How to calculate average balance in bank account

To calculate the average balance in your bank account, you typically find the Monthly Average Balance (MAB). This is calculated by adding the closing balance of each day in a month and dividing the total by the number of days in that month. To maintain this balance effectively:

• Add the end-of-day balances for all days in the month.
• Divide the sum by the total number of days (28, 30, or 31).
• Ensure the result meets your bank's minimum requirement to avoid non-maintenance charges.
