Yes, your checking account can go below zero, and the consequences depend on your bank and the transaction
Your checking account balance can drop below zero. When it does, you are overdrawn—you have spent money you do not have. What happens next depends on whether your bank allows overdrafts, whether you have overdraft protection, and how quickly you deposit funds to cover the shortfall.
Some banks will reject transactions that would take you below zero. Others will allow the transaction to go through and charge you an overdraft fee, usually between $25 and $35 per transaction. A few banks offer overdraft protection, which automatically transfers money from a linked savings account or credit line to cover the gap—often with a smaller fee or none at all.
The key difference is what you agreed to when you opened the account. Your account agreement spells out whether overdrafts are allowed and what the fees are. If you have never seen this agreement, your bank can send you a copy, and you can change your overdraft settings at any time.
Key Takeaways
- Banks can allow your account to go negative, but they are not required to—some reject transactions that would overdraw you instead.
- Each overdraft transaction typically costs $25 to $35 in fees, and multiple overdrafts in one day can add up quickly.
- Overdraft protection links your checking account to savings or a credit line so transfers happen automatically instead of fees being charged.
- You can turn overdraft protection on or off, and you can ask your bank to reverse overdraft fees if this is your first time or if the fee was caused by a bank error.
- Going overdrawn does not directly hurt your credit score, but it can lead to debt collection if the account stays negative long enough.
How overdraft fees work and when they are charged
When a transaction would take your account below zero and your bank allows it, the bank charges an overdraft fee. This fee is separate from the amount you are short—if you are $50 short and the fee is $35, you now owe $85.
The fee is charged per transaction, not per day. If you make five purchases that each overdraw your account on the same day, you could face five separate fees. Some banks cap the total fees per day (often at two or three), but not all do. This is why multiple small overdrafts can become expensive very quickly.
The fee is charged whether you overdraw by $1 or $100. There is no sliding scale—the bank charges the same amount either way. This is why overdraft fees hit hardest when you are already short on money.
Overdraft protection: how it works and whether it costs money
Overdraft protection is a service that covers overdrafts automatically instead of charging a fee. When a transaction would take you below zero, the bank transfers money from a linked account—usually a savings account at the same bank, or sometimes a credit line—to cover the gap.
The cost depends on the type of protection. If it is linked to your own savings account, there is usually no fee at all, just a transfer between your accounts. If it is linked to a credit line or a line of credit, you may pay a small fee (often $1 to $10) or interest on the borrowed amount. Some banks offer free overdraft protection for the first few transfers per year, then charge a fee after that.
You have to set up overdraft protection before you need it. You cannot turn it on after an overdraft happens. To set it up, contact your bank and ask which accounts or credit lines you can link. You can also turn it off at any time if you decide you do not want it.
What happens if you stay overdrawn for days or weeks
If your account stays negative for more than a few days, your bank may charge additional fees. Some banks charge a daily fee for accounts that remain overdrawn (sometimes called a sustained overdraft fee), usually $5 to $10 per day. Others charge a single fee after a set number of days, like 10 or 14 days.
If you stay overdrawn long enough—typically 30 to 60 days, depending on the bank—the bank may close your account and send the debt to a collection agency. At that point, you owe the bank the full negative balance plus all fees, and the debt can appear on your credit report. This does not happen overnight, but it does happen if you ignore the problem.
The best move is to deposit funds as soon as you realize you are overdrawn. Even a partial deposit stops the bleeding—it reduces the negative balance and may prevent additional fees from being charged. Call your bank if you are unsure how much you owe or when the next fee will be charged.
How to get overdraft fees reversed
Banks are not required to reverse overdraft fees, but many will if you ask, especially if this is your first overdraft or if the overdraft was caused by a bank error. The worst they can say is no.
Call your bank's customer service line and explain the situation. Be specific: say when the overdraft happened, how much it was, and why (if there is a clear reason—a delayed paycheck, an unexpected bill, a mistake on your part). If this is your first overdraft in years, mention that. If the bank made an error—a transaction posted out of order, a hold that should not have been there—explain that too.
Some banks have a formal process for this. They may ask you to submit a written request or fill out a form. Others handle it over the phone. Either way, it usually takes a few business days for the decision. If the bank reverses the fee, the money goes back into your account.
If your bank refuses and you believe the fee was unfair, you can file a complaint with the Consumer Financial Protection Bureau (CFPB) at consumerfinance.gov. The CFPB does not reverse fees directly, but it investigates complaints and can pressure banks to change their practices.
Overdrafts and your credit score
Going overdrawn does not directly hurt your credit score. Overdraft fees are between you and your bank—they do not appear on your credit report, and the credit bureaus do not track them.
However, if you stay overdrawn long enough and the bank sends the debt to a collection agency, that collection account will appear on your credit report and will damage your score. This typically happens 30 to 60 days after the account goes negative, depending on the bank.
The damage is real but not permanent. A collection account stays on your report for seven years, but its impact on your score fades over time, especially if you pay it off. Paying the debt in full does not remove the account from your report, but it does change the status to "paid" and improves your score somewhat.
How to avoid overdrafts in the first place
The simplest way to avoid overdrafts is to keep a buffer in your account—money you do not spend. Even $100 or $200 catches most overdrafts before they happen. If you live paycheck to paycheck and cannot build a buffer, set up overdraft protection linked to a savings account or credit line so fees are not charged.
You can also ask your bank to reject transactions that would overdraw you instead of allowing them. This is called opt-out or no overdraft mode. When you turn this on, your debit card will be declined if you do not have enough funds. This prevents overdraft fees but can be inconvenient if you are counting on a deposit to clear soon.
Check your account balance before making large purchases or paying bills. Many banks offer alerts—you can set your bank to text or email you when your balance drops below a certain amount, like $100. These alerts give you time to deposit funds before an overdraft happens.
Frequently Asked Questions
Can a bank close my account if I go overdrawn?
Yes. If your account stays negative for 30 to 60 days (the exact timeline varies by bank), the bank can close it and send the debt to a collection agency. You will owe the full negative balance plus all fees. Depositing funds before that important date prevents closure.
Will my bank let me overdraw, or will it reject the transaction?
It depends on your bank and your account type. Some banks allow overdrafts by default; others reject transactions that would overdraw you. Your account agreement says which one applies to you. You can also call your bank and ask, or log into your online account to check your overdraft settings.
What is the difference between overdraft fees and overdraft protection?
Overdraft fees are charges the bank levies when you spend money you do not have. Overdraft protection is a service that covers the shortfall automatically by transferring money from another account, usually with no fee or a small fee instead of the larger overdraft charge.
If I deposit money, does it cover the overdraft fees too?
No. If you are overdrawn by $50 and the fee is $35, depositing $50 brings your balance to zero but does not cover the fee. You owe both amounts. You need to deposit $85 to clear the overdraft and the fee.
Can I dispute an overdraft fee if I think it was unfair?
You can ask your bank to reverse it, especially if it is your first overdraft or if the bank made an error. There is no may provide, but many banks will reverse one fee per year if you ask. If the bank refuses, you can file a complaint with the Consumer Financial Protection Bureau.
