  • Determine the sales mix, the relative proportion of each product sold
    • Calculate sales mix percentage for each product by dividing units sold of each product by total units sold (Product A: 60%, Product B: 40%)
  • Calculate weighted-average contribution margin per
    • Multiply each product's contribution margin per unit by its sales mix percentage
    • Sum weighted contribution margins to obtain weighted-average contribution margin per (30×6030 × 60% + 20 × 40% = $26)
    • This calculation is closely related to the , which represents the proportion of each sales dollar available to cover fixed costs and generate profit
  • Calculate weighted-average selling price per composite unit
    • Multiply each product's selling price by its sales mix percentage
    • Sum weighted selling prices to obtain weighted-average selling price per composite unit (50×6050 × 60% + 40 × 40% = $46)
  • Determine company's total fixed costs ($100,000)
  • Calculate break-even point in composite units using formula:
    • Breakeven point in composite units=Total fixed costsWeightedaverage contribution margin per composite unitBreak-even\ point\ in\ composite\ units = \frac{Total\ fixed\ costs}{Weighted-average\ contribution\ margin\ per\ composite\ unit} (100,000÷100,000 ÷ 26 = 3,846 composite units)
  • Convert break-even point in composite units to individual product units
    • Multiply break-even point in composite units by each product's sales mix percentage (Product A: 3,846 × 60% = 2,308 units, Product B: 3,846 × 40% = 1,538 units)

Effects of sales mix on profitability

  • Changes in sales mix impact weighted-average contribution margin per composite unit
    • New sales mix favoring products with higher contribution margins increases weighted-average contribution margin per composite unit (shifting from 60/40 to 70/30 mix)
    • New sales mix favoring products with lower contribution margins decreases weighted-average contribution margin per composite unit (shifting from 60/40 to 50/50 mix)
  • Changes in weighted-average contribution margin per composite unit affect break-even point
    • Increase in weighted-average contribution margin per composite unit lowers break-even point (higher margins require fewer units to break even)
    • Decrease in weighted-average contribution margin per composite unit raises break-even point (lower margins require more units to break even)
  • Profitability affected by changes in sales mix
    • Shifting sales towards products with higher contribution margins increases overall profitability (focusing on high-margin products boosts profits)
    • Shifting sales towards products with lower contribution margins decreases overall profitability (selling more low-margin products reduces profits)

CVP analysis for pricing decisions

  • Identify limiting resource (constraint) restricting company's production capacity (machine hours, labor hours)
  • Calculate contribution margin per unit of limiting resource for each product
    • Divide each product's contribution margin per unit by amount of limiting resource required to produce one unit (Product A: 30÷2machinehours=30 ÷ 2 machine hours = 15/hour, Product B: 20÷1machinehour=20 ÷ 1 machine hour = 20/hour)
  • Rank products based on contribution margin per unit of limiting resource
    • Products with higher contribution margins per unit of limiting resource prioritized (Product B ranked higher than Product A)
  • Allocate limiting resource to products based on ranking
    • Produce and sell product with highest contribution margin per unit of limiting resource until resource fully utilized or market demand met (allocate machine hours to Product B first)
    • Continue allocating limiting resource to next highest-ranked product until resource exhausted or all demand satisfied (allocate remaining machine hours to Product A)
  • Consider adjusting prices to optimize profitability
    • Increasing prices on products with high demand and low price sensitivity improves contribution margins (raising prices on popular, essential products)
    • Decreasing prices on products with low demand and high price sensitivity stimulates sales and increases overall contribution (offering discounts on slow-moving, discretionary products)

Additional CVP Analysis Concepts

  • measures the extent to which a company uses fixed costs in its operations, affecting the sensitivity of profits to changes in sales volume
  • represents the difference between actual or projected sales and break-even sales, indicating how much sales can decline before reaching the break-even point
  • extends break-even analysis to determine the sales volume required to achieve a specific profit goal, incorporating both fixed costs and desired profit into the calculation
  • , the complement of the , represents the proportion of each sales dollar that goes towards covering variable costs

Key Terms to Review (23)

Break-Even Analysis: Break-even analysis is a fundamental concept in managerial accounting that determines the point at which a company's total revenue equals its total costs, meaning the company has neither a profit nor a loss. It is a valuable tool for understanding the relationship between a company's fixed costs, variable costs, and sales volume, and for making informed decisions about pricing, production, and profitability.
Break-even point: The break-even point is the level of sales at which total revenues equal total costs, resulting in zero profit. It can be calculated in both units and dollars to determine the required sales volume or revenue needed to cover all fixed and variable costs.
Break-Even Point: The break-even point is the level of sales or production at which a company's total revenue exactly equals its total costs, resulting in neither a profit nor a loss. It is the point where a company's fixed and variable costs are covered by its sales revenue.
