Gender Pay Gap

By TapTalent Editorial TeamUpdated

Definition

Gender pay gap is the difference between the average (or median) pay of men and women across an organization or labor market, expressed as a percentage of men's pay. It compares all men with all women regardless of job, so it reflects both unequal pay for the same work and differences in who holds which jobs.

Also called: Gender wage gap, Pay gap, Unadjusted pay gap

Formula

Gender pay gap (%) = (Men's median hourly pay − Women's median hourly pay) ÷ Men's median hourly pay × 100

Median hourly pay
The middle hourly rate when all employees of that gender are sorted by pay. Calculate the mean (average) as well; most reporting rules ask for both.
Hourly pay
Ordinary pay for the period divided by hours worked, so part-time and full-time employees can be compared fairly. Bonus pay is usually reported separately.

Worked example

A regional bank's operations center has 260 employees. Women's median hourly pay is $23.40 and men's is $26.00. Gender pay gap = (26.00 − 23.40) ÷ 26.00 × 100 = 10%. Looking at quartiles, women make up 72% of the lowest-paid quarter (mostly processors and tellers) and 41% of the highest-paid quarter (managers and analysts). That job mix, not unequal pay for the same role, explains most of the gap.

Gender pay gap vs equal pay

These are related but different, and confusing them leads to bad conclusions.

Equal pay is about men and women in the same or substantially equal jobs being paid the same. Unequal pay for equal work is illegal under the US Equal Pay Act of 1963 and Title VII of the Civil Rights Act of 1964, and under similar laws in most countries.

The gender pay gap compares all women with all men across the organization. A company can pay men and women identically in every job and still have a large gap if women are concentrated in lower-paid roles and men in higher-paid ones.

That is why the gap is useful: it points at representation, promotion and job design issues that an equal-pay audit alone would miss. The broader discipline of checking both is pay equity.

Raw vs adjusted pay gap

The raw (unadjusted) gap is the simple calculation above. It is what most reporting laws require.

The adjusted gap controls for factors such as job level, role, location, tenure and performance, usually through regression analysis. It estimates how much of the gap remains between similar people in similar jobs. An adjusted gap close to zero with a large raw gap means the problem is mostly about which jobs men and women hold. A meaningful adjusted gap points to unequal pay for comparable work, which carries much more legal risk.

Report both internally. Leaders who see only the adjusted figure tend to conclude there is no problem; leaders who see only the raw figure tend to reach for across-the-board raises that do not fix the cause.

Gender pay gap reporting rules

United Kingdom. Since 2017, employers in Great Britain with 250 or more employees must publish annual figures: mean and median gender pay gap in hourly pay, mean and median bonus gap, the proportion of men and women receiving a bonus, and the proportion of men and women in each pay quartile.

European Union. The EU Pay Transparency Directive (Directive (EU) 2023/970) had to be written into national law by June 2026. It phases in gender pay gap reporting by size: employers with 250 or more workers report every year, and those with 100 to 249 every three years, with the first reports starting in 2027 for larger employers. If reporting shows a gap of at least 5% in any category of workers that the employer cannot justify with objective, gender-neutral criteria and does not fix within six months, the employer must carry out a joint pay assessment with worker representatives.

United States. There is no federal gender pay gap publication requirement. Some states require pay data reporting: California, for example, requires private employers with 100 or more employees to file annual pay data reports broken down by job category, sex and race or ethnicity, and Illinois has a similar equal pay registration process. Rules vary by state and country, so confirm the requirements where you employ people.

What drives the gap in high-volume workforces

In contact centers, retail, healthcare support and banking operations, the frontline workforce is often majority women while supervisors, technical roles and senior leaders are more often men. Common drivers:

  • Promotion rates. If women make up 65% of agents but 40% of team leaders, the funnel between the two is where to look.
  • Shift and overtime premiums. Premium-paid night shifts and overtime can skew toward employees without caregiving responsibilities.
  • Starting pay negotiation. Off-scale offers for people who negotiate harder, often in roles where men are hired more.
  • Job design. Roles held mostly by women may be graded lower even when the skill and responsibility are comparable. Gender-neutral job evaluation checks for this.

How to reduce the gap

Start with an analysis by grade, job family and site, and then fix causes rather than symptoms. Set starting pay from structured ranges instead of negotiation and prior salary. Track promotion rates into first-line leadership by gender each quarter. Make shift premiums and overtime opportunities transparent and fairly allocated. Run an adjusted pay analysis every year and correct unexplained individual differences. Publish the action plan along with the numbers; a gap figure without a plan invites the worst interpretation.

Frequently asked questions

What is the gender pay gap?

It is the percentage difference between men's and women's average or median pay across an organization or economy. It reflects both unequal pay for equal work and differences in the jobs men and women hold.

How do you calculate the gender pay gap?

Subtract women's median hourly pay from men's median hourly pay, divide by men's median hourly pay and multiply by 100. Repeat with mean pay. Use hourly pay so part-time and full-time employees are compared fairly.

Is the gender pay gap the same as unequal pay?

No. Unequal pay means men and women are paid differently for equal work, which is illegal. The gender pay gap can exist even when equal pay is fully respected, because of differences in job level and representation.

Which employers must do gender pay gap reporting?

In Great Britain, employers with 250 or more employees. In the EU, employers with 100 or more workers on a phased schedule under the Pay Transparency Directive. In the US there is no federal requirement, but some states require pay data reports.

What is a pay gap analysis?

A pay gap analysis calculates raw gaps by gender and often other characteristics, breaks them down by grade, role and location, and uses statistical methods to estimate how much of the gap remains after accounting for legitimate factors.
