Answer for screen readers
The contribution margin per unit is calculated by subtracting the variable cost per unit from the selling price per unit.
Steps to Solve

Identify the selling price per unit
Determine the amount for which one unit of the product is sold. Let's denote this as $P$.

Identify the variable cost per unit
Determine the variable cost associated with producing one unit. Let's denote this as $V$.

Apply the contribution margin formula
The contribution margin per unit is calculated as:
$$\text{Contribution Margin per Unit} = P  V$$
Subtract the variable cost per unit from the selling price per unit.
The contribution margin per unit is calculated by subtracting the variable cost per unit from the selling price per unit.
More Information
Knowing the contribution margin per unit helps businesses in decisionmaking processes such as pricing and determining the breakeven point.
Tips
A common mistake is to confuse variable costs with fixed costs. Ensure that only the variable costs that change with the level of production are subtracted from the selling price.
