# How to calculate pass/fail percentages entered on a spreadsheet?

1. ## How to calculate pass/fail percentages entered on a spreadsheet?

I am trying to set up a spreadsheet with driving test results including one
column to say pass one to say fail and calculate the percentage of each on a
monthly basis. I can enter the info but don't know how to calculate the
percentages  Register To Reply

2. 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 %

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.)
