What is Controllable Cost?
A controllable cost is a cost that a particular manager can directly influence or change within a given period. The classification depends on who holds the authority and over what time horizon. Costs not influenced by a manager are called uncontrollable from that manager’s perspective.
How It Works
- Define the cost centre and the responsible manager.
- List all costs charged to that centre and assess which the manager can change in the short term.
- Hold the manager accountable only for the controllable portion when reviewing variances.
- Reclassify items as the manager’s authority changes (for example, a regional manager promoted to country head).
Saudi Context
Responsibility accounting is common in Saudi family groups and Tadawul-listed companies where multiple cost centres roll up to a regional head. Controllable cost reporting is also used in performance bonuses linked to the Saudi labour market, where managers are evaluated on items they can actually influence.
Example
A branch manager in Riyadh can control marketing spend and overtime but not the head-office IT charge allocated to her branch. Her variance report focuses only on the controllable portion of her SAR 800,000 monthly cost base.
