IGCSE Business Studies - Cost Scale Production and Break-even Analysis

Overview

• Presenter: Yi from You Miss Easy
• Lesson: 4.2 Cost Scale Production and Break-even Analysis
• Objectives:
  • Describe and classify costs (4.2.1)
  • Understand economies and diseconomies of scale (4.2.2)
  • Perform break-even analysis (4.2.3)

4.2.1 Identify and Classify Costs

Importance of Cost Consideration

• Essential for planning, evaluating profitability, and pricing decisions.

Types of Costs

Fixed Costs

• Do not vary with the level of production in the short term.
• Examples: Management salaries, rent.
• Also known as overhead costs.

Variable Costs

• Vary directly with the number of items produced or sold.
• Examples: Material costs, piece-rate labor costs.

Total Costs and Average Costs

• Total Cost: Fixed + Variable costs.
• Average Cost per Unit: Total cost of production / Total output.
• Example Calculation:
  • Total production cost: $150,000.
  • Total output: 30,000 pairs of shoes.
  • Average cost per unit: $5.

Uses of Cost Data

1. Setting Prices:
   • Ensure selling price covers average cost.
2. Deciding Production Continuation:
   • Example: Stop production if costs exceed revenue.
3. Selecting Location:
   • Evaluate total costs of different locations for optimal decision-making.

4.2.2 Economies and Diseconomies of Scale

Economies of Scale

• Factors that reduce average costs as business size increases.
• Examples:
  • Purchasing Economies: Discounts on bulk purchases.
  • Marketing Economies: Reduced transport costs with larger vehicles.
  • Financial Economies: Lower interest rates for large businesses.
  • Managerial Economies: Afford specialized managers, increasing efficiency.
  • Technical Economies: Use of advanced machinery and flow production.

Diseconomies of Scale

• Factors that increase average costs as business size grows too large.
• Examples:
  • Poor Communication: Challenges in large organizations lead to errors.
  • Lack of Employee Commitment: Feeling of being unimportant in large firms.
  • Weak Coordination: Slow decision-making and coordination in large firms.
• Some large businesses mitigate these by breaking up into smaller units.

4.2.3 Break-even Analysis

Concept of Break-even

• Indicates minimum output needed to cover total costs.
• Important for new businesses to avoid losses.

Break-even Chart

• Requires fixed costs, variable costs, revenue data.
• Example: Sport shoe business with fixed costs of $5,000, variable cost $3 per pair, selling price $8 per pair, max production 2,000 pairs.
  • Axes: X-axis (units of production), Y-axis (costs and revenue).
  • Lines: Variable cost, fixed cost, total cost, sales revenue.
  • Break-even Point: Intersection of total cost and sales revenue lines; indicates no profit, no loss (1,000 units in example).

Break-even Formula

• Break-even units = Fixed Cost / (Selling Price per Unit - Variable Cost per Unit).
• Example Calculation: Using provided costs and revenues to construct break-even chart and determine profit/loss areas.

Benefits and Limitations

Advantages

• Visual representation of profit/loss at different production levels.
• Helps in decision making (e.g., pricing, stopping production).

Disadvantages

• Assumes all produced goods are sold.
• Fixed costs may not remain constant with production scale changes.
• Does not account for all aspects of business operations.

Definitions

• Fixed Costs: Do not vary with production level.
• Variable Costs: Vary with production level.
• Total Costs: Combination of fixed and variable costs.
• Average Cost per Unit: Total cost divided by total output.
• Economies of Scale: Reduction in average costs with increased output.
• Diseconomies of Scale: Increase in average costs with excessive growth.
• Break-even Level of Output: Output level where total revenue equals total cost.
• Break-even Chart: Visual representation of costs, revenue, and break-even point.
• Revenue: Income from sales.
• Margin of Safety: Sales amount exceeding break-even point.
• Contribution: Selling price minus variable cost per unit.
