How to Calculate Age from a Specific Date & Average Results

I am trying to average the age of multiple events as of specific dates (end of each month).

Currently I have "Age" calculated from "Today()" in a column in another sheet. I would like to instead calculate the Age from "Date of Notification" to "End Date", and would like to avoid using a helper column to do so. I do not want to change the "Age" column I currently have or create another age calculation helper column.

AVG(
      COLLECT(
              {Age}, 

              {Status}, 
              @cell <> "Complete", 
              {Date of Notification}, 
              @cell <= [End Date]@row
     )
)

What do you currently have in your Age column? Are you able to provide some screenshots for context?

Currently the Age column is on a separate sheet and calculates the total age/duration of each event (to the day it was closed or to today if still open). Unfortunately, I can't easily provide a screenshot.

I understand it is on a separate sheet and does a calculation, but what is the formula you currently have in the Age column?

Ah, sorry: Here is the formula:

=IFERROR(NETDAYS([Date of Notification]@row, IF([Status]@row = "Complete", IF([Step 2 Closure Date]@row = "", [Step 1 Closure Date]@row, [Step 2 Closure Date]@row), TODAY())), "")

Unfortunately you are going to need to keep the helper column on the source sheet in this instance.

When you say keep the helper column, you mean create a new one? If I were to do that, would I need a new helper column for each progressive month? I'm trying to show monthly metrics where it has the average age of incomplete events calculated at the end of the respective month.
