NASA paid $1.6 billion for 12 launches, that's a lot more than $57 million per launch.
Then you said
Thats because NASA was buying into a company that didn't have the capability at the time and knew they would be funding development.
So, I replied
In the end the cost for a supply mission is $90 million for Falcon 9 v1.1 plus the cost of using Dragon: I doubt it will ever be significantly less than the actual $133.3 million.
And now you say
You cannot add in the cost of the Dragon when calculating the launch cost of a launching system.
Why not? Because it doesn't suit the mantra that SpaceX is so cheaper than the alternatives? The cost of a resupply mission will never be cheaper than what it is now, let alone near to the famous $57 million, and the fact that the contract was prolonged for an undisclosed price proves this. That's a fact.
It also isn't really relevant what NASA paid SpaceX for the contract. An Iphone doesn't cost $700 but customers still pay that. In the end the launch costs is somewhere south of the $60m private customer cost.
It is relevant, unless you want to compare apples to oranges. Other vectors include insurance and services in the total cost, when SpaceX says $61 million does not ($57 million is the old cost for the Falcon 9 v1.0). US government requires insurance and all that, so the cost is about $90 million (per launch, not including Dragon), not $60 million: for example Vega rockets cost €32 million services included, but €25 to €22 million is the cost excluding services.
