What This Calculator Shows You
Before any smart business owner writes a check, they want to know the return. This free AI ROI Calculator is built specifically for home service contractors evaluating an AI voice agent — showing you exactly how much revenue you can recover from missed calls, what that's worth annually, and how many months it takes to pay back the investment. No fluff, no estimates — just your numbers.
The case for AI phone answering is built on one simple premise: missed calls cost more than a solution. Most contractors who run this calculation discover they're losing 10–30x the cost of an AI agent every single month. The question isn't whether the math works — it's whether you believe it enough to act on it.
How to Use This Calculator
Enter your monthly missed calls
Pull from your call log. If you don't track this, estimate: how many calls come in after 5pm? On weekends? During busy service days when your team is maxed out?
Enter your average job value
Blended average across all job types. Service calls, repairs, replacements — weight it toward your most common job mix.
Enter your close rate
The percentage of qualified inbound leads you convert to booked jobs. Be realistic — 35–50% is typical for most contractors.
Enter the AI agent monthly cost
AI Home Services plans start at $149/month. Use your actual quoted price or the $149 baseline.
Review your payback period and annual ROI
The calculator shows months to break even and total annual return. Most contractors see break-even in the first week of month one.

The Complete Guide to AI ROI for Contractors
Every technology investment demands a return on investment calculation. For AI voice agents in the home services industry, that ROI calculation is unusually clear and unusually favorable — because the cost of inaction (missed calls = lost revenue) is quantifiable and immediate.
The baseline problem: what are you losing now?
Before you can calculate ROI, you need to establish your baseline loss. How many calls per month go unanswered? For a typical 3–5 truck operation, this ranges from 20 to 80 calls per month depending on team size, hours of operation, and seasonality. Every unanswered call has an expected value: your close rate × your average job value.
At a 40% close rate and $500 average job value, each missed call is worth $200 in expected revenue. Miss 40 calls per month, and you're leaking $8,000 every month — silently, without a bad review or customer complaint you can see.
The AI agent solution
An AI voice agent answers every call — first ring, every time, 24/7. It introduces itself, qualifies the caller (what service do you need? Is this an emergency? What's your address?), and either books an appointment directly into your dispatch calendar or escalates to a human for complex situations. No hold times. No voicemail. No lost leads.
At $149/month, you're spending $1,788 per year. If the agent recovers even 10 of those 40 monthly missed calls — a 25% recovery rate on the conservative end — that's 10 × $200 expected value = $2,000 per month in recovered revenue. Your ROI is 1,243% annually.
Beyond direct revenue recovery
The revenue recovery calculation is the easy part. The full ROI picture includes:
- Brand perception: Customers who reach a live (or AI) agent immediately form a better first impression than those who hit voicemail.
- Reviews: Fewer "I called and no one answered" reviews — one of the most common complaints in contractor reviews.
- CSR efficiency: When AI handles routine qualification and scheduling, human staff can focus on complex customer interactions and upselling.
- Owner time: Every call you personally answer costs you time that should be spent on growth activities.
The payback period is days, not months
At $149/month, you need to recover one $150 job to break even. In most markets, that happens in the first 24–48 hours of deployment. The ROI question for AI answering isn't "does it pay for itself?" — it's "why didn't I do this sooner?"
Why This Matters for Your Business
The ROI on AI phone answering isn't theoretical — it's based on the revenue you're already losing every month. This calculator turns your specific numbers into a business case you can act on. If the math works, the next step is booking a demo to see the technology in action.
Pro Tips from Top Contractors
Include after-hours calls in your missed call count — these are highest-intent leads and most likely to convert quickly.
Factor in customer lifetime value, not just first-job value. A recovered HVAC customer may spend $800/year on maintenance agreements.
Run the calculator with conservative inputs. Even at 50% recovery and a 35% close rate, most contractors see 5–10x ROI.
Consider the opportunity cost of your time answering and qualifying calls — that time has value too.
