Chances are, you’re more confident about your prospects for a comfortable retirement today than you were between 2009 and 2013, when retirement confidence was in the doldrums. According the recently released Retirement Confidence Survey, published annually by the Employee Benefit Research Institute, the percentage of workers very confident about having enough money for a comfortable retirement increased from 13 percent in 2013 to 22 percent in 2015, and leveled off at 21 percent in 2016.
