We're evaluating a move from a mix of Notion and GitHub wikis to a centralized Atlassian stack, and Confluence is the main contender. The advertised pricing seems straightforward, but I've learned the hard way that the real cost for a 100-person engineering and product org is rarely just `users * per-user fee`.
The sticker price on Atlassian's site for Confluence Premium is $5.75 per user/month for 100 users on an annual plan. That's $6,900 per year. But that assumes a perfect 1:1 license-to-human ratio, which we've never achieved with any per-seat SaaS.
My immediate questions are:
* **Inactive Users:** How do you handle contractors, interns, or departed employees whose accounts you might keep for audit or knowledge continuity? With 100 licenses, you're paying for that "seat" even if it's archived. A 5% churn buffer adds ~$345/year.
* **Service Accounts:** Do you need bot accounts for CI/CD to post deployment reports or documentation updates? That's another seat.
* **Feature Parity:** The Premium tier is basically mandatory for any serious use (unlimited storage, audit logs). The Standard tier's 250 GB storage ceiling is a non-starter for a 100-user org with attachments. So the "real" starting point is the Premium tier price.
Beyond the base license, the operational costs spike in other areas:
* **Backup & Compliance:** If you need a third-party backup solution (like for point-in-time recovery beyond Atlassian's 90-day retention), that's an additional annual subscription.
* **Apps & Integrations:** The native Jira integration is solid, but diagramming (like draw.io), advanced templating, or publishing workflows often lead to paid Marketplace apps. These are usually priced per user as well.
A rough, pessimistic first-year cost model for 100 users might look like this:
```text
Base Cost (105 seats, 5% buffer):
105 users * $5.75/month * 12 months = $7,245
Estimated Add-ons:
Diagramming plugin (per user, annual): $500
Backup solution (annual flat fee): $800
Advanced PDF export plugin: $300
-------------------------------------------
Total Year 1 Estimate: $8,845
```
That's ~28% above the naive sticker price. The productivity justification has to cover that, not the $6,900 figure.
I'm keen to hear from teams who've gone through this:
* What was your actual license count versus headcount?
* Did you need to add significant paid apps to make it viable for engineering documentation?
* Are the automation features in Premium (like auto-archiving pages) robust enough to reduce maintenance overhead?

You're right, the real cost is never users * fee. Your 5% churn buffer is optimistic. Real numbers are closer to 10-15% for contractors and turnover. And don't forget the admin overhead of constantly deactivating and reactivating seats.
But the bigger question is why pay per seat at all? You're already using Notion and GitHub wikis. Confluence just adds another bill and another silo.
Consider a wiki that doesn't charge for inactive accounts or bots. A self-hosted option like Wiki.js or Outline gives you control. Your CI/CD bot account is free. Your archived user is just a row in your own database.
You'll spend maybe $50/month on a VM and your time. That's a fraction of the cost, even with your own labor.

You've hit on the critical flaw in the per-seat model, which is that it's priced for a theoretical headcount that doesn't match your dynamic access list. Your 5% buffer is a good start, but in my procurement work, I've seen that figure consistently underestimate the true "ghost seat" cost.
You also mentioned the mandatory upgrade to Premium. That's a classic vendor move, where the advertised entry tier lacks the core features needed for actual business use, pushing you into a higher bracket. The real comparison isn't Standard vs. Premium, it's whether the total cost of Premium plus your 10-15% buffer of inactive and bot accounts still provides value over your current mix.
For a 100-user org, I'd budget for 115-120 licenses to account for churn and automation, which brings your real annual cost closer to $8,000. Have you factored in the cost of migrating from your current Notion and GitHub wikis into that total ownership figure?
