## Calculate an average from a Sum by Month

Hi Guys,

I want the average from a time Period.

In one Table i have 2 Rows like this:

Date:                  Values:

01.01.2016        100

01.01.2016        50

01.01.2016        10

01.02.2016        50

01.02.2016        50

01.02.2016        20

If i creat visuals with average i only get the full average of all data ( 46,6666)

but i need it per Month  '
average  01/2016 = 53,33

02/2016 = 40

I tryed a lot of things with the little DAX i know but nothing worked out correctly.

Hi Mertsch,

I have tested it on my local environment, you can add calculated column to display the month name using the DAX below
Month = MONTH(MonthAverage[Date])

And then create a measure
MeasureAverage = SUM(MonthAverage[Total])/DISTINCTCOUNT(MonthAverage[Month])

I have the quantity of employee per month, need to calculate the average per month

Final Qty                  Average per month

January :100            100

March:   90               105

April ::  100               95

Average= (Qty 1+Qty)/2

what i need is:

the final average:

01/2016 = Sum 160

02/2016 = Sum 120

Try creating a calculated column like:

`Month = MONTH([Date])`

Looks like you want to get the average by Summing the amount and dividing it by the number of months/distinct dates rather than dividing by the number of rows.

This might help, write following DAX measures:

Amount=SUM([Values])

NumOfDistinctDates=DISTINCTCOUNT([Date])

Avg=DIVIDE([Amount],[NumOfDistinctDates])

Hey,

I have one more question here, i ahave one Power Bi template, which has Hours by month Operating Group wise.

Cureently in Power Bi i am using Matrx visual for this and i have the data from February 2018 to December 2018, i .e for 10 months.

But when i used the formual

Average Hours = SUM('MC Payroll and Hours'[Hours]) / DISTINCTCOUNT('Dates'[Month].[Month])

For
DISTINCTCOUNT('Dates'[Month].[Month])    it was taking months count as 12 not 10, is there any way that i can write code for taking only 10 months.(of visual has 10 months data, months count should come to 10, if visual has data for 8 months, count should come to 8.)

My Financial Year is September to Aug.

thanks.

well it wokrs for the full tabel but if i used filters it dont work for it.

( 140 is correct for all data )

But after using Filters it will be still 140.  it need to be 60 in that case

There must be a other way to have it more flexible with using filters

The data need to be calculated acording to the used filters and visual in front end.

May it works with GROUPBY Month Dates?! But i dont get the DAX work

= GROUPBY (Tabelle1;Tabelle1[Month];“TEST2”;SUM(CURRENTGROUP();Tabelle1[Total]))

This does not work if the data covers a period longer than a year as multiples will appear over multiple years, is there another way?

substitute the followign for the month formula:  =format([date], "YYYYMM")

Hi,

I am a beginner in Power BI. I want to arrive at % of surgeries performed by each doctor for the month. i. e. total surgeries by a doctor in a month DIVIDED BY total surgeries in the month.

When I used the solution in a measure as "MonthlySurgeries = sum(tblReportPaed[Surgeries])/DISTINCTCOUNT(tblReportPaed[MonthNumber])" it generates an error at the bottom of the screen which reads as "TABLE: tblReportPaed (92 Rows) COLUMN: Measure (0 distinct values)".

Where am I going wrong?

Hi,

What if we want to use this measure with a date drill down, how would it work?
