Quick answer: A missed call costs a home service business far more than one job. Multiply your missed calls per week by the share that would have booked, your average ticket and your repeat value, and most owners find thousands of dollars a month going to competitors. Answering every call live, with a dedicated person, is usually the cheapest growth lever available.
- Use your own phone system data: count missed and abandoned calls for two normal weeks.
- Missed-call cost = missed calls x booking rate x average ticket, plus lost repeat and referral value.
- Most missed calls happen when everyone is busy: mornings, lunch, storms and heat waves.
- A virtual assistant at $12/hr can answer live during your busiest hours for less than one lost job per week.
Ask any HVAC, plumbing or roofing owner how many calls they miss and you will usually hear “not many.” Then they pull the report from their phone system. Between techs on ladders, an office manager at lunch, and the owner driving between estimates, calls go unanswered every day. Most of those callers do not leave a voicemail. They call the next company on the list.
This article gives you a simple, honest way to calculate what missed calls cost your business, using your own numbers instead of industry guesses, and then shows the practical fixes.
Step 1: Get Your Real Missed-Call Number
Pull two normal weeks of call data from your phone provider or field service software. Count:
- Missed calls: rang through with no answer
- Abandoned calls: caller hung up while on hold or in a phone tree
- Voicemails: and how long it took to call them back
Remove spam and existing customers calling about scheduled jobs. What remains is your missed opportunity count. Look at when those calls happened, too. Most owners discover a pattern: early mornings, the lunch hour, late afternoons, and any day the weather turns.
Step 2: Plug Your Numbers Into the Formula
The basic formula is:
Monthly missed-call cost = missed new-customer calls per month x booking rate x average first ticket
Here is a worked example with assumed numbers. Replace each one with your own.
| Input (example only) | Value |
|---|---|
| Missed new-customer calls per week | 10 |
| Share that would have booked if answered | 50% |
| Average first ticket | $350 |
| Lost revenue per week | 10 x 0.5 x $350 = $1,750 |
| Lost revenue per month (about 4.3 weeks) | about $7,500 |
That example does not include the biggest piece: what that customer would have been worth over time. A homeowner who books a $350 repair may later buy a maintenance plan, a water heater or a full system replacement, and refer neighbors. If you know your average customer lifetime value, use it, and the number grows quickly.
Step 3: Compare It With the Cost of Answering
Now compare the lost revenue with what it costs to answer those calls. Your options usually look like this:
| Option | What you get | Watch out for |
|---|---|---|
| Voicemail and callbacks | Free | Most new callers will not wait |
| Answering service | Someone picks up and takes a message | Usually cannot book, dispatch or sell; per-minute fees climb in busy months |
| In-house CSR | Full control, on-site | Wages, payroll taxes, benefits, desk space, turnover, and gaps during breaks and time off |
| Virtual assistant | Dedicated person who answers live, books and dispatches in your software, and follows up | Needs a clear script and onboarding in the first few weeks |
For context, the Bureau of Labor Statistics reports a 2025 median receptionist wage of $18.27 per hour before benefits and overhead. A full-time Go Hire Virtual General VA at $12/hr costs about $24,960 a year. In the example above, a VA pays for itself if it saves roughly one or two jobs a week.
Step 4: Fix the Hours When Calls Are Missed
You do not have to cover every hour of the day to fix most of the problem. Start with the windows where your data shows the most missed calls:
- 7 to 9 a.m.: homeowners call before work, and your team is loading trucks
- Lunch: the office person is away, and techs are on jobs
- 4 to 7 p.m.: people call after work, just as your office closes
- Weather events: heat waves, freezes and storms that triple call volume
A VA can work a shift built around those windows, or cover lunches and overflow while your in-house team handles the rest.
Step 5: Make Every Answered Call Count
Answering is only half the job. To turn calls into revenue, whoever answers should:
- Use a short script that captures the problem, address, urgency and how the caller found you
- Book directly into your field service software instead of promising a callback
- Offer the earliest slot first, and a backup option
- Confirm by text with the arrival window and tech name
- Log the lead source so you know which marketing works

The Bottom Line
Missed calls are invisible on your P&L, but they are real revenue walking to competitors. Measure them for two weeks, put a dollar figure on them, and compare that with the cost of answering. For most home service companies, a dedicated person answering live during busy hours is the highest-return hire they can make.

Frequently Asked Questions
How do I calculate the cost of missed calls?
Multiply missed new-customer calls per month by the share that would have booked and your average first ticket. Then consider lifetime value, since many customers would have bought again or referred others.
When do home service businesses miss the most calls?
Usually early mornings, the lunch hour, late afternoons after the office closes, and during weather events like heat waves, freezes and storms. Check your phone system data to find your own pattern.
Is an answering service enough for a home service company?
An answering service can take messages, but it usually cannot book jobs in your software, dispatch technicians or follow up on estimates. A virtual assistant does all of those, so more calls become paid work.
How much does it cost to have a virtual assistant answer calls?
Go Hire Virtual General VAs start at $12/hr. A full-time VA costs about $24,960 a year, with no payroll taxes, benefits or recruiting fees on your side.
Do I need full-day coverage to fix missed calls?
Not always. Many companies start by covering the hours with the most missed calls, such as mornings, lunches and after-hours overflow, and expand from there.
