Think a million dollars is enough to get you through retirement? Think again.

New research from Scottrade Advisor Services show most (71 percent) registered investment advisors put a much higher price tag on the cost of retirement–much higher than what most Americans perceive is going to be enough.

"While there are no definitive answers on how much money various generations will need to save for retirement, it is clear that the majority of RIAs feel the $1 million goal is not enough for most families," said Craig Hogan, Scottrade director of customer intelligence, customer relationship management and reporting, in a released statement. "According to the majority of RIAs, younger generations, especially, need to set their retirement goals higher than other generations and start saving as early as possible. This can be attributed to a variety of factors, including the uncertain future of Social Security."
