Count cells not equal to x or y

Generic formula 

=COUNTIFS(rng,"<>x",rng,"<>y")

Explanation 

To count cells not equal to this or that, you can use the COUNTIFS function with multiple criteria.

In the example shown, there is a simple list of colors in column B. There are 6 cells total with a color, and a few are duplicates.

To count the number of cells that are not equal to "red" or "blue", the formula in E6 is:

=COUNTIFS(rng,"<>red",rng,"<>blue")

In this example "rng" is a named range that equals B6:B11.

How this formula works

The COUNTIFS function counts cells that meet one or more conditions. All conditions must pass in order for a cell to be counted.

The key in this case is to use the "not equals" operator, which is <>.

To add another criteria, simply add a another range / criteria pair of arguments.

Alternative with SUMPRODUCT

The SUMPRODUCT function can also count cells that meet multiple conditions.

For the above example, the syntax for SUMPRODUCT is:

=SUMPRODUCT((rng<>"blue")*(rng<>"green"))
