One of the best things about this is that they show you the entire planner on the website so that you can decide if it's the right tool for you before purchasing. No surprises. You're already familiar with it before starting! Very easy to enter data and the results show income, taxes, expenses, and needed withdrawals year by year. Try different S.S. claiming ages and investment return %'s to find what is right for you, and you're done. Valuable, detailed information, all laid out logically. Great Planning tool - and excellent customer service!
