Percentage of a percentage?

[davidmg1982]

I better explain this right, i would like to present in a cascade chart the participation of a category in the percentage fraction out of goal. Any guide will be highly appreciated.

From the table below in PowerBI I have the following:

On Goal = 8/18 = 44%

What i would like to present is the percentage result in each step of the cascade are the following, to understand which category has the bigger impact in the out of goal fraction:

Categories
A = (2/18) = 11%
B = (1/18) = 6%
C = (3/18) = 17%
D = (2/18 = 11%
Total bar = 44%
