How is Microsoft 365 Copilot ROI calculated?

Copilot ROI = (hours saved per user per week × 52 weeks × loaded hourly rate × number of users) − (annual Copilot licensing cost). Loaded hourly rate = (annual salary + 25-30% benefits + overhead) / 2080 working hours. EPC Group benchmark from 200+ deployments: 2-4 hours saved per knowledge worker per week with disciplined rollout.

What is the typical Microsoft 365 Copilot payback period?

4-9 months for organizations following disciplined rollout (executive alignment, champion network, persona-based training, baseline measurement). Without structured rollout, payback extends to 12-18 months or never reaches positive ROI.

Does this include Microsoft 365 E7 bundle pricing?

Yes. The calculator supports M365 E7 ($99/user/mo standard, $84.15 with CSP promo through Dec 31 2026) which bundles Copilot + Agent 365 at 15% savings vs standalone licensing.

What hours-saved assumption should we use?

Conservative: 2 hrs/week/user. Typical: 3 hrs/week/user. Aggressive: 4 hrs/week/user. EPC Group recommendation: start with 2.5 hrs/week conservative assumption for business case justification.

What is included in EPC Group implementation cost?

Implementation includes M365 E7 deployment, Copilot governance setup (oversharing remediation, Purview labels, DLP for Copilot), persona-based training, champion network design, Viva Insights instrumentation, 60-day hypercare. Typical: $200K-$450K for Standard tier per /services/copilot-governance-consulting.

Methodology Notes

Loaded hourly rate = (annual salary × 1.28) / 2080 working hours. The 1.28 multiplier covers benefits + employer taxes + overhead.
Hours saved per week from EPC Group's 200+ deployment benchmark: 2-4 hours per knowledge worker. Use 2.5 for conservative business case.
48 weeks per year accounts for PTO + holidays (vs 52 working weeks).
License tiers: Copilot Add-on = $30/user/mo on top of existing E3/E5. M365 E7 = $99/user/mo bundled. CSP Promo = $84.15/user/mo through Dec 31 2026.
Year 3 net assumes flat productivity gain and flat licensing. Productivity often compounds (Year 2-3 are higher) and licensing renegotiates downward at scale.
