Many Americans struggle to save for retirement, but the gender wage gap makes the prospects for women even more dire: The average woman must save $1.25 for every $1 a man invests to build an equivalent nest egg, a new study shows. For every $1 men earned in 2015, women, on average, made 80 cents, up from 77.5 cents in 2007, according to an analysis of the latest data available from the U.S. Census Bureau.
