The licence price is the comparison. The switching cost is the decision.
The productivity suite decision rests on five cost lines: the SKU rate, the security and compliance entitlement, identity and access, the generative AI attach, and the implementation and change management commitment across the term. Microsoft bundles more into a higher rate; Google prices a lower core with add ons beside it. Which is cheaper depends on how much of the bundle you actually consume, and on which suite you are already standing in.

Executive summary
Fully loaded Microsoft 365 ran 20 to 45 percent above Workspace once security, telephony, and add ons were counted.
The list gap is wide before that: Workspace Enterprise Plus at 30 USD per user per month against Microsoft 365 E5 at 57 USD, narrowing at enterprise renewal to roughly 18 to 24 against 42 to 48 USD net effective.
At 10,000 knowledge workers the five year models land at 28M to 36M USD for Workspace against 52M to 64M for E5. That gap is real and it is not the whole answer.
The E5 bundle only wins where you consume the full security stack. Microsoft 365 E5 bundles Defender, Purview, Entra ID Premium P2, and Intune, while Workspace Enterprise Plus prices Chrome Enterprise Premium, BeyondCorp Enterprise, and SaaS posture management separately as add ons.
An enterprise that genuinely runs the whole Microsoft security stack is buying it at bundle economics; an enterprise consuming a subset is paying for capability it has not deployed, and the Workspace plus add on stack prices lower at renewal in exactly that case.
Switching cost, not licence price, set the real total. Migration plus retraining added 6 to 18 months of overlap, and implementation ran 8 to 14 percent of TCO on a Workspace migration against 4 to 8 percent for a Microsoft carryover.
That asymmetry is the incumbency premium: the suite you already run is cheaper to keep than its rate card suggests, which is why a comparison that models licence cost alone consistently overstates the case for moving.
The AI line prices at parity, and a documented cross vendor position lifts the discount band 4 to 9 points.
Copilot and Gemini Enterprise both list at 30 USD per user per month, netting to roughly 24 to 28 and 22 to 26 at enterprise renewal, with attach rates of 25 to 45 and 20 to 40 percent of the active user community respectively.
A quarter of enterprises now run a hybrid deployment by persona, and mixed estates paid a 10 to 20 percent integration tax neither vendor surfaced in the quote.
Five year TCO at 10,000 knowledge workers
| Cost line | Workspace Enterprise Plus | Microsoft 365 E5 |
|---|---|---|
| Productivity SKU at net effective | 13.2M USD (22 USD net) | 27.0M USD (45 USD net) |
| Security and compliance add ons | 6.6M USD (11 USD net) | 0, bundled in E5 |
| Identity and access management | 1.8M USD (3 USD net) | 0, bundled in E5 |
| Implementation and change | 8 to 14 percent of TCO | 4 to 8 percent carryover |
| Five year total | 28M to 36M USD | 52M to 64M USD |
The bundle is the whole argument, and it cuts both ways depending on consumption.
Microsoft 365 E5 carries endpoint detection, email protection, identity protection, SaaS posture management, information protection, data loss prevention, eDiscovery, conditional access, and device management inside one rate.
Workspace Enterprise Plus covers a subset natively and prices the balance as add ons or third party tools.
An enterprise consuming the full Microsoft stack buys it at bundle economics that no add on assembly matches; an enterprise consuming a third of it is funding capability it never deployed, and that is the estate where the Workspace stack prices lower at renewal.
Count what you actually run before comparing rate cards. The Microsoft side detail sits in the M365 license optimizer.
The generative AI attach, priced at parity
| Dimension | Microsoft 365 Copilot | Workspace Gemini Enterprise |
|---|---|---|
| List rate per user per month | 30 USD | 30 USD |
| Net effective at enterprise renewal | 24 to 28 USD | 22 to 26 USD |
| Typical attach to active users | 25 to 45 percent | 20 to 40 percent |

Get the white paper →Switching cost, hybrid estates, and the competitive narrative
Switching cost is where the licence comparison stops being decisive.
A Workspace migration ran 8 to 14 percent of total cost of ownership in our file against a 4 to 8 percent carryover for staying on Microsoft, and migration plus retraining added six to eighteen months of overlap during which both estates are effectively funded.
That overlap is the incumbency premium, and it means the suite you already run is cheaper to keep than its rate card implies, which is exactly why a model built on licence cost alone consistently overstates the case for moving.
Hybrid deployment is now common rather than exotic, with roughly a quarter of enterprises running both suites split by user persona, typically knowledge workers on one and frontline or specialised populations on the other.
It is a defensible answer to a genuinely split workforce and it carries a cost neither vendor puts in a quote: mixed estates paid a 10 to 20 percent integration tax across identity, device management, and collaboration boundaries.
Price that tax explicitly before choosing hybrid on the grounds that it avoids a decision.
The competitive narrative is the one lever that pays regardless of the outcome, because a documented cross vendor position lifted the discount band by four to nine percentage points and costs nothing but the work of producing a real quote from the other side.

What we saw across productivity suite comparisons, 2024 to 2025
Across roughly 25 to 35 productivity suite comparisons we ran between 2024 and 2025, the headline per seat price decided far less than buyers expected, because the price lists look close until the full stack is in scope:
How far fully loaded Microsoft 365 ran above Workspace once security, telephony, and add ons were counted rather than compared at SKU level.
The cost mixed estates carried across identity, device management, and collaboration boundaries, which appeared in neither vendor's quote.
Three patterns recurred: fully loaded Microsoft 365 running 20 to 45 percent above Workspace once the full stack was in scope, switching cost rather than licence price setting the real total with six to eighteen months of migration and retraining overlap.
And mixed estates paying a 10 to 20 percent integration tax neither vendor surfaced.
The buyer side move is to count what you actually consume from the E5 bundle, model the switching cost honestly against the incumbency premium, price the AI attach against measured adoption rather than seat count.
And put a documented competitive position on the table because it lifts the discount band four to nine points whichever suite you keep.
Your first five moves
- Count what you actually consume from the E5 security bundle, because the bundle only wins on economics where the full stack is genuinely deployed rather than entitled.
- Model the switching cost, not just the licence delta, at 8 to 14 percent of TCO for a migration against 4 to 8 percent carryover, plus six to eighteen months of overlap.
- Segment the workforce by persona before pricing anything, since the cheapest estate is rarely uniform and the frontline population rarely needs the top tier.
- Price the AI attach against measured adoption, at 25 to 45 percent for Copilot and 20 to 40 percent for Gemini Enterprise, rather than against the full seat count.
- Put a documented competitive position on the table, which lifted the discount band four to nine points, and price the hybrid integration tax before choosing hybrid. The Microsoft practice and the Google practice run the model with you.
Frequently asked questions
Which suite is cheaper, Workspace or Microsoft 365?
On loaded cost, Workspace, by 20 to 45 percent once security, telephony, and add ons are counted, and at 10,000 users the five year models land at 28M to 36M against 52M to 64M USD.
But switching cost rather than licence price sets the real total, so the answer depends heavily on which suite you already run and how much of the E5 bundle you consume.
When does the Microsoft 365 E5 bundle actually win?
When you consume the full stack. E5 bundles Defender, Purview, Entra ID Premium P2, and Intune, which is genuine bundle economics for an enterprise running all of it.
An enterprise consuming a subset is funding capability it never deployed, and in that case the Workspace core plus targeted add ons prices lower at enterprise renewal.
How much does switching actually cost?
Implementation ran 8 to 14 percent of total cost of ownership on a Workspace migration against 4 to 8 percent for a Microsoft carryover, and migration plus retraining added six to eighteen months of overlap during which both estates are effectively funded.
That overlap is the incumbency premium and it is what a licence only comparison leaves out.
How do Copilot and Gemini Enterprise compare on price?
They list at parity, 30 USD per user per month each, netting to roughly 24 to 28 for Copilot and 22 to 26 for Gemini Enterprise at enterprise renewal.
Attach rates differ modestly at 25 to 45 percent of active users for Copilot against 20 to 40 percent for Gemini, and both should be priced against measured adoption rather than headcount.
Is running both suites a reasonable answer?
For a genuinely split workforce, yes, and roughly a quarter of enterprises now do it by persona. It carries a cost neither vendor quotes: mixed estates paid a 10 to 20 percent integration tax across identity, device management, and collaboration boundaries.
Price that explicitly rather than choosing hybrid because it postpones a decision.
Does a cross vendor RFP actually change the price?
Yes. A documented competitive narrative across both vendors lifted the discount band by four to nine percentage points in our file, and it pays whichever suite you end up keeping.
The requirement is a real quote from the other side rather than a mention, because the account teams price the probability that you would act on it.
What decides the comparison if not the rate card?
Four things: how much of the security bundle you genuinely consume, the switching cost against the incumbency premium, the AI attach priced on measured adoption, and workforce persona segmentation so the whole population is not sitting on the top tier.
The rate card is where the comparison starts and almost never where it ends.
