Your bank will charge you an overdraft fee, usually $25 to $35 per transaction that pushes you below zero

When you spend more money than you have in your checking account, the bank covers the difference temporarily. That coverage is not free. You will be charged an overdraft fee — sometimes called an insufficient funds fee or NSF fee — for each transaction that goes through while your balance is negative. Most banks charge between $25 and $35 per overdraft, though some charge as much as $38 or more.

The fee itself makes your balance even more negative. If you had $10 in your account and spent $50, you now owe the bank $40 plus the overdraft fee, which could bring you to $65 or $75 in the red. If multiple transactions hit your account on the same day, you can be charged multiple overdraft fees — sometimes three, four, or more in a single day.

The bank does not have to cover the transaction at all. They choose to, and they charge you for the choice. Some banks will decline the transaction instead, which avoids the overdraft fee but may cause other problems — a check bounces, a bill payment fails, or a merchant declines your card.

Key Takeaways

  • Each transaction that overdrafts your account triggers a separate fee, and multiple overdrafts on the same day can result in multiple fees stacking up.
  • Your bank is not required to cover overdrafts; they can decline transactions instead, which avoids the fee but may cause checks to bounce or payments to fail.
  • Overdraft protection, if you have it, transfers money from another account to cover the shortfall, but you may still pay a fee for the transfer.
  • You have a limited window — usually a few business days — to deposit money and bring your account positive before the bank takes further action.
  • Repeated overdrafts can result in your account being closed and your name being reported to ChexSystems, which affects your ability to open accounts elsewhere.

How overdraft fees compound quickly

The math of overdrafts gets worse fast because fees stack. Imagine you have $50 in your account and three transactions hit on the same day: a $40 debit card purchase, a $20 automatic bill payment, and a $15 gas station charge. Each one individually would overdraft you. Depending on the order your bank processes them, you could be charged three separate $30 overdraft fees — $90 in fees alone — on top of the $75 in transactions you actually made.

Some banks process transactions in a way that maximizes overdraft fees. They might process larger transactions first, which causes smaller ones to overdraft when they otherwise would not have. This practice is called high-to-low sorting, and while some banks have moved away from it, others still use it. Check your bank's transaction processing order in their account agreement or by calling their customer service line.

The fees do not stop after one day. If you remain negative for several days, some banks charge a daily or weekly fee — sometimes called a sustained overdraft fee — on top of the per-transaction fees. This can add $5 to $10 per day to what you owe.

What happens if you do not pay the overdraft back

If you leave your account negative for more than a few days without depositing money, your bank will send you a notice. The notice gives you a important date — usually 5 to 10 business days — to bring your account current. This is your chance to deposit money and pay back what you owe, including all fees.

If you do not respond by the important date, the bank will close your account. They will keep any deposits you make to cover the negative balance and fees, and they may send the remaining debt to a collection agency. A closed account for overdraft appears on your banking history and is reported to ChexSystems, a consumer reporting agency that tracks banking problems. Other banks check ChexSystems when you try to open a new account, and a negative mark can make it difficult or impossible to open a checking account elsewhere for several years.

The bank can also pursue you legally for the debt, though most do not for small amounts. If they do sue and win, they can garnish your wages or place a lien on your property, depending on your state's laws.

Overdraft protection and how it works

Some banks offer overdraft protection, which automatically transfers money from another account — usually a savings account or line of credit — to cover the shortfall. This prevents the transaction from being declined and stops the overdraft fee from being charged. However, the transfer itself may cost you a fee, typically $1 to $10 per transfer, which is usually cheaper than an overdraft fee but not free.

Overdraft protection only works if you have another account with money in it or a credit line attached to your checking account. If you do not, the protection does nothing. You can request overdraft protection from your bank, but they do not have to grant it — they will look at your account history and creditworthiness first.

Some banks automatically enroll new customers in overdraft protection as a default. Read your account agreement or call your bank to find out whether you have it. If you do not want it, you can opt out, which means the bank will decline transactions that would overdraft you instead of covering them.

Opting out of overdraft coverage

You have the right to opt out of overdraft coverage, which means the bank will decline transactions that would take you below zero instead of covering them and charging you a fee. This prevents overdraft fees entirely, but it also means your debit card will be declined at the register, checks will bounce, and automatic bill payments may fail.

A declined transaction can have its own costs. A merchant may charge you a fee for a failed payment, or a utility company may charge a late fee if your bill payment bounces. A bounced check can damage your relationship with the payee and may result in them refusing to accept checks from you in the future. However, these costs are usually smaller than overdraft fees, and you have more control over when they happen.

To opt out, contact your bank directly — by phone, in person, or through your online account settings. Ask specifically to opt out of overdraft coverage for debit card transactions and ATM withdrawals. Some banks allow you to opt out of one but not the other. Get written confirmation of your opt-out request and keep it for your records.

How to recover from a negative balance

If your account is negative, your first step is to deposit money as soon as possible. Deposit at least enough to cover the negative balance plus all fees. You can deposit cash at an ATM, transfer money from another bank account, have someone send you money via a peer-to-peer payment app, or deposit a check. The faster you deposit, the faster you stop accumulating additional fees.

Once your account is positive again, contact your bank and ask them to reverse or waive the overdraft fees. Banks do not have to do this, but many will reverse one or two fees if you have a good account history and this is your first time asking. Be polite and honest about what happened. If the bank refuses, ask to speak to a supervisor or manager — sometimes they have more authority to waive fees than the first person you speak to.

If your account has been closed due to overdraft, you will need to pay the full negative balance before you can open a new account at that bank. Some banks will not let you open a new account at all if you have a recent closure for overdraft. In that case, you may need to use a second-chance checking account, which has higher fees but is designed for people with banking problems. Credit unions sometimes offer these accounts with lower fees than traditional banks.

Preventing overdrafts before they happen

The most reliable way to avoid overdraft fees is to keep a buffer in your account — money you do not spend. A buffer of $100 to $200 means that small mistakes or unexpected charges will not push you negative. This is not always possible if you live paycheck to paycheck, but even $20 or $30 can prevent some overdrafts.

Set up account alerts through your bank's app or website. Most banks allow you to set a low-balance alert that notifies you when your balance drops below a certain amount — say, $50. This gives you time to deposit money or adjust your spending before you go negative. Some banks also offer alerts when a large transaction is about to post.

Track your spending carefully. Write down every transaction — debit card purchases, checks, automatic payments, transfers — and subtract it from your balance as it happens, not when it clears. This is especially important for automatic payments and checks, which can take several days to clear. If you are not sure when something will post, assume it has already posted and do not spend that money.

Frequently Asked Questions

Can the bank charge me multiple overdraft fees on the same day?

Yes. Each transaction that overdrafts your account is charged separately, so if four transactions hit on the same day while you are negative, you could be charged four overdraft fees. Some banks cap the number of overdraft fees per day — usually at three or four — but not all do. Check your account agreement or call your bank to find out their policy.

What is the difference between overdraft and insufficient funds?

Overdraft means the bank covered the transaction and charged you a fee. Insufficient funds means the bank declined the transaction because you did not have enough money. The fee for insufficient funds is usually the same as an overdraft fee, but the transaction did not go through. Some banks use the terms interchangeably.

Will going negative hurt my credit score?

Overdrafts do not directly appear on your credit report, so they do not hurt your credit score. However, if the bank sends your debt to a collection agency and it goes unpaid, that collection account will appear on your credit report and damage your score. Additionally, a closed account for overdraft is reported to ChexSystems, which affects your ability to open new bank accounts but not your credit score.

Can I dispute an overdraft fee?

You can ask your bank to reverse or waive the fee, and they may do so if you have a good history or if the fee was caused by an error on the bank's part. However, you cannot formally dispute an overdraft fee the way you can dispute a fraudulent transaction. Your only option is to ask the bank directly and escalate to a manager if the first person says no.

What happens if I ignore overdraft notices from my bank?

If you ignore the bank's notice to bring your account current, they will close your account and report it to ChexSystems. The negative mark will stay on your banking history for several years, making it hard to open accounts elsewhere. The bank may also send your debt to a collection agency, which can pursue you for payment and damage your credit if it goes unpaid.
