Well, the budget of NASA is $22.6B/year for all projects combined. And as others have said, this is a small unmanned reusable vehicle, with a few flights under it's belt, after all of the reusable R&D was done for the Space Shuttle.
If I were to lick my finger and lift it into the wind, I'd estimate this flight cost between $0.5B and $1.5B, and most of that would be the gear that they are testing, given that the spacecraft itself is fully reusable.
