How the Missed Call Revenue Calculator Works
The calculator uses a simple formula: your missed calls per week multiplied by 52 weeks, then multiplied by your average sale value and your close rate. The result is a realistic estimate of the annual revenue leaving your business through unanswered calls.
The default values (10 missed calls per week, $500 average sale, 25% close rate) reflect typical numbers for local service businesses like home services, medical practices, contractors, and law firms. Your actual numbers may be higher or lower, and adjusting the inputs shows you your specific exposure.
What Counts as a Missed Call?
A missed call is any inbound call that does not reach a person or a qualified booking system. This includes calls that go to voicemail, calls that ring and disconnect, and calls answered by an untrained person who does not book the caller. Industry research suggests that 80% of callers who reach voicemail do not leave a message and do not call back.
What Is a Realistic Close Rate?
Close rates vary widely by industry and by the quality of your intake process. Home service businesses that answer calls quickly typically close 30% to 50% of new inquiries. Medical and legal practices often close 15% to 30%. If you do not know your close rate, start with 25% as a reasonable estimate.
Why Does This Matter?
The revenue you see in the calculator is not theoretical. It is real money your business is producing demand for but failing to capture. Every business that answers instead of routes to voicemail captures some of that revenue. The question is not whether missed calls cost you money. It is how much you are willing to keep losing before you fix it.
