Few banking charges are as frustrating as an overdraft fee, especially when a small purchase triggers a much larger charge. Many banks have reduced or eliminated these fees in recent years, but they still exist at many institutions. Understanding how overdrafts work and the rules that protect you can help you avoid fees entirely.
What is an overdraft?
An overdraft happens when you spend more than the available balance in your checking account and the bank covers the transaction anyway. The bank may charge an overdraft fee for paying it. If the bank declines or returns the transaction instead, it may charge a non-sufficient funds (NSF) fee, though many large banks have stopped charging NSF fees.
Overdrafts can occur from:
- Debit card purchases
- ATM withdrawals
- Checks
- Automatic bill payments (ACH)
- Recurring subscriptions
The federal opt-in rule
Under Regulation E, banks cannot charge an overdraft fee on ATM withdrawals and one-time debit card transactions unless you have opted in to overdraft coverage for those transactions. If you do not opt in, those transactions will generally be declined when you lack funds, with no overdraft fee.
The opt-in rule does not apply to checks, recurring debit card payments, or ACH payments. Banks may pay those and charge a fee under the account agreement whether or not you opt in.
You can revoke your opt-in at any time by contacting your bank.
Overdraft protection options
Many banks offer ways to cover shortfalls that can cost less than standard overdraft fees:
- Linked savings account transfers: The bank moves money from your savings to checking when needed, sometimes for a small fee or none at all.
- Overdraft line of credit: A small credit line covers overdrafts, with interest charged on the amount borrowed.
- Linked credit card: Some banks allow a credit card to cover overdrafts, often treated as a cash advance with fees and high interest.
Compare the cost of each option to standard fees.
Available balance vs. current balance
Your current balance includes all posted transactions. Your available balance subtracts pending transactions and holds. Overdrafts are generally based on the available balance. Card authorizations, deposit holds, and pending payments can make your available balance lower than you expect.
Transaction ordering
The order in which a bank processes transactions affects how many fees you pay. Some banks process transactions in chronological order, while others have historically processed larger transactions first, which can create more overdrafts. Regulators have criticized certain practices, such as charging overdraft fees on transactions authorized when you had enough money but settled after your balance fell. Check your account agreement for how your bank orders transactions.
Recent changes in bank practices
Over the past several years, many major banks have:
- Eliminated NSF fees
- Reduced overdraft fees or capped the number per day
- Introduced grace periods allowing you to bring your balance back before a fee is charged
- Stopped charging fees on small overdrafts, such as those under a set dollar amount
- Eliminated overdraft fees entirely
A federal rule finalized in 2024 that would have limited overdraft fees at large banks was overturned by Congress in 2025, so fee policies are largely set by each bank within existing regulations. Credit unions are regulated separately and have their own policies.
An example
Suppose your checking account has $40 available. You buy groceries for $55 with your debit card, and later that day an automatic $30 utility payment posts. If you opted in to debit card overdraft coverage and your bank charges $35 per overdraft, you could pay $70 in fees for two transactions. If you had not opted in, the grocery purchase would likely have been declined with no fee, though the utility payment could still trigger a fee. If your bank linked your savings account, the shortfall might have been covered by a transfer instead.
How to avoid overdraft fees
- Opt out of overdraft coverage for debit card and ATM transactions if you prefer declines to fees.
- Set up low-balance alerts by text or email.
- Link a savings account for automatic transfers.
- Keep a buffer in checking.
- Time bill payments for after payday.
- Track pending transactions in your banking app.
- Choose a bank with no overdraft fees, including many online banks and credit unions.
- Use early direct deposit if your bank offers it.
How to get an overdraft fee refunded
Banks often waive fees as a courtesy, especially for customers with good history. Call customer service, explain what happened, and ask politely for a refund. If you believe a fee violated your agreement or the law, you can file a complaint with the Consumer Financial Protection Bureau or your bank’s regulator.
Repeated overdrafts and account closure
If your account stays negative, the bank may close it and send the balance to collections. It may also report the closure to specialty consumer reporting agencies such as ChexSystems, which can make it hard to open a new account. Many banks offer second chance or low-cost checking accounts for people with past banking problems, including accounts that do not allow overdrafts.
Overdraft fees and prepaid cards
Prepaid accounts are covered by federal rules that restrict overdraft features. Many prepaid cards simply decline transactions when there are insufficient funds. If a prepaid account offers overdraft credit, special rules apply, including waiting periods and limits on fees. Read the card’s fee disclosure before using it.
Checks and returned payments
When a check or ACH payment is returned for insufficient funds, the payee may charge its own returned-payment fee in addition to any bank fee. A returned rent or loan payment may also trigger late fees. To avoid a chain of fees, contact the payee quickly and arrange a replacement payment.
Budgeting to prevent overdrafts
A simple budget can prevent most overdrafts. List your fixed bills and their due dates, compare them with your pay dates, and keep enough money in checking to cover the next round of bills. Many people find it helpful to move discretionary spending money to a separate account or use a spending app that shows available funds after upcoming bills.
Choosing a checking account
When comparing accounts, review:
- Overdraft and NSF fee policies
- Whether overdraft coverage is optional
- Grace periods and small overdraft exemptions
- Linked savings transfer fees
- Monthly maintenance fees and how to waive them
- Early direct deposit features
- ATM network access
Banks must provide fee schedules, and many publish them online. A few minutes of comparison can save hundreds of dollars each year if overdrafts have been a recurring problem.
Overdrafts on joint accounts
On joint checking accounts, both owners are typically responsible for overdrafts and fees, regardless of who made the transaction. Communicate about large purchases and set up shared alerts.
When an overdraft might make sense
In rare cases, paying an overdraft fee may be less costly than the alternative, such as a returned rent payment, a late mortgage payment, or a lapsed insurance policy. Even then, a linked savings transfer or a quick call to the payee is usually cheaper. Weigh the fee against the consequences of a declined payment.
