Current estimates are that space colonists would need about 17 tons per person for their share of space station habitat. The cheapest advertised price today for delivering mass to orbit is the Falcon Heavy, in development, at $90 million for 53 tons to LEO [SpaceX 2015], or $1.7 million per ton. For 17 tons that is about $29 million. Combining these two costs gives us (rounding up) $60 million per person. This does not include materials, construction or resupply costs. It would be assumed that government or space tourism businesses will conduct most of the research and development cost other than actually building a settlement.
