Microsoft 365 License
Cost Calculator

Organizations waste 30-40% of their Microsoft 365 budget on unused or oversized licenses. Your audit tool knows where—but can’t tell you how much.
Here is a free license calculator to estimate your actual needs.

Step 1 of 5 — Company Profile
Who are we optimizing for?

Basic profile details help us determine the right plan family (Business vs. Enterprise). Your buffer percentage will be applied to calculate the recommended license count for growth and flexibility.

Current employees + contractors needing licenses
Add buffer for growth, turnover, and flexibility (typically 15-25%)

Step 2 of 5 — Workforce Mix
How do your people work?

Understanding your workforce patterns helps us map users to the most cost-effective license tiers. Desktop Office users need full applications, while web users can use lighter plans.

No dedicated PC, primarily mobile or shared devices (retail, healthcare, manufacturing)

Planning to deploy/govern AI agents (Agent 365) or need Entra Suite identity governance? This determines whether the E7 Frontier Suite bundle is cost-effective.
Step 4 of 5 — Security & Compliance
Risk, security & compliance posture

Security requirements help us decide between E3 + add-ons vs. E5, and determine how many users need advanced protection.

Who needs advanced threat protection, DLP, and enhanced security?
Step 5 of 5 — Windows & Final Notes
Windows licensing & additional considerations

Windows Enterprise features can influence whether full Microsoft 365 suites provide better value than Office-only SKUs.

What’s Missing in Traditional Audit-Only Tools?

No Financial Context for Audit Events

When Admindroid shows you 150 inactive users, that’s operationally useful. But without cost overlay, you can’t answer:
  • Which inactive licenses are E5 ($38/month) vs. E1 ($8/month)?
  • What’s the total monthly burn rate for these unused seats?
  • Which departments or managers are responsible for the largest waste?
Without dollar values, audit data remains an IT problem—not a business solution.

No Cost Attribution or Chargeback Capability

Finance teams increasingly demand license cost allocation for effective inter company recharging:
  • Department or business unit
  • Cost center or project code
  • Manager hierarchy
  • Regional report
Traditional audit tools weren’t designed for this. They track user activity, not organizational spending

Stop Guessing. Start Optimizing.

Every day without cost visibility is another day of wasted budget. Organizations with 1,000+ Microsoft 365 users find an average of $47,000 in annual savings within the first quarter.
