How the calculator works
The calculator multiplies your weekly call volume by 4.3 weeks to get a monthly figure, applies your miss rate to find lost calls, then applies your booking conversion rate to estimate jobs lost. Each lost job is multiplied by your average job value. This is a conservative estimate — it doesn't account for repeat customers or referrals lost alongside each missed job.
Our client data shows that when callers reach a live voice immediately — even at 11 PM — roughly 85% of previously missed callers book a job or stay on the line to schedule a callback. Callers who hit voicemail have an average callback rate under 30%. The difference is urgency: home service customers call because they need help now, not later.
Any call that goes to voicemail, rings without answer, or receives a "we're closed" message. This includes after-hours calls (typically 6 PM–8 AM), calls during peak hours when all staff are on other lines, and calls on weekends when most small service businesses have no live coverage. For a typical contractor, 25–45% of inbound calls fall into this category.
A full-time receptionist costs $35,000–$50,000/year and covers ~40 hours/week. Calling Matrix Starter starts at $447/month billed annually ($5,364/year) — or $497/month on monthly billing — and covers 168 hours/week. The AI doesn't call in sick, doesn't need retraining when your services change, and handles every call the same way every time.
Calling Matrix Starter starts at $497/month on monthly billing, or $447/month billed annually — setup fee waived on annual. No per-minute charges. See the full pricing breakdown at callingmatrix.com/pricing.
