Pay Gap Calculator

The underlying mathematics of the pay gap relies on comparing median earnings between a reference demographic group (frequently white men) and other demographic subgroups within the same occupation. The primary formula calculates the wage ratio as:

Wage Ratio = (Subgroup Median Earnings / Reference Group Median Earnings) * 100

Additionally, the calculator computes metrics like free months or free days of work, representing the unpaid labor time a worker provides due to wage disparities. This is derived by taking the absolute wage difference and projecting it across a standard annual work calendar to show how long an individual would need to work for free to bridge the earnings gap.

Imagine a data analyst earning a wage of $75,000 annually. Suppose the median benchmark wage for white men in this specific occupation is $95,000, while the median wage for the user's specific demographic profile is $75,000. First, we compute the percentage gap:

Wage Gap Percentage = (($95,000 - $75,000) / $95,000) * 100 = 21.05%

Next, to determine the 'free months' or unpaid time equivalent of this $20,000 difference based on a monthly salary of $7,916 for the benchmark group:

Free Months = $20,000 / ($95,000 / 12) = 2.53 Months

This means the worker effectively performs over two and a half months of labor uncompensated relative to the benchmark group's median earnings.

When reviewing compensation metrics, always ensure you compare roles with equivalent skill requirements, geographic locations, and levels of experience to maintain data accuracy. Keep in mind that national median figures serve as macro-level indicators and may not fully capture company-specific internal equity. Use these findings as a starting point for career negotiations, market research, and understanding broader socioeconomic trends.
