Most banks do require a minimum balance, but the amount and what happens if you fall short varies widely
Whether your checking account has a minimum balance requirement depends entirely on which bank you use and which account type you open. Some banks require $0 minimum. Others require $500, $1,000, or more. If you fall below the minimum, the bank typically charges a monthly fee—usually $10 to $25—though a few banks will simply close your account instead.
The minimum exists because banks use your balance to lend money to other customers. A higher balance in your account means more money the bank can put to work. In exchange for keeping that money there, the bank waives or reduces fees. If you can't maintain the minimum, you pay the difference as a fee.
The key is knowing your bank's specific rule before you open the account. Many banks advertise "no minimum balance" as a selling point. Others bury the requirement in the account terms. Some waive the minimum if you set up direct deposit or maintain a linked savings account.
Key Takeaways
- Minimum balance requirements range from $0 to $2,500 or higher depending on the bank and account tier.
- If your balance drops below the minimum, the bank charges a monthly maintenance fee, typically $10 to $25.
- Some banks waive the minimum if you receive direct deposit, maintain a linked savings account, or use the debit card a certain number of times per month.
- Online banks and credit unions are more likely to offer no-minimum accounts than traditional brick-and-mortar banks.
- The minimum applies to your available balance, not pending transactions, so a check you wrote but hasn't cleared yet does not count against it.
How banks define and measure your minimum balance
The minimum balance is the lowest amount of money your bank requires you to keep in the account at all times. Most banks measure this as your daily balance—the amount in the account at the end of each business day. If your balance dips below the minimum on even one day, many banks charge the fee for that entire month.
Some banks use a different measure: average daily balance over the statement period. This is more forgiving because a single low day doesn't trigger the fee if your balance recovers. Ask your bank which method it uses before you open the account, because the difference can cost you $10 to $25 per month.
The balance that counts is your available balance, not your account balance. Available balance excludes pending transactions—checks you wrote that haven't cleared yet, debit card charges that are processing, or transfers you initiated. A pending charge does not cause you to fall below the minimum, even if it would if it posted.
Common minimum balance amounts and what triggers them
Banks typically tier their checking accounts by minimum balance. A basic account might have no minimum or a $100 minimum. A "premium" or "preferred" account might require $500 or $1,000. A high-yield or wealth-management account might require $2,500 or $10,000.
The fee for falling below the minimum is usually a flat monthly charge of $10 to $25. Some banks charge a percentage of the shortfall instead—for example, $0.25 per day for every dollar below the minimum. Over a month, that can add up faster than a flat fee.
A few banks do not charge a fee but will close your account if the balance stays below the minimum for 30 to 90 days. This is less common but does happen, especially at smaller regional banks. Check your account agreement to see whether your bank charges a fee or closes the account.
Ways to waive or avoid the minimum balance requirement
Many banks will waive the minimum balance requirement if you meet one or more conditions. The most common waiver is direct deposit—having your paycheck or government benefit deposited directly into the account. This signals to the bank that you are using the account regularly and have steady income.
Other common waivers include maintaining a linked savings account with a minimum balance, using your debit card a certain number of times per month (often 10 or more), or keeping a credit card with the same bank. Some banks waive the minimum if you maintain a certain total balance across all your accounts with them, not just the checking account.
Online banks and credit unions are significantly more likely to offer no-minimum checking accounts than traditional banks. If you are struggling to maintain a minimum at your current bank, switching to an online bank or credit union may be simpler than trying to meet your bank's waiver conditions.
What happens when your balance falls below the minimum
The most common outcome is a monthly maintenance fee. The bank charges this fee automatically on a set day each month—often the last day of the statement period. The fee posts to your account, which lowers your balance further. If you are already close to zero, one fee can push you into overdraft territory and trigger overdraft fees on top of the minimum balance fee.
Some banks will send you a notice before charging the fee, giving you a few days to deposit money and bring your balance back up. Others charge first and notify you after. Read your account agreement or call your bank to find out which approach yours uses.
If your balance stays below the minimum for an extended period—usually 30 to 90 days—the bank may close your account without warning. When this happens, any remaining balance is mailed to you as a check, and the account is reported to ChexSystems, a banking history database. This can make it harder to open a new account elsewhere for several years.
Minimum balance requirements at different types of banks
Traditional brick-and-mortar banks (Chase, Bank of America, Wells Fargo) typically require a minimum balance of $100 to $500 for basic checking, with higher tiers requiring $1,000 or more. They often waive the minimum for direct deposit or linked savings.
Online banks (Ally, Charles Schwab, Discover) almost always offer checking accounts with no minimum balance requirement. Because they have no physical branches, their operating costs are lower, and they can afford to waive the minimum as a competitive advantage.
Credit unions vary widely, but many offer no-minimum checking accounts to members. Some require a small savings account balance ($25 to $100) to maintain membership, but this is different from a checking account minimum. Ask your credit union about its specific requirements.
Prepaid card companies and mobile banking apps typically have no minimum balance requirement because they are not traditional banks and do not lend your balance to other customers.
How to find out your bank's minimum balance requirement
If you already have a checking account, the easiest way to find out is to log into your online banking portal and look for the account details or terms. Most banks list the minimum balance requirement in the account summary. You can also call your bank's customer service line or visit a branch and ask directly.
If you are shopping for a new account, check the bank's website for the account disclosure document, often called a "Truth in Savings" statement or account agreement. This document lists the minimum balance, the fee for falling below it, and any waivers. Do not rely on marketing materials alone—they often highlight the no-minimum option without mentioning that it applies only to certain account types.
When comparing banks, write down the minimum balance, the monthly fee, and the waivers for each account type you are considering. Then calculate which option costs you the least based on your typical balance. If you usually keep $300 in checking, a bank with a $500 minimum and a $15 fee is more expensive than a no-minimum bank, even if the no-minimum bank charges a small monthly fee.
Frequently Asked Questions
Does a pending deposit count toward my minimum balance?
No. Only your available balance counts. A deposit you initiated but that has not yet posted does not count toward the minimum. However, once the deposit clears and posts to your account, it does count. If you are trying to avoid a fee, make sure the deposit will clear before the day the bank measures your balance.
What if I fall below the minimum for just one day?
If your bank uses daily balance measurement, one day below the minimum can trigger the monthly fee. If your bank uses average daily balance, a single low day usually does not cause a fee as long as your balance recovers. Call your bank to confirm which method it uses, because this can save you $10 to $25 per month.
Can I have a checking account with no minimum balance?
Yes. Many online banks, credit unions, and some traditional banks offer checking accounts with no minimum balance requirement. You may need to meet other conditions, such as setting up direct deposit or maintaining a linked savings account, but true no-minimum accounts do exist.
If I close my account, do I lose money?
No. When you close a checking account, you receive whatever balance remains in the account. The bank does not keep the money. However, if your account is closed due to staying below the minimum for too long, the bank will mail your remaining balance to you as a check, which can take several weeks.
Does my savings account minimum balance affect my checking account?
Not directly. Your checking and savings accounts are separate. However, some banks waive the checking account minimum if you maintain a minimum balance in a linked savings account. Check your account agreement to see if this waiver applies to you.
