Short answer: an AI voice agent costs between $0.10 and $0.50 USD per minute of conversation, plus a one-time setup of $100 to $2,000 USD. At Fluxr, the price is S/ 0.76 per minute with a one-time S/ 1,699 setup — no monthly minimums and no lock-in contracts. A business handling 1,000 minutes of calls a month invests around S/ 760 — versus the $600–$1,500 USD a single human agent costs in Latin America (figures are in different currencies).
Now the full answer, because "per minute" hides enormous differences between vendors.
What the per-minute price includes (and what it doesn't)
The cost of an AI voice agent is made up of four technical layers. When a vendor quotes you a price, always ask which of these are included:
| Component | What it does | Usually included? |
|---|---|---|
| Speech recognition (STT) | Transcribes what your customer says | Yes |
| Language model (LLM) | Understands and decides what to answer | Yes, but quality varies |
| Speech synthesis (TTS) | The voice your customer hears | Yes — premium voices cost more |
| Telephony (the number and the call) | Connects the actual call | Often NOT — can add $0.01–$0.05/min |
At Fluxr, the S/ 0.76/min covers all four layers. If a vendor offers you $0.08/min, telephony, integrations or natural voices are almost certainly billed separately.
Pricing by volume: 3 real scenarios
Using Fluxr's pricing (S/ 0.76/min, S/ 1,699 setup):

| Clinic or local business | 300 min (~100 calls) | S/ 228 | S/ 4,435 |
| Growing SMB | 1,000 min (~350 calls) | S/ 760 | S/ 10,819 |
| High-volume operation | 5,000 min (~1,700 calls) | S/ 3,800 | S/ 47,299 |
*Includes the S/ 1,699 setup. No hidden costs: no minimums, no per-extra-agent charge, no fee for WhatsApp or CRM integration.

AI voice agent vs human agent: the full math
| Item | Human agent (Latin America) | AI voice agent |
|---|---|---|
| Monthly cost | $600–$1,500 USD + benefits | From S/ 228 (pay as you go) |
| Hours | 8 hours, 5-6 days | 24/7/365 |
| Simultaneous calls | 1 | Unlimited |
| Response time | Depends on the queue | Answers on the first ring |
| Holidays, turnover, training | Yes (a real hidden cost) | Not applicable |
| Empathy in complex cases | Superior | Hands off to a human with context |
Fluxr prices are in Peruvian soles (S/); human agent cost is in USD. The cost difference remains significant at any exchange rate.
The honest conclusion: AI doesn't replace 100% of your team — it replaces 70-90% of repetitive calls (opening hours, appointments, order status, FAQs) so people can handle the cases that genuinely need human judgment. That's the scenario where the 70% cut in operating costs we documented in our case studies is achievable.
The 3 hidden costs to ask about before you sign
- Monthly minimums. Some vendors charge $200-500/month even if you receive no calls. If your volume fluctuates, insist on pure pay-as-you-go.
- Per-agent or per-number charges. Need one agent for sales and another for support? Some vendors bill each one separately. At Fluxr agents are unlimited within the same setup.
- "Premium" integrations. Connecting your CRM, WhatsApp or calendar shouldn't be an upsell — without integration the agent only answers questions and books or records nothing.
How much does implementation cost, and how long does it take?
Market setup ranges from $100 (generic templates you configure yourself) to $2,000+ (enterprise agencies). Fluxr's S/ 1,699 setup includes a 30-minute discovery call, building the knowledge base with YOUR information, an optimized prompt, calendar integration and testing — the agent is handling real calls within 48 hours.
How to test it without paying anything
The fastest way to judge whether an AI voice agent works for your business is to hear it answer a call of your own:
- Try the live demo — the agent calls you in under a minute and talks with you in English, Spanish or Portuguese.
- Compare the full plans for voice, chat and automations.
- Complex case or high volume? Message us on WhatsApp and we'll put together a tailored quote the same day.
