More than ever, young adults today are more likely to live at home with their parents--and it's not such a bad thing.

The decision to move back home actually helps Millennial to grow their wealth--that is, only if they use the money they saved money to start invest. Fidelity's second annual Millennial Money Study, a survey of 305 adults aged 25 to 35, found that 21 percent live at home with their parents (compared to the 14 in 2014). For those living on their own, almost half said they needed financial assistance from their parents (i.e., bills for cell phone, grocery bills, general leisure activities, and utility.

Indeed, having a financial cushion comes with a handful of benefits. But there are two other factors that could contribute to a future with higher wealth:

  1. Young adults today are much more likely to have financial role models: 65 percent of the Millennial respondents said their parents provided a good example for a successful financial future, compared to 56 percent of Gen Xers and Baby Boomers.

  2. Perhaps aided by the parental safety net, 85 percent of Millennials started saving this year (compared to the 77 percent in 2014. They have also set aside a higher amount ($9,100 on average) for unexpected costs than earlier generations.

Being around someone who is smart with his or her money teaches you how to be financially savvy (i.e., knowing how to avoid common pitfalls, where and how much of your money to invest). However, in an economy where interest rates have been extremely low (and savings accounts yielding anemic returns), simply parking money in a bank isn't enough for Millennials. The secret is getting the money work for them. Investing is the best place to start, but the Fidelity survey shows that only nine percent of Millennials see themselves doing so.

"Many young adults are interested in investing, but sometimes feel hesitant in taking that initial step," says Fidelity Investments senior vice president, Kristen Robinson.

The financial institution suggests being more transparent with parents about their own savings and investments in order to get the right advice. Fidelity also recommends reading educational sites to help make the jump into buying and selling financial assets.

"Finding ways to turn positive savings habits into positive investing strategies will help Millennials gain greater confidence, and ultimately financial independence," Robinson added. Other sites like NerdWallet, Finimize, Wealthfront, and Betterment are also geared to helping young people understand the industry and get a start in investing.
