Dave, Thanks for your response. No, I do not have the data. I need t
know how to save a formula so others can put in there data an
immediately get the answer to the equation. Any thoughts? :confused

Maybe something like this in a separate helper column (my test data was in
G1:G20):

=IF(G1>PERCENTILE($G$1:$G$20,0.9),"Top 10%","")

And drag down.

then filter on that column to show just the top 10%.
