There was an internal SpaceX presentation video which was leaked to r/SpaceX that stated their launch cost to be $30 million per launch. The video was taken down later that day, but that's the currently best known number for how much a fully loaded reusable Falcon 9 launch costs.

Thanks for the reference, I missed that.

I know one way or another that SpaceX's internal launch costs are a lot lower than the others. Good stuff.
