It gives you average cost per flight, which is the number you should use
for programmatic trades. Marginal cost is only useful for figuring out
which vehicle to use for a specific flight.

Apollo was ~$90 billion adjusted for inflation for the Saturn V ($50 billion) and CSM ($37 billion) and yet we’re up in arms over the same capability as that for about half the price (SLS being $27 billion and Orion being $24 billion).
Need I add that NASA’s budget is still significantly less than half what it was at the height of Apollo despite enjoying record public enthusiasm.
PS - contract cost divided by number of units always distorts the marginal cost and it’s a mistake I see across the board.

SLS, presumably. Is anyone shocked? ~$4 billion a year program
budget, ~one flight a year, let's see, divide 4 by 1... However
the SLS establishment massaged the numbers, that's what it was
always going to work out to.
Ignoring the huge development costs, of course. I've lost
track. How many tens of billions have been sunk into this thing
over the years? With or without its Ares predecessor, it's a
very large number.
