A handy interactive tool allows users to work out the precise gender pay gap at their local NHS organisation.
Women working for the NHS earn 25 per cent less than their male colleagues, according to data on more than a million employees.
And 92 per cent of trusts and clinical commissioning groups across England pay women less than men, figures show.
The data comes after the Government ordered all companies with more than 250 employees to state their gender pay figures.
Theresa May vowed yesterday to end the 'burning injustice' of men earning more than women within a generation.

The new tool, by Rangewell, uses the average hourly rate of pay that trusts and CCGs reported to the Government's Gender Equality Office.
NHS Northern, Eastern and Western Devon CCG, which is responsible for providing health services to 880,000 people, was the worst offender.
The body pays women 40.7 per cent less than men on average - the equivalent of a woman earning 59p compared to a man's £1.
Queen Victoria Hospital Foundation Trust, located in East Grinstead, West Sussex, was the only other organisation to have a gap above 40 per cent.
At the other end of the scale, women working at Liverpool Community Health Trust earn 17.3 per cent more than men, on average.
Just seven NHS organisations, out of the 211 that were included, pay women and men the same, according to the interactive tool.
Some 92 per cent of trusts and clinical commissioning groups across England pay women less than men, according to figures

Firms with more than 250 staff were given a deadline of midnight on Wednesday to submit gender pay data to the Government.
An analysis of the data, from more than 10,000 companies, revealed almost 80 per cent of large firms pay men more than women.
This means the NHS is a significant offender - with only eight per cent of trusts and CCGs paying women the same or better.
The gender pay gap is calculated as the difference between the average salaries of men and women – it is not the same as equal pay.
Data from NHS Digital shows the gender pay gap among full-time doctors is 15 per cent, but rises to 26 per cent when part-time work is included.
The average earnings for all male doctors is £88,613, compared with £65,236 for women, according to The Times.
And for porters and nurses this gap shrinks to 4 per cent.
Overall among NHS staff, full-time men earn an average of £37,470 and women £28,702.
But this rises to a gap of 36 per cent taking part-time work, bonuses and overtime into account, with the average man earning £44,166 compared with £28,017 for women.
Sally Davies, of the Medical Woman's Federation, told the BBC that the NHS finding 'reflects the fact that men are more likely to make it into senior positions. It is the same issue we have seen in the rest of the economy.'
Ms Davies added: 'It raises serious questions for the NHS and government. I would like to know what they are going to do about it.'
A Department of Health and Social Care spokesperson said: 'We are committed to ensuring that our hardworking NHS staff are rewarded fairly and equally for their work regardless of gender.
'The Department is working closely with NHS organisations to support them in closing their gender pay gaps and has committed to an independent review of the gender pay gap in medicine.'
Danny Mortimer, chief executive of NHS Employers, said: 'Like employers in other sectors the gender pay reports show that employers in the NHS still have further work to do.
'It is disappointing that there is any gender pay gap in the NHS - but organisations in the NHS are working to address the underlying issues moving forward.'
