🎯 In 30 seconds: Each bank fee has a specific trigger, and nearly every trigger has a fix. You can refuse overdraft coverage on debit card and ATM transactions, link a savings account as a backup, turn on low-balance alerts, use in-network ATMs, and pick an account with no monthly fee. Credit unions are member-owned and often charge less, but you have to qualify to join.
The five fees and what sets them off
| Fee | What triggers it | How to avoid it |
|---|---|---|
| Overdraft | The bank pays a transaction your balance cannot cover. The FDIC says it may be around $35 each. | Decline debit and ATM overdraft coverage; link savings; set alerts. |
| NSF (non-sufficient funds) | The bank declines a check or electronic payment for lack of money | Keep a buffer; time bill due dates to land after payday. |
| Monthly maintenance | Not meeting the account’s conditions | Direct deposit, a minimum balance, or a no-fee account. |
| Minimum balance | Dropping below a set balance | Low-balance alerts, or an account without a minimum. |
| Out-of-network ATM | Using another bank’s ATM; you can be charged by both the ATM owner and your bank | In-network ATMs, cash back at stores, or a bank that reimburses ATM fees. |
Every bank must give you its fee schedule. Ask for it before you open an account, and look for these five lines first.
The opt-in choice that blocks most overdraft fees
Under federal rules, a bank cannot charge an overdraft fee on an ATM withdrawal or a one-time debit card purchase unless you opted in to overdraft coverage for those transactions. If you have not opted in, a purchase you cannot cover is usually just declined, with no fee.
Two limits to know:
- The opt-in rule does not cover checks and recurring automatic payments. The bank can still pay those into overdraft and charge a fee, or decline them and charge an NSF fee.
- You can change your mind. If you opted in at account opening without much thought, you can opt out at any time by telling your bank.
There is no federal cap on the size of overdraft fees. A 2024 CFPB rule that would have limited them at the largest banks was overturned by Congress in 2025.
Worked example: $70 in fees for $45 of purchases
Taylor has $20 in checking and is opted in to debit overdraft. The bank charges $35 per overdraft. In one afternoon Taylor buys:
| Lunch, $8 | Balance $12. No fee. |
| Gas, $15 | Balance −$3. Overdraft fee $35. |
| Groceries, $30 | Balance −$33. Overdraft fee $35. |
| Fees | $70 for $45 of overdrawn spending |
Not opted in, the gas and grocery purchases would have been declined at the register with no fee. That is awkward, but it costs nothing. Some banks also charge a daily fee for every day the account stays negative, so the cost can keep growing. (Banks differ: some have no overdraft fees at all, some allow a small cushion. Read yours.)
Other ways to cut fees
- Link a savings account to checking for overdraft protection. The FDIC notes the transfer fee, if any, is usually lower than an overdraft fee.
- Turn on alerts for low balance and for large transactions in your bank’s app.
- Count the ATM cost. Paying $3 to the ATM owner plus $2.50 to your own bank, twice a week, is $5.50 × 104 = $572 a year.
- Count the monthly fee. A $12 maintenance fee is $144 a year. One direct deposit a month often waives it; check your account’s terms.
- Ask for a refund. If a fee is rare for you, call and ask the bank to waive it. The FDIC suggests asking, and switching accounts or banks if the answer is no.
- Look for “Bank On” certified accounts. These low-cost accounts have no overdraft or NSF fees, and many banks and credit unions offer them.
Bank or credit union?
| Bank | Credit union | |
|---|---|---|
| Owned by | Shareholders; run for profit | Its members; not-for-profit, with a volunteer board elected by members |
| Who can join | Anyone | People in its “field of membership”: an employer, a place you live, work, worship or study, a group, or family of members |
| Deposit insurance | FDIC, up to $250,000 per depositor, per bank, per ownership category | NCUA, up to $250,000 per account ownership category at each insured credit union |
| Fees and rates | Varies widely; online banks often have no monthly fees | Earnings go back to members as lower fees and loan rates and higher savings rates |
| Branches and ATMs | Large banks have big networks | Often smaller, though many share networks with other credit unions |
| Small-dollar loans | Some offer them | Federal credit unions can offer payday alternative loans capped at 28% APR |
Many people use both: a credit union or online bank for checking, and a separate high-yield savings account for the emergency fund. Compare current savings yields in Rates, and see the basics of account types in the Bank accounts topic under Financial Education.

- What does it cost a year to pay $5.50 in ATM fees twice a week? Answer: $572.
- What decides whether you can join a credit union? Answer: Its field of membership, such as where you live or work.
