Free: Unlimited blocks, 1 user, basic sharing (perfect for personal notes)
Plus: $10-12/user/month (annual) — unlimited workspaces, guests, API access
Team: $25/workspace/month (up to 5 members) — admin controls, version history, guest controls
Business: $120/workspace/month — advanced admin, audit logs, security features

Hidden costs: None significant. Notion is transparent. Guest access (unlimited on Plus+). Storage unlimited. API access included on Plus plan.

Confluence Pricing

Confluence uses per-user pricing with a free tier for small teams:

Free: Up to 10 users, 250MB storage, basic features
Standard: $5/user/month — 10+ users, 250GB storage, advanced features
Premium: $10/user/month — automation, advanced permissions, 250GB storage
Enterprise: Custom pricing — 100+ users, advanced security, dedicated support

Hidden costs: Storage overages ($1-5/GB beyond plan). Marketplace apps add $10-200/mo (automation, integrations). Jira integration licensing if bundled.

OneNote Pricing

OneNote is free as a standalone app or included in Microsoft 365 plans:

Free: Unlimited notebooks, sync across devices, 5GB OneDrive storage included
Standalone (no subscription): Full features with 5GB free OneDrive
Microsoft 365 Business Standard: $13/user/month — includes OneNote, Teams, Office apps, 1TB OneDrive per user
Microsoft 365 Business Premium: $18/user/month — includes everything above + advanced security

Hidden costs: OneNote itself is free. If you need Microsoft 365, you're already paying $13-18/user. Storage beyond 1TB (M365) or 5GB (free) costs $6/mo per 100GB OneDrive extra.

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
Confluence Free	$0/mo	$0/yr	$0/person (up to 10 users included)
Confluence Standard	$50/mo	$600/yr	$5/person/mo
OneNote Free	$0/mo	$0/yr	$0/person (unlimited)
M365 Business Standard	$130/mo	$1,560/yr	$13/person/mo (includes Word, Excel, Teams, email)

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
Notion Business Plan	$120/mo	$1,440/yr	$6/person/mo (single workspace, shared cost)
Confluence Standard	$100/mo	$1,200/yr	$5/person/mo
Confluence Premium	$200/mo	$2,400/yr	$10/person/mo
Confluence + 2-3 Apps	$250-350/mo	$3,000-4,200/yr	$12.50-17.50/person/mo
M365 Business Standard	$260/mo	$3,120/yr	$13/person/mo (includes Word, Excel, Teams, email)

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

Notion Advantages

Generous free tier: Covers 90% of startup use cases with unlimited blocks
Flexible pricing: Pay per-user or per-workspace — choose what works for your team
Database features: Notion doubles as a CRM + project tracker + knowledge base (no extra tools needed)
No Atlassian lock-in: Works independently, easy to export
AI features: Notion AI (writing, summarizing) is built-in on Plus plan

Confluence Advantages

Enterprise standard: Default knowledge base for teams using Jira + Bitbucket
Advanced permissions: Space-level and page-level access controls
Version history: Track changes, restore old versions (better than Notion for regulated teams)
Free tier for small teams: Up to 10 users at no cost
Integration ecosystem: 1000+ Atlassian Marketplace apps (automation, reporting, etc.)

OneNote Advantages

Completely free: Full features with no limitations on the free plan
Microsoft ecosystem: Native integration with Teams, Outlook, Office
Existing storage: Everyone on Microsoft 365 already has 1TB OneDrive per user
Offline-first: OneNote syncs but works offline (better for users in unstable connectivity)
Familiar interface: Teams already have OneNote notebooks in Teams channels (zero learning curve)

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

Cost Optimization Tips

Notion Cost Optimization

Stick with Free: Most small teams never outgrow Notion Free. 90% of features available.
Use workspace plan: If upgrading, buy Team plan ($25/workspace/month for 5 people = $5/person) instead of Plus ($10-12/person).
Audit guests: Guests in Plus/Team plans count as full users. Remove inactive guests to save money.
Consolidate databases: Use templates and linked databases to reduce workspace sprawl.

Confluence Cost Optimization

Use Free tier: If team is 10 or fewer, stay on Free plan indefinitely.
Archive old spaces: Reduce storage cost by archiving unused documentation spaces.
Automate with apps: Buy 1-2 key Marketplace apps ($15-50/mo) instead of 5+ custom integrations.
Negotiate Enterprise: For 20+ people, Enterprise custom pricing is often 30-40% cheaper than per-user Standard.

OneNote Cost Optimization

Use Free version: Full OneNote access at zero cost. Sync is unlimited.
Leverage M365 if you have it: If paying $13/user for Business Standard, OneNote is already included. No additional cost.
Archive old notebooks: OneNote doesn't have built-in archiving, but you can move old notebooks to a "Archive" section.
Monitor OneDrive storage: Free tier is 5GB per user. Monitor shared notebooks to avoid overage ($6/100GB).
