Salary disparities between men and women are one reason for the 257-year economic gap between men and women documented by the World Economic Forum’s 2020 Global Gender Gap Report. And if you’re not negotiating your salary -- in fact, one survey found that only 16 percent of female respondents said that they always negotiate compensation when a job offer is made or during performance evaluations[1] -- you may be unwittingly contributing to this deficit. Negotiating a salary can be tricky, but it doesn’t have to be intimidating. The next time you’re up for a new job or a promotion, head into your salary talks armed with the following tips.

Do your homework

Prepare for a salary negotiation like you would for a test — with lots of prep. Search sites like Payscale and Glassdoor to learn what people in similar roles and with similar educational backgrounds and experience are earning, and then formulate your own income request based on that information. Also take into consideration how long you’ve been at the company or your relevant work experience and the unique talents you bring to the table.

Bring backup

Knowing your worth is one thing, but it’s essential to provide backup. Head into your salary talk with proof of your value: printed accolades you’ve received from co-workers or bosses, lists of achievements and awards, and quantifiable documentation of money you’ve raised for the company or clients and work you’ve brought in.

Ask for help

Consider asking your manager or mentor for advice or a letter of support if you’re making a move internally and get your co-workers to document your value to the team and the company in a LinkedIn recommendation.
