If you compare with other similar naval projects, the program for 12 units of Slava sized destroyers, with a displacement of around 10,000+ tons, would likely bring the costs somewhere between $10-20 billion. I wouldn't be surprised if the unit cost would be $1-2 billion a ship similar to Burkes and other heavy destroyers. It's unlikely to be as expensive as the CG(X) or the Zumwalt programs where it was around $3.4 billion a unit. Costs will still depend on how radical the design is but Leader is likely going be a conventionally structured stealth ship if its anything like the proposed concepts of the Severnoye Design Bereau.
