Before buying anything, pull one month of call logs from your phone system. You need six numbers, and most practices are surprised by at least three of them.
- Missed-call rate — unanswered ÷ total inbound.
- Average answer speed — rings before pickup. Past four rings, abandonment climbs sharply.
- After-hours share — calls outside published hours, including weekends.
- Booking rate on answered calls — the ceiling on everything else.
- Abandonment during hold — callers who hung up while waiting.
- Revenue per answered new-patient call — first-year production ÷ new patients booked.
Multiply the missed-call count by your new-patient mix and revenue per call and you have the size of the problem in dollars. The missed-call revenue calculator does the arithmetic.
