Microsoft 365 license types, every decision measures against $21
The whole plan stack reduces to one line: the E5 premium is $57 minus $36, exactly $21 per user per month, $252 a year, and every add on decision, every tier debate, and most of the Copilot math measures against it. The license count is the number Microsoft already has; the number that moves a renewal sits in the 90 day usage export.
Prepared by Redress Compliance · August 7, 2026 · Microsoft advisory. Based on 35 to 45 Microsoft 365 plan reviews run 2024 to 2025.
Executive summary
The $21 line settles the add on debate. E5 at $57 minus E3 at $36 is exactly $21 per user per month at list, and four of the six possible two add on pairs on top of E3 already cost more than E5: the rule of thumb that says you need three add ons before E5 pays is arithmetically wrong.
Spend past $21 on E3 add ons and you have assembled a more expensive E5 with four extra renewal dates.
The usage export tells the story the license count hides.
Across our reviews, 20 to 30 percent of E5 seats had triggered no E5 only service inside the 90 day window, shared device and shift roles sat on E3 because nobody wrote the rule sending them to F3, and security add ons stacked on E3 had already passed the E5 price they were bought to avoid.
The export from the admin usage reports, not the entitlement list, is the renewal file.
The frontline arithmetic is a fifth of the price. F3 lists at $8.00 against E3's $36.00, 22 percent at list and 30 to 40 percent after discount, because E3 discounts harder than F3 does, and F1 at $2.25 covers kiosk and task roles that need identity and Teams without a mailbox.
Business Premium at $22.00 looks like cheap E3 and is not: the 300 seat cap is hard, and it carries no Windows Enterprise upgrade rights, so it is not an E3 substitute at scale.
Copilot stacks, and the stack changes the tier math. Copilot at $30 sits on top of any qualifying base, which makes Copilot on E3 a $66 seat, $9 more than a full E5 seat carrying no Copilot at all, an interaction every tier decision now prices.
And one footnote worth $216,000 on 10,000 seats: from April 2025, annual term subscriptions billed monthly carry a 5 percent uplift, E3 at $36 becoming $37.80, which makes the billing cadence itself a negotiation line.
The list price map, July 2026
| Plan | List per user per month | Who it fits | What it does not give you |
|---|---|---|---|
| Microsoft 365 F1 | $2.25 | Kiosk and task roles | No Exchange mailbox, no Office apps, not even web edit |
| Microsoft 365 F3 | $8.00 | Shift, retail, shared device staff | 2 GB kiosk mailbox, web and mobile Office only |
| Business Basic / Standard / Premium | $6.00 / $12.50 / $22.00 | Under 300 seats | The hard cap, and no Windows Enterprise rights on Premium |
| Microsoft 365 E3 | $36.00 | Core knowledge workers | No Defender P2, no Defender for Office, no advanced Purview, no Teams Phone |
| Microsoft 365 E5 | $57.00 | Security, compliance, and voice roles | The $21 premium bills whether or not the user touches an E5 service |
| Copilot | $30.00, an add on | Users on a qualifying base | Stacks, never replaces: $66 on E3, $87 on E5 |
Everything with a dollar sign is published list, pre discount. Microsoft does not publish EA or CSP discount levels, and no single invented number substitutes for benchmarking your own tier.
The tenant string IDs matter for the audit: SPE_E3, SPE_E5, SPE_F1, and their kin are what your tenant actually returns, and mapping the export to them is how the placement review runs on data instead of plan names.
The E3 versus E5 decision, run as arithmetic
E5 folds in Defender for Endpoint P2 and Defender for Office P2, advanced Purview governance, Teams Phone, and Power BI Pro, capabilities that are otherwise separate add ons, and the decision is one comparison per persona: the add ons this role actually needs, priced against $21.
Four of the six two add on pairs already exceed it, which collapses the standard three add on rule of thumb, and the reverse test matters equally, the 20 to 30 percent of E5 seats triggering no E5 only service are $252 a year each of premium for entitlement nobody exercises.
The persona by persona framework sits in the E3 versus E5 versus F3 decision guide, and the security stack side of the same comparison in the security licensing guide.

The negotiation the price map feeds: the persona mix arithmetic, the placement rules, and the billing cadence lines worked on a representative estate.

Business plans run to a hard 300 seat ceiling, and Business Premium deserves the specific warning: E3 class identity and device control at $22, without Windows Enterprise E3 upgrade rights, which makes it a genuine value under the cap and a replanning event at scale.
The comparison worked in the Business versus Enterprise guide.
The frontline family is the deliberate saving: F1 for identity, Teams, and task apps, F3 adding web and mobile Office with the kiosk mailbox, and the placement rule, shift and shared device roles written to F plans by policy, is what the estates paying E3 for retail associates never wrote.

What we saw across plan reviews, 2024 to 2025
Across roughly 35 to 45 Microsoft 365 plan reviews Fredrik Filipsson ran in 2024 and 2025, the 90 day usage export kept telling the same story:
Seats with no E5 only service triggered in the window, paying $252 a year of premium each.
Security add ons on E3 that had already exceeded the E5 price they were bought to avoid.
The billing footnote closes the file: the 5 percent uplift on annual term subscriptions billed monthly, applied since April 2025, turns E3 into $37.80 and costs $216,000 a year on 10,000 seats, purely on payment cadence.
The review method is the deliverable: pull the active user export over 90 days, map every seat to its tenant string ID, test each persona against the $21 line and the F plan rule, and take the corrected mix into the renewal, where the discount then applies to a base worth discounting.
Your first five moves
- Pull the 90 day active user export, because the license count is Microsoft's number and the usage is yours.
- Test every E5 seat against E5 only service usage, the 20 to 30 percent paying $252 a year for nothing.
- Price every add on stack against the $21 line, because four of the six two add on pairs already lose.
- Write the F plan placement rule for shift and shared device roles, worth the 60 to 78 percent gap between F3 and E3.
- Check the billing cadence for the 5 percent uplift and price Copilot stacking into every tier decision. The license optimizer and the Microsoft practice run the map with you.
Frequently asked questions
What do Microsoft 365 licenses cost in 2026?
At published list per user per month: F1 $2.25, F3 $8.00, Business Basic $6.00, Standard $12.50, Premium $22.00, E3 $36.00, E5 $57.00, with Copilot a $30.00 add on stacking on any qualifying base.
All figures are pre discount, Microsoft publishes no EA or CSP discount levels, and annual term subscriptions billed monthly carry a 5 percent uplift since April 2025.
Is E3 plus add ons cheaper than E5?
The comparison is one number: the E5 premium is exactly $21.00 per user per month, and four of the six possible two add on pairs on E3 already cost more than it.
Spending past $21 on add ons assembles a more expensive E5 with extra renewal dates, so the per persona test prices the add ons each role needs against that single line.
How many E5 seats actually use E5 features?
In our 35 to 45 plan reviews, 20 to 30 percent of E5 seats had triggered no E5 only service inside a 90 day window, paying the $252 annual premium for entitlement nobody exercised.
The usage export from the admin reports, mapped to tenant string IDs, is what surfaces them, and the license count alone never does.
Is Business Premium a cheaper E3?
No, twice over: the 300 seat cap is hard, forcing growing firms to replan onto Enterprise, and Business Premium carries no Windows Enterprise E3 upgrade rights, so it is not an E3 substitute at scale.
Under the cap it is genuine value at $22 with E3 class identity and device control; at scale it is a ceiling to plan around early.
What does Copilot do to the tier decision?
It stacks rather than replaces: $30 on top of any qualifying base makes Copilot on E3 a $66 seat, $9 more than a full E5 seat with no Copilot, and $87 on E5.
Every tier decision now prices the interaction, and the Copilot population question, who gets a seat at all, runs on the same usage evidence as the tier placement.
When do frontline F plans make sense?
For shift, retail, and shared device roles that need identity, Teams, and light apps rather than the desktop suite: F3 at $8.00 is 22 percent of E3 at list and 30 to 40 percent after discount, with F1 at $2.25 for task roles needing no mailbox.
The saving arrives when the placement rule is written by policy, because without it those roles default to E3 forever.
