What is public

Microsoft's agentic AI (the Index-relevant scope) has substantial PUBLIC pricing. Copilot Chat: free with an eligible M365 subscription (web-grounded, enterprise data protection). Microsoft 365 Copilot Business (up to 300 users): $18/user/mo promotional (standard $21 from July 1, 2026), add-on to an M365 Business plan. Microsoft 365 Copilot (Enterprise): $30/user/mo (annual), add-on to E3/E5/Business Standard/Premium - includes Copilot across Office apps + Work IQ + internal-agent building. Copilot Studio (agent builder): internal agents free for licensed users; EXTERNAL agents billed by messages/credits ($200/mo per 25,000 messages, overage $0.01-$0.02/message). Dynamics 365 Copilot + enterprise agreements are custom-quoted.

Billing mechanics

Copilot is an ADD-ON, not standalone - you must hold a qualifying base M365 license, so true cost = base plan + Copilot (e.g., E3 $36 + Copilot $30 = $66/user/mo; E5 + Copilot = $87). The Copilot seat license is per-user/month (annual commitment for Enterprise). Agent building runs on a separate CONSUMPTION model: Copilot Studio external agents bill by message/credit - a $200/mo pack = 25,000 messages, then $0.01/standard and $0.02/generative message, with premium messages (Dataverse, third-party connectors, complex Power Fx) billed at multiples; also available pay-as-you-go via Azure (Copilot Credits, Azure subscription required) or prepaid Commit Units (up to 20% off).

Variable cost rationale

Two layers: fixed per-seat Copilot licenses (predictable) PLUS highly variable agent-message consumption (Copilot Studio) that scales with interaction volume x message type (premium/connector messages multiply cost); large agent fleets are where spend becomes unpredictable and large

Additional watchouts

Budget the all-in (base + Copilot), not the add-on headline; external-agent message costs are the sleeper line item (premium/connector messages multiply fast); 'Copilot' SKU sprawl causes mis-purchasing (consumer vs work, Business vs Enterprise, included vs standalone Studio); promotional/EA pricing has expiration cliffs; requires Azure for agents

Overage / add-ons

Copilot Studio external-agent messages over the 25,000/$200 pack bill at $0.01/standard and $0.02/generative message; premium messages (line-of-business connectors, Dataverse, complex evaluations) consume multiple messages each - large agent fleets can run into the tens-to-hundreds of thousands/mo at list. Azure PAYG auto-covers when prepaid credits run out. Seat licenses are fixed per-user/month (annual).

Sales call required

Mixed (some tiers require a call)

Commercial notes

Index-relevant agentic surface = Microsoft 365 Copilot + Copilot Studio (low-code agent builder) + Copilot agents + Dynamics 365 Copilot; >90% of Fortune 500 deployed Copilot by 2026; Agent Mode GA in Word/Excel; GPT-5.x + model choice in Copilot/Studio; Forrester cites 116% enterprise / 353% SMB 3-yr ROI; competes with Google Gemini Enterprise, ChatGPT Enterprise, Claude Enterprise, Salesforce Agentforce

Key ambiguities

Pricing changes frequently (a July 1, 2026 change moves several numbers; Business promo $18 to $21, and base-license increases take effect; enterprise volume discounts expire June 30, 2026); 'Copilot' is a family, not one SKU (Chat/Business/Enterprise/Studio/vertical SKUs/consumer Premium); Dynamics 365 Copilot and Enterprise Agreement pricing are quote-based (volume discounts negotiated); exact premium-message multipliers for Copilot Studio aren't fully published; a new M365 E7 Frontier suite (~$99/user/mo, bundles E5 + Copilot + Agent 365) launched 2026.

Cancellation / refund

Copilot Chat free (with eligible M365 sub); M365 Copilot add-ons require annual commitment (7-day prorated-refund cancellation window on some Business offers); Copilot Studio packs monthly or Azure PAYG (no commitment); Enterprise Agreements custom-negotiated; base M365 license required throughout

Support SLA / resale

Standard Microsoft support tiers (by base plan); enterprise governance via Purview, identity via Entra; enterprise data protection (data stays in tenant, no model training); Microsoft Graph grounding; sold direct, via resellers, or Cloud Solution Provider partners; Azure subscription required for agents

Missing data

Dynamics 365 Copilot and Enterprise Agreement pricing are quote-based (vary by existing licensing and volume); exact Copilot Studio premium-message multipliers aren't fully published; vertical-SKU bundling shifts over time. Heads-up: effective July 1, 2026, M365 Copilot Business rises from $18 to $21/user/mo and base-license prices increase; enterprise volume discounts expire June 30, 2026.
