Workers Cite Biggest Financial Planning Regrets: Saving Too Little ... DES MOINES, Iowa--(BUSINESS WIRE)--Sept. 13, 2006--When it comes to saving for retirement, are American workers and retirees a day late and a dollar short? According to the latest Principal Financial Well-Being Index(SM), nearly half of American adult workers (45 percent) and a third of retirees (32 percent) surveyed indicated that their biggest financial planning regret was they started saving too late. Around one-quarter of respondents (27 percent of workers; 22 percent of retirees) said they regretted saving too little in their early working years. Others said they had regrets over going it alone and managing on their own when it comes to financial planning (9 percent of workers and 10 percent of retirees). The index, which surveys American adult workers at growing businesses with 10 to 1,000 employees, is released each quarter by the Principal Financial Group(R) and conducted by Harris Interactive(R).
