Counting Non-Blank Cells

You may already know that you can use the COUNTBLANK function to return the number of blank cells in a range. What if you want to count the number of non-blank cells in the same range? One way is to use the COUNTA function, as shown here:

=COUNTA(B1:B13)

The only problem with this formula is that it doesn’t return the complementary value to what COUNTBLANK returns. In other words, the result of COUNTA added to the result of COUNTBLANK doesn’t equal the total number of cells in the original range. The reason for this is that both COUNTBLANK and COUNTA treat formulas different. COUNTBLANK includes, as blank, formulas that return a blank value. COUNTA does not consider such cells blank (even though a blank is returned), so it includes them in its count.

If you consider non-blank cells to be those that are not returned by COUNTBLANK, then you will need to use a longer formula:

=(ROWS(B1:B13)*COLUMNS(B1:B13))-COUNTBLANK(B1:B13)

This formula subtracts the COUNTBLANK result from the total number of cells in the same range.
