How Much Missed Calls Cost Service Businesses
A practical framework to estimate lost revenue from missed calls and slow callbacks in local service businesses.
Key Takeaways
- 01 Missed calls are not just missed conversations, they are missed booked jobs.
- 02 Estimate leakage by multiplying missed-call volume by average booking value and close rate.
- 03 Speed-to-first-response is one of the highest-leverage metrics for owner-operators.
Most service businesses track ad spend and lead count, but they do not track response leakage.
If a call goes unanswered and no one follows up quickly, that lead often goes to the next provider.
A Simple Revenue Leak Formula
Use this monthly estimate:
Missed Calls x Contact Rate x Close Rate x Average Job Value
Example:
- 120 missed calls
- 45% contacts recovered
- 35% close rate
- $450 average job value
Potential recovered revenue: $8,505/month
Why This Happens
- Teams are in the field and cannot answer
- After-hours calls go to voicemail
- No consistent text-back or callback workflow
- Lead details are incomplete when callbacks happen
What to Measure Weekly
- Missed calls
- First-response time
- Recovery contact rate
- Booking conversion from recovered calls
These four metrics show whether your communication workflow is helping or hurting growth.
