Microsoft 365 Copilot Licensing Explained (2026): Copilot Chat, the $30 Add-On, Copilot Business, Agents and Credits

Copilot licensing is the part of Microsoft 365 licensing that changes fastest and costs the most per seat. There is a free chat experience, a $30 per user add-on, a cheaper version for smaller organizations, a bundle that includes it, and a separate usage-based meter for agents. Microsoft also renamed the product: Microsoft 365 Copilot is now called Microsoft Copilot, and Microsoft 365 Copilot Chat is now Microsoft Copilot Chat. This guide explains what each option includes, what you need before you can buy it, how agents and Copilot Credits are billed, and how to buy only the seats you will actually use. It builds on our Microsoft 365 licensing guide, which covers the base plans.

Verified November 2026. Prices and rules were checked against Microsoft Learn, Microsoft's pricing pages and the Partner Center announcements this month. Prices are US list prices, and Microsoft says its pricing pages are for marketing purposes, so your checkout or agreement is what counts.

What do I need to use Microsoft Copilot?

You need an eligible Microsoft 365 subscription, a Microsoft Entra account and, for the full experience, a Copilot license assigned to the user. Without the license, users still get Copilot Chat. With it, Copilot works inside Word, Excel, PowerPoint, Outlook and Teams and is grounded in that user's own mail, files and meetings. Everything else in this guide is detail on those three requirements.

The Copilot names, decoded

The word Copilot now covers many products, and only some are licensed together. This table sorts them out.

The Basic and Premium labels are the ones Microsoft Learn and the in-product labels use to separate the experience users get with and without the add-on, so you will see them in the apps and the admin documentation. They are not separate products you buy.

How much does Microsoft 365 Copilot cost?

The enterprise Copilot add-on lists at $30 per user per month paid yearly on an annual subscription that auto-renews, according to Microsoft's Copilot enterprise pricing page, and it requires a separate qualifying Microsoft 365 plan. Paying monthly on an annual commitment costs about 5% more, which Microsoft's billing announcement confirms for annual subscriptions with monthly billing. Copilot Business is a cheaper option for a narrow group: it lists at $21 per user per month, but only for organizations with up to 300 users on a Business plan, and it isn't available on E3, E5 or Frontline plans, per Microsoft's Partner Center announcement, and Microsoft 365 E7 bundles Copilot into its $99 price.

If you are on E3, E5 or a Frontline plan, or have more than 300 users, the Copilot Business column does not apply to you. These are list prices on top of the base plan, and Business customers have seen limited-time promotions on Copilot Business and Business bundles, so ask your partner or check the checkout price. The comparison that matters most is not $30 versus $21. It is seats you buy versus seats that get used, which the right-sizing section covers.

What you get without the license, and with it

This is the question behind most Copilot purchasing decisions. Per Microsoft Learn, the experiences differ by data grounding, depth of integration and licensing.

Two details are easy to miss. First, Copilot respects permissions: responses are scoped by what the signed-in user can already access. That is good for security and is also why oversharing becomes a Copilot problem the day you buy seats; see the governance section below. Second, users without the add-on can still do real work with Copilot Chat by uploading files or using it with open content in Outlook and Teams, so the free tier is worth rolling out before you decide who needs more.

What you need before you can buy it

Eligible base licenses

Copilot is an add-on, so every user needs a qualifying prerequisite license. Microsoft's license options page lists them. The common ones:

• Microsoft 365: E3, E5, F1 and F3, Business Basic, Business Standard, Business Premium, Microsoft 365 Apps for enterprise and for business. Microsoft 365 E7 includes Copilot.
• Office 365: E1, E3, E5 and F3.
• Standalone services: Teams Enterprise, Teams Essentials, Exchange Online, SharePoint, OneDrive for work or school, Project and Planner, and Visio plans.
• Copilot Business specifically requires Business Basic, Standard or Premium, Microsoft 365 Apps for business or Teams Essentials, and supports up to 300 licensed users per tenant.

Technical requirements

Per Microsoft's Copilot requirements:

• Users need a work or school account in Microsoft Entra ID.
• Mailbox-grounded experiences need an Exchange Online mailbox. Copilot isn't available in group mailboxes.
• Deploy Microsoft 365 Apps to users who need Copilot in desktop apps. Some features also need a OneDrive account.
• Copilot in Teams needs a Teams license. Copilot in PSTN calls also needs a Teams Phone license and a calling plan.
• Copilot isn't available with device-based licensing for Microsoft 365 Apps for enterprise.
• Allow *.cloud.microsoft and the Copilot endpoints through your network, and make sure WebSocket connections aren't blocked.
• Third-party cookies must be enabled for Copilot in Word, Excel and PowerPoint for the web.

To check one user, Microsoft provides the Copilot License Details diagnostic.

Agents, Copilot Studio and Copilot Credits

Agents are where Copilot billing stops being per user and starts being per use. The pieces:

• Copilot Credits are the common currency across eligible AI services. Since September 1, 2025 Copilot Studio agents are billed in Copilot Credits instead of messages, with no change to pack sizes or the pay-as-you-go rate.
• Included with Copilot Chat: declarative agents grounded in instructions and public websites. Other agents are pay-as-you-go.
• Included with a Copilot license: agents in Copilot Chat, Teams or SharePoint that use classic answers, generative answers or Microsoft Graph tenant grounding aren't charged when they run as the authenticated user.
• People who use your agents don't need a special license in Copilot Studio. Guests can't access Copilot Studio.

How to pay for agent usage

Newer features follow the same model. Copilot Cowork and Copilot Code (in Frontier) need a Copilot license plus an assigned usage-based billing policy and are billed by consumption. The Microsoft 365 admin center has a Copilot, Cost management dashboard where admins create spending policies, set per-user and per-policy limits, route credit requests and review consumption by user, agent and service. Spending policies can automatically cover future services, and that setting is on by default, so review existing policies. For current rates and examples, Microsoft publishes the Copilot Credits guide and the Copilot Studio licensing and billing article.

Agent 365, Security Copilot and the other Copilot products

• Microsoft Agent 365 became generally available on May 1, 2026 and is licensed per user. It helps you observe, govern and secure agents, works best with Microsoft E5 as a prerequisite, and needs at least one user with a qualifying license to turn on. It is $15 per user per month standalone and is included in Microsoft 365 E7.
• Security Copilot is independently licensed, and Microsoft began including it with E5. Rollout started November 18, 2025 for existing Security Copilot customers and expands to all E5 customers over the following months, with 30 days' notice, and billing for standalone Security Copilot stops once it is included.
• GitHub Copilot and Copilot Studio are licensed separately and don't require a Microsoft Copilot license.

Copilot and SharePoint Advanced Management

This is the licensing detail most SharePoint admins want. Per Microsoft Learn's SharePoint Advanced Management prerequisites, you get its capabilities for your Copilot deployment when any one of these is true:

• At least one user in the organization has a Copilot license assigned. That user doesn't need to be a SharePoint admin.
• Your subscription includes SharePoint Plan 1 or 2 (or Kiosk) and you buy the SharePoint Advanced Management Plan 1 add-on.
• You have Microsoft 365 E7.

The base subscription must be one of Office 365 E3, E5 or A5, Microsoft 365 E1, E3, E5 or A5, or a US government plan. Some features, such as restricted site creation by apps, need the separate Plan 1 add-on. What you get is the oversharing toolkit: data access governance reports, restricted content discovery, site access reviews, inactive-site and site-ownership policies and more. See Microsoft's SharePoint Advanced Management overview. The practical point is that one Copilot seat can unlock the governance tools for the whole tenant, which is worth knowing before you plan a pilot.

Assigning seats and right-sizing

Assign by group

Assign Copilot licenses to a security group, not to individuals, so access follows group membership and removing someone from the group reclaims the seat. Mind the group licensing limits (no nested groups, 20 groups at a time in the admin center, errors that surface later) covered in our licensing guide and Microsoft's group licensing article.

Measure who actually uses it

The Microsoft Copilot usage report is the tool for right-sizing. Per Microsoft Learn, it shows enabled users (those with a Copilot license), active users (enabled users who tried a user-initiated Copilot feature) and the active user rate, over the last 7, 28, 90 or 180 days. Data typically arrives within 48 hours. The per-user table lists everyone licensed in the past 180 days with their last activity date by app, which makes reclaiming idle seats straightforward. Only intentional actions count: opening the Copilot pane does not count, submitting a prompt does. Microsoft also points to the Copilot Dashboard in Viva Insights for readiness, adoption and impact, and to organizational messages for nudging users who haven't started. Don't use audit log data for adoption counts, because Microsoft says it isn't built for that and the numbers won't match.

Watch the removal rules

Copilot seats follow the same buying rules as other licenses. For subscriptions bought directly on a Microsoft Customer Agreement, you can remove licenses only within seven days of buying or renewing, and you can't go below the number currently assigned. Buying through a partner means asking the partner. Decide your count before the renewal date, not after.

Govern your data before you buy seats

Because Copilot reads whatever the user can already open, oversharing turns into wrong answers and exposed content the day seats go live. Fixing it is cheaper than the seats. Start with auditing "Everyone except external users", review your sharing links, and run our Copilot oversharing self-assessment. The free Smart Permissions web part shows who can access what, including unique and inherited permissions, before Copilot sees it. Microsoft also describes a secure and governed foundation (SharePoint Advanced Management and Microsoft Purview) as strongly recommended, though not required.

How many Copilot seats should you buy?

There is no formula that fits everyone, so treat this as a practical approach rather than Microsoft guidance.

1. Start with Copilot Chat, which you already have. It is included at no extra cost, so check that your network allows it and see who is already using it before you pay for anything.
2. Fix the data foundation. Clean up oversharing and label sensitive content. Use the SharePoint Advanced Management tools that one seat unlocks.
3. Buy Copilot licenses for a small pilot group. Pick people with heavy document, email and meeting loads, plus a few skeptics, and give them a defined goal. Copilot licenses are annual subscriptions, so every seat is a year-long commitment. Keep the group small.
4. Run it for 60 to 90 days and review the usage report: active user rate, last activity, and what people say they saved.
5. Reclaim idle seats, then expand to roles where usage and value are clear. Revisit at every renewal.
6. Decide on agents separately. Set spending policies and limits in Cost management before anyone builds or runs billed agents.

Why we pilot: 100 enterprise seats cost $36,000 a year at list, and because they are annual subscriptions you pay for the full term. For a subscription bought directly on a Microsoft Customer Agreement, you can generally remove seats only in the first seven days after buying or renewing. So if only 40 people are active after 90 days, you can't cut the other 60 yet. What the usage data gives you is a clear, measurable reason to renew 40 seats instead of 100, which saves $21,600 a year from the next term. A 15-seat pilot costs $5,400 a year, which is why a small pilot is far cheaper than a large rollout that disappoints.

Common Copilot licensing mistakes

• Buying seats for everyone before running a pilot, then discovering a low active user rate.
• Buying Copilot before cleaning up permissions, so it surfaces content people shouldn't see.
• Missing the seven-day window or renewal date and being stuck with unused seats for a year.
• Letting agents run on pay-as-you-go with no spending policy or limits.
• Forgetting the prerequisites: a base license, an Exchange Online mailbox and the Teams license for Teams features.
• Assuming Copilot Business works above 300 users. It is capped at 300 licensed users per tenant.
• Buying E7 for a handful of Copilot users. E7 only pays off when you deploy Copilot broadly and want the agent governance.
• Trusting old pricing. The product name, tiers and billing model have all changed in the past year.

Where to verify before you buy

• Microsoft Copilot plans and pricing (enterprise)
• What is Microsoft Copilot? (compare licenses)
• License options for Microsoft Copilot
• Microsoft Copilot requirements
• Compare Copilot in E3, E5 and E7
• Usage-based billing and cost management for Copilot Credits
• Copilot Studio licensing and billing
• Microsoft Agent 365 overview
• Microsoft Copilot usage report
• SharePoint Advanced Management prerequisites

Get Copilot-ready

The seats are the easy part. The hard part is a tenant where Copilot only finds what it should. Run the Copilot oversharing self-assessment and the free Smart Permissions report first. If you'd like help with a readiness review or a second opinion on your Copilot rollout, get in touch.
