The statistics presented in this report are drawn from five categories of published research: the ICF Global Coaching Study (conducted with PwC), the Manchester Inc. Executive Coaching Study, MetrixGlobal LLC, Bersin by Deloitte, and the Personnel Management Association. Each study used different methodologies (self-report surveys, 360-degree assessments, financial modeling), which accounts for the range in reported ROI figures.
Manchester Inc. measured ROI using pre- and post-coaching performance metrics across Fortune 500 organizations, arriving at 529% average return. MetrixGlobal extended that calculation by including retained talent value (the cost of replacing executives who would have left without coaching), which raised the figure to 788%. The ICF/PwC study surveyed its global membership and found a median return of 7x, with an interquartile range of 3.4x to 14.2x.
The Wheel of Intelligent Leadership provides the diagnostic framework for understanding why coaching produces measurable outcomes.
Inner core development (character, values, thinking patterns) and outer core skills (communication, team leadership, strategic thinking) must both be addressed for results to hold.
The comparison data (with coaching vs. without) is drawn from organizations that implemented structured coaching programs alongside control groups or historical benchmarks. Bersin by Deloitte measured engagement differences; BetterUp Labs tracked retention over three years; the Personnel Management Association compared training with and without coaching follow-up. These are not laboratory experiments. They are field studies conducted in working organizations, which gives the data practical relevance even as it introduces normal variability.
One pattern emerges across all five sources: coaching that includes structured measurement outperforms coaching that does not. Organizations that set baseline assessments, define outcome metrics before the engagement begins, and collect stakeholder feedback at six and twelve months see consistently stronger results. This aligns with what the MLEI (Mattone Leadership Enneagram Inventory) is designed to provide: a clear starting point from which change can be tracked.
