Try...

=SUMPRODUCT(SUBTOTAL(3,OFFSET(E2:E40,ROW(E2:E40)-ROW(E2),0,1)),--(E2:E40=
"Yes"))/SUBTOTAL(3,E2:E40)

Hope this helps!

I have a table of data converted into a dropdown list that contains a
few columns with just "yes" or "no" entries. I created a formula below
the actual blue border of the list to calculate the percentage of yes'
in the list:
=COUNTIF(E2:E40,"Yes")/(COUNTIF(E2:E40,"Yes")+COUNTIF(E2:E40,"no"))

However, this only calculates the data for the entire list, even when I
have filtered it. How do I modify it to apply only to the filtered
entries in the list? Thanks if you can help, guys.
