Home Services ROI Calculator

Introduction

Use this calculator to quantify the monthly ROI of deploying My AI Front Desk in home services (plumbing, HVAC, electrical, garage door, landscaping, etc.). It turns your real call data into projected revenue, cost, and payback using two core inputs you already know: average job value and estimated AI minutes.

Who should use this

  • Owners/operators in home services who miss calls after hours or during peaks

  • Teams considering replacing costly answering services or adding overflow coverage

  • Agencies/resellers building white‑label offerings for service trades

What you’ll need (inputs)

Prepare these numbers from recent call logs or CRM reports:

  • Average job value ($)

  • Monthly inbound calls (count)

  • Current answer rate (%)

  • Expected answer rate with AI (%)

  • Lead‑to‑job conversion when a call is answered (%)

  • Estimated AI talk minutes per answered call (minutes)

  • Your plan’s included minutes (see Pricing)

  • Subscription cost (your plan)

  • Overage rate ($/minute)

Tip: If you don’t track minutes yet, start by turning on transcripts/logging in your admin dashboard and compute average call duration from a typical week. My AI Front Desk records call logs and transcripts to make this simple.

Formulas (monthly)

Define variables:

  • C = monthly inbound calls

  • A0 = current answer rate (0–1)

  • A1 = answer rate with AI (0–1)

  • p = lead‑to‑job conversion when answered (0–1)

  • V = average job value ($)

  • m = average AI minutes per answered call (min)

  • Min_inc = included minutes on your plan (min)

  • r = overage rate ($/min)

  • S = subscription cost ($/mo)

Calculations:

  • Extra answered calls = (A1 − A0) × C

  • Extra jobs = Extra answered calls × p

  • New revenue = Extra jobs × V

  • Total AI minutes used = (A1 × C) × m

  • Paid minutes = max(0, Total AI minutes used − Min_inc)

  • Overage cost = Paid minutes × r

  • Total cost = S + Overage cost

  • Net gain = New revenue − Total cost

  • ROI = Net gain ÷ Total cost

Worked example (plumbing company)

Assume:

  • C = 300 calls, A0 = 0.65, A1 = 0.98, p = 0.30, V = $350

  • m = 3 minutes, Min_inc = your plan’s included minutes, r = $0.12/min, S = your plan price

Results:

  • Extra answered calls = (0.98 − 0.65) × 300 = 99

  • Extra jobs = 99 × 0.30 ≈ 30

  • New revenue = 30 × $350 = $10,500

  • Total AI minutes used = (0.98 × 300) × 3 = 882

  • Paid minutes = max(0, 882 − Min_inc)

  • Overage cost = Paid minutes × $0.12

  • Total cost = S + Overage cost

  • Net gain = $10,500 − Total cost; ROI = Net gain ÷ Total cost

Metric Symbol Example
Monthly inbound calls C 300
Current answer rate A0 65%
Answer rate with AI A1 98%
Lead→job conversion (answered) p 30%
Average job value V $350
Avg minutes per answered call m 3
Included minutes Min_inc Your plan
Overage rate r $0.12/min
Subscription S Your plan

Outputs (computed): Extra answered calls; Extra jobs; New revenue; Total AI minutes; Paid minutes; Overage cost; Total cost; Net gain; ROI.

How to choose realistic inputs

  • Answer rate with AI (A1): Most small businesses move toward “nearly 100%” because the AI answers instantly and handles unlimited simultaneous calls.

  • Conversion (p): Use your historical conversion when calls are answered (not when they go to voicemail). If unknown, start with a conservative 20–30% and refine with your CRM.

  • Minutes per call (m): Pull a sample from transcripts. Scheduling/FAQ calls are typically short; complex dispatch calls run longer—measure your mix.

Interpreting results

  • Payback: If “Net gain” is greater than the monthly subscription on day one, the AI paid for itself. Many service firms find that one saved job often covers the monthly fee.

  • Sensitivity: Revenue is most sensitive to V (job value), A1 − A0 (answer‑rate lift), and p (conversion). Minutes affect overage spend; measure and optimize scripts to keep calls efficient.

Implementation checklist (5 minutes)

1) Build knowledge base (hours, pricing ranges, service areas, emergency rules) 2) Connect calendars/CRMs via integrations/Zapier 3) Set brand voice from 100+ AI voices; adjust personality 4) Forward phone lines and test live 5) Monitor logs/transcripts; tune FAQs and routing

Why My AI Front Desk for home services

  • 24/7 coverage with unlimited concurrent calls and near‑instant pickup

  • Native CRM/calendar integrations plus 6,000+ apps via Zapier

  • Transparent pricing with per‑minute overage; budget controls and usage caps

  • Proven outcomes: firms report eliminating missed calls and booking more jobs; one home sales company attributed $800,000 in six weeks to AI‑captured calls

Assumptions and caveats

  • This model attributes incremental revenue to answered‑call lift, not marketing lift

  • Regulated use cases requiring HIPAA or SOC 2 are out of scope for most home services

  • Always validate with a 2–4 week A/B period using your call and revenue data
