Default Fixing the Economics

The prices for transport in MGT are BADLY broken. (Not even going to the spec trade side of things.

I cranked out a spreadsheet with budget boxes (but not skimpy-crew, albeit only 1 pilot, 1 nav, std engineers, no medic, 1 gunner, no stewards) to figure out base cargo costs. I used 200, 400, 600, 800, 1000, 1200, 1400, 1600, 1800, and 2000 Td Ships. None are fitted for passengers. Financed value is 100%. Maintenance per half-month, annual payment per half-month, fuel per jump, salaries per half-month.

I got the following landmarks for cost per Td of cargo:

Jump ____ J1 _______ J2 _______ J3 _______ J4 ________ J5 _________ J6 __
Max ____ 699.96 _ 1,316.77 _ 2,432.97 _ 5,157.50 _ 19,026.67 _ 111,265.74
Avg ____ 645.14 _ 1,159.88 _ 2,022.08 _ 3,768.07 __ 9,322.59 __ 70,703.81
Min ____ 538.16 _ 1,050.15 _ 1,903.51 _ 3,396.43 __ 7,311.50 __ 44,323.65
Median _ 646.07 _ 1,156.44 _ 1,992.19 _ 3,610.38 __ 8,053.17 __ 61,072.32
StDev ___ 42.79 ____ 68.62 ___ 152.75 ___ 517.31 __ 3,543.95 __ 25,387.21


A couple notes: For J1 and J2, 400Td is the optimal hull; for J3-J6 2000Td is. Figured that irony should be shared.

This means that a good price per ton for shipping cargo should be on the order of:


Basal Ton Cost ____ 687.93 _ 1,228.50 _ 2,174.83 _ 4,285.37 _ 12,866.54 _ 96,091.03
Round to next 100 _ 700.00 _ 1,300.00 _ 2,200.00 _ 4,300.00 _ 12,900.00 _ 96,100.00


Basal cost is the lower of (minimum + 2 StDev) or (Average + StDev)… and means a profit for those in optimized hulls.

Now, Mid Passengers Single occupancy, presuming a level 1 steward, should be 4.4 cargo tons equivalent (CTE) each (4 for pass, 0.4 for steward SR), plus KCr4.425 (2 for PassLS, 0.2 for Steward LS, 0.1 for 1/20 monthly salary, 2.125 for increased maintenance and payment)

Single occupancy high passengers: 6 CTE (4 for SR, 1 for steward SR, 1 for Passenger's cargo ton) plus KCr4.875 (2 for pass LS, 0.5 for steward LS, 0.25 for 1/8 monthly salary, and again, 2.125 for increased maintenance and payment.)

Double Occupancy Low:
2.4 CTE (half a stateroom, but a share of the steward @ SO)
+KCr 2.6625 (1.5+0.1+1.0625)

Double occupancy high:
4 CTE (2T SR, + 1T StewSR, +1 Cargo Ton)
+KCr2.8125 (1.5+.25+1.0625)



_________________ J1 ________ J2 ________ J3 ________ J4 ________ J5 _________ J6 __
Basal Ton Cost _ 687.93 __ 1,228.50 __ 2,174.83 __ 4,285.37 _ 12,866.54 __ 96,091.03
MP, SO _______ 7,451.88 __ 9,830.42 _ 13,994.24 _ 23,280.64 _ 61,037.78 _ 427,225.52
MP, DO _______ 4,313.52 __ 5,610.91 __ 7,882.09 _ 12,947.40 _ 33,542.20 _ 233,280.97
HP, SO _______ 9,002.56 _ 12,246.03 _ 17,923.97 _ 30,587.24 _ 82,074.25 _ 581,421.16
HP, DO _______ 5,564.21 __ 7,726.52 _ 11,511.81 _ 19,953.99 _ 54,278.66 _ 387,176.61


But, since those numbers are ugly, let's round passengers to the nearest Cr100 for J1-3, and Cr1000 for J4-6, and use the rounded basal


_____________________ J1 ________ J2 ________ J3 ________ J4 ________ J5 _________ J6 __
Round to next 100 __ 700.00 __ 1,300.00 __ 2,200.00 __ 4,300.00 _ 12,900.00 __ 96,100.00
MP, SO ___________ 7,500.00 __ 9,800.00 _ 14,000.00 _ 23,000.00 _ 61,000.00 _ 427,000.00
MP, DO ___________ 4,300.00 __ 5,600.00 __ 7,900.00 _ 13,000.00 _ 34,000.00 _ 233,000.00
HP, SO ___________ 9,000.00 _ 12,200.00 _ 17,900.00 _ 31,000.00 _ 82,000.00 _ 581,000.00
HP, DO ___________ 5,600.00 __ 7,700.00 _ 11,500.00 _ 20,000.00 _ 54,000.00 _ 387,000.00


Massaging them for love of round numbers or half-rounds (bt not cargo below J5 - just passenger fares)

_____________________ J1 ________ J2 ________ J3 ________ J4 ________ J5 _________ J6 __
Round to next 100 __ 700.00 __ 1,300.00 __ 2,200.00 __ 4,300.00 _ 13,000.00 __ 96,000.00
MP, SO ___________ 7,500.00 _ 10,000.00 _ 14,000.00 _ 23,000.00 _ 65,000.00 _ 430,000.00
MP, DO ___________ 4,500.00 __ 6,000.00 __ 8,000.00 _ 13,000.00 _ 35,000.00 _ 235,000.00
HP, SO ___________ 9,000.00 _ 12,000.00 _ 18,000.00 _ 31,000.00 _ 85,000.00 _ 585,000.00
HP, DO ___________ 6,000.00 __ 8,000.00 _ 12,000.00 _ 20,000.00 _ 55,000.00 _ 390,000.00


Now we have some workable numbers. Profit is slim; it can be raised by more down payment, reducing crew salaries to profit shares, having better stewards, or reducing fuel costs from refined to unrefined.

Interesting. Jump-1 is almost competitive with jump-2 and is competitive with jump-3, while jump-4 is significantly less competitive. What are the design differences that causes that?

It's the proportional losses, and the non-linear expansions

for 1Jn and 2weeks Pn, counting just JD/PP/JFuel/PFuel:
J1P1 is 6T+(15% Hull)
J2P2 is 6T+(30% Hull)
J3P3 is 6T+(45% Hull)
J4P4 is 6T+(60% Hull)
J5P5 is 6T+(75% Hull)
J6P6 is 6T+(90% Hull)

Average cost per ton-parsec:
J1 645.14
J2 579.94
j3 674.03
J4 942.02
J5 1,864.52
J6 11,783.97

Here's the raw data visually:

Edit:bottom line is J1, then J2, J3 J4, j5, and top, J6

The hiccups are due to bridge and crew thresholds.

Baseline total "dead tonnage" for cargo is
12 Pilot, Nav, gunner Staterooms
01 Turret (for mail)
05 Jump Drive
01 PP
-1 MD (except at Drive A)
40 Bridge (tho below 1001, it's 20, and below 201 it's 10)

I like MGT trade; it's the only one I've ever actually understood.

Trade itself isn't broken, only freight & pax pricing.

He's saying that traders don't get enough money for shipping freight and passengers to meet expenses, except (perhaps) for Jump-1 ships. Others go broke, fast.

Exactly.

Plus that the speculation system provides sufficient variability in both core prices and world-to-world differences that one can make a profit on stuff for ships up to J3 to make a profit; J4 is iffy.

Default Thank you, Aramis!

Your analysis of the in-game issue for economics proved my original point several posts ago. At the time, while ostensibly trying to figure our the expenditures versus profit for both Serenity and Traveller, the more demanding question posited the following: "how do you stay ahead of the repo man with costs and trade so completely incongruous to one another." Again, I get the "having to make money to make the mortgage" hook in the game ~ but, if the players are that concerned about making their 'nut' every single month...that will get old, very fast.
