Variable costs are costs that change as the quantity of the good or service that a business produces changes. [1] Variable costs are the sum of marginal costs over all units produced. They can also be considered normal costs. Fixed costs and variable costs make up the two components of total cost.
In an economic model, an exogenous variable is one whose measure is determined outside the model and is imposed on the model, and an exogenous change is a change in an exogenous variable. [1]: p. 8 [2]: p. 202 [3]: p. 8 In contrast, an endogenous variable is a variable whose measure is determined by the model. An endogenous change is a change ...
A unit elastic variable (with an absolute elasticity value equal to 1) responds proportionally to changes in other variables. In contrast, an inelastic variable (with an absolute elasticity value less than 1) changes less than proportionally in response to changes in other variables. A variable can have different values of its elasticity at ...
Along with variable costs, fixed costs make up one of the two components of total cost: total cost is equal to fixed costs plus variable costs. In accounting and economics, fixed costs, also known as indirect costs or overhead costs, are business expenses that are not dependent on the level of goods or services produced by the business. They ...
In mathematics, a function is a rule for taking an input (in the simplest case, a number or set of numbers) [5] and providing an output (which may also be a number). [5] A symbol that stands for an arbitrary input is called an independent variable, while a symbol that stands for an arbitrary output is called a dependent variable. [6]
A major advantage of the high-low method is that it is relatively simple to calculate. This enables an estimate for the fixed costs and variable costs can be found in a short time, with only basic mathematics [3] and no expensive programs to run the calculations, allowing for the firm to invest their finite resources elsewhere. This is ...
More generalized in the field of economics, cost is a metric that is totaling up as a result of a process or as a differential for the result of a decision. [1] Hence cost is the metric used in the standard modeling paradigm applied to economic processes. Costs (pl.) are often further described based on their timing or their applicability.
In economics, the marginal cost is the change in the total cost that arises when the quantity produced is increased, i.e. the cost of producing additional quantity. [1] In some contexts, it refers to an increment of one unit of output, and in others it refers to the rate of change of total cost as output is increased by an infinitesimal amount.
