Assumption: starship fuel is cheaper than cargo jet JP-4 fuel.

Big assumption since JP-4 is about $1.39 per gallon.(ed note: starships are going to require lots of infrastructure.)Assumption: the service life of a merchant starship is 30 years.

Assumption, average of 1/2 of retail price goes to shipping cost.

Using a long series of estimations whose details can be found in Rick's article he concludes that the annual operating cost for an airliner is about $30 million (not counting fuel, landing fees, and taxes).

An airliner's purchase price is $100 million so one year's uses costs about one-third of the purchase price.

Therefore the starships will do fewer trips per year than airliners, so the starship passenger ticket price (and cargo waybill) will have to cover a larger share of the starship's yearly expense.

For comparison purposes we need an airliner's average cost of running, but the corporations are remarkably closed-lipped about that.

This means the ship owner must earn $100,000 of profit per ton of cargo.

That is, selling price at destination MINUS purchase price at origin must be 0,000 or more.

A cargo jet can carry 50 tons so its purchase price is about million per ton of cargo capacity.

Assumption: starships are strictly orbit-to-orbit, they use space ferrys to transfer passengers and cargo between the starship and the planet.

Sometimes these trader cultures in large clan-ships have a Thalassocracy, where they have a monopoly on trade since they control all access to space.

If people living on planets want to engage in interstellar trade, they have to go through the thalassocrats.

With creative maintenance, the service life might be longer than 30 years, see below.
