What actually counts in "AI cost"
The headline number every vendor quotes — GPT-4o at $2.50 per million input tokens — is one line in a 12-line bill. The real all-in monthly cost of a production AI agent includes:
- LLM inference (the part everyone quotes): 15–35% of total
- Telephony / messaging carrier (Twilio, Telnyx, Vonage): 10–30%
- STT / TTS for voice: 8–18%
- Vector DB / RAG infrastructure: 5–15%
- Observability + evals (LangSmith, Helicone, Arize): 4–10%
- Hosting + queues (Render, Railway, Modal, AWS): 5–12%
- Tool-call API fees (CRM writes, calendar checks, payment APIs): variable
- Human review (when present): 5–15%
Every number below is fully loaded — meaning if you read "$340/month for a website chatbot" that's the actual all-in number, not just the OpenAI line item.
Website chatbot — typical monthly cost
| Volume | Avg conversations/mo | Typical all-in cost |
|---|---|---|
| Low traffic (B2B site) | 500 | $80–$180 |
| Mid traffic (DTC, services) | 5,000 | $280–$640 |
| High traffic (SaaS, e-comm) | 50,000 | $1,800–$4,200 |
| Enterprise | 500,000+ | $12K–$38K |
The biggest single driver isn't model choice — it's whether you've built in conversation termination logic. Chatbots that don't know how to politely end a conversation cost 2–3x more.
Voice agent — typical monthly cost
| Volume | Minutes/mo | Typical all-in cost |
|---|---|---|
| Pilot (single use case) | 2,000 | $320–$520 |
| Small biz inbound | 10,000 | $1,200–$2,400 |
| Mid-market contact center | 100,000 | $9K–$18K |
| Enterprise | 1M+ | $70K–$180K |
All-in voice cost lives between $0.09 and $0.22 per minute for published-pricing platforms (see our voice AI benchmark). Enterprise platforms charge 3–5x that.
AI SDR (outbound sales agent) — typical monthly cost
| Leads contacted/mo | Cost per lead | Monthly all-in |
|---|---|---|
| 1,000 | $0.45–$0.90 | $450–$900 |
| 10,000 | $0.18–$0.42 | $1,800–$4,200 |
| 100,000 | $0.08–$0.22 | $8K–$22K |
Costs include data enrichment (Clay, Apollo), sending infrastructure (SendGrid, Instantly), and the agent itself. The variance is driven by how many touches per lead — most B2B sequences are 6–8 touches over 21 days.
Support ticket deflection — typical monthly cost
| Tickets handled/mo | Cost per deflected ticket | Monthly all-in |
|---|---|---|
| 1,000 | $0.30–$0.65 | $300–$650 |
| 10,000 | $0.18–$0.40 | $1,800–$4,000 |
| 100,000+ | $0.10–$0.25 | $10K–$25K |
Average human-handled ticket costs $7–$24 fully loaded. AI deflection lands at 5–10% of that — which is why this is the single most predictable ROI in the AI ops category.
Content generation (blog posts, ads, social) — typical monthly cost
For publishing teams generating 50–500 long-form pieces a month, all-in cost runs $400–$3,200/month including evals, fact-checking passes, and image generation. The "ChatGPT can do this for $20" framing assumes zero quality control — which is why those workflows produce content nobody actually publishes.
RAG / internal knowledge agent — typical monthly cost
| Document corpus | Queries/mo | Monthly all-in |
|---|---|---|
| 10K documents | 5,000 | $240–$520 |
| 100K documents | 50,000 | $1,400–$3,200 |
| 1M+ documents | 500K+ | $11K–$28K |
Embedding storage is cheap. Re-indexing is expensive — most overruns come from re-embedding the entire corpus weekly when a delta-update would have cost 5% as much.
Workflow automation (back-office AI) — typical monthly cost
For document-extraction, AP automation, intake processing, or any "shape unstructured input into structured output" pattern: typical cost is $0.03–$0.12 per processed document including LLM, OCR, and validation. A mid-market firm processing 10,000 invoices/month spends $300–$1,200 vs. $40K–$100K of human AP labor for the same throughput.
Total cost of ownership — the 3-year math
For a typical mid-market deployment (4 production AI workflows, ~$2,000/month run-cost), the 3-year TCO breakdown looks like:
- Initial build (agency or internal): $30,000–$80,000 one-time
- Monthly run-cost: $2,000/month × 36 = $72,000
- Maintenance + iteration (10–20% of build/yr): $9,000–$48,000
- 3-year all-in: $111K–$200K
Comparison: one full-time mid-level operations hire at $85K/year fully loaded = $255K over 3 years, and you still need the AI infrastructure. The pricing math almost always favors AI when the workflow is repetitive and well-bounded. The math reverses when the workflow needs judgment in cases the AI has never seen — which is why we always recommend human-in-the-loop architecture for anything customer-affecting.
