Google Workspace Enterprise lists near $23 per user per month against Microsoft 365 E3 at $36 and E5 at $57, so Google is roughly 35 to 60 percent cheaper at list, but Microsoft 365 bundles security, compliance, and telephony that Google charges separately for or does not match, which closes much of the gap for regulated and Windows-centric organizations. The per-user headline favors Google, the total cost of a comparable security and compliance posture often favors Microsoft, and the right answer depends entirely on which capabilities an organization actually needs. This comparison sets out the 2026 list rates, the real feature deltas, and an explicit rule for which suite fits.
Inside This Guide
The tiers that actually compare
The first mistake buyers make is comparing the wrong tiers. Google Workspace runs Business Starter, Standard, and Plus for smaller organizations, then Enterprise Standard and Enterprise Plus for larger ones. Microsoft 365 runs Business Basic, Standard, and Premium up to 300 seats, then the enterprise E3 and E5 plans with no seat cap. A fair comparison pairs Google Workspace Enterprise Plus against Microsoft 365 E5, and Google Workspace Enterprise Standard against Microsoft 365 E3, because those pairs carry the closest feature sets.
Pairing across tiers, for example comparing Google Business Standard against Microsoft E3, produces a misleading gap because the cheaper Google tier lacks the security, compliance, and management features the Microsoft enterprise plan includes. For the Microsoft side of this in detail, see our Microsoft 365 E3, E5, and F3 comparison, and for the Google side our Google Workspace enterprise pricing breakdown.
Per-user list pricing in 2026
The list rates are public for the lower tiers and negotiated at enterprise scale, where both vendors discount against volume and term. The table shows representative 2026 monthly per-user list prices for the comparable tiers, before enterprise discounting.
| Tier pairing | Google Workspace | Microsoft 365 | List gap |
|---|---|---|---|
| Entry business | Business Starter ~$7 | Business Basic ~$6 | Roughly even |
| Mid business | Business Standard ~$14 | Business Standard ~$12.50 | Roughly even |
| Core enterprise | Enterprise Standard ~$23 | Microsoft 365 E3 ~$36 | Google ~36% cheaper |
| Top enterprise | Enterprise Plus ~$30 | Microsoft 365 E5 ~$57 | Google ~47% cheaper |
| Frontline | Frontline Starter ~$8 | Microsoft 365 F3 ~$8 | Roughly even |
At the core enterprise tier Google holds a clear list-price advantage, widening at the top tier where Microsoft 365 E5 carries advanced security and analytics. The list gap is real, but it is a starting point rather than a conclusion, because the E5 bundle folds in tools that a Google estate has to buy separately. The honest comparison is what a matched capability set costs, not what the base license costs.
Compare capability, not the base seat: Microsoft 365 E5 at $57 includes advanced threat protection, data loss prevention, eDiscovery, audit, and a cloud telephony foundation. Matching that posture on Google Workspace means Enterprise Plus at $30 plus third-party security and compliance tooling, which can erase most of the headline saving. Always price the complete posture you need on each suite, not the cheapest seat that runs email.
The security and compliance gap
Security and compliance is where the suites diverge most, and where Microsoft has invested to justify the E5 premium. Microsoft 365 E5 includes Microsoft Defender for Office 365, Purview data loss prevention and information protection, advanced eDiscovery, insider risk management, and a deep audit trail, all administered from one console. Google Workspace Enterprise Plus includes strong native controls, context-aware access, data loss prevention, and Vault for retention and eDiscovery, but its advanced security ecosystem is narrower and often supplemented with third-party tools.
For a regulated organization, the Microsoft bundle can be cheaper once the alternative is Google plus several point security products, because integration and single-vendor administration carry real operational savings. For an organization with lighter compliance needs, Google native controls are sufficient and the bundled Microsoft security is capability paid for and not used. The decision therefore tracks the compliance burden more than the email feature set.
Add-on costs that change the total
Both suites sell add-ons that move the real bill well away from the base seat, and the two most expensive in 2026 are AI assistants and telephony. Microsoft Copilot and Google Gemini for Workspace both add a per-user monthly charge on top of the base license, and at scale that add-on can rival the base seat itself. Telephony is the second: Microsoft Teams Phone and Google Voice each add a per-user charge plus calling-plan costs for organizations replacing a phone system.
| Add-on | Microsoft 365 | Google Workspace |
|---|---|---|
| AI assistant | Copilot, per-user monthly add-on | Gemini, per-user monthly add-on |
| Telephony | Teams Phone plus calling plan | Google Voice plus calling plan |
| Advanced security | Largely in E5 | Often third-party |
| Compliance / eDiscovery | Purview in E5 | Vault in Enterprise |
| Storage expansion | Per-user pooled, expandable | Per-user pooled, expandable |
The practical lesson is that the suite decision and the add-on decision should be made together. An organization that will deploy an AI assistant and cloud telephony to every user is buying a very different total than one that needs only email and documents, and the suite that looks cheaper at the base seat is not always cheaper once the add-ons it requires are priced in. Our Microsoft NCE pricing guide covers how Microsoft structures these add-ons under its current licensing model.
Side-by-side decision matrix
| Factor | Microsoft 365 | Google Workspace |
|---|---|---|
| Core enterprise list price | Higher (E3 ~$36, E5 ~$57) | Lower (~$23 to $30) |
| Desktop apps | Full Office desktop | Web-first, lighter desktop |
| Security and compliance | Deep, bundled in E5 | Strong native, often supplemented |
| Windows and AD integration | Native, deep | Workable, less tight |
| Collaboration model | Teams-centric | Docs and Meet-centric |
| AI assistant | Copilot add-on | Gemini add-on |
| Best for | Regulated, Windows-centric estates | Cost-led, web-first, cloud-native estates |
Three-year cost on 5,000 users
The total over a realistic term shows how the headline gap narrows once posture is matched. The model takes 5,000 users needing an enterprise security and compliance posture, comparing Microsoft 365 E5 against Google Workspace Enterprise Plus plus the third-party security tooling needed to match it.
| Cost element | Microsoft 365 E5 (3 yr) | Google Workspace + tooling (3 yr) |
|---|---|---|
| Base license | $10,260,000 | $5,400,000 |
| Added security / compliance | Included | $1,800,000 to $3,000,000 |
| Telephony foundation | Included base, plans extra | Add-on plus plans |
| Admin and integration effort | Lower, single vendor | Higher, multi-vendor |
| Three-year total (matched posture) | ~$10.3M plus plans | ~$7.2M to $8.4M plus tooling |
Even with matched security tooling Google generally remains cheaper for this profile, but the gap narrows from the headline 47 percent to roughly 20 to 30 percent once compliance parity and multi-vendor administration are priced. For an organization with lighter compliance needs the Google advantage is larger, and for one already standardized on Windows, Active Directory, and Teams the Microsoft integration can close the remaining gap. The cloud contracts guide sets out how to model this fully.
The verdict: choose which when
Choose Microsoft 365 when the organization is Windows-centric, depends on full Office desktop applications, carries a heavy compliance burden that the E5 bundle satisfies, or is already invested in Teams and Active Directory. The higher list price buys a deep, single-vendor security and compliance posture that is often cheaper than assembling the equivalent from Google plus third-party tools.
Choose Google Workspace when the organization is cost-led, web-first, or cloud-native, has lighter compliance requirements, and values the simpler administration and lower base price. The list-price advantage is real and durable for these profiles, and the native security controls are sufficient without the Microsoft bundle, so the saving holds even at enterprise scale.
The practical rule: Define the security and compliance posture you must have, then price that exact posture on each suite. If matching Microsoft E5 means Google plus several security products, model the full stack, because the integration and single-vendor administration often make Microsoft competitive despite the higher seat. If your compliance needs are light, Google wins on price and stays won.
Negotiating either suite
Both vendors discount hard at enterprise scale, and the levers differ. Microsoft negotiates on the Enterprise Agreement or its current cloud agreements, with discount tied to commitment level, term, and the mix of E3, E5, and add-ons. Google negotiates on committed user count and term, and is frequently aggressive on price when displacing Microsoft, which makes a credible Google alternative one of the strongest tools in a Microsoft renewal and vice versa.
Our advisors negotiate both suites from the buyer side, with no reseller relationship, so the recommendation follows your capability needs rather than a margin. Start with the Microsoft 365 versus Office 365 primer, the Microsoft practice, and the Google Cloud practice for engagement help.
Migration and switching cost
The list-price comparison assumes a clean choice, but most enterprises are already on one suite and weighing a move, so the switching cost belongs in the decision. Migrating an established estate carries four real costs: data migration of mail, files, and calendars, retraining thousands of users on new applications, rebuilding integrations and automation that depend on the incumbent, and a period of parallel running where both suites are paid at once. For a large organization these can total millions and take many months, which means a cheaper destination suite only wins once the recurring saving clears the one-time cost over the planning horizon.
The user-retraining cost is the one most often underestimated. Moving a Microsoft-trained workforce to Google Docs and Sheets, or the reverse, carries a productivity dip and a support burden that lasts well beyond the technical cutover. Power users who depend on advanced spreadsheet features, macros, or deep Office integration feel the change most, and their workflows are the ones most likely to break. A pilot with a representative cross-section of the workforce is the only reliable way to size this before committing, and it routinely reveals dependencies that a paper comparison misses.
Integration depth is the second hidden switching cost. An estate that has built line-of-business processes on the incumbent suite, from document workflows to identity and single sign-on, carries that engineering forward to any new platform. The more an organization has invested in one suite, the higher the wall to leave it, which is precisely why both vendors price aggressively to win a net-new estate and far less aggressively to retain a captive one. Understanding where you sit on that curve is the difference between a credible threat to switch and an empty one.
Because of these costs, the practical pattern for most large organizations is not a wholesale switch but a disciplined renewal. Use a credible, fully-modeled alternative to reset the incumbent price rather than to actually migrate, unless the saving is large enough and durable enough to clear the full switching cost. That posture captures most of the price benefit of competition without absorbing the disruption, and it is the approach our advisors run in the majority of suite renewals.
