How to calculate pass/fail percentages entered on a spreadsheet?
Hi I've just assumed the pass and fails are in Col A. I then put this formula in B1 to Count the number of passes and divide by the number of Pass or Fails =SUMPRODUCT(--($A$1:$A$1000="*pass*"))/COUNTA(A:A) Same formula to find Fails =SUMPRODUCT(--($A$1:$A$1000="*fail*"))/COUNTA(A:A) Then Format cells as % VBA Noob -- VBA Noob ------------------------------------------------------------------------ VBA Noob's Profile: http://www.excelforum.com/member.php...o&userid=33833 View this thread: http://www.excelforum.com/showthread...hreadid=568630 |

I don't think that wild cards will work like that.
But if Pass (or Fail) is the only word in the cell: =SUMPRODUCT(--($A$1:$A$1000="fail"))/COUNTA(A:A) will work ok. And if pass and fail are included in longer strings: =SUMPRODUCT(--ISNUMBER(SEARCH("fail",$A$1:$A$1000)))/COUNTA(A:A) will look within each cell. (Similar formulas for Pass.)
