Male fundraisers are being paid an average of 12 per cent more than their female colleagues, a survey by a third sector recruitment agency shows.
TPP Not for Profit polled 390 fundraisers from 148 organisations during June for its Fundraising Salary Survey 2013.
The results show that, on average, men in fundraising are paid £43,121, while the average salary for women is £38,418.
The difference in pay becomes bigger in more senior roles. At director level, men are paid an average of £61,868, 6 per cent more than their female peers, who are paid an average of £58,435.
But at more junior levels, women are paid more than men, the survey found. At officer/executive level female fundraisers are paid 6 per cent more than their male counterparts - an average of £27,170 compared with £25,607.
The agency did not ask respondents about their gender in its previous survey, carried out in July 2012, so there is no year-on-year comparison.
Figures from the National Council for Voluntary Organisations show that women account for 73 per cent of the overall fundraising workforce.
A report based on the agency's findings says the average overall salary increased by 3 per cent over the course of the year, from £38,485 to £39,627.
"In the current financial climate, charities are under pressure to find excellent fundraising staff, who will help them to diversify their income streams now that government funding has declined dramatically, which has helped to boost fundraising salaries," the report says.
But the increase in salaries has slowed from the 9 per cent reported in the 2012 survey.
