The Break-Even PointThe break-even point is the point in the volume of
activity where the organization’s revenues andexpenses are equal.

Contribution-Margin Approach
Consider the following information developedby the accountant at Curl, Inc.:
Total Per Unit PercentSales (500 surf boards) 250,000$ 500$ 100%Less: variable expenses 150,000 300 60%Contribution margin 100,000$ 200$ 40%Less: fixed expenses 80,000Net income 20,000$

Contribution-Margin Approach
For each additional surf board sold, Curlgenerates $200 in contribution margin.

Contribution-Margin Approach
Here is the proof!
Total Per Unit PercentSales (400 surf boards) 200,000$ 500$ 100%Less: variable expenses 120,000 300 60%Contribution margin 80,000$ 200$ 40%Less: fixed expenses 80,000Net income -$

400 × $500 = $200,000 400 × $300 = $120,000

Contribution Margin Ratio
Calculate the break-even point in sales dollars ratherthan units by using the contribution margin ratio.

Graphing Cost-Volume-ProfitRelationships
Viewing CVP relationships in a graph givesmanagers a perspective that can be obtained in no
other way.Consider the following information for Curl, Inc.:

Target Net Profit
We can determine the number ofsurfboards that Curl must sell to earn aprofit of $100,000 using the contribution
margin approach.
Fixed expenses + Target profitUnit contribution margin = Units sold to earn
the target profit
$80,000 + $100,000$200 = 900 surf boards

Equation ApproachSales revenue –Variable expenses –Fixed expenses = Profit
($500 × X) ($300 × X)– – $80,000 = $100,000
($200X) = $180,000
X = 900 surf boards

Applying CVP Analysis
Safety MarginThe difference between budgeted sales
revenue and break-even sales revenue.The amount by which sales can drop
before losses begin to be incurred.

Safety Margin
Curl, Inc. has a break-even point of $200,000. Ifactual sales are $250,000, the safety margin is
$50,000 or 100 surf boards.Break-even

Changes in Fixed Costs
Curl is currently selling 500 surf boards permonth.
The owner believes that an increase of $10,000in the monthly advertising budget, wouldincrease bike sales to 540 units.
Should we authorize the requested increase inthe advertising budget?

Changes in Fixed Costs
Sales will increase by$20,000, but net income
decreased by $2,000.

Changes in UnitContribution Margin
Because of increases in cost of raw materials,Curl’s variable cost per unit has increasedfrom $300 to $310 per surf board. With no
change in selling price per unit, what will bethe new break-even point?
($500 × X) ($310 × X)– – $80,000 = $0
X = 422 units (rounded)

Predicting Profit GivenExpected Volume
In the coming year, Curl’s owner expects to sell525 surfboards. The unit contribution marginis expected to be $190, and fixed costs are
expected to increase to $90,000.
($190 × 525) – $90,000 = X
X = $9,750 profit
X = $99,750 –$90,000
Total contribution - Fixed cost = Profit

CVP Analysis with MultipleProducts
For a company with more than one product,sales mix is the relative combination in which
a company’s products are sold.Different products have different selling prices,
cost structures, and contribution margins.
Let’s assume Curl sells surf boards and sailboards and see how we deal with break-
even analysis.

Assumptions UnderlyingCVP Analysis
Selling price is constant throughoutthe entire relevant range.
Costs are linear over the relevantrange.
In multi-product companies, thesales mix is constant.
In manufacturing firms, inventoriesdo not change (units produced =units sold).

Cost Structure and OperatingLeverage
The cost structure of an organization is therelative proportion of its fixed and variablecosts.
Operating leverage is . . . the extent to which an organization uses
fixed costs in its cost structure. greatest in companies that have a high
proportion of fixed costs in relation to variablecosts.
