Many of the most common spreadsheet questions involve counting and summing values and
other worksheet elements. It seems that people are always looking for formulas to count
or to sum various items in a worksheet. If I’ve done my job, this chapter answers the vast
majority of such questions. It contains many examples that you can easily adapt to your own
Counting and Summing Worksheet Cells
Generally, a counting formula returns the number of cells in a speciﬁ ed range that meet certain criteria.
A summing formula returns the sum of the values of the cells in a range that meet certain criteria.
Table 17.1 lists the Excel worksheet functions that come into play when creating counting and
summing formulas. Not all these functions are covered in this chapter. If none of the functions in
Table 17.1 can solve your problem, it’s likely that an array formula can come to the rescue; refer to
Excel’s Help to learn more about array formulas.
If your data is in the form of a table, you can use i ltering to accomplish many counting and summing operations. Just
set the i filter criteria, and the table displays only the rows that match your criteria (the nonqualifying rows in the table
are hidden). Then you can select formulas to display counts or sums in the table’s total row. Chapter 19 introduces
