Microsoft 365 Copilot ROI Calculator

A 1-year and 3-year model of Copilot's potential capacity value against license and implementation cost. Every figure follows from the assumptions you set below — it is a model, not a measured client result.

Model output, not a measured result. Potential capacity value counts every recovered hour at the loaded rate; realized value is the share you expect to turn into redeployed capacity or cashable savings. Incremental license cost is counted against your current estate only if the tier you chose is additive.

EPC Group can deliver this

Microsoft consulting since 1997. Governance and adoption engagements are scoped and priced per tenant after a discovery call — the implementation cost you entered above is yours to set.

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 is your assumption. Measure it: baseline a cohort for four to six weeks before Copilot, then measure the same cohort after. The default 2.5 is a modelling placeholder, not an EPC Group benchmark — EPC Group publishes engagement figures only where its claims register records the population and method.
Realization factor separates potential capacity value (every recovered hour at the loaded rate) from realized value (the share that becomes redeployed capacity or cashable savings). Only realized value feeds net, ROI and payback; the downside line applies 25%.
This is a model, not a measurement. Outputs are not EPC Group client results and should be read as a range: run the conservative hours figure with a low realization factor before the business case is presented.
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.

A disciplined rollout — baseline measurement, a champion network, persona-based training — is what moves hours saved from an assumption to evidence.
