Fixed over a small range of activity and then jump to a new fixed level with moderately small changes in volume

Explanation:

Step costs are fixed cost in nature, but it changes in steps, it don not change on a per unit basis, but after a certain activity level, it changes and then gets fixed up till next step of change.

It changes after a set of range is completed under that.

It can also be said to have variable as well as fixed component but, it as it do not change on per unit basis, the statement is not correct, as variable cost changes with each unit, Semi variable cost is the correct word for it.
