Evaluates an expression for each row of a table and returns the largest value.




Term Definition
table The table containing the rows for which the expression will be evaluated.
expression The expression to be evaluated for each row of the table.

Return value

The largest value.


  • The table argument to the MAXX function can be a table name, or an expression that evaluates to a table. The second argument indicates the expression to be evaluated for each row of the table.

  • Of the values to evaluate, only the following are counted:

    • Numbers
    • Texts
    • Dates
  • Blank values are skipped. TRUE/FALSE values are not supported.

  • This function is not supported for use in DirectQuery mode when used in calculated columns or row-level security (RLS) rules.

Example 1

The following formula uses an expression as the second argument to calculate the total amount of taxes and shipping for each order in the table, InternetSales. The expected result is 375.7184.

= MAXX(InternetSales, InternetSales[TaxAmt]+ InternetSales[Freight])  

Example 2

The following formula first filters the table InternetSales, by using a FILTER expression, to return a subset of orders for a specific sales region, defined as [SalesTerritory] = 5. The MAXX function then evaluates the expression used as the second argument for each row of the filtered table, and returns the highest amount for taxes and shipping for just those orders. The expected result is 250.3724.

= MAXX(FILTER(InternetSales,[SalesTerritoryCode]="5"), InternetSales[TaxAmt]+ InternetSales[Freight])
