Variable Costs are defined as

• A. Independent from the volume of work.
• B. Fixed in relation to output.
• C. Costs that never change with activity.
• D. Dependent on the volume of work.

Answer: (D)

Variable costs are costs that change in total as the level of activity or volume changes. As production or sales volume increases, total variable costs rise; when volume decreases, they fall. The amount per unit typically stays constant, so total variable cost is proportional to volume. This is why direct materials and piece-rate wages increase with more output. Fixed costs, in contrast, stay the same in total regardless of output. So describing variable costs as dependent on the volume of work correctly captures how they behave.
