What is Average Account Balance?

How to Calculate Average Account Balance

The calculation involves summing all individual account balances and then dividing by the total number of accounts. Here's the step-by-step process:

Identify all accounts within the time period
Record the balance for each account at the end of the period
Sum all account balances to get the total
Divide the total by the number of accounts

Average Account Balance = (Sum of all account balances) / (Number of accounts)

Example Calculation

Consider a bank with 5 accounts with the following balances at month-end:

Account	Balance ($)
Account 1	1,200
Account 2	3,500
Account 3	800
Account 4	2,100
Account 5	1,400
Total	9,000

Using the formula:

Average Account Balance = (1,200 + 3,500 + 800 + 2,100 + 1,400) / 5 = 9,000 / 5 = $1,800

The average account balance for this bank is $1,800.
