The difference comes down to who owns the institution — and who it's trying to profit
A bank is a for-profit corporation owned by shareholders. When a bank earns money — from interest on loans, from fees, from investing your deposits — those profits flow to shareholders first. Customers are the revenue source, not the beneficiaries. That's not a criticism; it's simply how the structure works. Banks compete for your business, and competition does constrain their behavior, but their fundamental obligation is to their owners.
A credit union is a not-for-profit financial cooperative owned by its members — meaning you, when you open an account. There are no outside shareholders. Any money left over after operating costs is returned to members in the form of better rates on savings accounts, lower rates on loans, and reduced fees. The National Credit Union Administration (NCUA) regulates federal credit unions the same way the FDIC oversees banks, and deposit insurance works identically — up to $250,000 per depositor.
In practice, this structural difference shows up most clearly in three places: monthly maintenance fees (credit unions charge them far less often), interest rates on savings and loans (credit unions typically edge out banks), and customer service (credit unions score higher on member satisfaction surveys, though larger banks have invested heavily in technology to close that gap). Where banks tend to win: ATM network size, digital product sophistication, and the sheer range of financial products on offer.
People ask this question for very different reasons — which one fits you?
The underlying question is the same, but what you're really trying to decide usually depends on where you are right now. Pick the situation that matches yours.
Staying with the wrong institution is a quiet, ongoing cost — not a one-time mistake
Most people don't make a deliberate choice between banks and credit unions — they just end up somewhere by default, usually the institution their parents used or the one closest to their first apartment. That's fine, but it means many people are paying fees they don't need to pay, or earning interest rates well below what's available to them. The difference isn't catastrophic, but over years it compounds into real money.
If you're carrying a car loan, a personal loan, or a home equity line, the rate difference between a credit union and a large commercial bank can easily run 0.5 to 1.5 percentage points. On a $20,000 car loan over five years, that's several hundred dollars in interest. On the savings side, the gap between a major bank's standard savings rate and a credit union's dividend rate can be even wider — particularly since large banks have been slow to pass on rate increases to depositors.
According to NCUA data, credit unions consistently offer lower average rates on new car loans and higher average rates on savings accounts than banks of comparable size. In 2025, the national average credit union new car loan rate was approximately 0.8 percentage points lower than the equivalent bank rate — a gap that adds up to hundreds of dollars over a standard loan term.

I switched to a local credit union two years ago after my bank started charging a $15 monthly maintenance fee unless I kept a $1,500 minimum balance. The credit union has no minimum, no monthly fee, and my savings rate went from basically zero to over 4%. I do miss the bank's app — it was smoother — but I've saved probably $400 in fees alone.

I keep both, honestly. My credit union is where I keep my savings and where I got my car loan — the rate was a full point lower than what Chase quoted me. But I keep a checking account at a big bank because the ATM network is massive and I travel for work. Using them for different things has worked really well for me.

I tried to join a credit union and found the eligibility rules confusing at first — I thought I had to work for a specific employer. Turns out my local community credit union was open to anyone who lives in the county. Worth checking carefully because the field of membership rules have loosened up a lot in recent years. Ended up joining and haven't regretted it.
