In cinema ticket sales, the price is split between the cinema and the production company (this is why concessions cost so much, it's the cinema's lifeline). The split is in the studios favour the earlier in the run and adjusts each week to be more even and then in the cinema's favour.
So, to make a production budget back, a film typically needs to take roughly twice what it cost in ticket sales once you take away the cinema's cut.
The film's marketing budget is then normally equal to or a significant portion of the production market. So, to break even for production and marketing costs, and taking into account the cinema's cut, the film needs to take, as rule of thumb, 3x production budget.
As a licensee, Sony then also have to pay Marvel a cut. This is why Amazing Spider-Man 2 was a crap money maker for them because Marvel's cut was so significant, it reduced their profit to single digits millions. I don't know if the current co-production for Spider-man deal affects Venom and Morbius et al, but Marvel will still have a cut, so takings of approx 3.5-4x production budget for a comfortable take home for Sony sounds reasonable.
