This video discusses the rolling budget.

The rolling budget (also known as a continuous budget or a perpetual budget) is a budget that extends forward one period each time a period is completed. For example, let’s say a company prepares a monthly budget that begins in January 2024 and ends with December 2024. If the company uses a rolling budget, then at the end of January 2024, the budget will roll forward one month; this means that the new 12-month budget would begin with February 2024 and end with January 2025. Thus, each time one month ends, you add an additional month to the budget. This way the budget is begin continuously extended as time passes.
