What's the cost of a provisional patent?

A US provisional patent application costs $65 to $325 in USPTO fees depending on entity status, plus $1,500 to $3,000 for professional drafting if you want more than a bare-bones disclosure. The USPTO fee alone is low, but a poorly drafted provisional creates a false sense of security since it only protects what it actually discloses.
