Owning a TARDIS is like having access to a timeshare anywhere in space and time. It's a valuable commodity, but just how valuable? The speculative bean counters at Centives have decided to take a crack at figuring out how just how much one month's rent on the TARDIS would be.

On the heels of estimating how much it would cost to build the Death Star, Centives is back at it, this time turning their calculators on the Whoniverse. They look at how much a luxury hotel room, ready helicopter service, and other services similar to the TARDIS would cost for a year's time.

Of course, they can't quite calculate some of the TARDIS's more unpredictable powers (like granting the occasional bout of immortality), and some of their real-world examples aren't quite analogous. They use a trip on Virgin Galactic (which doesn't quite equate to visiting alien civilizations) to find the value of going to space, and they use cryogenic freezing as a proxy for time travel, even though it's one-way and doesn't return you safely to your bed five minutes after you left. So their estimate, while a strong effort, is grossly conservative:

In total then? We think that the market value of hiring the TARDIS would be Â£15,140,064 or $23,930,385 or 504,668,800 jelly babies.

They point out that, for that much money, James Bond could rent a fleet of 76 Aston Martins.
