Answer:
1. Contribution margin (Per unit) = $80
2. Contribution rate (Ratio) = 66.67%
Explanation:
Requirement 1:
Given, Price (Painting) = $120
Variable costs (Brush and Paint) = $40
We know, contribution margin refers to the differences between selling price and variable costs. It is one of the most significant parts of management accounting to make a productive decision.
Contribution margin (Per unit) = Selling price - Variable Cost
Contribution margin (Per unit) = $120 - $40
Contribution margin (Per unit) = $80
Requirement 2:
Contribution margin ratio is the percentage of sales revenue or selling price remaining after deducting all the variable expenses or costs. The rate is calculated by dividing the contribution margin by sales.
Contribution Margin Rate (Ratio) = (Contribution Margin / Selling Price)*100
C.M Rate (Ratio) = ($80 / $120)*100
C.M Rate (Ratio) = 66.67%
The contribution margin analysis is an important piece of the break-even analysis.
