The film calculation (also called film budget) together with quality requirements and deadlines form the basis for every film production.
The level of detail of a calculation usually depends on the complexity of the respective project.
A calculation for film and video is usually created several times and in different forms. As an indicative calculation, with a lump sum as a fixed price, but also as a final calculation or to determine the location during an ongoing video production or film production.
The quality of a budget is risk-relevant. The greater the know-how of the creator and the more precisely a film calculation is prepared, the less unpleasant surprises threaten.
Professional film productions usually work with a reserve included in the film budget. In the project business, reserves for unforeseen events should not be the exception but the rule.
