Missed calls
Weekly calls × your missed-call rate. Take both from your phone provider’s call log for a normal week, counting calls that rang out or went to voicemail.

Missed call calculator: see what unanswered calls cost you.
Enter five numbers from your call log and your books. The calculator shows the jobs and revenue that ring out each month, and every assumption is yours to change.
The cost of missed calls is the revenue from callers who wanted to buy and never reached you. Multiply weekly calls by your missed-call rate, the share of those callers ready to book, your close rate, and your average job value. With the example inputs below, $3,250 a month is at risk.

How the missed call calculator works
The calculator follows a missed call from your phone log to your revenue in four steps. No industry averages are built in: every input is an assumption you control, so the result reflects your business.
02
Callers ready to book
Missed calls × the share who wanted to book or buy. Leave out spam, sales pitches, and vendors, and lower the share if many callers try again later.
03
Jobs you would have won
Callers ready to book × your close rate: the share of answered new-customer calls that turn into paid work.
04
Revenue at risk
Lost jobs × your average job value. Monthly figures use 52 weeks ÷ 12 months; yearly figures use 52 weeks.
- The result is revenue, not profit. Multiply it by your gross margin to estimate lost profit.
- Repeat visits, referrals, and reviews from a new customer aren’t counted, so the estimate can understate a customer’s full value.
Worked example: a home service business
These inputs are illustrative assumptions, not benchmarks. They’re the calculator’s starting values, so you can follow each step and then replace them with your own.
| Calls a week | 50 |
|---|---|
| Missed (20%) | 10 calls a week |
| Ready to book (50%) | 5 callers a week |
| Won at a 50% close rate | 2.5 jobs a week |
| Revenue at $300 a job | $750 a week |
| Revenue at risk each month | $3,250 |
| Revenue at risk each year | $39,000 |
That’s about 10.8 jobs a month from 43.3 missed calls. Compare it with InsertChat Pro at $98 a month.
How do you stop losing revenue to missed calls?
Make sure every call reaches someone who can help, even when your team can’t pick up. Route after-hours and unanswered calls to an AI receptionist that answers questions and books appointments, send urgent calls to your team, and rerun this calculator a month later with your new missed-call rate.
Which calls should you count?
Count inbound calls from people who might buy: new customers, booking requests, and questions about your services. Leave out spam, sales pitches, and vendors. Existing customers calling about a booking matter too, but this calculator values new work only, which keeps the result conservative.
Open your phone provider’s call log or call reports and divide missed or unanswered inbound calls by total inbound calls for the same week. Count calls that rang out or reached voicemail. If your provider doesn’t report it, tally a typical week by hand.
Yes. A voicemail is still a call nobody answered. If you return voicemails quickly and still win most of those jobs, lower the share of callers ready to book so the result matches what you see.
Use the share of answered new-customer calls that turn into paid work, from your CRM or booking records. If you don’t track it, count last month’s new-customer calls and the jobs they produced. The calculator’s 50% is an example, not a benchmark.
No. It’s the revenue those jobs would have brought in. To estimate lost profit, multiply the result by your gross margin. The calculator also leaves out repeat visits and referrals, so it can understate what a new customer is worth.
It answers the calls your team can’t take, after hours or when the line is busy. InsertChat answers from your business knowledge, books appointments into your calendar, takes details for a callback, and alerts your team to urgent calls, with every conversation in one inbox.
InsertChat Pro is $98 a month with 5,000 AI credits shared by calls and written conversations. Calls round up to whole minutes. Compare that with your monthly result, or use the receptionist cost calculator to estimate the credits your calls need.
