The $C2:$C13 for the COUNTIF should actually be the selection for the entire set of computed month. 
In my example, it should really be $C2:$C3.



| tool   | start date      | computed month |   |   month | count                     |
|--------+-----------------+----------------+---+---------+---------------------------|
| drill  | Sept 15, 2019   |        2019-09 |   | 2018-10 | =COUNTIF($C$2:$C$13, E2)  |
| hammer | October 8, 2018 |        2018-10 |   | 2018-11 | =COUNTIF($C$2:$C$13, E3)  |
|        |                 |                |   | 2018-12 | =COUNTIF($C$2:$C$13, E4)  |
