Budgeting & Forecasting › Rolling Forecasts

How frequently should rolling forecasts be updated and at what level of detail?

Intermediate

Answer

Update frequency (monthly or quarterly) and detail should match decision needs and the pace of change—frequent, high-level, driver-based updates are usually more valuable than infrequent, highly detailed ones. Forecast the key drivers and material lines, not every account, to stay efficient while capturing what matters for decisions.
Real-world example The team re-forecasts quarterly at a driver level, drilling into detail only for the current quarter.
