The first question we receive when an SME asks about Microsoft's artificial intelligence is always the same: how much does Microsoft 365 Copilot really cost? The short answer is that the Copilot licence price is only the tip of the iceberg. The real cost depends on the base plan you already have, the number of users, prior technical configuration and whether you need expert guidance to ensure teams actually adopt it. This article breaks down all those factors using data from Microsoft's current 2026 catalogue and gives you the indicative ranges you should have in mind before making a decision.
What is Microsoft 365 Copilot and what can it do for an SME
Microsoft 365 Copilot is the artificial intelligence assistant integrated into Microsoft's productivity applications: Word, Excel, PowerPoint, Outlook, Teams, OneNote and the Microsoft 365 enterprise chat. It uses OpenAI language models (GPT-4 and variants) connected to your organisation's data through Microsoft Graph, which means it can answer questions based on your company's emails, documents, meetings and calendars — not just generic internet knowledge.
In practice, an SME can use Copilot to draft commercial proposals from scattered notes, summarise long email threads, transcribe and analyse Teams meetings, generate presentation drafts from a text document, or spot trends in spreadsheets without knowing how to write advanced formulas. The potential is real; the challenge lies in assessing whether the licence cost is offset by the hours saved in your specific context.
Microsoft 365 Copilot Licence Price in 2026
Microsoft announced a significant change to its pricing model in January 2025: it removed the requirement to purchase a minimum of 300 licences and opened Copilot to any company with at least one eligible licence. Since then, access has become more flexible, although the per-unit cost remains significant for an SME with 20–50 employees.
| Required base plan | Base plan price (user/month, annual) | Copilot add-on (user/month, annual) | Estimated total cost per user/month |
|---|---|---|---|
| Microsoft 365 Business Standard | ~€12.50 | ~€30 | ~€42.50 |
| Microsoft 365 Business Premium | ~€22 | ~€30 | ~€52 |
| Microsoft 365 E3 (enterprise) | ~€36 | ~€30 | ~€66 |
| Microsoft 365 E5 (enterprise) | ~€57 | ~€30 | ~€87 |
Important note: the prices above are indicative, based on Microsoft's public catalogue for Europe at the start of 2026 (excluding VAT), and may vary depending on the purchasing channel (direct Microsoft, CSP or EA), the billing country and any promotions in force. Always check the up-to-date price on the official Microsoft website or with your licensing provider.
The Copilot add-on is priced at around €30 per user per month on an annual contract for the European market, which amounts to €360 per user per year. For a company of 30 people that activates Copilot for all seats, the additional expenditure on licences alone is around €10,800 per year — just for the add-on, before adding the base plan, infrastructure and adoption support.
Prerequisites: what you need before activating Copilot
This is one of the points that surprises SMEs the most: Copilot does not work with every Microsoft 365 plan. Microsoft's published requirements for 2026 are as follows:
- A Microsoft 365 Business Standard, Business Premium, E3 or E5 licence (older Office 365 licences or F1/F3 Frontline Worker plans have limited or no access).
- Entra ID (formerly Azure Active Directory) correctly configured, with synchronised users.
- Microsoft Teams activated and deployed (for meeting summary features and Copilot in Teams).
- Exchange Online active with cloud mailboxes (a hybrid Exchange environment without full migration is not sufficient).
- SharePoint Online with properly configured permissions: Copilot accesses the files to which the user has permission, so a disorganised permissions structure produces incorrect responses or exposes sensitive documents to people who should not see them.
If your company is still using older licences or has an unsanitised hybrid environment, a Copilot activation project will require prior technical remediation work that carries its own cost.
Difference between Copilot for Microsoft 365 and other Copilot versions
Microsoft has launched several products under the Copilot brand and confusion is common. The most relevant versions for an SME in 2026 are:
- Copilot (free in Bing / web): free access to the language model from the browser, without connection to corporate data. Useful for general queries, but it does not access your documents or email.
- Microsoft 365 Copilot (paid): the licence add-on analysed in this article. Integrated into Word, Excel, Outlook, Teams, etc. Accesses your organisation's data through Microsoft Graph.
- Copilot Studio: a low-code tool for building custom agents that connect to external or internal data sources. It has an independent per-message or per-capacity pricing model, separate from the M365 Copilot licence.
- GitHub Copilot: an assistant for software developers. Separately priced, not included in M365 Copilot.
When a general manager asks «I want Copilot for my company», in 90% of cases they are referring to Microsoft 365 Copilot, the add-on that activates the assistant inside the everyday productivity tools.
Factors that push the real cost beyond the licence
The add-on price is only one part of the investment. These are the additional items that typically appear in a Copilot implementation project for an SME:
1. SharePoint permissions audit and remediation
If Copilot is going to access company files, it is essential that SharePoint permissions are properly defined. In many SMEs, the situation is the opposite: folders shared with everyone, HR documents accessible to the sales team, contracts left unclassified. Cleaning this up before activating Copilot can take between 20 and 80 hours of technical work depending on the volume of documents and the complexity of the structure.
2. Training and adoption
Microsoft has learned from its own data that the usage rate of Copilot without specific training is low. Users need to know which prompts work for each application, how to iterate a response and when to trust or question the result. A Copilot adoption programme for a team of 20–30 people typically includes group workshops, role-specific usage guides and a 4–8 week support period.
3. Base infrastructure readiness
If the company does not have Exchange Online, Teams or SharePoint correctly set up, the cost of prior remediation can exceed the Copilot licence cost itself during the first year.
4. Opportunity cost of habit change
This is not a cost in euros, but it is a cost in time: during the first few weeks, teams spend hours learning to use the assistant. If the rollout is not well managed, this period extends and the return on investment takes longer to materialise.
When is it worth activating Copilot on M365 E3 or E5?
The question SME directors ask most is not how much it costs, but whether it is worth what it costs. The answer depends on the usage profile of each user. Copilot delivers the greatest return for profiles that spend many hours on document-heavy, communication and analytical tasks: executives, project managers, sales teams and administrative departments. For operational or production profiles, the return is much lower.
Studies by Microsoft and Forrester published in 2024–2025 point to savings of between 30 and 90 minutes per user per day for intensive document-heavy profiles, although these figures should be taken as a reference point, not a guarantee, and vary greatly depending on the type of work and the level of adoption achieved.
A practical rule of thumb: if the annual licence cost per user (around €360) represents less than 2% of that profile's annual salary cost, the payback threshold is low and it is worth exploring activation. If the profile generates little billable time or does non-documented manual work, the numbers do not add up.

Copilot on M365 E3 vs M365 E5: practical differences for SMEs
The E3 and E5 plans are the most common in mid-sized companies. The Copilot add-on is the same price regardless of the base plan, but the base plan determines what additional capabilities you have available:
- E3 + Copilot: full access to the assistant in Word, Excel, PowerPoint, Outlook, Teams and Loop. Without the advanced security tools, advanced voice analytics (Teams Premium) or advanced Purview included in E5.
- E5 + Copilot: adds advanced security capabilities (Defender, Purview, Entra ID P2), which are relevant if you handle sensitive data and want Copilot to operate with enhanced compliance guarantees (GDPR, NIS2, financial or healthcare sectors).
For most SMEs with 20–100 employees and no special regulatory requirements, the E3 plan with Copilot is the reasonable entry point. Upgrading to E5 makes sense when security or compliance requirements justify it independently of Copilot.
Quick comparison: Copilot M365 vs AI productivity alternatives
| Tool | Indicative price (user/month) | Integration with own data | Best for |
|---|---|---|---|
| Microsoft 365 Copilot | ~€30 (add-on on top of M365) | Yes, via Microsoft Graph | Companies already in the Microsoft ecosystem |
| Google Workspace Gemini | ~$20–30 (depending on plan) | Yes, via Google Drive/Gmail | Companies in the Google ecosystem |
| ChatGPT Enterprise | ~$30 (minimum seats) | Limited without additional connectors | General conversational use |
| Custom AI agent (RAG) | Variable depending on project | Yes, on any data source | Specific use cases outside Microsoft |
The advantage of Copilot M365 over generic tools is its native integration with the environment the company already uses. If your company lives in Teams, Outlook and SharePoint, the assistant is where the work happens — no copying and pasting between applications. The disadvantage is that if the Microsoft environment is not well organised, Copilot amplifies the disorder rather than resolving it.
How to budget for Copilot in your company: a summary of cost items
To put together a realistic budget for implementing Microsoft 365 Copilot in an SME, these are the items you should include:
- Copilot licences: number of activated users × ~€30/month × 12 months.
- M365 base plan if you do not have one yet or need to upgrade: annual differential cost per user.
- Prior technical audit (permissions, SharePoint, Exchange, Teams): between 8 and 40 hours of technical consultancy depending on the current state of the environment.
- Adoption and training programme: workshops, role-specific guides, support during the first few weeks. Variable depending on team size.
- GDPR compliance review: if Copilot is going to access customer or employee data, it is advisable to verify that the processing is recorded in the data processing register and that contracts with Microsoft as processor are up to date.
At Summum, with more than 19 years supporting SMEs through technology adoption and more than 2,000 digital transformation projects managed, the advice is always the same: start with a pilot of 10–20 users in the profiles with the highest document workload, measure the real impact over 90 days, then decide whether to extend the licence to the rest of the organisation. Avoid activating Copilot for all users at once without having validated the return.

Frequently asked questions
Can I activate Copilot for just 5 users in my company without buying licences for everyone?
Yes. Since Microsoft removed the 300-licence minimum in 2025, you can activate the Copilot add-on for whichever users you choose, provided they have an eligible base plan (Business Standard, Business Premium, E3 or E5). It is not necessary to activate it for the entire organisation, which allows you to run a controlled pilot before scaling.
Are Microsoft 365 Business Basic licences or perpetual Office 2021 licences compatible with Copilot?
No. Microsoft 365 Business Basic does not include the Office desktop applications (Word, Excel, PowerPoint) and is not compatible with the Copilot add-on for those applications. Perpetual Office licences (Office 2019, 2021) are also not eligible: Copilot requires an active Microsoft 365 subscription with the applications on the current channel version.
Does Copilot access all company files or only the user's own files?
Copilot respects Microsoft 365 permissions: it only accesses documents, emails and data to which the user who is using it has access permission. It does not have access to other users' information or to restricted documents. This makes permissions configuration critical: if a user has access to folders they should not, Copilot will too when that user makes a query.
What happens to my data when I use Copilot? Does Microsoft use it to train its models?
According to Microsoft's official documentation and the Microsoft Data Protection Addendum (DPA), customer data processed by Copilot in enterprise accounts is not used to train the underlying language models. Data is processed in accordance with the service agreement and GDPR conditions for European customers. Microsoft acts as data processor under the terms of the DPA, which you should review and document in your data processing register if you handle personal data.
