The minimum balance is the smallest amount of money a bank requires you to keep in your savings account at all times
Different banks set different minimums — some have none at all, some require $25, and others ask for $500 or more. If your balance drops below that number, even for a day, the bank charges you a fee. That fee is separate from any other charges and typically ranges from $5 to $15 per month, though it varies by bank.
The minimum exists because banks use customer deposits to make loans and investments. A higher minimum means the bank has more of your money to work with. In exchange, they offer you a place to store your money safely and sometimes pay you interest — a small amount of money the bank gives you just for keeping your account open.
Not every savings account has a minimum balance requirement. Many banks, especially online banks, have zero-minimum accounts. If you are starting out or have limited savings, a zero-minimum account avoids this fee entirely.
Key Takeaways
- The minimum balance is the lowest amount you must keep in the account; dropping below it triggers a monthly fee from your bank.
- Minimums vary widely — from zero dollars to several hundred dollars — depending on the bank and the type of savings account.
- Online banks and credit unions often have lower or no minimum balance requirements than traditional brick-and-mortar banks.
- If you cannot maintain the minimum, a zero-minimum account costs you nothing and works the same way as any other savings account.
How banks calculate whether you meet the minimum
Banks check your balance in different ways, and this matters. Some banks look at your balance on the last day of each month. Others check the average balance across the entire month — meaning if you dip below the minimum for even one day, you might still be charged. A few banks require you to never drop below the minimum, not even for an hour.
Ask your bank which method they use before you open the account. If you live paycheck to paycheck and your balance fluctuates, a bank that checks only the final day of the month is safer than one that checks the average. You have more control over where your money is on one specific date than across 30 days.
Some banks also let you meet the minimum across multiple accounts. If you have a checking account and a savings account at the same bank, they might count the combined balance. This is worth asking about if you keep money in both places.
Why the fee costs you more than it appears
A $10 monthly fee sounds small, but it adds up. If you pay that fee every month for a year, you have paid $120 just to keep your money in that account. Meanwhile, the bank might be paying you only $1 or $2 per year in interest — so the fee wipes out your earnings and then some.
The real cost is opportunity cost: that $10 could have stayed in your account and grown. Over time, small amounts compound. A $10 fee every month for five years is $600 that never had a chance to earn interest or help you reach a savings goal.
This is why choosing the right account matters. If you cannot comfortably keep $500 in savings, do not open an account that requires it. The fee will drain your money faster than you can build it.
Types of accounts and their typical minimums
A basic savings account at a traditional bank often has a minimum of $25 to $100. These accounts are straightforward — you deposit money, the bank holds it, and you can withdraw it whenever you need it. The minimum is low because the bank expects many customers to use this account.
High-yield savings accounts, which pay more interest, sometimes require $500 to $2,500. The higher interest rate is the trade-off for a higher minimum. If you have savings you do not plan to touch for a while, this can be worth it — the extra interest might outweigh the minimum requirement.
Money market accounts typically require $1,000 to $2,500 and offer features of both checking and savings accounts. Credit unions often have lower minimums than banks, sometimes zero, because they are member-owned rather than profit-driven.
What happens if you fall below the minimum
The fee appears on your statement as a monthly maintenance charge or minimum balance fee. It is deducted automatically from your account. If your balance is already low, this fee can push you into overdraft — meaning you owe the bank money. Some banks then charge an overdraft fee on top of the minimum balance fee, creating a spiral of charges.
If you fall below the minimum once, you are charged once. If you stay below it for three months, you are charged three times. The fee resets each month, so there is no cap on how many times you can be charged in a year.
Some banks offer a grace period — usually a few days — where you can dip below the minimum without a fee. Others do not. Check your account agreement or call the bank to ask.
How to avoid the minimum balance fee
The simplest way is to choose an account with no minimum. Online banks like Ally, Marcus, and Discover have zero-minimum savings accounts that work exactly like any other savings account. You deposit money, earn interest, and withdraw when you need it — with no monthly fee.
If you already have an account with a minimum, ask your bank if they offer a zero-minimum version. Many do. You can switch to it without closing your current account, though the bank may require you to move your money over.
If you want to stay with your current bank, keep your balance above the minimum. Set a reminder on your phone for the last day of the month to check your balance. If you are close to the minimum, move money in from another account before the bank checks.
Another option is to link your savings account to a checking account at the same bank. Some banks waive the minimum balance fee if you maintain a certain balance in your checking account instead. This works if you keep money in both places anyway.
Minimum balance versus interest rates
A high minimum does not may provide a high interest rate, and a low minimum does not mean low interest. Some zero-minimum accounts pay more interest than accounts with $500 minimums. Compare both numbers before you decide.
Use a calculator to figure out the real cost. If an account requires $500 and charges a $10 fee if you fall below it, but pays 0.01% interest, and another account has no minimum and pays 4.5% interest, the second account wins even if you only have $100 to deposit. The interest you earn will be higher than the fee you would pay.
Banks change their interest rates frequently, sometimes weekly. The minimum balance requirement usually stays the same. When comparing accounts, focus on the minimum you can actually maintain, not the interest rate alone.
Frequently Asked Questions
Does the minimum balance have to be in cash, or can it include pending deposits?
It must be money the bank has already received and cleared. Pending deposits — money you have sent but the bank has not yet processed — do not count. If you are waiting for a paycheck to clear and your balance is below the minimum, you will be charged the fee even though money is on the way.
What if I close my account while I am below the minimum?
You still owe the fee for that month. The bank will deduct it from your remaining balance before they send you the rest. If your balance is lower than the fee, you may owe the bank money after closing.
Can I have a savings account with no minimum at a traditional bank?
Yes, many do. Call your bank and ask if they offer a basic savings account with no minimum balance requirement. You may need to switch to a different account type, but you can stay with the same bank.
If I have multiple savings accounts at the same bank, do they count toward one minimum?
Sometimes. Some banks combine balances across all your accounts; others require each account to meet its own minimum separately. Check your account agreement or ask your bank before opening a second account.
Does a minimum balance requirement protect my money if the bank fails?
No. Your money is protected by the FDIC (Federal Deposit Insurance Corporation) up to $250,000 per account, regardless of the minimum balance. The minimum is about the bank's business model, not your safety.
