Adverse Impact Calculator

This calculator helps determine if there is an adverse impact on a protected group in hiring, promotion, or other selection processes.

Input Parameters

Calculation Results

Selection Rate

Overall: 0%

Protected Group: 0%

Where:
Selection Rate = (Selected Candidates / Total Applicants) * 100
Protected Group Rate = (Selected in Protected Group / Total in Protected Group) * 100

Adverse Impact Test

Result: N/A

If Protected Group Rate is less than 80% of Overall Rate, adverse impact is indicated.

Formula

Adverse Impact = (Overall Rate - Protected Group Rate) / Overall Rate

Where:
Overall Rate = (Selected Candidates / Total Applicants) * 100
Protected Group Rate = (Selected in Protected Group / Total in Protected Group) * 100

Adverse Impact Calculator Calculator Usage Guide

Learn how to use the Adverse Impact Calculator to assess selection processes for fairness and compliance.

How to Use the Calculator

  1. Enter the total number of applicants who participated in the selection process.
  2. Enter the number of candidates who were selected from the total pool.
  3. Enter the total number of individuals in the protected group who applied (e.g., women, minorities, veterans).
  4. Enter the number of individuals from the protected group who were selected.
  5. Click the "Calculate" button to determine if adverse impact exists.

Understanding the Results

The calculator provides three key outputs:

  • Selection Rates: Shows the percentage of candidates selected overall and within the protected group.
  • Adverse Impact Test: Indicates whether there is a statistically significant difference between the selection rates that suggests adverse impact. If the protected group rate is less than 80% of the overall rate, adverse impact is generally considered to exist.
  • Adverse Impact Formula: Shows the mathematical calculation behind the assessment.

Principles of Adverse Impact Assessment

Adverse impact analysis is a statistical tool used to measure whether a selection process has a disproportionately negative effect on members of protected groups. The calculator uses the four-fifths rule (where the selection rate for a protected group is less than 80% of the selection rate for the overall group) as a common benchmark for identifying potential adverse impact.

Limitations

This calculator provides a preliminary assessment and should be used as part of a comprehensive evaluation. It does not consider other factors that might influence selection outcomes, such as differences in qualifications or job-related skills between groups.
