Part 1 of the series “What does an AI agent really cost?”
Copilot Studio is not charged at a flat rate “per agent”. The purchasing model, features and actual use determine the bill. The following information was reviewed on 8 September 2026 against Microsoft's billing documentation and August 2026 licensing guide. Prices are US list prices; contract, region, tax and exchange rate may differ.
Purchasing models
- Pay as you go (PAYG): USD 0.01 per Copilot Credit through an Azure subscription, without an upfront capacity purchase.
- Capacity pack: USD 200 per month, billed annually, for 25,000 Copilot Credits per month. Unused monthly capacity does not roll over.
- Copilot Credit Pre-Purchase Plan: a one-year upfront commitment with volume-dependent terms. Unused credits expire at the end of the term. Use the current quote rather than an assumed discount percentage.
The free Copilot Studio user licence for makers does not mean free production use. According to Microsoft's licensing page, the tenant needs an appropriate purchasing option; a trial lets a maker test an agent but not publish it.
Official consumption rates
| Capability | Consumption |
|---|---|
| Classic answer | 1 credit |
| Generative answer | 2 credits |
| Agent action | 5 credits |
| Tenant graph grounding | 10 credits |
| Agent flow actions | 13 credits per 100 actions |
| Basic / standard / premium AI tools | 1 / 15 / 100 credits per 10 responses; Microsoft also lists token-based rates |
Charges follow the billable capabilities that actually run. Use Microsoft's Usage Estimator and validate the result in a pilot. Microsoft states that the estimator is guidance, not a binding quote.
For example, 20,000 generative answers with no other billable capability use 40,000 credits, or USD 400 on PAYG. Actions, grounding and tools alter that result. A cost per 100, 500 or 1,000 registered users is therefore not reliable without measured interactions.
Formula: interactions × credits triggered × contracted credit price.
Dataverse capacity, premium connectors, external Azure or Foundry models, implementation, testing, operations and governance must be assessed separately. Bring-your-own-model use is billed separately. Generic implementation-day estimates and savings percentages are not evidence-based without a defined scope and baseline.
What Microsoft 365 Copilot includes
It is incorrect to say that a Microsoft 365 Copilot licence makes all agent use free. The footnote to Microsoft's billing-rates table includes business-to-employee scenarios when the interacting user is licensed for Microsoft 365 Copilot and the agent operates under that authenticated user's identity. Fair-use limits apply. Work IQ API usage is not included under the August 2026 guide, and agent flows are included only with the “When an agent calls the flow” trigger.
A public web agent or customer-facing agent is not that B2E scenario. Copilot Studio supports several channels, but identity, audience and licensing must be designed separately. A Microsoft 365 canvas is not the same as an external customer portal or anonymous B2C channel.
Nonprofit terms
Microsoft publishes a 15% discount on Microsoft 365 Copilot for eligible nonprofits. Its US page lists USD 25.50 per user per month, paid yearly, and still requires a qualifying Microsoft 365 base plan (Microsoft Nonprofits, reviewed 8 September 2026). This does not substantiate a free or specially discounted Copilot Studio credit rate. Eligibility and availability in Switzerland must be confirmed for the tenant and purchasing channel.
Conclusion
User count alone does not determine cost. Identity, channel, features and measured use do. A defensible estimate states these assumptions and replaces list prices with a current Microsoft or CSP quote before purchase.
