Copilot at work: what you get, what you pay

Microsoft’s AI assistant for small business, in plain numbers as of November 2026.

$18a user a month for the Copilot Business add-on, promo, paid yearly

$21a user a month, the add-on’s regular yearly price

300users, the cap for Microsoft’s business plans

Microsoft Copilot is Microsoft’s AI assistant for work: it drafts, summarizes and analyzes inside Word, Excel, PowerPoint, Outlook and Teams, grounded in your own email, files and meetings. For small businesses, Microsoft sells it as an add-on to Microsoft 365 or built into a business plan.

Interest is real. In the Federal Reserve Banks’ 2025 Small Business Credit Survey, 46% of small employer firms said they or their employees already use AI, and 83% of those users apply it to writing or marketing. For a business that already runs on Microsoft 365, Copilot is the obvious tool to evaluate, because it works where the documents and email already live.

This guide explains what Copilot does, what Microsoft charges as of Nov. 5, 2026, which features carry extra usage-based charges and how to roll it out without wasting seats. Prices come from Microsoft’s own pricing pages; check them before you buy, because promotions end and plans change.

What Microsoft Copilot does in each app

Microsoft describes Copilot as an assistant that combines large language models with your work data from Microsoft 365. In practice, it shows up as a chat pane and as buttons inside the apps.

• Word: drafts documents, suggests edits and summarizes long text.
• Excel: analyzes data, creates charts and points out patterns and insights.
• PowerPoint: builds outlines and draft presentations and recommends images or layouts.
• Outlook: drafts replies, summarizes long email threads and helps manage the calendar.
• Teams: recaps meetings and highlights action items from chats.

A paid Copilot license also adds what Microsoft calls Work IQ, the layer that connects your email, files, meetings and business data so answers reflect your actual work, plus pre-built agents named Researcher, Analyst and Facilitator, and the ability to use custom agents at no additional cost.

Copilot Chat vs. a paid Copilot license

Microsoft offers two levels. Copilot Chat is a web-grounded AI assistant included at no additional cost with eligible Microsoft 365 plans, along with Copilot in Outlook and the Microsoft Copilot app; custom agents built by your organization are available on a metered basis. A paid license adds Copilot in Teams, Word, Excel and PowerPoint grounded in your work data, the pre-built agents and adoption analytics.

Microsoft Copilot pricing for small business (Nov. 5, 2026)

Microsoft sells Copilot to small businesses in two ways: as the Microsoft 365 Copilot Business add-on for an existing business plan, or bundled into a plan. The business plans cover organizations with up to 300 users.

Microsoft’s footnote says the add-on discount runs from July 1 to Dec. 31, 2026, requires an annual commitment, applies to the first year only and is not available on trial subscriptions. Plans renew automatically, and Microsoft lists a seven-day cancellation window for a prorated refund once a paid subscription begins. A one-month free trial is offered and requires a credit card.

Watch the usage-based charges

Not everything is included in the license. Microsoft says everyday experiences, such as chat and Copilot in the Microsoft 365 apps, are included, while more advanced experiences are billed by usage. As of November 2026, those include Copilot Cowork, Code, Autopilot and the Work IQ APIs, paid with Copilot Credits, and Microsoft says more may be added over time.

Data protection: what Microsoft commits to

Microsoft says Copilot follows your organization’s existing Microsoft 365 security settings and permissions. With what it calls enterprise data protection, prompts and responses stay within the Microsoft 365 service boundary, are logged under your retention policies and are not used to train the underlying large language models. That matters for client files, but it also means Copilot can surface anything a user already has permission to open, so clean up shared folders first.

How to roll out Copilot in a small business

Keep the same human-review rule you would use for any AI tool. The SBA’s AI guidance tells owners to have a person review AI output and to keep sensitive information out of tools that are not approved for it. Our ChatGPT for small business guide compares OpenAI’s plans, and our cloud computing guide covers the Microsoft 365 basics underneath.

Is Microsoft Copilot worth it?

It depends on how much of your day already runs through Microsoft 365. A team that lives in Outlook, Teams meetings and Excel can test it quickly against real hours. A team that works mostly in other tools may get more from a standalone assistant. In the Fed survey, 71% of small firms using AI reported higher productivity, but the top challenge was accuracy (46%), so plan for review time in any estimate.

Common mistakes

• Buying seats for everyone at once. Start with a pilot group and expand on results.
• Skipping the permissions cleanup. Copilot can find files users technically had access to but never knew about.
• Ignoring usage-based billing. Set limits before staff try advanced features.
• Forgetting the promotion ends. Budget the regular price for year two.
• Trusting summaries blindly. Check numbers, names and commitments before they go to a client.

Key terms

• Microsoft 365 Copilot Business: Microsoft’s paid Copilot add-on for business plans of up to 300 users.
• Copilot Chat: the web-grounded AI chat included at no additional cost with eligible Microsoft 365 plans.
• Work IQ: Microsoft’s name for the layer that connects Copilot to your email, files, meetings and business data.
• Copilot Credits: the units used to pay for usage-based Copilot features.
• Agent: an AI tool that can carry out multi-step tasks, such as Microsoft’s Researcher and Analyst.

The bottom line: Microsoft Copilot makes the most sense for businesses that already run on Microsoft 365. Try the free Copilot Chat, license a small pilot group at the current price, cap usage-based features and buy more seats only when the hours saved are clear.
