About Gender Pay Gap Calculator

The gender pay gap is the difference between men's and women's average pay expressed as a percentage of men's pay. Mean and median are both reported because the mean is pulled by a small number of very high earners while the median reflects the typical employee.

Formulas

Mean gap

Mean gap % = (Mean male pay - Mean female pay) / Mean male pay x 100

Median gap

Median gap % = (Median male pay - Median female pay) / Median male pay x 100

Assumptions and limits

  • The result is derived only from the 4 inputs listed above. Anything not among them is not part of the calculation.
  • In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
  • Figures are rounded for display to 4 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

Is a pay gap the same as unequal pay?

No. Unequal pay is paying differently for the same work and is unlawful in most jurisdictions. A pay gap can arise from occupational and seniority distribution even where equal pay holds.

Why report both mean and median?

Because a large gap between them tells you the problem is concentrated at the top of the distribution rather than spread across all levels.
