Study Notes
Contribution Margin and Break-Even Analysis
- Contribution margin graph: plot total expenses and total sales at a chosen sales volume, draw lines to fixed expenses and the point of origin
- Contribution margin ratio (CM ratio): calculated as contribution margin per unit divided by selling price per unit
- Variable expense ratio: calculated as variable expenses divided by sales
- Applications of contribution ratio: increase in sales volume will increase contribution margin
- Example 1: Increasing unit sales by 40 units with a $10,000 increase in advertising budget decreased net operating income by $2,000
- Example 2: Increase in unit sales from 500 to 580 with a $10 increase in variable costs per unit resulted in a $10,200 increase in net operating income
- Example 3: Sales increased by $62,000, fixed costs increased by $15,000, and net operating income increased by $2,000 after reducing selling price and increasing advertising budget
- Example 4: Switching from fixed salaries to sales commission resulted in a $12,375 increase in net operating income after increasing unit sales
- Example 5: To increase monthly profits by $3,000, RBC should quote a price of $320 per bike to sell 150 bikes to a wholesaler
- Break-even analysis: unit sales at break-even calculated using contribution margin formula and equation method
- Formula method: a shortcut version of the equation method, each unit sold contributes towards covering fixed expenses
- Dollar sales at break-even: computed using both the equation and formula methods
