How the numbers are derived, what the assumptions are, and what to do with the result.
Industry data from telecoms research consistently shows that 60–80% of callers who reach voicemail never leave a message and never call back. The exact rate depends on industry urgency — emergency services and healthcare are higher; B2B SaaS is lower.
When a call goes unanswered, GoHighLevel sends an automatic SMS within seconds acknowledging the missed call and inviting the caller to reply or book. This keeps the conversation alive and routes the lead into a Conversation AI flow that qualifies and books without waiting for a human.
The calculator is most impactful for appointment-driven businesses — med spas, law firms, home services, dental practices — where a missed inbound call is a direct missed booking. Businesses that primarily generate leads through forms get more value from the Lost Lead Revenue Calculator instead.
