SUMPRODUCT
Multiplies corresponding elements across one or more ranges, then adds up the results.
Compatibility: All Excel versions
Syntax
=SUMPRODUCT(array1, [array2], ...)
Example
=SUMPRODUCT(A2:A10,B2:B10)
When to Use It
Use SUMPRODUCT to calculate something like total revenue from separate Quantity and Price columns in one formula, without needing a helper column — or to build conditional sums/counts using array logic beyond what SUMIFS can do.
