How to set up weighted average for multiple years

[minhquankhong]

I have set up measures to get the percentage of total foreign sales over total gross income for 2007 - 2013. However, I do not know how to set up the weighted averages. Below are examples of my questions and weighted averages. These weighted averages need to be in the same dashboard. Thank you for your help.

2007 86%

2008 87%

2009 89%

2010 90%

2011 91%

2012 92%

2013 88%

Weighted average 1 = (2007+2008+2009)/(2007+2008+2009)

Weighted average 2 = (2008+2009+2010)/(2008+2009+2010)

Weighted average 3 = [(2009+2010)/(2009+2010)]*2/3 + [2011/2011]*1/3

Weighted average 4 = [2011/2011]*1/3 + [(2012+2013)/(2012+2013)]*2/3

Hi， @minhquankhong 

It’s my pleasure to answer for you.

According to your description,I think you can create four measures to calculate the desired result.

Like this:

weighted average4 = var a=CALCULATE('Measures 1'[% of AFBI/Total Income],'PL_Domestic Entitiies'[Year]="2011")
var aa=CALCULATE('Measures 1'[Total AFBI],'PL_Domestic Entitiies'[Year]="2011")
var b=CALCULATE('Measures 1'[% of AFBI/Total Income],'PL_Domestic Entitiies'[Year]="2012")
var bb=CALCULATE('Measures 1'[Total AFBI],'PL_Domestic Entitiies'[Year]="2012")
var c=CALCULATE('Measures 1'[% of AFBI/Total Income],'PL_Domestic Entitiies'[Year]="2013")
var cc=CALCULATE('Measures 1'[Total AFBI],'PL_Domestic Entitiies'[Year]="2013")
return DIVIDE(c*cc+b*bb,c+b)*DIVIDE(2,3)+DIVIDE(a*aa,a)*DIVIDE(1,3)

Here is my sample .pbix file.Hope it helps.

If it doesn’t solve your problem, please feel free to ask me.

Hi Janey,

Sorry for the late reply. I was out of the office last week and in training the whole time this week. I tested your solution. It worked. Thank you so much for your help.

@minhquankhong , the same data does seem to be inline with what you are asking

Can you share sample data and sample output in table format? Or a sample pbix after removing sensitive data.
