How we calculate this
Monthly inbound calls × miss rate = missed calls. Missed calls × booking conversion rate × average job value = monthly revenue lost. Annual = monthly × 12. This is first-job revenue only — it doesn't include repeat work, referrals, or customer lifetime value, so your true exposure is higher.

Why missed calls are the biggest fixable revenue leak in home services
Industry research shows home service contractors miss 27–62% of inbound calls — often because techs are on a roof, under a sink, or in a panel when the phone rings. Roughly 85% of callers who hit voicemail never call back and instead dial a competitor. The revenue impact is not one missed tune-up — across a month of unanswered calls it routinely adds up to tens of thousands of dollars in booked work you never saw.
This calculator uses the standard industry formula: missed calls × booking conversion rate × average job value. Enter your monthly call volume and miss rate to get missed calls, apply your booking rate to get lost jobs, then multiply by your blended average job value. Adjust every input to match your shop — defaults are conservative and sourced from industry benchmarks (WhatConverts, ServiceTitan, Dexcomm).

How do I calculate the cost of missed calls?
Multiply your missed calls by your booking conversion rate and your average job value. For example: 18 missed calls × 28% conversion × $1,200 average job value = $6,048/month in lost revenue, or about $72,500 a year. This is first-job revenue only — repeat work and referrals make the true cost higher.
What is a typical miss rate for HVAC, plumbing, and electrical contractors?
Research ranges from 27% (WhatConverts HVAC study) to 62% (contractor workforce surveys). ServiceTitan data shows roughly 18% of calls go unanswered on weekdays, jumping to 41% on weekends. Use your phone system call logs for a 30-day actual miss rate rather than guessing.
What should I use for average job value?
Use your blended average across every booked job — a mix of small service calls, mid-size repairs, and larger installs or replacements — not just your routine ticket. Big-ticket installs pull the blended average up, so most shops land well above their service-call price. Check your invoicing or CRM for the last 90 days.
Does this include customer lifetime value?
No — this calculator shows first-job revenue loss only. Full lifetime value (repeat tune-ups, maintenance plans, referrals, and future replacements) is typically 3–5× the first job but varies widely by trade and retention, so your real exposure is higher than the figure shown.
Is this missed call calculator free?
Yes. Every tool on CloseCrew is free for contractors — no account required. Pair it with the Profit Margin Calculator and Job Pricing Calculator to understand both what you lose on missed calls and what each booked job should earn.
