The minimum daily balance in banking is the minimum amount on the balance that the bank requires from the account owner, that they should have each day to avoid charging a maintenance fee. The minimum daily balance is a different thing from the average daily balance, which is calculated as the sum of daily balances in a given period divided by the number of days. If it happens that the daily balance falls below the minimum amount required, and payment is made to the account on the same day, the bank will not charge a fee for the service. Otherwise, if the minimum daily balance falls below the minimum, a maintenance fee is charged.
On some accounts, there is a minimum daily balance required in order to avoid a monthly maintenance fee. If your account falls below the required minimum, the maintenance fee would be assessed on the last day of your statement cycle. The fee applied depends on your account type.
