# Missed Call Revenue Calculator

Missed call revenue is the money a business loses when potential customers call and nobody answers. To estimate it, multiply weekly calls by the share you miss, by your booking rate, by your average ticket, then by 52. A shop missing 25% of 60 weekly calls loses about $140,400 a year.

## Key takeaways

- Lost revenue per year = calls per week × miss rate × booking rate × average ticket × 52.
- Use only calls from potential customers. Leave out vendors, spam and existing-job updates.
- Your phone carrier's call log shows missed and abandoned calls; most owners underestimate them.
- Missed calls cluster in busy season and after hours, exactly when demand is highest.

## How to calculate missed call revenue

**Formula**

```
Lost revenue per year = C × M × B × T × 52
```

Where:
- C = calls from potential customers per week
- M = share of those calls you miss (missed ÷ total)
- B = booking rate: share of answered calls that become a booked job
- T = average ticket: average revenue per job

1. **Count your customer calls.** Pull one normal week from your phone carrier or call-tracking log. Count calls from new and existing customers who want work done.
2. **Find your miss rate.** Divide calls that rang out, went to voicemail or hung up on hold by total customer calls.
3. **Find your booking rate.** Divide jobs booked from phone calls by calls you answered. Your [booking rate](https://www.brix.so/learn/booking-rate) is usually lower in slow season, when callers shop around.
4. **Multiply it out.** Missed calls × booking rate gives jobs lost per week. Multiply by your [average ticket](https://www.brix.so/learn/average-ticket), then by 52 for the year.

> **Worked example**
>
> An HVAC company gets 60 customer calls a week and misses 25% of them: 15 missed calls.
>
> It books 40% of the calls it answers, so those missed calls were worth 6 jobs a week.
>
> At a $450 average ticket, that is $2,700 a week, $11,700 a month, or **$140,400 a year**.

## Why the real cost is usually higher

- **Lifetime value.** A first service call often turns into a maintenance plan, a replacement or a referral. The [customer lifetime value](https://www.brix.so/learn/customer-lifetime-value) of a lost caller is usually several tickets, not one.
- **Emergency calls skew high.** No-heat, burst-pipe and storm-damage calls carry bigger tickets and are the callers least willing to leave a voicemail.
- **Marketing spend is wasted.** If a call came from an ad or Local Services Ads, you paid for the lead whether or not you answered. See [cost per lead](https://www.brix.so/learn/cost-per-lead).
- **Missed calls are not random.** They pile up when crews are busiest, so this average understates your peak-season losses.

## How miss rates differ by trade

**Where missed calls come from, by trade**

| Trade | When calls get missed | Why it hurts |
| --- | --- | --- |
| HVAC | Heat waves and cold snaps; techs on roofs and in attics | Emergency no-heat and no-cool calls have the highest tickets of the year |
| Plumbing | Nights and weekends; owner under a sink | Burst pipes and backups call the next plumber within minutes |
| Roofing | Right after storms, when call volume spikes | Storm-damage leads choose whoever inspects first |
| Electrical | During jobs, when hands are busy | Panel upgrades and EV charger installs are high-ticket bids |
| Landscaping and lawn care | Spring rush; crews out on routes all day | Season-long contracts get decided in a few weeks |
| Pest control | Summer peak; techs on routes | One-time calls often convert to recurring service plans |

_These are common patterns, not measured miss rates. Use your own call log for the calculator._

## How to stop losing jobs to missed calls

1. **Measure it first.** Check your call log weekly so you know your real miss rate.
2. **Text back immediately.** A text within a minute of a missed call keeps many callers from dialing the next company. See [missed-call text back](https://www.brix.so/features/missed-call-text-back).
3. **Cover after hours.** An [answering service](https://www.brix.so/learn/answering-service) or [AI receptionist](https://www.brix.so/features/ai-receptionist) can answer nights, weekends and overflow.
4. **Follow up on every lead.** Callers who didn't book should get a follow-up the same day. See [speed to lead](https://www.brix.so/learn/speed-to-lead).

## Frequently asked questions

### How much do missed calls cost a small business?

It depends on call volume, booking rate and ticket size. A trades business that gets 60 customer calls a week, misses 25% of them, books 40% of answered calls and averages $450 per job loses about $140,400 a year. Enter your own numbers in the calculator above.

### How do I find out how many calls I miss?

Your phone carrier or VoIP provider keeps a call log with missed, unanswered and abandoned calls. Pull one typical week, remove spam and vendor calls, and divide missed customer calls by total customer calls.

### What is a good booking rate for phone calls?

It varies by trade, season and lead source, so the most useful benchmark is your own number over time. Calculate it by dividing jobs booked from calls by calls answered, and track it monthly.

### Does a voicemail count as a missed call?

Yes. Many callers hang up rather than leave a voicemail, and those who do leave one often call another company while they wait. Treat any call that wasn't answered live as missed.

### Is an AI receptionist worth it for a contractor?

Compare what you lose to missed calls each month with what the service costs. If the calculator shows thousands of dollars a month in lost jobs, answering those calls usually pays for itself quickly. The right choice also depends on how complex your booking questions are.

### Should I include existing customers in the call count?

Include existing customers calling for new work, because a missed call can lose that job too. Leave out calls that are only status updates on jobs already booked.
