Missed Call Revenue Calculator
How much do unanswered calls cost your business each month? Enter your weekly call volume, missed-call rate, booking rate and average job value to see the revenue walking out the door.
Every service business misses calls. You're on a roof, under a sink, driving between jobs — and the phone rings out. Most owners have a rough sense that it costs them something. Almost none have put a number on it.
This calculator does. Put in how many calls you get in a week, how many go unanswered, how many answered calls turn into booked work, and what a typical job is worth. It shows what those missed calls are worth a month and a year. No signup, nothing stored.
Missed calls × booking rate × job value. Weeks are converted to months at 52 ÷ 12. Nothing you enter leaves your browser.
This ran on the numbers you typed. The product runs on your actual calls, chats and emails.

- 01
Calls per week
Count inbound calls, not outbound. If you don't know, your phone provider's call log or your last bill will tell you. A two-truck HVAC shop typically sees 60–150 a week in season.
- 02
Share that go unanswered
Include calls that go to voicemail — most callers who reach voicemail don't leave one, they call the next listing. Industry surveys put the unanswered share for small service businesses between 20% and 40%.
- 03
Booking rate on answered calls
Of the calls someone does pick up, how many become a scheduled job or estimate? For emergency trades it's high — 40–60%. For quotes and comparison shoppers, lower.
- 04
Average job value
Use your real average ticket, not your best day. For plumbing and electrical service calls it's often $250–$600; for HVAC repairs and installs, considerably more.
