SpaceX COO Gwynne Shotwell compared Falcon's cost of low orbit "on the order of $80 million to $90 million" and "$150 million to $160 million" for a Falcon Heavy with all the trimmings. "In contrast, ULA charges taxpayers $400 million every time it launches a rocket into space." SpaceX's math gives you the 75%. The rest is arguing about whether SpaceX minimized the actual deliveries to arrive at that the $400 million per launch price.
