Missed Call Revenue Loss Calculator

How the calculator works

The math is deliberately simple, so you can check it by hand:

1. Missed calls per month = calls per week × 52 ÷ 12 × the share of calls that go unanswered.
2. Callers lost = missed calls × the share of those callers who never reach you (they don’t call back, or you call back too late).
3. Jobs lost = callers lost × your close rate.
4. Lost revenue = jobs lost × your average job value, per month and × 12 per year.

The fix section divides the fix’s monthly cost by your average job value to show how many recovered jobs it takes to break even, then applies your “wins back” percentage to estimate the net result.

We don’t pre-fill industry “averages” because the honest answer varies a lot by trade, season, and how your phones are staffed. The defaults, including the trade presets, are placeholders. Your own call log is a far better source than any survey. For trade-specific scenarios and advice, open the versions for plumbers, HVAC companies, dental offices, or pest control companies.

Where to find your real numbers

• Calls and missed calls: most business phone systems, VoIP apps, and call-tracking tools show answered vs. missed calls. Pull the last four weeks so one busy or quiet week doesn’t skew it, and include after-hours calls.
• Callers who never get through: compare missed numbers with numbers you later spoke to or booked. Anyone missed who never appears again is a likely loss.
• Close rate: jobs booked ÷ answered calls over the same period. If you only want to count new-customer calls, lower the call volume instead.
• Average job value: your average invoice from your accounting or field-service software. Leave out your biggest one-off jobs.

How to reduce missed calls (and win back the ones you miss)

Once you know roughly what missed calls cost, the fix usually comes from one or more of these, cheapest first:

1. Text back every missed call automatically

A missed call text back sends the caller a short text within seconds, so the conversation continues by SMS instead of dying in voicemail. It’s the cheapest fix and works around the clock. Trade-specific wording helps: see our text-back scripts for plumbers and for auto repair shops. Our free missed call text message generator writes one for your trade and counts its SMS segments. In the US you’ll need A2P 10DLC registration before you text customers from a local number.

2. Script your after-hours calls

Many missed calls come in at night and on weekends. A written after-hours script tells whoever (or whatever) answers which calls are emergencies and which can wait. Start from our HVAC, plumbing, or electrician after-hours answering scripts.

3. Cover overflow with an answering service or AI receptionist

If callers need a live conversation, route unanswered calls to a live answering service or an AI receptionist. Published prices vary widely, from a few cents a minute for AI to several dollars a minute for live receptionists. Our answering service cost guide compares published prices from nine providers, and our AI receptionist vs. answering service vs. voicemail comparison covers the trade-offs beyond price.

4. Put it on one system

HighLevel bundles a business phone line, missed call text back, a CRM, calendars, and optional Voice AI in one platform from $97/month plus usage. Our GoHighLevel pricing guide breaks down the real monthly bill, including texting and phone usage.
