Calculating an Average based upon a value in other column

I have a calculation to calculate the number of days between two columns.

=IFERROR(NETWORKDAYS([Date Submitted]41, [Go Live Date]41), " ")  It works great to return a blank if the customer has not gone live.

Then I have formula to calculate the average of the cells.

=AVG([Number of Days to Implement]12:[Number of Days to Implement]41)  Also works great !

I now want to calculate the average based upon a region (EAST, WEST, CENTRAL, MOUNTAIN)

I tried this formula but it is not working.

=AVG([Number of Days to Implement]12:[Number of Days to Implement]41, [US Region]:[US Region], "Central")

Any suggestions?

    smartsheet does not currently have an avgif formula. I recommend submitting a product enhancement request in the bar to the right.

    That said, you can achieve the same results by using a sumif()/Count()


    =sumif([US Region]12:[US Region]41, "Central",Number of Days to Implement]12:[Number of Days to Implement]41)/Count([US Region]12:[US Region]41)

    You could also use an AVG(COLLECT( formula which works exactly how an AVGIFS would work.


    =AVG(COLLECT([Number of Days to Implement]12:[Number of Days to Implement]41, [US Region]:[US Region], "Central"))

  • Thank you to both for your assistance.  The average days were not calculating correctly with the formula but I was able to make a slight adjustment based upon another calculation I have in my sheet.

    I already had it calculating the total number of closed implementations.

    =COUNTIFS([US Region]:[US Region], "East", Closed:Closed, "Yes")

    So I used that cell to do the division and it worked perfectly.

    =SUMIF([US Region]15:[US Region]44, "East", [Number of Days to Implement]15:[Number of Days to Implement]44) / COUNT([After Hours]2)

    After Hours is the column name I have for the COUNTIF formula

    Glad you were able to find a working solution! yes

  • Hi Kandee,

    This may help in the future:

    =AVERAGEIF(range, criteria, [average_range])    

    Returns the average of cells that meet a given criteria.

    Example: =AVERAGEIF([Value 1]200:[Value 2]280, >100)

    Kara, when was this added? i double checked the formula list and even checked it in a blank sheet to make sure that averageif wasn't a function yet when i posted. I also checked the release notes and there is no mention of it

    It was added yesterday, or at least I noticed it yesterday.

    There are a lot of new functions.

    Heres more info about AVERAGEIF:

    Hope that helps!

    Have a fantastic day!
