Here’s some good news for female workers: There is a way for you to earn salaries that, on average, are roughly equal to your male colleagues. The bad news? You’ll need to earn an additional academic degree to do so.

That’s one of the main takeaways of a new wage gap report from the Georgetown Center on Education and the Workforce, which finds that at every education level women have to earn one additional degree in order reach average salaries in line with men’s averages.

Women with an associate’s degree, for example, earn an average salary of $43,000—close to (though still lower than) the $47,000 earned by men with just a high school diploma. Women with a bachelor’s degree earn $61,000 on average, just slightly above the $59,000 for men with associate’s degrees. And finally, women with a master’s degree or higher bring in an average $83,000 a year—while men need only a bachelor’s degree to report average earnings of $87,000.
