How overdrafts work
An overdraft happens when you withdraw or spend more money than you have in your account. Your bank can cover the shortfall temporarily — letting the transaction go through even though your balance would go negative — or it can decline the transaction and charge you a fee for trying.
Whether your bank covers an overdraft depends on whether you have overdraft protection set up. This is not automatic. You have to opt in, usually when you open the account or later through your bank's website or app. Without it, most transactions that would overdraw your account straightforward get rejected at the point of sale.
If you do have overdraft protection and you overdraw, your bank charges you a fee — typically between $25 and $35 per overdraft, though this varies by bank. Some banks charge a fee for each transaction that overdraws you; others charge one fee per day regardless of how many transactions occur. You also owe the bank the money you borrowed, usually without interest, though the debt is due when ready.
Key Takeaways
- Overdraft protection is optional and must be turned on deliberately — your bank will not automatically cover overdrafts unless you ask them to.
- Each overdraft typically costs $25 to $35 in fees, and multiple overdrafts in one day can result in multiple fees depending on your bank's policy.
- Without overdraft protection, transactions that would overdraw your account are straightforward declined, and you may still be charged a fee for the declined transaction attempt.
- The money you overdraw is not a loan with a payment plan — the bank expects you to deposit enough to cover it as soon as possible.
Opting in to overdraft protection
When you open a checking account, your bank will ask whether you want overdraft protection. The question is sometimes phrased as "overdraft coverage" or "overdraft opt-in." If you say yes, the bank will cover overdrafts up to a limit they set — often $100 to $500, depending on your account history and the bank.
You can change this decision at any time. Log into your bank's website or app, look for account settings or preferences, and search for "overdraft" or "overdraft protection." You can turn it on or off. Some banks also let you set a limit — for example, you might allow overdrafts up to $100 but not beyond that.
If you already have overdraft protection and want to turn it off, do that now if you are worried about overdrawing. Once it is off, transactions that would overdraw your account will be declined instead, which is safer but means you might be embarrassed at checkout or unable to complete a purchase you were counting on.
What happens when ready after an overdraft
The moment your account goes negative, your bank deducts the overdraft fee — usually $25 to $35. Your balance drops further. If you had $50 in your account and spent $75, you now owe the bank $50 (the $75 you spent minus the $50 you had) plus the fee, for a total of roughly $75 to $85 in the red.
Your bank will send you a notice, usually by email or text, telling you that you have overdrawn and what the fee was. Some banks give you a grace period — a few hours to a few days — to deposit money and avoid the fee. This varies widely. A few banks waive the first overdraft fee per year if you are a new customer or have a good history.
You need to deposit money to cover the overdraft as soon as you can. The bank is not waiting for a payment plan. If you do not deposit enough to bring your balance back to zero or positive, you may face additional fees or your account may be closed.
Overdraft fees can pile up quickly
If you overdraw multiple times in one day, you can be charged multiple fees. Some banks charge one fee per transaction that overdraws you. Others charge one fee per day, no matter how many transactions occur. A few charge both — a fee per transaction plus a daily cap. Check your account agreement or call your bank to find out which rule applies to you.
If you are already overdrawn and you make another purchase, that purchase might also trigger a fee. This is how people can end up with $100 or more in overdraft fees in a single week. The fees themselves make it harder to get back to a positive balance, which can lead to more overdrafts.
Some banks will reverse one or two overdraft fees if you call and ask, especially if you have been a customer for a while and this is unusual for you. It never hurts to ask, but do not count on it. The better move is to prevent overdrafts in the first place by keeping a buffer in your account — money you do not spend, so you never accidentally go negative.
Overdrafts versus declined transactions
If you do not have overdraft protection, your transaction will be declined. You will not overdraw, but you also will not get what you were trying to buy. Some merchants charge a fee for a declined transaction attempt — usually $1 to $3 — though many do not.
A declined transaction is embarrassing in the moment, but it costs less than an overdraft fee and it forces you to notice that you do not have enough money. An overdraft lets the transaction go through, which feels better when ready but costs more and can hide a spending problem until fees pile up.
Neither option is ideal. The real goal is to know your balance before you spend and to keep enough money in your account that neither situation happens.
How overdrafts affect your banking history
Overdrafts do not show up on your credit report. They do not hurt your credit score. However, they do show up in your banking history, which is tracked by a system called ChexSystems. If you overdraw repeatedly and do not pay it back, your bank may close your account and report you to ChexSystems. This makes it harder to open a new account at another bank.
Banks check ChexSystems when you explore for a new account. If you have a history of unpaid overdrafts, some banks will deny you. Others will offer you a second-chance account with lower limits and higher fees. This is why it matters to resolve overdrafts quickly — not just to avoid fees, but to protect your ability to bank elsewhere.
Alternatives to overdraft protection
If you are worried about overdrafting, you have other options. The simplest is to turn off overdraft protection and let transactions be declined. It is not pleasant, but it is free and it prevents debt.
Some banks offer overdraft lines of credit, which work like a small loan attached to your account. If you overdraw, the bank lends you the money at an interest rate — usually 15% to 20% annually. You pay interest on what you borrow, but you avoid the flat overdraft fee. This is only useful if you overdraw regularly and for large amounts; for occasional small overdrafts, the fee is cheaper.
The best alternative is to link your checking account to a savings account at the same bank and set up automatic transfers. If your checking account balance drops below a certain amount, the bank automatically moves money from savings to checking. This costs nothing and prevents overdrafts entirely. You need to have money in savings first, but if you do, this is the safest option.
Frequently Asked Questions
Can I overdraw my account at an ATM?
Yes, if you have overdraft protection. ATM withdrawals are treated like any other transaction. If you try to withdraw more than you have, the bank will either let it go through and charge you a fee, or decline the withdrawal. Check your receipt or your bank app when ready after to see if you overdrawed.
What if I overdraw and never deposit money to cover it?
Your bank will eventually close your account. The exact timeline varies, but most banks close accounts after 60 to 90 days of being overdrawn. You will still owe the money, and the bank may send it to a collection agency. This will hurt your ability to open a bank account elsewhere.
Do overdraft fees count toward my bank's fee limit?
No. Most banks have a daily cap on overdraft fees — usually three to five fees per day — but this is a limit on how many fees they will charge, not a limit on how much you owe. You still owe all the money you spent, plus all the fees charged, even if the bank stops charging new fees after the cap is reached.
Can I get an overdraft fee reversed?
Sometimes. If you have been a customer for a while and this is your first overdraft, call your bank and ask politely. Many banks will reverse one fee as a courtesy. If you overdraft regularly, they are less likely to help. There is no harm in asking, but do not count on it.
Is overdraft protection the same as a credit card?
No. A credit card is a separate account with its own limit and interest rate. Overdraft protection is a feature of your checking account that lets you borrow against your own money temporarily. Credit cards report to credit bureaus; overdrafts do not. Credit cards charge interest; overdrafts charge flat fees.
