Copilot Credits: how to estimate and cap the cost of your Microsoft agents

Since Copilot Cowork became generally available in June 2026, some advanced Microsoft 365 experiences combine a user license with consumption-based billing. For IT and procurement teams, the question has moved from “how many licenses?” to “how many credits a month, and who is spending them?”. This guide explains how to estimate that budget before enabling usage-based billing, and how to keep it under control once agents are in production. For the cost and return on investment of Cowork specifically, see our Copilot Cowork pricing guide: this article focuses on estimating, capping and tracking spend, especially for Copilot Studio agents.

What is a Copilot Credit?

A Copilot Credit is the unit Microsoft uses to bill its AI features on consumption. Microsoft describes it as a common currency across its usage-based services, pooled at the tenant level. As of October 2026, its Copilot Credits Guide lists, among others:

• Experiences that require a Microsoft 365 Copilot license: Copilot Cowork, Copilot Code (offered through the Frontier program) and advanced Copilot features in SharePoint.
• Services available without an individual Copilot license: Work IQ APIs for custom apps and agents, Teams Phone Agent, and Copilot Managed Runtime, in paid preview, which hosts and runs apps built with Cowork, Copilot Studio or third-party tools.
• Agents and Power Platform solutions: agents built with Copilot Studio, Dynamics 365 agents and AI features in Power Apps and Power Automate.

These services do not all share the same prerequisites or admin console: Cowork and Microsoft 365 services are managed in the Microsoft 365 admin center, Copilot Studio capacity in the Power Platform admin center.

Autopilot, announced in late September 2026 and still in private preview, is not yet on this list.

For the first group, the license grants access and usage is billed in credits. Note that Microsoft documentation currently uses both “Microsoft Copilot” and “Microsoft 365 Copilot” depending on the offer and the page. We use “Microsoft 365 Copilot” for the user license to avoid ambiguity.

How much does a credit cost?

Microsoft offers three ways to buy credits.

On mobile, swipe the table to the left to see every column.

These are list prices in US dollars. For licenses purchased through a reseller, the price is set by the reseller. When a spending policy combines these three sources, Microsoft applies consumption in the following order: capacity packs, then P3 pre-purchase, then pay-as-you-go.

What changes on December 1, 2026

In September 2026, Microsoft announced that new Microsoft 365 Copilot Business licenses would have usage-based billing enabled by default. On October 1, in Message Center (MC1476200) and Partner Center, Microsoft clarified the timeline: the change will apply from October 19, 2026 to purchases made directly from Microsoft, and from December 1, 2026 to purchases made through a CSP reseller, instead of the November 2 date first announced. Both dates are still ahead at the time of writing.

The default spending limit will be 4,000 credits per user per month, and admins can change it. It is a limit, not a charge: only actual consumption is billed. At the $0.01 list price, this limit represents up to $40 per user per month.

Existing subscriptions will keep their terms. For eligible new Microsoft 365 Copilot Business purchases, usage-based billing will be preconfigured by default at the tenant level, with a monthly limit that admins can change.

Microsoft says this default will initially not be available in eleven markets: Australia, Belgium, Brazil, France, Germany, India, Italy, Korea, the Netherlands, Poland and Spain. No date has been announced for these markets.

If your organization has entities in a market where the default applies, set your limits before they buy new Copilot Business seats. Otherwise, each new license may consume up to 4,000 credits a month without an explicit decision.

Estimate your usage in four steps

1. Identify the usage that is actually billed. For internal, employee-facing scenarios with agents built with the Standard or Copilot Chat harness of Copilot Studio and used in Microsoft channels (Teams, Copilot Chat, SharePoint), usage carries no additional charge when the employee holds a Microsoft 365 Copilot license and the agent runs with their authenticated identity, within fair usage limits that Microsoft may update. The following remain billable, even for these employees: agents built with the new GitHub Copilot harness of Copilot Studio, Work IQ API calls and, according to Microsoft’s documentation, agent flows started by a trigger other than the agent and computer use. Most of the spend therefore comes from employees without a Copilot license, from Cowork and from Work IQ integrations.

2. Apply the published rates. For agents built with the Standard harness of Copilot Studio, Microsoft publishes its rates by operation:

One question can combine several operations. The “tenant graph grounding” item corresponds to a semantic search option, billed as an extra, that must be turned on for users without a Copilot license. A standard SharePoint knowledge source is billed as a generative answer, that is 2 credits. Microsoft cites the example of an agent using this option: 12 credits to answer one complex prompt, 10 for grounding and 2 for the generative answer. Reasoning models, AI tools (prompts) and voice agents follow additional rates, calculated in tokens or minutes. Agents built with the GitHub Copilot harness are billed differently, based on the model, runtime, context and tools.

3. Multiply by your volumes. A worked example using these rates: 500 employees without a Copilot license each ask an HR agent based on SharePoint four questions a week, about 8,700 questions a month. With a standard SharePoint source, at 2 credits per answer, consumption reaches about 17,300 credits, or roughly $173 a month on pay-as-you-go. With the semantic search option turned on, at 12 credits per question, it reaches about 104,000 credits, or roughly $1,040 a month. Each agent action, such as a tool call, adds 5 credits. This calculation assumes a single generative answer per question: a real interaction can trigger several billed operations.

4. Measure on a pilot. For Cowork, Microsoft does not publish a fixed price per task, only indicative ranges: the cost depends on the model, the context consulted, the tools called and the runtime. The most reliable approach is to run a pilot of a few weeks with a limited group of users. In Cowork, the /cost command shows the approximate credit cost of the current task and how much of the monthly limit is left; using it does not consume credits, but it is not a billing record. To estimate in advance, Microsoft provides two estimators: the Copilot Credit Estimator for Cowork, and a dedicated estimator for Copilot Studio agents, for which Microsoft recommends adding a 10 to 20% buffer.

Set limits: three places, three behaviors

On mobile, swipe the table to the left to see every column.

To get started, we recommend three settings:

1. A monthly limit per user. Microsoft recommends it to prevent a single user from consuming the entire budget.
2. Alerts at 50% and 80% of the budget, sent to the license owner and the finance contact.
3. A dedicated limit, with a hard stop, for every Copilot Studio agent opened to a wide audience, as these agents show the fastest growth in consumption.

Track costs agent by agent

Three dashboards work together:

• Cost Management in the Microsoft 365 admin center: Overview and Consumption tabs, with views by policy, user, group, agent and service, and a Top actions panel that gathers users’ credit requests.
• The Credits report (Reports > Usage > Microsoft Copilot): credits used by pay-as-you-go agents in Copilot Chat, per user, per agent and per billing policy, over 7 or 30 days, exportable to CSV.
• Azure Cost Management: pay-as-you-go consumption appears on the “Microsoft Copilot Studio – Pay As You Go Copilot Credit” meter, with up to 24 hours of delay.

A monthly review is generally sufficient. It covers the ten agents that consume the most, the users close to their limit, and the agents without a clear owner.

Three best practices to keep spending under control

Know which agents exist before you cap them. In a tenant, agents are created in Copilot Studio, in Agent Builder, in SharePoint or in code (Microsoft Foundry, Agents SDK), and many become unused or redundant. An up-to-date inventory allows you to set limits on an informed basis.

Compare licenses and credits for intensive users. For an employee with a Microsoft 365 Copilot license, internal Copilot Studio agents carry no additional charge in eligible scenarios. Above a certain volume, the license can cost less than the credits that person would use.

Prefer a fixed price when volume is predictable. For highly repetitive use, such as every employee’s HR or IT questions, a tool billed per user provides greater budget predictability than usage-based billing.
