Real Cost Models for Different Team Sizes

5-Person Team (early-stage startup)

Tool Monthly Cost Annual Cost Notes
Notion Free $0/mo $0/yr Free tier covers most startup needs. Unlimited blocks. Invite up to 5 team members.
Notion Plus $50-60/mo $600-720/yr 5 users @ $10-12/user (if paying per-seat). OR $120/mo Team plan for 5 users.
Confluence Free $0/mo $0/yr Free up to 10 users. Good if Atlassian ecosystem needed.
Confluence Standard $25/mo $300/yr 5 users @ $5/user. Only if team exceeds 10 free users.
OneNote Free $0/mo $0/yr Unlimited. 5GB OneDrive storage (each user gets 5GB).
OneNote + M365 Business $65/mo $780/yr 5 users @ $13/user. Only if you need Office apps + Teams + Outlook.

Verdict for 5-person teams: Notion Free or OneNote Free are unbeatable at $0/mo. Confluence Free also works if under 10 users. Choose based on ecosystem: Notion (independent), Confluence (Jira users), OneNote (Microsoft users).

10-Person Team (growing SaaS/agency)

Tool Monthly Cost Annual Cost Per-Person Cost
Notion Free $0/mo $0/yr $0/person
Notion Team Plan $120/mo $1,440/yr $12/person/mo (shared workspace)
Notion Plus (10 users) $100-120/mo $1,200-1,440/yr $10-12/person/mo

Verdict for 10-person teams: If you don't already have M365 or Jira, Notion Free is unbeatable. Confluence Free is your only free option once you're 10+ people and need enterprise features. OneNote Free if already using Microsoft ecosystem.

20-Person Team (scale-up/enterprise)

Tool Monthly Cost Annual Cost Per-Person Cost
Notion Free $0/mo $0/yr $0/person
Notion Plus (20 users) $200-240/mo $2,400-2,880/yr $10-12/person/mo

Verdict for 20-person teams: Notion Free or Business Plan ($1,440/yr for entire team) is 2-3x cheaper than Confluence Standard. If already on Microsoft 365, OneNote is bundled and free. Confluence Premium at $200/mo is comparable to Notion Plus for 20 people.

Key Insights & Hidden Costs

Hidden Costs to Watch

Notion: Guests count as full members in Plus plan ($10-12/user even for read-only users). APIs on Plus plan may incur extra if high volume.
Confluence: Marketplace apps ($15-100/mo) often required for real teams (automations, custom reporting). Storage overage at $1-5/GB. Separate Jira licensing if bundled.
OneNote: Not really a "hidden cost" if free, but M365 at $13-18/user becomes mandatory if you want shared team notebooks with permission controls. Free OneNote lacks granular sharing.

When to Choose Each Platform

Choose Notion if:

  • You're a startup and need free knowledge base + CRM + project tracker in one tool
  • Team size is under 10 people and you don't need enterprise permissions
  • You want beautiful, customizable pages (marketing wikis, onboarding docs)
  • You prefer independent tools (no Atlassian/Microsoft lock-in)
  • You want AI-powered writing help (Plus plan)

Choose Confluence if:

  • You already use Jira for issue tracking (native integration saves 10+ hours/week)
  • You need advanced permissions (space-level, page-level, user groups)
  • You're in a regulated industry (version history, audit logs required)
  • Team is 10+ people and compliance/permissions matter more than cost
  • You need 1000+ Confluence Marketplace apps for automation

Choose OneNote if:

  • Your team already has Microsoft 365 subscriptions (OneNote is bundled, free)
  • You need deep Office app integration (Word, Excel, Teams, Outlook)
  • You want offline-first capability (sync when you reconnect)
  • Your team uses Teams channels (OneNote notebooks are native to Teams)
  • You need absolute free solution with no compromises on features
