excel - How do I count the number of times a value with a certian criteria occurs within an conditional index of cells -


i have below formula works great find percentage looking for:

=sum((countif(b12:b10002,">=9"))/(count(b12:b10002)))

what need count , countif make range conditional preceding column.

  • range a12:a10000 indicates date
  • range b12:b10000 indicates number between 1-10
  • cell a5 indicates date

i know how many times 9 or 10 occurs in b12:b10000, if preceding cell in a12:a10000 equal a5

i have tried index match, renders "1" (meaning true) or gives me number 10 first cell in b12

any appreciated! :)

you can use countifs() this. countif accept multiple criteria:

=countifs(a12:a10000,a5,b12:b10000,">=9")

if using older version of excel doesn't support countifs() can use sumproduct() instead:

=sumproduct((a12:a10000=a5)*(b12:b10000>=9)*1)
