The minimum balance requirement depends on your bank and account type
Most banks do not require you to keep any money in a checking account. You can open one with a dollar or two, spend it all, and keep the account open with a zero balance. However, some banks do set a minimum balance requirement — a floor below which your account balance cannot drop without triggering a fee.
The amount varies widely. Some banks ask for $100, others for $500, $1,000, or more. A few banks have no minimum at all. The requirement depends on which bank you use, which specific account you open, and sometimes on whether you meet other conditions like setting up direct deposit or maintaining a linked savings account.
If you fall below the minimum, the bank typically charges a monthly fee — usually $10 to $25 — until your balance climbs back above the threshold. Some banks waive the fee if you bring the balance back up within a set number of days.
Key Takeaways
- Most checking accounts have no minimum balance requirement, but some banks charge a monthly fee if your balance drops below a stated amount.
- Minimum balance thresholds range from $100 to $2,500 or more, depending on the bank and account tier.
- You can often waive a minimum balance requirement by setting up direct deposit, maintaining a linked savings account, or meeting other conditions the bank specifies.
- The fee for dropping below the minimum is usually $10 to $25 per month, so choosing an account with no minimum can save money if you carry a low balance.
- Online banks and credit unions often have lower or no minimum balance requirements compared to large national banks.
How banks set and enforce minimum balance rules
Banks publish their minimum balance requirement in the account disclosure document you receive when you open the account. This document — sometimes called a "Truth in Savings" form or account agreement — lists the requirement, the fee for falling below it, and any ways to waive it.
The bank monitors your balance daily. If it drops below the minimum on any day during the month, most banks charge the fee at the end of that month. Some banks check only on the last day of the month, which gives you a small window to deposit money before the fee hits. Others check the average balance across the entire month — so if you dip below the minimum for a few days but recover, you may not be charged.
Read the fine print before opening an account, because the rules vary. A bank's website often does not spell out these details clearly, so call the bank directly or visit a branch and ask: "What is the minimum balance, when do you check it, and what fee do I pay if I fall below it?"
Ways to avoid or waive the minimum balance requirement
Many banks let you skip the minimum balance requirement if you meet certain conditions. The most common are setting up direct deposit (having your paycheck or benefits deposited automatically), maintaining a linked savings account with a minimum balance, or keeping a credit card with the same bank.
Some banks waive the requirement if you maintain a certain number of debit card transactions per month — often 10 or more. Others waive it if you sign up for paperless statements or online banking. A few banks offer a tiered system: meet one condition and the minimum drops from $1,000 to $500, or meet two conditions and it drops to zero.
Ask your bank which waivers apply to your account. If you do not meet any of them and the minimum is high, switching to a bank with no minimum requirement may be worth the effort.
Differences between bank types
Large national banks like Bank of America, Chase, and Wells Fargo typically have minimum balance requirements ranging from $500 to $2,500 for their standard checking accounts. They often waive the requirement if you set up direct deposit or link a savings account.
Regional and community banks vary widely. Some have minimums of $100 to $300, while others have none. Credit unions often have no minimum balance requirement or ask for only $25 to $100. Online banks — including Ally, Charles Schwab, and Discover — almost never have a minimum balance requirement, because they have lower overhead costs than brick-and-mortar branches.
If you carry a low balance and want to avoid fees, an online bank or credit union is usually the better choice. If you need access to physical branches and ATMs, a regional bank or credit union may offer a middle ground: lower minimums than national banks, but still some local presence.
What happens if you go below the minimum
The fee for falling below the minimum is not automatic in all cases. Some banks charge it immediately; others give you a grace period of 5 to 10 days to bring your balance back up. If you do, the fee is waived. Check your account agreement to see whether your bank offers a grace period.
If you are charged a fee and believe it was a mistake — for example, if a debit card transaction posted later than expected and temporarily dropped your balance — contact your bank. Many banks will reverse one or two fees per year if you ask, especially if you have been a customer for a long time.
Repeated fees add up quickly. If your bank charges $15 per month for falling below a $500 minimum, and you consistently carry a $200 balance, you will pay $180 per year in fees. Switching to an account with no minimum would save that money entirely.
Minimum balance versus overdraft protection
A minimum balance requirement is different from an overdraft. A minimum balance is the amount the bank wants you to keep in the account to avoid a fee. An overdraft occurs when you spend more than you have, and the bank covers the difference — usually charging an overdraft fee of $25 to $35 per transaction.
You can have an account with no minimum balance requirement and still incur overdraft fees if you spend more than your balance. Conversely, you can have a high minimum balance requirement and never overdraft, because you always have money in the account.
Some banks offer overdraft protection, which links your checking account to a savings account or credit line. If you overdraft, the bank automatically transfers money from the linked account to cover it, usually charging a smaller fee ($5 to $10) than a standard overdraft fee. This is different from a minimum balance requirement but can help you avoid overdraft fees if you keep a buffer in a linked savings account.
How to find an account with no minimum balance
Start by checking whether your current bank offers an account tier with no minimum. Many banks have multiple checking account options — a basic account with no minimum, a premium account with a high minimum, and accounts in between. You may already be may be able to access to switch to a no-minimum account without closing your current one.
If your bank does not offer a no-minimum option, or if the fees are high, compare online banks and credit unions. Most online banks publish their minimum balance requirement on the account details page of their website. Credit unions often have lower requirements than banks; search for a credit union in your area or look for one you can join based on your employer or community.
When comparing accounts, also look at other fees: monthly maintenance fees, ATM fees, overdraft fees, and fees for using out-of-network ATMs. A bank with no minimum balance but high ATM fees may cost more than a bank with a low minimum and free ATM access.
Frequently Asked Questions
Can I keep a checking account open with zero dollars in it?
Yes, most banks allow you to keep an account open with a zero balance indefinitely. However, some banks close accounts that remain inactive or at zero balance for 12 months or longer. Check your account agreement or call your bank to confirm their policy on inactive accounts.
Does a minimum balance requirement apply to savings accounts too?
Yes, many savings accounts have minimum balance requirements, and the rules are similar to checking accounts. Some banks charge a monthly fee if your savings balance falls below the minimum. Others require a minimum deposit to open the account but do not charge a fee if the balance drops later. Read the savings account disclosure before opening one.
What if I cannot meet the minimum balance right now?
Open an account with no minimum requirement instead. Online banks, credit unions, and some regional banks offer checking accounts with zero minimum. You can always switch to a different bank later if your financial situation changes and you want access to more features or branches.
Do joint checking accounts have different minimum balance rules?
The minimum balance requirement is the same for joint accounts as for individual accounts — it applies to the total balance in the account, not to each person's share. Both account holders are responsible for maintaining the minimum, and both can be affected by fees if the balance drops below it.
Can I negotiate a lower minimum balance with my bank?
Rarely, but it is worth asking if you have been a customer for years or if you maintain other accounts or services with the bank. Some banks will lower the minimum for loyal customers or if you agree to set up direct deposit. The worst they can say is no, and the best outcome is a lower fee or waived requirement.
