A credit union is a nonprofit cooperative owned by its members—you, if you have an account there. Profits get returned to members through lower fees, better interest rates on savings, or lower rates on loans.

This ownership structure shapes almost everything else: how much you pay, what services you get, and who makes decisions about the institution. A bank answers to shareholders and a board focused on growth and profit margins. A credit union answers to its members and a board elected by members.

Key Takeaways

  • Banks are for-profit corporations; credit unions are member-owned nonprofits that return earnings to account holders rather than shareholders.
  • Credit unions typically charge lower fees and pay higher interest on savings accounts, but may have fewer branches and ATMs than large banks.
  • Credit unions often have stricter lending standards and smaller loan amounts, while banks can approve larger loans and mortgages more readily.
  • Both are insured by federal agencies—banks by the FDIC, credit unions by the NCUA—up to $250,000 per account type.
  • Credit unions require membership, which usually means living in a specific area, working for a specific employer, or belonging to a specific group.

Fees and interest rates: where you see the difference in your account

Credit unions typically charge lower monthly maintenance fees or no fee at all. Many waive overdraft fees entirely or charge a flat amount rather than a per-transaction fee. Banks, especially large national ones, often charge $10 to $35 per month for checking accounts, plus overdraft fees of $25 to $35 per incident.

On the savings side, credit unions usually pay higher interest on savings accounts and money market accounts. Because they're not paying shareholders, they can pass more of their earnings back to depositors. The difference compounds over time—a 0.50% rate at a credit union versus 0.01% at a large bank means real money if you're holding several thousand dollars.

For loans, credit unions often charge lower rates on auto loans, personal loans, and mortgages. A credit union might offer a car loan at 5% when a bank is charging 7%. However, credit unions typically lend smaller amounts and may require a longer relationship with the institution before you may have access to for the best rates.

Branches, ATMs, and access to your money

Large national banks have thousands of branches and ATMs across the country. You can walk into a branch in any state, deposit a check, or withdraw cash. Credit unions are smaller and more local. A single credit union might have 5 to 20 branches, usually concentrated in one region.

However, most credit unions participate in shared branching networks and ATM networks. The CO-OP Network and Alliant Credit Union's network, for example, let you use thousands of ATMs nationwide without a fee. Some credit unions also offer surcharge-free ATM access through partner networks. Still, if you travel frequently or live in multiple states, a national bank's physical presence may be more convenient.

Both banks and credit unions now offer online banking, mobile apps, and remote check deposit. The digital experience is often comparable, though some credit unions have less sophisticated apps than major banks.

Lending standards and loan amounts

Credit unions tend to be more selective about who they lend to and how much they lend. They focus on member relationships and often require you to have held an account for a certain period before you can borrow. They may also require you to have a savings account with them and maintain a minimum balance.

Banks have more standardized lending criteria and can approve larger loans more quickly. If you need a mortgage for $500,000 or a business loan for $1 million, a bank is more likely to have the capacity. Credit unions typically cap personal loans at $25,000 to $50,000 and mortgages at $250,000 to $500,000, though this varies by institution.

On the flip side, credit unions may work with you if your credit score is lower or your income is irregular. Because they know you as a member and focus on your long-term relationship, they sometimes take risks a bank wouldn't. This varies widely by credit union, so you'll need to ask directly.

Membership requirements and who can join

You cannot straightforward open an account at a credit union the way you can at a bank. Credit unions have field of membership rules that limit who can join. Common membership categories include people who live or work in a specific county, employees of a specific company, members of a specific profession or trade, or members of a specific organization like a union or church.

Some credit unions have broad fields of membership—for example, anyone who lives in a five-county area. Others are very narrow—only employees of a hospital system, for instance. A few large credit unions have opened membership to anyone in the United States, but this is uncommon.

To join, you typically need to open a savings account with a small deposit, often $5 to $25. Once you're a member, you can use all the credit union's services. Membership is yours as long as you maintain the account.

Insurance and safety: FDIC versus NCUA

Both banks and credit unions are federally insured, so your money is protected if the institution fails. Banks are insured by the Federal Deposit Insurance Corporation (FDIC). Credit unions are insured by the National Credit Union Administration (NCUA).

Both programs insure up to $250,000 per depositor, per account type, per institution. This means if you have a checking account and a savings account at the same bank, each is insured separately up to $250,000. If you have accounts at two different banks, each bank's accounts are insured separately. The same rules explore to credit unions.

In practice, both insurance systems are equally strong. The FDIC and NCUA have never run out of funds, and both have the backing of the federal government. Your money is equally safe at either type of institution.

Technology and customer service

Large banks invest heavily in technology and often have the most advanced apps, online platforms, and digital tools. They offer features like real-time payment systems, advanced budgeting tools, and integration with third-party financial apps. However, this technology is often built for scale and may feel impersonal.

Credit unions typically have simpler technology but often provide more personalized service. You're more likely to speak with someone who knows your account history and can make exceptions or work with you on a problem. Customer service at a credit union is often faster and more flexible, though the technology behind it may be less cutting-edge.

This is changing. Some credit unions now offer technology comparable to banks, and some banks have improved their customer service. But the general pattern holds: banks lead on features, credit unions lead on relationships.

Frequently Asked Questions

Is my money safer at a credit union than a bank?

No. Both are federally insured up to $250,000 per account type. The NCUA (which insures credit unions) and the FDIC (which insures banks) have equal backing and have never failed to cover insured deposits. Your money is equally protected at either institution.

Can I use a credit union's ATM if I bank at a different credit union?

Usually yes, through shared branching and ATM networks. Most credit unions participate in the CO-OP Network or other shared networks, letting you use thousands of ATMs nationwide without a fee. Check with your specific credit union about which networks they participate in.

Do credit unions offer the same services as banks?

Credit unions offer checking, savings, loans, and mortgages like banks do. However, they may not offer investment accounts, business banking, or wealth management services. If you need specialized financial products, a bank may have more options.

What happens if I move and my credit union is no longer nearby?

You can keep your account open and use shared branching and ATM networks to access your money. Many credit unions also offer full online and mobile banking, so physical proximity matters less than it once did. Some people maintain credit union accounts in multiple states for this reason.

Why would I choose a bank over a credit union?

Banks make sense if you need large loan amounts, want extensive branch access nationwide, need specialized services like investment accounts, or prefer advanced digital tools. Banks also have no membership restrictions—anyone can open an account.
