According to a study by the Boston Consulting Group, 89% of employees want help figuring out how best to invest in their 401(k) plan. And, 84% want help calculating how much money they need and/or will have at retirement.
Sorry for another blatant self promotion, but that is why I wrote my first book. So, I wonder why "The 401(k) Cookbook" does not sell better? 401(k) investors can figure out the answer to both questions in about a half hour using this book.
