Your bank will cover the transaction, charge you a fee, and expect you to deposit money to bring your balance positive

When you spend more than you have in your checking account, your bank faces a choice: cover the transaction anyway (called an overdraft), or decline it. Most banks cover it and charge you an overdraft fee—typically $25 to $35 per transaction, though some banks charge more. You now owe the bank not just the amount you overspent, but also that fee. Your account balance goes negative, and you have a set number of days (usually 5 to 10 business days, depending on your bank) to deposit enough money to bring it back to zero or above.

If you don't deposit money in time, the bank may charge additional fees—sometimes called extended overdraft fees or sustained overdraft fees—every few days your account stays negative. Some banks will also close your account if you don't resolve the overdraft within a certain window, typically 30 to 60 days. Once an account is closed for overdraft, it gets reported to ChexSystems, a banking history database, and opening a new account at another bank becomes harder for months or years.

Key Takeaways

  • Each overdraft transaction triggers a separate fee from your bank, so one shopping trip can result in multiple charges if several purchases post before you notice.
  • You have a few days to deposit money and bring your balance positive; the exact window depends on your bank's policy.
  • If your account stays negative for 30 to 60 days without a deposit, the bank will close it and report you to ChexSystems, making it difficult to open accounts elsewhere.
  • Some banks offer overdraft protection (a linked savings account or credit line) that covers overdrafts automatically, though it may still carry a fee.
  • Opting out of overdraft coverage means transactions will be declined instead of covered, preventing fees but also preventing the purchase.

How overdraft fees stack up when multiple transactions post at once

Banks process transactions in a specific order, and that order matters. Deposits typically post first, then withdrawals—but withdrawals don't all post at the same time. If you make five debit card purchases on the same day but your bank processes them one at a time, and your balance dips below zero after the second purchase, you could be charged a fee for each of the remaining three transactions, even though they all happened on the same day.

Some banks also reorder transactions from largest to smallest before posting them, which can trigger more overdrafts. If you have $50 in your account and make a $10 purchase and a $60 purchase on the same day, the bank might process the $60 first, overdrafting you by $10, then process the $10 purchase, overdrafting you again. That's two fees instead of one—a practice called high-to-low posting that has been the subject of lawsuits and regulatory scrutiny.

Check your bank's transaction posting order in your account settings or by calling customer service. Some banks allow you to change this setting or disable it entirely.

What to do immediately after you notice an overdraft

Deposit money as soon as possible—enough to cover both the overdraft amount and the fee. If your account is $50 negative and the fee is $35, deposit at least $85. Use a method that posts quickly: a direct deposit from your employer, a transfer from another bank account you control, or a cash deposit at a branch or ATM if your bank offers that option. Mobile check deposit and online transfers typically post within one business day; wire transfers post the same day but cost $15 to $25.

Once the deposit posts and your balance is positive again, the overdraft is resolved—but the fee stays on your record. Call your bank's customer service line and ask whether they will reverse or waive the fee. Banks have discretion here, and many will reverse one overdraft fee per year if you have a clean history otherwise. Be direct: "I overdrafted on [date]. I've deposited money to cover it. Can you reverse the fee?" Some banks will, some won't, but asking takes five minutes and costs nothing.

If your bank refuses and this is your first overdraft in years, ask to speak to a supervisor or escalate through the bank's complaint process. Document the date, the amount, and the name of the person you spoke to. If the bank still refuses, you can file a complaint with the Consumer Financial Protection Bureau (CFPB) at consumerfinance.gov.

Overdraft protection: how it works and whether it's worth it

Overdraft protection is a service your bank offers to cover overdrafts automatically using money from another account or a credit line you set up in advance. The most common form links your checking account to a savings account at the same bank. If your checking balance goes negative, the bank transfers money from savings to cover it—usually in increments of $50 or $100. You still pay a fee (typically $10 to $15 per transfer, less than a standard overdraft fee), but you avoid the cascade of multiple fees from several transactions posting at once.

Some banks offer overdraft protection through a credit line instead—essentially a small loan that covers the overdraft. This costs more (interest charges plus a fee) but doesn't require you to have a linked savings account. A few banks offer it for free to customers who meet certain conditions, like maintaining a minimum balance or setting up direct deposit.

Overdraft protection is useful if you occasionally overspend by small amounts and have a savings account to draw from. It's not useful if you don't have savings to link, or if you're chronically overdrafting—in that case, the fees add up faster than they would without protection, and you're better off addressing the underlying spending or income problem.

Opting out of overdraft coverage to prevent fees entirely

You have the right to opt out of overdraft coverage. When you do, transactions that would overdraft your account are simply declined instead—your debit card is rejected at the register, or your online payment fails. You don't spend money you don't have, and you don't pay a fee. The downside is the embarrassment or inconvenience of a declined transaction, and the risk that a bill payment fails and triggers a late fee from the creditor instead.

To opt out, call your bank's customer service line or log into your online banking portal and look for overdraft settings. Some banks call it "opting out of overdraft coverage," others call it "declining overdraft protection." The setting may be buried in account preferences or security settings. Ask the bank to confirm in writing that you've opted out, and keep that confirmation.

Opting out is a good choice if you want to avoid fees and you can handle the occasional declined transaction. It's less useful if you have automatic bill payments set up, because a declined payment can trigger a late fee from the biller and damage your credit. If you go this route, make sure your checking account balance never dips below the amount of your largest automatic payment.

Recovering from a closed account and ChexSystems report

If your bank closes your account because of an unresolved overdraft, you'll receive a notice in the mail explaining the reason and the amount owed. Pay the full amount immediately—the overdraft balance plus all accumulated fees. Once you pay, the account is closed but the debt is settled. The bank will report the closure to ChexSystems, a database that other banks use to screen new account applications.

A ChexSystems report stays on file for five years. During that time, many banks will deny your application for a new checking account based on the report alone. Some banks specialize in second-chance checking and will open an account for you despite the report, but they often charge higher fees or require a larger minimum balance. Search online for "second chance checking" plus your state to find banks that work with people who have ChexSystems records.

You can request a copy of your ChexSystems report for free at chexsystems.com. If the report contains errors—for example, if it lists an overdraft you already paid, or an overdraft that wasn't your fault—you can dispute it. ChexSystems has 30 days to investigate and correct errors. If the information is accurate, you can add a consumer statement to your file explaining the circumstances, though this doesn't remove the record and doesn't may provide a bank will overlook it.

Preventing overdrafts: tracking and alerts

The simplest way to prevent overdrafts is to know your balance before you spend. Check your account balance in your bank's mobile app or online portal before making a purchase, especially if you're near your available balance. Remember that your available balance may be different from your current balance—available balance accounts for pending transactions that haven't posted yet, so it's the more accurate number to use.

Set up low-balance alerts in your bank's app or online portal. Most banks let you choose a threshold—for example, $100—and will send you a text or email whenever your balance drops below it. This gives you time to deposit money or adjust your spending before you overdraft. Some banks also offer alerts for large transactions or unusual activity.

If you use multiple payment methods (debit card, checks, online bill pay, automatic payments), keep a running total of pending transactions. Write them down or track them in a notes app. Banks don't always post transactions in real time, so a purchase you made this morning might not show up in your balance until tomorrow, and a check you wrote last week might not post for several days. Accounting for these delays prevents you from thinking you have more money than you actually do.

Frequently Asked Questions

Can a bank charge me a fee for every transaction that overdrafts, or is there a limit?

Banks can charge a separate fee for each transaction that overdrafts, with no federal limit on the total number of fees per day. However, some states have capped the number of overdraft fees a bank can charge per day (usually three to six), and the CFPB has proposed rules that would limit fees further. Check your state's banking regulations or ask your bank about daily fee caps in your state.

What's the difference between an overdraft and a non-sufficient funds fee?

An overdraft fee is charged when the bank covers a transaction even though you don't have enough money. A non-sufficient funds (NSF) fee is charged when the bank declines the transaction because you don't have enough money. The fee amount is usually the same, but NSF fees only apply if you haven't opted into overdraft coverage.

If I pay back the overdraft, will it hurt my credit score?

An overdraft itself does not appear on your credit report and does not directly hurt your credit score. However, if the overdraft goes unpaid for a long time and the bank closes your account and sends it to collections, that collections account will appear on your credit report and damage your score. Paying the overdraft quickly prevents this.

Can I dispute an overdraft fee if I think the bank made a mistake?

Yes. If you believe the bank charged you incorrectly—for example, if a transaction posted twice, or if the bank reordered transactions in a way that created unnecessary overdrafts—contact customer service and explain the error. Ask them to review the transaction history and reverse the fee if they find a mistake. If they refuse, you can file a complaint with the CFPB.

How long does it take for a deposit to post and clear an overdraft?

Direct deposits and transfers between accounts at the same bank typically post within one business day. Cash deposits at a branch or ATM post immediately. Mobile check deposits post within one to two business days. Once the deposit posts, your overdraft is cleared and any additional overdraft fees stop accruing, though fees already charged remain on your account.
