Budgeting & Forecasting › Flexible Budgets
What activity measure should be used to flex a budget?
BeginnerAnswer
Use the activity measure (cost driver) that best explains the variable cost behavior—units produced, machine hours, labour hours, or another driver. Different cost pools may need different drivers. Choosing a driver that truly drives the cost gives an accurate flexed allowance; a poor driver misstates it.
Real-world example Machine-related overheads are flexed on machine hours, while packaging cost is flexed on units.
