What is variable cost?

Variable cost refers to the expenses that change in direct proportion to the level of production or sales in a business. These costs vary with the quantity of output produced. 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 increases and decrease when production falls. They are crucial in determining the break-even point and profit margins of a firm. Variable costs are essential for short-term decision-making, such as pricing strategies and production planning, as they directly impact the total cost of production.
