SUMX Function (DAX)
Returns the sum of an expression evaluated for each row in a table.
SUMX(<table>, <expression>)
Parameters
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
A number (R8).
Remarks
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.
Only the numbers in the column are counted. Blanks, logical values, and text are ignored.
To see some more complex examples of SUMX in formulas, see ALL Function (DAX) and CALCULATETABLE Function (DAX).
Example
The following example first filters the table, InternetSales, on the expression, ShippingTerritoryID = 5, and then returns the sum of all values in the column, Freight. 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.
