Step Costs - Managerial Accounting

The video tutorial explains step costs, which are costs that remain fixed within a certain range of activity but increase to a higher level once the upper limit of that range is exceeded. An example is given using a preschool class, where a teacher can handle up to 15 students, but a 16th student requires hiring an additional teacher, thus increasing costs. The concept is visually represented as steps on a graph, where each step represents a range of activity with a fixed cost, and the cost increases as the activity surpasses each threshold.
