If Earth is worth 5 quadrillion dollars, and it is divided evenly between all members of said planet, we each would receive 680,549.88 (six hundred and eighty thousand five hundred and fourty nine dollars and eighty eight cents). That is based off of 2015 earth population of 7.347 billion humans. Maybe we can increase the value of Earth by terraforming the ocean into habitable land. It would be much easier than making mars habitable.
