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 costs $200K-$500K and takes 6-12 months. Use this tool to prioritize where to invest before engaging a 3PAO.
