A good concept book, with an important topic, but when it comes to personal finances I think it is limited. The authors did a great job in explaining the power of making additional payments on principal debt, and then discuss some of the benefits of budgeting. But where I think the book comes up short is it does not adequately address other areas of personal finance, like investments, insurance, tax issues, tuition concerns, etc. Now, all that being said, if someone did nothing else than then take the advice offered in this book they would be well ahead of most Americans, but it does have some holes to consider. Concerning the software, I found it helpful but limited. I already have a program to track my expenses, and it does much more than the spreadsheets provided by the authors. I felt the most powerful part of the software was the portion that showed the effects of debt reduction on savings. I have not had a chance yet to verify those calculations, but that alone has got me thinking more than anything else in the book.
In summary, this is a good book. It is a good reminder of the power of debt reduction. It follows closely principles taught in the "One for the Money," but is more limited than that pamphlet. However, I believe it would be wise to consult other personal finance resources to get a fully view of wise financial concepts.
