Questions this Costs, scale of production and break-even analysis deck will help you answer

Definition Flip

Define 'fixed costs' and provide an example.

Answer Flip

Fixed costs are expenses that do not change with the level of production.

Example: rent for a factory remains the same regardless of how many units are produced.
Definition Flip

What are 'variable costs'?

Answer Flip

Variable costs are expenses that change directly with the level of production. Examples are the cost of raw materials and direct labor; they increase as output increases.

Key Concept Flip

Explain how to calculate 'total costs'.

Answer Flip

Total costs are the sum of all fixed costs and variable costs. The formula is: Total Costs = Fixed Costs + Variable Costs.

Definition Flip

Describe what 'average costs' represent.

Answer Flip

Average costs are the total cost of production divided by the number of units produced. It shows the cost of producing one unit on average.

Definition Flip

What is the difference between 'revenue' and 'profit'?

Answer Flip

Revenue is the total income from sales before any costs are deducted. Profit is the remaining income after all costs (fixed and variable) have been subtracted from revenue.

Key Concept Flip

Define 'break-even point' in terms of output.

Answer Flip

The break-even point is the level of output where total revenue equals total costs. At this point, the business is making neither a profit nor a loss.

Definition Flip

Explain what a 'break-even chart' illustrates.

Answer Flip

A break-even chart is a graph showing total revenue and total costs at different output levels. It visually represents the break-even point (where total revenue equals total costs) and potential profit or loss.

Example: a chart for a bakery might show they need to sell 200 cupcakes at $3 each to cover $600 in fixed and variable costs.
Definition Flip

Define 'margin of safety' and why is it important?

Answer Flip

The margin of safety is the difference between the actual level of output and the break-even output. It shows how much sales can decrease before losses occur, indicating the business's risk level.

Example: if break-even is 500 units and current sales are 700 units, the margin of safety is 200 units; meaning sales can fall by almost 30% before a loss is made.
Definition Flip

Give an example of 'economies of scale'.

Answer Flip

Economies of scale are the cost advantages that a business can exploit by increasing their scale of production. An example is purchasing economies where buying in bulk leads to discounts.

Definition Flip

What are 'diseconomies of scale'?

Answer Flip

Diseconomies of scale are the cost disadvantages that a business experiences due to becoming too large. This could be due to communication problems or lack of motivation among workers.
