Hi Grady, Heather (she/her/elle),
Good day! Welcome to Q&A forum.
Storage Allocation in SharePoint Online
- Base Storage:
- Each SharePoint Online tenant gets 1 TB + 10 GB per licensed user (minimum 1 TB)
- Example: 100 users = 1 TB + (10 GB × 100) = 2 TB total
- Subsite (Child Page) Storage:
- No separate 10GB allocation per child page - this is a common misconception
- All subsites share the parent site's storage pool
- There's no additional charge per child page creation
- Additional Storage:
- You can purchase extra storage at $0.20/GB/month
- No "$2k per child page" charge exists - this might refer to something else
You can Purchase Additional Storage through Microsoft 365 Admin Center:
- Go to Microsoft 365 Admin Center
- Navigate to Billing → Purchase services
- Search for "SharePoint Online Additional Storage"
- Select quantity and complete purchase
