Most banks require a minimum balance, but the amount and what happens if you fall short varies widely
Whether you need to keep a minimum balance in a savings account depends entirely on the bank and the specific account type. Some banks have no minimum at all. Others require anywhere from $25 to $25,000 or more, depending on the account tier. The key is that the requirement is set by the bank, not by law — there is no federal rule that says all savings accounts must have a minimum balance.
What matters more than the minimum itself is what the bank does when you fall below it. Some banks charge a monthly fee (usually $5 to $15). Others close the account. A few will straightforward move you to a different account type with lower requirements. Understanding which scenario applies to your account is what actually affects your wallet.
Key Takeaways
- Minimum balance requirements are set by individual banks and vary from zero to thousands of dollars depending on the account type.
- The consequence of falling below the minimum is usually a monthly fee, but some banks close accounts or convert them to a different product instead.
- Banks often waive minimum balance requirements if you set up direct deposit, maintain a linked checking account, or meet other conditions.
- Online banks and credit unions typically have lower or no minimum balance requirements compared to large national banks.
- Your account documents or the bank's website will state the exact minimum and the exact penalty for not meeting it.
How banks set and enforce minimum balances
A bank decides its minimum balance policy based on the account product itself. A basic savings account at a large national bank might have a $300 minimum. A high-yield savings account at the same bank might have no minimum. A premium savings account might require $50,000. These are not negotiable — they are part of the account's terms.
The bank monitors your balance daily or at the end of each statement cycle. If your balance drops below the minimum on even one day, many banks will charge the fee. Some banks look only at the ending balance on the last day of the month. Read your account agreement to know which method your bank uses, because the difference can mean the fee applies or does not.
When you fall below the minimum, the bank does not automatically close the account. Instead, it charges a fee — typically $5 to $15 per month — and the account stays open. However, if you stay below the minimum for an extended period (usually 90 days to a year, depending on the bank), the bank may close the account or convert it to a different account type with no minimum but also no interest.
When banks waive the minimum balance requirement
Most banks offer ways to avoid the minimum balance altogether, even if the account technically has one. The most common waiver is setting up direct deposit — if your paycheck or government benefits go directly into the account, the bank waives the minimum. Another common waiver is maintaining a linked checking account at the same bank; some banks waive the savings minimum if you keep your primary account open with them.
Other banks waive the minimum if you maintain a certain monthly deposit amount (not necessarily direct deposit), set up automatic transfers, or keep a combined balance across multiple accounts above a threshold. A few banks waive it straightforward for being under a certain age or over a certain age. Check your account agreement or call the bank directly to ask what waivers explore to your specific account.
These waivers are worth pursuing because they cost you nothing and eliminate the monthly fee risk. If you have direct deposit available, setting it up takes five minutes and removes the minimum balance concern entirely.
Minimum balances at different types of institutions
Large national banks (Chase, Bank of America, Wells Fargo, Citibank) typically require $300 to $500 for basic savings accounts, though they often waive it with direct deposit. Their premium or money market savings accounts may require $2,500 to $25,000.
Online banks (Ally, Marcus, Discover, American Express) almost never have minimum balance requirements, even for their highest-yield accounts. This is one of the main reasons people move to online banks — the fee structure is simpler and lower overall.
Credit unions vary widely, but many have no minimum balance requirement or require only $25 to $100. Credit unions are often more flexible about waiving minimums if you ask, since they are member-owned rather than shareholder-owned.
Savings accounts tied to investment or brokerage accounts sometimes have higher minimums ($10,000 or more) because they are part of a larger product suite.
The difference between minimum balance and average balance
Some banks use average daily balance instead of a single minimum. This means the bank adds up your balance for each day of the month and divides by the number of days. If the average comes out below the minimum, you pay the fee. This is actually harder to manage than a straightforward minimum because you cannot just deposit money on the last day and avoid the fee — you have to maintain the balance throughout the month.
Ask your bank explicitly whether it uses a minimum balance or an average daily balance requirement. The account agreement will state this, but it is worth confirming by phone because the difference affects your strategy for managing the account.
What to do if you cannot meet the minimum
If your account has a minimum balance you cannot consistently meet, you have three options: move to a bank with no minimum, ask your current bank to waive it, or accept the monthly fee as a cost of having the account.
Moving to an online bank is usually the simplest solution. You can open an account in minutes, and most online banks have no minimum balance and higher interest rates than traditional banks. The transfer takes a few days, but it is straightforward.
If you want to stay with your current bank, call and ask what waivers are available. Be specific: "I have direct deposit available — can I waive the minimum by setting that up?" or "I have a checking account with you — does that waive the savings minimum?" Banks often do not advertise all their waivers, so asking directly can reveal options you did not know existed.
If neither of those works and you decide to keep the account anyway, factor the monthly fee into your decision. A $10 monthly fee on a savings account earning 0.01% interest is a real cost, and you should know it upfront.
How minimum balance requirements affect your interest earnings
A minimum balance requirement does not directly reduce the interest you earn — interest is calculated on your actual balance, not on the minimum. However, the fee you pay for falling below the minimum can wipe out months of interest earnings.
For example, if you have $500 in a savings account earning 4.5% annual interest, you earn about $1.88 per month. A $10 monthly fee for falling below a $300 minimum costs more than five months of interest. Over a year, that fee costs you $120 while your interest earns you about $22.50. The fee is the real expense.
This is why minimum balance requirements matter most to people with smaller balances. If you have $50,000 in savings, a $300 minimum is irrelevant. If you have $500, it is a real consideration.
Frequently Asked Questions
Can a bank close my account if I go below the minimum balance?
A bank can close your account if you stay below the minimum for an extended period, usually 90 days to a year. However, most banks charge a monthly fee first and only close the account if you ignore repeated notices. If your balance drops below the minimum once, the bank will charge a fee but will not close the account when ready.
Does the minimum balance requirement explore to money I have in a linked checking account?
No. The minimum balance requirement applies only to the savings account itself. However, many banks waive the savings minimum if you maintain a linked checking account, so having both accounts at the same bank can eliminate the requirement entirely.
What happens to interest if I fall below the minimum balance?
Interest continues to accrue on whatever balance you have. Falling below the minimum triggers a fee, but it does not stop interest from being calculated. The fee is a separate charge from the interest you earn.
If I set up direct deposit, will the bank definitely waive my minimum balance?
Most banks waive the minimum with direct deposit, but not all. Check your account agreement or call your bank to confirm. Some banks require a minimum direct deposit amount (like $500 per month) rather than waiving it for any direct deposit.
Do savings accounts at online banks really have no minimum balance?
Most do, but check the specific account terms before opening. The vast majority of online banks advertise no minimum balance as a selling point, but a few specialty accounts may have requirements. The account details page will state the minimum clearly.
