What happens when you spend more than you have
An overdraft occurs when you withdraw or spend more money than sits in your account. Your bank can choose to cover the shortfall — paying the merchant or person you sent money to — which puts your account balance into negative numbers. You then owe the bank that amount plus an overdraft fee, usually between $25 and $35 per transaction, though some banks charge more.
The bank is not required to cover overdrafts. It is a choice they make, and they can change that choice at any time. Some banks automatically cover overdrafts on debit card purchases and checks. Others decline the transaction instead, which stops the overdraft from happening but may trigger a separate "insufficient funds" or "declined transaction" fee — often the same price as an overdraft fee.
Overdrafts are common because they happen without warning. You might think you have $200 in your account, spend $180 on groceries, then discover a $50 automatic payment posted the same day. The bank covers all three transactions, your balance drops to negative $30, and you are charged an overdraft fee on top of that.
Key Takeaways
- Your bank decides whether to cover overdrafts; they can refuse to do so, and you can ask them to turn overdraft coverage off.
- Each overdraft transaction typically costs $25 to $35 in fees, and multiple transactions on the same day can trigger multiple fees.
- Overdraft fees compound quickly because you owe the bank the negative balance plus the fee, and interest may accrue on top of that.
- Checking your balance before spending and setting up low-balance alerts are the most direct ways to avoid overdrafts.
- If you overdraft repeatedly, switching to a bank with no overdraft fees or lower fees may save you hundreds of dollars per year.
How overdraft fees stack up in a single day
Banks process transactions in an order that is not always the order you made them. Many banks process larger transactions before smaller ones, or process checks before debit card purchases. This matters because each transaction that puts your account negative can trigger its own overdraft fee.
Imagine you have $100 in your account. You make a $60 debit card purchase, a $30 check, and a $20 debit card purchase — all on the same day. If the bank processes the $60 first, your balance is $40. Then the $30 check brings you to $10. Then the $20 purchase brings you to negative $10, and you are charged one overdraft fee. But if the bank processes the $60 and $30 and $20 in a different order, you could end up with three separate negative balances and three separate fees — costing you $75 to $105 instead of $25 to $35.
This is why the order matters. You cannot control it, but your bank can tell you how they order transactions if you ask. Some banks have changed their ordering rules in recent years to reduce the number of overdraft fees customers pay, but not all have.
When overdraft protection is actually a trap
Some banks offer "overdraft protection," which sounds helpful but often works against you. Overdraft protection usually means the bank links your checking account to a savings account or credit line. If you overdraft your checking account, the bank automatically transfers money from the linked account to cover it — and charges you a fee for the transfer, usually $10 to $15.
The trap is that this fee is often cheaper than an overdraft fee, so it seems like a good deal. But it encourages you to overdraft repeatedly because the consequence feels smaller. Over a year, ten transfers at $12 each cost you $120 — money you would not have spent if the bank had straightforward declined the transaction instead.
Overdraft protection also drains your savings account without you noticing. You might think your savings is untouched when it is actually being used to cover checking account shortfalls. If you have overdraft protection, check whether it is actually turned on, and consider turning it off if you find yourself using it regularly.
How to prevent overdrafts before they happen
The simplest way to avoid overdrafts is to know your balance before you spend. This sounds obvious, but most overdrafts happen because people spend based on what they think they have, not what they actually have. Check your balance in your bank's app or website when ready before any large purchase, or before you know a big automatic payment is coming.
Set up a low-balance alert if your bank offers one. You can usually choose the dollar amount — for example, $50 or $100 — and the bank will text or email you when your balance drops below that number. This gives you time to move money in or pause spending before you overdraft. Most banks offer this for free.
If you receive paychecks on a regular schedule, mark those dates on your calendar and plan your spending around them. Do not spend money you are expecting to receive; spend only what is actually in your account right now. If you have irregular income, keep a larger cushion — money you do not touch — so that a slow month does not trigger overdrafts.
What to do if you overdraft by accident
If your account goes negative, contact your bank as soon as you notice. Many banks will reverse one overdraft fee per year if you ask, especially if you have been a customer for a while and do not overdraft regularly. This is not a may provide — it depends on the bank and your history — but it is worth asking.
Bring your account back to zero or positive as quickly as you can. While your account is negative, you are usually paying interest on the negative balance, which means the amount you owe grows every day. Some banks charge interest at a rate of 18% or higher on negative balances, so a $50 overdraft can cost you an extra $9 in interest over a year if you do not pay it back quickly.
After you pay back the overdraft, review what caused it. Was it a surprise automatic payment you forgot about? A miscalculation of your balance? A transaction that posted on an unexpected date? Once you know the cause, you can take steps to prevent it next time — setting a reminder, adjusting your budget, or switching banks if overdrafts are a recurring problem.
Banks and accounts with lower or no overdraft fees
Not all banks charge overdraft fees. Some online banks and credit unions do not offer overdraft coverage at all — they straightforward decline transactions that would overdraft your account. This means you cannot spend money you do not have, but it also means you cannot be surprised by overdraft fees.
Other banks charge lower overdraft fees than the $25 to $35 standard. Some charge $15 per overdraft, or charge a fee only if your account stays negative for more than a day. A few banks offer a small number of free overdrafts per year — for example, one free overdraft per month — before charging fees on additional overdrafts.
If you overdraft frequently, the cost difference between banks adds up quickly. If you overdraft four times a year at a bank charging $35 per overdraft, you pay $140 per year in fees. Switching to a bank charging $15 per overdraft, or no overdraft fees at all, could save you $60 to $140 per year. Over five years, that is $300 to $700 — real money that stays in your account instead of going to the bank.
Overdrafts versus declined transactions
When your account does not have enough money, your bank can either cover the transaction (creating an overdraft) or decline it. Both have costs, but they work differently.
A declined transaction stops the purchase from going through. The merchant tells you the card was declined, and you have to find another way to pay or leave the store without the item. Some banks charge a "declined transaction" or "insufficient funds" fee for this, usually $15 to $25 — less than an overdraft fee, but still a cost. The advantage is that you do not owe the bank money; you straightforward do not get what you were trying to buy.
An overdraft lets the transaction go through, but you now owe the bank the negative balance plus the overdraft fee. This is useful if you absolutely need to make the purchase and can pay the money back quickly. It is harmful if you overdraft repeatedly or if you do not notice the negative balance and let it sit for weeks.
You can ask your bank which option they use by default, and you can usually change it. Some people prefer declined transactions because they force you to stay within your means. Others prefer overdraft coverage because they do not want the embarrassment of a declined card. There is no right answer — it depends on your situation and how you manage money.
Frequently Asked Questions
Can I overdraft my account on purpose to get a short-term loan?
Technically yes, but it is an expensive way to borrow money. An overdraft fee of $35 on a $100 overdraft is a 35% fee for a few days of borrowing — far more expensive than a payday loan or credit card cash advance. If you need short-term money, a personal loan from a credit union or an advance from your employer is usually cheaper.
What happens if I do not pay back an overdraft?
Your bank will keep charging overdraft fees every day or every few days until your account goes positive. After several weeks, the bank may close your account and send the debt to a collection agency. This damages your credit and can make it harder to open a bank account at another bank for years. Pay back overdrafts as soon as you can.
Does an overdraft show up on my credit report?
An overdraft itself does not appear on your credit report. However, if you do not pay it back and the bank sends it to a collection agency, that collection account will show up on your credit report and harm your credit score. Paying back overdrafts quickly keeps this from happening.
Can I get overdraft fees refunded if I call my bank?
Many banks will reverse one or two overdraft fees if you ask, especially if you do not overdraft regularly and have been a customer for a while. There is no may provide, and some banks are stricter than others. It never hurts to ask, and the worst they can say is no.
Is overdraft protection the same as overdraft coverage?
No. Overdraft coverage is when the bank covers a transaction that would overdraft your account. Overdraft protection is when the bank transfers money from another account (usually savings) to cover the overdraft, and charges you a fee for the transfer. Overdraft protection is often cheaper per incident but can encourage repeated overdrafts.
