Average Daily Balance & Savings Accounts Explained:

Accompanying the beginning balance, and the ending balance, that of the average daily relates to a deposit account where the total daily deposit balances for a given monthly period are divided by the number days in the period. Since statements typically run with begining and ending balances that occur during ongoing month's, and not by calendar-month start and end dates, the number of days during statement periods do seem to vary and may not correspond with the number of days in the month when the statement is received.

Taking the uncollected amounts into account, the average collected balance is yet more specific in regards to account activity. While the average daily float describes items in collection.
