Copilot can grow into a significant line item quickly, and its utilization is easy to overlook. Seats were assigned in waves of enthusiasm, pilots became defaults, and the bill may have renewed since anyone checked who actually uses it.
Here is the short version. Microsoft 365 Copilot lists at $30 per user per month on top of a qualifying base license, on an annual commitment. After the July 1, 2026 base price increases, an E3 plus Copilot seat runs $69 per user per month at list. Microsoft’s own admin center tells you exactly who has a seat and who has not touched it in 30 days. Pull that report, and the gap between assigned and active is your negotiation, 60 to 90 days before your anniversary.
What does a Copilot seat actually cost?
The add-on price is only half the number. Copilot requires a qualifying base license underneath it, and those base licenses just got more expensive.
At July 2026 US list prices, a Microsoft 365 E3 user with Copilot costs $39 plus $30, so $69 per user per month, roughly $828 per year per seat. An E5 user with Copilot is $90 per month, $1,080 per year. At 1,000 assigned seats, that is $828,000 annually on E3 or $1.08 million on E5 before anyone opens the usage report.
The Copilot add-on price itself did not move on July 1. The base licenses under it did, E3 and E5 both rose, so the all-in cost of every Copilot seat went up anyway. If your Copilot estate was priced in 2025 optimism, it is now renewing into 2026 list prices.
How do you find the seats nobody uses?
Microsoft gives you the tool. The Microsoft 365 admin center includes a Copilot usage report showing enabled users versus active users, with last activity dates per app: Word, Excel, Outlook, Teams, and the rest.
The check takes an afternoon. Pull seats assigned. Pull users active in the last 30 days. The difference is money leaving the building for software nobody opens. In our experience across Microsoft estates, the assigned-versus-active gap is one of the fastest ways to surface potential savings, and it is the same discipline whether the SKU is E5 or a Copilot add-on.
Then look one level deeper than the binary. A user who ran one Copilot prompt in Teams three weeks ago holds the same $30 seat as your analyst who lives in it. Segment by depth: daily users, weekly users, occasional users, ghosts. The ghosts are reassignments. The occasionals are a conversation.
Why Copilot waste happens
Nobody bought Copilot carelessly. The waste has a pattern, and it is organizational, not technical.
Pilots became grants. The initial rollout went to a department or a level, not to demonstrated need. Enthusiasm was the criterion, and enthusiasm does not show up in the activity report.
Nobody owns the anniversary. Annual commitment terms mean seat counts generally move at renewal, not mid-term. If nobody calendars the review 60 to 90 days ahead, the count rolls forward by default and the waste compounds for another year.
The free tier keeps moving while nobody is watching. Microsoft expanded free Copilot Chat capabilities in the July 2026 packaging updates. But it also moved the walls: effective May 16, 2026, organizations with more than 2,000 seats need the paid license for Copilot Chat inside Word, Excel, PowerPoint, and OneNote. What stays free for unlicensed users at that size is the web-grounded chat in the Microsoft 365 Copilot app and Copilot in Outlook. Microsoft communicated this through Message Center posts, so many estates may not have noticed yet. Some share of your light users still lives comfortably in the free tier. Knowing exactly where its walls sit today is part of the review. That is not an argument against Copilot. It is an argument for matching the license to the user.
What to do about it, in order
First, find your anniversary date. Everything else is timed off it. A perfect analysis delivered a week after the commitment renews is worth nothing for a year.
Second, pull the usage report and segment: daily, weekly, occasional, none. Thirty days of data is enough to act on.
Third, reclaim the ghosts. Unassign seats with no activity and hold them in a pool for new requests. Demand-driven assignment beats organizational-chart assignment every time.
Fourth, move qualifying light users to the free Copilot Chat tier and see who asks for the full seat back. Check what that tier includes at your size first: above 2,000 seats, in-app chat in Word, Excel, PowerPoint, and OneNote now requires the paid license, and the free experience is the web-grounded chat plus Copilot in Outlook. The ones who ask are your real users.
Fifth, take the numbers into the anniversary conversation. Reduced counts, documented usage, and a willingness to re-expand when adoption justifies it. That is a negotiation Microsoft’s account team understands, and it works the same way as every other line on the agreement.
Where UMS fits
We have spent 25 years negotiating software agreements for enterprises and government, and the same pattern appears repeatedly: the bill follows the assignment list, not the usage. We cut a federal agency’s Microsoft 365 bill by 39 percent in two months with exactly this discipline, paying only for what was actually used.
We are paid only from the savings we find. No savings, no fee. If your Copilot anniversary lands in the next quarter, pull the usage report this week, or give us 30 minutes and we will pull the whole estate apart for you.
Frequently asked questions
How much does Microsoft 365 Copilot cost? The enterprise add-on lists at $30 per user per month on an annual commitment, on top of a qualifying base license such as Microsoft 365 E3, E5, or F3. After the July 2026 base price increases, an E3 plus Copilot seat is $69 per user per month at list, about $828 per year.
How do I see who is actually using Copilot? Microsoft publishes a Copilot usage report in the Microsoft 365 admin center. It shows enabled users versus active users and last activity per app. Comparing seats assigned to seats active in the last 30 days is the fastest waste check available.
Can we drop Copilot seats mid-term? Under annual commitment terms, seat reductions generally happen at the anniversary or renewal, not mid-term. That is why the review needs to happen 60 to 90 days before the anniversary date, while you can still act on what you find.
Did the July 2026 Microsoft price changes affect Copilot? The Copilot add-on list price did not change, but the base licenses under it did. E3 and E5 both rose, so the all-in cost of every Copilot seat went up. Microsoft also expanded free Copilot Chat capabilities across more plans.
Is Copilot Chat the same as Microsoft 365 Copilot? No. Copilot Chat is the free web-grounded chat included with eligible Microsoft 365 plans. Microsoft 365 Copilot is the $30 paid add-on that works inside Word, Excel, Outlook, Teams, and your tenant data. One 2026 change to know: since May 16, 2026, organizations with more than 2,000 seats need the paid license for Copilot Chat inside Word, Excel, PowerPoint, and OneNote. The free tier at that size is the web app chat and Copilot in Outlook. Light users who only chat may still not need the paid seat.
What is a healthy Copilot utilization rate? There is no official benchmark, and that is the point: measure your own. If a meaningful share of assigned seats shows no activity in 30 days, you are funding a pilot at production prices. Reassign or reduce at the anniversary and buy back seats when usage justifies them.
