Box office numbers explained: domestic, worldwide, opening weekend and studio share

Box office numbers make headlines every Sunday, but “domestic”, “worldwide”, “opening weekend” and “gross” each mean something specific. And none of them is profit. This guide explains how box office numbers are collected and reported, the difference between estimates and actuals, how much of the money studios actually keep, and how to read a record claim. Current as of September 2026.

The short answer

• Gross: money from cinema ticket sales only. It excludes streaming, home entertainment and TV rights.
• Domestic: in Hollywood reporting, the United States and Canada. International is everywhere else, and worldwide is the two added together.
• Opening weekend: Friday to Sunday of release weekend, with Thursday-night previews usually included in Friday’s total.
• Estimates vs actuals: studios report weekend estimates on Sunday, and the actuals follow on Monday.
• Studio share: on average the distributor receives “a little more than half” of the gross, according to Box Office Mojo. The cinemas keep the rest.

Where box office numbers come from

Cinemas record ticket sales. Distributors (the studios) report their films’ grosses, and measurement firms, chiefly Comscore, compile the data. Public databases such as Box Office Mojo, owned by IMDb, and The Numbers publish the results. Trade outlets such as Variety, Deadline and The Hollywood Reporter report them with analysis.

The same system works in Nigeria, where cinema data is compiled through Comscore and published by the Cinema Exhibitors Association of Nigeria and distributors such as FilmOne. We explain the local picture in our guide to the highest-grossing Nollywood films.

Box office numbers: the key terms

Box Office Mojo stresses the point about theaters: one location may show a film on several screens, and reports often confuse the two. Our Primetime box office story showed a small version of this, with The Numbers listing 2,874 cinemas and Variety reporting 2,863.

The weekend timetable: estimates, then actuals

According to Box Office Mojo’s tracking guide, studio estimates arrive on Sunday morning, usually between 9am and 10am Pacific Time, or roughly 5pm to 7pm in Nigeria depending on US daylight saving. An estimate combines Friday and Saturday takings with a projection for Sunday. Actual weekend figures come on Monday, generally after 1pm Pacific Time, and late updates are possible.

So Sunday headlines are forecasts, and the ranking can change on Monday when a close race is settled. Daily figures are generally reported by noon Pacific Time the next day.

Thursday previews count towards Friday. Variety explained in 2018 that studios had moved previews from midnight to Thursday evening, typically 7pm or 8pm, and that “Thursday preview grosses are folded into Friday totals”. Previews are also an early signal: The Meg took $4 million on its Thursday night in 2018 and went on to open with $45.4 million, about double its forecast, Variety reported.

Daily numbers reveal how a film is playing. Primetime took $8.49 million on its opening Friday, 44% of its $19.2 million weekend, per Box Office Mojo’s daily figures. That points to a front-loaded audience of eager fans.

How much of the money do studios keep?

Not all of it. Box Office Mojo says that on average the distributor receives a little more than half of a film’s final gross, a share often called the “rentals”. The remainder goes to the exhibitor, meaning the cinema. The split varies film by film, and generally favours the distributor in the early weeks before shifting towards the cinema later in the run.

This is why a film can “gross” twice its budget and still not be clearly profitable. The studio receives perhaps half of the gross, and the production budget excludes marketing, which is often not disclosed. Treat claims of profit or flop with care unless a studio or a detailed report sets out the costs.

Records, re-releases and inflation

When you see an “all-time record” headline, check three things:

• Which market: domestic, international or worldwide records are different lists.
• Re-releases: a film’s lifetime gross includes later re-releases. The Avengers: Endgame Encore re-release opened with an estimated $26 million in North America and $86 million worldwide, which left Endgame about $39 million behind Avatar’s all-time worldwide record, as we reported.
• Inflation: most charts use unadjusted dollars, so recent films have an advantage over older ones. Box Office Mojo’s guide points readers to figures adjusted for ticket price inflation and estimated tickets sold, which make comparisons fairer.

Two other ratios often appear in coverage. The multiplier is the total gross divided by the opening weekend; a higher figure suggests strong word of mouth. Per-theatre average is gross divided by the number of locations, which is useful for comparing a limited release with a wide one.

What box office numbers leave out

• Streaming and home viewing: Netflix, for example, does not sell tickets, so it reports views instead. See our Netflix Top 10 explainer.
• Awards eligibility: the Academy has its own theatrical release rules, which are separate from gross. See how Oscar voting works.
• Profit: as above, gross is revenue before the cinema’s share, and before marketing and other costs.
• Currency: worldwide figures are reported in US dollars, so exchange rates affect international totals.
