Agentic AI Total Cost of Ownership

The eight cost lines a CFO will ask about, with three illustrative year-one TCO calculations.

Eight cost lines

  • Platform
    The vendor's published or quoted rate. Typically 20 to 60% of year-one TCO.
  • Tokens
    Underlying LLM cost. Forecasted from token-per-interaction x volume x model rate.
  • Compute
    Sandbox runtimes, browser-use, vector store. Often missed in vendor demos.
  • Eval and observability
    Tracing, regression evals, prompt-version control. LangSmith, Braintrust, Arize.
  • HITL review time
    Human-in-the-loop hours for the first 90 to 180 days. Often 0.25 to 0.5 FTE.
  • Integration
    Connectors to CRM, ticketing, knowledge base, identity provider.
  • Change management
    Internal training, documentation, escalation paths.
  • Support and uplift
    Ongoing prompt tuning and quarterly model upgrades.

$360,000
06Integration

07Change management

Year-one TCO~$2,310,000

Rule of thumb

~2.3x
TCO multiplier
Median ratio of year-one TCO to platform list price across the three bands above ($277.7K / $120K mid; $2.31M / $1.2M enterprise; small band excluded as platform is < 1% of TCO)
30-40%
Non-platform cost share
HITL + integration + change typically here
6-12mo
Payback
Where deflection-rate uplift matures
Year 2+
Marginal cost
Drops materially as integration and change are amortised
