expression The expression to be evaluated for each row of the table.

Return value

A decimal number.


  • The SUMX function takes as its first argument a table, or an expression that returns a table. The second argument is a column that contains the numbers you want to sum, or an expression that evaluates to a column.

  • The SUMX is an iterator function.

  • Only the numbers in the column are counted. Blanks, logical values, and text are ignored.

  • For more complex examples of SUMX in formulas, see ALL and CALCULATETABLE.

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


The following example first filters the table, InternetSales, on the expression, 'InternetSales[SalesTerritoryID] = 5`, and then returns the sum of all values in the Freight column. In other words, the expression returns the sum of freight charges for only the specified sales area.

= SUMX(FILTER(InternetSales, InternetSales[SalesTerritoryID]=5),[Freight])  

If you do not need to filter the column, use the SUM function. The SUM function is similar to the Excel function of the same name, except that it takes a column as a reference.
