      • Margin of safety $ = Actual/budgeted sales - Break-even sales
    • Expressed as percentage of sales
      • Margin of safety % = (Margin of safety $ ÷ Actual/budgeted sales) × 100
  • Break-even sales level where total revenue equals total costs
    • Uses
      • Break-even sales = ÷
    • Contribution margin ratio = (Sales - ) ÷ Sales

Impact of cost changes on leverage

  • Operating leverage proportion of fixed costs in cost structure
    • Higher fixed costs lead to higher operating leverage (manufacturing)
    • Lower fixed costs result in lower operating leverage (retail)
  • High operating leverage companies more sensitive to changes
    • Small sales change leads to larger change
    • Higher risk but potentially higher rewards with increasing sales
  • Low operating leverage companies less sensitive to sales volume changes
    • Small sales change leads to smaller change
    • Lower risk but potentially lower rewards with increasing sales
  • Variable cost changes affect profitability and contribution margin
    • Lower variable costs lead to higher contribution margins and profitability (materials)
    • Higher variable costs result in lower contribution margins and profitability (labor)

Operating leverage degree and interpretation

  • (DOL) measures operating income sensitivity to sales changes
    • Calculated as percentage change in operating income ÷ percentage change in sales
      • DOL=Percentage change in operating incomePercentage change in salesDOL = \frac{\text{Percentage change in operating income}}{\text{Percentage change in sales}}
    • Also calculated using contribution margin and operating income
      • DOL=Contribution marginOperating incomeDOL = \frac{\text{Contribution margin}}{\text{Operating income}}
  • Higher DOL indicates greater operating income sensitivity to sales changes
    • DOL of 2 means 10% sales increase results in 20% operating income increase
  • Lower DOL indicates less operating income sensitivity to sales changes
    • DOL of 1.5 means 10% sales increase results in 15% operating income increase
  • Useful for understanding potential impact of sales changes on profitability
    • Helps managers make decisions about cost structure and pricing strategies (breakeven analysis)
  • Provides insights into to changes in sales volume

Key Terms to Review (28)

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.
Break-Even Sales: Break-even sales, also known as the break-even point, refers to the level of sales revenue at which a company's total costs are exactly equal to its total revenue, resulting in neither a profit nor a loss. This concept is crucial in understanding a company's margin of safety and operating leverage.
Common fixed costs: Common fixed costs are fixed costs that support more than one business segment. These costs do not change with the level of production or sales and cannot be traced directly to any single segment.
Contribution margin income statement: A contribution margin income statement is a type of income statement where variable expenses are subtracted from sales to show the contribution margin, which then covers fixed expenses and generates net operating income. This format aids in understanding cost behavior and decision-making.
Contribution Margin Income Statement: The contribution margin income statement is a financial statement that focuses on the relationship between a company's sales revenue and its variable costs. It provides a clear picture of a company's profitability by highlighting the contribution margin, which is the amount of revenue that remains after deducting variable costs, and can be used to support decision-making related to pricing, product mix, and cost control.
Contribution margin ratio: The contribution margin ratio is the percentage of each sales dollar that remains after deducting variable costs. It helps in understanding how sales affect profitability.
Contribution Margin Ratio: The contribution margin ratio is a metric that measures the proportion of each dollar of sales revenue that contributes to covering a company's fixed costs and generating profit. It represents the percentage of sales revenue that remains after deducting the variable costs associated with producing and selling the product or service.
Cost Behavior: Cost behavior refers to the relationship between a company's costs and its level of business activity or output. It describes how different types of costs, such as variable costs and fixed costs, respond to changes in the volume of production or sales.
