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 million (not counting fuel, landing fees, and taxes).An airliner's purchase price is 0 million so one year's uses costs about one-third of the purchase price.With creative maintenance, the service life might be longer than 30 years, see below.Question: how many cargos can a merchant starship carry in 1 year?Assumption: starship purchase price will only be about

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.With creative maintenance, the service life might be longer than 30 years, see below.Question: how many cargos can a merchant starship carry in 1 year?Assumption: starship purchase price will only be about $1 million per ton of cargo capacity instead of $2 million, because starships are orbit-to-orbit, need no landing gear, need no wings, can use lighter structure because they accelerate under 1 g, and we will assume they can carry twice as much cargo per deadweight (inert mass) as a cargo jet.Assumption: cargo starship operating cost is similar to cargo jet.

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

So the starship initial purchase price is about 1/10th of the overall lifetime service cost ($1 million / (30 * $300,000)).

Actually it will be closer to 1/5th due to the interest on the purchase loan.
