Minimum balance requirements vary by bank and account type, not by law

There is no federal rule that forces you to keep a certain amount in savings. The minimum balance requirement is set by each individual bank, and many banks have none at all. Some accounts require you to hold $25; others require $10,000 or more. Some require nothing. The amount depends on the account tier you choose and the bank's own policies.

What matters is understanding your specific bank's rule before you open an account or after you already have one. If you fall below the minimum, the bank typically charges a monthly fee—usually $5 to $15—until you bring the balance back up. Some banks will close the account if you stay below the minimum for too long.

Key Takeaways

  • Minimum balance requirements are set by individual banks, not by government, and range from zero to several thousand dollars depending on the account type.
  • If you drop below the minimum, your bank will charge a monthly maintenance fee, usually between $5 and $15, until you restore the balance.
  • You can find your account's minimum balance requirement in your account agreement, on your bank's website, or by calling customer service.
  • Many banks offer no-minimum savings accounts, often called basic or starter accounts, though they may pay lower interest rates.
  • The minimum balance rule applies to the account itself, not to your total money across all accounts—falling short in one account does not affect another.

Where to find your bank's minimum balance rule

Your account agreement is the official source. This document came with your account when you opened it, or you can request it from your bank. Look for sections titled "Account Requirements," "Fees," or "Minimum Balance." If you opened the account online, log into your bank's website and search for your account terms—most banks have a downloadable PDF.

If you cannot locate the agreement, call your bank's customer service line. They can tell you the minimum balance for your specific account in under five minutes. Write down the exact amount and ask whether the bank counts the balance on a specific day each month (some banks check on the last day; others check daily and require you never to dip below).

What happens when you fall below the minimum

The first consequence is a monthly fee. If your minimum is $500 and your balance drops to $450, the bank charges you a maintenance fee—typically $5 to $15—at the end of the month or on a set date. That fee comes out of your account, lowering your balance further. If you stay below the minimum for several months, the fees compound.

Some banks will close your account if you remain below the minimum for 60 to 90 days without bringing it back up. When an account closes, any remaining balance is mailed to you as a check, and the account appears on your banking history. This can affect your ability to open accounts at other banks, because banks use ChexSystems (a banking history database) to screen new customers.

Accounts with no minimum balance requirement

Many banks now offer savings accounts with zero minimum balance. These are often called basic savings accounts, starter savings accounts, or no-frills accounts. They typically pay a lower interest rate than premium accounts, but they carry no monthly fee and no balance requirement. If you have very little money to save or irregular income, this type of account may be the better fit.

Online banks are more likely to offer no-minimum accounts than traditional brick-and-mortar banks. Credit unions also frequently have no-minimum savings options. If your current bank charges a fee for falling below the minimum, switching to a no-minimum account at the same bank (if available) or moving to a different bank may save you money over time.

How banks calculate your balance against the minimum

Banks use one of two methods: daily balance or statement balance. With daily balance, the bank checks your account every single day, and you must never drop below the minimum—even for one day. With statement balance, the bank checks your balance on a specific date each month, usually the last day of the statement cycle. If you dip below on day 15 but recover by day 30, you are safe.

Your account agreement will state which method your bank uses. If it is not clear, ask customer service. Daily balance requirements are stricter and more common at larger banks. Smaller banks and credit unions are more likely to use statement balance, which gives you more flexibility.

Minimum balance versus overdraft protection

A minimum balance requirement is different from overdraft protection. The minimum is the amount you are expected to keep in the account to avoid fees. Overdraft protection is a separate service that covers you if you spend more than you have—the bank lends you the difference and charges a fee. You can have a minimum balance requirement without overdraft protection, or overdraft protection without a minimum balance requirement.

If your bank offers overdraft protection, read the terms carefully. Overdraft fees are often $25 to $35 per transaction, and they can add up quickly if you overdraw multiple times in one month. Some people turn off overdraft protection to avoid these fees, which means transactions will be declined instead of covered.

Moving money to meet the minimum without losing access

If you have the money but it is in a different account, you can transfer it to meet the minimum. The transfer takes one to three business days if you are moving money between banks, or it can be when ready if both accounts are at the same bank. Once the money arrives and your balance is above the minimum, the fee will not be charged for that month.

Some people keep a small amount in a high-minimum account just to avoid fees, even if they do not use it regularly. This works only if the interest the account earns is higher than the fee you would pay for falling below the minimum. Do the math: if the minimum is $1,000, the fee is $10 per month, and the account pays 0.01% annual interest, you earn about $1 per year but pay $120 in fees—a net loss of $119. In this case, switching to a no-minimum account makes more sense.

Frequently Asked Questions

Can a bank change its minimum balance requirement without telling me?

Banks must notify you of changes to account terms, usually by mail or email, and they must give you time to close the account without penalty if you disagree. Check your mail and email for notices from your bank. If you see a new fee on your statement, contact the bank to confirm whether a policy change occurred.

Does the minimum balance count money in linked accounts?

No. The minimum applies only to the specific account. If you have a checking account and a savings account at the same bank, the minimum for the savings account is based only on what is in savings. Money in checking does not count toward the savings minimum, and vice versa.

What if I am below the minimum because of a bank error?

Contact your bank when ready and explain the error. If the bank confirms it made a mistake, they will usually reverse the fee and restore your balance. Keep records of all communications. If the bank disputes your claim, you can file a complaint with the Consumer Financial Protection Bureau (CFPB).

Do savings accounts at credit unions have minimum balance requirements?

Some do and some do not. Credit unions set their own minimums just like banks do. Call your credit union or check your account agreement to find out. Many credit unions advertise no-minimum savings accounts as a member benefit, but it varies by institution.

If I close my account while below the minimum, do I owe the bank?

No. When you close an account, the bank sends you any remaining balance as a check, even if it is below the minimum. You do not owe money. However, the closure will appear on your banking history, which may affect your ability to open accounts elsewhere.
