Most savings accounts do have a minimum balance requirement, but it varies by bank and account type

Whether your savings account requires a minimum balance depends entirely on which bank you use and which specific account you open. Some banks require you to keep $0 in the account at all times. Others require $500, $1,000, or even $25,000. A few require nothing but charge a monthly fee unless you meet other conditions — like setting up direct deposit or maintaining a linked checking account.

The minimum balance is the lowest amount the bank says you must keep in the account. If your balance falls below that number, one of two things happens: the bank charges you a monthly fee (usually $5 to $15), or they close the account. Some banks do both. The requirement is set when you open the account, and it's written in the account agreement — the document you sign or click through but rarely read.

The practical effect is this: if you have $300 in a savings account with a $500 minimum, you're either paying a fee each month or you need to deposit $200 more. If you have $0 in an account with no minimum, you can leave it empty indefinitely without penalty.

Key Takeaways

  • Minimum balance requirements range from $0 to $25,000 depending on the bank and account type, and the requirement is stated in your account agreement.
  • If your balance drops below the minimum, the bank typically charges a monthly fee of $5 to $15, though some banks close the account instead.
  • Online banks and credit unions often have lower or no minimum balance requirements than traditional brick-and-mortar banks.
  • The minimum balance is calculated on a specific date each month — usually the last day of the month or the day your statement closes — so timing matters if you're close to the threshold.

How banks calculate whether you meet the minimum

The bank doesn't check your balance every single day. Instead, they measure it on a specific date — usually the last day of the month, or sometimes the day your statement closes. If your balance on that date is at or above the minimum, you're clear. If it's below, you owe the fee.

Some banks use an "average daily balance" method instead. They add up your balance for every day of the month and divide by the number of days. If that average is below the minimum, you pay the fee. This method is less common for savings accounts but more common for checking accounts, so check your agreement to know which one applies to you.

The timing matters. If you have $400 in an account with a $500 minimum, and you deposit $200 on the last day of the month, you meet the requirement. If you withdraw $200 on the last day of the month, you don't. Banks know this, which is why they're specific about the measurement date.

Which banks have no minimum balance requirement

Online banks — Ally, Marcus, Discover, Synchrony — typically have no minimum balance requirement for savings accounts. You can open an account with $1 and never deposit again without paying a fee. This is one reason online banks are popular for people who want to save small amounts or keep an emergency fund without worrying about a threshold.

Many credit unions also have no minimum or very low minimums ($25 to $100). The trade-off is that credit unions may require you to live or work in a specific area, or belong to a specific employer or organization, to join. Some credit unions have opened their membership to anyone, so it's worth checking if one near you has.

Traditional banks — Chase, Bank of America, Wells Fargo, Citibank — usually do require a minimum, often $500 or higher. However, they sometimes waive the requirement if you set up direct deposit, maintain a linked checking account, or keep a certain amount in other accounts at the same bank. The rules vary by branch and by region, so calling your bank directly is faster than guessing.

What happens if you fall below the minimum

The most common outcome is a monthly maintenance fee. The bank deducts it from your account on a set date each month — usually the same day they measure your balance. The fee is typically $5 to $15, though some banks charge more. Over a year, that's $60 to $180 in fees on an account that's supposed to help you save.

Some banks close the account if you stay below the minimum for several months in a row. They send you a notice (usually 30 days), then close it and send you a check for whatever balance remains. This is less common than a fee, but it happens, especially at larger banks.

A few banks do both: they charge a fee each month, and if you don't bring the balance up within a certain period, they close the account. Read your account agreement or call the bank to know which applies to you.

How to avoid minimum balance fees

The simplest route is to open an account with no minimum requirement. If you're already at a bank that requires one, you have three options: keep the balance above the minimum, switch to an account type that has no minimum, or switch banks.

If you want to stay at your current bank, ask whether they offer a savings account with no minimum. Many banks have multiple savings products — a basic one with a minimum and a higher-yield one with a higher minimum, or a basic one with no minimum but lower interest. The bank's website usually lists the requirements, but calling is faster if you're unsure.

If you're close to the minimum but not quite there, check whether your bank waives the fee for direct deposit or a linked checking account. Some do. It costs nothing to ask, and the bank's customer service line can tell you in one call whether you may have access to.

Minimum balance versus interest rate

A higher minimum balance doesn't mean a higher interest rate. Some banks require $500 and pay 0.01% annual percentage yield (APY). Others require $25,000 and pay 4.5% APY. The minimum and the rate are separate decisions the bank makes.

However, banks that require high minimums — $10,000 or more — often do pay higher rates. This is because they're targeting customers with more money to deposit. If you have that much to save, a high-minimum account might make sense. If you don't, a no-minimum account at an online bank will almost always pay more interest than a low-minimum account at a traditional bank.

Compare both the minimum and the rate before you open an account. A 4.5% APY with a $25,000 minimum is only useful if you have $25,000. A 4.0% APY with no minimum is better if you have $5,000.

Frequently Asked Questions

Can I have a savings account with $0 in it?

Yes, if the bank has no minimum balance requirement. Online banks like Ally and Marcus allow this. Traditional banks usually don't — they'll charge a monthly fee if your balance drops to $0, or close the account after a few months. Check your account agreement or call the bank to confirm.

What if I go below the minimum for just one day?

It depends on when the bank measures your balance. If they measure on the last day of the month and you dip below the minimum on the 15th but recover by the 30th, you won't be charged. If they measure on the day your statement closes, timing matters. Read your agreement or call to know the exact date.

Do I get charged a fee when ready if I fall below the minimum?

No. The bank measures your balance on a specific date, and if it's below the minimum on that date, they charge the fee a few days later — usually within a week. This gives you a short window to deposit money and avoid the fee, though you have to act quickly.

Can a bank change the minimum balance requirement?

Yes. Banks can change account terms, including the minimum balance requirement, but they must notify you in advance — usually 30 days. If they raise the minimum and you don't want to meet it, you can close the account and move your money elsewhere.

Is the minimum balance the same as the opening deposit?

No. The opening deposit is what you put in when you create the account — sometimes $0, sometimes $25. The minimum balance is what you must keep in the account going forward. Some banks require a $100 opening deposit but have no minimum balance after that.
