There is no federal limit on overdraft fees in dollar terms — banks set their own amounts, which still run as high as $35 per transaction at some institutions and average around $27 industrywide. Federal rules do control when a bank can charge you, and most large banks have added their own daily caps, small-balance buffers, and grace periods that function as practical ceilings on what you actually pay.
No Federal Cap on the Dollar Amount
Federal law does not specify a maximum amount a bank can charge for a single overdraft. Each institution sets its own fee, and the range is wide: as little as $10 at banks that have voluntarily reduced charges, and $35 or more at those that have not.
The Consumer Financial Protection Bureau finalized a rule in December 2024 that would have capped overdraft fees at $5 for banks and credit unions with more than $10 billion in assets, effective October 1, 2025. Congress repealed that rule under the Congressional Review Act in May 2025, and the CFPB is now barred from issuing a substantially similar regulation. No federal fee cap is in place or on the horizon.
Competitive pressure has done some of the work the rule would have. Capital One, Citibank, Ally Bank, and Discover have eliminated overdraft fees entirely. Bank of America, Huntington Bank, and KeyBank have cut fees to between $10 and $20 per occurrence. If your bank still charges $35, moving your checking account is often the fastest way to cap your exposure.
The Opt-In Rule Is the Strongest Actual Limit
The most meaningful federal restriction on overdraft fees is not a dollar cap but a consent requirement. Under Regulation E, a bank cannot charge you an overdraft fee for paying an ATM withdrawal or a one-time debit card purchase unless you have specifically agreed to that coverage in advance.1eCFR. 12 CFR 1005.17 – Requirements for Overdraft Services Without your opt-in, the bank must decline the transaction. No fee, no negative balance.
You can revoke your opt-in at any time, and the bank must process the revocation as soon as reasonably practicable.2Consumer Financial Protection Bureau. 12 CFR Part 1005 (Regulation E) – Section 1005.17 Requirements for Overdraft Services Call your bank, go online, or visit a branch and ask to opt out of overdraft coverage on debit card and ATM transactions.3FDIC.gov. Overdraft and Account Fees
One boundary to know: the opt-in rule does not cover checks or recurring electronic payments such as automatic bill pay and direct debits. Banks can pay those and charge a fee even if you never opted in.
Daily Limits on Overdraft Fees
No federal rule sets a maximum number of overdraft fees per day. The Office of the Comptroller of the Currency has said that charging fees without a daily limit, or with a very high one, has contributed to findings that a bank’s overdraft program is unfair under federal consumer protection law.4Office of the Comptroller of the Currency. Overdraft Protection Programs: Risk Management Practices That guidance has pushed most banks to adopt internal caps.
In practice, most major banks limit overdraft fees to between three and six per business day. Several large institutions cap charges at three fees daily. Once you hit the cap, additional overdrawn items are typically either covered at no extra charge or declined. Your account agreement will list your bank’s exact number.
Small-Balance Buffers
Many banks build in a “de minimis” threshold, a small cushion before any overdraft fee kicks in. If your account dips below zero by less than this amount, no fee is charged. The FDIC cites $10 as a common example, and CFPB data puts the average threshold at surveyed banks and credit unions at roughly $9.5CONSUMER FINANCIAL PROTECTION BUREAU. Data Point: Checking Account Overdraft at Financial Institutions Served by Core Processors Some banks go much higher: Huntington Bank waives fees when the account is overdrawn by less than $50, and Santander’s threshold is $100.
The buffer is all-or-nothing. If your balance falls to negative $4 at a bank with a $10 cushion, you owe nothing extra. At negative $11, the full fee applies. Federal rules require that overdraft fee information be disclosed clearly, so the exact figure is in your account agreement.6eCFR. 12 CFR 1030.11 – Additional Disclosure Requirements for Overdraft Services
Grace Periods and Extended Overdraft Fees
A growing number of banks now give you a window, usually around 24 hours, to bring your balance back above zero before charging an overdraft fee. That window lets you transfer money or make a deposit and avoid the charge entirely. The OCC has specifically encouraged grace periods as a risk-mitigating practice.4Office of the Comptroller of the Currency. Overdraft Protection Programs: Risk Management Practices Wells Fargo, U.S. Bank, and PNC are among the major institutions offering at least a 24-hour window before fees are assessed.
If your account stays negative for several days, some banks add a second layer known as an extended or sustained overdraft fee. These are assessed when you haven’t repaid the overdraft after a set period, such as five or more business days.2Consumer Financial Protection Bureau. 12 CFR Part 1005 (Regulation E) – Section 1005.17 Requirements for Overdraft Services The daily charges have historically ranged from $5 to $10 on top of the initial fee, though regulatory scrutiny has led many banks to reduce or eliminate them.7Consumer Financial Protection Bureau.

Multiple Fees for the Same Transaction
When a payment bounces, the merchant may resubmit it, sometimes more than once. Some banks have charged a separate NSF or overdraft fee each time the same transaction was re-presented, turning one failed payment into two or three fees. The FDIC has said this practice creates a heightened risk of violating federal consumer protection law and has urged banks to charge no more than one fee per transaction regardless of how often it is resubmitted.8Federal Deposit Insurance Corporation. Supervisory Guidance on Multiple Re-Presentment NSF Fees
Check your statements for identical fee amounts posted a few days apart. If you spot duplicates tied to the same payment, ask your bank to reverse them. This is one of the errors regulators take most seriously.
How to Push Back on Fees You’ve Already Paid
Start with your bank. Many will reverse one or more overdraft fees as a courtesy, particularly if you have a long account history or the fee resulted from a timing issue with a deposit. Be specific about which fee and why.
If your bank won’t help, file a complaint with the Consumer Financial Protection Bureau. The process takes about 10 minutes online, and the CFPB forwards the complaint to the bank, which generally must respond within 15 days.9Consumer Financial Protection Bureau. Submit a Complaint Fees charged without proper opt-in consent, unanticipated fees, and multiple fees for the same re-presented transaction are the categories regulators have flagged as potentially unfair or deceptive.10Consumer Financial Protection Bureau. Consumer Financial Protection Circular 2022-06: Unanticipated Overdraft Fee Assessment Practices
Prevention beats disputing. Opting out of overdraft coverage on debit card and ATM transactions eliminates the fee entirely for that category, since the bank must decline instead. For checks and recurring payments, which the opt-in rule doesn’t reach, low-balance alerts through your bank’s app give you time to move money before a charge posts.
