Which of the following is most likely to be a fixed cost?

Costs are generally categorized as either fixed or variable. Fixed costs are expenses that do not change in total, regardless of the level of production or sales volume within a relevant range. Conversely, variable costs fluctuate directly with changes in activity levels.

• Directors' remuneration (salaries) is most likely a fixed cost. These salaries are typically paid on a regular basis, irrespective of the company's production volume or sales performance. They are considered period costs.
• Power costs can have both fixed and variable components, but a significant portion often varies with production (e.g., electricity for machinery running longer for higher output).
• Raw materials are a classic example of a variable cost. The more units produced, the more raw materials are consumed, and thus the total cost increases proportionally.
• Direct labor is generally considered a variable cost because the number of labor hours (and associated wages) often increases with higher production volumes. While some labor costs might be fixed (e.g., salaried supervisors), direct labor tied to production is primarily variable.
