your formula would NOT reflect the costs of operation at all.
We (the non-royal kind that hasn't seen HG) don't know the costs of operation because they aren't present in the CRB. Assuming they are somewhat along the lines of all previous versions of Traveller, the costs should be broken down into:
ship mortgage
fuel
crew
life support
docking fees
profit
One thing about modeling all this is that games do a horrible job at modeling real-world events. Even the costs listed above have some huge holes in them. We know that starships can last quite some time (multiple decades, perhaps a century). The performance of a spanking new TL-15 vessel at 1G is the same as that of a TL-12 1G vessel that's 60yrs old. With regular maintenance and refurbishments your TL-12 ship can provide the same level of service as the TL-15 at a fraction of the cost. But that sort of thing isn't modeled. In the real world the price of a ticket to from from NYC to LA remains the same whether or not you are on a 787,777,767,747,737 or an MD-88. Cost to the passenger is on a per-seat basis, and airlines don't modify pricing based upon equipment. They DO, however, sometimes modify the equipment on a route based upon it's profitability and the costs of operating the equipment. How do I know this? Because I spent nearly a year working on creating software for passenger accounting revenue. I learned all kinds of silly rules and regulations related to ticket pricing and airline costs. It's one of the most arcane and silly things you can think of, but that's what everybody in the industry does as the de-facto standard.
We already know from the statements in Traveller that megacorps abound at the Imperial, sector and sub-sector levels. So it's safe to assume that these corporations will act in a manner similar to corporations today. Which means wringing every Cr they can out of shipping and passengers. But if they squeeze too tight they will create a market for competitors. So they should be running efficient (and profitable) routes with pricing that discourages anyone else from swooping in and taking their business. PC's, being non-established drifters, have that ability. Except for the idea that a PC can demand the same pricing that established and scheduled liners and freighters get. That's just silly - at least from a modern perspective. The closest analogy we'd have is a courier service, except their pricing is typically more expensive because it's on-demand and people are paying for time. I can hop on a charter plane and get to LA pretty much at any moment I want. But it's going to cost me $20-30k. If I drive to the airport, buy a ticket and take a regularly scheduled flight I can fly in 1st class for a cool grand. But I might get there a few hours later, so is the 20x cost worth the time savings? Only I can say yes or now to that question.
I'm relatively sure the overall economics haven't been modeled, just some of the basic prices. Which goes back to my argument of too much complex modeling in a game system fails because you can never model it all and still enjoy it as a game. The J-6 passage is out of the pricing range of just about everyone. So most scheduled travel for the average Imperial citizen is going to be in the J-1 through J-4 range. Due to the nature of jump travel ALL multi-system jumps will have to build in generous layover times. So a person who is traveling on 4 jump-1s should spend 2-5 days on a planet or station waiting for the next leg of their trip because the arrival times of a ship cannot be predicted, so all schedules will have to assume the longest travel duration for jump emergence, time to arrive at station/on planet, and then depart.
Which begs the question if this is the case, who pays for the temporary lodging? Is it included in the price of the ticket or is it out of the Travellers pocket? Or do we want to deal with something like that? Is it better to simply hand-wave that sort of complexity out and provide flat-rate costs and be done with it? I think the latter is probably better, but for those PC's who are traveling without a spacecraft, knowing that this sort of thing occurs, gives ref's the background to create mini-adventures with potential time windows.
Another question is what level of detail belongs in the book? Should this be mentioned as background info and let the reader go where they may? Or do we simply not acknowledge it and let people either figure it out, make their own rules, or be blissfully ignorant (until someone else brings it up)?
