What's the average productivity gain with Copilot?

Based on our deployments and Microsoft studies, active users save 20 to 40 minutes per day on administrative tasks (emails, summaries, meeting prep, writing). Over a year, this represents 8-15% recovered productivity on these tasks.

How do you calculate Copilot ROI for my enterprise?

Formula: ROI = (Total gain − Total cost) / Total cost. In detail: Total gain = Time saved per day × Loaded hourly cost × Number of active users × 220 working days. Total cost = Annual license cost + Adoption program cost. The critical point: the calculation is based on ACTIVE users, not licenses purchased.

Is an adoption program cost really justified by the ROI?

In the majority of our deployments, yes. A program typically costs 10-20% of annual license cost and multiplies real usage by 3-5x. In those conditions, generated gains far exceed adoption investment. Conversely, underused licenses mechanically produce negative ROI.

Which job functions have the best ROI with Copilot?

Top ROI: executive assistants, HR/finance/legal functions, managers and middle management, sales teams. These populations have lots of writing, analysis, and synthesis tasks. Field or highly specialized jobs generally have lower ROI.

Are there hidden costs to anticipate?

Yes, three main ones: (1) license prerequisites (M365 E3/E5) if not already in place, (2) data preparation (Purview tagging, SharePoint permissions) for Copilot to access data correctly, (3) adoption program cost. The 3rd is the most underestimated — and determines final ROI.

Step 1 of 5

How many users would be in scope?

Total population that could be licensed — not just early adopters.

Estimates use Microsoft 2025/2026 benchmarks and Tomorrow Solutions deployment data. Final ROI depends on your role mix, governance maturity, and program quality.

Frequently Asked Questions

Break-even is typically reached between 6 and 12 months, provided real usage exceeds 30-40% of the licensed population. Without a structured adoption program, this threshold is rarely reached: a significant share of licenses remains underused.
