A Â Â ([tex]\text{Direct material per unit}[/tex]) Â Â Â Â Â Â Â Â Â $ 24 Â Â Â Â $ 15 Â Â Â $9
B Â Â (Material cost per pound) Â Â Â Â Â Â Â Â $3 Â Â Â Â Â Â $3 Â Â Â $3
C=A/B (pound of material per unit) Â Â Â Â Â 8 Â Â Â Â Â Â 5 Â Â Â Â Â 3
D Â (Contribution margin per unit) Â Â Â Â Â $32 Â Â Â Â $14 Â Â Â $21
E=D/C (Contribution margin pound    $ 4      $ 2.8   $ 7
      of raw materials)
Order of preference to allocate material  2nd   3rd    1st
Since the product C has maximize 'contribution margin per pound' it will give 1st preference, followed by the product A and B.
The allocation of the available 5000 pounds of the raw material.
                                  A        B        C
Maximize units that can be sold (A) Â Â Â Â 1000 Â Â Â Â 1000 Â Â Â Â 1000 Â
Materials required per unit (B) Â Â Â Â Â Â Â Â Â 8 Â Â Â Â Â Â Â Â 5 Â Â Â Â Â Â Â Â 3
Total material requirement (C) Â Â Â Â Â Â Â Â 8000 Â Â Â 5000 Â Â Â Â 3000
Available raw material in pounds       5000 pounds
(-) first allocation to product C Â Â Â Â Â Â Â Â Â 3000 pounds
Remaining material                   2000 pounds
(-) seconds allocation to product A Â Â Â Â Â 2000 pounds
Remaining for the product B Â Â Â Â Â Â Â Â Â Â Â Â 0 pounds
Now calculating the total contribution on the above allocation basis.
                                A      B          C       Total
Material allocated to A(pounds) Â Â Â 2000 Â Â Â Â 0 Â Â Â Â Â Â Â Â 3000 Â Â Â 5000
Contribution per pound (B) Â Â Â Â Â Â Â Â $ 4 Â Â Â Â $2.8 Â Â Â Â Â Â Â Â $7
Total contribution margin (AxB) Â Â Â $8000 Â Â $0 Â Â Â Â Â Â Â $21000 Â Â $29,000
Therefore, the total contribution margin is $29,000.
