Instrument 01 · missed calls
Revenue does not walk out.
It rings out.
The homeowner who reaches voicemail may book the next contractor before you call back. Four numbers, all editable, estimate what that risks this year. No quote, no sales call.

What a typical sold job brings in, in revenue, not profit.
Seeded from the roofing starting figure. Not your real rate until you set it.
Estimated annual revenue at risk from unanswered calls
$280,800
That is 15 unanswered qualified calls a week at a $1,200 job, every week of the year, at the 30% close rate you set for roofing. An estimate from your inputs, not a forecast or a guarantee.
Catch even half and about $140,400 comes back through the door this year. An illustration of what recovery is worth, never a guarantee.
The math, in full
annual = 15 calls × 52 weeks × $1,200 × 30% close rate
recovered = annual × 50%, shown only as "if you caught even half"
This is an estimate from your four numbers, not a quote.
Reference figures, not calculation inputs
27% of calls to home-services businesses go unanswered.
Invoca, 2024Typical shops book about 42% of the calls they answer.
ServiceTitan data, 3,000+ trade businesses, 2022Published estimates run as high as $1,200 per missed call.
Housecall Pro, 2024The calculator above does not use these figures. It uses the four inputs you set. Where this site references a per-call figure, we assume $200 to $500 and stay under the published estimates.
A missed call is an operations problem wearing a phone problem's clothes.
The same gap that drops a homeowner's call drops a submittal, a COI, a progress invoice. The front desk is buried exactly when call volume peaks, and a voicemail with no owner quietly becomes a lost job. The fix is not a smarter phone. It is a 7 PM ring landing on a named owner while it still matters, inside one workflow from call to job to invoice.
The leak this calculator cannot measure.
For commercial operators, the bid you lose is rarely to a missed call. It is a COI that arrived a day late, a submittal that sat in an inbox, a progress invoice that slipped a cycle. That cost is real and it does not fit three fields, so we map it on a call instead.
