What happens when you overdraft your account

An overdraft occurs when you spend more money than you have in your account, and your bank covers the difference. The bank is lending you that money temporarily. You now owe the bank the negative balance plus an overdraft fee, which is a charge for the service of covering the shortfall. The fee is separate from any interest the bank may charge on the borrowed amount.

Most banks charge between $25 and $35 per overdraft transaction, though some charge more. The fee hits your account immediately or within one to two business days. If you do not deposit money to cover the overdraft quickly, you may face additional fees — some banks charge a daily fee for each day your account stays negative, or a second overdraft fee if another transaction posts while you are still in the red.

Your bank does not have to cover the overdraft. Whether it does depends on your account type, your history with the bank, and the bank's own overdraft policy. Some banks automatically cover overdrafts for debit card purchases and ATM withdrawals; others do not. Some require you to opt in to overdraft protection first.

Key Takeaways

  • An overdraft is a loan from your bank that covers a transaction when your balance is too low, followed by an overdraft fee of $25 to $35 or more.
  • Your bank decides whether to cover an overdraft — it is not required to do so, and the decision depends on your account agreement and history.
  • Overdraft fees can stack if multiple transactions post while your account is negative, or if your account stays negative for several days.
  • Opting out of overdraft protection stops the bank from covering overdrafts, which prevents fees but may cause transactions to be declined instead.
  • Recovering from an overdraft means depositing enough to cover both the negative balance and all fees before additional charges accrue.

How overdraft protection works and whether you have it

Overdraft protection is your bank's agreement to cover overdrafts on your account. Federal law requires banks to ask your permission before they start covering overdrafts on debit card purchases and ATM withdrawals — this is called opting in. However, banks do cover overdrafts on checks and automatic bill payments without requiring opt-in permission.

If you have not opted in, your debit card or ATM withdrawal will simply be declined when your balance is too low. You will not overdraft, and you will not pay a fee. If you have opted in, the transaction will go through, and you will owe the overdraft fee.

You can find your overdraft protection status by logging into your online banking, calling your bank's customer service line, or visiting a branch. Your account agreement or disclosures should also state whether overdraft protection is active. If you want to turn it off, contact your bank and request to opt out of overdraft protection.

When multiple overdraft fees stack up

A single transaction can trigger multiple fees if your account stays negative and more transactions post. Here is how it typically works: you overdraft on Monday with a $35 fee. On Tuesday, before you deposit money, another transaction posts — your bank may charge a second $35 overdraft fee for that transaction. If your account is still negative on Wednesday, some banks charge a daily fee (often $5 to $10 per day) for each day the account remains below zero.

The fees compound quickly. An initial $50 overdraft can become $100 or more in fees within a few days if multiple transactions post or if daily fees apply. This is why recovering from an overdraft as soon as possible matters — every day you wait, the total amount you owe grows.

Some banks cap the number of overdraft fees you can incur per day or per month, but not all do. Check your account agreement or call your bank to understand the fee structure for your specific account.

How to recover from an overdraft

To stop the overdraft and prevent additional fees, deposit enough money to cover both the negative balance and all overdraft fees that have posted. For example, if your balance is negative $50 and you have been charged $35 in overdraft fees, you need to deposit at least $85.

You can deposit money by direct deposit, transfer from another account, mobile check deposit, ATM deposit, or in-person at a branch. Direct deposit and transfers are fastest — they usually post within one business day. Mobile check deposits and ATM deposits may take one to two business days. Once the deposit posts and your balance is positive, no more overdraft fees will accrue.

If you cannot deposit the full amount immediately, deposit what you can. Your account will still be negative, and daily fees may continue, but at least you are moving toward recovery. Contact your bank and ask whether they will waive or reduce the overdraft fees — some banks do this for customers with good history, especially if the overdraft was a one-time mistake.

The difference between overdraft protection and overdraft fees

Overdraft protection and overdraft fees are related but separate. Overdraft protection is the bank's decision to cover a transaction when your balance is low. Overdraft fees are the charges you pay for that service. You cannot have one without the other — if the bank covers your overdraft, you pay the fee.

Some banks offer overdraft lines of credit as an alternative. This is a small loan account linked to your checking account. If you overdraft, the bank automatically transfers money from the line of credit to cover it. You pay interest on the borrowed amount, not a flat overdraft fee. Interest rates on overdraft lines of credit vary by bank and your creditworthiness, but they are often lower than the cost of repeated overdraft fees.

Other banks offer savings account transfers as overdraft protection. If you overdraft your checking account, the bank automatically transfers money from your linked savings account to cover it. You may pay a small transfer fee ($1 to $3), but this is usually much cheaper than an overdraft fee.

Why opting out of overdraft protection might make sense

If you opt out of overdraft protection, your debit card and ATM withdrawals will be declined when your balance is too low. You will not overdraft, and you will not pay an overdraft fee. The transaction simply will not go through.

This forces you to spend only what you have, which prevents debt. However, it also means you cannot use your debit card or ATM if your balance is low, even in an emergency. A declined transaction can be embarrassing and inconvenient, especially if you are at a checkout or an ATM away from home.

Checks and automatic bill payments will still overdraft even if you opt out of debit card overdraft protection — opting out does not affect those. If you want to prevent overdrafts entirely, you need to monitor your balance carefully and make sure all transactions (including checks and automatic payments) do not exceed what you have.

How to avoid overdrafts in the first place

The simplest way to avoid overdrafts is to keep a buffer in your account — money you do not spend. A buffer of $100 to $200 catches most accidental overdrafts. You can build a buffer by depositing a small amount each paycheck and treating it as untouchable.

Set up balance alerts through your bank's app or website. Most banks let you receive a text or email when your balance drops below a certain amount (often $50 or $100). An alert gives you time to deposit money or adjust your spending before you overdraft.

Track your spending and know what transactions are pending. Debit card transactions post immediately or within one business day, but checks and automatic bill payments can take several days. If you know a large check is coming, do not spend money assuming it has not posted yet.

If you receive regular paychecks, time your spending around your pay dates. Do not spend money from a paycheck before it arrives. If you have automatic bill payments, schedule them for a few days after your paycheck posts, so you know the money is there.

Frequently Asked Questions

Can a bank refuse to cover an overdraft?

Yes. Banks are not required to cover overdrafts. If you have not opted in to overdraft protection, or if your account type does not include it, the bank will decline the transaction instead. Even if you have opted in, a bank can refuse to cover an overdraft if you have a history of overdrafting or if the transaction is unusually large.

How long do I have to pay back an overdraft?

You do not have a formal repayment period. The overdraft is covered as soon as you deposit money to bring your balance positive. However, if you do not deposit money, your account stays negative and daily fees may continue to accrue. Some banks may close your account or report you to a checking account registry if you remain overdrawn for an extended period (often 30 to 60 days).

Will an overdraft hurt my credit score?

An overdraft itself does not appear on your credit report and does not affect your credit score. However, if your account goes to collections because you do not pay it back, that can damage your credit. Additionally, some banks report unpaid overdrafts to ChexSystems, a checking account registry that other banks use to decide whether to open accounts for you.

Can I dispute an overdraft fee?

Yes, you can contact your bank and ask them to waive or reduce the fee. Banks sometimes do this for customers with good history or if the overdraft was caused by a bank error. There is no may provide they will agree, but it costs nothing to ask. If the bank refuses, you can file a complaint with the Consumer Financial Protection Bureau or your state's banking regulator.

What is the difference between an overdraft and a returned check?

An overdraft means the bank covered the transaction and you owe them the money plus a fee. A returned check (or bounced check) means the bank refused to cover it — the check was not processed, and the recipient did not receive the money. You still pay a fee for the returned check, and the recipient may charge you an additional fee for the bounced check.
