Women face some unique challenges when it comes to saving for retirement.For starters, they live longer. A 65-year-old woman will outlive her male counterpart by 2.3 years. That means women need to save more, especially single women who won’t inherit anything from a spouse. A recent study found 80% of all women end up alone during their final years. With a longer life comes a higher chance of illness, and more medical costs. Chronic and terminal diseases that afflict a person later in life can take a huge chunk out of a savings account. Women are less likely to be prepared. Even high-net-worth women are less likely to have long-term care insurance. Women earn less doing the same work. Income disparity is improving, but women are paid about 82% of what the average working man in the same job receives. Women earn about a third less than men over their lives. Women are also more likely to take time away from work to raise kids or care for elderly parents. Others may seek more flexible employment so they can spend more time at home. This results in gaps in women’s work years, with corresponding reductions in Social Security benefits. Financial planners should be making their female clients aware of these challenges and offering suggestions for dealing with them.
