Percentile rank of a cell that isn't in an array - EXCEL

Question

I have an array of numbers and would like to see what percentile another cell would be in if it was included in that array. I can't directly do the RANK function because the cell I'm testing isn't in the array. There's a number of cells I'm looking to find the percentile rank for as well.

Perhaps there's a way to select an array AND a separate cell to be included in the Rank function?

Answer 1

You could try using a union of ranges in the second argument of the RANK function, for example:

 =RANK(B1,(A1:A4,B1),1)

If numbers are on a different sheet another option is:

 =COUNTIF(Sheet1!A1:A4,"<"&B1)+1
