5The Basics of Cost-Volume-Profit (CVP) Analysis Contribution Margin (CM) is the amount remaining from sales revenue after variable expenses have been deducted.
6The Basics of Cost-Volume-Profit (CVP) Analysis CM is used to cover fixed expenses.
7The Basics of Cost-Volume-Profit (CVP) Analysis After covering fixed costs, any remaining CM contributes to income.
8The Contribution Approach For each additional unit Wind sells, $200 more in contribution margin will help to cover fixed expenses and profit.
9The Contribution Approach Each month Wind must generate at least $80,000 in total CM to break even.
10The Contribution Approach If Wind sells 400 units in a month, it will be operating at the break-even point.
11The Contribution Approach If Wind sells one additional unit (401 bikes), net income will increase by $200.
12The Contribution Approach The break-even point can be defined either as:The point where total sales revenue equals total expenses (variable and fixed).The point where total contribution margin equals total fixed expenses.
13Contribution Margin Ratio The contribution margin ratio is: For Wind Bicycle Co. the ratio is:Contribution marginSalesCM Ratio =$200$500= 40%
14Contribution Margin Ratio At Wind, each $1.00 increase in sales revenue results in a total contribution margin increase of 40¢.If sales increase by $50,000, what will be the increase in total contribution margin?
15Contribution Margin Ratio A $50,000 increase in sales revenue
16Contribution Margin Ratio A $50,000 increase in sales revenue results in a $20,000 increase in CMor ($50,000 × 40% = $20,000)
17Changes in Fixed Costs and Sales Volume Wind is currently selling 500 bikes per month. The company’s sales manager believes that an increase of $10,000 in the monthly advertising budget would increase bike sales to 540 units.Should we authorize the requested increase in the advertising budget?
18Changes in Fixed Costs and Sales Volume $80,000 + $10,000 advertising = $90,000Sales increased by $20,000, but net income decreased by $2,000.
19Changes in Fixed Costs and Sales Volume The Shortcut Solution
20APPLICATIONS OF CVP Consider the following basic data: Per unit PercentSales Price $Less: Variable costContribution marginFixed costs total $35,000
21APPLICATIONSCurrent sales are $100,000. Sales manager feels $10,000 increase in sales budget will provide $30,000 increase in sales. Should the budget be changed?Incremental CM approach:$30,000 x 40% CM ratio 12,000Additional advertising expense 10,000Increase in net income 2,000YES
22APPLICATIONSManagement is considering increasing quality of speakers at an additional cost of $10 per speaker. Plan to sell 80 more units. Should management increase quality?Expected total CM= (480 speakers x$90) $43,200Present total CM= (400 speakers x$100) ,000Increase in total contribution margin 3,200 (and net income)YES
23APPLICATIONSManagement advises that if selling price dropped $20 per speaker and advertising increased by $15,000/month, sales would increase 50%. Good idea?Expected total CM= (400x150%x$80) $48,000Present total CM (400x$100) 40,000Incremental CM ,000Additional advertising cost 15,000Reduction in net income (7,000)NO
24APPLICATIONSA plan to switch sales people from flat salary ($6,000 per month) to a sales commission of $15 per speaker could increase sales by 15%. Good idea?Expected total CM (400x115%x$85) $39,100Current total CM (400x$100) 40,000Decrease in total CM (900)Salaries avoided if commission paid 6,000Increase in net income $5,100YES
25APPLICATIONSA wholesaler is willing to buy 150 speakers if we will give him a discount off our price. The sale will not disturb regular sales and will not change fixed costs. We want to make $3,000 on this sale. What price should we quote?Variable cost per speaker $150Desired profit on order (3,000/150)Quoted price per speaker $170
26Break-Even Analysis Break-even analysis can be approached in two ways: Equation methodContribution margin method.
27At the break-even point Equation MethodProfits = Sales – (Variable expenses + Fixed expenses)ORSales = Variable expenses + Fixed expenses + ProfitsAt the break-even pointprofits equal zero.
28Here is the information from Wind Bicycle Co.: Equation MethodHere is the information from Wind Bicycle Co.:
29We calculate the break-even point as follows: Equation MethodWe calculate the break-even point as follows:Sales = Variable expenses + Fixed expenses + Profits$500Q = $300Q + $80,000 + $0Where:Q = Number of bikes sold$500 = Unit sales price$300 = Unit variable expenses$80,000 = Total fixed expenses
30We calculate the break-even point as follows: Equation MethodWe calculate the break-even point as follows:Sales = Variable expenses + Fixed expenses + Profits$500Q = $300Q + $80,000 + $0$200Q = $80,000Q = 400 bikes
31Equation Method X = 0.60X + $80,000 + $0 We can also use the following equation to compute the break-even point in sales dollars.Sales = Variable expenses + Fixed expenses + ProfitsX = 0.60X + $80, $0Where:X = Total sales dollars= Variable expenses as a percentage of sales$80,000 = Total fixed expenses
32Equation Method X = 0.60X + $80,000 + $0 0.40X = $80,000 X = $200,000 We can also use the following equation to compute the break-even point in sales dollars.Sales = Variable expenses + Fixed expenses + ProfitsX = 0.60X + $80, $00.40X = $80, X = $200,000
33Contribution Margin Method The contribution margin method is a variation of the equation method.Fixed expensesUnit contribution margin=Break-even pointin units soldFixed expensesCM ratio=Break-even point intotal sales dollars
34CVP Relationships in Graphic Form Viewing CVP relationships in a graph gives managers a perspective that can be obtained in no other way. Consider the following information for Wind Co.:
38Target Profit Analysis Suppose Wind Co. wants to know how many bikes must be sold to earn a profit of $100,000.We can use our CVP formula to determine the sales volume needed to achieve a target net profit figure.
40The Contribution Margin Approach We can determine the number of bikes that must be sold to earn a profit of $100,000 using the contribution margin approach.Fixed expenses + Target profitUnit contribution margin=Units sold to attainthe target profit$80, $100,000$200= 900 bikes
41The Margin of SafetyExcess of budgeted (or actual) sales over the break-even volume of sales. The amount by which sales can drop before losses begin to be incurred.Margin of safety = Total sales - Break-even salesLet’s calculate the margin of safety for Wind.
42The Margin of SafetyWind has a break-even point of $200,000. If actual sales are $250,000, the margin of safety is $50,000 or 100 bikes.
43The Margin of SafetyThe margin of safety can be expressed as 20 percent of sales. ($50,000 ÷ $250,000)
44Operating LeverageA measure of how sensitive net income is to percentage changes in sales.With high leverage, a small percentage increase in sales can produce a much larger percentage increase in net income.Contribution marginNet incomeDegree ofoperating leverage=
46Operating LeverageWith a measure of operating leverage of 5, if Wind increases its sales by 10%, net income would increase by 50%.Here’s the proof!
4710% increase in sales from . . . results in a 50% increase in Operating Leverage10% increase in sales from$250,000 to $275,. . . results in a 50% increase inincome from $20,000 to $30,000.
48The Concept of Sales Mix Sales mix is the relative proportions in which a company’s products are sold.Different products have different selling prices, cost structures, and contribution margins.Let’s assume Wind sells bikes and carts and see how we deal with break-even analysis.
49The Concept of Sales Mix Wind Bicycle Co. provides us with the following information:$265,000$550,000= 48% (rounded)Break-even point in sales dollars:$170,0000.48= $354,167 (rounded)
50Assumptions of CVP Analysis Selling price is constant throughout the entire relevant range.Costs are linear throughout the entire relevant range.In multi-product companies, the sales mix is constant.In manufacturing companies, inventories do not change (units produced = units sold).
