Is Microsoft 365 Copilot worth it?
Short answerIt's worth it for the people whose repeated decisions and documents it speeds up by more than the licence costs, and not for everyone else. Work out the break-even minutes per week first, then licence the roles that clear it.
Explained for every reader
Copilot is a helper that costs money every month. If it saves you more time than it costs, it's a good deal. If you never use it, it's like paying for sweets you don't eat.
A Copilot licence costs a fixed amount per person per month. Divide that by what an hour of that person's time is worth and you get the number of hours a month it has to save to pay for itself. Some people will beat that easily. Others won't open it. The smart move is to buy for the first group and keep checking.
Treat each licence as a repeated decision with an expected value. Cost is fixed per seat; value depends on active use, minutes saved per task, task frequency and the loaded cost of the role. Set a break-even threshold per persona, licence the personas that clear it with margin, and review usage monthly so idle seats move to people at their limit.

Five questions to ask first
What decision or document will it change?
Name the task. "Productivity" is not a task. "Drafting the weekly case summary" is.
How often does that happen?
Daily tasks pay back. Quarterly ones rarely do on their own.
What is an hour of that person's time worth?
Use the loaded cost (salary plus on-costs), not the salary.
Who checks the output?
If a person has to redo the work, count their time as a cost.
What will you stop paying for?
Licences that sit idle for 30 days should move to someone on the waiting list.
Where it tends to pay, and where it doesn't
Usually pays
- Roles that write, summarise or search across Microsoft 365 content every day
- Teams that run the same approval or triage decision many times a week
- People who already use Copilot Chat and hit its limits
Usually doesn't, yet
- Roles that rarely touch documents, mail or Teams
- Organisations whose files are badly permissioned (fix that first; Copilot will find everything)
- Pilots with no named task, owner or review date
Common questions
How much does Microsoft 365 Copilot cost?
Prices vary by agreement, region and currency, and Microsoft changes them. Use the price on your own agreement. The calculator on this page starts at £25 per user per month as a labelled assumption, so replace it.
How many hours does Copilot need to save to pay for itself?
Monthly price divided by the loaded hourly cost of the person. At £25 a month and £30 an hour that is 50 minutes a month, or about 12 minutes a week, per active user.
Should we buy Copilot for everyone?
Usually not at first. Licence the personas whose tasks clear the break-even with a clear margin, measure for a month, and move idle seats.
What's the difference between Copilot Chat and Microsoft 365 Copilot?
Copilot Chat is the free, web-grounded tier. Microsoft 365 Copilot is the paid licence that works over your own mail, files, meetings and chats.
How do we measure whether it's working?
Pick one task per persona, time it before and after, and track active use in the Copilot usage reports. Write the decision down with the numbers you used, so you can check it later.
