If a person plus their luggage is less than that, taking into account food consumption and life support, the cost of moving to Mars could ultimately drop below $100,000.

Cost will be brought down 5 million percent with
* fully reusable rocket
* orbital refueling
* Propellent production on Mars
* CH4 / O2 DEEP-CRYO Methalox fuel

The Spacex ITS (Interplanetary Transport Systme) rocket booster is really a scaled-up version of the Falcon 9 booster. There are a lot of similarities, such as the grid fins and clustering a lot of engines at the base. The big differences are that the primary structure is an advanced form of carbon fiber as opposed to aluminum lithium, we use autogenous pressurization, and we get rid of the helium and the nitrogen.

Spcex has been able to optimize the propellant needed for boost back and landing to get it down to about 7% of the lift-off propellant load. With some optimization, maybe we can get it down to about 6%.
