Variable costs per unit do not changeas activity increases.

The cost per long distance

minute talked is constant.

For example, 10cents per minute.

Variable Cost Per Unit

Variable Costs Example

Consider Grand Canyon Railway. Assume that breakfast costs Grand

Canyon Railway $3 per person. If the railroad carries 2,000

passengers, it will spend $6,000 for breakfast services.

Total fixed costs remain unchangedwhen activity changes.

telephone bill probably

does not change when

you make more local calls.

Total Fixed Cost

Mixed Costs

Contain fixed portion that is incurred even when facility is unused & variable portion that increases with usage.

Example: monthly electric utility charge Fixed service fee Variable charge per kilowatt hour used

Relevant Range...

…is a band of volume in which a specific relationship exists between cost and volume.

Outside the relevant range, the cost either increases or decreases.

A fixed cost is fixed only within a given relevant range and a given time span.

Objective 2

Use CVP analysis to compute breakeven point.

Assumptions of CVP Analysis

Expenses can be classified as either variable or fixed.

CVP relationships are linear over a wide range of production and sales.

Sales prices, unit variable cost, and total fixed expenses will not vary within the relevant range.

Assumptions of CVP Analysis

Volume is the only cost driver. The relevant range of volume is

specified. Inventory levels will be unchanged. The sales mix remains unchanged

during the period.

Contribution Margin Income Statement

Sales- Variable Costs

Contribution Margin- Fixed Costs

Operating Income

Contribution Margin Example Luis and Tom manufacture a device

that allows users to take a closer look at icebergs from a ship.

The usual price for the device is $100.

Variable costs are $70 per unit. They receive a proposal from a

company in Newfoundland to sell 20,000 units at a price of $85.

Contribution Margin Example

There is sufficient capacity to produce the order.

How do we analyze this situation? $85 – $70 = $15 contribution

margin. $15 × 20,000 units = $300,000

(total increase in contribution margin)

Contribution Margin Income Statement

Sales (20,000 x $85) $1,700,000Variable costs (20,000 x $70) (1,400,000)Contribution margin $300,000

The unique sales level at which a company earns neither a profit nor incurs a loss.

Sales – Variable Costs – Fixed Costs = 0

Computing Break-Even Point

Breakeven Point Example

Let’s look back at Luis and Tom’s manufacturing, assuming that the fixed

cost are $90,000.

Various Sales Levels Example

What operating income is expected when sales are _____ units?

Target Operating Income Example

Suppose that our business would be content with operating income of _________________.

How many units must be sold?

Objective 4

Use CVP method to perform sensitivity analysis.

Change in Sales Price Example

Suppose that the sales price per device is _____ rather than ____

What is the revised breakeven sales in units?

Change in Variable Costs Example

Suppose that variable expenses per device are ____ instead of ____

Other factors remain unchanged.

Change in Fixed Costs Example

Suppose that fixed costs increased by $30,000.

What are the new fixed costs? What is the new breakeven point?

Margin of Safety Example

Excess of expected sales over breakeven sales.

Effect of sales mix on CVP analysis.

Computing MultiproductBreak-Even Point Unit contribution margin is

replaced with contribution margin for a composite unit.

A composite unit is composed of specific numbers of each product in proportion to the product sales mix.

Sales mix is the ratio of the volumes of the various products.

The resulting break-even formulafor composite unit sales is:

A company sells windows and doors. They sell 4 windows for every door.

Step 1: Compute contribution margin per composite unit.
