15 AI Voice Agent ROI Statistics (2026)

Cost Comparison
Retell lists this pay-as-you-go voice-agent range, checked October 5, 2026. It is per minute, not per call; selected models, telephony, add-ons and duration determine the bill. Some listed model configurations cost more than this headline range.
Derived from Forrester's June 2025 PolyAI-commissioned composite assumptions: five minutes per live-agent call at $30 per hour. Labor-only illustration, not an observed all-in industry average; excludes overhead beyond the modeled hourly labor input.
Forrester Consulting PolyAI TEI, June 2025, labor model A4/A6
AWS reports DoorDash operational savings from its earlier Amazon Connect and Lex self-service IVR, alongside 49% fewer agent transfers. This predates the case's generative-AI upgrade; not a measured 70-95% per-call reduction or SchedulingKit result.
AWS original DoorDash customer case study, checked October 2026
Global contact-center agent labor-cost reduction forecast for 2026 in Gartner's August 31, 2022 announcement. Covers conversational AI across voice and digital channels; historical projection, not verified realized savings or a voice-only estimate.
AWS illustrates a three-minute self-service call in US-WEST-2: Connect usage, one DID number-day, telephony, AI-agent usage and Lex speech requests. Excludes taxes, fees and surcharges. This published component-pricing example is not a universal enterprise call cost or a quote for every current AWS plan.
ROI & Payback
Three-year risk-adjusted ROI modeled for a composite enterprise in Forrester's June 2025 PolyAI-commissioned study, based on four customer interviews; not a universal voice-AI return or audited SMB average.
Forrester Consulting TEI of PolyAI, commissioned study, June 2025
Payback modeled for the composite enterprise in Forrester's June 2025 PolyAI-commissioned study; not typical payback for all voice-AI deployments. The composite has four million calls annually and 200 agents.
Forrester Consulting TEI of PolyAI, commissioned study, June 2025
PolyAI reports 3,000 reservations associated with $600,000 revenue at one Golden Nugget hotel in one month. Gross booking revenue, not incremental profit, avoided loss or an SMB average. The undated case does not provide a counterfactual or specify the measurement month.
Approximate unanswered-call share in a 30-day vendor study of 85 small businesses across 58 industries, published January 2016; includes voicemail and no response, not a current industry-specific rate.
Three-year risk-adjusted net present value for the enterprise composite in Forrester's June 2025 PolyAI-commissioned study. Discounted benefits minus discounted costs; not annual cash savings or a typical SMB return.
Forrester Consulting PolyAI TEI, June 2025 financial summary
Performance & Adoption
AWS reports DoorDash's generative-AI self-service solution fielding hundreds of thousands of Dasher support calls daily after its early-2024 test and rollout. A vendor customer case, not a Fortune 500 adoption survey; it does not say every call is fully resolved without an agent.
2007 study: 21-fold qualification-odds difference, calls at five versus thirty minutes; six companies. Not job-win probability.
Oldroyd/InsideSales Lead Response Management, 2007, pp. 20-27
Global conversational AI market projected from $17.97 billion in 2026 to $82.46 billion in 2034, at 21% CAGR. Includes chatbots and virtual assistants; not a voice-only market or realized growth.
Fortune Business Insights conversational AI forecast, September 2026
AWS reports increased first-contact resolution for DoorDash's earlier Connect and Lex IVR. The article does not specify whether this is relative growth or percentage points, or provide an absolute resolution rate; it is not the later generative-AI upgrade's result.
AWS original DoorDash customer case study, checked October 2026
PolyAI's Golden Nugget case describes the time required for a hotel reservation call involving guest details, room, dates, party size and deposit. Task-specific context; the source does not establish a controlled AI-versus-human handling-time comparison.
What the Data Tells Us
Compare prices per minute with costs per completed task; add setup, telephony, failed automation and human transfers.
The 2016 missed-call study covered 85 businesses across 58 industries; it does not establish current revenue lost by your business.
Forrester modeled enterprise ROI and payback from four interviews; results depend on its composite assumptions.
DoorDash and Golden Nugget illustrate production deployments; their vendor cases do not establish industry-wide adoption, typical savings or guaranteed results.
