Bank of America doesn't set a fixed overdraft limit you can see in advance

Bank of America doesn't tell you "your overdraft limit is $500" or any other number. Instead, the bank decides case by case whether to cover a transaction that would otherwise bounce. That decision depends on your account history, how long you've banked there, your balance patterns, and whether you've overdrawn before.

This means you could overdraft by $50 one day and have a $200 transaction declined the next day, even if your account looks similar. The bank is making a real-time judgment call, not following a preset rule.

What you can control is whether you pay overdraft fees when this happens. Bank of America charges $35 per overdraft transaction, and you can turn overdraft protection on or off in your account settings.

Key Takeaways

  • Bank of America does not publish overdraft limits; the bank decides whether to cover each transaction individually based on your account history.
  • If the bank covers a transaction that overdraws your account, you pay a $35 fee per overdraft, and the fee applies even if the overdraft is only a few dollars.
  • You can turn overdraft protection on or off through your online account or mobile app, which controls whether the bank will cover overdrafts or decline transactions instead.
  • Overdraft protection does not prevent fees—it only determines whether transactions go through or bounce; you still pay $35 if the bank covers the overdraft.
  • Bank of America also offers overdraft lines of credit through its checking accounts, which work differently and may have lower fees, though not all accounts include this option.

What happens when you overdraft at Bank of America

When you attempt a transaction that would take your balance below zero, Bank of America first checks whether you have overdraft protection turned on. If you do, the bank may cover the transaction and charge you $35. Your account balance goes negative, and you owe that money back when ready.

If you have overdraft protection turned off, the transaction is declined at the point of sale. No fee is charged because the bank did not cover the overdraft. This is the safest option if you want to avoid fees, but it means your debit card or check may be rejected in front of a cashier.

The $35 fee applies once per transaction, not once per day. If you make five overdraft transactions in one day, you pay $35 five times. Bank of America does cap overdraft fees at four per day for debit card transactions, but not for checks or ACH transfers.

How to turn overdraft protection on or off

You control overdraft protection through your Bank of America online account or the mobile app. Log in, go to Account Settings, find Overdraft Protection, and toggle it on or off. The change takes effect when ready.

Turning it off means transactions will decline rather than overdraft. Turning it on means the bank may cover overdrafts, but you will pay the $35 fee. Neither option prevents fees entirely—one prevents them by declining transactions, the other charges them when the bank covers you.

Some Bank of America accounts come with an overdraft line of credit, which is different from overdraft protection. This is a small credit line (often $100 to $500) that you can draw on if you overdraft. Interest charges explore to the borrowed amount, but there is no flat $35 fee. You can ask your bank whether your account includes this option.

Why Bank of America doesn't publish a limit

Banks keep overdraft decisions flexible because they want to avoid declining transactions for good customers while protecting themselves against chronic overdrafters. A customer with a five-year history and a healthy average balance is more likely to get an overdraft covered than someone who opened an account last month.

This flexibility also protects the bank. If Bank of America published a $500 overdraft limit, it would be legally promising to cover any overdraft up to that amount. Instead, by keeping the limit invisible, the bank can refuse to cover an overdraft if it suspects fraud or if you have a pattern of overdrafting without repaying.

The downside for you is that you cannot plan around a known limit. You have to assume that any transaction might be declined or might trigger a fee.

Strategies to avoid overdraft fees

The most direct strategy is to turn off overdraft protection entirely. This means you will never pay a $35 overdraft fee because transactions will straightforward decline. You may face embarrassment or inconvenience when a card is declined, but you will not lose money to fees.

If you want the safety net of overdraft protection, keep a small buffer in your account—$100 or $200—that you do not spend. This cushion absorbs small mistakes without triggering an overdraft. Check your balance before large purchases or before payday if your income is irregular.

Set up account alerts through the Bank of America app. You can receive a notification when your balance drops below a certain amount, giving you time to transfer money in or adjust your spending before an overdraft happens.

Overdraft protection versus overdraft lines of credit

Bank of America offers two different products, and they work in opposite ways. Overdraft protection is what most checking accounts have by default. When you overdraft with protection on, the bank covers the transaction and charges you $35. You owe the full overdraft amount when ready.

Overdraft lines of credit are small credit lines (typically $100 to $500) attached to some checking accounts. If you overdraft, you borrow from this line instead of the bank covering the transaction from its own funds. You pay interest on the borrowed amount, usually calculated daily, but there is no flat $35 fee. The interest rate varies by account type.

An overdraft line of credit can be cheaper if you overdraft by a small amount and repay it quickly. For example, borrowing $100 for one week might cost $1 in interest, versus $35 for a single overdraft protection fee. But if you overdraft regularly or borrow for a long time, the interest adds up. Ask your Bank of America branch whether your account includes an overdraft line of credit and what the interest rate is.

What to do if you overdraft repeatedly

If you find yourself overdrafting multiple times a month, the fees are a sign that your spending is outpacing your income or that you are not tracking your balance carefully. Paying $35 per overdraft is expensive and unsustainable.

Start by turning off overdraft protection to stop the fees when ready. Then look at your spending: use your bank's transaction history to see where money is going. Many people overdraft because of small recurring charges they forgot about—subscriptions, apps, automatic payments—that add up.

If your income is irregular (you work freelance, gig work, or commission-based jobs), overdrafting is more likely because you cannot predict when money arrives. In that case, try to build a larger buffer in your account during high-income months so you have cushion during low months. Some people also move money to a separate savings account to prevent themselves from spending it.

Frequently Asked Questions

Can Bank of America refuse to cover an overdraft even if I have overdraft protection on?

Yes. Overdraft protection means the bank may cover overdrafts, not that it will. The bank can decline a transaction or refuse to cover an overdraft if it suspects fraud, if you have a history of not repaying overdrafts, or if the transaction is unusually large. Having the feature turned on does not may provide coverage.

How long do I have to repay an overdraft?

Bank of America expects you to repay when ready, though the bank will not close your account or take legal action if you take a few days. However, if your account stays negative for an extended period (typically 30 days or more), the bank may close the account and report it to ChexSystems, a banking history database that makes it harder to open accounts elsewhere.

Does overdraft protection affect my credit score?

Overdrafting itself does not show up on your credit report because it is not a loan. However, if you overdraft and do not repay, and Bank of America closes your account and sends it to collections, that will damage your credit. Staying out of overdraft is the safest approach.

Can I set my own overdraft limit?

No. Bank of America does not let you set a limit. You can only turn overdraft protection on or off. If you want more control, you can turn it off and rely on declined transactions, or you can ask about an overdraft line of credit, which has a set limit that the bank assigns based on your account.

What is the difference between a debit card overdraft and a check overdraft?

Bank of America caps debit card overdraft fees at four per day, but checks and ACH transfers (automatic payments) have no daily cap. This means you could write five checks that all overdraft your account and pay $35 five times in one day. Debit cards are slightly more protected, but both can be expensive.
