Study Notes

  • Costs stay the same in the short run regardless of output levels which are referred to as fixed costs.
  • Rent, insurance, heating, depreciation, business rates and capital costs are examples of fixed costs.
  • Fixed costs do not change with output in the short run but may increase due to inflation, for example.
  • A firm producing dolls has fixed costs of £400,000 regardless of how much is produced.

Variable Costs

  • Variable costs increase directly as output rises.
  • If a firm doesn't produce anything, its variable costs will be zero.
  • Variable costs include raw materials, fuel, packaging, and wages.
  • A doll manufacturer has variable costs of £2 per doll.
  • Producing 100,000 dolls will cost £200,000 (£2 x 100,000), while 600,000 dolls will cost £1,200,000 (£2 x 600,000).
  • Variable costs increase linearly with output.

Total Cost

  • Combining fixed and variable costs determines a business's total cost.
  • Total cost of production is what it costs to produce a certain level of output.
  • As output increases, so does total cost.
  • Total Cost (TC) = Fixed Cost (FC) + Variable Cost (VC)
  • A business has fixed costs of £400,000 and variable costs of £2 per doll.
  • With zero output, total costs are £400,000.
  • When output is 300,000 dolls, total costs become £1,000,000.
  • When output is 600,000, total costs are £1,600,000.
  • As output increases, fixed costs become a smaller proportion of total costs.

Average Cost

  • Average cost, also known as unit cost, is the cost per unit of production.
  • Average Cost = Total Cost / Output

Profit and Loss

  • Businesses calculate costs and revenue to determine profit or loss.
  • Profit is the difference between total revenue and total costs.
  • Profit = Total Revenue - Total Costs
