“How much does an AI voice agent cost?” is the first question every business asks — and the honest answer is “it depends on minutes, integrations and how much it needs to do.” This guide breaks the price into its real components so you can budget with confidence.
The 5 components of AI voice agent pricing
1. Telephony
Phone numbers and call minutes from providers like Twilio. A US local number costs a little over a dollar per month, and voice minutes are typically around a cent or two per minute.
2. Speech-to-text (STT)
Real-time transcription of the caller. Usually fractions of a cent per minute.
3. The LLM “brain”
The language model that understands and decides what to do (Claude, GPT-class models). Cost depends on conversation length and model choice — often a few cents per call.
4. Text-to-speech (TTS)
Natural voices from providers like ElevenLabs. Premium voices are one of the larger per-minute costs, so voice choice matters at scale.
5. Build & integration
The one-time work: scripts, calendar and CRM integrations, transfers, testing, compliance. This is where agency pricing lives.
Typical all-in pricing
| Item | Typical range |
|---|---|
| Setup (custom agent + integrations) | $3,500–$15,000 |
| Usage (all providers combined) | ~$0.08–$0.25 per minute |
| Platform / maintenance | $200–$1,000 / month |
A business handling 2,000 minutes per month might spend a few hundred dollars on usage. Compare that with the cost of staffing the same coverage 24/7.
How to calculate ROI
Use this simple formula:
Monthly ROI = (extra bookings × average job value × close rate) + (staff hours saved × hourly cost) − monthly AI cost
Example: a home-services company recovers 40 missed calls per month, books 15 of them at a $450 average ticket. That’s $6,750 in recovered revenue against a few hundred dollars of usage.
What drives the price up?
- Complex integrations — legacy software without APIs.
- Outbound campaigns — consent tracking, DNC scrubbing and compliance logic under the TCPA.
- Healthcare — HIPAA-eligible infrastructure and BAAs.
- Custom voices and multilingual support.
Build vs. buy
Off-the-shelf tools are fine for simple FAQ lines. If you need real booking, CRM updates, warm transfers and reporting, a custom agent on a production platform pays for itself quickly. Our agents run on Voxiqo, the voice platform we built and operate — so you get a custom agent without paying to build the infrastructure from scratch.
