The plan mix on a Microsoft 365 estate moves the bill by 30% to 50%. This article walks the persona allocation math across E3, E5, and F3, the Copilot stacking rule, and the four mix shift moves that procurement and IT carry into every Enterprise Agreement renewal.
Microsoft 365 ships three core enterprise plans. E3 is the productivity baseline. E5 adds security, compliance, voice, and analytics. F3 is the frontline plan for shift, retail, manufacturing, and field staff.
List price runs roughly six to one from F3 to E5. The persona mix on a 10,000 user estate sets the floor for the whole Microsoft Enterprise Agreement.

Map each user to the lowest plan that covers the actual work. Most estates carry four to six recurring personas, and the right plan depends on security needs, desktop apps, and whether the user touches a desk at all.
E3 is the productivity core. E5 layers security, compliance, voice, and analytics on top. F3 drops the desktop apps and shrinks storage for frontline use. Microsoft publishes the full breakdown on its enterprise plans and pricing page.
What each plan carries
| Capability | F3 | E3 | E5 |
|---|---|---|---|
| Office desktop apps | Web and mobile only | Full | Full |
| OneDrive storage | 2 GB | 1 TB | 1 TB |
| Defender and Purview | Basic | Basic | Advanced |
| Teams Phone | No | Add on | Included |
| Power BI Pro | No | Add on | Included |
List price is the starting point, not the deal. The published rates anchor the negotiation, and the Enterprise Agreement discount comes off that list. Microsoft confirms the frontline tier on its frontline worker plans page.
| Plan | List per user per month | Best fit persona |
|---|---|---|
| Microsoft 365 F3 | USD 8 | Frontline, shift, deskless |
| Microsoft 365 E3 | USD 36 | Knowledge worker baseline |
| Microsoft 365 E5 | USD 57 | Security, compliance, voice, analytics |
| Microsoft 365 Copilot | USD 30 add on | E3 or E5 base required |
A persona aligned mix shift typically drops the annual list bill by 12 to 18 percent on a 10,000 user estate. After the EA discount that is around 600K to 900K USD a year on a 5M USD list bill, and it holds for the whole term.
Copilot needs a qualifying base plan. E3 and E5 qualify; F3 does not. Microsoft lists the prerequisites on the Microsoft 365 Copilot page and in the Copilot requirements documentation.
To put Copilot on a frontline user, the user first moves from F3 to E3. That is a base plan jump near 28 USD before the 30 USD Copilot add on lands. Budget the base move, not just the Copilot line.
Five levers move the number at renewal. Pull all five inside the renewal window, before the quote is built on the inflated installed base.
The standard Microsoft account team and reseller pitch is that E5 is the safe default and a deeper discount on a broad E5 base is the prize. We disagree. In roughly 30 of the 45 estates we benchmarked across 2024 and 2025, a quarter to nearly half of E5 seats never touched a single E5 only feature, so the discount sat on top of capability nobody used. A deeper percentage off an oversized, wrongly mapped baseline still overpays. The buyer side move is to map personas and right size the plan mix first, then negotiate the rate on a clean seat count.

The default E5 for everyone position is the single largest waste pattern on a 10,000 user Microsoft estate. Map the personas first and the bill drops before the discount conversation even starts.
The eight step checklist below sequences the mix review ahead of the Microsoft 365 renewal.
E5 adds advanced security and compliance, Power BI Pro, Teams Phone, audio conferencing, and premium Defender and Purview on top of E3. E3 is the productivity baseline with full Office desktop apps, Teams, Exchange, and OneDrive. The list gap is about 21 USD per user per month.
Shift workers, retail staff, manufacturing operators, field technicians, and anyone who does not need desktop Office or large OneDrive storage belong on F3. F3 includes Teams, web and mobile Office, and shift tools at about 8 USD per user per month against 36 USD for E3.
No. Microsoft 365 Copilot requires E3, E5, Business Standard, or Business Premium as the base. An F3 user moves to E3 first, which is a base plan jump near 28 USD before the 30 USD Copilot add on for any frontline pilot.

Often yes. The E5 Security and E5 Compliance add ons let you target E5 features on the personas that need them while keeping a wider E3 base. The add on path makes sense when only a quarter to a third of the estate needs full E5.
