3 variable product - contribution analysis

Postby Guest » Mon Nov 11, 2019 2:34 am

There are 3 variables (X/Y/Z).

Each of them change from X1 to X2 / Y1 to Y2 and Z1 to Z2. Hence the change in the product is (X2*Y2*Z2 - X1*Y1*Z1). how much did each factor contribute in the delta.

E.g.

X changes from 30 to 40
Y changed from 40% to 50%
Z changes from 100 to 110

the product XYZ changes from (30 * 40% * 100 = 1,200) to (40 * 50% * 110 = 2,200) - thus the product increases by 1,000.

How much did X contribute in the increase, Y contribute in the increase and so on. Can someone try and solve this - thanks .
