NASA pays the Russian space agency Roscosmos about $81 million and change for a round-trip ticket in a Soyuz capsule. The latest five seats NASA bought in bulk were a little cheaper, about $74.7 million per seat. NASA estimates that a round-trip ticket to the ISS on the SpaceX Crew Dragon or the Boeing CST-100 Starliner would cost about $58 million.

In Verge, Space Adventures said the price for a trip around the moon is more than double the current cost of a trip to the ISS: about $175 million dollars per seat.
