Key takeaways
- Credit unions are nonprofit cooperatives owned by their members; banks are for-profit companies owned by shareholders. There were 4,214 federally insured credit unions with 146.1 million members as of June 30, 2026 (NCUA).
- Both are insured up to $250,000 per depositor, per institution, per ownership category: credit unions by the NCUA, banks by the FDIC.
- Credit unions averaged 5.44% on 60-month new car loans versus 7.41% at banks in NCUA’s latest comparison (December 2025). On a $30,000 loan, that gap is worth about $1,659 in interest.
- Federal credit unions can’t charge more than 18% APR on most loans; the NCUA extended that ceiling through Sept. 10, 2027.
Credit unions usually offer lower loan rates and fees, while banks, especially large and online ones, usually offer more branches, better technology and higher savings yields. The right choice depends on whether you mainly borrow, save or need wide access.
Credit unions and banks offer many of the same products: checking and savings accounts, CDs, credit cards, auto loans, personal loans and mortgages. The big difference is ownership. A credit union returns its earnings to members through better rates and lower fees, while a bank aims to earn a profit for shareholders. Here’s how they compare in 2026, with real rate data and a worked example.
Credit unions vs. banks: side by side
| Feature | Credit unions | Banks |
|---|---|---|
| Ownership | Members (nonprofit cooperative) | Shareholders (for-profit) |
| Deposit insurance | NCUA, up to $250,000 | FDIC, up to $250,000 |
| Who can join | People who meet membership rules | Anyone |
| Loan rates | Often lower; federal credit unions capped at 18% on most loans | Vary widely by bank and credit |
| Fees | Often lower | Varies; large banks often charge more |
| Branches and ATMs | Fewer, but many share networks (CO-OP shared branches and ATMs) | Large national networks |
| Technology | Varies; some lag behind | Often more advanced apps |
| Taxes | Generally exempt from federal income tax | Pay corporate income tax |
How rates compare
The NCUA publishes average rates at credit unions and banks each quarter. Its most recent comparison, as of Dec. 26, 2025, shows credit unions ahead on most loans and on CDs, while banks paid slightly more on regular savings.
| Product | Credit unions | Banks |
|---|---|---|
| 60-month new car loan | 5.44% | 7.41% |
| 48-month used car loan | 5.53% | 7.73% |
| 36-month unsecured personal loan | 10.64% | 12.00% |
| Classic credit card | 12.58% | 15.27% |
| 30-year fixed mortgage | 6.26% | 6.50% |
| 1-year CD ($10,000) | 2.95% | 2.29% |
| Regular savings ($2,500) | 0.19% | 0.32% |
| Money market ($2,500) | 0.74% | 0.52% |
These are averages. The best online banks pay far more on savings, up to about 4.20% APY in early November 2026, with most big online banks at 3.20%–3.75%, so a credit union isn’t automatically the best place to save. Compare in our high-yield savings guide.

What the difference is worth: a worked example
Say you finance a $30,000 car over 60 months.
| Lender | APR | Monthly payment | Total interest |
|---|---|---|---|
| Credit union average | 5.44% | $572.20 | $4,332.26 |
| Bank average | 7.41% | $599.86 | $5,991.37 |
The credit union rate saves about $27.66 a month and $1,659.11 over the loan. On a $10,000, 36-month personal loan, the average rates (10.64% vs. 12.00%) work out to payments of $325.68 vs. $332.14, a savings of about $232 in interest. Check your own numbers with our auto loan calculator or loan comparison calculator, and see our guide to auto loan rates.
Tip: Get preapproved by a credit union before you visit a car dealer. A written offer gives you a rate to beat, and dealers will often match it.
Who can join a credit union?
Every credit union has a “field of membership.” Common ways to qualify include:
- Living, working, worshiping or going to school in a certain area.
- Working for a specific employer or in a certain industry.
- Military service or a family member’s service (for example, Navy Federal Credit Union).
- Joining a partner association, sometimes for a small one-time donation.
Many credit unions also accept family or household members of existing members. You’ll usually open a savings “share” account with a small deposit, often $5 to $25, to become a member.
How to join a credit union
- Search for eligible credit unions. Start with your employer’s benefits page, your school’s alumni association and the NCUA’s online credit union locator.
- Read the membership rules on the credit union’s website. Some list a partner charity or association you can join to qualify.
- Apply online or in a branch with a government ID, your Social Security number and proof of address.
- Fund your share account with the minimum deposit. That makes you a member-owner with a vote in board elections.
- Apply for the product you came for, such as a car loan or credit card. Some credit unions let you join and apply for a loan at the same time.
Membership is usually for life. If you change jobs or move away, most credit unions let you keep your accounts as long as they stay in good standing.
Pros of credit unions
- Lower loan rates on auto loans, personal loans and credit cards. See current averages in our personal loan guide.
- Lower or fewer fees, including lower overdraft fees at many institutions.
- Member-focused service and more flexibility for borrowers with thin credit.
- Small-dollar loans. Federal credit unions can offer payday alternative loans (PALs) with APRs capped at 28% and application fees of no more than $20, far cheaper than payday loans.
Cons of credit unions
- Membership requirements can limit who joins.
- Fewer branches, although shared branching and CO-OP ATMs help.
- Apps and online tools can be less polished than large banks’.
- Savings rates at many credit unions trail the top online banks.
When a bank may be the better choice
- You travel often and want branches and ATMs nationwide.
- You want the highest savings yields, which are often at online banks.
- You need specialized services such as business banking, wealth management or frequent international wires.
You don’t have to pick just one. Many people borrow from a credit union for lower loan rates while keeping savings at a high-yield online bank. Shopping for a mortgage? Get a quote from at least one credit union; see our mortgage guide.
How to choose, step by step
- List what matters most: loan rates, savings yield, branches or technology.
- Check eligibility for credit unions near you or tied to your employer, school or family.
- Compare fee schedules, especially overdraft and monthly maintenance fees.
- Confirm insurance with the NCUA’s credit union locator or the FDIC’s BankFind.
- Test the app and customer service before moving your direct deposit. Our guide on how to switch banks explains the steps.
Frequently asked questions
Is my money safer at a bank or a credit union?
Both are equally safe up to the insurance limit. The NCUA insures credit union deposits and the FDIC insures bank deposits, and both are backed by the full faith and credit of the U.S. government.
Do credit unions check credit?
Yes, for loans and credit cards. Some may also check your banking history when you open a checking account.
Can I use a credit union while traveling?
Many credit unions belong to shared branch and CO-OP ATM networks, giving members access to thousands of locations nationwide.
Are credit union auto loans cheaper?
On average, yes. NCUA data showed a roughly 2-point gap on new car loans at the end of 2025. Still, compare offers from banks and the dealer before you buy.
Can I belong to more than one credit union?
Yes, as long as you meet each one’s membership rules. Your NCUA coverage applies separately at each credit union.
