MS Excel: SUMPRODUCT Function (WS)

Learn how to use the Excel SUMPRODUCT function with syntax and examples.


The Microsoft Excel SUMPRODUCT function multiplies the corresponding items in the arrays and returns the sum of the results.


The syntax for the Microsoft Excel SUMPRODUCT function is:

SUMPRODUCT( array1, [array2, ... array_n] )

Parameters or Arguments

  • If all arrays provided as parameters do not have the same number of rows and columns, the SUMPRODUCT function will return the #VALUE! error.
  • If there are non-numeric values in the arrays, these values are treated as 0's by the SUMPRODUCT function.
