Average calculation in same column but for different values

Hello everyone,

I'm trying to calculate the average of some different values in the same column. And after that, using that result to divide another value in the same column, resulting a value in porcetage.

 

The example of the table and the equation are shown below:

tablebi.PNG


For ID CODE 41:            X =[ 10 / (20+5/2) ] - 1
                                               |        |    |
TYPE-------------->               A       B   C -> media between B and C


I really appreciate for the help.

Thank you for the answer. It helpde me a lot.

I just needed to change little things to adapt on my need, but your answer was fundamental. 

Best wishes!

Not sure I follow this, but if you want the average of each ID CODE, for example, you could do this:

 

New Column = AVERAGEX(FILTER('Table',[ID CODE] = EARLIER([ID CODE])),[Value])
