How much are missed calls costing your business?
Most small business owners massively underestimate what missed calls actually cost. Pick your industry, drag the sliders to your numbers, and see your monthly exposure in real time. Conservative math, no marketing fluff.
Calculate your missed-call cost
Calls that go unanswered, hit voicemail, or come in after hours.
What a typical converted call is worth to your business.
The percentage of answered inquiry calls that turn into paying jobs.
Service tickets average $420; replacement systems multiply this by 10-25×.
At $149/mo for the Starter plan, EMOR Voice pays for itself 33.8× over — every month — when it captures calls you currently miss.
How we calculate this
Monthly lost revenue = (missed calls/week × 4 weeks) × conversion rate × average ticket. The math is deliberately conservative — it treats every missed call as "would have converted at the typical rate" rather than accounting for higher-conversion emergency or pain-driven calls separately. Industry defaults are realistic mid-range numbers from each trade; if your shop has different volume, ticket value, or close rate, drag the sliders to your real numbers. The ROI multiplier compares to the Starter plan only — Professional and Enterprise add unlimited bookings, leads, and deeper analytics.
The reality of missed calls in small business
Typical missed-call rate at small service businesses without dedicated phone coverage. Most owners assume their rate is 5-10%.
Don't leave voicemails. They call the next listing. Voicemail-as-coverage is mostly a fiction.
Typical range across the businesses that run this calculator. Some shops reveal $100k+/year in missed revenue.
How to use this calculator effectively
The math is simple — but the inputs matter. Three minutes spent on accurate inputs gives you a defensible number you can act on; sloppy inputs give you a number to argue with.
Pick the industry preset closest to your business
Each preset pre-fills realistic mid-range defaults for that trade — typical missed-call rate, average ticket value, and conversion rate when calls are answered. Use this as your starting point, not your ending point.
Adjust missed calls per week to your real volume
If your VoIP provider gives you call analytics (RingCentral, Grasshopper, Google Voice, etc.), use the actual missed-call count. If not, count voicemails left in a typical week and multiply by 3-4 (most missed callers do not leave voicemails). Most owners discover their real missed-call rate is 2-3x higher than they assumed.
Use weighted-average ticket value, not your highest job
The right number is what your typical paying customer spends on a typical visit. If you have a wide spread (e.g. plumbers with $200 service calls AND $15,000 sewer-line replacements), pick a number that represents your most common job — not the highest. The math should be conservative on purpose.
Set conversion rate to your real close rate, not a vendor's pitch
The default values are mid-range estimates that already account for some non-buyer call volume (wrong numbers, telemarketers, casual browsers). Emergency-driven trades often convert higher (40-60%) because the caller needs you NOW. Quote-driven businesses convert lower (15-25%) because of longer sales cycles. If you know your actual close rate, use it; if not, the preset is a reasonable estimate.
Why missed-call rates and costs differ so dramatically by industry
Three structural factors decide where your business sits on the missed-call cost spectrum. Knowing which category you're in tells you what kind of solution actually fits.
Emergency-driven trades
Examples: HVAC, plumbing, electrical, locksmith, septic, garage door, tree service
Highest conversion rates (40-60%) because callers need help right now. Lowest tolerance for voicemail — they hang up and dial the next listing within seconds. After-hours and weekend calls are the highest-revenue moments.
Missed-call cost is mostly direct revenue: each missed call is a job that booked elsewhere within hours. Lifetime value compounds because emergency-relationships often become recurring service customers.
Quote-driven trades & professional services
Examples: Roofing, awning installation, general contracting, real estate, law firms, med spas
Lower immediate conversion rates (20-30%) because of multi-step sales cycles. Buyers shop multiple providers; the first one to respond wins the in-person visit, which converts at much higher rates.
Missed-call cost is potential commission/contract revenue. One missed real-estate sign call could be a $10,000 commission. One missed remodel inquiry could be a $30,000 project. Volume is lower, ticket is higher.
Recurring-care & subscription practices
Examples: Dental, optometry, veterinary, chiropractic, physical therapy, pest control, gyms
Mix of new-patient/client acquisition (high LTV) and existing-customer scheduling (high volume, low margin per call). Front desk gets buried during peak hours by routine reschedule traffic, missing the new-patient calls.
Direct revenue per missed call is moderate ($500-$2,500 first-year value), but multi-year retention compounds. A missed dental new-patient call is $400/yr × 8-15 years; a missed gym tour is $1,800/yr LTV.
High-volume scheduling businesses
Examples: Salons, barbershops, auto repair, landscapers, restaurants
Lowest per-call ticket but highest call volume (30-60+ calls/week missed during peak hours). Saturday mornings, lunch rushes, and seasonal surges are the structural leakage points. Stylist-specific or service-specific routing complicates handling.
Per-call ticket is small ($40-$150) but volume × LTV compounds fast. A salon misses 30 calls per week; even 10 of those becoming regular clients at $1,500/yr each is $15,000+ in annual recurring loss.
What the calculator shows for actual small businesses
Three owner profiles across different industries — what their inputs look like, what the calculator returns, and what they do with the number.
3-truck HVAC contractor in Florida
- •12 missed calls/week (mostly evenings + Saturday)
- •$420 average service ticket
- •30% would-have-converted close rate
Owner ran the numbers after the AC service-call rush in July. The number was high enough that he switched from voicemail-with-callback to an AI receptionist that same week. ROI math: EMOR Starter at $149/mo paid for itself the first weekend it captured one after-hours emergency that would have gone to voicemail. Net change: roughly 4-5 additional service calls/month captured = $1,800/mo new revenue at 65% margin = $1,170/mo profit improvement before counting LTV.
2-doctor dental practice in suburban Texas
- •20 missed calls/week (mostly lunch hours + after 5pm)
- •$1,500 first-year patient value
- •30% conversion to new-patient appointment
Practice manager was skeptical at first — 'we don't miss that many calls.' Pulled the actual call analytics from their VoIP provider over a 2-week sample: 41 missed calls in 14 days. The calculator confirmed the leak was real. Action: hired one part-time front-desk staffer specifically for lunch coverage + added an AI receptionist for after-hours. Recovered ~70% of the missed calls within 60 days. Long-term LTV recovery (8-15 year patient relationships) is dramatically higher than the calculator's first-year figure.
Single-stylist salon in Austin
- •18 missed calls/week (mostly Saturday morning rush)
- •$90 average service ticket
- •35% conversion to booked appointment
Owner was unsure if the cost justified any solution. Used the calculator's LTV view: 25 of those missed calls/month (out of 72 missed total) would have become regular clients at ~$1,500/yr each = $37,500 in lost first-year LTV. Action: added an AI receptionist focused on stylist-specific booking. The calculator number wasn't the highest she'd seen but the LTV math made the decision obvious.
What to do once you have your number
The calculator gives you a number. The number is only useful if it changes a decision. Three honest paths based on what you find.
The leak is small — voicemail-plus-callback may be enough
If your missed-call cost is genuinely low (very small business, low-volume professional service, or you already have strong phone coverage), the cost of any solution may exceed the revenue recovery. Stay with what you have. Re-run the calculator quarterly as your business grows.
The leak is real — an AI receptionist usually pays for itself in week one
At this exposure, even capturing 30-40% of the missed calls returns multiples of what an AI receptionist costs ($149-$249/mo). The fastest economic return is forwarding your existing business number to an AI receptionist for 7-14 days, measuring the actual call recovery, then deciding to commit. No upfront cost, low setup time.
The leak is substantial — combine AI + part-time human
At this volume, an AI receptionist alone captures most of the recoverable revenue, but specific call types (emotionally complex situations, high-value consultations, complex intake) often justify a part-time front-desk hire alongside. Most businesses in this band run AI as the always-on layer with a human handling specific call patterns the AI flags.
The leak is structural — it's a hiring decision, not a tooling one
At this scale, missed calls are likely a symptom of broader operational issues: capacity constraints, broken intake processes, or growth that has outpaced staffing. An AI receptionist will help, but the real fix is reviewing the entire customer-acquisition pipeline. Consider an SEO/operations audit alongside the receptionist decision.
EMOR Voice answers every call you currently miss.
EMOR Voice is an AI receptionist that answers your business phone 24/7 in under one second, books appointments in real time, captures leads with full context, and sends SMS confirmations to callers. For most small businesses, it captures 80-95% of calls that currently go to voicemail — flat $149/month for the Starter plan.
Frequently asked questions about the calculator
How do I figure out how many calls I actually miss?+
If your phone provider gives you call analytics, look at total inbound calls vs. total answered calls. The difference is missed. If you don't have that data, a useful estimate: count voicemails left in a week (most missed calls don't leave voicemail), then multiply by 3-4. For most small businesses, the realistic missed-call rate is 20-40% of total inbound — meaningfully more than owners expect.
Why does conversion rate matter in the math?+
Not every answered call becomes a paying job. A typical conversion rate (the percentage of answered inquiry calls that actually convert to revenue) is 25-40% for most service businesses. Emergency-driven trades (locksmiths, plumbing, HVAC after-hours) convert higher (40-60%) because the caller needs you NOW. Quote-driven businesses (general contractors, awning installers) convert lower (15-25%) because there's a longer sales cycle.
Doesn't this overestimate the loss? Some missed calls are just wrong numbers.+
The conversion rate input handles this. If 30% of your missed calls are wrong numbers, telemarketers, or non-buyers, your effective conversion rate drops accordingly. The slider lets you adjust to match your real call quality. The default values are mid-range estimates that account for some non-buyer call volume.
My ticket value varies a lot. Should I use my average or my median?+
Use your weighted average — what your typical paying customer spends on a typical visit/job. If you have a wide spread (e.g. plumbers with $200 service calls and $15,000 sewer-line replacements), pick a number that represents your most common job type, not the highest. The math will be conservative.
Does this account for repeat customers and lifetime value?+
No — and that's intentionally conservative. The calculator only counts the immediate revenue from one converted call. For most service businesses, captured customers come back (recurring service, return business, referrals), so the actual long-term loss from missed calls is significantly higher than what the calculator shows. We chose to underestimate rather than overstate.
How does EMOR Voice actually recover this revenue?+
EMOR Voice answers every business call in under one second, books appointments in real time, captures lead context, and sends SMS confirmations — 24/7, in English and Spanish, without a human dispatcher. For most small businesses, the system captures 80-95% of calls that previously went to voicemail. The remaining 5-20% are calls EMOR routes to a human callback per the business owner's rules.
How accurate is the calculator? What's the methodology?+
The math is intentionally simple and defensible: monthly lost revenue = (missed calls per week × 4 weeks) × conversion rate × average ticket. There are no hidden multipliers, no opaque "industry constants." Industry default values come from real data on each trade's typical volume, ticket value, and close rate, but the sliders let owners adjust to their actual numbers in 30 seconds.
