How much do 3D ticket prices affect gross revenue?

Firstly, it's important to note that 3D cinema is unquestionably in decline. Box office takings suggest that 3D ticket sales have been receding since Avatar, which is a consumer behaviour that puts 3D cinema aligned with little more than a fad, an certainly an outgoing trend.

Whilst the above link only explores UK box office, this shouldn't be seen as limiting in its scope: the UK is often used as a testing ground for new cinema technology, as it's a smaller market that creates more predictable results to be extrapolated across other territories: consumer behaviour in the UK is often a dependable trendsetter.

Those figures would suggest that on average only 18% of a films revenue can be attributed to 3D sales. We can work out how any tickets that equates to in your example, Jurassic World.

World Wide Gross = $1,561,318,770

I'm unfamiliar with average 3D ticket prices and their comparison to 2D in anywhere but the UK, so I'm going to have to exchange currency with Sterling (£) and hope the costs are similar when converting back to USD ($).Obviously all these working out are using averages so will not be accurate, but representative of what industry trends would suggest based on known variables.

So $1,561,318,770 = £1,007,705,517 at current exchange rate.

18% of this (total 3D revenue) would be £181,386,993.

Actual 'Bums on seats' Sales:

If the average 3D ticket in the UK is £10, its an easy calculation that 18 Million 3D tickets were sold for Jurassic World, worldwide.

Compare this to 2D Sales (82% of total gross) = £826,318,524

Divided by average ticket cost of only £6, gives 137,719,754 2D tickets sold.

So, despite Box Office takings, the total amount of cinema audience who chose to see Jurassic World in 3D equates to around:

8%

We should also factor in the additional costs of making a 3D film when weighing up the income gained.

The difference in production cost between a 2D and 3D film is something still not openly discussed by studios, but it's safe to assume it's considerable.

There are two ways to produce a 3D film: shooting stereoscopically, and post-production conversion.

Conversion is the cheapest and nastiest way, and certainly not how Jurassic World was shot: I only include cost speculations here for comparison and rule of thumb for interested parties.

Conversion to 3D is rumoured to cost between $100,000 - $120,000 per minute: but lets be generous and put it at the lower end of that scale, which converts to £64,576 per minute.

Jurassic World has a run time of 2hrs 5 mins, or 125mins.

So £64,576 X 125 = £8,072,000 (pre-box office cost of 3D)

£181,386,993 - £8,072,000 = £173.314993 million (True profit from 3D sales, est.) or $267.54M

Jurassic World was shot using stereoscopic camera's, which (as Invalid_id has pointed out previously) is a technique said to cost 2-4x more than conventional 2D filming.

Jurassic World's pre P&P budget is estimated at $150 Million, so we'll jump down the middle and say the actual production cost (excluding salaries etc.) would have been 60% cheaper should they have shot using only 2D.

That's a cost of $90,000,000 to make the film 3D.

In conclusion, the net financial gain from shooting Jurassic World in 3D is

$190M

($279842038.93 - $90M).
