Credit union vs. bank: What to consider when choosing

Choosing between a bank and a credit union may involve some tradeoffs on interest rates, technology and tools, and ATMs and branches.

• Interest rates: On average, credit unions tend to offer higher rates on deposits and lower rates on loans. (Check out average bank interest rates for savings accounts, CDs and more.)

• Technology and tools: Banks often adopt new technology and tools more quickly, especially online banks, which are typically able to offer higher-than-average interest rates. 

• ATMs and branches: Broad ATM and branch networks are the norm for national banks; credit unions might belong to large, cooperative networks of ATMs, such as Allpoint, and offer shared branches. If in-person service matters to you, look at banks and credit unions that have local branches. If you just need to withdraw or deposit cash on a regular basis, verify you’ll have enough fee-free ATMs nearby.

Banks are for-profit enterprises, while credit unions are not-for-profit.

• Credit unions in principle exist to serve a community of people tied by a “bond of association,” which may be based on location, employer, faith, membership in another organization or other factors. 

• To serve its community, a credit union provides financial products on the most favorable terms it can afford to offer. 

Some banks and credit unions charge fees.

• Ask about monthly maintenance and overdraft fees. Many banks and credit unions offer ways for customers to waive a monthly fee, such as having at least one monthly direct deposit or maintaining a minimum balance. 

• While many financial institutions have eliminated or cut back on charging for overdrawn accounts, for the banks and credit unions that still charge for them, overdraft fees can get quite expensive, often in the range of $30-35, and can sometimes be charged multiple times per day.

Making your choice between a credit union and a bank

• Identify what features matter to you most. Figure out which account and customer service features work best for your situation, and make a prioritized list.

• Find your top contenders. Research which national, local and/or online banks and credit unions offer the best account features for what you need. Consider NerdWallet’s recommended credit unions and national banks.

• Narrow the list based on your top criteria. Other aspects to consider: Do some contenders on your list perform better in ways you might value in the future (such as having a great digital experience, extensive ATM access or loan offerings)? Do any negatives (higher fees, too few branches) change your mind about which to choose? 

Once you’ve found a bank or credit union that suits your needs, apply for an account.
