33  Internal and External Equity in Compensation Systems

Equity in compensation is central to designing fair and motivating pay systems. Employees compare their pay not only within the organization (internal equity) but also against external labor markets (external equity). According to Milkovich, Newman & Gerhart (2023), Gerhart & Rynes (2003), and Sharma & Sharma (2024), maintaining a balance between these two forms of equity ensures employee satisfaction, retention, and organizational competitiveness.

33.1 Internal Equity

Meaning

• Internal equity refers to fairness in compensation within an organization.
  
• Employees perceive equity when jobs of similar value receive comparable pay.

Determinants

• Job Evaluation: Systematic assessment of the relative worth of jobs.
  
• Skill, Effort, and Responsibility: Consideration of competencies and contributions.
  
• Organizational Hierarchy: Pay differentiation across levels based on responsibilities.

33.2 External Equity

• Employees compare their pay with peers in similar roles outside the organization.

Determinants

• Market Surveys: Wage and salary surveys help assess industry benchmarks.

33.3 Balancing Internal and External Equity

Organizations must strike a balance between paying fairly internally and remaining competitive externally.

Strategies

• Pay Structures: Designing salary ranges and grades to reflect internal job values and external benchmarks.
