Pay Equity Audit

A systematic analysis of employee compensation to identify unexplained pay differences by gender, race, or other protected characteristics — increasingly common as pay transparency laws spread.

A pay equity audit (also called a compensation equity analysis or pay equity study) is a structured, statistical review of an organization's compensation data designed to identify pay gaps between employees in similar roles that can't be explained by legitimate factors like experience, performance, or seniority. The goal is to surface unexplained pay differences — disparities that may reflect historical bias, inconsistent negotiation practices, or systematic undervaluation of work performed by women, people of color, or other protected groups — and correct them. Pay equity audits are distinct from pay gap reporting: a pay gap measures the average difference in pay between two groups (e.g., women earn $0.82 for every dollar men earn), while a pay equity audit controls for role-relevant variables to isolate unexplained differences.

Pay equity audits use regression analysis to control for legitimate pay-influencing factors: job level, role, geographic market, tenure, performance ratings, and education or certifications where relevant. What remains after controlling for these factors is the 'unexplained gap' — the portion of the pay difference between demographic groups that isn't accounted for by legitimate variables. This unexplained gap is what most pay equity audits seek to identify and remediate. A company may find, for example, that after controlling for role and level, women in engineering earn 4.3% less than men — a statistically significant gap that requires investigation and correction.

Pay equity audits were historically conducted confidentially by employers, often in anticipation of litigation or at the direction of outside counsel (sometimes with attorney-client privilege claimed to protect the findings). The spread of pay transparency laws — which now require employers in Colorado, California, New York, Illinois, and elsewhere to disclose salary ranges in job postings — has accelerated both the voluntary adoption of pay equity programs and regulatory scrutiny. Some jurisdictions (Massachusetts, Rhode Island, Illinois) and regulators are moving toward requiring proactive reporting of pay equity data, and the SEC has increased ESG disclosure expectations for public companies. For employees, the practical implication of pay equity audit laws and company programs is that asking 'how do I know if I'm being paid equitably?' is increasingly answerable — through pay transparency disclosures, public company filings, and direct conversations with HR framed around the organization's stated equity commitments.

What a Pay Equity Audit Looks At

  • Controlled pay gap: the difference in pay between demographic groups after controlling for role, level, experience, and performance. Distinct from the raw pay gap, which doesn't account for these factors.
  • Job architecture: audits require clear job levels and descriptions to group 'similarly situated' employees for comparison. Poor job architecture makes pay equity analysis unreliable.
  • Regression analysis: statistical modeling identifies which factors explain pay and quantifies any unexplained gap. Results are typically expressed as a percentage — 'women earn X% less than men after controlling for legitimate factors.'
  • Remediation: identifying the gap is only useful if followed by action — adjustments to bring pay into alignment, typically done in an annual cycle and funded through a remediation budget.
  • Proactive vs. reactive: audits done proactively and remediated regularly reduce legal exposure; audits done only in response to complaints or litigation are reactive and more expensive.
  • Privilege considerations: many employers conduct audits under attorney-client privilege to protect findings from discovery in litigation. This practice is legally complex and courts vary on whether privilege actually protects the results.

What to Do If You Suspect a Pay Equity Issue

With pay transparency laws now publishing salary ranges for your role in an increasing number of states, employees have more data than ever to identify potential pay inequities. If you believe your pay is below what colleagues in equivalent roles earn — particularly if there's a demographic pattern — several options exist. First, research the market rate for your role using published ranges, salary databases, and the posted range if your employer is subject to disclosure laws. Then consider raising a conversation with HR or your manager framed around the data: 'I've been researching compensation for my role and level and wanted to understand how my pay is positioned.' This avoids the defensiveness of a discrimination frame while opening the door to a data-driven conversation. If the response is dismissive or you have concrete evidence of a discriminatory pattern, filing a complaint with the EEOC or your state's equal employment agency is the formal mechanism — and most do so after exhausting internal options.

Example

A large retail company conducts an annual pay equity audit with an external consultant. The regression analysis finds a 5.8% unexplained pay gap for women in store management roles compared to men at the same level, with equivalent tenure and performance ratings. HR identifies 47 store managers whose pay is statistically below the expected range after controlling for legitimate factors. The company funds a $2.1 million remediation, adjusting those 47 employees' pay to within the expected range at their next pay cycle. The company publishes a brief summary of findings and actions in its annual diversity report, citing the audit as part of its ongoing commitment to pay equity.
