1. Limitations of the Annual Budget Cycle
Traditional annual budgets are built once a year. By the sixth or seventh month, the initial assumptions often become obsolete due to sudden inflation, currency shifts, or competitor price changes. This leaves managers steering the company using outdated projections.
2. Operational Mechanics of Rolling (Continuous) Budgets
A Rolling Budget keeps a continuous, 12-month forecasting window open. When one month ends, its actual data is recorded, the remaining months are updated with fresh market info, and a new 12th month is added to the back of the projection.Â
