The answer depends on your bank, your account type, and what you're trying to avoid
There is no single number that works for everyone. Banks set their own rules about how much you must keep in a savings account, and those rules vary widely. Some accounts have no minimum at all. Others require $25, $500, or even $25,000. The amount also depends on whether you're opening a regular savings account, a money market account, or a high-yield savings account—each type has different requirements.
What matters most is understanding what happens if you fall below the minimum your specific bank requires. Some banks charge a monthly fee. Others close the account. A few will convert you to a different account type automatically. Before you open any savings account, you need to know three things: the opening deposit required, the minimum balance required to keep the account open, and what the bank does if you drop below it.
Key Takeaways
- Most banks require either no minimum balance or a minimum between $25 and $500 to keep a savings account open, though some require much more.
- The opening deposit (what you need to start the account) is often different from the minimum balance (what you need to keep it open), so ask about both.
- If you fall below the minimum, your bank will either charge a monthly fee, close the account, or move you to a different account type—read the disclosure document to know which.
- Online banks and credit unions often have lower or no minimums than traditional brick-and-mortar banks.
- Your employer's direct deposit or automatic transfers can sometimes waive the minimum balance requirement entirely.
What banks actually require as a minimum
Traditional banks (the kind with physical branches) typically require between $100 and $500 to open a savings account and keep it open. Some require more if you want to earn a higher interest rate. Online banks usually have lower minimums—many have none at all, or require only $1 to $25. Credit unions often fall somewhere in the middle, though some have no minimum.
The opening deposit is what you put in on day one. The minimum balance is what you must maintain afterward. These are not always the same. You might need $500 to open an account but only $100 to keep it open. Or you might need $1,000 to open it but zero to keep it open. The bank's disclosure document (sometimes called a "Truth in Savings" form or account agreement) will spell out both numbers. If you cannot find it on the bank's website, call and ask directly.
Some banks waive the minimum balance requirement if you set up direct deposit from your paycheck, or if you maintain a certain balance in a linked checking account. Others waive it if you sign up for paperless statements or online banking. These waivers are real and can save you money, but you have to ask about them—banks do not always advertise them prominently.
What happens if you drop below the minimum
If your balance falls below the bank's minimum, one of three things will happen. The most common is a monthly maintenance fee—usually $5 to $15—charged until you bring the balance back up. Some banks charge this fee only once, others charge it every month you stay below the minimum. A few banks will close the account after a set period of time (often 30 to 90 days) if the balance does not recover. A third option, less common now, is that the bank converts you to a different account type automatically, usually one with no minimum but also no interest.
The fee itself might seem small, but it compounds. A $10 monthly fee on a $50 balance is 120 percent annual interest—you are losing money just to keep the account open. If you know you cannot maintain the minimum, it is better to choose an account with no minimum from the start, or to move your money to a bank that does not charge.
Read the account agreement before you open the account. Look specifically for the section on fees or "what happens if your balance falls below the minimum." If you cannot find it, ask the bank representative to show you in writing. Do not rely on what someone told you over the phone—the written agreement is what the bank will enforce.
How much you should actually keep in savings
The bank's minimum and the amount you should personally keep are two different questions. Your bank might require $100, but financial advisors often suggest keeping three to six months of living expenses in an easily accessible savings account. That number depends entirely on your situation: your income stability, your monthly expenses, whether you have dependents, and whether you have other money set aside.
If you are paid regularly and have stable expenses, three months might be enough. If your income is unpredictable (you are self-employed or work on commission), six months is more realistic. If you have dependents or high monthly costs, you might need more. The point is that this number is about your financial security, not about what your bank requires. You should aim to keep whatever amount lets you sleep at night if an emergency happens—job loss, medical bill, car repair.
Start by calculating your monthly expenses: rent or mortgage, utilities, food, insurance, transportation, and anything else you pay for regularly. Multiply that by three or six. That is a reasonable target. Your bank's minimum is a separate floor—you must stay above it to avoid fees, but your personal goal should be higher.
Opening deposit versus ongoing minimum: what you need to know
Banks often advertise a low opening deposit to get you in the door, then hit you with a higher ongoing minimum. For example, a bank might say "open with just $25" but require you to maintain a $500 balance to avoid fees. This is legal and common, but it catches people off guard.
Before you open an account, write down two numbers from the bank's disclosure document: the opening deposit and the minimum balance. If they are different, ask what happens if you fall below the ongoing minimum. Some banks will let you go below it temporarily (say, for one billing cycle) before charging a fee. Others charge when ready. Some give you a grace period of 30 days to bring it back up. These details matter if you are living paycheck to paycheck.
If the ongoing minimum is higher than you can realistically maintain, do not open that account. Choose one with a lower minimum or none at all. Online banks and credit unions are often better options if you have limited funds to keep on hand.
Minimums at different types of banks
| Bank Type | Typical Opening Deposit | Typical Ongoing Minimum | What Happens If You Drop Below |
|---|---|---|---|
| Traditional bank (large) | $100–$500 | $100–$500 | Monthly fee ($5–$15) or account closure |
| Online bank | $0–$25 | $0–$25 | Usually nothing; no fees |
| Credit union | $25–$100 | $25–$100 | Monthly fee or account closure (varies by credit union) |
| High-yield savings account | $0–$1,000 | $0–$1,000 | Usually nothing; no fees |
How to find an account that fits your situation
If you have limited funds, start by looking at online banks and credit unions. Online banks almost never charge monthly maintenance fees and often have no minimum balance requirement. Credit unions are member-owned and sometimes more flexible with minimums, especially if you have a steady paycheck or direct deposit set up.
When you are comparing accounts, do not just look at the interest rate. Look at the minimum balance, the opening deposit, and the fee structure. A high interest rate is worthless if you are paying $10 a month in fees because you cannot maintain the minimum. A low-fee account with no minimum and a modest interest rate is usually the better choice if you are starting out.
Call or visit the bank's website and ask these specific questions: What is the opening deposit? What is the minimum balance to keep the account open? What happens if I fall below it? Are there any ways to waive the minimum (direct deposit, linked checking account, paperless statements)? Write down the answers and compare them across at least three banks before you decide.
Frequently Asked Questions
Can I open a savings account with no money and add funds later?
Some online banks allow you to open an account with $0 and deposit money whenever you want. Traditional banks almost always require at least a small opening deposit—usually $25 to $100—before the account is active. Check the bank's website or call to confirm whether they will let you open with zero dollars.
What if I cannot maintain the minimum balance right now?
Choose an account with no minimum or a very low minimum ($1 to $25). Online banks and some credit unions offer these. Once your financial situation improves, you can move to a different account type if you want a higher interest rate. There is no penalty for switching banks.
Does the minimum balance include money I am saving for a specific goal?
Yes. The bank counts all money in the account toward the minimum, regardless of why you are saving it. If you need to keep $500 in the account to avoid fees, that $500 counts whether it is emergency money, vacation money, or anything else. Some people open multiple accounts—one for the required minimum and one for actual savings—to work around this.
Will the bank charge me a fee if I go below the minimum for just one day?
It depends on the bank. Some charge a fee if your balance drops below the minimum at any point during the billing cycle. Others only charge if it stays below for a certain number of days. Read the fee schedule in your account agreement or call the bank to ask. This detail matters if you are living close to the edge.
Can I move money between accounts to avoid falling below the minimum?
Yes. If you have a linked checking account, you can transfer money from checking to savings to bring the balance back up. Some banks count linked accounts together for the purpose of the minimum balance requirement, so ask whether yours does. If it does, you can use your checking account as a buffer.
