2-65 CVP and Break-Even

Complete the following problem sets from the Introduction to Management Accounting text: CVP and Break-Even, on p. 89 EXCEL Application Exercise Goal: Create an Excel spreadsheet to perform CVP analysis and show the relationship between price, costs, and break-even points in terms of units and dollars. Use the results to answer questions about your


Scenario: Phonetronix is a small manufacturer of telephone and communications devices. Recently, company management decided to investigate the profitability of cellular phone production. They have three different proposals to evaluate. Under all the proposals, the fixed costs for the new phone would be $110,000. Under proposal A, the selling price of the new phone would be $99 and the variable cost per unit would be $55. Under proposal B, the selling price of the phone would be $129 and the variable cost would remain the same. Under proposal C, the selling price would be $99 and the variable cost would be $49.

When you have completed your spreadsheet, answer the following questions:

1. What are the break-even points in units and dollars under proposal A?

2. How did the increased selling price under proposal B impact the break-even points in units and dollars compared to the break-even points calculated under proposal A?

3. Why did the change in variable cost under proposal C not impact the break-even points in units and dollars as significantly as proposal B did?


1. Open a new Excel spreadsheet.

2. In column A, create a bold-faced heading that contains the following:

Row 1: Chapter 2 Decision Guideline

Row 2: Phonetronix

Row 3: Cost-Volume-Profit (CVP) Analysis

Row 4: Today’s Date

3. Merge and center the four heading rows across columns A through D.

4. In Row 7, create the following bold-faced, right-justified column headings: Column

B: Proposal A Column C: Proposal B Column D: Proposal C Note: Adjust cell widths when necessary as you work.

5. In Column A, create the following row headings: Row 8: Selling price Row 9: Variable cost Row 10: Contribution margin Row 11: Contribution margin ratio Skip a row Row 13: Fixed cost Skip a row Row 15: Break-even in units Skip a row Row 17: Break-even in dollars

6. Use the scenario data to fill in the selling price, variable cost, and fixed cost amounts for the three proposals.

7. Use the appropriate formulas from this chapter to calculate contribution margin, contribution margin ratio, break-even in units, and break-even in dollars.

8. Format all amounts as: Number tab: Category: Currency Decimal places: 0 Symbol: None Negative numbers: Red with parenthesis

9. Change the format of the selling price, contribution margin, fixed cost, and breakeven in dollars amounts to display a dollar symbol.

10. Change the format of both contribution margin headings to display as indented: Alignment tab: Horizontal: Left (Indent) Indent: 1

11. Change the format of the contribution margin amount cells to display a top border, using the default line style. Border tab: Icon: Top Border

12. Change the format of the contribution margin ratio amounts to display as a percentage with two decimal places. Number tab: Category: Percentage Decimal places: 2

13. Change the format of all break-even headings and amounts to display as boldfaced.

14. Activate the ability to use heading names in formulas under Tools ? Options: Calculation tab: Check the box: Accept labels in formulas

15. Replace the cell-based formulas with “word-based” equivalents for each formula used in Proposal A. Example: Contribution margin for proposal B would be: = (‘Selling price’ ‘Proposal B’) – (‘Variable cost’ ‘Proposal B’) Read more: CVP and Break-Even Goal: Create an Excel spread…
