Missed calls and no-shows cost calculator

Type in your own numbers to estimate what missed calls and no-shows cost each month and each year, and how many recovered jobs would pay for answering every call. The math runs in your browser; nothing is sent anywhere. It is an estimate, not a promise.

For illustration only. Your results depend on your market, prices and how many callers would have booked. Plan prices in USD as of October 2026; setup fees and usage above the plan allowance are not included in the break-even line.

How the estimate works

The calculator uses four steps, all from the numbers you enter:

  1. Lost bookings from missed calls = missed calls per week × 4.33 × share that are new customers × share who would have booked.
  2. Revenue from those bookings = lost bookings × average job value.
  3. No-show revenue = no-shows per week × 4.33 × average appointment value.
  4. Gross profit at risk = total revenue at risk × gross margin.

The break-even line divides the monthly AI phone answering price by your gross profit per job. It tells you how many recovered jobs a month would pay for answering every call.

Where to get the inputs

  • Missed calls: your phone system or carrier call log for the last four weeks.
  • New-customer share: compare the missed numbers with your customer list.
  • Booking share: of the new callers you did reach last month, how many booked?
  • No-shows: your booking tool's report, or your calendar for the last four weeks.

What usually fixes each number

Missed calls are fixed by answering them: a person, an AI receptionist, or a text back when the call is missed. No-shows drop with confirmations, reminders and easy rescheduling. Automation then connects those steps to your CRM so nothing is retyped. See automation for service businesses for how we connect leads, bookings and follow-up, or all prices.

Calculator questions

How do I find out how many calls I miss?

Look at the call log in your phone system or carrier account for the last four weeks and count calls marked missed, unanswered or sent to voicemail. Count each number once per day so repeat attempts by the same caller do not inflate the total.

What share of missed calls are new customers?

It depends on your business. Check the missed numbers against your customer list: numbers you do not recognize are usually new inquiries. Use your own count rather than an industry average.

Is this calculator accurate?

It is an estimate built from the numbers you type in. It shows the order of magnitude so you can decide whether fixing missed calls and no-shows is worth a closer look. It is not a forecast and does not promise any result.

What does it cost to fix missed calls?

AI phone answering is from $299/month (about 300 minutes) plus setup from $900, and the follow-up pack with missed-call text-back and reminders is from $99/month plus setup from $500 (USD, October 2026). See all prices.

Does the calculator store my numbers?

No. The math runs in your browser and nothing you type is sent anywhere.
