Benefits combined are worth about 30 percent of your total compensation package, according to the U.S. Department of Labor. They cost employers an average of $8.81 per hour worked in December 2008.

Suppose you're offered an annual salary of $50,000. Your benefits package would theoretically be worth more than $15,000, so your total compensation would be valued at roughly $65,000.

Take a look at how much your benefits package adds to your overall compensation, based on the Department of Labor's most recent estimates.
