The only missed-call number that matters is yours. Pull a normal month of call history, count the calls you could not answer, and follow those callers through to booked work. That gives you a useful baseline without borrowed industry claims.
Build the estimate from your own records
- Count first-time callers that reached voicemail
- Remove spam and existing-customer service calls
- Track how many returned your callback
- Multiply the unreturned qualified calls by your normal booking and close rates
Keep the assumptions visible
Suppose your log shows ten qualified first-time calls that did not connect. If half would normally book an estimate and some of those estimates become jobs, the result is a range, not a promise. Run a low, middle, and high case. Your decisions should still make sense in the low case.
| Input | Use |
|---|---|
| Qualified missed calls | Calls that could have become new work |
| Booking rate | Share that usually accepts the next step |
| Close rate | Share of estimates that become jobs |
| Average gross profit | A better comparison than revenue alone |
Common questions
Should I count every missed call as lost revenue?
No. Some are spam, existing customers, or poor-fit work. Filter the log before doing the math.
