Google Workspace vs Microsoft 365: Cost & ROI Comparison 2026

At the entry level, Google Workspace Business Starter ($6/user/month) and Microsoft 365 Business Basic ($6/user/month) are identically priced. At the mid-tier, Google Workspace Business Standard ($12/user/month) is slightly cheaper than Microsoft 365 Business Standard ($12.50/user/month). However, Microsoft 365 Business Premium ($22/user/month) includes advanced security features (Defender, Intune) that would cost significantly more to replicate with Google Workspace add-ons.

Google Workspace hidden costs: Vault (eDiscovery) requires Business Plus or above, advanced security requires Google Workspace Enterprise, and many Microsoft-compatible features require third-party add-ons. Microsoft 365 hidden costs: Advanced security requires Business Premium, Power BI requires a separate license, and some compliance features require E3/E5 plans. Both platforms have add-on costs that can significantly increase the total cost of ownership.

For businesses that primarily use email and basic collaboration, Google Workspace offers excellent value with a simpler interface. For businesses that rely on Office documents (Word, Excel, PowerPoint), need advanced security, or use Windows devices, Microsoft 365 delivers better ROI. The switching cost from one platform to the other (migration, training, workflow changes) should also factor into the decision.

The one-time migration cost for a 25-user business is typically $1,500–$3,500 for a professional migration service. Add Microsoft 365 licensing ($6–$22/user/month) and subtract your Google Workspace cost ($6–$18/user/month). For most businesses, the migration pays for itself within 6–12 months if Microsoft 365 better fits their workflow.
