What does an AI agent cost? Prices and examples
By Philipp Kant 5 min read
An AI agent costs two things: the build, once, and the model calls for every task it handles. For an agent that works inside an ERP, PIM, or CRM, the build costs between €4.5k and €45k at a fixed price with us. The running cost is usually a few cents per task. Whether it pays off depends on the number of tasks.
Prices as of November 9, 2026. Model prices are the vendors’ list prices in US dollars and change several times a year.
The two cost blocks: build and running
| Block | What it covers | Typical size |
|---|---|---|
| Build (one-time) | clarifying the workflow, connecting the systems, rules and approvals, evaluation, handover | €4.5k to €45k |
| Model calls (running) | language model calls per task | a few cents per task |
| Operations (running) | hosting, monitoring, adjustments when the systems change | small, often on an existing server |
| Subscriptions (optional) | office agents per seat, such as Claude Team | about 20 to 25 US dollars per seat and month |
What makes the build cheaper or more expensive
The model does not drive the price; the work around it does:
- Number of systems: an agent that only reads an inbox is faster to build than one that writes into the ERP, PIM, and CRM.
- Data quality: if values are missing or sources contradict each other, the cleanup comes on top.
- Approvals and evaluation: rules for who approves what, and a test set of real cases the agent is measured against.
- Channel: a voice or chat channel for customers costs more than an agent working in the background.
Our fixed-price ranges per service: AI agents €4.5k to €45k, process automation €3.5k to €30k, CRM and ERP integration €6k to €45k. What makes an integration expensive is covered in The hidden costs of CRM/ERP integrations.
Running costs: what one task costs
Models bill by tokens, roughly by amount of text, split into what goes in and what comes out. List prices per million tokens:
| Model | Input | Output | Typical use |
|---|---|---|---|
| Claude Haiku 5.5 | $0.10 | $0.50 | sorting, extraction, simple answers |
| Claude Sonnet 5.5 | $2 | $10 | agents with several steps |
| Claude Opus 5.5 | $4 | $20 | hard cases, long tasks |
Worked example, order entry (assumptions): an order arrives as an email with a PDF. The agent reads it, checks the items in the PIM, creates the order in the ERP, and drafts the reply. Across all steps that is about 30,000 input tokens and 3,000 output tokens. With Sonnet 5.5 that costs about 9 US cents per order, about €35 for 400 orders a month. With Haiku 5.5 for the extraction alone, that step drops below one cent.
For comparison, a public field report: a business let an agent answer its sales texts, 911 conversations for 110 US dollars, about 12 cents per conversation (r/AI_Agents, November 2026).
When an agent pays for itself
The calculation has three numbers: tasks per month, minutes per task today, and the hourly cost of the person who does it today.
| Worked example | Value |
|---|---|
| Orders per month | 400 |
| Minutes per order today | 6 |
| Working time per month | 40 hours |
| at €45 per hour | €1,800 a month |
| Model calls per month | about €35 |
| Fixed-price build (assumed) | €9,000 |
| Build paid back after | about 5 months |
The first number matters most: at 40 tasks a month, the same agent takes years to pay off. A workflow that runs dozens of times a day is the better first candidate. Which workflows those are is covered in 10 questions before your first AI agent project.
Where costs run away
According to the KPMG Global AI Pulse (Q2 2026), 49 percent of surveyed leaders delayed or scaled back an agent once its costs outgrew its value. The usual causes:
- No limit: nobody sets a monthly budget, so nobody notices an agent stuck in a loop.
- Too big a model for every step: the most expensive model also sorts emails the cheapest one sorts just as well.
- AI where a rule would do: checks like “field empty” or “number out of range” run without a model, for free and faster.
- Agents commissioning agents: several agents passing work back and forth multiply the calls.
What helps: a monthly limit you set, the smallest model that passes the test set, caching for repeated instructions, and fixed rules before every model call.
FAQ
What does an AI agent cost for a small business? An agent for a single workflow, such as pre-sorting the inbox, sits at the lower end of our range, from €3.5k to €4.5k to build, plus model costs of a few euros a month.
What does an AI agent cost per month? Model costs depend on the number of tasks: a few cents per task, about €35 for 400 orders in the worked example. Hosting and monitoring come on top, often on an existing server.
Isn’t a subscription like Claude Team cheaper? For personal work with email and documents, yes. For a workflow that writes into the ERP and needs approvals, it does not replace the build. The difference is explained in Office AI agents: Cowork, ChatGPT Work, and more.
How do I keep costs from rising? With a fixed monthly limit, the smallest model that passes the test set, and rules without AI wherever a rule will do.
