Answer:
Lock division's controllable margin is $208,500
Step-by-step explanation:
Controllable margin is calculated deducting from the contribution margin the controllable fixed costs.
This would be:
Revenues: $990,000
Contribution margin ratio 65%
Contribution margin: $990,000*0.65=$643,500
Controllable fixed costs: $435,000
Controllable margin: $643,500-435,000=$208,500
Controllable contribution is used to measure a divisional manager's performance as it is calculated as follows: sales revenue of a division less those costs that are controllable by the divisional manager, these are: variable costs and controllable fixed costs.
Revenues less variable costs = contribution margin
contribution margin less controllable fixed costs = controllable margin.
