DAX formula for weighted average

[erimaz]

Hello,

I am looking for the correct forumla to calculate weighted value over hundreds of records.

Given just a few records, the weighted Gross profit % average for the following items would be: ((100*0.1)+(20*0.3)+(40*0.2))/(100+20+40)

Item Value	Gross Profit %
100	10
20	30
40	20

Given hundreds of values, is there a DAX formula that allows to multiply only values on the same row, and therefore achieve the weighted average I am looking for?

Many thanks in advance for youir support!!!

@erimaz , if they are columns

divide(sumx(Table,Table[Item Value]* Table[Gross Profit %]), sum(Table[Item Value]))
