Copilot License ROI 2027 Calculator
Calculate the ROI of Microsoft 365 Copilot, GitHub Copilot, or any per-seat AI productivity license. Per-seat cost times headcount versus measured productivity gain per role, with active-user-rate adjustment because not every paid seat is a heavy user.
The Copilot License Math
Microsoft 365 Copilot costs USD 30/user/month, requires a USD 12-22/user M365 Business or Enterprise license, and is a one-year minimum commitment. Total commitment for a 100-person org: USD 50K-65K/year. GitHub Copilot Business is USD 19/dev/month, Copilot Enterprise USD 39/dev/month, no minimum. The ROI math depends entirely on per-role productivity gain and active-user rate.
License ROI Formula
Annual License Cost = Seats × Price × 12
Annual Productivity Gain = Seats × Active % × Hours Saved/Month × Hourly Cost × 12
Net ROI = (Gain - Cost) / Cost × 100
Real-World Active User Rates
Microsoft 365 Copilot deployments show 35-55 percent active monthly use after six months (Forrester TEI Study Q1 2025, multiple Gartner case studies 2025). Heavy daily users are 15-25 percent of paid seats. Light or never-users are 30-45 percent. Always discount paid seats by your projected active rate — paying USD 30/month for a seat that gets used twice a month produces no ROI.
Hours Saved per Active User per Month
Per peer-reviewed studies and IDC research 2024-2025: M365 Copilot saves an average of 11 hours/month per active user (Microsoft Work Trend Index 2024) on draft generation, summarization, and meeting recaps. GitHub Copilot saves 4-12 hours/month per active developer (varies by seniority). Salesforce Einstein Copilot saves 2-6 hours/month per CRM user. Trust your team\'s baseline measurement over vendor claims — vendors quote upper-band figures.
Building the Business Case
Run a 60-90 day pilot with 20-50 seats, measure actual time saved through usage telemetry and self-report surveys, then extrapolate. Apply a realistic active-user rate (40-50 percent). Multiply by fully loaded hourly cost (USD 50-100). Compare against license cost. If net ROI is over 200 percent at the pilot level, expand to all paid roles. Under 100 percent — investigate why adoption is low before expanding.
