The minimum balance is the lowest amount your bank requires you to keep in the account to avoid a monthly fee
Most savings accounts set a minimum balance requirement — typically between $100 and $2,500, though some banks have none. If your balance drops below that threshold on any day of the month (or on the last day, depending on the bank's rule), you pay a monthly maintenance fee, usually $5 to $15. Some banks waive the fee if you meet other conditions instead: setting up direct deposit, maintaining a linked checking account, or keeping a certain amount in other products with that bank.
The requirement exists because banks use customer deposits to lend money out. A low-balance account costs them more to maintain than it brings in. The minimum protects their margin; the fee is their way of charging you directly if you don't meet it.
Not all banks enforce this the same way. Some check your balance daily and charge a fee if you dip below the minimum even once. Others check only on the last day of the month. A few check your average balance over the entire month. Read your account agreement or call your bank to know which rule applies to you.
Key Takeaways
- Minimum balance requirements range from $0 to $2,500 depending on the bank and account type; dropping below it triggers a monthly fee.
- Banks check your balance on different schedules — some daily, some only on the last day of the month — so know your bank's specific rule.
- Many banks waive the minimum balance fee if you set up direct deposit, link a checking account, or maintain balances elsewhere with them.
- Online banks and credit unions often have lower or no minimum balance requirements than traditional brick-and-mortar banks.
- A $10 monthly fee on a $500 balance costs you 24% per year in fees alone, making it worth shopping for a bank with no minimum or a lower one.
How banks determine which accounts have minimums
The minimum balance requirement depends on the account type and the bank's business model. A basic savings account at a large national bank might require $300 to $500. A premium or high-yield savings account might require $10,000 or more because the bank expects to pay you higher interest and wants larger deposits to offset that cost. A money market account often has a higher minimum — sometimes $2,500 — because it offers check-writing or debit card access.
Online banks and credit unions tend to have lower or zero minimums because they have fewer physical branches and lower overhead costs. If you bank with a credit union, ask whether you need to maintain a minimum share (deposit) in a savings account to keep your membership active — this is separate from a balance requirement but works similarly.
Some banks tier their requirements: you might need $500 to open the account, but only $100 to avoid the monthly fee once it is open. Others waive the minimum entirely if you meet one alternative condition, such as receiving a paycheck via direct deposit each month.
When the bank checks your balance and how it affects you
The timing of the balance check matters more than you might think. If your bank checks your balance daily, a single day below the minimum — even if you deposit money the next day — can trigger the fee. If it checks only on the last day of the month, you have more flexibility to dip below temporarily during the month.
Some banks use an average daily balance method: they add up your balance for each day of the month and divide by the number of days. This protects you if you dip below the minimum for a few days but recover. Others use the lowest balance method: if your balance ever falls below the minimum on any single day, you owe the fee, regardless of what happens later.
Your account agreement or the bank's website should state the exact rule. If it does not, call the bank and ask: "On which day or days do you check whether my balance meets the minimum?" and "If I dip below for one day, do I pay the fee?" Write down the answer and keep it.
Alternatives to meeting the minimum balance
Many banks offer ways to waive the minimum balance fee without keeping a large balance. The most common are:
- Direct deposit. Set up payroll or benefit deposits to hit your account automatically each month. Some banks waive the minimum if you receive at least one direct deposit per month; others require a minimum deposit amount, such as $500.
- Linked checking account. Open a checking account at the same bank and maintain the minimum there instead. Some banks combine the balances across both accounts.
- Other account balances. A few banks let you count money in a money market account, CD, or investment account toward the minimum for your savings account.
- Monthly transfers. Some banks waive the fee if you transfer a set amount into the account each month, such as $25.
- Age or student status. Banks often waive minimums for accounts held by minors or full-time students.
If you do not meet any of these conditions, the fee is unavoidable unless you maintain the balance or switch banks.
The real cost of minimum balance fees
A $10 monthly fee on a $500 balance costs you $120 per year. That is 24% of your balance in fees alone — far more than any interest the bank will pay you. On a $1,000 balance with a $15 monthly fee, you lose $180 per year, or 18% of your money.
This is why minimum balance requirements matter most to people with small savings. If you have $5,000 or more, a $10 fee is 2.4% per year, which is painful but survivable. If you have $300, that same fee is 40% per year, and it makes no sense to keep money there.
If you cannot meet the minimum without hardship, move your account. Online banks such as Marcus, Ally, and Discover have no minimum balance requirements and often pay higher interest rates than traditional banks. Credit unions typically have lower minimums and may waive them for members who use direct deposit.
How to find your bank's minimum balance rule
Your account agreement — the document you signed or agreed to online when you opened the account — contains the minimum balance requirement and the fee amount. You can usually find it on your bank's website under "Account Terms" or "Disclosures." If you cannot locate it, log into your online banking portal; many banks display the minimum and current fee in the account details section.
If you still cannot find it, call your bank's customer service line and ask for the specific minimum balance requirement for your account type and the exact day or method the bank uses to check it. Ask also whether any waivers apply to you — direct deposit, linked accounts, or other conditions.
Write down the answer and the date you called. If the bank charges you a fee later and you believe you met the requirement, you will have proof of what you were told.

Frequently Asked Questions
What happens if my balance drops below the minimum for one day?
It depends on your bank's checking method. If they check daily, you pay the fee. If they check only on the last day of the month or use an average balance method, one day below the minimum may not trigger a fee. Call your bank and ask which method they use, or check your account agreement.
Can I negotiate a lower minimum balance with my bank?
Rarely. Large banks have set policies and do not negotiate individual accounts. Credit unions and smaller regional banks are sometimes more flexible, especially if you have multiple accounts or a long history with them. It is worth asking, but switching to a bank with no minimum is usually faster than negotiating.
Do I have to pay the fee if I did not know about the minimum?
Yes. The minimum balance requirement is disclosed in your account agreement, which you agreed to when you opened the account. Lack of knowledge does not waive the fee. However, if the bank made an error or if you can show you were not properly informed, you can ask for a one-time courtesy reversal of the fee.
Is the minimum balance the same as the opening balance?
No. The opening balance is what you deposit to create the account — often $25 to $100. The minimum balance is what you must keep in the account to avoid a monthly fee, which is usually higher. You can withdraw money after opening, but if your balance falls below the minimum, you pay the fee.
Do online banks really have no minimum balance requirements?
Most do not, which is one reason they can offer higher interest rates. They have lower overhead and do not need to charge fees to offset the cost of maintaining small accounts. However, always check the specific bank's terms before opening an account, as requirements can change.
