What is variable cost?

Variable cost refers to those production expenses that change in direct proportion to the level of output or production. These costs vary with the quantity of goods produced or services rendered. Examples of variable costs include raw materials, direct labor, and sales commissions. Unlike fixed costs, which remain constant regardless of production levels, variable costs increase as production rises and decrease when production falls.

In economic terms, variable costs are crucial for determining the break-even point and profitability of a business. They are calculated per unit of production and are essential for cost-volume-profit analysis. Understanding variable costs helps businesses optimize production levels and pricing strategies to maximize efficiency and profitability.
