The calculator uses industry benchmarks from plumbing business surveys. The formula is: missed calls per day = daily calls x (1 - answer rate). Annual revenue = missed calls x average job value x close rate x 365. Your actual numbers will vary based on your market and service type.
What's a typical call answer rate for plumbers?
Industry data suggests most plumbing businesses answer 65-75% of inbound calls. The rest go to voicemail - and most customers don't leave messages; they call the next contractor.
What's a realistic close rate from inbound calls?
For inbound calls from customers actively looking for a plumber, 45-65% is typical. Emergency calls close higher (70-80%). Calls from paid lead platforms close lower (20-40%) because the lead is shared with competitors.
Does this include emergency/after-hours calls?
Use your total inbound call volume including emergency calls. If you offer 24/7 service, your actual missed call rate is likely lower. If you don't take after-hours calls at all, your missed revenue figure may be understated.
