Most checking accounts do not require you to keep a minimum balance, but some do—and the amount varies widely by bank
Whether a checking account needs a minimum balance depends entirely on the bank and the specific account type you choose. Some banks have no minimum at all. Others require anywhere from $100 to $2,500 or more to avoid monthly fees. A few banks waive the minimum if you meet other conditions, like setting up direct deposit or maintaining a linked savings account.
The minimum balance requirement is not a legal rule—it is a business decision each bank makes. You will find the requirement listed in the account's fee schedule, which the bank must provide before you open the account. If you do not meet the minimum, the bank typically charges a monthly maintenance fee, usually between $5 and $15.
Key Takeaways
- No federal law requires checking accounts to have a minimum balance; banks set their own rules.
- Minimum balance requirements range from zero to several thousand dollars depending on the bank and account tier.
- If you fall below the minimum, the bank charges a monthly fee rather than closing your account.
- Online banks and credit unions often have lower or no minimum balance requirements than traditional brick-and-mortar banks.
- Some banks waive the minimum if you meet alternative conditions like receiving direct deposit or maintaining a certain savings balance.
How banks calculate and enforce minimum balance requirements
Banks measure your balance in different ways. Some look at your balance on a specific day each month—usually the last day of the statement period. Others calculate an average balance across the entire month. A few require you to maintain the minimum at all times, meaning even a single day below the threshold can trigger a fee.
When you fall short, the bank does not close your account. Instead, it deducts the monthly maintenance fee from your balance. If your account is already low, this fee can push you into overdraft territory, which then triggers overdraft fees on top of the maintenance fee. This is why understanding the exact requirement matters: a $500 minimum you miss by $50 can cost you $10 to $15 in fees, plus potential overdraft charges if the fee itself overdraws you.
The fee schedule you receive before opening the account will specify exactly how the bank measures the balance. Read this document carefully—it is the contract that governs the account, and it will tell you the precise rule for your specific account type.
Minimum balance requirements by bank type
Traditional banks (Chase, Bank of America, Wells Fargo, Citibank) typically require $500 to $2,500 for their standard checking accounts, though they often offer lower-tier accounts with no minimum or waived minimums for direct deposit. Premium or high-yield checking accounts at these banks may require $10,000 or more.
Online banks (Ally, Charles Schwab, Discover, Chime) usually have no minimum balance requirement at all. Because they have no physical branches, their operating costs are lower, and they can afford to waive this fee entirely. This is one of the main reasons people switch to online banking.
Credit unions vary widely. Some have no minimum; others require $25 to $500. Credit unions are member-owned, so their fee structures differ from bank to bank. You will need to check with your specific credit union.
Prepaid debit card accounts sometimes have no minimum balance requirement because they are not technically checking accounts—you load money onto them rather than maintaining a bank balance. However, some prepaid cards charge monthly fees regardless of balance.
Ways to avoid or waive minimum balance fees
If your bank does require a minimum but you cannot maintain it, look for waiver conditions. Many banks will drop the requirement if you set up direct deposit—meaning your paycheck or government benefits deposit automatically each month. Others waive it if you maintain a linked savings account with a certain balance, or if you use the debit card a set number of times per month.
Some banks offer tiered accounts: a basic account with no minimum and no perks, and a premium account with a higher minimum but better interest rates or fee waivers. If you cannot meet the minimum on the premium account, downgrading to the basic account costs nothing and removes the fee entirely.
If you are with a traditional bank and consistently cannot meet the minimum, switching to an online bank or credit union is often simpler than trying to meet waiver conditions. The switching process takes a few days—you provide your new bank with your old account number, and they handle the transfer of recurring deposits and payments.
What happens if you go below the minimum
The bank will not freeze your account or prevent you from using it. You can still make deposits, withdrawals, and transfers. What happens is a monthly fee appears on your statement, usually labeled "maintenance fee" or "account fee." This fee is deducted automatically from your balance.
If your balance is already very low when the fee hits, the fee itself can overdraw your account. For example, if you have $8 and the bank charges a $12 maintenance fee, your balance becomes -$4. At that point, overdraft fees kick in—typically $25 to $35 per overdraft transaction. A single missed minimum balance requirement can cascade into multiple fees.
You can dispute a fee if you believe it was charged in error, but you must contact the bank within a specific window—usually 30 to 60 days. The bank will review the fee and may reverse it if you have a good history or if the charge was genuinely a mistake. However, if you straightforward fell below the minimum, the fee is legitimate and will not be reversed.
Minimum balance requirements versus other account costs
Minimum balance is just one fee structure. Some accounts have no minimum but charge per-transaction fees ($0.25 to $1 per debit card use, for example). Others have no minimum and no transaction fees but pay zero interest on your balance. A few accounts have a minimum but pay interest, which can offset the cost of maintaining the balance.
| Account Type | Typical Minimum | Monthly Fee (if below minimum) | Other Costs |
|---|---|---|---|
| Traditional bank standard checking | $500–$2,500 | $10–$15 | Overdraft fees, ATM fees outside network |
| Online bank checking | $0 | $0 | None (usually) |
| Credit union checking | $0–$500 | $5–$12 | Varies by union |
| High-yield checking (traditional bank) | $10,000+ | $15–$25 | Offset by interest earned |
When comparing accounts, look at the total cost, not just the minimum. An account with a $1,000 minimum but zero other fees might be cheaper than an account with no minimum but $1 per transaction. Calculate based on how you actually use the account: if you make 50 debit card transactions per month, transaction fees add up quickly.
How to find the minimum balance requirement before opening an account
The fee schedule is the official document. Banks are required to provide it before you open the account, either in person, by mail, or online. On a bank's website, look for "Checking Account Terms," "Fee Schedule," "Account Details," or "Disclosures." The minimum balance requirement will be listed clearly, along with how it is measured and what happens if you miss it.
Do not rely on the marketing language on the main account page. A bank might advertise "no monthly fees" but still charge a maintenance fee if you fall below the minimum. The fee schedule is the binding document—that is where the actual rules are.
If you cannot find the fee schedule online, call the bank or visit a branch and ask for it. You have the right to see it before committing to the account. Many banks will also email it to you or let you read it as a PDF.
Frequently Asked Questions
Can a bank close my account if I do not meet the minimum balance?
No. Banks charge a fee if you fall below the minimum, but they do not close the account. However, if you have repeated overdrafts or suspicious activity, the bank can close the account for other reasons. Falling below the minimum alone will not trigger closure.
If I have direct deposit, do I still need to maintain a minimum balance?
Many banks waive the minimum balance requirement if you have direct deposit set up, but not all. Check your account's fee schedule or call the bank to confirm. Some banks require the direct deposit to be a certain amount or frequency to may have access to for the waiver.
What is the difference between a minimum balance and an average balance requirement?
A minimum balance is the lowest amount you can have on any given day. An average balance is calculated across the entire month—so if you have $1,000 one day and $100 the next, your average might be $550. Average balance requirements are slightly easier to meet because a single low day does not trigger a fee.
Do online banks really have no minimum balance requirements?
Most major online banks have no minimum, but not all. Ally, Charles Schwab, and Chime do not require a minimum. However, some online banks or fintech accounts do charge monthly fees or require a minimum. Always check the fee schedule before opening the account.
If I close my account while below the minimum, do I owe the bank the fee?
No. Once you close the account, the bank cannot charge future fees. However, if the fee was already charged before you closed the account, you still owe it. The bank may deduct it from your remaining balance when you withdraw your funds.
