Credit unions are a different kind of financial institution. They are member-owned, not-for-profit organizations that often offer better rates, lower fees, and friendlier service than big banks. This guide explains how credit unions work, how they compare to banks, and whether you should switch.
What Is a Credit Union?
A credit union is a member-owned financial cooperative. When you join a credit union and open an account, you become a member and part-owner. Credit unions are not-for-profit, so any earnings go back to members in the form of lower fees, higher savings rates, and lower loan rates.
Banks, by contrast, are for-profit businesses owned by shareholders. Their goal is to maximize profit, which sometimes comes at the expense of customer fees and rates.
How Credit Unions Are Different from Banks
| Feature | Credit Union | Bank |
|---|---|---|
| Ownership | Members (you) | Shareholders (investors) |
| Profit purpose | Returned to members | Paid to shareholders |
| Deposit insurance | NCUA (up to $250K) | FDIC (up to $250K) |
| Loan rates | Usually lower | Vary widely |
| Savings rates | Usually higher | Vary widely |
| Fees | Usually lower | Often higher |
| Branch network | Usually smaller | Often larger |
| Technology/apps | Can lag behind | Usually better |
Are Credit Unions Safe?
Yes. Credit union deposits are insured by the National Credit Union Administration (NCUA), a federal agency. The NCUA insures accounts up to $250,000 per member, per ownership category — the same protection level as FDIC insurance at banks. Your money is equally safe at a federally insured credit union as at any bank.
Benefits of Credit Unions
Lower Loan Rates
Credit unions tend to offer lower rates on car loans, personal loans, mortgages, and credit cards. On a $25,000 car loan, even a 1% rate difference saves you hundreds of dollars over the loan term.
Higher Savings Rates
Credit unions often pay higher rates on savings accounts and CDs than big banks. Not always higher than top online banks, but usually better than traditional brick-and-mortar banks.
Lower Fees
Credit unions typically charge lower or no monthly fees on checking and savings accounts. Overdraft fees are also often lower.
Personalized Service
Credit unions are community-focused. Members often report better customer service and more flexibility when they need help (like working through a financial hardship).
Downsides of Credit Unions
Membership Requirements
You must qualify to join a credit union. Membership is usually tied to your employer, geographic area, military service, profession, or affiliation with a specific group. However, many credit unions have broadened their membership criteria. Some allow anyone to join by making a small donation to a partner organization.
Fewer Branches and ATMs
Most credit unions are smaller than national banks. They may have fewer branches and ATMs. However, many credit unions belong to shared branching networks and surcharge-free ATM networks like CO-OP, which gives members access to thousands of locations.
Technology Can Be Behind
Some credit unions have less polished mobile apps and online banking tools than major banks like Chase or Bank of America. This gap has narrowed, but it still exists at smaller institutions.

Should You Switch to a Credit Union?
Consider a credit union if you want lower loan rates, are frustrated by bank fees, or value personalized service. Keep your bank if you need a large ATM network, prefer a polished mobile app, or use features like Zelle that require a major bank.
Many people use both: a credit union for loans and savings, and a big bank or online bank for everyday checking. See our guide to Best Checking Accounts 2026 for top online alternatives.
