Variables
Description
What is this formula?
The Contribution Margin measures how much revenue remains after covering variable costs. This remaining amount contributes toward covering fixed costs and generating profit.
The contribution margin is one of the most important concepts in managerial accounting and cost-volume-profit analysis.
When to use it
Use this formula to evaluate product profitability, determine break-even points, support pricing decisions, and analyze the financial impact of sales volume changes.
Example
A company sells a product for $50 per unit.
Data:
Selling Price = $50/unit
Variable Cost = $30/unit
Units Sold = 5,000
Formula:
CM=(SP-VC)Q
Substitution:
CM=(50-30)×5,000
CM=100,000
Result:
Contribution Margin = $100,000
Applications
Cost-volume-profit analysis
Break-even analysis
Pricing decisions
Product profitability evaluation
Business planning
Managerial accounting
Note
This formula assumes that the variable cost per unit and selling price remain constant within the analyzed range. In practice, discounts, economies of scale, commissions, and production efficiencies may cause contribution margins to vary with sales volume.
