A financial plan that remains fixed, irrespective of changes in activity levels or actual performance, is a core element of budgetary control. It provides a pre-determined framework against which actual results are measured. Its preparation relies on a single, specific projection of sales volume or production output. An example would be a company projecting sales of 10,000 units and developing a budget based solely on that sales figure. Expenses are calculated and revenues projected based on this static assumption.
The usefulness of a non-flexible budgetary approach resides in its simplicity and ease of preparation. It offers a clear, initial benchmark for financial performance assessment. Historically, these rigid financial plans served as the primary budgeting method, providing a starting point for more sophisticated planning techniques. The key benefit is the establishment of concrete, readily understandable financial goals. However, deviations from the planned activity level render direct comparisons less meaningful, potentially obscuring underlying operational efficiencies or inefficiencies.
