rolling budget definition
A rolling budget adds a future accounting period's budget to replace a budget for an accounting period that has past. For example, a company's 2023 annual budget will become a rolling budget if in February 2023 it adds the budget for January 2024 to replace the January 2023 budget. At that point the rolling budget will cover February 1, 2023 through January 31, 2024. After February 2023 occurs, the rolling budget will consist of the 12 monthly budgets of March 1, 2023 through February 28, 2024.
The rolling budget is also referred to as a rolling horizon budget, a continuous budget, or a perpetual budget.
