A cost to a person or business that varies over time according to a number of factors. For example, a dental office must buy dental supplies, which usually cost about the same. This is a fixed cost. On the other hand, the dental office must also pay the electric and gas and water bills, which may fluctuate considerably. This is a variable cost.

The costs of production that vary directly in proportion to the number of units produced. Variable costs often include labor expenses and raw material costs, because labor and raw material usually must be increased to increase output. Firms for which variable costs represent a high proportion of total costs are usually less likely to experience large fluctuations in earnings, because changes in sales and revenues are accompanied by nearly equal changes in costs. Compare fixed cost.
