AI voice agent pricing in 2026–2027

AI voice agent pricing in the United States usually starts at $0.07–$0.99 per minute on public list pricing, but the usable all-in picture depends on what the vendor includes for telephony, speech, and language model costs. As of October 2026, the lowest public advertised minute rate in the comparison set is Retell AI at $0.07–$0.31 per minute and the highest public list minute rate is JustCall AI Voice Agent at $0.99 per minute, while all-in examples cluster from $0.082–$0.129 per minute at Vapi’s own 1,000-minute estimate to $0.49 per minute for RingCentral AI Receptionist standalone. For a cost baseline, US customer service representatives have a median wage of $21.53/hour, or $0.36 per paid minute, in May 2025 from BLS OEWS SOC 43-4051.

How much do AI voice agents cost per minute?

AI voice agent pricing varies widely because some vendors sell a platform layer only, while others bundle telephony or package minutes into plans. In public US pricing checked in October 2026, minute-based voice agent offers span from $0.07–$0.31 per minute at Retell AI to $0.99 per minute list pricing at JustCall AI Voice Agent, with several products sitting between about $0.08 and $0.35 per minute depending on volume and inclusions.

The most important distinction is billing unit. RingCentral AI Receptionist is $49/mo standalone for 100 min, which equals $0.49/min standalone, with overage at $0.50/min, verified October 2026 from RingCentral. Aircall AI Voice Agents lists $0.49/min PAYG, with bundles at $0.29–$0.35/min and from $0.19/min at 10,000+ min, verified October 2026 from Aircall. Bland AI lists Start at $0.14/min with $0 platform and Build at $299/mo + $0.12/min, verified October 2026 from Bland AI.

Per-minute pricing table

How we calculated this: when a plan included minutes, the effective rate is monthly fee ÷ included minutes. For example, RingCentral standalone is $49/mo ÷ 100 min = $0.49/min. When a vendor provided an all-in estimate directly, that estimate is shown without further adjustment.

In practice: if you are comparing ai voice agent pricing, first separate pure platform hosting from bundled minute pricing, or the cheapest-looking number may not be the cheapest invoice.

Platform fee vs all-in cost: what is included (LLM, voice, telephony)

The headline rate often does not equal the final call cost. Some vendors include most components inside the minute price, while others charge hosting and pass through speech-to-text, text-to-speech, large language model, telephony, or transfer usage separately.

Retell AI lists $0/mo platform and $0.07–$0.31/min, but also shows extra costs including a phone number at $2/mo, premium voices, and extra concurrency at $8/mo, verified October 2026 from Retell AI. Vapi lists $0.05/min hosting, with STT/LLM/TTS at cost and HIPAA at $2,000/mo, verified October 2026 from Vapi. ElevenLabs Agents shows $0.08/min excluding LLM costs and burst minutes at $0.16/min, verified October 2026 from ElevenLabs.

A second issue is transfers and telephony treatment. Bland AI notes transfer time at $0.04–$0.05/min and that telephony treatment is unclear because the pricing page and docs disagree, verified October 2026 from Bland AI. Aircall notes seat licenses if using its phone system, verified October 2026 from Aircall. JustCall states its AI Voice Agent requires a JustCall subscription with a minimum of 2 licenses, verified October 2026 from JustCall.

An example of a more transparent structure is per-second, talk-time-only billing where hold, waiting, and idle time are not billed; that matters when callers spend time in queue or during handoffs.

In practice: ask every ai voice agent platform vendor for a sample bill that shows minute charges, telephony, transfers, phone numbers, minimums, and any compliance add-ons.

Which voice agent is the cheapest?

There is no single cheapest voice agent without a call-length assumption and a clear definition of what is included. On public minute pricing alone, Retell AI shows the lowest advertised floor at $0.07/min, but Vapi shows a lower all-in estimate than many bundled products at $0.082–$0.129/min for 1,000 minutes, while JustCall’s public list rate is the highest at $0.99/min before volume discounts.

The answer changes if the billing unit is not per minute. Smith.ai AI Receptionist is $150/mo for 75 calls, or $2.00/call, verified October 2026 from Smith.ai. Upfirst is $24.95/mo for 30 calls, or $0.83/call on Starter to $0.53/call on Pro, verified October 2026 from Upfirst. Dialpad AI Agents is $1.99 per voice conversation, verified October 2026 from Dialpad. Those can be cheaper or more expensive than minute pricing depending on average call length.

Why unit economics can mislead

• A per-call product can look cheap on short calls and expensive on long calls.
• A per-minute product can look expensive if many calls end in under 30 seconds but are rounded up.
• A hosted platform can look cheap until model and telephony pass-through fees are added.

In practice: define your own average call length, transfer rate, and monthly minute volume before calling any product the best ai voice agent on price.

Per-second vs per-minute billing: how rounding changes the bill

Billing granularity can materially change ai call center cost even when list rates look similar. Per-second billing generally tracks actual talk time more closely, while per-minute or partial-minute rounding can inflate billed usage on short calls.

RingCentral AI Receptionist bills in 30-second increments, rounded up, verified October 2026 from RingCentral. Retell AI bills per second with no rounding per call, verified October 2026 from Retell AI. Bland AI documentation states per-second billing, verified October 2026 from Bland AI. Yulio also states per-second billing and that hold and idle time are not billed, verified October 2026 from Yulio.

Rounding example: 1,000 calls of 2m10s billed per second vs per minute

How we calculated this: 2m10s equals 130 seconds. For 1,000 calls, 130 seconds × 1,000 = 130,000 seconds. Then 130,000 ÷ 60 = 2,166.7 minutes under per-second billing. Under full-minute rounding, each call becomes 3 billed minutes, so 1,000 × 3 = 3,000 billed minutes.

In practice: if your calls are short, billing granularity can matter almost as much as the published rate.

Cost at contact-center scale: 10,000 to 100,000 minutes a month

At higher volumes, the useful comparison is not entry pricing but marginal minute rate and what operational extras are already included. Public data shows some meaningful volume discounts, but enterprise pricing is often partially or fully undisclosed.

Aircall AI Voice Agents lists from $0.19/min at 10,000+ min, verified October 2026 from Aircall. JustCall AI Voice Agent says pricing goes down to $0.15/min at volume, verified October 2026 from JustCall. Yulio states enterprise volume pricing starts from $0.12 per minute, verified October 2026 from Yulio. Synthflow lists from $30,000/year with volume and integrations scoped commercially, verified October 2026 from Synthflow. PolyAI pricing is not public and requires contact sales, verified October 2026 from PolyAI.

For a labor comparison, US customer service representatives have a median wage of $21.53/hour, or $0.36 per paid minute, in May 2025 from BLS OEWS SOC 43-4051. US receptionists have a median wage of $18.27/hour, or $0.30 per paid minute, in May 2025 from BLS OEWS SOC 43-4171. ContactBabel reports an average cost of an inbound call of $7.20 in 2026 in the United States.

Scale snapshot

In practice: at contact-center scale, ask vendors to show whether concurrency, support, reporting, integrations, and compliance are included or sold separately.

How to choose an AI voice agent platform

The right platform depends less on list price and more on billing logic, integration fit, and whether the product matches your call shape. A neutral buying checklist is to compare the charging unit, what is bundled, the rounding rule, and the extra fees that appear only after deployment.

A practical checklist

1. Confirm the billing unit: per minute, per second, per call, per conversation, or per unique caller.
2. Confirm whether telephony, STT, TTS, and LLM charges are included or passed through.
3. Check rounding rules and whether transfers, hold time, or idle time are billed.
4. Ask for minimum monthly fees, phone number charges, and concurrency charges.
5. Check whether seat licenses or a base subscription are required.
6. Validate compliance and add-on costs such as HIPAA if relevant.
7. Request an invoice simulation at your expected monthly volume.

If you are also comparing packaged receptionist tools, see AI receptionist monthly plans. If you need the wage baseline and service comparison, use AI vs human cost comparison. For the wider benchmark view, start at the AI call center cost overview.

In practice: the cheapest ai call center software on paper is often the one with the most assumptions missing, so force the comparison into the same usage scenario before deciding.

What is declining?

Search interest is shifting away from older receptionist terminology toward AI-led categories. US search data from Google Trends, October 2026, shows interest for “ai receptionist,” “ai call center,” and “ai voice agent” rose from near zero before 2024 to first-half 2026 half-year averages of 47, 65, and 58 on a 0–100 scale, while “virtual receptionist” stayed flat at 5–19. Separate US search data in October 2026 indicates “virtual receptionist” searches fell about 72% year over year while AI-labeled queries grew.

In practice: buyers are increasingly shopping under ai voice agent pricing and ai call center cost terms rather than older answering-service labels, even when the use case overlaps.

Bottom line

• Public US pricing checked in October 2026 ranges from $0.07–$0.99 per minute, but all-in cost depends on whether telephony, LLM, and voice are included.
• Billing granularity matters: per-second billing can materially reduce billed minutes versus rounded minute plans on short calls.
• At higher volumes, ask for a scenario-based quote using your minutes, call length, and transfer pattern before comparing vendors side by side.
