What counts as your minimum balance
A minimum balance is the lowest amount of money a bank requires you to keep in your savings account at all times to avoid a monthly fee. The exact amount varies by bank and account type — some accounts have no minimum at all, while others require $25, $100, $500, or more. Your bank's fee schedule, which you can find online or ask for in person, will state the minimum for your specific account.
The bank checks your balance on a specific day each month, usually the last day of the month or the day your statement closes. If your balance falls below the minimum on that day, the bank charges you a fee — typically $5 to $15 — even if you had enough money earlier in the month. Some banks look at your average daily balance over the month instead, which gives you a little more flexibility if you dip below the minimum for a few days.
Not all savings accounts have minimums. Many online banks and credit unions offer savings accounts with zero minimum balance requirements. If you carry a low balance or want to avoid the risk of a fee, these accounts are worth comparing to traditional bank options.
Key Takeaways
- Minimum balance requirements range from zero to $500 or more, depending on the bank and account type.
- The bank checks your balance on a set day each month, usually the last day or statement close date, and charges a fee if you fall short.
- Some banks measure your average daily balance over the month instead of a single-day snapshot, which can help you avoid fees.
- Online banks and credit unions often have no minimum balance requirement, making them a good choice if you keep a small savings balance.
How the minimum balance is measured
Banks use one of two methods to check whether you meet the minimum. The first is a point-in-time balance, which looks at your account on a single day — usually the last calendar day of the month or the day your statement closes. If you have $450 in the account on that day but the minimum is $500, you owe the fee, even if you had $600 the day before.
The second method is average daily balance. The bank adds up your balance at the end of each day for the entire month, then divides by the number of days. If your average comes out below the minimum, you pay the fee. This method is more forgiving because a few days of low balance won't trigger a fee if you recover by month's end. Ask your bank which method your account uses — it's in your account agreement or fee schedule.
When the minimum balance fee gets charged
The fee appears on your statement as a monthly maintenance fee, service charge, or minimum balance fee — the name varies by bank. It usually posts on the last day of the month or within a few days after your statement closes. Once the fee is charged, it reduces your account balance further, which can create a cycle: you fall short of the minimum, pay a fee, fall even further short, and pay another fee the next month.
Some banks waive the minimum balance requirement if you meet other conditions. Common waivers include setting up direct deposit of your paycheck, maintaining a linked checking account, or keeping a certain balance in a different account at the same bank. Check your account agreement to see what waivers are available — you may already may have access to for one without realizing it.
Comparing minimums across account types
Traditional savings accounts at brick-and-mortar banks often have minimums of $100 to $500. High-yield savings accounts, which pay more interest, sometimes have higher minimums — $1,000 to $2,500 — because they're marketed to people with larger balances. Money market accounts typically have the highest minimums, often $2,500 or more.
Online banks and credit unions tend to have lower or no minimums because they have fewer physical branches and lower operating costs. If you're comparing accounts, look at the total cost to you: a high-yield account with a $1,000 minimum and a $10 fee might cost you more than a low-rate account with no minimum if you can't maintain that balance consistently.
| Account Type | Typical Minimum | Fee if Below Minimum |
|---|---|---|
| Traditional savings (bank) | $100–$500 | $5–$15/month |
| Online savings | $0–$100 | $0–$5/month |
| High-yield savings | $500–$2,500 | $5–$15/month |
| Money market account | $2,500–$10,000 | $10–$25/month |
| Credit union savings | $0–$100 | $0–$5/month |
How to avoid minimum balance fees
The simplest approach is to keep your balance above the minimum at all times. If your account requires $250 and you typically have $300, you have a $50 cushion. But if you're living paycheck to paycheck or your balance fluctuates, this may not be realistic.
A second option is to move to an account with no minimum. Many online savings accounts have zero minimums and pay competitive interest rates. The trade-off is that you can't walk into a branch to deposit cash or speak to a teller in person — everything happens online or by mail.
A third option is to meet a waiver condition. If your bank waives the minimum for direct deposit, set up your paycheck to deposit automatically. If they waive it for a linked checking account, open one and keep it active. These steps take a few minutes and can save you $60 to $180 per year in fees.
If you've already paid a minimum balance fee, contact your bank and ask if they will reverse it. Many banks will reverse one or two fees per year as a courtesy, especially if you've been a customer for a while or if you explain that you didn't understand the requirement.
What happens if you can't maintain the minimum
If you know you can't keep the minimum balance, close the account and move your money to one with no minimum. There's no penalty for closing a savings account — you simply withdraw your balance and the account is closed. Your bank may ask why you're leaving, but you're not obligated to explain.
Before you close, check whether you have any pending transactions or automatic transfers linked to the account. If you have a savings goal or emergency fund, even a small balance in a no-minimum account is better than paying monthly fees that eat into your savings.
Frequently Asked Questions
Can a bank charge a minimum balance fee if my balance drops below the minimum for only one day?
It depends on how your bank measures the minimum. If they use a point-in-time balance and that one day is the measurement day (usually the last day of the month), yes, you'll be charged. If they use average daily balance, one low day usually won't trigger a fee. Check your account agreement to see which method applies to you.
Does the minimum balance include money in linked accounts?
No. The minimum balance requirement applies only to the specific account you're being charged for. Money in your checking account, money market account, or other savings accounts at the same bank does not count toward the minimum for your savings account. However, some banks waive the minimum if you maintain a certain balance in a linked account — that's different from counting it toward the minimum.
What if I'm a minor or a student — do I have to meet the same minimum?
Many banks offer student or youth savings accounts with lower or no minimums. These accounts are designed for people under 18 or 25, depending on the bank. If you're in that age group, ask your bank whether you may have access to for a student account, which typically has better terms than a standard savings account.
If I close my account, do I lose the interest I've earned?
No. Interest you've already earned stays in your account and is paid to you when you withdraw your balance. Interest is calculated and posted monthly or quarterly, so if you close mid-month, you'll receive interest through the last day you held the account.
Can a bank change the minimum balance requirement without telling me?
Banks must notify you of changes to account terms, usually by mail or email, and typically give you 30 days' notice. If your bank raises the minimum and you can't meet it, you have the right to close the account without penalty during that notice period. Check your email and mail for account update notices so you don't miss the deadline.
