The 90/10 Split and the House Nut: How Movie Theaters and Studios Divide Box Office Revenue

The next time you wince at the $18 price tag for a large popcorn and a soda, know that you are not just buying snacks—you are paying the only bill that actually keeps the lights on in the building. The American movie theater has effectively ceased to be in the business of selling movies. Instead, it is a high-volume concession stand that uses multi-million-dollar Hollywood spectacles as a loss leader to get you through the door. This economic reality is the direct result of a quiet but total overhaul in how studios and exhibitors divide the billions of dollars generated at the box office.

Historically, the relationship between the people who make movies and the people who show them was governed by a complex, time-sensitive formula known as the sliding scale. When a highly anticipated film arrived, the theater was allowed to deduct a fixed sum from the gross ticket sales before sending a dime back to Los Angeles. This baseline figure, affectionately known in the industry as the "house nut," was calculated to cover the theater's weekly operating expenses: rent, electricity, projectionist salaries, and the ushers sweeping up spilled candy.[1]

Once the house nut was cleared, the remaining revenue was split between the studio and the exhibitor. Under the traditional sliding scale, the studio took a massive cut—often 90%—during the opening weekend. But as the weeks wore on and the crowds thinned, the math flipped. By week four or five, the theater might be keeping 80% of the ticket sales. This system incentivized theaters to hold onto successful films for months, turning late-run screenings into pure profit centers for the local multiplex.[1][2]

That model is now effectively dead. Today, the major Hollywood distributors have largely replaced the sliding scale with what is known as an aggregate deal. Rather than shifting the percentages week by week, the studio and the theater agree to a flat, mutually determined split for the entire run of the film. "The most common is the aggregate deal where total box office revenue that a given film generates is split by a pre-determined mutually-agreed percentage between distributor and movie theater," according to standard distribution contracts. While the exact numbers are fiercely guarded trade secrets, the aggregate split typically hovers around 50/50 or 55/45 in favor of the studio, regardless of whether the ticket is sold on opening night or two months later.[3][4]

The shift to the aggregate scale fundamentally altered the survival mechanics of the exhibition business. By flattening the revenue curve, studios eliminated the late-run profit tail that theaters used to bank on. If a theater is only keeping 45% to 50% of a ticket sale in week five, the box office revenue alone is rarely enough to clear the house nut. The math simply does not work without the concession stand.[2]

This is why the modern multiplex is designed to funnel you past the candy counter. The profit margins on popcorn and fountain drinks routinely exceed 80%, making them the true economic engine of the exhibition industry. When a studio demands a higher aggregate cut or imposes strict per-capita minimums, the theater has no choice but to lean even harder on concessions to make up the difference. When Disney tried to establish a per-capita model aligned with the average national movie ticket price in 2015, John Fithian, the chief executive officer of the National Association of Theatre Owners, noted that his organization received "an avalanche of complaints, confers and fears" from exhibitors.

The tension between studios and theaters is further complicated by the shrinking theatrical window. Before the streaming era, a movie might play exclusively in theaters for 90 days or more, giving exhibitors ample time to maximize their share of the aggregate split. Today, that window has collapsed. Many films hit premium video-on-demand (PVOD) or streaming services just 17 to 45 days after their theatrical debut.

When a movie moves to home screens while it is still playing in theaters, the exhibitor loses its monopoly on the audience. The studios, meanwhile, capture 100% of the revenue from their proprietary streaming platforms or take a much larger cut from digital rentals. This dynamic has forced theaters to adapt, leading to the rise of premium large-format screens, dine-in cinemas, and subscription models like AMC Stubs A-List, all designed to make the physical act of going to the movies an experience that cannot be replicated on a living room couch.[3]

The National Association of Theatre Owners (NATO)—which rebranded as Cinema United in 2025—has spent years pushing back against studio demands that squeeze exhibitor margins. The trade group, which represents over 35,000 screens in the United States, frequently lobbies for longer theatrical windows and more favorable rental terms. But their leverage is limited when facing off against consolidated media conglomerates that control the supply of blockbuster intellectual property.[4]

The financial architecture of the box office is a zero-sum game, and the studios are currently holding the winning hand. As long as the aggregate scale remains the industry standard, the local movie theater will continue to operate on razor-thin margins, entirely dependent on the audience's willingness to buy a bucket of popcorn. The next time a theater chain reports its quarterly earnings, look past the box office grosses and focus on the food and beverage revenue—that is where the real story of the exhibition business is written.
