The core difference: who owns the institution and who gets the profit

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 your deposit if it chooses to. A credit union is a nonprofit cooperative owned by its members—you, if you have an account 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 shapes nearly everything else 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 model is inherently better; they serve different priorities.

Key Takeaways

  • Banks are for-profit corporations owned by shareholders; credit unions are nonprofits owned by their members, which affects interest rates and fees.
  • Banks typically offer more branches and services; credit unions often have lower fees and better rates but fewer locations.
  • Both are insured up to $250,000 per account by the FDIC (banks) or NCUA (credit unions), so your deposits are equally protected.
  • Banks can deny you membership based on credit or banking history; credit unions have membership requirements but often accept people banks reject.
  • Credit unions may limit access to shared branching networks, while banks operate their own nationwide branches.

How interest rates and fees differ in practice

Credit unions typically offer higher rates on savings accounts and certificates of deposit because they return profit to members instead of shareholders. A credit union savings account might pay 0.50% APY while a bank's pays 0.10% on the same balance. This difference compounds over time, especially on larger deposits.

Loan rates follow the same pattern. A credit union car loan might be 2 percentage points lower than a bank's offer for the same borrower. On a $25,000 loan, that difference means hundreds of dollars in interest paid over the life of the loan.

Fees also tend to be lower at credit unions. Many credit unions charge no monthly maintenance fee, no overdraft fee, or no ATM fee—or charge significantly less than banks do. Banks, especially large national ones, often charge $12 to $15 monthly maintenance fees and $30 to $35 per overdraft. Credit unions frequently waive these entirely or charge $5 to $10.

Branch access and where you can do your banking

Banks operate their own branch networks. A large national bank like Chase or Bank of America has thousands of branches where you can deposit checks, withdraw cash, or speak to a banker. You can walk into any branch and conduct business, regardless of which location you opened your account at.

Credit unions have fewer branches because they are smaller and nonprofit. A local credit union might have 5 to 10 branches in your region. To solve this, credit unions participate in shared branching networks—agreements where you can use branches of other credit unions in the network. A credit union member might access 30,000 shared branches nationwide, but not all credit unions participate equally, and not all locations offer all services.

ATM access works similarly. Banks own their ATM networks. Credit unions participate in shared ATM networks, often with thousands of ATMs available, but again with variation by institution. If you travel frequently or need daily in-person banking, a bank's branch density may matter more to you than a credit union's rates.

Who can open an account and membership requirements

Banks accept almost anyone with a valid ID and Social Security number, though they may check your banking history through ChexSystems (a banking record database). If you have unpaid overdrafts or fraud flags, a bank might deny you, but most people are accepted.

Credit unions have membership requirements—you must meet a specific criterion to join. Common ones include living or working in a certain county, working in a specific industry, being a student at a particular school, or being a family member of an existing member. These requirements exist because credit unions are member-owned cooperatives, not open to the public.

The practical effect: credit unions often accept people banks reject. If you have a poor banking history or no credit history, a credit union may open an account for you when banks will not. You straightforward need to meet their membership criterion, which is often broad enough that most people may have access to through some connection.

Insurance protection and what happens if the institution fails

Both banks and credit unions carry deposit insurance, but through different agencies. Banks are insured by the Federal Deposit Insurance Corporation (FDIC). Credit unions are insured by the National Credit Union Administration (NCUA). Both cover up to $250,000 per depositor, per account type, per institution.

This means your money is equally protected whether you bank at a large national bank or a small local credit union. If the institution fails, the insurance agency steps in and returns your deposits. The insurance limit applies per account type—a savings account and a checking account are separate, so you could have $250,000 in each and be fully covered.

In practice, bank and credit union failures are rare. The last major bank failure in the United States was in 2023; credit union failures are even less common. Insurance exists as a safety net, not because either type of institution is inherently risky.

Technology and online banking features

Large banks typically offer more sophisticated online and mobile banking tools because they have larger technology budgets. You might find features like advanced budgeting tools, investment platforms, or seamless integration with third-party apps at a major bank that a credit union does not offer.

Credit unions have improved their technology significantly in recent years, and many now offer competitive mobile apps and online platforms. Smaller credit unions may lag behind, but this varies widely. Before choosing a credit union, check whether its online banking meets your needs—some are quite robust, others are basic.

Both types of institutions now offer mobile check deposit, bill pay, and account transfers. The difference is usually in the polish and breadth of features, not in whether the core services exist.

Loan approval and borrowing terms

Banks use standardized lending criteria and algorithms. Your credit score, income, and debt-to-income ratio determine whether you are approved and at what rate. The process is fast and impersonal; a computer scores your process and a decision comes back quickly.

Credit unions often use relationship-based lending. A loan officer may review your full financial picture, your history with the credit union, and your circumstances before deciding. This can mean approval for people with lower credit scores or unusual income situations that a bank's algorithm would reject. It can also mean slower decisions because a human is involved.

Credit unions also tend to offer more flexible terms. If you need a longer repayment period or a smaller loan amount, a credit union may customize the terms. Banks offer standardized products with less flexibility.

Frequently Asked Questions

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

Both are equally safe. The FDIC insures banks and the NCUA insures credit unions, each up to $250,000 per account. Both agencies have the backing of the federal government. Your deposits are protected the same way at either institution.

Can I use a credit union ATM if I bank at a bank?

Not directly. You can only use ATMs owned by your own bank or by banks in its network. Credit union members can use credit union ATMs through shared networks, but bank customers cannot access those networks. Some banks and credit unions have reciprocal agreements, but this is not standard.

Do credit unions have better rates than banks?

Credit unions typically offer higher savings rates and lower loan rates because they return profit to members rather than shareholders. However, some online banks (which are for-profit but have low overhead) offer rates competitive with or better than credit unions. Compare specific institutions rather than assuming one type is always better.

What happens if I move and my credit union is not nearby?

You can continue banking with your credit union through online and mobile banking, shared branching networks, and shared ATMs. Many credit unions also allow you to conduct most business by mail or phone. If you need frequent in-person service, you might switch to a bank or a credit union with branches in your new location.

Can a credit union deny me membership?

Yes, if you do not meet the membership requirement—for example, if you do not live in the service area or work in the specified industry. However, most credit unions have broad membership criteria, so you may may have access to through a family member or a secondary connection even if your primary connection does not explore.
