Variable Costs Definition, Types, Examples, Formula

variable costs economics definition

While COGS can also include fixed costs, such as overhead, it is generally considered a variable cost. There is also a category of costs that falls between fixed and variable costs, known as semi-variable costs (sometimes called semi-fixed costs or mixed costs). These are costs composed of a mixture of fixed and variable components. Costs are fixed for a variable costs economics definition set level of production or consumption and become variable after this production level is exceeded.

1.4.4 Costs of production (AQA Economics)

variable costs economics definition

If no production occurs, a fixed cost is often still incurred. Total Variable Cost is the cost that is directly connected with the production of any item. It is called so as such costs change as and when there is a change in the volume or quantity of outputs to be produced. This means, if the number of products to be manufactured or produced increases, it leads to the increase in these costs and if the same decreases, the variable cost also diminishes.

Business Costs and Profits – Greggs Increases Prices of Sausage Rolls

  • Operating beyond the point where marginal cost equals marginal revenue means losing money on each additional unit, even if the overall operation remains profitable.
  • Fixed Costs (FC) The costs which don’t vary with changing output.
  • So when output increases, these costs increase, and when output decreases, variables costs decrease.
  • Diminishing marginal returns is the concept that the more of something you add, the lower the impact of each additional unit, assuming all else is fixed.

For a business which produces clothing, variable cost would include the direct material, i.e., cloth, and the direct labor. The facility and equipment are fixed costs, incurred regardless of whether even one shirt is made. Variable costs are dependent on the level of production output or sales.

The total variable cost for producing these 100 cakes is $200. If the bakery increases its production to 200 cakes, the cost of each ingredient would double, resulting in a total variable cost of $400. Developing a new production process can help cut down on variable costs, which may include adopting new or improved technological processes or machinery.

  • Fixed costs include employee salaries, office rent, electricity bills, etc.
  • In addition, raw materials, production costs, delivery costs, packaging, and labor tariffs are variable expenses.
  • For example, a utility bill might have a fixed base charge plus a variable portion that increases with usage.
  • A deep understanding of these costs helps businesses set prices that not only cover all variable and fixed expenses but also ensure a profit margin.
  • This occurs where increased output leads to higher average costs.
  • Mostly, these costs include the labor cost, cost of raw materials, packaging cost, transportation costs, utility bills, or any expense that increase when the volume of produce increases.

Reasons for the Shape of Cost Curves:

  • The production process also has other costs that are equally important as the variable cost.
  • The total cost of shipping finished products varies depending on the number of units shipped.
  • An important distinction to make is that these materials only cover those that businesses use to create the final product – not other factors of production.
  • Examples of variable costs are sales commissions, direct labor costs, cost of raw materials used in production, and utility costs.
  • For example, steel is a raw material used in the construction of buildings, and fabric is used in the production of clothing.
  • Variable costs appear on the income statement of any company under the cost of goods sold (COGS) or cost of sales and are subtracted from revenue to calculate gross profit.

However, some costs may exhibit characteristics of both fixed and variable costs and are termed “semi-variable” or “mixed” costs. For example, a utility bill might have a fixed base charge plus a variable portion Bookkeeping for Painters that increases with usage. While a component of the cost remains constant, the variable portion changes based on production activity.

variable costs economics definition

Along the manufacturing income summary process, there are specific expenses that are usually variable costs. For the examples of these variable costs below, consider the manufacturing and distribution processes for an athletic apparel producer. We define variable cost by its relationship between output and cost. So when output increases, these costs increase, and when output decreases, variables costs decrease. However, after a certain output, a firm may experience diseconomies of scale.
