Your bank will either reject the transaction or pay it and charge you a fee

When you try to spend more money than you have in your checking account, one of two things happens. Your bank either declines the transaction at the point of sale—the card reader says no, the check bounces, the transfer fails—or the bank pays the transaction anyway and your account balance goes negative. If the bank pays it, you now owe the bank money, and they will charge you an overdraft fee, usually between $25 and $35 per transaction. Some banks charge multiple fees in a single day if several transactions post while your account is negative.

Which outcome you get depends on your bank's overdraft policy and the type of transaction. Debit card purchases and ATM withdrawals are more likely to be declined. Checks, automatic bill payments, and ACH transfers are more likely to be paid even if you lack the funds, triggering overdraft fees. Your bank's overdraft policy is in your account agreement; most banks allow you to opt out of overdraft coverage for debit transactions, which means those will simply be declined instead.

Key Takeaways

  • A single overdraft fee is typically $25 to $35, and multiple transactions can trigger multiple fees on the same day.
  • Checks and automatic payments are more likely to overdraw your account than debit card purchases, which banks often decline instead.
  • You can usually opt out of overdraft coverage for debit transactions, forcing the bank to decline them rather than charge you a fee.
  • Your bank may reverse one overdraft fee per year if you ask, but this is a courtesy, not a right, and depends on your account history.
  • If your account stays negative for more than 30 days, the bank may close it and report you to ChexSystems, making it harder to open accounts elsewhere.

How overdraft fees stack up in a single day

Overdraft fees compound quickly because banks process transactions in an order that maximizes fees, not the order you made them. Your bank typically posts larger transactions first, then smaller ones, even if you made the small purchase before the large one. This means if you spend $15, then $200, then $30, the bank might post the $200 first. That triggers one overdraft fee. Then the $30 posts and triggers another. Then the $15 posts and triggers a third. You end up paying $75 to $105 in fees for transactions that total $245.

Some banks cap the number of overdraft fees per day—often at three or four—but not all do. A few banks charge a daily overdraft fee (around $5 to $10) for each day your account is negative, on top of per-transaction fees. Check your account agreement or call your bank to find out their specific policy. The fee structure is not always obvious from the website.

What happens to your account while it is negative

Once your account goes negative, the bank treats it as a debt you owe them. Interest does not accrue on overdraft balances the way it does on credit cards—the bank is not charging you interest, just the flat overdraft fee per transaction. However, your account will remain negative until you deposit money to cover both the original overspending and the fees themselves.

While your account is negative, new transactions may still be processed and trigger additional overdraft fees. Automatic payments like insurance premiums or loan payments will continue to post and may overdraw you further. Deposits you make will first go toward covering the negative balance before you can spend that money. If you deposit $100 and your account is $75 negative, you now have $25 available to spend.

When your bank may close your account

If your account stays negative for 30 days or longer without you bringing it current, your bank may close the account. Some banks close accounts sooner; others give you 60 days. Once closed, the bank sends your account to a collections agency or pursues the debt themselves. You will owe not just the overdraft fees but also the original negative balance.

A closed account for overdraft also gets reported to ChexSystems, a banking history database. This report stays on file for five years and makes it very difficult to open a checking account at another bank during that time. Many banks check ChexSystems before opening new accounts and will deny you if you have an unpaid overdraft closure on record. Some banks specialize in second-chance accounts for people with ChexSystems records, but they often charge higher fees and offer fewer features.

How to recover from an overdrawn account

The fastest way out is to deposit enough money to cover the negative balance plus all overdraft fees. Once the account is positive again, the overdraft fees stop accruing. Call your bank and ask whether they will reverse one overdraft fee as a courtesy. Many banks will reverse one fee per year if you have a clean account history otherwise, though this is not may provide and depends on the bank and your relationship with them. It costs nothing to ask.

If your account has been closed due to overdraft, contact the bank's collections department and ask what it will take to settle the debt. Some banks will negotiate a payment plan or accept a lump sum that is less than the full amount owed, especially if the account has been closed for several months. Get any settlement agreement in writing before you pay. Once you have paid, ask the bank to remove the ChexSystems report; some will do this, though they are not required to.

Opting out of overdraft coverage to avoid fees

Federal law allows you to opt out of overdraft coverage for debit card purchases and ATM withdrawals. If you opt out, these transactions will simply be declined instead of triggering overdraft fees. You cannot opt out of overdraft coverage for checks or automatic bill payments—those will still overdraw your account if funds are not available.

To opt out, contact your bank directly. Some banks let you do this online through your account settings; others require a phone call or a visit to a branch. Ask for written confirmation of your opt-out status. Opting out does not prevent overdrafts entirely—checks and automatic payments can still overdraw you—but it stops the most common source of overdraft fees for most people.

The difference between overdraft and insufficient funds

Overdraft means the bank paid a transaction even though you did not have enough money, and your account went negative. Insufficient funds means you did not have enough money and the bank declined the transaction. Insufficient funds does not cost you a fee; the transaction simply does not go through. Overdraft costs you a fee because the bank covered the shortfall.

When you see "NSF" (non-sufficient funds) on your statement, it usually means a transaction was declined due to insufficient funds. Some banks charge a small NSF fee ($5 to $15) for the declined transaction itself, separate from overdraft fees. Check your account agreement to see whether your bank charges NSF fees.

Frequently Asked Questions

Can a bank charge me an overdraft fee if I did not authorize the overdraft?

Yes. Overdraft fees are charged automatically when a transaction posts and your account goes negative, regardless of whether you intended it. You can opt out of overdraft coverage for debit transactions to prevent this, but you cannot opt out for checks or automatic payments. If you believe a fee was charged in error, contact your bank to request a reversal.

How long do I have to pay back an overdrawn account?

There is no legal deadline, but your bank can close your account if it stays negative for 30 to 60 days. Once closed, the bank may send it to collections, and you will owe the full amount plus any collection costs. The sooner you deposit money to cover the negative balance, the sooner the account returns to normal.

Will an overdrawn account hurt my credit score?

An overdrawn checking account does not directly appear on your credit report and does not hurt your credit score. However, if the bank closes the account and sends it to collections, the collection account will appear on your credit report and damage your score. A ChexSystems report also makes it harder to open new bank accounts.

Can I dispute an overdraft fee?

You can ask your bank to reverse the fee, but you cannot formally dispute it the way you would dispute a fraudulent charge. Banks treat overdraft fees as contractual charges, not errors. Your best option is to call and ask for a courtesy reversal, especially if you have a good account history or if the overdraft was caused by a bank error.

What if my paycheck deposits but my account is still negative?

The deposit will first cover the negative balance and overdraft fees before you can spend any of it. If your paycheck is $1,500 and your account is $200 negative with $75 in fees, the deposit brings your balance to $1,225 available to spend. The bank applies deposits to negative balances automatically.
