Zovo Average Balance

Average monthly balance from a bank statement, every calendar day counted.

Zovo Average Balance is an average monthly balance calculator for bank statements. Give it the transactions with the running balance (or an opening balance) and it works out the end-of-day balance for each calendar day, carrying it forward over weekends and quiet days, then the day-weighted average for each month and for the whole period. It checks each printed running balance against the arithmetic and lists the rows that differ, finds the lowest and highest daily balance with their dates, month-end balances, credits and debits per month, recurring salary-like credits and large one-off deposits. You get an Excel workbook with a row for each day and a 1-page PDF summary to add to a visa, proof of funds or loan file.
