What are variable costs?

What are variable costs?

• A. Costs that vary with output or number of clients served
• B. Fixed costs that do not change with output
• C. Costs that only occur during peak season
• D. Costs unrelated to operations

Answer: (A)

Variable costs are the expenses that change in total as the level of activity changes, such as materials used per unit produced or the labor tied directly to production volume. If you increase output or serve more clients, these costs rise; if activity drops, they fall. The cost per unit often stays roughly constant, so total variable costs move up or down with production. This distinguishes them from fixed costs, which stay the same regardless of activity (like rent or base salaries), and from costs that occur only during certain seasons or that aren’t related to ongoing operations.
