Which of the following would NOT be a typical component of a break-even analysis?

• A. Break-even output is a key component of break-even analysis.
• B. Fixed costs are included in break-even analysis.
• C. Variable costs per unit are included in break-even analysis.
• D. Market share as a percentage of total market is not a typical component.

Answer: (D)

Break-even analysis focuses on the costs and revenues needed to cover total costs, so it uses fixed costs, variable costs per unit, and the selling price to determine how many units must be sold to break even. Fixed costs stay the same regardless of output, while variable costs rise with each unit produced; the contribution margin per unit (price minus variable cost per unit) drives the calculation of break-even output. Market share, being a measure of a firm’s portion of the total market, doesn’t enter into this costing and revenue math, so it wouldn’t be a typical component.
