A revolving budget is a financial tool designed to allocate resources for a specific period, usually a year, to support an organization's operations or a project. There are several synonyms for this concept, including rolling budget, flexible budget, dynamic budget, and adjustable budget. These alternative terms emphasize the budget's ability to adapt to changing circumstances and business needs, making it more responsive and effective. A rolling budget is likened to a rolling forecast, providing an ongoing projection of expenditures and revenue for the upcoming period. A flexible budget is one that takes into account the changes in business conditions and uses the latest available data to adjust allocation values. Dynamic budget and adjustable budget terms similarly highlight the budget's agility and versatility in the face of changing needs.
