The main choice is between a traditional bank branch, a credit union, or an online bank — each has different costs, convenience, and support
Where you open a checking account depends on what matters most to you: low fees, in-person service, high interest on your balance, or convenience. A traditional bank with physical branches gives you a teller to talk to and an ATM network. A credit union typically charges fewer fees and offers better rates, but membership is limited to certain groups. An online bank has the lowest fees and often pays interest on checking balances, but you handle everything by phone, app, or website — there is no branch to walk into.
The account itself works the same way regardless of where you open it: you deposit money, write checks or use a debit card, and the bank holds your funds and processes your transactions. The differences are in what you pay, what you earn, and how you interact with the institution.
Key Takeaways
- Traditional banks offer branch locations and teller service but often charge monthly fees unless you maintain a minimum balance or set up direct deposit.
- Credit unions typically have lower fees and better interest rates on checking accounts, but you must be a member of an employer, union, or community group to join.
- Online banks have no monthly fees and often pay interest on checking balances, but all transactions happen through an app or website with no physical location.
- Compare the monthly fee, minimum balance requirement, ATM access, and interest rate before opening, because these costs add up over time.
Traditional banks: branch access and established networks
A traditional bank is a for-profit company with physical locations in your area. You can walk in to deposit cash, speak with a banker about loans, or ask questions about your account. Most traditional banks charge a monthly maintenance fee — typically $10 to $15 — unless you meet certain conditions like keeping a minimum balance (often $500 to $1,500), setting up direct deposit, or maintaining a certain number of debit card transactions per month.
The advantage is convenience and human contact. If you need to deposit a check, withdraw cash, or discuss a problem, you have a person to talk to. Most traditional banks also belong to large ATM networks, so you can withdraw cash without a fee at thousands of locations nationwide.
The disadvantage is cost. If you cannot meet the fee waiver conditions, you will pay $120 to $180 per year just to keep the account open. Traditional banks also rarely pay interest on checking balances — your money sits there earning nothing.
Credit unions: lower fees and better rates for members
A credit union is a nonprofit organization owned by its members. It operates similarly to a bank — you deposit money, write checks, use a debit card — but it is run to benefit members rather than shareholders. Credit unions typically charge no monthly fee or a very low one ($3 to $5), and many pay interest on checking balances, even if the rate is modest.
The catch is membership. You cannot simply open an account at any credit union. You must belong to a specific group: employees of a particular company, members of a union, residents of a certain county, students at a particular school, or members of a professional or religious organization. Some credit unions have broader membership rules — for example, anyone who lives or works in a certain area — but you still have to meet the requirement.
To find a credit union you can join, search the CO-OP network or Alliant Credit Union's directory online, or ask your employer or union whether they sponsor one. Once you join, you gain access to a network of shared branches and ATMs across the country, so you can conduct business at other credit unions' locations even if you do not have a local branch.
Online banks: lowest fees and interest, no branches
An online bank exists only as a website and mobile app. You have no physical location to visit, no teller to speak with in person, and no local branch. Everything happens through your phone or computer: you deposit checks by photographing them with your app, transfer money between accounts, pay bills, and contact customer service by chat or phone.
Online banks have the lowest fees because they have no branch overhead. Most charge no monthly maintenance fee at all. Many also pay interest on checking balances — sometimes 4% to 5% annually, depending on the bank and current rates — which means your money earns money while it sits there.
The trade-off is lack of in-person service. If you need to deposit cash, you cannot walk into a branch; you will need to find a partner bank or ATM network that accepts deposits. If you have a problem, you cannot sit down with someone face-to-face. For most people this is fine, but if you prefer human interaction or handle a lot of cash, an online bank may not suit you.
Comparing fees, minimums, and ATM access across account types
| Account Type | Typical Monthly Fee | Minimum Balance | Interest on Checking | ATM Access |
|---|---|---|---|---|
| Traditional Bank | $10–$15 (waived with conditions) | $500–$1,500 | Rarely | Large nationwide network |
| Credit Union | $0–$5 | Usually $0–$100 | Often yes, modest rate | CO-OP and Alliant networks |
| Online Bank | $0 | Usually $0 | Often yes, competitive rate | Partner ATM network or check deposit only |
The monthly fee is the most visible cost, but minimum balance requirements matter too. If a bank requires you to keep $1,000 in the account at all times and you cannot do that, you will pay a fee every month. An online bank with no minimum and no fee is cheaper than a traditional bank with a $15 monthly fee, even if the traditional bank has better ATM access.
Interest on checking is rare at traditional banks but common at credit unions and online banks. If you keep $5,000 in your account and earn 4% interest annually, that is $200 per year. Over time, this adds up.
What to check before you open an account
Before opening an account anywhere, verify three things: the monthly fee and how to waive it, the ATM network and whether you can access it near your home or work, and the interest rate on checking balances if you have money to keep there.
Ask whether the bank or credit union offers mobile check deposit, because this matters if you receive paper checks. Ask about overdraft fees — what happens if you spend more than you have — and whether the institution offers overdraft protection (a link to savings or a credit line that covers the shortfall). Ask whether there are fees for wire transfers, stop payments, or other services you might need.
If you are considering a traditional bank, ask exactly what conditions waive the monthly fee. "Direct deposit" sounds simple, but some banks require a minimum deposit amount per month, and some require the deposit to come from an employer or government agency — a transfer from your own savings account does not count.
Special cases: high-balance accounts and business checking
If you keep a large balance in your checking account — say, $25,000 or more — some traditional banks offer premium checking accounts with higher interest rates, better ATM access, and fee waivers. These accounts are worth comparing if you have substantial savings.
If you are opening a business checking account rather than a personal one, the landscape changes. Most online banks do not offer business accounts. Credit unions may or may not, depending on their membership rules. Traditional banks dominate business checking, though they charge higher fees — typically $20 to $30 per month — because business accounts involve more transactions and higher liability. Shop around, because some banks waive business checking fees if you maintain a certain balance or use their other services.
Frequently Asked Questions
Can I have checking accounts at more than one bank?
Yes. Many people keep accounts at two banks for convenience — perhaps a traditional bank for cash deposits and a credit union or online bank for lower fees. There is no limit to how many accounts you can open, though each bank will run a credit check and report the account to credit bureaus.
What if I do not have a minimum balance to meet?
An online bank or credit union is usually your best choice, because both typically have no minimum balance requirement and no monthly fee. If you prefer a traditional bank, look for one that waives the fee based on direct deposit or debit card use rather than balance.
Do I need a Social Security number to open a checking account?
Most banks require a Social Security number or Individual Taxpayer Identification Number (ITIN). Some banks and credit unions offer accounts to people without either, but options are limited. Call ahead to ask whether the institution you are considering will open an account for you.
How long does it take to open a checking account?
Online, it usually takes 5 to 10 minutes to complete the application. The bank then verifies your identity and may run a background check, which takes a few hours to a few days. You can usually start using the account within one business day, though some banks wait longer before allowing large transactions.
What happens to my money if the bank fails?
The Federal Deposit Insurance Corporation (FDIC) insures checking accounts at banks and the National Credit Union Administration (NCUA) insures accounts at credit unions. Both cover up to $250,000 per depositor per institution, so your money is protected even if the bank or credit union goes out of business.
