What missed calls actually cost your business
Every unanswered ring is a customer deciding between leaving a voicemail and calling the next name on the list. Most owners have never put a dollar number on that. This chapter does it in 30 seconds — with your numbers, not a vendor's slide — then compares the three fixes like-for-like.

1. Inbound calls per month. Don't guess. Your carrier portal or phone bill lists total inbound calls; if you use Google Business Profile, the Calls tab shows calls placed from your listing. Take last month's number.
2. Percent missed. Count voicemails + abandoned rings against total inbound. Include lunch hours, jobsite hours, and everything after close — after-hours is usually the single biggest block. Industry studies put small-business miss rates at 27–62%; owners who measure are usually surprised which end they're on.
3. Booking rate and job value. Booking rate = of answered calls, how many become customers (see the FAQ below for honest starting points). Job value = your average ticket — or lifetime value if repeat business is your model (a dental patient is worth far more than one cleaning).
A worked example
A plumber missing 5 calls a week (≈21.7 a month), average job $400, booking rate 35%:
21.7 missed calls × 35% × $400 = $3,031/month — about $36,000 a year leaking through the phone. That's the formula the calculator runs, printed so you can check it against your own math.
The three fixes, compared honestly
An option pays for itself when its monthly cost is less than calls recovered × booking rate × job value. With the example numbers, every recovered call is worth ~$140 — so even a $500/month service breaks even at four recovered calls a month.
| Option | Typical cost (July 2026) | Where it wins | Where it breaks |
|---|---|---|---|
| Live answering service | $150–$400/mo (per-minute plans) | Real human empathy; complex or upset callers | Per-minute fees balloon at volume; agents read from your script but can't book into your calendar or answer real pricing questions |
| AI receptionist | $20–$99/mo self-serve · $497+/mo custom-built | 24/7 including the after-hours block where most calls die; books appointments; flat cost | Self-serve tiers are generic phone trees with AI on top; healthcare/legal need compliance work (BAAs, intake rules) that cheap tiers don't offer |
| Front-desk hire (part-time) | $1,600–$3,400/mo at $15–20/hr | Everything a human does beyond the phone — front office, walk-ins, judgment | Covers ~40 of the week's 168 hours; sick days, turnover, and training are on you |
Where DIY works: if your miss rate is mostly business-hours overflow, tightening phone habits and a $30 self-serve AI tier may genuinely be enough — try that first.
Where DIY breaks: after-hours coverage that can actually book (not just take messages), Spanish-speaking callers, and healthcare or legal intake where a wrong answer has compliance consequences. That's the custom tier of this market — including what we build — and you should make any vendor prove those three things in a live demo before paying for them.

Questions owners actually ask
Where do the cost ranges for the three options come from?
Published prices as of July 2026: live answering services typically run $150–$400/month at small-business call volumes (per-minute plans), AI receptionists range from $20–$99/month self-serve to $497+/month custom-built, and a part-time front-desk hire costs $1,600–$3,400/month at $15–$20/hour. Always verify current pricing with the vendor — these move.
What's a booking rate and what should I enter?
Of the calls you DO answer, the percentage that become paying customers. New-customer inquiry calls convert high — dental practices often see 40–50%, home services 30–45%, law firms 20–35%. If you don't track it, start at 30–35% and refine after a week of tallying.
What if the calculator says missed calls barely cost me anything?
Then do nothing — that's a legitimate result. If you miss two calls a month, no answering product pays for itself. This playbook's rule is that the math decides, not the vendor.
