Which statement best describes variable costs?

Which statement best describes variable costs?

• A. Costs that stay constant regardless of production
• B. Costs that change depending on how much you produce
• C. Costs that are fixed by contract
• D. Costs that do not exist in service businesses

Answer: (B)

Variable costs are costs that change in response to the level of production or activity. When you produce more, you buy more materials, pay more direct labor, and use more utilities, so these costs rise. When output drops, these costs fall accordingly. This is different from fixed costs, which stay the same regardless of how much you produce, like rent or salaries. The idea that costs are fixed by contract isn’t what defines variable costs, and service businesses do incur variable costs too (such as hourly wages or consumables used in delivering a service). So costs that change with production best describe variable costs.
