Step by step
- 1In a new column, enter =A2*B2 and copy it down for a row-by-row product.
- 2To total every row’s product at once, use =SUMPRODUCT(A2:A100, B2:B100).
- 3SUMPRODUCT multiplies the ranges pairwise and sums the result.
Tips
- The two ranges in SUMPRODUCT must be the same size or it returns #VALUE!.
- SUMPRODUCT can also count with conditions, e.g. =SUMPRODUCT((A:A="X")*1).
