All the Single Ladies, All the Single Ladies: Start planning now for your financial future!

A much-anticipated report released Tuesday shows the roughly 55 million single women in the U.S. are in a far more precarious position than married women – as well as all men – when it comes to retirement savings. As a result, they may face serious financial hardship as they age.

About 40 percent of unmarried women have saved less than $1,000, according to the 2016 Retirement Confidence Survey by the Employee Benefits Research Institute and Greenwald and Associates. That's significantly higher than the 34 percent of unmarried men, 22 percent of married women, and 12 percent of married men with a similar, meager amount in savings and investments.

Single women "lack the financial security of a dual-earner household to support their retirement savings, along with the added income associated with dual Social Security and a spouse's retirement benefits," said Kim Mustin, co-head of global distribution at BNY Mellon Investment Management.

"They might also be carrying housing costs with a rental or home mortgage. If they are single mothers, they might have the sole financial responsibility of the cost of raising children," she said.

Studies have shown women generally don't think they will need as much money as men, despite the fact that women tend to live longer and face higher expenses in retirement.

About 36 percent of unmarried women and 29 percent of married women think they'll need to accumulate less than $250,000 for retirement, according to the EBRI survey. Meanwhile, the majority of men believe they should have saved $500,000 or more.

"Women may not fully comprehend the long-term costs of inflation affecting necessities like food, housing, health care and transportation," Mustin said. "Many of us live in the moment and don't think about what tomorrow will bring and the implications an unexpected illness or injury can have on a person's savings."

Unequal treatment in employment also puts women at a disadvantage, as they are more likely than men to work part-time and interrupt their careers to take care of family members. Lower earnings also impact women's ability to maximize employer-sponsored and other retirement savings plans.

Across all age groups, women have substantially less income in retirement than men, according to another report from the National Institute on Retirement Security. For women age 65 and older, their income is generally 25 percent lower than that of men. As men and women age, the gap widens to 44 percent by age 80.
