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.

The 4-step ROI calculation method

This is the exact method we use with CFOs, CIOs and HR leaders to build the Copilot business case.

Identify your gain per active user

Not "potential" time saved. REAL time saved, measured through user surveys and task time tracking. Benchmark: 20-40 min/day depending on role.

Formula

Annual gain / user = Min saved/day × 220 working days × Loaded hourly cost / 60

Estimate your REAL adoption rate (not licenses)

The critical mistake: calculating ROI on licenses deployed, not users actively using. Without program: 3-10%. With a structured adoption approach: 60-85%.

Formula

Active users = Total licenses × Adoption rate

See how our Copilot training program drives adoption rates

Account for ALL costs

Licenses + prerequisite M365 upgrades + data preparation (Purview, permissions, governance) + adoption program + change management. The adoption program is typically 10-20% of license cost.

Formula

Total cost = Licenses + Prerequisites + Data prep + Adoption program

Data prep & governance: see our AI governance framework

Compute ROI and payback

Simple and honest. If ROI is negative, the adoption program was typically underinvested. If strongly positive, scale to more populations.

Formula

ROI = (Total gain − Total cost) / Total cost • Payback (months) = Total cost / Monthly gain

Worked example

1,000 licensed users · mid-market enterprise

Without adoption program

Active users (3.3%): 33
Annual gain per active user: ~5 000 €
Total gain: 165 000 €
License cost (1,000 × €337): 337 000 €
ROI: −51%

With adoption program

Active users (65%): 650
Annual gain per active user: ~5 000 €
Total gain: 3 250 000 €
License + adoption cost: 395 000 €
ROI: +723%

Illustrative numbers based on average benchmarks. Your ROI depends on loaded hourly cost, target populations 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.
