What are missed calls actually costing you?
Two numbers in — your daily call volume and your average job — and this calculator estimates the revenue walking out the door while you're on a ladder, under a sink, or asleep. Built on published response-speed research, not hype.

The rest are existing customers, suppliers, and spam — you don't lose that work to slow response.
Of the new leads you actually reach quickly — the ones that book with you.
A directional estimate built from published benchmarks and your inputs — not a guarantee. The sliders are yours; the math is open below.
How this math works
- New leads a year = daily calls × 365 × (new-customer share of calls).
- Slow or missed responses = new leads × 57.1% — the study benchmark for first call attempts that happen more than a week after the lead came in.
- Conversion gap — leads contacted within minutes convert at roughly 8x the rate of leads left waiting. We credit your week-late leads your close rate ÷ 8.
- Lost jobs = slow-or-missed leads × (your close rate − your close rate ÷ 8). Lost revenue = lost jobs × average job value.
Response-speed figures are from two studies: the 100x contact odds from the 2007 Lead Response Management study by James Oldroyd with MIT and InsideSales.com, and the ~8x conversion and 57.1% week-late first attempts from InsideSales.com's 2021 analysis of 5.7 million inbound leads at 400+ companies. Your inputs and assumptions fill in the rest.
Homeowners don't pick the best shop. They pick the first one that answers.
You already know the moment: the call comes in while you're halfway up a ladder, and by the time you call back, they've booked the other shop. The research says that moment happens constantly — and it compounds.
The odds of connecting
Respond within 5 minutes instead of 30, and the odds of actually connecting with that lead are 100 times higher.

More than half of first call attempts to a new lead happen over a week after it came in. For most shops, "I'll call back later" is the default setting.

Your estimate: $82,063 a year slipping by. Recovering even 10% of it is $8,206 against a plan that starts at $49/month — about 14x. Recover half and it stops being a line item. That's what a 60-second response is worth in your trade.

Frequently asked questions
How is the lead loss estimate calculated?
New leads a year is your daily call volume times 365 times your new-customer share of calls. We apply the 57.1% week-late-or-never benchmark to estimate how many get a slow response, then credit those leads your close rate divided by 8 instead of your full close rate. The difference, times your average job value, is the estimated lost revenue.
Where do the response-speed numbers come from?
The 100x contact-odds, ~8x conversion gap, and 57.1% week-late figures are from the Lead Response Management study by James Oldroyd with MIT and InsideSales.com, expanded across 5.7 million inbound leads at 400+ companies. The 23.1% figure is from SeenOnMain's own audit of 1,965 home-service business websites across 30 U.S. metros, August 2026.
