The contribution margin is $48 for each unit.
The contribution margin per unit is calculated as the selling price of a product divided by the variable manufacturing costs. The contribution margin per unit is the amount that each sale makes toward paying fixed costs. Once the fixed costs have been covered, the profit per unit sold will be displayed.
The margin of contribution per unit = Selling price - Variable cost per unit
Variable cost:
Selling commission = 4120 × 10%
= $12
Variable manufacturing cost = $60
Total variable cost = $12 + $60
= $72
Margin of contribution per unit = $120 - $72
= $48
