## Divide By Number of Months YTD

I want to divide by total inventory by the number of months YTD.   The count function gives me all of the months in my calendar table.  How do I filter it just for the current year that will be a filtered selection?    Example:  So if my data is through May, it will divide by 5.

Averge Inventory = DIVIDE(CALCULATE([Inventory], DATESYTD(d_DateTable[Date])), COUNT(d_DateTable[Month]))

I researched forums and tried a dozen different fomulas.  Sorry, I am beginner.

Hi @bhorvati,

I'm assuming your calendar table is related with your inventory table.

Create a month column on your inventory table then change your measure to:

```Average Inventory_distinct_Count =
DIVIDE (
CALCULATE ( [Inventory]; DATESYTD ( d_DateTable[Date] ) );
MAX('Table'[Month_])
)```

When you divide the number by count you will get every single row so in January you will get 31 days, you need to get the distinct number of that month in this case I have it by the MAX formula of the inventory table:

Try this

Months YTD =  totalytd(countrows(values(d_DateTable[Month])),d_DateTable[Date])

Hi @bhorvati,

Instead of COUNT use DISTINCTCOUNT should work as you need.

Hi @MattAllington Solution provided, returned a month count of 12 when my data is through May, thus i need the count to be 5.   The only page filter I have on is year.

By the way, I've been watching your videos on YouTube.  Thanks sharing all the content and advice.

@MFelix  Thank your for your reply, but can you look at my formula and see if you can see what I am doing wrong.   My formula is still picking up the MAX month in the date table which is 12.

Hi @bhorvati,

The division must be made by the MAXIMUM month in you inventory table not the dste table.

@MFelix   I finally got it.   I have been having the same issue with a barrels per day formula.  I've been having to filter every report page for month to get my reports to work correctly.  This has been a HUGE help.  Thanks for taking the time.  Much appreciated.
