What are the limitations of flexible budgeting?
IntermediateAnswer
Limitations include the difficulty of accurately splitting mixed costs, the assumption that variable costs are strictly linear within the relevant range, ignoring step changes and economies of scale, and reliance on a single or few activity drivers. Outside the relevant range or with complex cost behavior, flexed figures can mislead.
Real-world example Assuming linear variable cost breaks down when a bulk-buying discount kicks in at higher volumes.
