Which cost category changes with production volume in the short run?

• A. Variable Costs
• B. Fixed Costs
• C. Sunk Costs
• D. Depreciation

Answer: (A)

In the short run, costs are split into what changes with how much you produce and what stays the same. Variable costs change with production volume because they depend on the amount of output—more materials, more direct labor, and more energy are needed as you crank out more units. That’s why this category is the one that varies with how much you produce. Fixed costs, like rent or salaries not tied to output, don’t change in the short run. Sunk costs are past expenditures and aren’t influenced by current production decisions. Depreciation is typically treated as fixed in the short run, since it’s allocated over time rather than tied to current production levels (unless a usage-based method is specified).
