The short answer: it depends on your bank and your habits
There is no single amount you must keep in a checking account. Some banks require a minimum balance — a floor below which your account gets charged a fee or closed. Others have no minimum at all. The amount varies from zero dollars to several thousand, depending on which bank you choose and what type of account you open.
What matters more than the minimum is keeping enough to cover the checks and transfers you make without overdrawing — spending money you do not have. That number is different for everyone and depends on how often you get paid, how many bills you pay, and how much cushion you want between your balance and zero.
Key Takeaways
- Minimum balance requirements range from zero to several thousand dollars and vary by bank and account type; check your bank's specific rules before opening an account.
- You should keep enough in your account to cover your regular bills and expenses between paychecks, plus a buffer to avoid overdraft fees.
- Overdraft fees typically cost $25 to $35 per transaction and can add up quickly if you spend more than your balance.
- If you cannot meet a minimum balance requirement, you can switch to a bank with no minimum or a lower one at no penalty.
What minimum balance requirements actually are
A minimum balance requirement is the lowest amount a bank says you must keep in your account at all times. If your balance drops below that number, the bank charges you a monthly fee — usually $10 to $15 — or closes your account.
Not all banks have minimums. Many online banks and credit unions have zero-dollar minimums, meaning you can open an account with $1 and never face a fee for a low balance. Traditional banks often have minimums ranging from $100 to $500 for basic checking, and higher minimums ($1,000 to $2,500 or more) for premium accounts that come with extra features like higher interest rates or waived fees.
The requirement is usually based on your daily balance — what you have in the account on any given day — not your average balance over a month. This means if you dip below the minimum even once, you may be charged, even if you bring the balance back up the next day.
How much you need to avoid overdraft fees
Overdraft fees are separate from minimum balance fees. An overdraft happens when you spend more money than you have in your account. When this occurs, your bank either declines the transaction (costing you nothing but embarrassment at the register) or covers it and charges you a fee — typically $25 to $35 per overdraft.
To avoid this, you need a balance that covers all the money leaving your account between now and your next deposit. If you get paid every two weeks and spend roughly $800 in that time, you should aim to keep at least $800 in your account at all times, plus a cushion. A common target is one month of expenses, though even $200 to $500 can prevent most overdrafts if you check your balance regularly.
Some banks offer overdraft protection, which links your checking account to a savings account or credit line. If you overdraw, the bank automatically transfers money from the linked account instead of charging a fee. This costs nothing if you use it, but you still need money in the linked account to transfer.
The difference between what you need and what you should keep
The minimum balance your bank requires is not the same as the amount you should actually keep. A bank might require $100, but that does not mean $100 is enough to live on safely.
Think of it this way: the minimum is what the bank demands to avoid penalties. The amount you should keep is what you need to avoid financial stress. If you keep exactly the minimum and then face an unexpected expense — a car repair, a medical bill, a late paycheck — you will overdraw when ready.
Financial advisors often suggest keeping one to three months of expenses in checking, though that is a goal many people work toward over time, not a starting point. For someone just opening their first account, keeping enough to cover two weeks of expenses is a realistic and protective target.
How to choose a bank based on minimum balance requirements
If you cannot meet a bank's minimum balance requirement, you have options. You do not have to stay with a bank that charges you for being poor.
Online banks like Ally, Charles Schwab, and Discover typically have zero-dollar minimums and no monthly fees. Credit unions often have low or no minimums as well. If you prefer a physical branch, many regional and community banks have checking accounts with no minimum or minimums under $100.
When comparing banks, look at the full picture: the minimum balance, the monthly fee if you fall below it, overdraft fees, and whether the bank offers overdraft protection. A bank with a $500 minimum but no overdraft fees might cost you less over time than a bank with no minimum but $35 overdraft fees.
What happens if you cannot maintain the minimum
If you open an account and later find you cannot keep the minimum balance, you can close it and move to another bank. There is no penalty for closing a checking account, and you can do it anytime.
Before you close, make sure all automatic payments and direct deposits are switched to your new account. This usually takes a few days to set up. Some banks will waive the minimum balance requirement temporarily if you contact them and explain your situation, though this is not may provide.
If your account is closed due to a low balance, the bank will send you any remaining money and may report the closure to ChexSystems, a banking history database. This can make it harder to open a new account at other banks for a period of time. To avoid this, close the account yourself before the bank does.
Building a checking account balance over time
You do not need to start with a large balance. Most people open a checking account with whatever they have on hand — $50, $100, or a few hundred dollars — and build from there as they receive paychecks.
A practical approach is to deposit your paycheck, pay your bills and regular expenses, and leave the remainder in the account. Over a few months, this remainder grows into a cushion. Once you have enough to cover two weeks of expenses, you have reduced your overdraft risk significantly. Once you have a month's worth, you have real financial breathing room.
If you receive irregular income or have variable expenses, aim higher — three months of expenses if possible. If your income and expenses are predictable, two months is often enough.
Frequently Asked Questions
Can a bank close my account if I do not meet the minimum balance?
Yes. Banks can close accounts for low balances, usually after sending you a warning letter. The closure is not when ready — you typically have 30 days notice — so you have time to move your money to another bank. Close the account yourself before the bank does to avoid a negative mark on your banking history.
What is the difference between minimum balance and overdraft protection?
Minimum balance is a requirement the bank sets; if you fall below it, you pay a fee. Overdraft protection is a service that prevents overdrafts by automatically transferring money from another account. You can have both, neither, or one without the other, depending on your bank.
If I keep money in savings instead of checking, does it count toward my minimum?
No. Minimum balance requirements explore only to the checking account itself. Money in savings, money market accounts, or other accounts does not count. However, if you link a savings account for overdraft protection, the bank can pull from savings to cover overdrafts.
How often does the bank check if I meet the minimum balance?
Most banks check your balance daily. If you fall below the minimum on any single day, you may be charged a fee at the end of the month, even if you bring the balance back up the next day. Some banks check the average balance over the month instead, but this is less common.
Do I need to keep the minimum balance in cash, or can it be a debit card balance?
The minimum balance is the actual money in your account, whether you think of it as cash or not. A debit card is just a tool to access that money. The balance itself is what counts toward the minimum.
