The average woman could spend an estimated 70 percent of her retirement check on health care costs, according to a recent study by the Nationwide Retirement Institute. The average man fares better, but still uses nearly half of his benefits to cover medical expenses.
Here's how the Nationwide analysis reached its disturbing estimates: It assumed a woman with a life expectancy of 88 married a man who would live to 85 and they both claimed Social Security at 62, which is the earliest and most popular age to file for retirement benefits, regardless of gender.
More than half of elderly married couples and nearly 75 percent single retirees depend on Social Security for the majority of their income in retirement.
"Women disproportionately rely on Social Security in retirement," said Nancy Altman, co-director of Social Security Works, which advocates for the expansion of the program. In fact, roughly two-thirds of Social Security beneficiaries age 85 and older are women.
