Banks and credit unions offer almost all the same things: checking and savings accounts, car loans, mortgages, credit cards, a mobile app. So what's actually different?
For any one product, the honest answer is that either one might have the best deal. But underneath the products, they're built differently: who owns them, who they answer to, and where the money they make ends up. On structure, one of them comes out ahead, and it's the credit union. Here's why, and where the exceptions are.
Banks: owned by investors
A bank is a business owned by investors. Some are publicly traded, with shares bought and sold on the stock market. Many more are privately held, owned by a family, a group of local investors, or a holding company. Either way, the owners elect the board of directors, and votes go by ownership: the more of the bank you own, the more say you have. When the bank makes money, part of it goes to those owners.
There's nothing wrong with that. It's how most companies work, Capitalism 101. Plenty of banks, especially small community banks, take their communities seriously. It does mean a bank has two groups to keep happy, and they don't want the same thing. Customers want the best rate, minimal fees, and the best features, while owners want to make money. Owners will give customers what they want, but their motivation is profit, so they will only go so far as the market pushes them to. There is one interesting exception. Mutual banks are owned by their depositors rather than by investors, which puts them closer to a credit union than to a big bank.
Some banks have no branches at all. Online banks do everything through an app and a website, and because they skip the cost of running branches, they often pay the highest rates on savings. They're still banks, owned by investors like any other.
Credit unions: owned by the people who bank there
A credit union is a not-for-profit cooperative. When you open an account you become a member, not a customer. That means you're an owner. Every member gets one vote for the board of directors, whether you have $50 in savings or $50,000. Unlike a bank, you are automatically on both sides of the customer/owner relationship. To be fair, most members never vote, and board elections tend to be quiet. But the structure matters even if you never use your vote.
Credit unions mostly make money in the same way that banks do: they lend out deposits at a higher rate than they pay on them. But they know that their members (customers) and their owners are the same people. That's why credit unions on average have lower rates on loans and pay higher rates on most deposits. That doesn't mean that you will always be approved for a loan or that you can't find a deposit account that pays more.
Credit union professionals speak of balancing the interests of the member and the membership. That's an acknowledgement that they may have to decline a loan or do something else that an individual member may not like, but they do so in defense of the larger group. The membership.
Credit union membership isn't guaranteed for everyone. You have to qualify to join, usually based on where you live or work or a group you belong to, though many credit unions are easy to join.
Credit unions also don't pay federal income tax. That's one of several reasons they can offer better rates. In our view, the ownership structure matters more.
The rates: better on average, not every time
This part can be checked. Every quarter, the NCUA, the federal agency that oversees credit unions, publishes average rates at banks and credit unions using data from S&P Global Market Intelligence. At the end of 2025, the latest figures published:
New car loan (60 months): 5.44% at credit unions, 7.41% at banks
Used car loan (48 months): 5.53% vs. 7.73%
Credit card: 12.58% vs. 15.27%
30-year fixed mortgage: 6.26% vs. 6.50%
1-year CD: 2.95% vs. 2.29%
Some of those gaps look small. About a quarter of a percentage point on a mortgage doesn't sound like much until you run it. On a $400,000, 30-year fixed mortgage, 6.26% instead of 6.50% saves about $63 a month. Keep the loan for the full 30 years and that's about $22,600. On a $44,000 new car loan, close to the national average, 5.44% instead of 7.41% saves about $40 a month, or about $2,400 by the time it's paid off.
Every loan type and every CD term in the comparison came out in credit unions' favor, and so did money market accounts. Two things didn't. Regular savings accounts averaged 0.32% at banks and 0.19% at credit unions, and interest checking was slightly higher at banks too. And if you want the highest rate on a savings account, online banks usually lead the pack.
An average is an average. It doesn't mean your local credit union beats the bank down the street on the product you need. It does mean credit unions are a good place to start looking.
Is your money safe?
Yes, at either one, up to a limit. Bank deposits are insured by the FDIC, a federal agency, up to $250,000 per depositor, per bank, for each ownership category (an individual account and a joint account count separately, for example). Credit union deposits are insured by the NCUA to the same $250,000, and both are backed by the full faith and credit of the United States. On safety, there's no difference between them.
If you have deposits above this amount, consider a strategy to distribute your deposits to maximize insurance.
So which one wins?
On structure, credit unions. You're an owner rather than a customer, you get a vote, and on average that shows up in the rates. That doesn't mean every credit union beats every bank on every product. It means you know what you're choosing.
Most people don't need to pick just one. A credit union for the car loan, an online bank for savings, and a big bank's credit card for the rewards is a perfectly reasonable setup.
