AI agents cost $0.05–$0.20 per minute for voice, $0.99–$2.00 per resolved chat conversation, or $300–$3,000 per month for a managed agent that handles one job — inbound call answering, lead qualification, appointment booking, review follow-up. One-time build fees run $2,500–$15,000 for a scoped agent and $25,000–$120,000 for multi-system enterprise deployments. If you self-host on a platform like Vapi, Retell, or Bland and wire it up yourself, a service business fielding 1,500 calls a month at 3.5 minutes each lands around $550–$900/month all-in. The spread is wide because "AI agent" describes everything from a $97/month chatbot to a six-figure contact-center replacement. Below is what each tier actually costs, and where the money leaks.

The Four Pricing Models You Will Be Quoted

Vendors price agents in four ways, and the model matters more than the sticker number.

  • Per-minute (voice). Platform fee plus pass-through costs. Bland lists around $0.09/minute bundled. Vapi charges roughly $0.05/minute for orchestration on top of your own speech-to-text (Deepgram Nova, ~$0.0043/minute), LLM tokens, and text-to-speech (ElevenLabs Flash, ~$0.03–$0.06/minute depending on plan). Add telephony: Twilio inbound local runs about $0.0085/minute, outbound about $0.014/minute, plus $1.15/month per phone number.
  • Per-resolution / per-outcome (chat and support). Intercom's Fin charges $0.99 per resolved conversation. Sierra and similar outcome-priced vendors negotiate per successful resolution, typically $1.50–$3.00. You only pay when the agent finishes the job — which sounds safe until you learn what counts as "resolved."
  • Per-action or credit-based. Salesforce moved Agentforce from $2.00 per conversation to Flex Credits at roughly $0.10 per action, sold in blocks (about $500 for 100,000 credits). A single customer interaction can burn 3–15 actions, so per-conversation cost is often $0.30–$1.50, not $0.10.
  • Flat monthly retainer. An agency or platform bundles the agent, the phone number, the integrations, and ongoing tuning. GoHighLevel's own tiers run $97 / $297 / $497 per month before AI usage (their Conversation AI adds about $0.02 per message and voice AI about $0.13/minute). Managed-service retainers on top of that generally run $500–$2,500/month per agent.
  • The trap in per-minute pricing: your average handle time is not your billed time. Silence, hold music, IVR navigation, and the 40 seconds a caller spends looking for their invoice number are all billed. Budget 15–25% above your historical average handle time.

    What a Real Monthly Bill Looks Like

    Small HVAC company, 400 inbound calls/month, 3-minute average. Self-serve voice agent at $0.12/minute all-in = $144/month in usage, plus a $1.15 phone number, plus $97–$297 for the CRM layer. Realistic total: $250–$450/month, after a $3,000–$6,000 build if someone else configures the booking logic and calendar integration.

    Multi-location medical practice, 4,000 calls/month, 4.2-minute average. 16,800 minutes at $0.11 = $1,848/month in usage. Add HIPAA-eligible infrastructure (BAAs typically push you to a higher tier, often +20–40%), plus a managed retainer of $1,500–$2,500. Realistic total: $4,000–$5,500/month. Compare against three full-time front-desk staff at $21/hour fully loaded ≈ $10,900/month.

    National franchise, 60,000 conversations/month across chat and voice. Enterprise contracts here land at $8,000–$30,000/month, with annual commits of $100,000–$360,000 and 12-month terms. Discounts of 20–35% are standard on annual prepay; almost nobody pays list.

    The Costs Nobody Puts in the Quote

    The platform invoice is usually 50–70% of true first-year cost. The rest:

  • Integration work. Connecting to ServiceTitan, Jobber, Housecall Pro, or a homegrown scheduler runs $2,000–$12,000 and is where most timelines slip. Budget 3–8 weeks, not the "live in 48 hours" you were sold.
  • A2P 10DLC and compliance. If your agent texts, US carrier registration costs a $4 one-time brand fee, roughly $10–$15/month per campaign, and adds $0.003–$0.005 per message in carrier fees. Rejected registrations delay launch by 1–3 weeks.
  • Human review. Plan on a person auditing 10–20% of transcripts for the first 90 days. At 1,500 calls/month, that's 6–10 hours/month of someone's time, or $300–$600.
  • Ongoing tuning. Prices change, services change, a new tech joins. Expect 2–5 hours/month of prompt and knowledge-base maintenance forever. Agencies bill this at $125–$250/hour or fold it into retainer.
  • The escalation tier. Containment rates of 60–80% are good. That means 20–40% of contacts still reach a human. You are not eliminating your answering service — you are shrinking it. Model both costs.
  • An agent at $0.12/minute with a 65% containment rate does not cost $0.12/minute. It costs $0.12/minute plus the human handling the other 35% — which is the number that decides whether this works.

    When an AI Agent Is a Bad Purchase

    This is where most pricing pages go quiet. Plainly:

  • Under roughly 200 inbound contacts a month, the math rarely works. A $4,000 build amortized over 12 months is $333/month in fixed cost against maybe 600 minutes of usage. A $1.25/call live answering service costs you $250/month with zero setup, zero maintenance, and no hallucination risk. Below about 250–300 calls/month, buy the answering service.
  • High-consequence conversations should not be automated first. Anything involving a binding quote, a medical triage decision, a legal deadline, or a dispatch that costs $800 if wrong. Current models still fabricate specifics at a low but non-zero rate — figure 1–4% of complex calls produce something you would not want a customer to hear. On 1,500 calls, that is 15–60 conversations a month. If your average job is $18,000, one bad quote wipes out a year of savings.
  • If your data is a mess, fix that first. An agent that books into a calendar with wrong service durations, or reads pricing from a 2023 PDF, produces confident wrong answers faster than a human could. Data cleanup is a $1,500–$8,000 prerequisite, not an optional add-on.
  • If your differentiator is that a human always answers, and you say so in your marketing, an agent can undercut the exact promise your customers pay a premium for. High-end residential and concierge services routinely see negative ROI here.
  • Latency kills conversion in some verticals. Even good voice stacks run 700ms–1.4s response latency. For emergency plumbing or restoration calls, that pause reads as hesitation. Test with real recordings before committing.
  • Churn risk in short-term pilots. A 30-day pilot on a 60–90 day sales cycle proves nothing. If your close cycle exceeds your pilot window, you will cancel a working system because the attribution has not landed yet. Commit to 90–120 days or don't start.
  • There is also a category we turn away: businesses buying an agent to avoid hiring when the real problem is that nobody follows up on leads that already came in. An agent that books 40 more appointments into a business that no-shows 30% of them adds cost, not revenue.

    How to Calculate Your Own Breakeven

    Run this before you take a single sales call:

    1.

    Cost per contact today. A CSR at $22/hour fully loaded handling 6 calls/hour = $3.67 per call. An answering service is typically $1.10–$2.25 per call at volume.

    2.

    Cost per contact with an agent. (Average minutes × per-minute rate) + (escalation % × your human cost per call) + (monthly fixed cost ÷ monthly contacts).

    3.

    Value of what you're recovering. Missed-call recapture is usually the biggest line. If you miss 12% of 1,500 calls and close 25% of the ones you answer at a $1,400 average ticket, that's 180 missed × 0.25 × $1,400 = $63,000/month in exposed revenue. Even recovering a third of it dwarfs the $450 agent bill.

    Step 3 is what actually justifies the purchase — not labor savings. If you cannot name a revenue leak in dollars, you are buying a cost center. Our ROI calculator runs this math with your numbers, and our pricing page shows what managed builds and retainers cost here without a discovery call.

    What to Ask Before You Sign

  • What is the all-in per-minute or per-conversation rate, including STT, TTS, LLM tokens, and telephony — not just the platform fee?
  • What containment rate did you achieve for a business like mine, and how do you define "contained"?
  • Is the build fee refundable if we don't hit an agreed containment or booking threshold in 60 days?
  • Who owns the prompts, the call recordings, and the phone number if we leave? (If the number doesn't port, you have no leverage.)
  • What does month 13 cost, once onboarding credits and first-year discounts expire?
  • For a deeper breakdown of how agency retainers are structured around this, see AI marketing agency pricing; for the voice-specific stack, our Bland AI implementation page covers what a production deployment includes.

    Short version: $250–$500/month if you're small and self-serve, $3,000–$6,000/month if you're mid-market and want it managed and reliable, $100,000+/year at enterprise scale — and $0 is the right answer if you're under 250 calls a month or your quotes carry real liability. The number that matters isn't the rate card. It's your cost per resolved contact against the revenue you're currently letting ring out.

    Frequently Asked Questions

    How much does an AI voice agent cost per minute?

    Voice AI agents run $0.05–$0.20 per minute all-in, covering speech-to-text, the language model, text-to-speech, and telephony. Self-hosting on Vapi, Retell, or Bland sits at the low end; managed vendors charge the high end. A business fielding 1,500 calls a month at 3.5 minutes each spends roughly $550–$900 monthly.

    What is a fair one-time build fee for an AI agent?

    Scoped single-purpose agents — inbound call answering, lead qualification, appointment booking — typically carry a $2,500–$15,000 one-time build fee covering prompt design, integrations, testing, and go-live. Multi-system enterprise deployments touching CRM, billing, and ticketing run $25,000–$120,000. Anything under $2,500 usually means a templated chatbot with minimal custom integration work.

    Is per-conversation or per-minute pricing cheaper?

    Per-resolution pricing ($0.99–$2.00 per resolved chat) is cheaper when volume is unpredictable or deflection rates are high, since you only pay for outcomes. Per-minute voice pricing wins at steady, high volume with short calls. Run both models against your actual monthly volume — the crossover usually lands between 800 and 2,000 interactions.

    What hidden costs come with AI agents?

    The common leaks are telephony and carrier fees billed separately, per-seat platform charges, overage rates once you exceed bundled minutes or conversations, and paid human escalation. Ongoing prompt tuning and integration maintenance add $300–$1,500 a month. Ask vendors for the fully loaded cost at your projected volume, not the headline rate.
