The minimum balance depends on your bank, not on you

There is no universal rule for how much you must keep in a savings account. Your bank sets the minimum, and it varies widely—some banks require nothing, others require $25, $100, $500, or more. The amount your bank demands has nothing to do with your personal finances or how much you should save; it is purely a threshold the institution uses to decide whether to charge you a monthly fee or close your account.

The minimum balance requirement appears in your account agreement, usually under a section called "Minimum Balance" or "Account Requirements." If you do not meet it, the bank typically charges a monthly maintenance fee—often $5 to $15—or closes the account after a set period of inactivity. Some banks waive the minimum if you set up direct deposit, maintain a linked checking account, or keep a certain amount in other products with them.

Your decision about how much to actually keep is separate from what the bank requires. That is a personal choice based on your emergency fund, your spending patterns, and your goals.

Key Takeaways

  • Your bank's minimum balance requirement is a fee threshold, not a savings target—check your account agreement to find your specific bank's number.
  • If you fall below the minimum, your bank will charge a monthly fee or eventually close the account, so verify the requirement before opening.
  • Many banks waive minimums for accounts with direct deposit, linked checking accounts, or other products held at the same institution.
  • How much you should actually save is separate from the minimum—that depends on your emergency fund goal, monthly expenses, and financial situation.
  • High-yield savings accounts often have lower or no minimums but may require higher balances to earn the advertised interest rate.

What happens when you fall below the minimum

If your balance drops below your bank's stated minimum, one of two things occurs: the bank charges you a monthly fee, or it closes the account. The fee is usually $5 to $15 per month and appears on your statement as "maintenance fee," "low balance fee," or "minimum balance fee." This fee is charged whether you use the account or not—it is purely a penalty for not meeting the threshold.

Some banks will close an account if the balance stays below the minimum for 30, 60, or 90 days. When they close it, they send you a check for whatever balance remains and report the closure to ChexSystems, a banking history database. A closure on your record can make it harder to open accounts at other banks for up to five years, though the impact varies by institution.

The fee compounds the problem: if you have $50 in the account and the minimum is $100, a $10 monthly fee means your balance drops to $40 the next month, triggering another fee. This is why checking your bank's minimum before opening is important—a low-minimum or no-minimum account prevents this trap entirely.

How to find your bank's specific requirement

Your bank's minimum balance requirement is in your account agreement, which you received when you opened the account. If you have it, search for "minimum balance" or "account requirements." If you do not have the document, log into your online banking portal and look for "account details," "account terms," or "disclosures"—most banks post this information there.

You can also call your bank's customer service line or visit a branch and ask directly. When you call, have your account number ready and ask: "What is the minimum balance requirement for my savings account, and what happens if I fall below it?" Also ask whether the minimum can be waived—many banks waive it for direct deposit or if you maintain a linked checking account.

If you are considering opening a new account, compare minimums across banks before you sign up. Online banks and credit unions often have lower or no minimums than traditional brick-and-mortar banks. A bank with no minimum saves you from fees entirely, even if you are going through a tight month.

The difference between minimum balance and interest-earning thresholds

Some banks have two separate numbers: a minimum balance requirement (the amount you must keep to avoid fees) and an interest-earning threshold (the amount you must keep to earn the advertised interest rate). These are not the same thing.

For example, a bank might have a $0 minimum balance requirement but require $10,000 to earn the advertised 4.5% annual percentage yield (APY). If you keep $5,000, you avoid fees, but your interest rate might drop to 0.01% or lower. This is common with high-yield savings accounts, which advertise attractive rates but only pay them on larger balances.

Read the fine print in your account agreement under "Interest Rate" or "APY Schedule." It will show the balance tiers and the rate you earn at each level. If you plan to keep a small balance, confirm what rate you will actually receive, not just the advertised rate.

How much you should actually save, separate from the minimum

The amount you should keep in a savings account depends on your situation, not on your bank's requirement. Financial advisors often suggest keeping three to six months of living expenses in an accessible savings account as an emergency fund. To calculate this for yourself, add up your monthly expenses—rent or mortgage, utilities, groceries, insurance, transportation—and multiply by three or six.

If your monthly expenses are $3,000, three months of expenses is $9,000 and six months is $18,000. This is a target to work toward, not something you need when ready. Many people build their emergency fund gradually, adding $50 or $100 per paycheck until they reach their goal.

Beyond an emergency fund, you might keep additional money in savings for a specific goal—a down payment on a house, a car repair, a vacation. The amount is entirely up to you. The key is separating this personal savings goal from your bank's minimum balance requirement, which is just a fee threshold.

Banks and credit unions with low or no minimums

If you want to avoid minimum balance fees entirely, several types of institutions offer accounts with no minimum or very low minimums. Online banks like Ally, Marcus, and Discover typically have $0 minimums because they have lower overhead costs than physical branches. Credit unions often have $25 or $50 minimums, sometimes waived if you maintain a linked checking account.

Some traditional banks also offer no-minimum savings accounts, though they may pay lower interest rates than high-yield alternatives. Before opening any account, confirm three things: the minimum balance requirement, what happens if you fall below it, and what interest rate you will earn on your actual balance.

If you already have an account with a high minimum and you are struggling to meet it, contact your bank and ask about switching to a different savings product with a lower threshold. Many banks will move your money to a different account type without closing your original account, which avoids the ChexSystems closure record.

Frequently Asked Questions

What happens if my balance goes below the minimum for just one day?

Most banks calculate the minimum balance requirement on a daily basis or monthly average basis—check your account agreement to see which applies to you. If it is daily, dipping below for one day can trigger a fee. If it is monthly average, one low day may not matter if your average for the month stays above the minimum. Call your bank to confirm how they measure it.

Can a bank close my account without warning?

Banks can close accounts, but they must give you notice—usually 30 to 60 days. They will send a letter explaining the closure and why. If your account is closed due to low balance, the bank sends you a check for your remaining balance. The closure appears on your ChexSystems record, which can affect future account openings.

Do savings accounts at credit unions have different minimums than banks?

Credit unions often have lower minimums than traditional banks—sometimes $25 or $50 instead of $100 or $500. Some credit unions waive the minimum entirely if you maintain a linked checking account or set up direct deposit. Minimums vary by credit union, so ask before you join.

If I have multiple savings accounts at the same bank, do they count toward the minimum separately?

Each account is usually treated separately—your bank calculates the minimum balance requirement for each account independently. If you have two savings accounts and one falls below the minimum, only that account is charged a fee. Some banks allow you to link accounts to meet the minimum combined, but this is not standard; ask your bank directly.

Does the minimum balance requirement affect my credit score?

No. A low balance or a closed savings account does not appear on your credit report and does not affect your credit score. However, a closed account does appear on ChexSystems, which banks use to decide whether to open accounts with you. This is a separate system from credit reporting.
