Daily DAX : Day 328 CLOSINGBALANCEMONTH

Power BI DAX: CLOSINGBALANCEMONTH Function

Description

The CLOSINGBALANCEMONTH function in Power BI DAX (Data Analysis Expressions) calculates the value of an expression at the end of a specified month, considering a given date column and filter context.

Syntax

CLOSINGBALANCEMONTH(<expression>, <dates>[, <filter>])

• <expression>: The value to evaluate (e.g., sum of sales).
• <dates>: A column containing date values, typically from a Date table.
• <filter>: (Optional) A filter expression to apply to the calculation.

Return Value

The value of the expression at the last date of the month within the filter context.

Use Case

CLOSINGBALANCEMONTH is commonly used in financial and time-based analysis to determine the balance or total of a measure (e.g., inventory, account balance, or sales) at the end of each month. It is particularly useful for:

• Tracking month-end balances for accounts or inventories.
• Reporting cumulative totals at the end of a month.
• Analyzing trends by comparing month-end values over time.

Example

Suppose you have a table Sales with columns Date, Amount, and a related DateTable. To calculate the total sales at the end of each month:

MonthlyClosingSales = 
CLOSINGBALANCEMONTH(
    SUM(Sales[Amount]),
    DateTable[Date]
)

This measure returns the total sales for the last day of each month based on the DateTable[Date] column.

Notes

• Requires a valid date column in a proper Date table for accurate results.
• Sensitive to the filter context; ensure proper filtering to avoid unexpected results.
• Only considers data up to the last date in the month within the filter context.
