Cost-Volume-Profit-Analysis

2. Types of Costs The effect of volume of activity on costs
Variable costs
Fixed costs
Mixed costs

3. Variable Costs
Total variable costs change in direct proportion to changes in the volume of activity
Volume can be measured in many different ways:
Number of units sold
Number of units produced
Number of miles driven by a delivery vehicle
Number of phone calls placed

4. Total Variable Costs

5. Fixed Costs
Tend to remain the same in amount, regardless of variations in level of activity
Total fixed costs do not change, but the fixed cost per event depends on the number of events

6. Total Fixed Costs & Fixed Costs per Unit

7. Mixed Costs
Have both a fixed and variable component

8. Mixed Costs

9. High-Low Method
Method to separate mixed costs into variable and fixed components
Identify the highest and lowest levels of activity over a period of time
STEP 1: Calculate variable cost per unit
STEP 2: Calculate total fixed cost
STEP 3: Create and use equation to show the behavior of a mixed cost

15. S19-3: Mixed costs—high-low method
Martin owns a machine shop. In reviewing his utility bill for the last 12 months, he found that his highest bill of $2,800 occurred in August when his machines worked 1,400 machine hours. His lowest utility bill of $2,600 occurred in December when his machines worked 900 machine hours.
Calculate (a) the variable rate per machine hour and (b) Martin’s total fixed utility cost.

16. S19-3: Mixed costs—high-low method

His lowest utility bill of $2,600 occurred in December when his machines worked 900 machine hours. 2. Show the equation for determining the total utility cost for Martin’s.

17. S19-3: Mixed costs—high-low method
Martin owns a machine shop. In reviewing his utility bill for the last 12 months, he found that his highest bill of $2,800 occurred in August when his machines worked 1,400 machine hours. His lowest utility bill of $2,600 occurred in December when his machines worked 900 machine hours. 3. If Martin’s anticipates using 1,200 machine hours in January, predict his total utility bill using the equation from Requirement 2.

4. Draw a graph illustrating your total cost under this plan. Label the axes, and show your costs at 900, 1,200, and 1,400 machine hours.

19. Basic CVP Analysis
Expresses the relationships among costs, volume, and profit or loss
Assumptions:
Managers can classify each cost as either variable or fixed
Only factor that affects total costs is change in volume, which increases variable and mixed costs
Fixed costs do not change

20. Breakeven Point Sales level at which operating income is zero:
Total revenues equal total costs (expenses)
Two methods to compute breakeven point:
Income statement approach
Contribution margin approach

21. Income Statement Approach
Express income in equation form and then break it down into its components:

22. Contribution Margin Approach
Shortcut method
Called contribution margin because the excess of sales revenue over variable costs contributes to covering fixed costs

23. Contribution Margin Ratio
Ratio of contribution margin to sales revenue
Used to compute the breakeven point in terms of sales dollars
Contribution margin is equal to:
Contribution margin divided by sales revenue yields a percentage

24. S19-4: Computing breakeven point in sales units
Story Park competes with Splash World by providing a variety of rides. Story sells tickets at $50 per person as a one-day entrance fee. Variable costs are $10 per person, and fixed costs are $240,000 per month.
1. Compute the number of tickets Story must sell to break even.

25. S19-4: Computing breakeven point in sales units
Story Park competes with Splash World by providing a variety of rides. Story sells tickets at $50 per person as a one-day entrance fee. Variable costs are $10 per person, and fixed costs are $240,000 per month.
1.Perform a numerical proof to show that your answer is correct.

26. S19-5: Computing breakeven point in sales dollars
Story Park competes with Splash World by providing a variety of rides. Story sells tickets at $50 per person as a one-day entrance fee. Variable costs are $10 per person, and fixed costs are $240,000 per month.
1. Compute Story Park’s contribution margin ratio. Carry your computation to two decimal places.
$50 - $10 = $40
$40 ÷ $50 = 0.80 or 80%

27. S19-5: Computing breakeven point in sales dollars
Story Park competes with Splash World by providing a variety of rides. Story sells tickets at $50 per person as a one-day entrance fee. Variable costs are $10 per person, and fixed costs are $240,000 per month.
2. Use the contribution margin ratio CVP formula to determine the sales revenue Story Park needs to break even.

28. Using CVP to Plan Profits
Managers more interested in:
Sales level needed to earn a target profit
Profits they can expect to earn
How many products or service events must be sold to earn a specific operating profit
Use either method

29. Graphing Cost-Volume-Profit Relations
Graph provides a picture that shows how changes in the levels of sales will affect profits
Four steps:
Choose a sales volume and plot the point for total sales revenue at that volume
Draw the fixed cost line
Draw the total cost line (total costs are the sum of variable costs plus fixed costs)
Identify the breakeven point and the areas of operating income and loss

40. Multiple Product Lines
Selling prices and variable costs differ for each product
Weighted-average contribution margin computed
Sales mix provides weights to make up total product sales

41. Steps for Computing Breakeven Point with Multiple Product Lines
To compute breakeven sales in units for multiple products, complete the following three steps:
Calculate the weighted-average contribution margin per unit
Calculate the breakeven point in units for the “package” of products
Calculate the breakeven point in units for each product. Multiply the “package” breakeven point in units by each product’s proportion of the sales mix
FINALLY Prove this breakeven point by preparing a contribution margin income statement
