Saving for retirement isn’t easy for anyone, what with wage growth slow and underemployment stubbornly high.

For women, it’s even harder.

According to a recent study by the Transamerica Center for Retirement Studies, 62 percent of women said they were saving for retirement, but just 15 percent said they were saving enough; 22 percent were barely saving at all. That means 85 percent of women aren’t saving enough money to support themselves in retirement.

There are a number of reasons why women fall behind in saving for their post-career lives, ranging from lower pay to taking time off from the workforce.
