About Box Office Projection Calculator

Total gross is projected as the opening weekend times a multiplier, which typically runs from about 2.0 for front-loaded blockbusters to 4.0 or more for word-of-mouth hits. The per-screen average is the cleaner measure of demand, since a large opening spread across four thousand screens signals less strength than the same figure on fifteen hundred.
