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.
If people living on planets want to engage in interstellar trade, they have to go through the thalassocrats.Assumption, average of 1/2 of retail price goes to shipping cost.Therefore the minimum price of interstellar imported goods are $200 per kilogram.You can alter some of the assumptions yourself to tweak the economy to suit your science fictional background.Merchant Starship Costs Assumption: starships in the interstellar empire are equivalent to present-day jet airliners.That is, assuming a full cargo turnover at each port of call, how many one-way runs can the ship make? From departure planet orbit to FTL flight to arrival planet orbit. Assumption: each trip requires one month for servicing, maintenance, selling the cargo, buying new cargo for the next run.
This makes each trip four months from departure to departure, or three cargos per year.
Don't forget the entry in this website about Cargo Holds As mentioned below, if you want to play around with interstellar trading, or even try doing a full simulation (to do worldbuilding for creating the background of your new novel), I'd suggest getting a copy of GURPS Traveller: Far Trader.
Written with help from a real live economist, this allows one to model interplanetary and interstellar trade with equations and everything.
They go fast, can carry lots of people and cargo, and are the most advanced technology that can be massed produced.
The ticket prices will not be similar between airliners and starships because FTL interstellar travel will probably take more than a few hours for the trip.
Therefore if the cargo was available for free at the origin the minimum selling price at destination is $100,000 per ton, or $100 per kilogram.
