An expense that fluctuates in direct proportion to changes in total volume is ___________?
Show answer Hide answer
Answer: B. variable cost
Explanation
A variable cost changes in direct proportion to changes in total activity volume. If production output doubles, the total variable cost also doubles, while the per-unit cost remains constant. This direct proportionality defines variable cost behavior. Variable costs include expenses like direct materials and piece-rate labor that are directly tied to production volume. Within a relevant range of activity, their total amount moves up or down alongside output levels. They contrast sharply with fixed costs that remain static in total.
Understanding variable costs is critical for cost-volume-profit analysis and setting short-term break-even points. Management relies on accurate variable cost identification to predict how expenses will react to scale expansions. Fixed costs remain constant in total regardless of fluctuations in production volume. Total cost combines both fixed and variable elements, and infeasible cost is a distractor term.
