Microsoft 365 Copilot vs Google Workspace Gemini: Real AI Office Cost per Employee in 2026

Short answer: Google bundles its AI (Gemini) into Workspace's Business Standard tier and above at no separate charge, and on an annual commitment this now works out to $14/user/month for full Gemini access. Microsoft sells Copilot as an add-on to a qualifying Microsoft 365 base plan, but - critically - Microsoft also officially sells a bundled SKU (base plan + Copilot together) that is meaningfully cheaper than buying the two separately: Business Standard + Copilot bundled runs $23.50/user/month, versus $32-$35/user/month if you buy the base plan and the Copilot add-on as two separate line items. Using the correct, cheapest official Microsoft path, Google Workspace remains less expensive per employee at every size modeled here, but the gap is smaller than a naive "base plan + separate add-on" calculation would suggest.

What's actually required, and what's an add-on

Microsoft 365 Copilot is never a standalone purchase, and it is sold two ways: as a separate add-on license layered on an existing base plan, or as a bundled SKU that combines a specific base plan with Copilot at a single, lower price. Both are official, current Microsoft offerings — the bundle is simply the cheaper of the two for the same combination of features.

Google Workspace Gemini is not sold separately at all as of 2026 — the standalone Gemini Business ($20/user/month) and Gemini Enterprise ($30/user/month) add-ons Google sold through 2025 were discontinued and folded into Workspace's own plan tiers.

Pricing at a glance

Microsoft 365 (per user/month) — showing both the bundled and separate paths:

Microsoft 365 Copilot Chat is included free with eligible plans but is a lighter product than licensed Copilot — no full org-data grounding, no Teams meeting summarization.

Google Workspace (per user/month) — annual commitment vs. flexible billing:

Google's own pricing page advertises a 16% saving for the one-year commitment over the flexible plan; the figures above reflect that ratio. Compare billing cadences on like-for-like terms: the worked scenarios below use annual commitment figures throughout rather than mixing a flexible-plan number for one vendor against an annual number for the other.

Word/Docs, Excel/Sheets, PowerPoint/Slides, Outlook/Gmail, Teams/Meet — what AI does in each

Both platforms apply their AI assistant across the equivalent core apps once you're on a qualifying tier: drafting and rewriting in documents, formula help and data analysis in spreadsheets, slide generation in presentations, email drafting/summarization, and meeting transcription/summary in the video conferencing tool. Neither vendor lets you buy AI for only one app at a reduced rate — it's an all-or-nothing addition across the suite once your tier qualifies.

Worked examples — using the cheapest current official path for each vendor

10-person SMB

• Microsoft, bundled SKU: 10 × $23.50 = $235/month, or $2,820/year. (For reference, the separate-purchase path costs 10 × $32 = $320/month, $3,840/year — $1,020/year more for the identical combination — never the path to use if the bundle is available.)
• Google, annual: 10 × $14 = $140/month, or $1,680/year.
• Google is $95/month ($1,140/year) cheaper than Microsoft's own cheapest bundled path at this size.

50-person company

• Microsoft, bundled SKU: 50 × $23.50 = $1,175/month, or $14,100/year.
• Google, annual: 50 × $14 = $700/month, or $8,400/year.
• Google remains cheaper — $475/month, $5,700/year — at this size.

250-person company

• Microsoft, bundled SKU (still eligible at ≤300 users): 250 × $23.50 = $5,875/month, or $70,500/year. If the organization instead needs Enterprise-tier features requiring E3 + separate Copilot (no bundled discount found at this tier): 250 × ($36 + $30) = $16,500/month, or $198,000/year.
• Google, annual: 250 × $14 = $3,500/month, or $42,000/year.
• At 250 employees, Google is cheaper by $28,500/year (vs. Microsoft's SMB-eligible bundle) to $156,000/year (vs. Microsoft's full Enterprise path), depending entirely on which Microsoft base plan the organization actually needs.

Storage, admin, and security implications where pricing-relevant

Microsoft's higher-tier base plans (Business Premium, E3, E5) bundle progressively more advanced security that Google's equivalent tiers (Business Plus, Enterprise) also bundle at their own price points. This matters directly for cost: an organization that needs Microsoft's advanced security tier for reasons unrelated to AI will find the incremental cost of adding Copilot smaller than the full bundled price suggests, since the base-tier cost was arguably already justified — the bundled-SKU pricing shown above is still the right number to budget against, since it's what Microsoft actually charges for that combination, regardless of how you mentally allocate cost between "base" and "AI."

Total cost per employee and annual organization cost — summary table

Who pays more — and when the answer flips

Using each vendor's own cheapest currently-available official path, Google Workspace is less expensive per employee than Microsoft 365 + Copilot at every size modeled here — but the gap is roughly 40–45% (Microsoft's bundle vs. Google's Standard tier), not the 55–75% gap a naive base-plus-separate-add-on comparison would have shown. Microsoft's bundled SKU is the only fair comparison point for organizations under 300 seats; above that, or where Enterprise-specific features force an E3/E5 base plan, the gap widens substantially because no equivalent bundled discount was found at the enterprise tier. Neither platform's AI is a drop-in substitute for the other's specific capabilities — this article compares cost using each vendor's real cheapest path, not whether the two AIs do equivalent work.
