"One in four employees missed out and did not save enough to receive their full employer match. In 2014, the average amount of employer match not received was $1,336 per employee, which equates to an extra 2.4 percent of annual income missed. Over 20 years, this annual loss adds up to $42,855 per plan participant. In total, over 1 million employees in [the] study sample left more employer matching contributions unclaimed ($1.4 billion) than claimed ($1 billion).... [N]ationwide American employees are passing up approximately $24 billion annually in employer matching contributions by not saving enough to receive their full employer 401(k) match. Lower-income and younger employees were much more likely than others to miss out on at least part of their employer matching contribution."
