What to look for before you open a credit union checking account

The lowest-fee checking account is not always the one with zero monthly fees. A credit union might charge nothing per month but hit you with a $3 overdraft fee every time you go negative, or charge $1 per debit card transaction after ten per month. Another might have a $5 monthly fee but unlimited transactions and no overdraft charges if you link a savings account. You need to know which fees actually apply to how you spend money.

Start by listing the things you do with a checking account: How many debit card swipes per month? Do you write checks? Do you use ATMs outside the credit union network? Do you ever go negative? Do you keep a minimum balance easily, or does your balance fluctuate? The account that costs you the least is the one whose fee structure matches your actual behavior, not the one with the lowest advertised fee.

Most credit unions publish their fee schedules online as a PDF or in their account terms. Download it before you visit a branch. The fee schedule is the only document that tells you what you will actually pay.

Key Takeaways

  • Monthly maintenance fees, overdraft fees, and per-transaction charges vary widely between credit unions, so compare the full fee schedule, not just the headline rate.
  • The cheapest account for you depends on your behavior: how many debit transactions you make, whether you use out-of-network ATMs, and whether you maintain a minimum balance.
  • Many credit unions waive monthly fees if you set up direct deposit or keep a minimum balance, so ask whether those waivers apply to the account you want.
  • Overdraft protection linked to a savings account or another account can prevent overdraft fees, but you pay a transfer fee each time the link is used.
  • Credit union ATM networks (like CO-OP or Allpoint) can save you money if you use ATMs frequently, so check which network your credit union belongs to.

Monthly maintenance fees and how to waive them

Most credit unions charge a monthly maintenance fee between $0 and $10, but many waive it if you meet one condition. Common waivers include: direct deposit of any amount, maintaining a minimum balance (often $500 to $1,000), or keeping a linked savings account open. Some credit unions waive the fee only if you meet one condition; others waive it if you meet any one of several. Read the account terms carefully, because the difference between "direct deposit of $500 or more per month" and "any direct deposit" can mean $60 per year.

If you do not receive direct deposit and cannot maintain a high balance, ask whether the credit union offers a checking account with no monthly fee at all. Many do, though they may charge higher per-transaction fees or have lower ATM network access to offset the lower headline cost.

Debit card and transaction fees

Some credit unions charge per debit card transaction after a certain number per month—often $0.25 to $0.50 per swipe after ten or twenty transactions. If you use your debit card fifty times per month, this adds up fast. Other credit unions charge nothing per transaction but have a higher monthly fee. A third group charges nothing for either.

Check whether the credit union counts online bill pay as a transaction. Some do; some do not. If you pay five bills online per month and the credit union counts each one, that could be five charges per month if you exceed the free limit. Ask the credit union directly: "Does online bill pay count toward my transaction limit?"

ATM withdrawals sometimes count as transactions, and sometimes they do not. This matters if you use ATMs frequently. The fee schedule should say, but if it is unclear, call the credit union and ask.

Overdraft fees and overdraft protection

An overdraft fee is charged when your account goes negative and the credit union covers the transaction anyway. Fees range from $25 to $40 per overdraft, and some credit unions charge multiple fees per day if you stay negative. This is one of the most expensive fees in banking.

The cheapest way to avoid overdraft fees is to link your checking account to a savings account at the same credit union and set up overdraft protection. When you go negative, the credit union automatically transfers money from savings to checking to cover it. You pay a transfer fee—usually $1 to $3 per transfer—but that is far less than an overdraft fee. The transfer also prevents the overdraft from being reported to ChexSystems, which can affect your ability to open accounts elsewhere.

Some credit unions offer overdraft protection linked to a line of credit instead of a savings account. This works the same way but may have a higher transfer fee or interest charge. Ask which option is available and what each costs.

If you do not want overdraft protection, ask whether the credit union offers opt-out overdraft. This means transactions are simply declined if you do not have the money, rather than being covered and charged a fee. Not all credit unions offer this, but many do.

ATM fees and network access

Credit unions belong to ATM networks that let you withdraw cash at other credit unions' ATMs without a fee. The two largest networks are CO-OP and Allpoint. CO-OP has roughly 30,000 ATMs; Allpoint has roughly 55,000. If your credit union belongs to one of these networks, you can use thousands of ATMs for free.

If your credit union does not belong to a large network, or if you use ATMs outside the network, you will pay an out-of-network fee—usually $2 to $3 per withdrawal. Some credit unions reimburse a certain number of out-of-network fees per month (often one or two), but most do not. If you use ATMs frequently and your credit union has limited network access, this fee can cost you $30 to $50 per month.

Before you open an account, ask which network the credit union belongs to and whether you can access ATMs near your home and work for free. If the credit union has no network or a small one, factor out-of-network fees into your total cost.

Minimum balance requirements and balance-based fees

Some credit unions require you to maintain a minimum balance—often $500 to $1,000—to avoid a monthly fee or to earn interest on the account. If your balance falls below the minimum, you pay a fee, usually $5 to $10 per month. This is different from a monthly maintenance fee; it only applies if you go below the threshold.

If you cannot reliably maintain a minimum balance, choose an account with no minimum or a very low one ($100 or less). The fee for falling below a high minimum will cost more than the monthly fee on an account with no minimum.

Some credit unions also charge a low balance fee if your account stays below a certain amount for a certain number of days. This is rare, but it exists. Read the fee schedule carefully.

Comparing accounts side by side

Create a simple spreadsheet with the accounts you are considering across the top and the fees down the left side. Fill in each fee for each account. Then estimate your monthly usage: How many debit transactions? How many out-of-network ATM withdrawals? How often do you go negative? Multiply each fee by your estimated usage and add them up. The account with the lowest total is the one that costs you the least.

Example: Credit Union A charges $5 per month, no transaction fees, and $35 per overdraft. Credit Union B charges $0 per month, $0.50 per transaction over ten per month, and $25 per overdraft. If you make thirty debit transactions per month and go negative once per month, Credit Union A costs $5 + $35 = $40. Credit Union B costs $0 + (20 × $0.50) + $25 = $35. Credit Union B is cheaper for your behavior, even though it has no monthly fee.

Questions to ask before you sign up

Call or visit the credit union and ask these questions in writing or by email so you have a record of the answers:

  1. What is the monthly maintenance fee, and what waivers apply?
  2. Are there per-transaction fees, and if so, how many free transactions do I get per month?
  3. Do online bill pay and ATM withdrawals count as transactions?
  4. What is the overdraft fee, and can I set up overdraft protection linked to a savings account?
  5. What ATM network does the credit union belong to, and how many ATMs are in that network?
  6. What is the out-of-network ATM fee?
  7. Is there a minimum balance requirement, and what happens if I fall below it?
  8. Do you offer opt-out overdraft so transactions are declined instead of covered?

Frequently Asked Questions

Can I switch to a different account at the same credit union if I find a better fit?

Yes. Most credit unions let you change account types without closing and reopening, which means you keep the same account number and routing number. Ask whether switching accounts counts as a new account opening (which might trigger a hard inquiry on your credit report). Usually it does not.

What if the credit union charges a fee I did not expect?

Ask the credit union to reverse it, especially if it is your first time. Many credit unions will waive one unexpected fee as a courtesy. If the fee was charged because you did not understand the terms, the credit union may reverse it and explain the fee structure more clearly. If the fee was charged correctly according to the terms you agreed to, the credit union is not required to reverse it, but asking costs nothing.

Do credit unions report checking account activity to credit bureaus?

No. Checking accounts do not appear on your credit report. Only credit products (credit cards, loans, lines of credit) are reported. Opening a checking account does not affect your credit score.

Is it worth opening a savings account at the same credit union to get overdraft protection?

Only if overdraft protection saves you more than the cost of maintaining the savings account. If the savings account has no monthly fee and you keep even $50 in it, the overdraft protection is free. If the savings account charges a monthly fee, calculate whether you will overdraft often enough to make the protection worth it. If you overdraft once per year, paying $35 per overdraft is cheaper than paying a monthly fee.

What happens if I close my checking account but still have overdraft protection set up?

The overdraft protection link is usually canceled when you close the account. Make sure your savings account is not also closed, or you will lose access to any money in it. Close accounts in writing or in person, not by phone, so you have proof of the closure date.
