The calculator uses $200 — the midpoint of that range — when you choose a hired service.
Midpoint of the typical advertised price range for national commercial registered-agent services as of July 2026 (e.g. Northwest Registered Agent $125/yr, ZenBusiness $199/yr, LegalZoom $249/yr). Budget providers advertise below this range and premium corporate-service firms above it. Serving as your own agent costs $0 where you meet state eligibility rules.
