According to recent data from the Employee Benefit Research Institute (EBRI), men and women do not differ that much when it comes to retirement planning.
According to EBRI, men and women are equally likely to say they (and/or their spouse) have saved for retirement and to say they are currently saving for retirement. Women are also just as likely as men to report they are offered and contribute to a workplace retirement savings plan. Both men and women were also equally likely to indicate they have attempted to calculate how much they would need to have saved to retire successfully.
One area in which there was a difference comes lies in retirement confidence. Men are much more likely than women to feel confident about having enough money to live comfortably during their golden years.
