Credit unions and banks both hold your paycheck, issue debit cards and make car loans. The difference that matters is who they work for, and it shows up in the rates.

Who owns it

A bank is owned by shareholders, and its profits go to them. A credit union is a not-for-profit cooperative owned by its members, which means you, with one vote per member no matter how much money you keep there. Earnings come back to members as lower loan rates, higher savings rates or lower fees, or are held as capital.

Is your money as safe?

Deposit insurance is the same size. Banks are covered by the FDIC and federally insured credit unions by the NCUA, each up to $250,000 per depositor, per institution, per ownership category, as NCUA explains in its Your Insured Funds guide. So a credit union is not riskier or safer than a bank on insurance alone. Not every credit union is federally insured, though, so confirm yours in NCUA's locator before you deposit.

Where the money difference shows up

The NCUA publishes national average rates for both, built from S&P Global Market Intelligence data. In its comparison for December 26, 2025, the latest I could find, credit unions came out ahead on borrowing and on CDs.

Borrowing: new-car loans (60 months) averaged 5.44% at credit unions versus 7.41% at banks. Classic credit cards averaged 12.58% versus 15.27%, and 36-month unsecured loans 10.64% versus 12.00%. Thirty-year mortgages were much closer, 6.26% versus 6.50%.

Saving: one-year CDs paid 2.95% versus 2.29%, and five-year CDs 2.83% versus 2.11%. Money market accounts averaged 0.74% versus 0.52%.

Banks won on everyday accounts. Regular savings averaged 0.32% at banks versus 0.19% at credit unions, and interest checking 0.20% versus 0.15%. The gaps are small, but they undercut the idea that credit unions always pay more.

What does the loan gap mean in dollars? On a $30,000 five-year car loan, 5.44% works out to about $572 a month and 7.41% to about $600. That is roughly $28 a month, or about $1,660 over the life of the loan. (That is my arithmetic from the NCUA averages. Your actual rate depends on your credit and the lender.)

Who can join

Banks accept nearly anyone. A credit union has a "field of membership," a common bond such as an employer, an association or a local community. NCUA's chartering guide says immediate family and household members of a member can usually join too. Many credit unions define their community broadly, so it is often easier than people expect.

When a bank may fit better

Credit unions can have fewer branches and a narrower product menu, so check ATM access, the mobile app and any business-account needs before you switch. App-only banks are a third option, and we looked at what to weigh in our report on digital banks.

Why it matters

Credit unions are one of the oldest alternatives to big-bank finance, and they are not small. Federally insured credit unions held $2.50 trillion in assets as of June 2026, up 5.0% in a year, NCUA reported. Since deposit insurance is equal, the choice comes down to price, convenience and ownership model. Our look at credit union growth covers the latest membership numbers.

What you can do

Use NCUA's credit union locator to see which ones you could join and to confirm federal insurance, and check any bank in the FDIC's BankFind tool. Then compare the actual rate sheets and fee schedules for the products you use, such as an auto loan, card, savings and checking. Rates vary a lot within each category, so the average is a starting point, not a verdict.
