Having a supervisor for every ten employees can be classified as a step cost. This type of cost is characterized by its behavior in relation to changes in the level of activity, typically represented by the number of employees in this scenario.

Step costs remain fixed within certain ranges of activity or production levels, but increase in a stair-step manner when a threshold is reached—such as in this case, every time the workforce increases by a specific number, a new supervisor is required. For instance, if there are 11 employees, one supervisor might suffice, but when the number of employees increases to 20, a second supervisor becomes necessary, effectively "stepping up" the total supervisory cost.

This concept differentiates step costs from fixed costs, which do not change with the level of activity (regardless of the number of employees), and variable costs, which change proportionally as the activity level changes. Mixed costs contain both fixed and variable components but would not specifically address the situation of adding supervisors at specific intervals. Understanding this helps in budgeting and cost planning, particularly in managing organizational structures.
