Google Workspace vs Microsoft 365 for the enterprise: the five year cost, with switching included.

Workspace costs less than Microsoft 365 once security and add-ons are priced, but the cost of switching usually decides the outcome. Count what you use from E5, model the overlap, and size the AI line on adoption.

Is Google Workspace cheaper than Microsoft 365 for an enterprise?

Yes, on license cost, and by more than most buyers expect once the full stack is priced. In the comparisons we ran, fully loaded Microsoft 365 came in 20 to 45 percent above Workspace after security, telephony and add-ons were counted. Whether you should move is a separate question, and the cost of switching usually settles it.

The list gap is wider. Workspace Enterprise Plus lists at $30 per user per month in proposals (Google does not publish it), against $57 for E5 with Teams until June 30, 2026 and $60 from July 1, 2026. At renewal, net rates ran roughly $18 to $24 and $42 to $48, and the model below uses $22 and $45.

On these lines E5 costs $5.4M more over the term, about 25 percent above the Workspace stack. Telephony, the AI line and the months you pay for both suites during a move sit outside the table, and each is priced in its own section below.

What are the five cost lines in a suite comparison?

Price all five over the full term. Leave one out and the result tilts toward whichever vendor sells that line as an extra.

• SKU rate. The per user price of the productivity suite itself, at net effective after discount.
• Security and compliance. What E5 includes in its rate, and what the Google side buys beside the core.
• Identity and access. Entra ID P2 on the Microsoft side, and on the Google side whatever you add to reach the same controls.
• Generative AI attach. Microsoft 365 Copilot or Gemini Enterprise, priced on the users who adopt it.
• Implementation and change management. Migration services, retraining, the months you pay for both suites, and the internal program team.

Microsoft puts more into a higher rate. Google prices a lower core and sells add-ons beside it. Which ends up cheaper depends on how much of the Microsoft bundle you use and which suite you run today.

When does the Microsoft 365 E5 bundle cost less than Workspace plus add-ons?

E5 wins when you run most of what it includes. It carries endpoint detection, email protection, identity protection, SaaS app monitoring, data protection, eDiscovery, conditional access, device management and, in the version with Teams, Teams Phone inside one rate. If all of that is deployed, no set of add-ons on the Google side matches the price.

Microsoft now lists Security Copilot capabilities inside E5 as well. Workspace Enterprise Plus covers part of the list natively and prices the balance as add-ons or third party tools.

Chrome Enterprise Premium is the product Google sold as BeyondCorp Enterprise until 2024, so count it once. Our E5 security upgrade analysis works through the same trade from the Microsoft end.

How do you check what you actually use from E5?

Count what is deployed, since every E5 user is entitled to all of it. These are the places to look before any comparison:

• Defender for Endpoint. The device inventory in the Microsoft Defender portal shows how many devices are onboarded against your total fleet.
• Defender for Office 365. Check whether Safe Links and Safe Attachments policies cover all users or only a pilot group.
• Entra ID P2. In the Entra admin center, check whether risk based Conditional Access, Identity Protection and Privileged Identity Management are switched on.
• Purview. Count published sensitivity labels, active DLP policies and open eDiscovery (Premium) cases in the Purview portal.
• Intune. Enrolled devices in the Intune admin center, split by Windows, macOS, iOS and Android.
• Teams Phone. Users with a phone number assigned in the Teams admin center.

If only a third of these are live, you are funding capability you have not deployed. That is the case where the Workspace core plus targeted add-ons prices lower at renewal. The Microsoft side detail sits in the M365 license optimizer, and our E5 shelfware guide covers the reduction options.

How much does it cost to switch from Microsoft 365 to Google Workspace?

More than the license gap suggests. Implementation ran 8 to 14 percent of total cost of ownership on a Workspace migration in our comparisons, against 4 to 8 percent for carrying Microsoft forward. Migration plus retraining added 6 to 18 months of overlap, during which you pay for both suites.

We call that difference the incumbency premium. Whichever suite you run today costs less to keep than its price list implies, and the same logic protects a Google customer who is weighing a move to Microsoft.

What does the overlap do to the savings?

Take the 10,000 user model above as a hypothetical move from E5 to the Workspace stack. Assume Workspace runs for all 60 months of the term and the Microsoft seats stay paid through the overlap, because the old agreement runs to its end date.

Migration services and retraining come on top, so the real break even point falls below 12 months. A project that slips past its first year can spend the whole five year license saving before the last mailbox is migrated.

Is E5 at twice the Workspace list price a reason to switch?

A common recommendation is to set Enterprise Plus at $30 against E5 at $60 and present the halving as the business case for moving. We disagree. That comparison leaves out the security and identity add-ons the Google side needs, and it leaves out the overlap.

Add those and the gap in the model above falls to about 25 percent, which an overlap past 12 months consumes. Build the full switch model first, then put it in front of your current vendor at renewal. A fully priced alternative wins a better discount whichever suite you keep.

How does the answer change with company size?

• 500 users. Google's Business plans stop at 300 users, so the comparison is Enterprise Standard or Enterprise Plus against E3 or E5. Discounts are thin at this size, but the migration is small and short, so the license gap tends to decide.
• 10,000 users. The model above. How much of E5 you deploy and how long the overlap runs decide the outcome.
• 20,000 users and above. Discounts widen on both sides. Years of Excel models, Outlook integrations and SharePoint sites raise the migration cost, and a persona split becomes worth pricing.
• A new entity. A spinout or acquisition without an incumbent suite has no overlap to fund, so the license comparison applies almost directly.

How do Microsoft 365 Copilot and Gemini Enterprise compare on price?

They list at parity, at $30 per user per month each. At enterprise renewal we saw Copilot net at roughly $24 to $28 and Gemini Enterprise at $22 to $26. Attach, the share of active users who take a seat, ran 25 to 45 percent and 20 to 40 percent respectively.

One difference changes the comparison. Gemini in Gmail, Docs, Sheets and Meet has been part of the Workspace Business and Enterprise seat price since January 2025, so some of what Copilot charges for is already paid on the Google side. Our guide to what Gemini for Workspace includes sets out which features come with the seat.

How should you size the AI line?

Size it on measured adoption, since seat count overstates it. Say 3,500 of your 10,000 users take Copilot, a 35 percent attach, at $26 net. That costs 3,500 × $26 × 12, or $1,092,000 a year. Licensing all 10,000 users at the same rate would cost $3,120,000.

Run a paid pilot, measure active use for a quarter, and buy the next tranche on that data. The three assistant comparison covers feature differences, and our Gemini Enterprise licensing guide covers the Google editions.

Does Microsoft 365 E7 change the comparison?

Only for tenants where nearly everyone uses Copilot. E7, available since May 1, 2026, bundles E5, Copilot, Agent 365 and the Microsoft Entra Suite at $99 per user per month. E5 at $60 plus Copilot at $30 is $90, so E7 charges $9 more for Agent 365 and the Entra Suite.

At a 35 percent attach, Copilot averages $10.50 per user across the population, far below the $39 that E7 adds to every E5 seat. Our E7 guide covers when the bundle pays.

Is it cheaper to run Google Workspace and Microsoft 365 together?

It can be, for a workforce that splits cleanly by role, but it carries a cost neither vendor quotes. Roughly a quarter of enterprises now run both suites by persona, typically knowledge workers on one and frontline or specialized groups on the other. Mixed deployments paid a 10 to 20 percent integration tax.

Where does the integration tax come from?

• Identity. One directory has to be the source of truth, with provisioning and single sign on into the other suite and two sets of access policies to maintain.
• Device management. Intune and Google endpoint management each cover part of the fleet, so compliance reporting has two sources.
• Collaboration boundaries. Calendar free and busy lookups, file sharing between OneDrive and Drive, and calls between Teams and Meet all need setup and ongoing support.

Price that tax before choosing hybrid, and do not choose it because it postpones a decision. Our Microsoft 365 and Workspace feature comparison helps decide which personas belong on which suite.

Does a competing quote from the other vendor lower the price?

Yes. A documented cross vendor position lifted the discount band by 4 to 9 percentage points in our comparisons, and it pays whichever suite you keep. It needs a real quote from the other side, because account teams price the probability that you would act on it.

What will the account teams say, and how should you answer?

• Microsoft: "Workspace cannot match the E5 security stack." Answer with your consumption data: "Here is what we run from E5 today, and here is Google's quote with the add-ons we would need priced in."
• Microsoft: "The migration will cost more than you save." Say you have modeled it, and ask Microsoft to close the loaded gap at renewal.
• Google: "We will fund your migration." Ask for the amount, the free overlap months and the price hold in the order form, each with a number.
• Either side: "This price is only good until quarter end." Reply that your decision date follows your renewal timeline, and ask for the quote to hold until then.

Which contract terms should you ask for?

• A price hold for the full term. Cover every SKU and add-on, so a list price change such as Microsoft's July 2026 increase cannot reach you mid term. Our note on the Workspace price hold and uplift cap gives wording for the Google side.
• Reduction rights at each anniversary. Seat counts can then fall if a persona group shifts to the other suite.
• Transition credits in writing. The new vendor's order form should state the free or discounted months and the amounts.
• AI seats on their own schedule. Buy Copilot or Gemini Enterprise separately from the core seat count, with the right to reduce at anniversary.
• A stated renewal uplift cap. A percentage in the contract, since verbal assurances do not survive a change of account team.

What have we seen in recent Workspace and Microsoft 365 comparisons?

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. Four patterns recurred.

• The loaded gap favored Google. Microsoft 365 ran well above Workspace once the full stack was counted.
• Switching cost set the real total. Overlap months, more than the license rate, decided whether a switch paid back.
• Mixed deployments cost more than planned. Integration work appeared in neither vendor's quote.
• The competing quote paid either way. A real alternative on the table won the wider discount band whether the buyer switched or stayed.

A model built on license cost alone consistently overstates the case for moving.

What to do next

1. Count E5 consumption. Pull the Defender, Entra, Purview, Intune and Teams Phone figures and mark each component as deployed or entitlement only.
2. Segment the workforce by persona. Frontline and light users rarely need the top tier on either suite, so price them separately.
3. Model the switch with overlap. Use your real agreement end dates, migration services and retraining, and find your own break even month.
4. Size the AI line on adoption. Pilot Copilot or Gemini Enterprise, measure active use for a quarter, and buy on that number.
5. Get a real quote from the other vendor. Share the competing position with both account teams before the final quarter of the term.
6. Write the terms down. Price hold, reduction rights, transition credits and an uplift cap belong in the contract. Our Microsoft practice and Google practice can run the model with you.
