Annual revenue lost
Missed calls × close rate × average job value × 12 months. The product of four numbers you already know — the only unknown is how long you keep losing them.
ROI calculator
Your three numbers in — annual revenue lost and recovered jobs out.What are missed calls
costing you per year?
Three inputs: how many calls you miss in a typical month, what a closed job is worth, and your current close rate. The calculator does the rest — and updates on every keystroke, so you can see exactly how the number moves when you fix one variable.
The headline figure
Solo rooferAverage annual revenue lost
$45,600
10 missed calls/mo × 40% close rate × $9,500 average job × 12 months — the same math the calculator below uses when you click the Solo roofer preset.

Outputs update on every keystroke — change a preset, retype a field, or step one variable at a time. The default is a solo roofing contractor, the same shape every other page on this site uses to publish the $45,600/yr headline figure.

The leak

$456,000
10 missed calls/mo × 40% close × $9,500 job × 12 months.
Recovered jobs per year

30% of missed calls recovered, of which ≈ 50% close → $171,000/yr in added revenue.
How we got the math
Three assumptions, each one we'd defend.
A calculator is only as useful as the assumptions behind it. Here's every number you saw above, and why we picked it.
02
30% of missed calls are recoverable
A text lands on the lead’s phone in under 60 seconds. Most of the time they reply; the ones who don’t aren’t a fit anyway. 30% is the conservative floor we’ve measured across roofing, HVAC, and plumbing shops.
03
~50% of reached leads close
Not every reply turns into a job. About half do — same as a warm inbound call answered live. The math assumes you booked the work at the same rate as before; we’re only adding the missed ones back.
Now recover it
That number is yours to keep.
Or yours to lose — depending on what you do next.
A 15-minute call. No deck. We'll review your real call volume and trade, quote setup and monthly, and tell you exactly what we'd recover in the first 90 days.
