All costs and revenues are controllable at some level of responsibility within a company. This truth underscores the adage by the CEO of any organization that “the buck stops here” Under responsibility accounting, the critical issue is whether the cost or revenue is controllable at the level of responsibility with which it is associated. A cost over which a manager has control is called controllable cost.
From this definition it follows that:
- All costs are controllable by top management because of the broad range of its authority.
- Fewer costs are controllable as one moves down to each lower level of managerial responsibility because of the manager’s decreasing authority.
