Cost-Volume-Profit Analysis and Planning

Profitability Analysis Involves examining the relationships

among revenues, costs, and profits Widely used in the economic

evaluation of existing or proposed products or services

Performed before decisions are finalized • Selling prices

• Behavior of activity cost drivers

What you need to understand to

perform profitability analysis

CVP Assumptions1. All costs are classified as fixed or

variable.2. The total cost function is linear

within the relevant range.3. The total revenue function is linear

within the relevant range.4. The analysis is for a single product,

or the sales mix of multiple products is constant.

5. There is only one activity cost driver: unit or dollar sales volume.

Example Using the Profit Equation

Chillin’ Time produces and sells one product, ice cream bars, for $1.50 each. To ensure top quality, no inventories are maintained.

Variable Costs Per Ice Cream Bar Fixed Costs Per Month Manufacturing costs: Manufacturing overhead $1,200 Direct materials $0.43 Selling and administrative 580 Direct labor 0.32 Total $1,780 Manufacturing overhead 0.20 $0.95 Selling and administrative 0.15 Total $1.10

RV = (FC+DP)/(SP-VCU)RV=($1,780+$1,000)/($1.50-$1.10)=6,950

Estimated costs are:

Required volume to earn $1,000:

Functional Income Statement Example

Chillin’ TimeFunctional Income Statement

For a Monthly Volume of 6,950 Ice Cream Bars

Sales (6,950 x $1.50) $10,425. Less cost of goods sold:

Gross margin 2,623. Less other expenses:

Variable selling and administrative (6,950 x $0.15) 1,043 Fixed selling and administrative 580 (1,623)

Profit $ 1,000.

Contribution Income Statement

Analysis Using Contribution Margin Ratio Unit contribution margin

Indicates how sensitive an income model is to a change in unit sales

Contribution margin ratio The portion of every sales dollar

contributed toward covering fixed costs and earning a profit

Contribution Margin Example

$1.50 – $1.10 = $0.40

Total Per Unit Sales (6,950 units) $ 10,425. $ 1.50 Variable costs (7,645) -1.10Contribution margin 2,780. $ 0.40 Fixed costs (1,780)Profit $ 1,000.

[$1.50 – $1.10] ÷ $1.50 = 0.2667

Contribution margin per unit:

Contribution margin ratio:

Chillin’ Time’s contribution income appears below:

Sensitivity Analysis

100 × $0.40 = $40

If sales increase by 100 ice cream bars per month, by how much will net income increase?

Total Per Unit Ratio to Sales Sales (6,950 units) $10,425. $ 1.50 1.000Variable costs (7,645) (1.10) (0.733)Contribution margin 2,780. $ 0.40 0.267 Fixed costs (1,780)Profit $ 1,000.

$1,050 × 0.2667= $280

If sales increase by $1,050 per month, by how much will net income increase?

EXAMPLE:

Break-Even Point Example

Chillin’ Time’s Break-Even Unit =

Sales Volume

= Fixed costsContribution margin per unit

$1,780$1.50 – $1.10 = 4,450 units

When Chillin’ Time sells 4,450 ice cream bars per month, it will break even.

Chillin’ Time sells ice cream bars with a $1.10 unit variable cost for $1.50 each.

How many bars must it sell to break even?

Impact of Income TaxesDetermining the unit sales volume required to earn a desired after-tax profit:

Solve for the required unit sales volume.

Step 1: Determine the required before-tax profit.

Substitute the required before-tax profit into the profit formula.

Step 2:

Step 3:

Before-tax profit = After-tax profit(1 – tax rate)

Impact of Income Taxes Example

Before-tax profit = After-tax profit(1 – tax rate)

Chillin’ Time sells ice cream bars with a $1.10 unit variable cost for $1.50 each. It is subject to a 30 percent income tax rate. How many ice cream bars must Chillin’ Time sell to earn a desired monthly after-tax profit of $840?

$840(1 – 0.30) = = $1,200

Target unit sales volume = $1,780 + $1,200

$1.50 – $1.10

= 7,450 ice cream bars

Multiple Product Break-Even Point

Applicable when unit information is not available or when a company sells more

than one product.

= Fixed costsContribution margin ratio

= Fixed costs + Desired profit

Contribution margin ratio

Dollar break-even point

Target dollar sales volume

Sales Mix Analysis Sales mix

The relative portion of unit or dollar sales that are derived from each product

When sales mix is constant, the basic cost-volume-profit model can be used effectively

When sales mix is not constant, must determine average unit contribution margin or average contribution margin ratio for each alternative mix

Unit Sales AnalysisChillin’ Time now has two products--ice cream bars and popsicles, with the following information: Ice Cream Bars Popsicles Total Unit sales 5,000 5,000 10,000 Selling price per unit $1.50 $0.50 Variable cost per unit $1.10 $0.25Fixed costs per month $ 1,780

Sales revenue $7,500 $2,500 $10,000 Variable costs 5,500 1,250 6,750 Contribution margin $ 2,000 $1,250 $ 3,250 Contribution margin ratio 0.267 0.500 0.325

Current sales mix based on units: 5,000 to 5,000 or 1 to 1. Chillin’ Time sells 1 ice cream bar for every popsicle.

Unit Multiproduct Break-Even Example

Average contribution margin per unit = [($0.40 × 1) + ($0.25 × 1)] ÷ 2 units= $0.325

Unit break-even point =Fixed costs

Contribution margin per unit

Ice cream bars: 5,477 × 1/2 = 2,739* and

Popsicles: 5,477 × 1/2 = 2,739*

= 5,476.9 ≈ 5,477 units$1,780$0.325=

Unit Multiproduct Break-Even Example

Average contribution margin per unit = [($0.40 × 4) + ($0.25 × 1)] ÷ 5 units = $0.37

Unit break-even point with new sales mix =Fixed costs

Contribution margin per unit

Ice cream bars: 4,811 × 4/5 = 3,849 and

Popsicles: 4,811 × 1/5 = 962= 4,811 units$1,780

$0.37=

If the sales mix changes to 4:1, how much will the unit break-even sales volume be?

Comparing Break-Even Example

Sales mix 1 to 1

Ice cream bars: 5,477 × 1/2 = 2,739* and

Popsicles: 5,477 × 1/2 = 2739*

Ice cream bars: 4,811 × 4/5 = 3,849 and

Popsicles: 4,811 × 1/5 = 962

The change in sales mix causes the total number of units needed to break even to change because of the

different contribution margins for the two products.

Break-even units

Sales mix 4 to 1

Dollar Multiproduct Break-Even Example

Current sales mix in dollars is 7,500 to 2,500 or 75% to 25%. How much is the break-even sales volume in dollars?

Measuring Expected Change in Profit

Taco King and Mexi Land are competitors and reported the same sales revenue and before-tax profit during May: Taco King Mexi Land

Sales $40,000 $40,000. Variable costs (22,000) (8,000) Contribution margin 18,000 32,000. Fixed costs (8,000) (22,000) Before-tax profit $10,000. $10,000.

If sales drop by 20% for both, which company suffers more?

Degree of operating leverage

Taco King Mexi Land $18,000$10,000

= 1.8 $32,000$10,000 = 3.2

Decrease in profit

1.8 × 20% = 36%Decline in Profit

3.2 × 20% = 64%Decline in Profit

Mexi Land’s higher operating leverage results in a larger profit decline.
