With the deadline for British companies to disclose their gender pay gaps just days away, thousands of firms have yet to submit their figures.
Three-quarters of firms pay men more than they pay women on average, based on those who have reported so far.
To find out the pay gap at your company, use the lookup below.

Understanding the terminology
Median pay gap
The median pay gap is the difference in pay between the middle-ranking woman and the middle-ranking man.
If you line up all the men and women working at a company in two separate lines in order of salary, the median pay gap will be the difference in salary between the woman in the middle of her line and the man in the middle of his.
Mean pay gap
The mean pay gap is the difference between a company’s total wage spend per woman and its total spend per man.
The number is calculated by taking the total wage bill for each and dividing it by the number of men and women employed by the organisation.
Pay gap v equal pay
The gender pay gap is not the same as unequal pay.
Unequal pay is giving women less than men for the same work. That has been against the law since the Equal Pay Act was introduced in 1970.
A company’s gender pay gap can also be caused by other things – for example, fewer women in senior or highly-paid roles or more women in part-time jobs.
This article is based on the difference in what men and women are paid per hour, but there are other ways of calculating the gender pay gap: the Office for National Statistics releases annual figures here.
How does the BBC calculator work?
The individual company data reflects the information submitted by companies to the Government Equalities Office as of 1 April.
The data submitted each year is based on figures drawn from a specific date – called the “snapshot date” – the previous year. For businesses and charities, 5 April is the snapshot date, while 31 March is the snapshot date for public sector organisations.
All gender pay gap figures in this article reflect the hourly median pay gap for all employees.
