What separates one bank from another

Banks fall into a few distinct categories based on who owns them, what they're allowed to do, and who they serve. The differences matter because they affect what accounts you can open, what interest rates you'll see, what fees apply, and how your money is protected if the bank fails. A commercial bank works differently from a credit union, which works differently from an online bank — and knowing which is which helps you pick the right place to keep your money.

The main dividing lines are ownership structure (who runs it), regulatory oversight (who watches it), and business model (how it makes money). Understanding these categories helps you compare what each type offers and what trade-offs come with each choice.

Key Takeaways

  • Commercial banks are for-profit institutions owned by shareholders, offer the widest range of services, and are insured by the FDIC up to $250,000 per account type.
  • Credit unions are member-owned cooperatives that typically offer lower fees and better rates on savings and loans, but have smaller branch networks and fewer services.
  • Online banks have no physical branches, lower overhead costs, and often pay higher interest on savings accounts, but offer limited in-person support.
  • Savings banks and thrift institutions focus on savings accounts and mortgages rather than business lending, and are also FDIC-insured.
  • Community banks are smaller, locally-focused commercial banks that may offer more personalized service but typically have fewer branches and higher fees than national banks.

Commercial banks: the largest and most common option

A commercial bank is a for-profit institution owned by shareholders. It accepts deposits, makes loans to individuals and businesses, and offers a full range of financial services — checking and savings accounts, credit cards, mortgages, auto loans, investment products, and business banking. Wells Fargo, Bank of America, Chase, and Citibank are examples. These banks are regulated by the Office of the Comptroller of the Currency (OCC), the Federal Reserve, or the FDIC, depending on their charter type.

Deposits at commercial banks are insured by the FDIC up to $250,000 per depositor, per account type, per bank. This means if the bank fails, you get your money back up to that limit. Commercial banks make money by charging fees on accounts and services, and by lending out deposits at higher interest rates than they pay on savings accounts.

The trade-off: commercial banks have extensive branch and ATM networks, which is convenient if you need in-person service. But they typically charge monthly maintenance fees, require minimum balances, and pay lower interest on savings accounts than online banks or credit unions do.

Credit unions: member-owned and often cheaper

A credit union is a nonprofit, member-owned cooperative. You must be a member to open an account, and membership is usually based on where you work, where you live, or an organization you belong to. Examples include Navy Federal Credit Union, Alliant Credit Union, and local credit unions tied to employers or communities. Credit unions are regulated by the National Credit Union Administration (NCUA), which also insures deposits up to $250,000 per member, per account type.

Because credit unions are nonprofits, they return profits to members in the form of lower fees and higher interest rates on savings. They typically charge no monthly maintenance fee, have no minimum balance requirements, and pay more on savings accounts than commercial banks. However, credit unions have smaller branch and ATM networks, which can be inconvenient if you travel or need frequent in-person access.

Credit unions also tend to be more flexible with lending — they may approve a loan or credit card when a commercial bank would decline. The catch is that not all credit unions offer the same services; some have limited online banking, and some don't offer credit cards or investment products.

Online banks: higher rates, no branches

An online bank operates entirely through the internet and has no physical branches. Examples include Ally Bank, Marcus by Goldman Sachs, Discover Bank, and Charles Schwab Bank. Online banks are chartered and regulated the same way as commercial banks — by the OCC, Federal Reserve, or FDIC — and deposits are FDIC-insured up to $250,000 per account type.

Online banks have much lower overhead costs than brick-and-mortar banks because they don't maintain branch networks. They pass those savings to customers in the form of higher interest rates on savings accounts and money market accounts, and lower or no monthly fees. Many online banks also reimburse ATM fees nationwide, which offsets the lack of their own ATM network.

The main drawback is that you cannot walk into a branch to deposit cash, withdraw large amounts, or speak to someone in person. Most online banks accept mobile check deposit and transfers, but if you need to deposit cash frequently or prefer face-to-face service, an online bank may not fit your needs.

Savings banks and thrift institutions: focused on mortgages and savings

A savings bank (also called a thrift institution or savings and loan) is a financial institution chartered to focus on savings accounts and mortgages rather than general business lending. They are regulated by the OCC or the FDIC and are FDIC-insured. Many savings banks have converted to commercial bank charters or been acquired by larger banks, but some still operate independently.

Savings banks typically offer competitive rates on savings accounts and specialize in home loans. They may have lower fees than commercial banks and a more personal approach to mortgage lending. However, they usually have smaller branch networks and offer fewer services — you may not find credit cards, investment products, or business accounts.

Community banks: local, smaller, and more selective

A community bank is a smaller commercial bank, usually with fewer than 10 branches, that serves a specific geographic area or community. They are regulated and FDIC-insured like other commercial banks. Examples include local or regional banks you might find in your town or city.

Community banks often offer more personalized service and may be more willing to work with local businesses and borrowers with complex financial situations. However, they typically charge higher monthly fees than national banks, have limited online banking platforms, and offer fewer services overall. They also have smaller ATM networks, which can be inconvenient if you travel.

How to choose which type fits your needs

The right bank depends on how you use money. If you need frequent in-person service, a large branch network, and a full range of products, a national commercial bank or community bank may be best. If you want the lowest fees and highest savings rates and don't mind doing everything online, an online bank is usually the better choice. If you value lower fees, better rates, and a nonprofit structure, a credit union is worth exploring — but check whether you're may be able to access to join.

You can also use more than one bank. Many people keep a checking account at a commercial bank for convenience and a high-yield savings account at an online bank to earn more interest. The key is understanding what each type offers and what trade-offs come with each choice.

Frequently Asked Questions

Can I join a credit union if I don't work for the employer it's tied to?

It depends on the credit union's membership rules. Some credit unions are open to anyone in a geographic area; others are restricted to employees of a specific company, members of a union, or people who live in a certain county. Check the credit union's website or call to see if you're may be able to access.

Do online banks have ATMs?

Most online banks don't own ATMs, but many reimburse ATM fees charged by other banks nationwide. Some partner with ATM networks like Allpoint or MoneyPass to offer surcharge-free withdrawals at thousands of locations. Check your bank's policy before opening an account if ATM access matters to you.

What's the difference between a savings bank and a commercial bank?
