An appreciation of cost behavior is needed in order for management to understand and predict profitability as the costs of material, labor and other operating expenses and levels of production and sales change. It's important to review the cost behavior of fixed, variable and mixed costs before contribution margins, cost-volume-profit analysis, and break-even points.

1. In the table below, Have-A-Seat Inc. has outlined many of the costs associated with producing office chairs. With respect to the production and sale of office chairs, classify each cost as fixed, mixed, or variable.

a. Pressure-molded plastic for chair frames
b. Pension cost: $0.50 per employee hour on the job
c. Insurance premiums for inventory: $2,100 per month plus $0.01 for each dollar of inventory over $2 million
d. Property taxes: $120,000 per year for the factory building and land

2. Variable costs per unit with changes in the level of activity, while fixed costs per unit as the number of units increases and as the number of units decreases.

Contribution Margin Income Statement

A contribution margin income statement organizes costs by behavior (variable or fixed), rather than by function (operating, selling, or administrative). The contribution margin is the difference between sales and .

Byron Manufacturing has one product that sells for $24.00 per unit. The company estimates fixed costs at $6,000, direct materials at $4.00 per unit, direct labor at $5.00 per unit, and variable overhead costs at $3.00 per unit.

Fill in the contribution margin income statement when 730 units are sold:

The contribution margin ratio is .

Calculating the Break-even Point:

The break-even point in sales dollars is $ which is a break-even point in units of units.

CVP Analysis using a chart:

The cost-volume-profit chart for Byron Manufacturing is shown. Use the graph to complete the sentences given below.

Byron Manufacturing reaches its break-even level of activity when it sells units and generates in revenue, because at this level of activity the firm's revenue its total cost. In addition, you can determine from the chart that Byron Manufacturing's fixed costs are and its price per unit is and variable cost per unit is .

If fixed costs increase, what will happen to the break-even point?

If the price per unit decreases, what will happen to the break-even point?

CVP analysis is used to analyze the effects of changes in selling prices, costs and volume on profits. It is also used to determine target profit, the margin of safety, operating leverage, product mix and choosing among marketing strategies and others.

Suppose Byron management has a target operating income of $3,000. Assume the same costs as above and the sell price remains at $24 per unit. How many units does Byron need to sell to meet this goal?

units

What is Byron's margin of safety in sales and in units when Byron sells 730 units?

Margin of safety in sales $ Margin of safety in units units

What is the degree of operating leverage when 730 units are sold? If required, round your answer to two decimal places.
