Variable Cost: Definition, Formula & 4 Examples

variable cost economics definition

Variable costs are not inherently good or bad—they are a reality of providing any kind of product or service to your customers. You should strive to keep variable cost per https://anageorginamurillo.com/2024/04/30/return-on-sales-101-understanding-the-ratio-3/ unit as low as possible since this will result in more profit per unit. But if your total variable costs are rising, you are producing more units—hopefully at a net profit.

What are some examples of variable costs, and how should you consider them in your business strategy? In this guide, we’ll break down everything you need to know about variable costs. Management can also use variable cost data to calculate the contribution margin, which is the selling price per unit minus the variable cost per unit. This figure is essential for breakeven analysis, which determines how many units need to be sold to cover both fixed and variable costs.

Example 3 – Break-even Analysis

A variable cost is a cost that changes with the level of production or output. As production increases, variable costs also increase, and as production decreases, variable costs decrease. If McDonald’s produces 1 Big Mac, it may cost $5 for the ingredients. By contrast, if it makes 1,000 Big Macs, the variable cost will fall significantly as it benefits from economies of scale.

3.2 Fixed and Variable Costs (Edexcel A-Level Economics Teaching PowerPoint)

Assessing economic costs helps businesses allocate resources QuickBooks efficiently, anticipate future expenditures, and plan for sustainable growth. Another way to understand the average variable cost is via the firm’s cost function, which can be plotted as a curve. The curve is a graph showing the relationship between the quantity of production and the average variable cost in the short-term production of a good or service.

An ideal variable costs equation should neither be too high nor too low to ensure a smooth flow of operations. The bakery’s monthly rent ($1,000) and the salary for a full-time baker ($3,000) are examples of fixed costs – they do not change regardless of how much bread is produced. Costs for flour, yeast, and other ingredients are variable costs since they increase as more bread is baked. If the bakery decides to bake an additional 100 loaves of bread, the cost of extra ingredients and the additional utility costs represent the marginal cost of increasing production. Average variable cost (AVC) is a concept in economics that refers to the variable cost of producing a product or service divided by the quantity of output. Variable costs are costs that vary with the level of production, such as raw materials, labor, and energy.

  • Also, the payment made on these factors remains the same whether the output is small, large, or zero.
  • Costs of production relate to the different expenses that a firm faces in producing a good or service.
  • Understanding your variable costs is essential for small and mid-sized businesses.
  • Ideally, businesses would achieve optimal profitability by achieving a production level where Marginal Revenue exactly equals Marginal Cost.
  • Examples include raw materials, direct labor, and sales commissions.
  • For example, if the average variable cost is USD 0.50 per widget, then the company should not sell any widgets for less than USD 0.50.

Raw materials, labor wages, production supplies, and energy costs are all prime examples of variable costs. Marginal cost (MC) in economics represents the incremental change in the total cost of production that results from producing one additional unit of a good or service. This article delves into the nuances of marginal cost, exploring its characteristics, influencing factors, and variable cost economics definition application within technology-driven business models. This refers to any expenses that fluctuate relative to the number of units the company produces, such as direct materials, direct labor, commissions, or utility costs. Fixed costs refer to expenses that do not change with production output, such as rent for your offices or salaries for permanent employees.

Restaurants, on the other hand, tend to have much higher variable costs, since they depend so heavily on labor. This means that service industry businesses are more vulnerable to competition since startup costs are much lower than other types of businesses. Fixed cost refers to expenses that do not change with the level of production, such as rent and salaries, and must be paid regardless of output.

  • In the above formula, AVC refers to the average variable cost, VC refers to the total variable cost, and Q refers to the output.
  • Suppose, on a given day, the cost of all the bike components, the use of the tools and machinery, the lease on its buildings, and all the labor used to produce bicycles, totals $12,900.
  • Classical economists focused on the long-term determination of prices and distribution of income.
  • Comprehending the relevance of variable costs is paramount for any business aiming to thrive in a competitive landscape.
  • The costs increase as the volume of activities increases and decrease as the volume of activities decreases.

Even if your output changes or you don’t produce anything, your fixed costs stay the same. Thus, external factors caused a $29700 change in variable expense for other months (despite outputting the same production levels). Calculated by multiplying the variable cost per unit by the number of units produced or the level of activity. Ideally, businesses would achieve optimal profitability by achieving a production level where Marginal Revenue exactly equals Marginal Cost. Here, the “profitability” would refer to the overall dollars of profit generated, not the profit per unit produced.
