The short answer
A MINIMUM BALANCE FEE is charged when your account balance falls below the threshold your bank requires. It is usually 10 to 25 dollars a cycle and is the bank's penalty for dropping under the minimum, not a charge from any merchant.
Why it shows up like this
A MINIMUM BALANCE FEE posts when your daily or average balance dips beneath the floor set for your account type. Banks tie many accounts to a required balance, and if you fall below it at any point in the cycle (or on average across the cycle, depending on the account), the fee is applied. It commonly runs from 10 to 25 dollars and lands on your regular statement date.
This fee overlaps heavily with the monthly maintenance fee, because keeping the minimum balance is often the very condition that would waive the maintenance charge. Some banks list them as one line, others split them. The distinction is that a minimum balance fee is specifically triggered by the balance test, while a maintenance fee is the base charge you avoid by meeting any qualifying condition.
The trigger is usually a single large withdrawal, a bill that cleared before a deposit landed, or an average balance pulled down over the month. Because banks measure the threshold differently, one institution may charge you for a momentary dip while another only looks at the monthly average. The account's disclosure spells out which method applies.

This is your bank's fee for falling under the required balance. Review the lowest point your balance reached during the cycle.
- A large withdrawal or transfer dropped your balance below the minimum, even briefly.
- A bill cleared before an expected deposit posted, lowering your average balance.
- The account requires an average balance you did not maintain across the whole cycle.
- You recently opened the account and the introductory waiver ended.
What to do, in order
Confirm the exact threshold and how it is measured, then keep above it, switch accounts, or ask for a reversal.
- Check the required minimum and how it is measured Your account disclosure states the threshold and whether it is a daily minimum or a monthly average. Knowing which one applies tells you how much cushion to keep.
- Set a balance alert Turn on a low-balance alert a little above the minimum so you get warned before a withdrawal would trigger the fee.
- Move to an account with no minimum Basic and online checking accounts often have no minimum balance requirement. Ask whether you can switch without opening a new account number.
- Ask for a courtesy reversal If a timing mismatch between a bill and a deposit caused the dip, call and request a one-time waiver.
Quick questions
Is a minimum balance fee the same as a maintenance fee?
They are closely related. Meeting the minimum balance is usually the condition that waives the monthly maintenance fee. Some banks combine them into one line; others charge a distinct minimum balance fee triggered only by the balance test.
How do I stop getting charged a minimum balance fee?
Keep your balance above the required threshold, set a low-balance alert just above it, or switch to an account that has no minimum requirement. If a delayed deposit caused a one-time dip, ask your bank to reverse the fee.
