Breakeven Quantity of Sales and Net Income

Breakeven Quantity of Sales and Net Income

“Breakeven point” or “breakeven quantity of sales” refers to the number of units of a company’s product that is produced and sold, at which point the company’s net income becomes zero.

Computing Breakeven Quantity of Sales

At the point where a company’s net income is zero, its revenues equal its costs. A company’s costs are, however, made up of variable operating costs, fixed operating costs, and fixed financing costs.

With this in mind, if Revenue = Costs, then:

$$ PQ = VQ + F + C $$

Where:

P = Price per unit.

Q = Number of units produced and sold.

V = Variable cost per unit.

F = Fixed operating costs.

C = Fixed financing costs.

Therefore if QBE is the breakeven quantity of sales, then:

$$ PQ_{BE}=VQ_{BE}+F+C $$

and

$$ Q_{BE}=\cfrac{F+C}{P-V} $$

In other words, a company’s breakeven sales quantity is equal to the sum of its fixed operating and financing costs divided by its unit contribution margin or the difference between the price per unit and variable cost per unit.

Example: Breakeven Quantity of Sales

Assume that a company’s product costs are represented by the figures below.

$$ \begin{array}{l|r} \text{Price per unit sold} & {$8.00} \\ \hline \text{Variable cost per unit} & {$4.00} \\ \hline \text{Fixed cost per unit} & {$2,500.00} \\ \hline \text{Fixed financing cost} & {$1,200.00} \\ \end{array} $$

What is the company’s breakeven quantity of sales?

Solution

$$ Q_{BE}=\cfrac{F+C}{P-V} = \cfrac{$2,500+$1,200}{$8-$4}=925 \text{ units} $$

Determining Net Income at Various Sales Levels

Using the example above, we can also determine a company’s net income at various sales levels.

$$ \begin{array}{c|c} \textbf{Units sold} & \bf{\text{Sales }($)} & \bf{\text{Net income } ($)} \\ \hline {625} & {5,000} & {-780} \\ \hline {725} & {5,800} & {-520} \\ \hline {825} & {6,600} & {-260} \\ \hline {925} & {7,400} & {0} \\ \hline {1,025} & {8,200} & {260} \\ \hline {1,125} & {9,000} & {520} \\ \hline {1,225} & {9,800} & {780} \\ \end{array} $$

As can be seen from the table, at the breakeven quantity of sales, net income = 0; below the breakeven quantity of sales, net income < 0, and above the breakeven quantity of sales, net income > 0.

Question

A company has fixed operating costs of $5,000 and fixed financing costs of $10,000. The price per unit for one of its products is $12.00, and the variable cost per unit is $5.00. The company’s breakeven quantity of sales is closest to:

A. 2,143.

B. 1,500.

C. 963.

Solution

The correct answer is A.

The breakeven quantity of sales can be found using the following formula:

$$ Q_{BE}=\cfrac{F+C}{P-V} = \cfrac{$5,000+$10,000}{$12.00-$5.00}=2,143 \text{ units} $$

    Excelente para el FRM 2 Escribo esta revisión en español para los hispanohablantes, soy de Bolivia, y utilicé AnalystPrep para dudas y consultas sobre mi preparación para el FRM nivel 2 (lo tomé una sola vez y aprobé muy bien), siempre tuve un soporte claro, directo y rápido, el material sale rápido cuando hay cambios en el temario de GARP, y los ejercicios y exámenes son muy útiles para practicar.

    So helpful. I have been using the videos to prepare for the CFA Level II exam. The videos signpost the reading contents, explain the concepts and provide additional context for specific concepts. The fun light-hearted analogies are also a welcome break to some very dry content. I usually watch the videos before going into more in-depth reading and they are a good way to avoid being overwhelmed by the sheer volume of content when you look at the readings.

    A great curriculum provider. James sir explains the concept so well that rather than memorising it, you tend to intuitively understand and absorb them. Thank you ! Grateful I saw this at the right time for my CFA prep.

    Professor James' videos are excellent for understanding the underlying theories behind financial engineering / financial analysis. The AnalystPrep videos were better than any of the others that I searched through on YouTube for providing a clear explanation of some concepts, such as Portfolio theory, CAPM, and Arbitrage Pricing theory. Watching these cleared up many of the unclarities I had in my head. Highly recommended.
