Forecast

The forecast is an estimate of what will actually be achieved. Its characteristics of the hotel forecast are:

• The hotel forecast is typically limited to rooms’ revenue, although some properties will also forecast ancillary revenue but generally, this is done in a separate forecast document or page.
• The forecast is updated at regular intervals depending on the type of property, this could be weekly, monthly or quarterly.
• The forecast may be used for short-term operational considerations, such as adjustments to staffing, tactical pricing levels, marketing investment, and distribution.
• Changes in the forecast do not impact performance-based compensation paid to employees.

The key difference between a budget and a forecast is that the budget is a plan for where a business wants to go, while a forecast is an indication of where it is actually going.
