Succession planning statistics, sourced and verified.

Every figure on this page was checked against the organization that published it, linked to the primary source wherever one exists, and dated honestly. No recycled aggregator numbers, no statistics of unknown origin.

How this page works: figures verified 2026-07-04, refreshed annually. Where a primary source is paywalled, we verified through a reputable secondary that explicitly attributes the figure, and we say so. Older canonical research (Bidwell 2011, the Stanford board survey) is dated honestly rather than passed off as new.

Citing these numbers: cite the original source we link, not us. If this compilation saved you the digging, a link here helps other people find it — and the format below is ready to paste.

Succession planning statistics: common questions

21% of organizations have a formal succession plan, another 24% run an informal one, and 56% have no plan at all, per a 2021 SHRM survey of HR professionals. At board level the figure is higher but still short of universal: 51% of directors say a written succession plan exists for their current CEO (Gartner, 2023 Board of Directors Talent Survey, 200 directors). Among nonprofits, 27% have a written executive succession plan (BoardSource, Leading with Intent, 2017).

20% of HR leaders say their organization has leaders ready now to fill critical roles, leaving 80% without confidence in their bench (DDI, Global Leadership Forecast 2025, covering 10,796 leaders across 2,014 organizations). Counted by role rather than by sentiment, internal candidates could immediately fill 49% of critical positions, even though 75% of organizations say they prefer to promote from within.

Harvard Business Review’s 2021 analysis “The High Cost of Poor Succession Planning” (Fernández-Aráoz, Nagel, Green) estimates that badly managed CEO and C-suite transitions destroy roughly $1 trillion of market value a year across the S&P 1500, and that company valuations and investor returns could run 20 to 25% higher with better succession planning.

On the published evidence, usually. Externally recruited CEOs are 84% likelier to leave within their first three years than internally promoted ones (Allgood & Farrell, reported in the HBR analysis, 2021). External hires into the same jobs command an 18 to 20% pay premium while receiving worse performance evaluations for their first two years and exiting at higher rates (Matthew Bidwell, Wharton, Administrative Science Quarterly, 2011). Modelling 17 years of outside-CEO hiring at US public companies, HBR found 39% of external hires would have outperformed a comparable internal promotion, meaning the majority would not.

Two hours a year, in the canonical Stanford GSB Rock Center and Heidrick & Struggles survey of more than 140 CEOs and directors (2010), in which 39% of respondents reported zero viable internal candidates. More recently, 30% of public-company directors say their board has no CEO successor identified and a further 10% do not know, while 58% call maintaining an internal pipeline the hardest part of CEO succession (NACD, 2024 Public Company Board Practices and Oversight Survey).

Yes. 2024 set an all-time record of 202 CEO departures across 13 major global stock indices, 43 of them by CEOs who had held the role under three years (Russell Reynolds Associates, Global CEO Turnover Index). Only 22% of those departures were part of a planned succession process, while internal promotion of incoming CEOs simultaneously reached an all-time high of 73%.
