Your bank will charge you an overdraft fee, usually $25 to $35 per transaction that pushes the account 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. Most banks charge an overdraft fee — a flat amount per transaction that goes negative, not a percentage of how far over you went. A single purchase that takes your account from $50 to -$20 costs one fee. Five small purchases that each go negative cost five fees, even if the total overage is only $100.

The fee itself varies by bank. Most large national banks charge between $25 and $35 per overdraft. Some credit unions and online banks charge less, or charge nothing at all. A few banks charge a second fee if your account stays negative for more than a few days — sometimes called a sustained overdraft fee or extended overdraft fee. That second fee can hit you every day or every few days until you bring the account back to zero.

You will also owe the original amount you overspent. If you spent $20 more than you had, you owe that $20 back to the bank, plus the overdraft fee on top of it. The bank does not forgive the overage — it just covers it temporarily while charging you for the service.

Key Takeaways

  • Overdraft fees typically range from $25 to $35 per transaction that goes negative, and multiple transactions in one day can trigger multiple fees.
  • Some banks charge a second fee if your account stays negative for more than a few days, adding to the total cost.
  • You owe both the original overspent amount and the overdraft fee; the bank does not forgive the shortfall.
  • Opting out of overdraft protection stops the bank from covering transactions, which prevents fees but may cause checks or payments to bounce.
  • Bringing your account back to zero stops additional fees from accruing, but you still owe the fees already charged.

How overdraft protection works — and what it costs you

Most checking accounts come with overdraft protection turned on by default. This means the bank will process a transaction even if you do not have enough money, then charge you a fee for doing so. The transaction goes through, your account goes negative, and the fee appears on your statement days later.

Some banks offer a gentler version called overdraft transfer, where money automatically moves from a savings account or linked account to cover the shortfall instead of charging a fee. This only works if you have another account with money in it, and the bank must have set up the link beforehand. If you do not have a linked account with funds, the overdraft fee applies instead.

A few banks offer overdraft lines of credit, which work like a small loan. Instead of a flat fee, you pay interest on the amount you borrowed. This is usually cheaper than overdraft fees if you stay negative for more than a few days, but more expensive if you fix it quickly. You have to request this option — it does not come automatically.

What happens if you opt out of overdraft protection

You can tell your bank to stop covering overdrafts. When you do, transactions that would take your account negative straightforward will not process. A debit card purchase gets declined at the register. A check bounces. An automatic bill payment fails to go through. You avoid the overdraft fee, but the transaction does not happen.

A bounced check or returned payment can create its own problems. The merchant or creditor may charge you a returned-check fee (typically $20 to $40). If it is a utility bill or loan payment, missing the important date can trigger a late fee or damage your credit. Some landlords and employers view bounced checks as a serious problem.

Opting out makes sense if you want to avoid overdraft fees entirely and you can manage your balance carefully. It makes less sense if you have bills on autopay that you cannot afford to miss, or if you regularly spend close to your balance and cannot predict exactly when money will arrive.

How long you have to fix a negative balance

There is no legal important date to bring your account back to zero. However, your bank can close your account if you stay negative for too long — usually between 30 and 60 days, depending on the bank's policy. Once the account is closed, any remaining balance becomes a debt you owe the bank.

If you do not pay that debt, the bank may send it to a collection agency or report it to ChexSystems, a banking history database. A ChexSystems report can make it difficult to open a new checking account elsewhere for up to five years. Some banks check ChexSystems before opening an account and will deny you if you have an unpaid overdraft on record.

The practical timeline is shorter: bring your account positive within a week or two if you can. Each day it stays negative, you risk another sustained overdraft fee. The longer you wait, the more fees accumulate and the harder it becomes to catch up.

Overdraft fees and your credit score

Overdraft fees themselves do not appear on your credit report and do not directly damage your credit score. The bank does not report overdrafts to the three major credit bureaus — Equifax, Experian, and TransUnion.

However, what comes after an overdraft can hurt your credit. If you do not pay back the negative balance and the bank sends it to a collection agency, that collection account will appear on your credit report and lower your score. If you miss a bill payment because an overdraft caused the payment to fail, and you do not catch up within 30 days, that missed payment gets reported and damages your score.

The overdraft itself is a warning sign that you should fix your balance quickly, not because of credit reporting, but because of the fees and the risk of collection.

Disputing an overdraft fee

You can ask your bank to reverse an overdraft fee, especially if it is your first one or if the fee was caused by a bank error. Banks are not required to reverse fees, but many will do so once per year or once per account lifetime if you ask politely and have a reasonable explanation.

Common reasons banks accept for reversal: the overdraft was caused by a delayed deposit that the bank should have processed sooner, you were not aware overdraft protection was on, or you have been a customer in good standing for years. Reasons banks usually reject: you knew you were low on funds and spent anyway, or you are asking for the third reversal in a year.

Call your bank's customer service line and ask to speak with someone who can review the fee. Have your account number and the date of the transaction ready. Be specific about why you think the fee should not have happened. If the first person says no, ask to speak with a supervisor. Some banks have a formal dispute process; others handle it case by case.

Preventing overdrafts before they happen

The simplest prevention is to keep a buffer — a small amount of money you do not spend, usually $100 to $300 depending on your income. This cushion means a small mistake or unexpected charge does not when ready take you negative.

Set up account alerts through your bank's app or website. Most banks let you choose a balance threshold — for example, $200 — and send you a text or email when your balance drops below it. This gives you time to move money in or pause spending before you go negative.

If you receive paychecks on a regular schedule, do not spend as if the money is already there. Wait until the deposit actually clears before counting it. Banks show deposits as "pending" for a day or two; spending based on pending deposits is a common cause of overdrafts.

If you use multiple accounts, keep your spending account separate from your savings account. This makes it harder to accidentally overdraft, because you have to deliberately transfer money to spend it.

Frequently Asked Questions

Can a bank refuse to cover an overdraft and just decline the transaction instead?

Yes. Banks are not required to offer overdraft protection. Some banks decline transactions that would go negative instead of covering them. You can also request that your bank stop covering overdrafts. The tradeoff is that transactions fail instead of going through, which can cause checks to bounce or bill payments to miss their due date.

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

An overdraft fee is charged when the bank covers a transaction that takes your account negative. A non-sufficient funds (NSF) fee is charged when the bank declines a transaction because you do not have enough money. Some banks use the terms interchangeably, but the outcome is different: overdraft means the transaction went through and you owe the bank money; NSF means the transaction did not go through and the merchant did not get paid.

If I go negative on a Friday, when will the overdraft fee show up?

Usually within one to three business days, so by Monday or Tuesday. Banks process overdraft fees in batches, not when ready. The fee will appear on your statement and reduce your balance further, which can trigger additional fees if your account stays negative. Check your account daily while it is negative so you know exactly what you owe.

Can I get my bank to waive overdraft fees if I have been a customer for a long time?

Many banks will reverse one overdraft fee per year or per account lifetime if you ask, especially if you have been a customer for several years and have not had overdrafts before. There is no may provide, but it is worth calling and asking. Banks are more likely to help if you explain what happened and ask respectfully rather than demanding a reversal.

What happens if I move to a new bank while my old account is still negative?

The negative balance stays with your old bank. You owe that money regardless of whether you still use the account. If you do not pay it, the bank can send it to a collection agency or report it to ChexSystems, which will make it harder to open accounts at other banks. Pay off the negative balance before closing the account, or at least before you stop checking it.
