Calculating Copilot ROI: what does Microsoft 365 Copilot really deliver?

The licenses are bought and the first enthusiastic users are up and running. Then comes the question every management team asks. What is this actually delivering? That question is fair. Microsoft 365 Copilot is not a small line in the budget. The gain is not a system that runs faster. It is time employees spend differently. And that time disappears from view as soon as nobody measures it.

In this article we make Copilot's return concrete. You will read which value is created and how that works per app in Word, Outlook, Excel, PowerPoint and Teams. You will see how Copilot searches across all of Microsoft 365 and shows in one overview what is happening around a customer or project. Then we substantiate the time saving, work through an example calculation and discuss the KPIs. At the end you will find a business case template you can fill in straight away.

What does Copilot really deliver?

Copilot's return consists of three types of value. They are not equally easy to measure.

Recovered time. A meeting report used to take twenty minutes and is now ready in two. A first version of a quote no longer starts with a blank document. This value is the easiest to measure. It forms the basis of almost every business case.

Quality. Documents become more complete, because the writer has energy left for the content instead of the form. Analyses are better substantiated, because adding up and filtering is no longer a hurdle. You measure this value indirectly, for example through the number of correction rounds or through customer satisfaction.

Lead time. A request sat for three days because someone still had to look at it. Now it goes out the same afternoon. Customers notice this value fastest. Yet organizations forget it most often in their calculation.

What does research say?

For the broader impact Microsoft refers to a study Forrester Consulting carried out on behalf of Microsoft. Forrester based it on customer interviews and a survey among more than two hundred companies with up to three hundred employees. Over three years the study projects a return of 132 to 353 percent. Forrester models three scenarios for this, low, medium and high, based on a risk estimate. The medium scenario comes out at 243 percent [1].

Read these figures with the right lens. This is a model-based projection for a composite example organization and not an outcome you may expect in your own situation. The study also dates from October 2024. The spread says more than the highest number. In our practice the difference between a low and a high return lies mainly in adoption and in the extent to which organizations enrich agents with their own business knowledge. That is our experience and not a conclusion from the Forrester study.

Where the value is created, app by app

Copilot does not deliver value in general. It delivers value in concrete actions, in the apps employees already use. Below we go through the five most important apps. For each app we describe what Copilot does, give a practical example and show how the Copilot Dashboard counts that action. The features come from Microsoft's documentation. The practical examples are illustrative.

Word, from blank page to substantiated draft

Copilot in Word helps with three types of work. It creates a first version based on a prompt, an outline, notes or an existing file. It rewrites selected text, adjusts the tone or makes a passage more concise. And it summarizes a document, answers questions about the content and sharpens ideas. Copilot can draw on the broader context of your work, such as files, emails and meetings [2].

In practice. A consultant writes a project proposal. In her prompt she refers to the intake report and the email exchange with the customer. Within a few minutes there is an outline with background, approach, risks and next steps. She spends her time on sharpness and pricing instead of on structure. Her colleague has to review a forty-page policy memo. He first asks for a summary and the three biggest risks. Then he reads selectively.

What it delivers. The dashboard counts drafting, rewriting and coaching a Word document as a creation action of six minutes. A summary counts as a search or summarize action of six minutes. Microsoft explicitly calls the factor for creation a rough estimate [3].

Outlook, control over the inbox

Copilot in Outlook turns long email threads into a short summary. It writes a full draft based on a short instruction and the context of the thread. With coaching the writer gets suggestions for tone, sentiment and clarity. From a thread Copilot also creates a meeting request [4]. With a paid license you can additionally ask questions in Outlook about your inbox, calendar, meetings, chats and company data, for example which unread emails are most important [5].

In practice. An account manager returns from two days of training and finds eighty new emails. She asks Copilot which messages require action from her and has the three longest discussions summarized. Within ten minutes she knows where she stands. She writes the reply to a complaint herself. Before hitting send, she lets Copilot review the tone.

What it delivers. The dashboard counts summarizing an email thread as a summarize action. Drafting, replying and coaching email counts as a creation action. Both count as six minutes [3]. Note one caveat. Microsoft reports that the measurement of email drafts and email summaries was too low between 1 June 2025 and 18 February 2026. That also affects the assisted hours in that period [3]. Keep that in mind when comparing trend lines across those months.

Excel, from data to insight

Copilot in Excel analyzes data, creates formulas and builds charts and pivot tables. You ask a question in plain language and get insights back as a chart, pivot table, summary, trend or outlier. Copilot sorts, filters and applies conditional formatting. It pulls data from other workbooks in OneDrive, SharePoint or on your computer and even sets up dashboards and planning tools from scratch [6].

By default Copilot in Excel opens in an edit mode that changes the workbook directly. In plan mode Copilot first proposes an approach that you review. In chat mode Copilot analyzes your data without changing anything in the workbook [6].

In practice. Every month a controller receives an export of two thousand rows from the accounting package. She asks Copilot for a column with the margin per product group, a pivot table per region and an overview of deviations above ten percent compared with last month. Plan mode first shows what Copilot is going to do. She checks the approach and spends the time gained on the explanation for the management team.

What it delivers. Analysis actions in Excel count as a search or summarize action. Creating formulas, formatting and cleaning data count as a creation action. Both count as six minutes [3]. Review remains necessary, certainly for figures that end up in a report or annual accounts.

PowerPoint, from document to presentation

Copilot in PowerPoint creates a presentation based on a prompt or on an existing document. With a Microsoft 365 Copilot license that can be a Word document or a pdf. Copilot summarizes a presentation, answers questions about the content and writes new text. Licensed users can apply their organization's brand style through a template from the organization asset library [7].

In practice. A project manager has a twenty-five page final report ready. In two days he presents it to the steering committee. He has Copilot turn the report into a presentation in the brand style. Then he cuts, sharpens the core message and adds his own insights. Building the slides no longer costs an afternoon.

What it delivers. Creating, translating, rewriting and adding content to a presentation count as a creation action of six minutes. Summarizing a presentation counts as a summarize action [3]. For a complete presentation six minutes quickly feels tight. That is an extra reason to do your own baseline measurement alongside the dashboard.

Teams, meetings that carry through

Copilot in Teams summarizes meetings and calls. It captures action items, lists positions per topic and shows which questions are still open. If you join a recorded or transcribed meeting at least five minutes late, Copilot offers a summary of the part you missed. Copilot in Teams requires a Microsoft 365 Copilot license [8]. In chats and channels Copilot extracts key points, action items and decisions from long threads. By default it looks back thirty days [9].

In practice. A team lead attends six meetings a week. Afterwards he asks Copilot for the decisions, the action items with owner and the topics moving to a next meeting. He posts that overview in the team channel. A colleague who was ill reads the missed meeting in five minutes. Watching half an hour of recording is no longer necessary.

What it delivers. For meetings the dashboard uses no fixed factor. It counts the duration of the summarized meeting as assisted time. A summarized one-hour meeting therefore yields one hour of assisted time [3]. As a result Teams can quickly account for a large share of the assisted hours. That does not mean someone actually saved an hour. That is why the realization percentage further on matters so much.

Overview per app

One question, everything around a customer or project

The apps deliver gains within one document or one email thread. The biggest time drain is often exactly in between. Information about a customer or project sits scattered across mailboxes, Teams chats, meeting notes, SharePoint sites and OneDrive folders. Anyone who wants an overview quickly spends half an hour searching. Copilot can take over that search work.

How it works. Copilot works with the data the user already has access to. Through Microsoft Graph that means emails, chats, calendar items, meetings and files in OneDrive and SharePoint. Through connectors Copilot also includes third-party systems such as Salesforce, ServiceNow or Confluence [10].

Copilot Search is the search function in the Microsoft 365 Copilot app. It understands plain language and searches emails, files, chats and meetings at the same time. From a search result you move straight into the chat to ask follow-up questions or finish a task [11].

With a paid license Work IQ completes the picture. Microsoft describes Work IQ as the layer that connects Copilot with your work context. That layer uses content from Microsoft 365, data from other business systems through connectors and a memory for your style and preferences. The license also includes pre-built agents such as Researcher and Analyst [12]. Anyone using only Copilot Chat has no Work IQ and gets limited capabilities for search and notebooks [13].

Example questions

These questions show how employees request an overview in one go. The names are fictitious.

What this delivers

For a customer meeting an account manager used to search in three or four sources. Now she asks one question and checks the answer in the underlying documents. The dashboard counts every question to Copilot Chat as a search or summarize action of six minutes. That factor comes from a Microsoft study among 163 knowledge workers. With Copilot they found information in files, emails and calendars six minutes faster than without [3]. For a complete customer preparation the gain can be larger. Only include that in your business case once your own measurement shows it.

Condition, your information in order

Copilot only shows information the user already has permissions for [10]. That is reassuring and a risk at the same time. A folder shared too broadly suddenly surfaces in answers.

Administrators can limit that. With Restricted Content Discovery they keep specific SharePoint sites out of organization-wide search results and Copilot, unless a user worked with them recently. With Restricted SharePoint Search they limit search and Copilot to a controlled list of sites [10].

So include cleaning up permissions in your implementation costs. A Copilot that finds the wrong information costs trust and therefore adoption.

Substantiating the time saving per employee

You do not have to estimate the time saving. Microsoft provides measurement tools.

The Copilot Dashboard. The Microsoft Copilot Dashboard in Viva Insights calculates how many hours Copilot supported employees. Every organization with a business Microsoft 365 subscription and an active Exchange Online account can use the dashboard. A paid Viva Insights license is not required. From fifty Copilot licenses you get extra features, such as benchmarks and group-level insights [3].

The so-called assisted hours consist of three categories. Summarized meetings count for their duration. Search and summarize actions count as six minutes per action. Creation actions such as writing, rewriting and coaching also count as six minutes per action. Microsoft bases those factors on research among 163 and 147 knowledge workers respectively. The dashboard always looks at the past 28 days [3].

The dashboard also translates those hours into money. By default it calculates with 72 dollars per hour, based on figures from the US Bureau of Labor Statistics. You adjust the rate and currency yourself [3]. Do that too. A consultancy with a billable rate calculates differently from a healthcare institution. The dashboard does not yet remember an adjusted rate. You set it again on every visit [3].

The usage report in the admin center. The Microsoft 365 admin center offers a usage report for Copilot. It shows how many employees have a license, how many are active and what percentage that represents. You see per app where employees use Copilot and per user when they last used Copilot. You choose a period of 7, 28, 90 or 180 days [14].

The combination of both sources gives the complete picture. The admin center shows whether people use Copilot. The dashboard shows what that delivers.

Note. Assisted hours are an estimate based on fixed factors and not a registered time record. Microsoft itself says Copilot is probably not the only cause of differences in the figures. Seasons, role changes and reorganisations also play a part [3]. So use assisted hours as a guideline and trend line, not as hard truth in annual accounts. Complement them with your own baseline measurement.

What does Copilot cost?

Start the calculation with the full costs. Microsoft offers business customers several routes.

Microsoft 365 Copilot Chat is available at no extra cost with an eligible Microsoft 365 subscription. Chat works with web data and files the user adds and includes a standard version of Copilot in Outlook [13].

The paid Microsoft 365 Copilot license adds Work IQ, as well as Copilot in Word, Excel, PowerPoint, OneNote and Teams, the pre-built agents and extensive analysis of usage and impact [13]. On the enterprise pricing page Microsoft lists 26.00 euro per user per month with annual payment, excluding VAT [13].

Microsoft 365 Copilot Business is intended for organizations up to three hundred users. The regular price is 18.20 euro per user per month with annual payment. From 1 July through 31 December 2026 a promotional price of 15.60 euro applies. That promotional price requires an annual commitment and applies only in the first year. With monthly payment the price is 21.84 euro [12]. Microsoft charges Copilot Cowork on top of the license based on usage [12][13].

Use these amounts as an illustration. The actual costs depend on your Microsoft 365 subscription, the size of the organization, contract form, term, promotional conditions and usage costs for Copilot Cowork, for example. Microsoft itself indicates that the prices shown may differ from the actual catalog price [13]. So always check the current pricing page and your own agreement.

Example ROI calculation

The costs. For the example we take sixty licenses at 26 euro per user per month. We deliberately choose the highest rate, so the calculation does not lean on a promotional price. That comes to 18,720 euro per year. In year one add 15,000 euro for setup, training and guidance and 4,000 euro for internal management. The total investment in year one is then 37,720 euro.

The return. Suppose an average active user recovers thirty minutes per working day. With two hundred working days that is one hundred hours per year per user. For sixty users together that is six thousand hours. Multiply that by an internal hourly rate of fifty euro. Then you arrive at 300,000 euro of gross recovered time.

It is not that simple. Recovered time only creates value if that time goes somewhere. That is why we work with a realization percentage. Suppose a quarter of that time demonstrably lands in work that moves the organization forward, such as more customer contact, less overtime or a project finished earlier. Then 75,000 euro remains.

The outcome. Against 37,720 euro of costs in year one stands 75,000 euro of realized value. In this fictitious example the ROI is about 99 percent. The payback period is around six months. From year two the one-off implementation costs disappear. License and management then cost 22,720 euro per year together. Add further training and adoption guidance, because those remain recurring costs.

How sensitive is the outcome?

The realization percentage is the most important dial in this calculation. It is also the dial that is debated most. The table shows what happens when you move it.

At ten percent realization the investment does not pay back in year one. So choose the percentage deliberately low. A business case that holds up at a quarter realization is more credible than a business case that only works at one hundred percent.

Which departments benefit most?

The gain is not evenly distributed. That is good news, because it gives direction to your rollout.

Sales and account management gain on preparation and follow-up. An account manager who receives an overview of all email, documents and earlier agreements around a customer before a meeting walks in better prepared. Follow-up takes minutes instead of half an hour. Outlook and search across all of Microsoft 365 deliver the most gain here.

Customer service and support gain on retrieving knowledge. An employee who no longer searches seven SharePoint sites for the right policy handles more cases per day and gives more consistent answers.

Finance and control gain on analysis and reporting. Combining, checking and explaining figures is exactly the work where Copilot in Excel takes over the boring half. The human keeps the judgment.

HR gains on everything that repeats. Think of job postings, onboarding material and answers to the same questions about leave and arrangements. The Forrester study mentions a 25 percent acceleration in onboarding new employees [1].

Management and leadership gain on overview. Meeting reports, action lists and quickly grasping long documents structurally save evening hours. Copilot in Teams and the summarize function in Word do the heavy lifting here.

Legal and compliance roles sit at the other end of the spectrum. The gain there is real but smaller, because professionals fully check every outcome. Include that honestly in your assumptions.

KPIs to measure results

A good measurement set has three layers. You need all three.

Layer 1. Adoption. How many assigned licenses are really in use? How many users return? And how does the number of habitual users compare with the number of beginners? The Copilot Dashboard divides users into four levels. A power user performs on average fifteen or more actions per week and used Copilot in at least nine of the past twelve weeks. A habitual user performs one to fourteen actions per week, with the same regularity. A novice user does use Copilot but does not reach that regularity. The remaining users fall into a residual group [3]. A license that stays unused for three months is not an investment but a cost. This is where you intervene first.

Layer 2. Impact. Here you use assisted hours, the associated value and the satisfaction score. The dashboard calculates that score from thumbs up and thumbs down. The score only appears with at least thirty responses from at least five users within 28 days. Microsoft points to a useful signal. A group with high usage and low satisfaction is trying but getting stuck. That group is a candidate for targeted guidance [3]. Complement this with a short quarterly question to users about quality and time gained. In our experience how employees feel predicts lasting adoption better than the number of clicks.

Layer 3. Business result. This layer differs per department. Think of the lead time of quotes, the number of tickets handled per FTE, the time to a first draft of a report or the number of days until a new employee works independently. Choose two per department and no more. Measure them before the rollout, so you have a baseline. Without a baseline every discussion about ROI afterwards becomes a matter of belief.

Microsoft has embedded this measurement logic in the Copilot Control System. That framework rests on three pillars, namely security and governance, management and measurement. The measurement pillar focuses on readiness and adoption, productivity impact and business value and ROI. You can add your own business figures from systems such as SAP, Salesforce or Workday. That way you place Copilot usage next to your own KPIs [15].

A simple business case template

Keep the business case to one page. This setup works in practice.

Below the table add three lines with your most important assumptions and one line with the biggest risk. That last one makes an impression in a board meeting. It shows you already know the weak spot yourself.

• Assumption 1. Active users recover thirty minutes per working day on average. We test this after three months with the dashboard and a short survey.
• Assumption 2. A quarter of that time demonstrably lands in customer contact or in less overtime.
• Assumption 3. At least seventy percent of the licenses are active weekly after three months.
• Biggest risk. Employees use Copilot only occasionally, so the time gained lags behind while the license costs continue.

The biggest pitfall is not the calculation

Most business cases fail not on the figures but on adoption. Organizations buy licenses, give one knowledge session and then expect structural results. What happens next is predictable. A small group of enthusiasts gets going. The rest use Copilot occasionally as a search function. The average time gained lags behind, while the license costs continue every month. That way a technically successful rollout can still disappoint financially.

Adoption requires structure. A one-off training helps employees get started but rarely changes their working behavior for good. Structural adoption requires examples per role, practicing with your own work, clear agreements about safe use, a network of ambassadors, recurring support and periodic measurement. Microsoft advises something similar for agents. Set up a central team or Center of Excellence with representatives from the departments, and measure and reward adoption [16].

The usage report in the admin center then shows which licenses are active, in which apps employees use Copilot and when someone last used Copilot [14]. That way you see exactly where guidance is needed.

From assistant to agent

There is a second layer that often stays unused. Most organizations start with Copilot for productivity gains. That is a fine start. In our view the greatest value only arises when you enrich agents with business knowledge, clear instructions and specific skills. An agent that knows the purchasing policy, uses your tone of voice and has access to the right system saves far more per use than a generic assistant.

Microsoft describes the same development. Agents move from helping with work to independently carrying a recurring process from start to finish. Several specialized agents can moreover collaborate on one outcome [16].

Measuring is a continuous process

That is why the business case is not a one-off calculation. Repeat the measurement after three and after six months and link usage to concrete process indicators. Do not only look at assigned licenses. Also look at the number of employees who actively return, at the apps in which they use Copilot and at demonstrable improvement in lead time, quality or capacity.

The core is simple. Licenses make possibilities available. Training, guidance, process design and measurement determine whether those possibilities deliver lasting value. That is exactly where you create the ROI in practice.

How to move forward

We help organizations with exactly that step. With the Copilot Scan we map where the opportunities for using Copilot lie within the organization. We examine how much time employees currently spend on relevant work and show how much time could potentially be saved with Copilot. You receive a substantiated baseline measurement, concrete advice and a practical follow-up path with targeted workshops and training.
