When Copilot adoption is done well, the numbers are compelling. A Forrester Total Economic Impact study commissioned by Microsoft in 2025 — based on interviews with 16 organisations and survey data from 367 decision-makers — built a composite model of enterprise Copilot deployment. The findings were significant.
Each licensed user gained approximately 9 additional productive hours per month. For a team of 50, that is the equivalent of more than two full-time employees recovered each month from repetitive, low-value tasks. Over a three-year horizon, small and medium businesses could realise up to 353% ROI with projected cost reductions of up to $656,000.
The gains were not evenly distributed across apps. Financial modelling in Excel ran 30–40% faster, document drafting in Word was 50–60% quicker, and meeting catch-up in Teams was four times faster than manual review. Go-to-market processes improved enough to drive up to a 4% increase in revenue win rates.
