CHARLOTTE, N.C. -- The way Millennials save for retirement may end up costing them in the long run.

• A survey from PNC Bank says Millennials contribute to their retirement through saving rather than investing
• Some say using the market is the best way to build wealth
• Recommended to save an emergency fund, with as much as six-months salary

A new survey from PNC Bank says Millennials contribute to their retirement through saving rather than investing.

Senior Vice President of PNC Investments Orlando Cruz says, while saving is a good start, using the market is the best way to build wealth.

“You want to have access to the capital markets, you want to have a solid financial plan. That is how you're going to build wealth,” Cruz said. “Saving is a great way to start and this generation, amongst many, is well ahead of the game in that case.”

Cruz also recommend saving an emergency fund, with as much as six-months salary. Only about half of Millennials said they have an emergency fund.
