The minimum balance depends on your bank, not on you

There is no universal rule for how much money must sit in a savings account. Your bank sets its own minimum, and it varies widely—some banks require nothing at all, while others want $500 or $2,500 or more before they will open an account for you. A few banks have no minimum balance requirement at any point. The amount your bank requires has nothing to do with how much money you personally need to save.

The minimum balance requirement is a threshold the bank uses to decide whether to open an account and whether to charge you a monthly fee. If your balance drops below that threshold, the bank may charge you a maintenance fee—typically $5 to $15 per month—or close the account. Some banks waive the fee if you set up direct deposit or maintain a linked checking account.

Before you open a savings account, check the bank's disclosure document or website for the exact minimum. It will be listed under "account requirements" or "minimum balance." If you cannot find it, call the bank and ask directly: "What is the minimum balance required to open this account, and what happens if my balance falls below it?"

Key Takeaways

  • Minimum balance requirements are set by each individual bank and range from zero to several thousand dollars.
  • If your balance falls below the minimum, your bank may charge a monthly fee or close the account entirely.
  • Some banks waive the minimum if you set up direct deposit or keep a linked checking account active.
  • The minimum balance requirement is separate from how much money you should personally save for emergencies or goals.
  • You can compare minimums across banks before opening an account by checking their websites or calling customer service.

What happens when your balance drops below the minimum

If your account balance falls below the bank's stated minimum, one of three things typically happens. The most common outcome is a monthly maintenance fee—usually $5 to $15—charged directly to your account. This fee reduces your balance further, which can trigger another fee the following month if you do not deposit money in the meantime.

Some banks will close your account if the balance stays below the minimum for a set period, often 30 to 90 days. When an account closes, any remaining balance is mailed to you as a check, and the account is reported to ChexSystems, a banking history database. This report can make it harder to open accounts at other banks for several years.

A smaller number of banks straightforward freeze the account—you cannot withdraw money or earn interest, but the account remains open and no fee is charged. This is rare, but it does happen. Your account agreement will specify which outcome applies to your account.

How minimum balance requirements differ across bank types

Traditional banks (Chase, Bank of America, Wells Fargo) typically require $300 to $2,500 to open a savings account, depending on the specific product. Some of their basic savings accounts have no minimum, but those accounts also pay very little interest. Their premium savings products—marketed as "high-yield" or "money market" accounts—often have higher minimums, sometimes $10,000 or more.

Online banks (Ally, Marcus, Discover) almost always have zero minimum balance requirements. Because they have no physical branches, their operating costs are lower, and they can afford to waive the minimum. These banks also tend to pay higher interest rates on savings, which makes them worth considering even if you have a small balance.

Credit unions vary widely. Some require you to buy a share (usually $25 to $100) to become a member, and then have no minimum balance on the savings account itself. Others have no membership fee but require a minimum balance of $500 or more. Call your local credit union to ask.

Savings banks and smaller regional banks fall somewhere in the middle—typically $100 to $1,000 minimum. These banks often offer slightly higher interest rates than the largest national banks but lower rates than online banks.

Minimum balance versus how much you should actually save

The bank's minimum balance requirement is not the same as a personal savings goal. Your bank might require $500 to keep the account open without fees, but financial advisors generally recommend keeping three to six months of living expenses in a savings account for emergencies. That number depends entirely on your situation: your monthly expenses, your job stability, whether you have dependents, and your debt level.

If your monthly expenses are $3,000, three months of emergency savings would be $9,000. If your monthly expenses are $1,500, three months would be $4,500. Neither of these amounts has anything to do with what your bank requires. You should save what you need for your own security, separate from what the bank requires to keep the account open.

Some people open a savings account with the bank's minimum just to have the account, then save additional money in a separate account at a different bank that pays higher interest. This is a valid strategy if you want to keep your emergency fund somewhere accessible but separate from your everyday checking account.

How to find a bank with no minimum balance requirement

If you want to open a savings account but do not have much money to start with, online banks are your fastest option. Ally Bank, Marcus by Goldman Sachs, Discover Bank, and American Express Personal Savings all have zero minimum balance requirements and no monthly maintenance fees. You can open an account online in about 10 minutes with just an email address, Social Security number, and a valid ID.

Many online banks also pay higher interest rates than traditional banks—currently in the range of 4% to 5% annually, though this changes with Federal Reserve decisions. Because they have lower overhead, they can afford to pay you more for keeping money with them.

If you prefer to bank in person, call local credit unions or smaller regional banks in your area and ask about their minimum balance requirements. Some will have none, or will waive the minimum if you set up direct deposit from your employer. A few traditional banks also offer basic savings accounts with no minimum, though you may have to ask specifically—these products are not always advertised prominently.

When banks waive the minimum balance requirement

Even if a bank has a stated minimum balance requirement, it often waives the fee if you meet certain conditions. The most common waiver is direct deposit—if your paycheck or government benefits are deposited directly into the account, the bank will not charge a maintenance fee even if your balance falls below the minimum. This is because direct deposit brings the bank steady transaction volume and customer stability.

Some banks waive the minimum if you maintain a linked checking account with them, or if you have a certain total balance across all your accounts combined. A few banks waive it if you set up automatic transfers from a checking account to savings, even if the transfer is just $25 per month. Read your account agreement or ask your bank what waivers are available.

These waivers are worth investigating before you open an account. If you receive direct deposit, you may be able to open an account at a bank with a higher minimum without ever paying a fee. If you do not receive direct deposit, an online bank with no minimum at all is usually the better choice.

Frequently Asked Questions

Can I open a savings account with $50?

Yes, if you choose an online bank or a bank with no minimum balance requirement. Many online banks have zero minimum to open an account. Some traditional banks and credit unions also have no minimum, but you will need to call and ask. If you open an account at a bank with a minimum requirement and your balance is below it, you may be charged a monthly fee.

What happens if I never deposit money after opening the account?

If your account balance stays at zero or below the minimum for 30 to 90 days, the bank will likely close it. When an account closes, any remaining balance is mailed to you, and the closure is reported to ChexSystems. This can make it harder to open accounts elsewhere. Some banks will charge a monthly fee instead of closing the account, which would result in a negative balance.

Do I need to keep a certain amount in savings for taxes or legal reasons?

No. There is no legal requirement to keep any specific amount in a savings account. The only requirement is what your bank sets. How much you save is a personal financial decision based on your expenses and goals, not a legal obligation.

If I have $10,000 in savings, should I split it between multiple banks?

That depends on your goals. If you want to earn the highest interest rate, compare rates across banks and put your money where the rate is best. If you are concerned about account security, the FDIC insures up to $250,000 per account at each bank, so $10,000 at one bank is fully protected. Splitting money between banks makes sense only if different banks offer significantly different interest rates or features you want.

Can a bank change its minimum balance requirement after I open an account?

Yes, banks can change their requirements, but they must notify you in advance—usually 30 days. If your bank raises the minimum and your balance falls below it, you will start being charged a fee unless you deposit more money or the bank waives the fee for you. Check your bank statements and emails for notices about account changes.
