The gender pay gap is the difference in average compensation between male and female employees within an organisation. It is most commonly expressed as a percentage of male pay — for example, a gender pay gap of 12% means that, on average, women earn 12% less than men in the same organisation.

The gender pay gap is one of the most prominent metrics in the current pay transparency and pay equity agenda, and one of the primary targets of the EU Pay Transparency Directive — which comes into force progressively from 2026 and requires employers to measure, report and ultimately close unjustified pay gaps. For consulting firms operating in Europe, addressing the gender pay gap is moving rapidly from a voluntary commitment to a legal obligation.

Mean vs Median Gender Pay Gap

The gender pay gap can be calculated using either the mean (average) or the median pay of male and female employees. Both measures are commonly reported, and they tell different stories:

  • Mean gap — Reflects the full distribution including outliers. In consulting, where Partner and senior leadership pay is very high and these roles are disproportionately held by men, the mean gap tends to be larger and more sensitive to the composition of the most senior levels.
  • Median gap — The midpoint of the male and female pay distributions respectively. Less sensitive to outliers and often considered a more representative measure of the typical experience of male and female employees. See Market Median and Percentile for context on how median-based measures work.

Regulators increasingly require both measures to be reported. The EU Pay Transparency Directive specifies median-based reporting as the primary metric, with mean data also required in many reporting frameworks.

Unadjusted vs Adjusted Gender Pay Gap

A critical distinction in gender pay gap analysis is between the unadjusted (raw) gap and the adjusted gap:

  • Unadjusted gap — Compares average pay across all male and female employees regardless of role, level or line of business. This is the headline figure most commonly cited in public reporting. It reflects both genuine pay discrimination and differences in the distribution of men and women across levels and functions.
  • Adjusted gap — Controls for role, career level, line of business, geography and other legitimate pay determinants. It isolates the portion of the gap that cannot be explained by structural differences in workforce composition and is therefore most directly attributable to pay inequity. The adjusted gap is typically smaller than the unadjusted gap, but it is the more meaningful measure of pay discrimination specifically.

In consulting, the unadjusted gender pay gap is often substantially driven by the underrepresentation of women at senior levels — particularly at Partner — rather than by unequal pay for equivalent roles. Closing the gap therefore requires both pay equity work (the adjusted gap) and structural representation work (career pipeline and promotion equity). See Promotion Criteria and Internal Equity.

Gender Pay Gap and the EU Pay Transparency Directive

The EU Pay Transparency Directive introduces specific gender pay gap obligations for employers operating in EU member states. Key requirements include:

  • Mandatory reporting of gender pay gap data, with thresholds based on employer size
  • Joint pay assessments where the gender pay gap exceeds 5% and cannot be justified on objective, gender-neutral grounds
  • Proactive disclosure of pay range information to job applicants
  • Prohibition on asking candidates about salary history
  • Employee rights to information about their own pay and comparator pay levels

Full implementation timelines vary by member state and employer size, but firms with 250 or more employees face the earliest deadlines. For a comprehensive overview, see EU Pay Transparency Becomes Law in 2026.

Gender Pay Gap in Consulting Specifically

Consulting firms face a specific structural challenge in gender pay gap management. The consulting career model — with its emphasis on steep progression, high performance expectations and demanding availability norms — has historically produced career pipelines that narrow for women at the Manager-to-Partner transition. This means that even firms with genuine pay equity at each level often report material unadjusted gender pay gaps driven by the underrepresentation of women at the top of the pay distribution.

Addressing this requires firms to examine not just compensation structures but promotion criteria, career level definitions, and the design of progression pathways that support diverse talent through the senior pipeline. The job architecture underlying the firm's career framework often embeds assumptions that inadvertently disadvantage women — and reviewing these assumptions is frequently a prerequisite for sustainable gap reduction.

Measuring and Monitoring the Gender Pay Gap

Effective gender pay gap management requires:

  • Clean, consistent job architecture with clear career level definitions that enable like-for-like comparison
  • Regular pay analysis disaggregated by gender across career levels, lines of business and geography
  • Compa-ratio analysis by gender to identify within-level pay disparities — see Compa-Ratio
  • Promotion rate analysis to identify pipeline gaps before they become pay gap drivers
  • Integration of pay equity review into the annual salary review process
