Microsoft Tools & Calculators

Frequently asked questions

Are the EPC Group tools free to use?

Yes. Every calculator on /tools is 100% free — no email, no signup, no paywall. Results run client-side in your browser; nothing is submitted to a server. You can screenshot or print the output to save it.

How accurate are the ROI, cost, and sizing estimates?

The tools reflect 2026 Microsoft list prices and EPC Group's observed benchmarks from hundreds of Fortune 500 engagements since 1997. They deliver directional estimates suitable for board-level budget conversations and vendor comparisons. For contracted numbers, a scoped discovery call converts the estimate into a fixed-fee Statement of Work.

Which tool should I start with for a Copilot rollout?

Start with the M365 Copilot ROI Calculator to size the business case (payback period, 1-year and 3-year ROI). If ROI clears your hurdle, run the M365 License Optimizer to right-size the E3/E5/F-SKU mix and identify seats that don't need full Copilot. Together the two tools typically identify 15-30% licensing savings that offset Copilot cost.

What does the SharePoint Migration Cost Estimator cover?

The estimator asks about source (SharePoint 2013/2016/2019, file shares, Google Drive, Box), user count, content volume in TB, and complexity signals (custom workflows, Nintex, InfoPath). It outputs recommended tooling (ShareGate, Metalogix, Sharegate + native, or hybrid), estimated timeline in weeks, and cost range for migration services + tool licensing.

How does the Fabric F-SKU Calculator differ from Microsoft's official pricing page?

Microsoft's page shows F-SKU list prices. This calculator maps workload characteristics (users, refresh cadence, data volume, DirectQuery use, Copilot activation) to the correct F-SKU size, then compares Pay-As-You-Go vs Reserved Instance economics with an auto-suspend savings model. Typical output: recommended F-SKU tier, monthly cost, RI break-even point, and Power BI Premium coexistence notes.

Is the FedRAMP Readiness Score a substitute for a real assessment?

No. The Readiness Score is a 20-question self-assessment that maps to NIST 800-53 and FedRAMP Moderate/High controls. It surfaces the largest gaps quickly (typical output: 40-60% readiness for organizations without prior FedRAMP work). A full 3PAO assessment is priced by the assessor and takes 6-12 months. Use this tool to prioritize where to invest before engaging a 3PAO.
