Your bank sets the overdraft limit, not you
Your overdraft limit is decided by your bank based on your account history, balance patterns, and the type of account you hold. Banks do not publish a standard formula—each institution uses its own criteria. Some banks offer no overdraft protection at all. Others may allow overdrafts of $100 to $1,000 or more, depending on how long you have banked with them and how you have managed your account.
You cannot request a specific overdraft limit the way you would request a credit limit increase. Instead, your bank assigns one behind the scenes. If you want to know your actual limit, you need to contact your bank directly—call the number on your debit card, log into your online banking portal, or visit a branch. Many banks will tell you the limit over the phone in minutes.
The limit your bank gives you is not a permission to overdraft. It is the maximum amount the bank will cover before declining a transaction or charging you fees. Going over that limit means your transaction gets rejected, and you may still face a fee for the attempt.
Key Takeaways
- Your bank sets your overdraft limit based on your account history and balance patterns, and you cannot choose the amount yourself.
- Overdraft limits typically range from $100 to $1,000 or more, but some banks offer no overdraft protection at all.
- You can find your current limit by calling your bank, checking your online account, or visiting a branch in person.
- Staying within your overdraft limit does not protect you from fees—each overdraft transaction usually costs $25 to $35 per occurrence.
- Opting out of overdraft protection stops your bank from covering overdrafts, which prevents fees but may cause transactions to be declined.
How banks calculate your overdraft limit
Banks look at several factors when deciding how much they will cover if your account goes negative. The most common are your account age (how long you have been a customer), your average balance, your direct deposit history, and whether you have overdrafted before and repaid it promptly.
A customer with a five-year account history, steady direct deposits, and no overdraft incidents may receive a higher limit than someone with a new account or a pattern of overdrafts. Some banks also consider your credit score, though this is less common for checking account overdraft limits than for credit products.
Banks also distinguish between different account types. A premium checking account or one with a higher minimum balance requirement may come with a higher overdraft limit than a basic account. If you switch to a different account tier, your limit may change.
The difference between overdraft protection and overdraft fees
Overdraft protection is a service your bank offers to cover transactions when your balance is too low. Without it, your debit card transaction gets declined at the register. With it, the bank pays the merchant and your account goes negative. You then owe the bank that money plus an overdraft fee.
You can turn overdraft protection on or off. Many banks enable it by default for debit card and ATM transactions, but you can call and ask them to disable it. If you disable it, transactions will be declined instead of covered, and you will avoid overdraft fees—but you will also face the embarrassment of a declined card and may miss payments you intended to make.
Some banks offer overdraft transfer as an alternative. Instead of charging a fee, the bank transfers money from a linked savings account or credit line to cover the shortfall. This costs less than an overdraft fee, usually $0 to $10 per transfer, but only works if you have another account linked and funded.
What happens when you exceed your overdraft limit
If you try to overdraft beyond your limit, the transaction is declined. Your bank will not cover it. You will not incur an overdraft fee for that specific transaction because the bank refused to process it. However, you may face a fee for the declined transaction attempt itself—some banks charge $15 to $25 for this.
If you have multiple transactions pending and your balance is very low, the order in which your bank processes them matters. Banks typically clear transactions in a specific order (often largest to smallest, or in the order received), which can cause some transactions to overdraft while others are declined. Each overdraft incurs a separate fee.
Once you exceed your limit, your bank may also freeze your account or restrict future transactions until you bring your balance positive. Some banks will close your account if you remain overdrawn for 30 to 60 days without repaying.
How overdraft fees stack up
Each overdraft transaction typically costs $25 to $35. If you overdraft multiple times in one day, you can face multiple fees. A single day of heavy spending on an overdrawn account can result in $75 to $150 in fees alone.
Some banks cap the number of overdraft fees you can incur in a single day (often three to five), but not all do. Others cap the total fees per month. Check your account agreement or ask your bank what their fee cap is, if one exists.
Interest also accrues on the overdrawn balance itself. If your account stays negative for more than a few days, you will owe interest on top of the fees. The interest rate varies by bank but is typically much higher than a credit card rate—sometimes 20% or more annually.
How to find out your specific overdraft limit
Call your bank's customer service number (on the back of your debit card) and ask directly: "What is my overdraft limit?" They can tell you in seconds. Have your account number ready.
Log into your online banking portal or mobile app. Some banks display your overdraft limit in the account details or settings section. Not all banks show this information online, so if you do not see it, a phone call is faster than searching.
Visit a branch in person. A teller can look up your limit and explain how your bank's overdraft protection works. This is also a good time to ask whether you can increase your limit or switch to overdraft transfer instead of fees.
Whether to keep overdraft protection on or turn it off
Keeping overdraft protection on means you will not face declined transactions, but you will pay fees if you overdraft. This works if you overdraft rarely and can repay quickly. It fails if you overdraft frequently or stay overdrawn for weeks.
Turning overdraft protection off means transactions will be declined when your balance is too low. This prevents fees but can damage your credit if you miss bill payments, and it creates the inconvenience of a declined card. It also does not protect you from NSF (non-sufficient funds) fees on checks or automatic payments that your bank processes differently.
A middle ground is to keep overdraft protection on for bill payments and automatic transfers (which are harder to decline) but turn it off for debit card purchases (which you can control in the moment). Ask your bank whether they allow you to set different rules for different transaction types.
Frequently Asked Questions
Can I increase my overdraft limit?
You cannot request a higher limit directly, but your limit may increase automatically as your account history grows and your balance patterns improve. If you want to explore options, call your bank and ask whether they offer overdraft limit increases or whether switching to a premium account tier would raise your limit.
Do I have to pay back an overdraft when ready?
No, but the sooner you repay, the less interest you will owe. Most banks give you a grace period of a few days before interest starts accruing. Check your account agreement for your bank's specific timeline. If you do not repay within 30 to 60 days, your bank may close your account and report you to ChexSystems, a checking account history database.
What is the difference between an overdraft and a bounced check?
An overdraft occurs when your bank covers a transaction and your account goes negative. A bounced check occurs when your bank refuses to cover it and returns the check unpaid. With overdraft protection on, checks are covered (overdraft). With it off, checks bounce. Both result in fees, but overdraft fees are usually higher.
Can my bank lower my overdraft limit without telling me?
Yes. Banks can reduce your limit at any time based on account activity, missed payments, or policy changes. You will not receive advance notice. If you want to know whether your limit has changed, ask your bank directly during your next call or visit.
What happens if I overdraft and never repay?
Your bank will eventually close your account and may send it to a debt collector. You will be reported to ChexSystems, making it difficult to open a checking account at another bank for several years. The bank may also pursue legal action to recover the debt, depending on the amount and your state's laws.
