ROI Calculator: Is an Answering Service Worth It?

Short answer: if you miss more than 3 calls a month, almost certainly yes.

But "almost certainly" isn't good enough when you're spending money. You want to know your numbers. Not some generic stat from a blog post. Your calls. Your average job size. Your actual costs.

That's what this page is for. Below is a simple worksheet you can fill out in 5 minutes. No spreadsheet needed. Grab a pen, pull up your call log, and let's find out exactly what missed calls cost you — and whether an answering service earns back more than it costs.

The 5-Minute ROI Worksheet

Here's the math. Four numbers. One answer.

Step 1: How many calls do you miss each month?

Check your phone. Most phones track missed calls. If you don't know the exact number, start here: home service contractors miss 60-80% of incoming calls. If you get 40 calls a month and you're on a job site most of the day, you're probably missing 25-30 of them.

Your number: ______ missed calls/month

Step 2: How many of those callers would have booked?

Not every missed call is a paying customer. Some are spam. Some are tire-kickers. But research shows about 1 in 4 inbound calls to a home service business turn into a booked job. So multiply your missed calls by 0.25.

Your number: ______ lost jobs/month

Step 3: What's your average job worth?

Think about your typical ticket. A drain cleaning might be $250. A full HVAC install might be $8,000. An average plumbing call might be $350. Use whatever fits your business.

Your number: $______ average job value

Step 4: Multiply.

Lost jobs × average job value = revenue you're losing every month.

Example: 25 missed calls × 0.25 = 6 lost jobs. 6 × $350 = $2,100/month walking out the door.

Now compare that to what an answering service costs. If the answer is $59/month, the math is obvious.

Let's Run Three Real Scenarios

Numbers hit different when they're specific. Here are three home service businesses running the same worksheet.

Scenario 1: Solo Plumber

  • Gets 35 calls/month
  • Misses 22 (on jobs all day)
  • 25% would book = 5.5 lost jobs
  • Average job: $400
  • Monthly loss: $2,200
  • Answering service cost: $59/month
  • ROI: 3,627%

One captured emergency call — a burst pipe on a Saturday night — pays for months of service.

Scenario 2: Two-Person Electrical Crew

  • Gets 50 calls/month
  • Misses 30 (both techs on jobs, no office staff)
  • 25% would book = 7.5 lost jobs
  • Average job: $600
  • Monthly loss: $4,500
  • Answering service cost: $59/month
  • ROI: 7,527%

Even if only half those lost jobs actually book, that's still $2,250/month recovered from a $59 investment.

Scenario 3: Cleaning Company (5 employees)

  • Gets 60 calls/month
  • Misses 15 (office manager handles most, but not evenings or weekends)
  • 25% would book = 3.75 lost jobs
  • Average recurring contract: $200/month
  • Monthly loss: $750 (first month alone)
  • But cleaning clients stick around. Average retention: 8 months.
  • Real loss: $6,000 in lifetime value
  • Answering service cost: $59/month
  • ROI: 1,171% (on first month alone)

Cleaning companies feel this one hard. Every missed call isn't just one cleaning. It's 8 months of recurring revenue that went to the company who picked up the phone.

The Number Most People Forget

Here's where the real cost hides: 80% of callers who hit voicemail won't leave a message. They call the next business on the list.

So when you check your voicemail and see zero messages, that doesn't mean nobody called. It means the people who called already hired someone else.

Your missed call log is only part of the picture. Your actual lost calls are higher than you think, because some ring once and hang up. Some go straight to voicemail and bail.

If you're relying on voicemail to catch overflow calls, you're catching about 20% of what comes in. The other 80% is gone.

What You're Really Comparing

When you're deciding if an answering service is worth it, here's the honest comparison:

OptionMonthly CostCalls AnsweredAvailable
You answer everything yourself$0 (but you can't work)~40%Business hours only
Hire a receptionist$3,000-$4,000/month~90%Business hours only
Traditional answering service$200-$500/month~95%24/7
AI answering service$59-$259/month~99%24/7
Voicemail$0~20% catch rateAlways on, rarely works

The question isn't "can I afford an answering service?" It's "can I afford to keep missing calls?"

A full-time receptionist costs $36,000-$48,000/year. That's a real person sitting in an office during business hours only. They don't answer at 9 PM when someone's basement is flooding.

An AI receptionist costs $708-$3,108/year. It answers every call, every time, day or night. Here's how they work if you're curious.

How Do You Calculate ROI on an Answering Service?

The formula is simple:

ROI = (Revenue Recovered - Service Cost) ÷ Service Cost × 100

Using the solo plumber example above:

  • Revenue recovered: $2,200/month
  • Service cost: $59/month
  • ROI = ($2,200 - $59) ÷ $59 × 100 = 3,627%

That means for every $1 spent, you get back $36.27. Most investments beg for 10% returns. This one delivers 3,627%.

Even if you cut the numbers in half — say you only recover 3 jobs instead of 5 — that's still $1,200/month from a $59 investment. An ROI of 1,932%.

The math stays good even with conservative guesses.

Is an Answering Service Worth It for a Small Business?

For home service businesses, the answer is almost always yes. Here's why.

Your business runs on phone calls. A roofer doesn't get leads through a web form. A plumber doesn't get emergency calls by email. When a pipe bursts at 10 PM, the customer calls. If nobody answers, they call the next plumber.

The value of each call is high. You're not selling $5 widgets. A single plumbing job is $250-$800. A single HVAC install is $3,000-$10,000. One call can pay for a year of answering service.

You can't answer while you work. You're on a roof. Under a sink. Running wire through an attic. Your hands are full. Your phone is in your truck. That's the whole problem — and an answering service exists to solve it.

The only businesses where it might not make sense:

  • You already have a dedicated receptionist who answers every call
  • You get fewer than 10 calls a month total
  • Your average job value is under $50

For everyone else — and that's most home service businesses — the return is clear.

What About the Hidden Costs?

Fair question. Some traditional answering services bury costs in the fine print. Watch for:

  • Per-minute billing that adds up fast when callers have questions
  • Setup fees of $50-$200
  • Holiday surcharges (when you need coverage most)
  • Long-term contracts with early termination fees
  • Overage rates that double or triple your base price

Before you sign anything, read the full breakdown in our guide to answering service contracts.

AI answering services tend to be simpler. Cira, for example, charges per conversation — not per minute. $59/month gets you 200 conversations. No setup fees. No contracts. Cancel anytime.

How Fast Does an Answering Service Pay for Itself?

For most home service businesses, within the first week.

Here's the math. Say your answering service costs $59/month. Your average job is $350. The service needs to capture exactly one job to cover the entire month's cost. At $59/month, one booked job covers the entire month with money to spare.

Compare that to the time it takes to set up. Most AI receptionists are live in under 10 minutes. You could be answering calls before lunch and have the cost paid back by the end of the week.

Traditional answering services take longer — sometimes 1-2 weeks for setup and training. But even then, payback happens in the first billing cycle for most businesses.

The Break-Even Test

If the ROI worksheet feels like too much math, here's the quick version.

Answer one question: How many jobs would the answering service need to capture per month to cover its cost?

Service CostAverage Job = $200Average Job = $500Average Job = $1,000
$59/month1 job (done)1 job (done)1 job (done)
$159/month1 job (done)1 job (done)1 job (done)
$259/month2 jobs1 job (done)1 job (done)
$500/month (traditional)3 jobs1 job (done)1 job (done)

At every price point, the break-even is 1-3 jobs per month. If an answering service can't capture that from the calls you're currently missing, something else is broken.

What About AI vs. Live Answering Services?

Both answer your phone 24/7. But the cost structure is very different.

Live answering services hire real people. That means $200-$500/month minimum, with per-minute charges on top. Operators follow scripts. Quality varies by shift. They cover basics — take a name, number, and message.

AI answering services use voice AI. That means $59-$259/month for most small businesses. No per-minute fees. The AI answers questions about your business, sends your booking link via text, and captures lead details. It sounds natural — not like a robot menu.

The ROI gap is big. A live service at $300/month needs to recover $300 to break even. An AI service at $59/month needs to recover $59. Same number of calls answered. Same jobs captured. Very different cost.

Frequently Asked Questions

How do you calculate ROI on an answering service?

Subtract the monthly cost from the revenue you recover from missed calls. Divide by the cost. Multiply by 100. If you pay $59/month and recover $1,750 in jobs, your ROI is 2,866%.

Is an answering service worth it for a small business?

For most home service businesses, yes. If you miss even 5 calls a month and your average job is $350, that's $1,750 walking out the door. A $59/month answering service pays for itself with one booked job.

How much does an answering service cost per month?

Traditional live services cost $200-$500/month with per-minute billing on top. AI services like Cira start at $59/month for 200 conversations, with per-conversation pricing instead of per-minute.

What is a good ROI for an answering service?

Most home service businesses see 500-3,000% ROI. The exact number depends on your average job value and how many calls you miss. Even 200% means $3 back for every $1 spent.

How many missed calls does a typical home service business get?

Research shows contractors miss 60-80% of calls. If you get 40 calls a month, that's 24-32 going unanswered. At $350 per job, even converting a few of those adds up fast.

Is an AI receptionist cheaper than a live answering service?

Yes. Live services charge $200-$500/month plus per-minute fees. AI receptionists start at $59/month with flat pricing. Both answer 24/7. AI costs 70-85% less.

Can an answering service actually book jobs for me?

AI receptionists like Cira answer caller questions, send your booking link by text, and capture lead details. Some forward urgent calls to you live. The caller gets help right away instead of hitting voicemail.

How fast does an answering service pay for itself?

Most home service businesses recover the cost in the first week. If your average job is $350 and the service costs $59/month, one booked job covers the entire month.
