Yes, you can overdraw your checking account, but the bank will charge you a fee

When you spend more money than you have in your checking account, the bank can cover the difference—but it costs you. Most banks charge an overdraft fee (usually $25 to $35 per transaction) when this happens. Some banks will reject the transaction instead and charge a smaller fee for the declined purchase. A few banks offer overdraft protection, which links your checking account to a savings account or credit line so money transfers automatically when you go negative, though this usually comes with its own fee.

The key thing to understand: overdrawing is not free, and the fees can pile up fast. If you make multiple purchases while overdrawn, you can be charged multiple overdraft fees in a single day. Some banks have daily caps on overdraft fees (often three per day), but not all do.

Key Takeaways

  • Overdraft fees typically range from $25 to $35 per transaction, and you can be charged multiple times in one day if you make several purchases while overdrawn.
  • Banks can either cover the overdraft and charge you a fee, or decline the transaction and charge a smaller fee—the bank chooses which approach to take.
  • Overdraft protection links your checking account to savings or a credit line so money transfers automatically, but this service usually costs money too.
  • Your bank must give you the option to opt out of overdraft coverage for debit card and ATM transactions, though opting out means those transactions will be declined instead.
  • Checking your balance before you spend and setting up account alerts can help you avoid overdrafts altogether.

How overdraft fees work at your bank

When a transaction would take your account below zero, your bank decides in real time whether to cover it or decline it. If the bank covers it, your account goes negative and you are charged an overdraft fee. If the bank declines it, the transaction fails and you are charged a smaller non-sufficient funds (NSF) fee instead—usually $10 to $20.

The bank is not required to cover overdrafts. It chooses to because overdraft fees are profitable. However, federal law requires banks to let you opt out of overdraft coverage for debit card purchases and ATM withdrawals. If you opt out, those transactions will simply be declined instead of triggering an overdraft fee. Check deposits and automatic bill payments typically cannot be opted out of—the bank will still cover those and charge a fee.

Some banks charge overdraft fees even if you only go negative by a few cents. Others have a grace period or a minimum overdraft amount (like $5) before they charge. Read your bank's overdraft policy in the account agreement or ask a teller what the exact rules are for your account.

Overdraft protection: how it works and what it costs

Overdraft protection is a service that automatically transfers money from another account (usually savings) or draws from a credit line when your checking account would go negative. This prevents the overdraft fee from being charged in the first place. However, the bank usually charges a fee for each transfer—often $10 to $15—so you are still paying, just a smaller amount than a full overdraft fee.

Overdraft protection only works if you have money in the linked savings account or available credit on the linked credit line. If you do not, the transfer fails and you get charged an overdraft fee anyway. Some banks offer overdraft protection through a line of credit, which means you are borrowing money and will owe interest on top of the transfer fee.

Before you set up overdraft protection, compare the transfer fee to your bank's overdraft fee. If your bank charges $35 per overdraft and overdraft protection costs $10 per transfer, protection might save you money. But if you overdraft frequently, you could end up paying $10 multiple times per month, which adds up fast.

What to do if you overdraw your account

If you notice your account is overdrawn, contact your bank as soon as possible. Some banks will waive one overdraft fee per year if you ask, especially if you have been a customer for a long time or if the overdraft was small. There is no may provide they will do this, but it is worth asking. Have your account number and the date of the overdraft ready when you call.

Deposit money into your account to bring the balance back to positive. Once you do, the overdraft fee has already been charged, but at least you stop the bleeding—no more fees will accrue. If you cannot deposit money right away, your account will stay negative and the bank may charge additional fees or close the account if it stays negative for too long (usually 30 to 60 days).

If your bank closed your account due to overdrafts, you may show up in ChexSystems, a banking history database that other banks check when you try to open a new account. This can make it harder to open a checking account elsewhere for a few years. Some banks specialize in second-chance accounts for people with ChexSystems records, though these accounts often have higher fees.

How to avoid overdrafting

Check your balance before you spend money. This sounds simple, but most overdrafts happen because someone did not realize how much money was actually in the account. Mobile banking apps make this easy—you can check your balance in seconds from your phone.

Set up low-balance alerts through your bank's app or website. These send you a text or email when your balance drops below a certain amount (you choose the threshold). If you set the alert at $200, for example, you will get a notification as soon as your balance hits $199, giving you time to deposit money or cut back on spending before you overdraft.

Keep a buffer in your checking account. If you keep at least $200 to $500 as a cushion that you do not spend, you have room for small mistakes or unexpected charges without going negative. This is not the same as an emergency fund—it is just money that stays in the account to prevent overdrafts.

Avoid linking too many subscriptions or automatic payments to your checking account. Each one is a chance to overdraft if you forget about it or if the charge is larger than expected. Review your automatic payments once a month to make sure they are still necessary.

Overdraft fees and your credit score

Overdraft fees themselves do not show up on your credit report and do not affect your credit score. However, if your account stays overdrawn for a long time and the bank sends it to a collection agency, that collection account will appear on your credit report and will hurt your score.

Banks typically send overdrawn accounts to collections after 30 to 60 days of being negative. Once that happens, the damage to your credit is done. It is much cheaper and easier to deposit money and bring your account back to positive before that point.

Frequently Asked Questions

Can a bank charge me multiple overdraft fees in one day?

Yes. If you make five debit card purchases while overdrawn, you can be charged five overdraft fees in a single day. Some banks cap overdraft fees at three per day, but not all. Check your bank's policy to see if there is a daily limit.

What is the difference between an overdraft fee and an NSF fee?

An overdraft fee is charged when the bank covers a transaction that would make your account negative. An NSF (non-sufficient funds) fee is charged when the bank declines a transaction because you do not have enough money. NSF fees are usually smaller, around $10 to $20, compared to overdraft fees of $25 to $35.

If I opt out of overdraft coverage, will my debit card be declined?

Yes. If you opt out of overdraft coverage for debit card transactions, any purchase that would overdraw your account will be declined at the point of sale. You will not be charged a fee, but the transaction will not go through. You can still opt back in at any time by contacting your bank.

Can I get an overdraft fee waived?

Some banks will waive one overdraft fee per year if you ask, especially if you have a good history with the bank. Call and explain the situation. There is no may provide they will do it, but it costs nothing to ask. Having a long account history and a good deposit record makes it more likely they will say yes.

Will overdrafting hurt my credit score?

Overdraft fees alone do not affect your credit score. However, if your account stays overdrawn for 30 to 60 days and goes to a collection agency, that collection account will appear on your credit report and will lower your score significantly.
