Chapter 19: Business Costs, Scale of Production, and Break-Even Analysis

Vocabulary flashcards covering business costs, economies and diseconomies of scale, and break-even analysis from Chapter 19.

Cost

The amount spent to produce goods and services, requiring raw materials, labour, and other resources.

Fixed Cost

Costs that do not change with the output level and must be paid regardless of whether the business is producing output or making a profit (e.g., rent, insurance, management salaries, electricity, depreciation, and marketing expenses).

Variable Cost

Costs that change in direct proportion to output (e.g., raw materials, transportation cost, and packaging materials).

Total Cost

The sum of all variable costs and fixed costs of producing total output.

Takeaway Pizza Cost Calculation

Given output of $800\text{ units}$, fixed cost of $600$, variable cost per unit of $1$, and selling price of $2.5$: Total Variable Cost ($\text{TVC}$) is $800 \times 1 = 800$, Total Cost ($\text{TC}$) is $600 + 800 = 1400$, Revenue is $800 \times 2.5 = 2000$, and Profit is $2000 - 1400 = 600$.

Economies of Scale

The reduction in average cost as a result of an increase in the scale of operations.

Purchasing Economies

An economy of scale where large businesses buy raw materials in bulk quantities and receive discounts from suppliers, reducing the unit cost of raw materials.

Managerial Economies

An economy of scale where large businesses employ specialist managers for functional areas (marketing, finance, operations, HR), improving decision quality, operational efficiency, and reducing average costs.

Marketing Economies

An economy of scale where total marketing costs do not rise even if production and sales double, resulting in lower average marketing costs as output increases.

Financial Economies

An economy of scale where larger businesses borrow money more easily and at lower expense because banks view them as having a low risk of non-payment.

Technical Economies

An economy of scale where large businesses afford advanced technologies (such as CAM, CAD, and CIM) and flow production to manufacture high volumes at a lower average cost.

Diseconomies of Scale

Factors that cause average costs to rise as a business expands beyond a certain size.

Poor Communication (Diseconomy)

A diseconomy of scale occurring when business growth prevents direct communication between managers and staff, adding layers of hierarchy that distort messages, slow decisions, and increase mistakes.

Lack of Commitment from Employees (Diseconomy)

A diseconomy of scale where employees in large firms feel unvalued and demotivated, resulting in higher labour turnover, reduced work quality, and declining productivity.

Weak Coordination (Diseconomy)

A diseconomy of scale where having multiple departments and internationally dispersed production units impairs communication and coordination, leading to wasted resources and higher costs.

Lack of Control (Diseconomy)

A diseconomy of scale where management lacks a close working relationship with all employees, resulting in lower worker motivation, reduced productivity, and increased unit costs.

Break-Even

The specific level of output where total revenue equals total cost, meaning the business makes neither a profit nor a loss.

Break-Even Analysis

A business technique that illustrates the relationship between revenue, cost, and the volume of output or sales.

Simple Break-Even Chart

A graphical tool used to find the level of output that must be produced and sold to earn revenue that exactly matches total production costs.

Requirements for a Break-Even Chart

Revenue at $0$ output and capacity, total cost at $0$ output and capacity, and fixed cost at $0$ output and capacity.

Break-Even Point Formula

$\text{Break-even point} = \frac{\text{Fixed cost}}{\text{Price} - \text{Variable cost}}$ or $\frac{\text{Fixed cost}}{\text{Contribution}}$

Contribution

The selling price of a product minus its variable cost ($\text{Contribution} = \text{Price} - \text{Variable cost}$).

Margin of Safety

The difference between the current level of output and the break-even output ($\text{Margin of safety} = \text{Total output} - \text{Break-even output}$).

Uses of Break-Even Analysis

Calculates required sales to reach profitability, evaluates profit changes from price or cost adjustments, assesses how far sales can drop before losing money, and supports loan applications to bank managers.

Benefits of a Break-Even Chart

Easy to construct and interpret, calculates expected profit or loss at any output level, shows the margin of safety, and allows decision impacts to be visualized by redrawing the graph.

Disadvantages of a Break-Even Chart

Assumes all produced goods are sold, ignores changes in fixed costs caused by scale changes, overlooks broader production aspects, and fails to account for wage shifts or bulk discounts over time.
