§Worked Examples

Artisan Ava - Accelerate plan

Monthly fee: $2,500
Meetings expected: 15/month

$167/meeting

Beats human SDR at $480/meeting by 65%

11x Alice - base tier

Monthly fee: $5,000
Meetings expected: 20/month

$250/meeting

Beats human SDR at $480/meeting by 48%

Retell AI voice agent (inbound qual.)

Rate: $0.07/min
2-min avg call, 500 calls/mo
10% conversion to meeting

$7/meeting (platform) + LLM

Voice AI for inbound is very cheap; all-in ~$15-30/meeting with LLM

Human SDR (fully loaded)

$65k OTE + 30% benefits + $2k tooling
15 meetings/month
$86,500/year = $7,208/month

$480/meeting

Baseline to beat. AI SDR wins at 10+ meetings/month consistently.

§Methodology

What is counted: Platform monthly fee (or all-in per-minute rate x expected call volume for voice AI). Divided by meetings booked per month.

What is not counted: Management overhead to configure and monitor the AI SDR; internal IT time for CRM integration; occasional human review of AI-flagged anomalies. These typically add $500-$1,500/month equivalent for AI SDR; less for voice AI inbound.

Human SDR calculation: OTE salary + 30% benefits (healthcare, payroll tax, equity) + $2,000/year tooling (Outreach/Salesloft seat, ZoomInfo seat, LinkedIn Sales Navigator) = fully-loaded annual cost. Divided by 12 for monthly. 15 meetings/month is a typical productive SDR output after ramp; first 3 months excluded.

Voice AI meeting conversion: Outbound appointment confirmation typically converts at 15-30% (known contact, prior relationship). Outbound cold call AI would need prior express consent under the TCPA (see legal guide). Inbound qualification converts at 20-50% of qualified leads reached.

AI SDR reality check: First 60-90 days of deployment typically yield below-target meetings as the sequence is tuned to the specific ICP, messaging is refined, and data quality is validated. Evaluate ROI only after 90 days of production deployment.

§The Legal Caveat on Voice AI ROI

Voice AI outbound cold calling looks cheapest on paper - and carries the most legal risk

A Retell-built outbound cold-call agent at $0.07/min x 2-min avg x 5,000 calls/month x 4% meeting conversion = 200 meetings at $700 platform cost + ~$200 LLM = $4.50/meeting. That is the best ROI number on the chart. It also assumes you have prior express consent for every number you dial - a legal requirement under FCC Ruling 24-17 (February 2024). Without that consent infrastructure, you are looking at TCPA violations at scale.

§FAQ

What is cost per meeting booked?

Cost per meeting booked = total monthly spend on the sales outreach channel divided by the number of qualified meetings booked that month. It is the primary ROI metric for AI SDR and voice AI deployments because it is directly comparable to the cost of a human SDR producing the same meetings. A lower cost per meeting with equivalent quality is a better deployment.

How much does an AI SDR cost per meeting?

At current pricing: Artisan Ava ($2,500/month) at 15 meetings = $167/meeting. 11x Alice ($5,000/month) at 20 meetings = $250/meeting. A human SDR ($7,208/month fully loaded) at 15 meetings = $480/meeting. AI SDR beats the human SDR at 10+ meetings/month consistently. Performance in the first 90 days is typically lower than steady state.

What is a realistic meetings-per-month target for an AI SDR?

Industry benchmarks and vendor case studies (which are self-selected) suggest 10-30 meetings per month for a well-configured AI SDR with a clear ICP in a responsive market segment. Realistic steady-state targets after 90-day tuning: 10-20 meetings/month for most deployments. High-volume outreach into large addressable markets with proven messaging can reach 30+. Teams in niche verticals or with complex products typically see 5-15.

Should I include management time in the ROI calculation?

Yes. Managing an AI SDR requires approximately 2-4 hours/week from a RevOps or sales ops person to review performance, tune messaging, escalate anomalies, and maintain CRM integrations. At a fully-loaded cost of $150/hour for a RevOps manager, that is $1,200-$2,400/month in management overhead. This is still materially cheaper than the overhead of managing a human SDR, but it is not zero.
