Cost Behaviour (Fixed, variable, mixed and stepped-fixed costs)

Cost behaviour is the study of how different costs change in response to changes in the level of activity or output.

It refers to the way and manner in which different costs change as the level of production changes.

Cost behaviour shows the relationship between a cost and the level of economic activity.

There are four main cost behaviour patterns, which are fixed costs, variable costs, semi-variable costs, and step fixed costs.
