Principal budget factor

The principal budget factor is the main constraint limiting the organisation’s planned activity during the budget period. It may be sales demand, skilled labour, machine capacity, material availability or finance. Identify it early so other budgets can be coordinated around the feasible activity level. The principal factor can change between periods and should not be assumed to be sales in every business. It is related to, but not identical with, every operational bottleneck.

Worked example

Demand is 20,000 units but available skilled labour permits only 15,000. The labour constraint determines the initial production plan unless extra capacity is obtainable.

Common mistake

Do not build purchasing and staffing budgets around unconstrained sales aspirations when the resource plan cannot deliver them.
